Description

A box, a handle, a suspender and an operating method thereof

Technical Field

The invention belongs to the technical field of medical equipment, and in particular relates to a cassette, a handle, a suspender and an operating method thereof.

Background technique

Benign prostatic hyperplasia (BPH) is one of the most common medical conditions affecting men, especially older men. The prostate gland continues to enlarge throughout a person's life. In some men, the prostatic capsule surrounding the prostate gland may prevent the prostate gland from further enlarging. This causes the inner area of the prostate gland to press against the urethra. This pressure on the urethra increases the resistance to urine flowing through the area of the urethra surrounded by the prostate gland. As a result, the bladder must exert more pressure to force urine through the increased urethral resistance. Chronic overstraining causes the muscle wall of the bladder to remodel and become stiffer. This increased urethral resistance and increased stiffness of the urine stream, along with hypertrophy of the bladder wall, can lead to a variety of lower urinary tract symptoms (LUTS), which can significantly reduce the patient's quality of life. These symptoms include a weak or intermittent urine stream during urination, straining during urination, hesitation before urination begins, a feeling that the bladder is not completely empty even after urination, dribbling or leaking urine at the end of urination, increased frequency of urination, especially at night, and urgency. To treat the problem of prostate enlargement, mechanical devices that facilitate surgery have been designed to assist medical personnel.

Chinese patent publication number CN114286646A relates to a device for transferring mechanical energy in a handle to a cassette to manipulate tissue or anatomical structure in a human or animal subject to treat a disease or condition. The handle and the cassette include a safety interlock device.

However, the suspension device designed in the prior art cannot simplify the surgical operation process to the greatest extent, and the entire operation process is still cumbersome. The operation in the prior art requires careful identification and opening of the corresponding locking mechanism before pressing the handle to perform the corresponding operation. After the corresponding operation is completed, the corresponding mechanism needs to be locked again. The operation is complicated and cannot provide maximum assistance to medical personnel. At the same time, it cannot guarantee the safety of the locked state of the box and the handle, nor can it maximize the avoidance of errors in surgical operations.

As shown in FIG. 1 to FIG. 3 , the present invention provides a suspension device, including a handle 100 and a cassette 200 mounted on the handle 100 . One cassette 200 can only complete one treatment. When a new treatment is performed, a new cassette 200 needs to be replaced.

The box 200 cooperates with the handle 100 to perform operations one by one, which are mainly divided into four operations. The handle 100 is opened once to perform one operation. After each operation is completed, the handle 100 will return to its original state, so as to facilitate the next operation.

Please refer to Figures 3-8. The cassette 200 includes a bracket 211, an outer sleeve assembly 208 mounted on the bracket 211, an implantation clip push rod 207 movably placed in the outer sleeve assembly 208, a puncture needle 203, a suture 202, a front clip 201, a cutter 206, a rear clip 204 and a push rod 205, an actuating assembly 214 movably mounted on the bracket 211 through a lower cover plate 220 of the assembly, and an actuating assembly 1 213 movably mounted on the bracket 211 through an upper cover plate 212 of the assembly, and an implantation clip push rod 207 mounted on the actuating assembly 1 213. Rod 207, puncture needle 203 and suture 202, front clip 201 is installed at the end of suture 202, suture 202 and front clip 201 are placed in puncture needle 203, push rod 205 and cutter 206 are installed on actuating assembly 214, rear clip 204 is located in front of push rod 205, push rod 205 and rear clip 204 are placed in cutter 206, wherein the outer surface of cutter 206 located above rear clip 204 is a blade, i.e., the position for cutting suture 202, and a box housing 209 is covered outside bracket 211 and installed on bracket 211.

The design of the box 200 simplifies the operation process, and the entire surgical process can be completed by sequentially operating the actuating assembly 1 213 and the actuating assembly 2 214. At the same time, the cooperation between the box 200 and the handle 100 further simplifies the surgical process, and the internal structure of the handle 100 automatically drives and performs the surgical operation in sequence by continuously opening the handle 100.

The actuating assembly 1 213 can drive the implantation clip push rod 207, the puncture needle 203 and the suture 202 to move, and the actuating assembly 2 214 can drive the push rod 205 and the cutter 206 to move. Therefore, when the handle 100 is opened for the first time, the actuating component 1 213 drives the clamp push rod 207, the puncture needle 203 and the suture 202 to move forward at the same time, and the clamp push rod 207 pushes the front clamp 201 forward at the same time; when the handle 100 is opened for the second time, the actuating component 1 213 drives the puncture needle 203 to retreat, and at the same time drives the suture 202 to be tightened, thereby driving the front clamp 201 to unfold; when the handle 100 is opened for the third time, the actuating component 214 drives the push rod 205 and the cutter 206 to move at the same time, the cutter 206 retreats, and the push rod 205 pushes the rear clamp 204 forward, so that the rear clamp 204 clamps the suture 202 and cuts the suture 202 at the same time, and the rear clamp 204 cooperates with the front clamp 201 to tighten the treatment part, thereby treating the problem of prostate hypertrophy.

Specifically, please focus on Figure 5. The outer sleeve assembly 208 includes a shell 2081, a mirror tube channel bracket 2084 installed on the shell 2081, a front end catheter 2085 is installed at the front end of the mirror tube channel bracket 2084, a clamping assembly is provided on the mirror tube channel bracket 2084, a puncture needle positioning catheter 2082 and a cutter channel bracket 2086 installed in the shell 2081 through a clamping assembly 209, the puncture needle 203 is placed in the puncture needle positioning catheter 2082, the cutter 206 is placed in the cutter channel bracket 2086, a puncture needle positioning seat 2083 installed on the puncture needle positioning catheter 2082, and a protective cover 2087 installed on the cutter channel bracket 2086 through the clamping assembly 209. The protective cover 2087 is used to protect the rear clip 204 to prevent the rear clip 204 from falling outside the outer sleeve assembly 208 in a non-treatment state.

Please refer to Figures 9 and 10, the clamping assembly 209 mainly clamps the workpiece by its own elastic function. The clamping assembly 209 includes a folding portion provided by the folding component itself, and the folding portion is made elastic by the folding component itself, so as to clamp the workpiece.

Please refer to Figure 10, a guide channel 2088 is provided in the puncture needle positioning seat 2083, and an opening 2089 is provided on the protective cover 2087; when the clamp push rod 207, the puncture needle 203 and the suture 202 are driven forward at the same time by the actuating assembly 213, the push rod 207, the puncture needle 203 and the suture 202 pass through the treatment component from the opening 2089 along the guide channel 2088, and the guide channel 2088 is designed to guide the movement route of the push rod 207, the puncture needle 203 and the suture 202.

Please focus on Figure 11. The actuating assembly 213 includes a wire actuating assembly 2131 and a needle actuating assembly 2132. The wire actuating assembly 2131 can drive the suture 202 and the guide push rod 207 to move, and the needle actuating assembly 2132 can drive the puncture needle 203 to move.

Please focus on Figures 11 and 8. The wire actuation assembly 2131 includes a clip push rod fixing member 21312, on which a push rod 207 is installed. The clip push rod fixing member 21312 is installed on a thread end fixing member 21311, on which a suture 202 is installed, and the thread end fixing member 21311 is provided with a slider 21313, and the slider 21313 is placed in a slideway 217 provided on the upper cover plate 212 of the assembly.

The needle actuating assembly 2132 includes a needle fixing member 21322, on which a puncture needle 203 is mounted. The needle fixing member 21322 is mounted on a slider 1 21321, and the slider 1 21321 is placed in a slideway 217 provided on the upper cover plate 212 of the assembly.

When the puncture needle 203 needs to be moved, the slider 1 21321 needs to be pushed to move along the slideway 217 ; when the suture 202 and the front clip 201 need to be advanced, the slider 2 21313 needs to be pushed to move along the slideway 217 .

Please refer to Figures 7 and 12. The actuating assembly 214 includes a rotating member 2144 movably mounted on the bracket 211 and the assembly lower cover 220. The push rod fixing member 2141 is located at one end of the rotating member 2144 away from the outer sleeve assembly 208, and the push rod fixing member 2141 is movably mounted on the track 219 in the assembly lower cover 220. The end of the push rod 205 is mounted on the push rod fixing member 2141. The cutter fixing member 2142 is located at the other end of the rotating member 2144. The cutter fixing member 2142 is movably mounted. On the track 218 inside the lower cover plate 220 of the component, the end of the cutter 206 is installed on the cutter fixing member 2142, and the cutter fixing member 2142 is connected to the push rod fixing member 2141 through a spring 2143; in the initial state, the rotating member 2144 limits the movement of the cutter fixing member 2142 along the spring 2143, the implant positioning safety 2145 limits the movement of the push rod fixing member 2141 along the spring 2143, and the implant positioning safety 2145 is movably installed on the lower cover plate 220 of the component.

When it is necessary to clamp the suture 202 and cut the suture 202 at the same time with the rear clamp 204, it is necessary to rotate the implant positioning safety 2145, which loosens the push rod fixing part 2141, thereby first pushing the push rod 205 to move, further driving the rear clamp 204 forward to clamp the suture 202, and then the push rod fixing part 2141, driven by the spring 2143, pushes the rotating part 2144 to rotate, thereby causing the rotating part 2144 to loosen the cutter fixing part 2142, and the cutter fixing part 2142 drives the cutter 206 to move backward to cut the suture 202.

The box 200 is also provided with a safety component and a locking component. The locking component is used to lock the box 200 on the handle 100, and can be easily replaced. Since the device is used for surgical treatment, there is a great demand for hygiene. In order to ensure the hygiene of the device, and since only some components of the box 200 contact the human body during the treatment process, after each use of the suspensor, only a new box 200 needs to be replaced, so the locking component is designed. At the same time, in order to avoid the box 200 falling off due to the misoperation of the locking component during the operation, the safety component is designed. The safety component is used to prevent the locking component from being opened in the case of accidental touch when the box 200 is locked on the handle 100.

Please refer to Figures 3 and 13-14. The locking assembly includes a knob 210 movably mounted on a bracket 211 and a box housing 209. The knob 210 is symmetrically provided with protrusions 2102, and the knob 210 is provided with a first clamp 2103 and a second clamp 2104. The bracket 211 is provided with a protrusion at a position corresponding to the first clamp 2103, and the bracket 211 is provided with a clamping groove 221 at a position corresponding to the second clamp 2103. When the knob 210 is rotated to the corresponding position, the locking assembly 210 is locked. After being placed, the protrusion blocks 2102 will be screwed into the handle 100, and at the same time, the clamping piece 1 2103 cooperates with the protrusion to clamp the knob 210 under the action of elastic force, and the clamping piece 2103 cooperates with the slot 221 to limit the excessive rotation of the knob 210. Therefore, the locking assembly can prevent the cartridge 200 from falling off the handle 100, and the cartridge housing 209 can prevent the cartridge 200 from moving left and right relative to the handle 100, thereby fixing the cartridge 200 on the handle 100.

Please refer to Figures 2-3 and 13. In order to ensure that the knob 210 will rotate to the corresponding position, an arrow 2101 is provided on the knob 210, an arrow alignment mark 2091 is provided on the cartridge housing 209, and an arrow alignment mark 1011 is provided on the handle 100. When the arrow 2101 is aligned with the arrow alignment mark 2091, the position is the corresponding position. Furthermore, there are two protrusions, one of which is for fixing the initial position of the knob, and the other is for fixing the locking of the knob. Position; first, rotate the knob 210 to the initial state. When in the initial state, the arrow 2101 is aligned with the direction of the arrow alignment mark 1011, and the cartridge 200 is pressed into the handle 100. At this time, the protruding block 2102 does not interfere with the handle 100. Then rotate the knob 210 so that the arrow 2101 is aligned with the direction of the arrow alignment mark 2091. At this time, the protruding block 2102 will be screwed into the handle 100, and at the same time, the clamp 1 2103 cooperates with the protrusion to clamp the knob 210 under the action of elastic force, thereby forming a locked state.

Please focus on Figures 14-16. The safety component includes a safety start strip 215 elastically mounted on the bracket 211 through a torsion spring 216, and an entrance 2106 provided on the knob 210, and a limiting groove 2107 is provided at the entrance 2106; when the knob 210 is in the initial state, the safety start strip 215 can enter the limiting groove 2107 from the entrance 2106 under the action of force; the safety start strip 215 is provided with a protrusion 2151, a display protrusion 2152 and a torsion spring mounting groove 2153, one end of the torsion spring 216 is mounted in the torsion spring mounting groove 2153, and the other end of the torsion spring 216 is mounted on the bracket 211; when the display protrusion 2152 enters the limiting groove 2107, after the knob 210 is rotated, the display protrusion 2152 cooperates with the torsion spring 216 to further limit the rotation of the knob 210.

The handle 100 is provided with an inclined surface 109 , and the inclined surface 109 is used to guide the safety activation strip 215 to enter the entrance 2106 when the cassette 200 is installed.

Specifically, the installation steps of the cartridge 200 on the handle 100 are as follows: first, the knob 210 is rotated to the initial state, and then the cartridge 200 is pressed on the handle 100. At this time, the inclined surface 109 guides the safety activation strip 215 into the limiting groove 2107. Since the protrusion 2151 and the display protrusion 2152 have entered the limiting groove 2107, the protrusion 2151 and the display protrusion 2152 cannot limit the rotation of the knob 210 at this time, but at the same time, the knob 210 can only be limited to rotate within the range of the limiting groove 2107. At this time, it is only necessary to rotate the knob 210 to the locked state, so that with the cooperation of the safety component and the locking component, the cartridge 200 can be locked on the handle 100, and the knob 210 can be locked at the same time to prevent its rotation from causing the cartridge 200 to fall off.

The box 200 also includes an identification component, which is used to display the specific process of the operation, so that the staff can easily distinguish the operation step they are in, and at the same time avoid the situation where the staff is unaware that the operation step is not fully completed, so that the staff can immediately understand the situation and carry out subsequent processing.

Please refer to Figure 3 for details. The identification component includes a safety lock display mark 2093 and a thread trimming mark 2092 provided on the cassette housing 209. The display protrusion 2152 is provided with a color identification one. Please refer to Figure 13 for details. The needle actuating component 2132 is provided with a color identification two 21323. When the safety component is in effect, the color identification one will be displayed at the safety lock display mark 2093. When the thread trimming is completed, the color identification two 21323 will be displayed at the thread trimming mark 2092. The identification component also includes a display hole 2105 provided on the button 210. Please refer to Figure 17 for details. The actuating component two 214 is provided with a color identification three 2146. When the color identification three 2146 is displayed in the display hole 2105, it indicates that the button 210 is in a locked state and the actuating component two 214 has not been started.

At the same time, the outer surface of the shell 2081 is provided with a scale; during the operation, the outer sleeve assembly 208 will be inserted into the patient's body, so that the operator can more clearly recognize the insertion depth of the cassette 200 and thus better assist in treating the patient, a scale is designed on the shell 2081.

The coordinated design of the safety component and the locking component in the box 200 can ensure the locked state of the box 200. The box 200 will not be opened before the corresponding opening action is performed, thereby improving the safety of the locked state. At the same time, the design of the box 200 simplifies the operation process. The entire surgical process can be completed by only operating the actuating component 1 213 and the actuating component 2 214 in sequence.

Please refer to Figures 18-20 and 26. The handle 100 includes a handle shell, a cover plate 123 installed on the handle shell, a transmission assembly movably installed on the cover plate 123, the transmission assembly is used to start the actuating assembly 1 213 and the actuating assembly 2 214, an indicator wheel assembly 121 and a handle locking device movably installed on the handle shell, a handle portion 108 elastically installed on the handle shell through a torsion spring 2 119 and a hinge hole 1081, the handle portion 108 is used to control the transmission assembly, and at the same time, a one-way transmission assembly is used in both the transmission assembly and the indicator wheel assembly 121 to ensure that the internal operation can only be transmitted in one direction, so that even if the operation is stopped halfway, all operations will not return to their original positions, thereby avoiding patient injuries caused by misoperation during treatment.

Please refer to Figure 2, the handle housing includes a left handle housing 101 and a right handle housing 102.

Please refer to Figures 18-19 and 21-22. The handle locking device includes a release button 103 movably mounted on the handle housing through a second spring 105, and a safety button 104 movably mounted on the handle housing through a third spring 106, wherein the safety button 104 is used to limit the position of the handle portion 108; wherein a spring accommodating groove 1033 is provided on the end of the release button 103, and the release button 103 is provided with a channel, the channel includes a vertical channel 1031 provided at the end of the release button 103, and a transverse channel 1032 provided in the middle of the release button 103, the vertical channel 1031 is connected to the transverse channel 1032, and at the same time, a protrusion block 1041 is provided on the safety button 104, and the protrusion block 1041 is in the channel; in the initial state, the safety button 104 is in a locked state, that is, the safety button 104 cannot be pressed, and when the release button 103 is pressed, the safety button 104 is in an open state, at which time the safety button 104 can be pressed, that is, it can be moved laterally. Therefore, it can be ensured that the handle 100 cannot be activated when the cassette box 200 is not installed, thereby avoiding accidental contact by non-operating personnel.

When the cassette 200 is mounted on the handle 100, the cassette 200 presses the release button 103, and the inclined surface 109 causes the safety activation strip 215 to open the safety assembly, and then the knob 210 is rotated to open the locking assembly, and the knob 210 is locked to lock the cassette 200 on the handle 100; at this time, the safety button 104 is pressed again, so that the safety button 104 starts to move laterally.

A card block protrusion is provided at one end of the extension portion 107 of the safety button 104. Please refer to Figure 23. A step hole 1084 is provided on the handle portion 108. The card block protrusion is placed in the step hole 1084. The step hole 1084 is provided with at least four steps. The step hole 1084 corresponds to three opening states of the handle 100 and a locked state of the handle 100. When the handle 100 is in the locked state, the protrusion block 1041 is located in the vertical channel 1031.

Please refer to Figure 20. The transmission assembly includes a pushing block 1042 provided on the insurance button 104, a insurance controller 109 movably mounted on the cover plate 123, and a safety 110 elastically hinged on the handle housing through a spring four 119. The insurance controller 109 is provided with a card slot 111, and the insurance 110 is provided with a card block corresponding to the position of the card slot 111. Therefore, when the insurance button 104 moves laterally, the pushing block 1042 will push the insurance controller 109, and then drive the insurance 110 to rotate around the hinge point, so that the block 112 of the insurance 110 is in active contact with the one-way transmission assembly. The one-way transmission assembly and the one-way force assembly are movably mounted on the cover plate 123 through a fixed shaft. Please refer to Figure 20. 24. A guide rail protrusion 1141 is provided on one surface of the one-way transmission component; when the safety 110 is pushed, the stop block 112 moves along the guide rail protrusion 1141, and the guide rail protrusion 1141 cooperates with the step hole 1084; therefore, when the handle 100 is opened for the first time, the safety 110 moves along the guide rail protrusion 1141, so that the stop block 112 gradually approaches the edge of the one-way transmission component after the next step, and when the handle 100 is opened for the second time, the stop block 112 still gradually approaches the edge of the one-way transmission component, and when the handle 100 is opened for the third time, the stop block 112 reaches the position where the guide rail protrusion 1141 is closest to the edge of the one-way transmission component, and when the handle 100 is pressed for the fourth time, the box 200 is removed and the handle 100 is locked.

It also includes a unidirectional force component stacked on the unidirectional transmission component. The handle portion 108 is connected to the unidirectional transmission component through the unidirectional force component. The unidirectional force component is used to only give unidirectional force to the unidirectional transmission component. Therefore, even if the handle portion 108 can transmit bidirectional force clockwise and counterclockwise, the unidirectional force component will only transmit unidirectional force to the unidirectional transmission component through the transmission connection with the unidirectional force component.

Please focus on Figure 20 and Figure 24-25. The unidirectional force component includes a driving gear 113, and the driving gear 113 is movably mounted on a fixed shaft. At the same time, an elastic portion 1132 is provided on one side of the driving gear 113, and a clamping block 1133 is provided on the elastic portion 1132. A pushing protrusion 1143 is provided on the unidirectional transmission component. The pushing protrusion 1143 cooperates with the clamping block 1133 to only apply force to the unidirectional transmission component in one direction. The unidirectional force component is connected to the handle portion 108 for transmission.

The transmission connection is a meshing transmission. Specifically, a toothed portion 1131 is provided on the other side of the driving gear 113, and a toothed portion 1083 provided on the handle portion 108 meshes with the toothed portion 1131 for transmission. When the handle portion 108 is pressed, the toothed portion 1083 meshes with the toothed portion 1131 for transmission, thereby driving the driving gear 113 to rotate counterclockwise, and then the block 1133 cooperates with the pushing protrusion 1143 to drive the one-way transmission component to start transmission. When the handle portion 108 is fully pressed, the handle portion 108 will bounce open under the action of the torsion spring 118, preparing for the next pressing of the handle portion 108.

Please refer to Figure 27. A guide rail protrusion 1144 is provided on the other side of the one-way transmission component. The guide rail protrusion 1144 is divided into three sections, which respectively push the wire actuation component 2131 and the needle actuation component 2132 of the actuation component 1 213 and the actuation component 2 214.

Please refer to Figures 28-29. A wire sliding member 126 is movably installed on the cover plate 123 through spring five 124. At the same time, a needle sliding member 127 is movably installed on the cover plate 123 through spring six 125. When the cartridge 200 is installed on the handle 100, the wire actuating assembly 2131 is stuck on the wire sliding member 126, and the needle actuating assembly 2132 is stuck on the needle sliding member 127. Please refer to Figures 17 and 30-31. A wheel actuator 122 is movably installed on the handle housing. The rotation of the wheel actuator 122 can drive the implant positioning safety 2145 to disengage from the push rod fixing member 2141.

The three sections of the guide rail protrusion 1144 can respectively drive the needle slider 127 and the thread slider 126 to move, and drive the wheel actuator 122 to rotate. When the handle portion 108 is pressed for the first time, the handle portion 108 drives the one-way transmission assembly to rotate, and then the guide rail protrusion 1144 pushes the needle slider 127 and the thread slider 126 forward, so that the actuating assembly 1 213 drives the clip push rod 207, the puncture needle 203 and the suture thread 202 to move forward at the same time, and the clip push rod 207 simultaneously pushes the front clip 201 forward. At this time, the safety button 104 moves with the guide rail protrusion 1141, and then the handle portion 108 returns to the open state; when the handle portion 108 is pressed for the second time, the handle portion 108 drives the one-way transmission assembly to rotate, Then, the guide rail protrusion 1144 pushes the needle slider 127 and the thread slider 126 backward, so that the actuating assembly 1 213 drives the puncture needle 203 backward, and at the same time drives the suture 202 to be tightened, and drives the front clamp 201 to be unfolded; when the handle part 108 is pressed for the third time, the guide rail protrusion 1144 drives the wheel actuator 122 to rotate, so that the actuating assembly 2 214 drives the push rod 205 and the cutter 206 to move at the same time, the cutter 206 retreats, and the push rod 205 pushes the rear clamp 204 forward, so that the rear clamp 204 clamps the suture 202 and cuts the suture 202 at the same time, and the entire suspensor is pulled out and leaves the treatment state; when the handle part 108 is pressed for the fourth time, the box 200 is removed and the handle 100 is locked.

With the cooperation of the one-way transmission component, the pushing protrusion 1143 and the elastic part 1132, the transmission component can only transmit in one direction, thereby avoiding entering the next operation step or returning to the previous operation step before the surgical operation is complete. It will stop in the incomplete process, and when the handle part 108 is pressed again, it will continue to complete this step until the operation step is completely completed. The next step will not be entered until the handle part 108 is pressed next time, that is, the next action will not be entered before the previous action is completed, thereby avoiding surgical errors.

At the same time, the design of the handle 100 greatly simplifies the surgical operation steps. The handle portion 108 only needs to be pressed four times, and the entire device will automatically perform the entire surgical process. At the same time, the handle 100 can be locked after the operation is completed, which greatly facilitates the operator's work process.

Furthermore, the handle 100 is also provided with a limiting component, which is used to limit the pop-up state of the handle portion 108. When an operation step is not fully completed, the handle portion 108 will not be popped open, but will be limited to the current position.

Please refer to Figures 23 and 26. The limiting assembly includes an arc groove 1085 provided on the handle portion 108, a positioning cam 116 coaxially installed with the safety controller 109, and a positioning cam positioning piece 117 installed on the handle housing. When the handle portion 108 is fully pressed, the end of the positioning cam 116 will be separated from the arc groove 1085 under the action of the positioning cam positioning piece 117, so that the handle portion 108 can be restored to a fully opened state, and when the handle portion 108 is not fully pressed, the end of the positioning cam 116 will stay in the concave groove of the arc groove 1085 and cannot be separated from the concave groove, so that the handle portion 108 cannot be restored to a fully opened state, and the handle portion 108 will stay in the pressed position.

Therefore, with the cooperation of the limiting component and the one-way transmission component, the next action will not be entered before each action is completed, and the handle part 108 will also stay in the pressed position, thereby reminding the operator that the work is not completed.

Please refer to Figures 18 and 24. The handle portion 108 is also provided with a clamping block 1082, which cooperates with the limiting groove 1142 provided on the one-way transmission assembly; when the handle portion 108 is fully pressed, the clamping block 1082 can sink into the limiting groove 1142, and the limiting groove 1142 can limit the pressing degree of the handle portion 108 to avoid excessive pressing of the handle portion 108.

Please focus on Figures 26 and 33-34. The indicator wheel assembly 121 includes a driving wheel 1214 that is coaxially driven with the safety 110, a driving wheel 1213 that is movably mounted on the handle housing, an indicator wheel driving wheel 1211 that is elastically connected to the handle housing through a torsion spring 3, a one-way transmission assembly and a one-way force assembly that are movably mounted on the handle housing through a fixed shaft 2, the indicator wheel driving wheel 1211 is transmission-connected to the one-way transmission assembly through the one-way force assembly, so that the one-way transmission assembly rotates unidirectionally under the drive of the indicator wheel driving wheel 1211, and four numbers are respectively provided on the outer surface of the one-way transmission assembly, representing the first operation step, the second operation step, the third operation step and the locking step, corresponding to the steps of pressing the handle portion 108 four times; the driving wheel 1214 is transmission-connected to the driving wheel 1213, and the driving wheel 1213 is transmission-connected to the indicator wheel driving wheel 1211, and an indicator cover 1215 is covered outside the one-way transmission assembly, and the indicator cover 1215 is mounted on the handle housing.

The driving wheel 1213 is provided with two arm 1s, and the indicating wheel driving wheel 1211 is provided with two arm 2s, the arm 1s are staggered with the arm 2s, and the arm 1s are provided with transmission protrusions, and the driving wheel 1214 will contact with the transmission protrusions when rotating, thereby promoting the rotation of the driving wheel 1213, and because the arm 1s are staggered with the arm 2s, the indicating wheel driving wheel 1211 is driven to rotate, thereby further driving the indicating wheel 1217 to rotate. The driving wheel 1214 rotates with the rotation of the insurance 110, and the insurance 110 rotates due to the pressing of the handle 108, so each time the handle 108 is pressed, the one-way transmission assembly will rotate accordingly, thereby displaying different numbers, indicating the operation step it is in, and then reminding the operator. Since the handle portion 108 will return to the open state each time the handle portion 108 is fully pressed, and in order for the driving wheel 1214 to continue to transmit the transmission to the indicating wheel driving wheel 1211, the indicating wheel driving wheel 1211 is elastically connected to the fixed shaft 2 via a torsion spring 3. Therefore, each time the driving wheel 1214 returns to its original state, the indicating wheel driving wheel 1211 will return to its original state under the action of the torsion spring 3. Since the indicating wheel driving wheel 1211 is connected to the one-way transmission component via a one-way force component, the one-way transmission component remains unchanged when the indicating wheel driving wheel 1211 returns to its original state.

The unidirectional force component includes a driving gear 113, and the driving gear 113 is movably mounted on the fixed shaft one or the fixed shaft two. At the same time, an elastic portion 1132 is provided on one side of the driving gear 113, and a clamping block 1133 is provided on the elastic portion 1132. A pushing protrusion 1143 is provided on the unidirectional transmission component. The pushing protrusion 1143 cooperates with the clamping block 1133 to only apply force to the unidirectional transmission component in one direction. The unidirectional force component is connected to the indicator wheel driving wheel 1211 for transmission.

The transmission connection is a meshing transmission. Specifically, a toothed portion 1131 is provided on the other side of the driving gear 113, and a toothed portion 1083 provided on the indicating wheel driving wheel 1211 is meshed with the toothed portion 1131 for transmission. When the indicating wheel driving wheel 1211 rotates, the toothed portion 1083 is meshed with the toothed portion 1131 for transmission, thereby driving the driving gear 113 to rotate counterclockwise, and then the block 1133 cooperates with the protrusion 1143 to push open and drive the one-way transmission component to start transmission.

Specifically, please focus on Figure 19. The one-way transmission assembly includes a wheel, which is provided with a ratchet tooth protrusion or groove, and a positioning piece 115. The wheel is a cam 114 or an indicator wheel 1217. The positioning piece 115 is installed on the handle housing and the indicator cover 1215. One end of the positioning piece 115 fits with one of the ratchet teeth, so that the cam 114 and the indicator wheel 1217 can only rotate in one direction.

The outer arc designs of the push-open protrusion 1143 on the cam 114 and the push-open protrusion 1143 on the indicator wheel 1217 are different, but their functions are the same, both of which are to cooperate with the driving gear 113 to give a unidirectional force to the one-way transmission component. The push-open protrusion 1143 on the cam 114 needs to cooperate with the three-section guide rail of the guide rail protrusion 1144, so as to ensure that when the handle 100 is started four times, the corresponding operating steps can be performed respectively.

First, the design of the handle locking device in the handle 100 can ensure the locking state of the handle 100, and the handle 100 will not be opened before the corresponding opening action is performed, thereby improving the safety of the locked state; the coordinated design of the limiting component, the one-way transmission component and the one-way force component in the handle 100 can prevent the next action from being entered before each action is completed, and the handle part 108 will also stay in the pressed position, thereby reminding the operator that the operation is not completed and avoiding surgical errors; at the same time, the design of the identification component and the indicator wheel component 121 in the handle 100 can display the specific operating status during the operation, improve the operator's understanding of the operating steps of the device, and facilitate the operator's subsequent operations and handling of emergencies.

Based on the above device, the first embodiment of the present invention further proposes an operation method using the above-mentioned hanger, comprising the following steps:

Step 1: Install the box 200 on the handle 100, lock the box 200 with the safety assembly and the locking assembly, and open the handle locking device at the same time. Then, when the handle 108 is pressed for the first time, the indicator wheel assembly 121 displays the number of the first operation step, and the handle 108 drives the one-way transmission assembly to rotate, so that the actuating assembly 1 213 drives the clip push rod 207, the puncture needle 203 and the suture 202 to move forward at the same time, and the clip push rod 207 simultaneously pushes the front clip 201 forward. After the first operation step is completed, the handle 108 returns to the open state.

Step 2: Press the handle 108 for the second time, the indicator wheel assembly 121 displays the number of the second operation step, the handle 108 drives the one-way transmission assembly to rotate, and then pushes the needle slider 127 and the thread slider 126 to retreat, so that the actuating assembly 1 213 drives the puncture needle 203 to retreat, and at the same time drives the suture 202 to tighten, and drives the front clip 201 to unfold. After the entire second operation step is completed, the handle 108 returns to the open state;

Step 3: Press the handle 108 for the third time, the indicator wheel assembly 121 is displayed as the number of the third operation step, the handle 108 drives the one-way transmission assembly to rotate, and then drives the wheel actuator 122 to rotate, so that the actuating assembly 214 drives the push rod 205 and the cutter 206 to move simultaneously, the cutter 206 moves backward, and the push rod 205 pushes the rear clamp 204 forward, so that the rear clamp 204 clamps the suture 202 and cuts the suture 202 at the same time;

Step 4: After the handle 108 is pressed for the fourth time, the indicator wheel assembly 121 displays the number of the locking step, and then the cassette 200 is removed and the handle 100 is locked.

The design of the suspension greatly simplifies the surgical operation steps. The handle 100 only needs to be opened four times, and the entire device will automatically perform the entire surgical process. At the same time, the handle 100 can be locked after the operation is completed, which greatly facilitates the operator's work process.

The unidirectional force component includes a driving gear 113, and the driving gear 113 is movably mounted on the fixed shaft one or the fixed shaft two. At the same time, an elastic portion 1132 is provided on one side of the driving gear 113, and a clamping block 1133 is provided on the elastic portion 1132. A pushing protrusion 1143 is provided on the unidirectional transmission component. The pushing protrusion 1143 cooperates with the clamping block 1133 to only apply force to the unidirectional transmission component in one direction. The fixed shaft one coincides with the hinge hole 1081, and the unidirectional force component is coaxially connected with the indicator wheel driving wheel 1211 and the handle portion 108.

Embodiment 3

The one-way transmission component described in Example 1 is a one-way transmission achieved by using spring pieces and ratchet teeth. The one-way transmission component of this embodiment is a one-way transmission achieved by using two overlapping ratchet teeth. This one-way transmission component includes ratchet tooth one provided on the indicating wheel 1217 or the cam 114, and ratchet tooth two placed in the indicating wheel 1217 or the cam 114. The ratchet tooth two is elastically connected to the fixed shaft one or the fixed shaft two through a compression spring 1216. At the same time, a limiting protrusion 1212 is provided on the ratchet tooth two, and the limiting protrusion 1212 is matched with the guide rail of the fixed shaft one or the fixed shaft two, so that under the cooperation of the ratchet tooth one and the ratchet tooth two, the indicating wheel 1217 or the cam 114 can only rotate in one direction. At the same time, when the indicating wheel 1217 or the cam 114 only rotates, the ratchet tooth two will move up and down along the track.

Embodiment 4

The hanger disclosed in the fourth embodiment is different from the first embodiment in that the other devices, installation positions and operation methods thereof are the same as those in the first embodiment except for the clamping assembly 209 .

The clamping assembly 209 includes a folding portion provided on the folding component itself, which makes the folding portion elastic, and a limiting portion provided on the folding portion, which can further limit the left-right movement of the workpiece.

Embodiment 5

As shown in FIGS. 36-38 , the suspension device disclosed in the fifth embodiment includes a mirror lock assembly 120 , and other devices and their installation positions and operation methods are the same as those in the first embodiment.

In the prior art, the cartridge 200 is generally installed on the handle 100 before the endoscope is inserted into the cartridge 200. In order to facilitate the operator to observe the position of the tip of the cartridge 200 after inserting the hanger, and in order to lock the endoscope in the cartridge 200, a scope lock assembly 120 is designed.

The mirror lock assembly 120 includes a mirror lock handle 1201 installed on the handle housing, and a mirror lock sleeve 1202 stuck in the mirror lock handle 1201, and a locking sleeve 1203 is symmetrically provided on the center of the mirror lock sleeve 1202, and one end of the locking sleeve 1203 is separated from the mirror lock sleeve 1202 and gradually approaches the axis of the mirror lock sleeve 1202.

Therefore, when the endoscope is inserted into the scope tube channel bracket 2084, the end of the endoscope is screwed onto the handle housing. Due to the design of the locking sleeve 1203, when the endoscope is inserted, the endoscope will contact one end of the locking sleeve 1203, so that when the endoscope rotates, the locking sleeve 1203 will be driven to move accordingly, so that the two locking sleeves 1203 rotate and lock the endoscope as the endoscope rotates, thereby achieving the purpose of locking the endoscope in the box 200.

Embodiment 6

As shown in FIGS. 39-41 , the hanger disclosed in the sixth embodiment includes a locking block 300 , and other devices and their installation positions and operation methods are the same as those in the first embodiment.

The locking block 300 is provided with a locking protrusion 1 301 and a handle end 304. The design of the handle end 304 facilitates the staff to rotate the locking block 300. The locking protrusion 2 302 on the locking block 300 is provided through the connecting block 306, and the cover plate 123 is provided with a locking guide rail 303 corresponding to the locking protrusion 1 301. Therefore, when the handle end 304 is rotated, the locking protrusion 1 301 rotates along the locking guide rail 303, and at the same time, the locking protrusion 2 302 rotates in the gap between the cover plate 123 and the handle shell, and the position of one end of the locking protrusion 2 302 exceeds the end position of the connecting block 306. Therefore, when the locking block 300 is rotated to a vertical state, the limiting plate 305 provided on the handle shell can limit the movement of the connecting block 306, and at this time, the locking protrusion 2 302 is stuck between the limiting plate 305 and the cover plate 123, thereby preventing the locking block 300 from falling off the handle 100.

At this time, the matching design of the locking protrusion 1 301 , the locking protrusion 2 302 and the locking guide rail 303 limits the locking block 300 to only be able to perform a rotation operation, and the design of the limiting plate 305 limits the rotation limit of the locking block 300 .

When the locking block 300 rotates to the horizontal state, the clamping block 307 provided on the locking block 300 forms a secondary locking state with the clamping matching blocks 308 provided on the box 200 and the handle 100 respectively.
