Thus, reference throughout this specification to one feature will be used in order to describe one embodiment of the invention, not to imply that each embodiment of the invention must be in the proper motion. Furthermore, it should be noted that the present specification describes a number of features. Although certain features may be combined together to illustrate a possible system design, such features may be used in other combinations not explicitly described. Thus, unless otherwise indicated, the illustrated combinations are not intended to be limiting.
In the embodiment shown in the drawings, indications of orientation (such as up, down, left, right, front and rear) are used to explain the structure and movement of the various elements of the invention are not absolute but relative. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the description of the position of these elements changes, the indication of these directions changes accordingly.
Preferred embodiments of the present invention will be further elaborated below with reference to the drawings of the present specification.
The invention provides a disposable endoscope. Such a disposable endoscope is compared to a conventional endoscope, conventional endoscopes are reusable. After the initial use, the conventional endoscope needs to be sterilized intensively for the next use. Because the endoscope has smaller volume and more corners and slits, the endoscope cannot be completely disinfected, and therefore, the conventional endoscope is used repeatedly, so that the risk of cross infection exists. The disposable endoscope of the present embodiment disposes the contaminated portion to avoid reuse.
Referring to fig. 1 and 2, the disposable endoscope of the present embodiment includes a handle 10 and an insertion portion 20 of the disposable endoscope. Because the insertion part is polluted during use, the disposable endoscope is discarded at the part with the insertion part after being used, so that the sanitation degree of the endoscope can be improved, and the safe use of patients can be ensured. And the discarded part is removed, the rest part is not polluted, the recycling can be realized, and the cost is saved.
The insertion part 20 is used to enter the body cavity, and the insertion part 20 can gradually enter the affected part along with the bending of the body cavity. Referring to fig. 2, the insertion portion 20 of the disposable endoscope includes an insertion tube 21, a bending portion, a traction wire 23, and a head end 24. The insertion tube 21 is sleeved outside the bending portion, and the head end 24 is positioned at the foremost end of the bending portion. The traction wire 23 is connected to the bending portion, and the movement of the traction wire 23 can operate the bending direction of the bending portion to control the operations such as advancing and bending.
Referring to fig. 2, a handle 10 of a disposable endoscope includes a first structure 11 and a second structure 12 drivingly connected to each other. The first structure 11 includes a driving portion 13. The driving part 13 is used for driving and adjusting the bending angle of the insertion part 20, and the second structure 12 is used for being connected with the insertion part 20.
Referring to fig. 3, the first structure 11 is provided with a first joint 111, and the second structure 12 is provided with a second joint 121. The first connector 111 is detachably connected to the second connector 121. In preparation for use of the disposable endoscope, the handle 10 of the disposable endoscope is assembled by abutting the first joint 111 and the second joint 121 against each other. When the disposable endoscope is used, it is detached from the second joint 121 by the first joint 111 to separate the first structure 11 from the second structure 12.
Referring to fig. 2, therefore, after the handle 10 of the disposable endoscope of the present embodiment is used, since the second structure 12 connected to the insertion portion 20 is separable from the first structure 11, the second structure 12 is discarded along with the insertion portion 20, and the first structure 11 is left uncontaminated. Therefore, the first structure 11 is not polluted, can be reused, and reduces the use cost. In addition, the second structure 12 and the insertion portion 20 are used for the first time, so that the sanitation standard of the disposable endoscope can be ensured, and the safety of using the endoscope can be improved.
Referring to fig. 3, in the present embodiment, the driving portion 13 includes a first gear 131 and a first rack 132. The first gear 131 is meshed with one end of the first rack 132, and the first rack 132 is driven to stretch and retract by rotating the first gear 131.

The plurality of rotating wheels 133 are coaxially disposed up and down. The rotating wheel 133 is connected to the bending portion 22 through the traction wire 23, and the rotating wheel 133 rotates to drive the traction wire 23 to move, thereby operating the bending direction of the bending portion 22.
In particular, in the present embodiment, the rotating wheel 133 includes a first rotating wheel 134 and a second rotating wheel 135. The first rotating wheel 134 and the second rotating wheel 135 respectively drive the two first gears 131. The first gear 131 rotates forward and backward on the first rack 132, thereby driving the first rack 132 to move telescopically. Among them, one of the two first gears 131 is used to adjust the bending angle of the insertion portion 20 in the left-right direction, and the other first gear 131 is used to adjust the bending angle of the insertion portion 20 in the up-down direction.
It will be appreciated that turning the first turning wheel 134 can adjust the bending angle of the insertion portion 20 in the left-right direction. Turning the second turning wheel 135 can adjust the bending angle of the insertion portion 20 in the up-down direction. Therefore, the first rotating wheel 134 and the second rotating wheel 135 can respectively adjust the rotation of the corresponding first gear 131 to drive the corresponding first rack 132 to stretch and retract. The control directions of the first rotating wheel 134 and the second rotating wheel 135 are not limited herein, as long as the first rotating wheel 134 and the second rotating wheel 135 cooperate with each other to control the bending angle of the bending.
Please refer to fig. 3, in particular, in the present embodiment. The first joint 111 is disposed at an end of the first rack 132 remote from the first gear 131. The number of first racks 132 is two, and the number of first joints 111 is also two.

Therefore, when the rotating wheel 133 is rotated, the adjustment operation is transmitted to the wire 23 through the transmission connection between the first rack 132 and the second rack 123, thereby achieving the purpose of adjusting the bending angle of the insertion portion 20.
In particular, in the present embodiment, the second structure 12 includes a plurality of second gears 122 and a plurality of second racks 123. Specifically, the number of the first racks 132 is two, the number of the second racks 123 is four, and the four second racks 123 are rectangular in distribution. Since the bending direction of the insertion portion 20 is four. The insertion portion 20 includes four traction wires 23. The traction wire 23 is used to drive the head end 24 of the traction section to adjust bending in four directions. Each traction wire 23 is in driving connection with a second rack 123, respectively. The second rack 123 moves to drive the traction wire 23 to move.
In other embodiments, the number of the first racks 132 and the second racks 123 may be other than two. Accordingly, the adjusting direction of the insertion portion 20 may be a plurality of angles, which is not limited herein.
For convenience of description, two second racks 123 and a second gear 122 are now divided into one group. The four second gears 122 are divided into two groups. The teeth of the second racks 123 in the same group are disposed opposite to each other, and opposite sides of a second gear 122 are separated to be engaged with both sides of the second gear 122. Each set of second racks 123 corresponds to one first gear 131 and one first rack 132, and adjustment of the first gear 131 to the bending direction of the insertion portion 20 is achieved.
The second rack 123 in the same group includes a second driving rack 1231 and a second driven rack 1232. Wherein the second driving rack 1231 and the second driven rack 1232 of the same group are engaged with the same second gear 122. The second joint 121 is disposed at one end of the second driving rack 1231, and the second driving rack 1231 and the first rack 132 are in driving connection through the first joint 111 and the second joint 121. The second driving rack 1231 is pushed by the first rack 132 to stretch and retract, so that the second gear 122 rotates and drives the second driven rack 1232 to stretch and retract.
For two second racks 123 located in the same group, only one of the first racks 132 is in opposite butt joint with one of the second driving racks 1231, and the detachable connection is realized, so that the driving of the two second racks 123 can be realized. Therefore, the second driven racks 1232 perform driving motion through the second gear 122, so that the number of the first racks 132 can be reduced, the difficulty in butt joint between the first racks 132 and the second racks 123 can be reduced, and the integral separable arrangement of the first structure 11 and the second structure 12 can be realized.
And, the second joint 121 is located at one end of the second driving rack 1231 near the first rack 132. The second connector 121 is engaged with the first connector 111.
Referring to fig. 5 and 6, specifically, the first joint 111 includes an arc-shaped boss 1111 and a rotating shaft 1112. The arc-shaped projection 1111 is provided with an arc-shaped outer surface. The rotary shaft 1112 is disposed at one end of the arcuate projection 1111. The second connector 121 is provided with a clamping groove 124 for accommodating the arc-shaped protruding head 1111, and the clamping groove 124 is in clamping connection with the arc-shaped protruding head 1111 of the first connector 111. The end of the second joint 121 is provided with a shaft hole for accommodating the rotary shaft 1112. Further, the arc-shaped protruding head 1111 is rotatably accommodated in the clamping groove 124, and the rotating shaft 1112 is rotatably accommodated in the shaft hole.
The second connector 121 is provided with a guide portion 125 on one side of the locking groove 124, and the guide portion 125 extends from one side of the second connector 121 into the locking groove 124. When the second connector 121 is aligned with the first connector 111, the first connector 111 and the second connector 121 rotate relatively by rotating the first structure 11 or the second structure 12, so that the circular arc outer surface of the arc-shaped protruding head 1111 slides smoothly into the clamping groove 124 along the guiding portion 125 and is in clamping connection with the clamping groove 124. Specifically, the guide 125 is a smooth arcuate surface.
The first structure 11 or the second structure 12 is reversed, the first joint 111 and the second joint 121 are rotated relatively, the arc-shaped protruding head 1111 is separated from the clamping groove 124, the rotating shaft 1112 is separated from the shaft hole, and the first joint 111 and the second joint 121 are separated, so that the first structure 11 and the second structure 12 can be separated.
Referring to fig. 7 and 8, in this embodiment, the first structure 11 further includes an alignment tab 112. The alignment tab 112 is located at a central location of the plurality of first tabs 111. The second structure 12 is provided with alignment features 126. The alignment structure 126 is also centered on the plurality of second joints 121. After the alignment structure 126 and the alignment tab 112 are aligned with each other, it represents that the first structure 11 and the second structure 12 are aligned with each other to assist the first tab 111 and the second tab 121 in abutting each other.
Specifically, in the present embodiment, the alignment tab 112 is a protrusion, and the alignment structure 126 is a recess for receiving the protrusion. The alignment structure 126 is located at the center of the four second gears 122 distributed in rectangular shape, and the alignment joint 112 is correspondingly located at the middle position of the two first joints 111, and is matched and inserted with the alignment structure 126.
Referring to fig. 5 and fig. 6, the arc-shaped protrusion 1111 of the first connector 111 rotates at the opening of the clamping groove 124 of the second connector 121, i.e. the arc-shaped protrusion 1111 is clamped into the clamping groove 124, so as to realize the clamping connection between the first connector 111 and the second connector 121. The openings of the clamping grooves 124 of the two second connectors 121 are mutually staggered. When the arc-shaped protruding head 1111 is placed at the opening of the clamping groove 124, the alignment joint 112 is prevented from interfering with the arrangement of the arc-shaped protruding head 1111, so that the first joint 111 and the second joint 121 are prevented from being butted with each other.
In other embodiments, the first connector 111 and the second connector 121 may be connected in a butt joint and a detachable manner by magnetic attraction, screwing, or the like.
Referring to fig. 9, since the head end 24 of the insertion portion 20 is provided with the image acquisition module 25. The image acquisition module 25 acquires image signals in the internal body cavity. The disposable endoscope needs to send the image signal to a host computer, which can complete the final processing of the image signal.
In particular, in the present embodiment, the first structure 11 further includes a first circuit 117. The second structure 12 further includes a second circuit 127. The second circuit 127 is electrically connected to the image acquisition module 25 for propagating the image signal.
The first circuit 117 is provided with a first port 1171 and the second circuit 127 is provided with a second port 1271. The first connector 111 interfaces with the second connector 121 and the first port 1171 is electrically connected with the second port 1271. The image signal is sent to the first circuit 117 via the second circuit 127.
The first circuit 117 includes a digital signal processing line 1172. The image signals are transferred to the digital signal processing circuit 1172 through the first port 1171 and the second port 1271. The digital signal processing circuit 1172 can perform processing of the image signal such as compression data amount, amplification signal strength, and the like. It is understood that the digital signal processing circuitry 1172 may be an image processing chip or a position location chip, etc.
Typically, disposable endoscopes require electrical connection to the host computer via a longer wire 30 to transmit image signals to the host computer. However, since the image signal is inconvenient for remote transmission, if the image signal is directly transmitted to the host, the image signal may generate large noise, which affects the accuracy of the image signal. Therefore, the disposable endoscope of the present embodiment needs to be enlarged by the image processing circuit and then transferred. The image processing circuit is arranged in the handle 10, so that the problem of signal transmission distance can be solved, and the image signal amplified by the image processing circuit can be accurately transmitted to the host computer for signal processing.
One end of the first circuit 117 far away from the second circuit 127 is used for being connected with a host, so that the image acquisition module 25 is electrically connected with the host through the first circuit 117 and the second circuit 127. The image signal may be processed by the digital signal processing circuitry 1172 and then conducted to the host, which may complete the final processing of the image signal. The handle 10 of the disposable endoscope can realize the detachable connection of the first structure 11 and the second structure 12, and can also realize the electric connection of the first circuit 117 and the second circuit 127 through the first port 1171 and the second port 1271, so as to ensure that the image signal can be transmitted to the host for signal processing.
And, when the first structure 11 and the second structure 12 are detached from each other, the first structure 11 is detached from the handle 10. In the use process of the disposable endoscope, only the second structure 12 of the handle 10 is polluted, so that only the second structure 12 of the handle 10 is needed to be discarded, the first structure 11 can be kept for reuse, the first structure 11 is prevented from being discarded along with the insertion part 20, the resource waste is avoided, and the use cost is saved. In addition, the first circuit 117 is also retained along with the first structure 11, so that the digital signal processing circuit 1172 can also be retained, further avoiding the waste of resources and further saving the use cost of the disposable endoscope.
In particular, in this embodiment, the first structure 11 further includes a first housing 118, and the second structure 12 further includes a second housing 128. The first housing 118 defines a first receiving cavity. The first accommodating cavity is used for accommodating components such as the first connector 111, the first circuit 117 and the like. The second housing 128 defines a second receiving cavity. The second accommodating cavity is used for accommodating components such as the second connector 121, the second circuit 127 and the like.
The first housing 118 and the second housing 128 are detachably connected. The handle 10 of the disposable endoscope formed by the first housing 118 and the second housing 128 being joined to one another provides a generally contoured configuration for providing a load bearing function. The first housing 118 and the second housing 128 are injection molded.
Specifically, in the present embodiment, the first housing 118 and the second housing 128 are engaged with each other. The first casing 118 and the second casing 128 are provided with hooks 119 or buckles, etc., which cooperate with each other to realize a snap connection.
Therefore, in the disposable endoscope in the above embodiment, when the operation of using the endoscope is completed, since the first structure 11 portion of the handle 10 does not enter the human body and is not contaminated, there is no risk that the first structure 11 of the handle 10 is reused and mutual infection occurs between patients due to the reuse of the first structure 11. Therefore, the disposable endoscope can ensure safe use, and simultaneously can reduce the discarded waste elements as much as possible, thereby saving the cost.
And, the first joint 111 of the first structure 11 and the second joint 121 of the second structure 12 cooperate with each other to realize detachable connection. When the first joint 111 and the second joint 121 are mutually butted, the structural design of the aligning joint 112 and the guide part 125 greatly reduces the aligning difficulty of the first joint 111 and the second joint 121, and the butt joint and locking can be realized by rotation, so that the operation is convenient.
