Tympanic membrane puncture is a commonly used clinical operation for the diagnosis and treatment of middle ear diseases. It can be used for puncture and aspiration of secretory otitis media, middle ear effusion, and severe negative pressure in the middle ear caused by Eustachian tube dysfunction. It is also possible to inject medicine into the middle ear through tympanic membrane puncture to treat some middle ear and inner ear diseases. Tympanic membrane puncture is a routine operation, and the specific operation can usually be performed in an outpatient clinic.

The current traditional treatment method is to use a device similar to a syringe. After the needle puncture operation is completed, the syringe is used to aspirate out the fluid. However, if the amount of fluid required in this method is too large and cannot be extracted at one time, the patient will be If the operation is performed multiple times, it will create a greater fear of treatment in the patient, and it will also affect the quality of treatment and cause secondary harm to the patient. Therefore, it is impossible to puncture the same hole multiple times, which means that multiple holes need to be punctured. position, and because the puncture needle pierces the tympanic membrane straightly, it is located in the tympanum when extracting liquid, and the tympanum is arc-shaped and the puncture needle is in a straight state, it is impossible to extract liquid lower than the puncture needle, and the medical staff inserts the needle straight During the puncture process, it is easy for the needle to shake due to shaking hands and cause damage to the patient's ear, which will directly affect the treatment process. During the tympanic membrane puncture to extract the liquid, if there is too much dirt, it is difficult to remove. It is easy for the puncture needle to penetrate straight into the tympanic membrane during the puncture process. Causes blockage at the needle and affects the suction operation. When the puncture needle is inserted into the tympanic cavity to absorb the fluid accumulation, the puncture needle enters straight. When the fluid accumulation level inside the tympanic cavity is lower than the suction port of the puncture needle, more suction is required. The force will become greater, thus causing pain and the risk of secondary injury, so this device provides a visual tympanic membrane puncture needle and its use method.

A method for using a visual tympanic membrane puncture needle includes the following steps:

S1: First, before puncture treatment, remove the dirt inside the patient’s ears according to the dirt condition of the patient’s ears;

S2: Then set the ear external fixing piece on the outside of the ear, and install the ear clip to the sleeve. The sleeve is connected to the ear external fixing piece and extends into the ear;

S3: Then pass the fixed tube through the ear clip, and the sleeve is located at the side of the tympanic membrane inside the ear. Pass the puncture needle through the fixed tube, the ear clip, and the sleeve is located at the side of the tympanic membrane inside the ear;

S4: Then push the ear clip to the inside of the connecting tube, unfold the two supporting arc-shaped parts to form a support and fixation inside the ear, which can provide a good working environment through external and internal fixation. Continue to push the ear clip, and the fixed tube will be squeezed. Pressed to form a clamped limit state;

S5: At this time, the puncture needle slowly moves toward the tympanic membrane in the fixed barrel and punctures the tympanic membrane. After the puncture is completed, the puncture needle returns to the original route and the puncture needle is taken out;

S6: Then pass the required effusion suction tube through the fixed tube, ear clip, and sleeve at the side end of the tympanic membrane inside the ear in a puncture needle movement, and extend into the tympanum, so that the liquid can be extracted;

S7: After the effusion suction tube is extended, the head end of the effusion suction tube is located at the effusion inside the tympanic cavity. The head end of the effusion suction tube has a slight bend and is close to the bottom of the effusion inside the tympanic cavity. At this time, you only need to connect the end of the effusion suction tube to the required extraction equipment to achieve maximum extraction of the effusion.

At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

First, in this device, after the fixed cylinder is clamped to the limit, the medical staff will first pass the puncture needle through the fixed cylinder. Through the route of the fixed cylinder, the puncture needle will move to the side of the tympanic membrane and puncture the tympanic membrane. When the puncture needle passes through the After the needle punctures the tympanic membrane, return the puncture needle to the original route and withdraw it from the fixed cylinder. Then, pass the first end of the effusion suction tube to be used to extract the fluid through the fixed cylinder in the same way as the puncture needle and until to the effusion inside the tympanic cavity, and the head end of the effusion suction tube has a slight bend. Therefore, when the head end of the effusion suction tube is located at the effusion inside the tympanic cavity, it is at the closest point to the effusion inside the tympanic cavity. At the bottom, at this time, you only need to connect the end of the effusion suction tube to the required extraction equipment to achieve maximum extraction of effusion. After the extraction equipment is started, the effusion inside the tympanic cavity can be extracted. Through this method of the present invention, This method of extracting effusion can maximize the extraction of effusion inside the tympanic cavity, facilitate patients to obtain better treatment effects, and provide medical staff with more convenient operation and treatment. It will not cause the puncture needle to puncture in the existing technology. Directly entering the tympanic membrane can easily cause blockage at the needle and affect the suction operation. When the puncture needle is inserted inside the tympanic cavity to absorb the accumulated fluid, the puncture needle enters straight, which carries certain risks and can easily cause internal injuries to the patient's ear. When the level of fluid accumulation inside the tympanic cavity is lower than the suction port of the puncture needle, the suction force required will become larger, thus causing pain to the patient and the risk of secondary injury.

Secondly, when this device performs tympanic membrane puncture treatment on the patient, it first sets the external ear sleeve on the outside of the patient's ear to be treated, and then extends the sleeve into the ear. The present invention is a whole after the splicing is completed, and through the two camera probes on the sleeve and the connecting body, the sleeve and the connecting sleeve reach the designated position inside the ear, and the connecting sleeve on the outside of the ear is connected to the sleeve. The outside is snap-connected to form a support point. At this time, the fixed barrel, puncture needle and effusion suction tube do not pass through the ear forceps, sleeve and connecting barrel. At this time, the first end of the fixed barrel is threaded through in turn. After passing through the fixed hole, sleeve and connecting tube at the end of the ear forceps, the medical staff accurately viewed through the camera probe and moved the head end of the fixed tube to the side of the tympanic membrane inside the patient's ear so that it was almost in contact, and then pushed the ear forceps. The end makes the head end of the ear tweezers pass through the head end of the sleeve and move toward the inside of the connecting tube. After the head end of the ear tweezers is located inside the connecting tube and comes into contact with the two support plates, it continues to push the end of the ear tweezers to move, while the two supports Due to the slope, the plate will change the lateral force of the ear tweezers into a vertical force to move the two support plates symmetrically. The two support blocks are located in the sliding groove and are in a sliding fit state, thus driving the two support arcs. The shaped parts are expected to be symmetrically deployed to form a support point inside the ear. The present invention has a support point both outside the ear and inside the ear. Therefore, during the puncture treatment process, no injuries will be caused due to operator errors caused by trembling hands of medical staff. Risk of puncture treatment failure and secondary injury to the patient.

Third, after the head end of the ear tweezers is located inside the connecting tube, according to the different inner diameters of the connecting tube and the sleeve, the head ends of the ear tweezers will move inward during the movement inside the connecting tube, and will move inward between the two support arcs. When the shaped piece collides with the inside of the ear to form a supporting state, the head end of the ear forceps is also in a state of tightly clamping the fixed barrel, thereby ensuring that the subsequent puncture needle and effusion suction tube are not affected when passing through the fixed barrel. It is easy to operate. At the same time, medical staff will not risk puncture treatment failure or secondary injury to the patient due to operational errors. The clamped fixed barrel forms a stable puncture route inside the patient's ear, thereby improving puncture treatment. quality, and provide more convenient operation and treatment methods for medical staff.

Fourth, because excessive dirt inside the ear will affect puncture treatment, the dirt inside the patient's ear needs to be removed before puncture treatment. When removing dirt inside the patient's ear, the medical staff first inserts the sleeve into the patient's ear. , at this time, the connecting sleeve is not connected to the sleeve, and then push the ear tweezers inside the sleeve through the tapered position of the first end of the sleeve. At this time, the first ends of the ear tweezers are closed and pass through the camera probe on the sleeve. It can check the specific distribution of dirt inside the ear. After the medical staff can visually observe the location of the dirt that needs to be removed, the medical staff will move the head end of the ear tweezers from the sleeve to the location where the dirt needs to be removed. , just push the push block to move toward the head end of the ear tweezers on the two push grooves, so that the push block contacts the two sliding blocks, and while the inclined surfaces of the two sliding blocks are squeezed transversely by the push block, The two sliding blocks will symmetrically move closer to their respective directions, and since the ear tweezers have a certain degree of toughness and elasticity, the two ends of the ear tweezers will also symmetrically move closer to their respective directions to achieve a clamping effect. The dirt can be clamped at the dirt removal position of the end movement, and the dirt can be removed by taking out the sleeve. In this way, the dirt can be taken out one by one without affecting the puncture treatment.

One end of the ear clip 2 extends into the interior of the sleeve 1. The fixed barrel 3 passes through the ear clip 2, the sleeve 1 and the connecting barrel 4. The puncture needle 5 passes through the fixed Barrel 3, ear clip 2, sleeve 1 and connecting barrel 4. The effusion suction tube 6 can be used when the puncture needle 5 does not pass through the fixed barrel 3, ear clip 2, sleeve 1 and connecting barrel 4. Through the fixed sleeve 3, the ear clip 2, the sleeve 1 and the connecting sleeve 4, the head ends of the sleeve 1 and the connecting sleeve 4 are both equipped with camera probes 11. Through this method of the present invention, the effusion can be extracted. It can maximize the extraction of fluid inside the tympanic cavity, facilitate patients to obtain better therapeutic effects, and provide more convenient operation and treatment for medical staff. It is different from the existing technology because it is easy for the puncture needle 5 to penetrate straight into the tympanic membrane during puncture. Causes blockage at the needle and affects the suction operation. When the puncture needle 5 is positioned inside the tympanic cavity to absorb the accumulated fluid, the puncture needle 5 enters straightly. There is a certain risk when entering, and it is easy to cause internal injuries to the patient's ears. When the inside of the tympanic cavity is When the level of fluid accumulation is lower than the suction port of the puncture needle 5, the required suction force will become larger, thus causing pain to the patient and the risk of secondary injury;

In the present invention, the sleeve 1, ear clip 2, fixed barrel 3, connecting barrel 4, puncture needle 5 and effusion suction tube 6 are all spliced together and each component can be disassembled separately. On the basis of the necessary functions, another effect can be achieved after the splicing is completed, and the splicing method of each component is relatively convenient. After the use of the present invention is completed, the components can be disassembled one by one to facilitate subsequent disinfection and cleaning operations. One-time preparation for puncture treatment avoids cross-infection during treatment and use between patients. The sleeve 1 itself can be extended into the ear through the sleeve 1 and the specific conditions inside the patient's ear can be observed through the camera sleeve 1. The ear clip 2 itself can be used to remove dirt and can be used in conjunction with the sleeve 1. The puncture needle 5 itself can be used for puncture operations, but there will be certain safety risks when medical staff hold the puncture needle for treatment operations.

Specifically, the sleeve 1 is symmetrically provided with two push grooves 12, and the sleeve 1 is also provided with two sliding grooves 13 which are symmetrically arranged. The ear clip 2 includes ear tweezers 21 and a sliding block 22. and push block 23. The ear tweezers 21 are in the shape of traditional tweezers and have the same function as tweezers. The head ends of the ear tweezers 21 are arranged in an oval shape. There are two sliding blocks 22, and two sliding blocks 22 are provided. The blocks 22 are respectively arranged on both sides of the ear tweezers 21 and pass through the corresponding sliding grooves 13 to be in sliding fit with the corresponding sliding grooves 13. The upper and lower sides of the push block 23 are respectively located on the corresponding pushing grooves 12. The upper and lower sides of the push block 23 are connected to the corresponding push slot 12 in the same principle and structure as a traditional flashlight with the push gear located in the slot. The upper ends of the two sliding blocks 22 are both inclined and close to the push block. One end of 23 is the lowest point, and the end of the ear tweezers 21 is provided with a fixing hole 211. The inner diameter of the fixing hole 211 matches the outer diameter of the fixing cylinder 3 to facilitate the passage of the fixing cylinder 3;

Since excessive dirt inside the ear will affect puncture treatment, the dirt inside the patient's ear needs to be removed before puncture treatment. When removing dirt inside the patient's ear, the medical staff first inserts the sleeve 1 into the patient's ear. When the connecting tube 4 is not connected to the sleeve 1, push the ear tweezers 21 inside the sleeve 1 through the tapered position of the first end of the sleeve 1. Refer to Figure 7. At this time, the first ends of the ear tweezers 21 are closed. Some, and the specific distribution of dirt inside the ear can be viewed through the camera probe 11 on the sleeve 1. After the medical staff visually observes the location of the dirt to be removed, the medical staff moves the sleeve 1 to the ear tweezers. The head end of 21 moves to the position where dirt needs to be removed. At this time, it is only necessary to push the push block 23 on the two push grooves 12 to move in the direction of the head end of the ear tweezers 21, so that after the push block 23 contacts the two sliding blocks 22, And when the inclined surfaces of the two sliding blocks 22 are squeezed laterally by the push block 23, the two sliding blocks 22 will symmetrically move closer to their respective directions. Since the ear forceps 21 have a certain toughness and elasticity, the head of the ear forceps 21 will The two ends will also symmetrically move closer to their respective directions to achieve a clamping effect, so that when the head end of the ear tweezers 21 is moved to the dirt removal position, the dirt can be clamped, and the sleeve 1 can be removed Remove the dirt and remove the dirt one by one through the above method to the extent that it does not affect the puncture treatment;

Since the ear forceps 21 cannot be clamped by squeezing the ear forceps 21 after they are inserted into the ear in the sleeve 1 and the strength may be limited, two sliding blocks 22 and a push block 23 are provided, and The sleeve 1 is provided with two push grooves 12 and two sliding grooves 13 to cooperate to realize the head-end clamping operation of the ear tweezers 21;

When the ear tweezers 21 need to be separated from the sleeve 1, the two sliding blocks 22 can be pressed so that the two sliding blocks 22 are separated from the corresponding sliding grooves 13. After being separated from the corresponding sliding grooves 13, the two sliding blocks 22 are now It is located inside the sleeve 1. At this time, pinch the end of the ear tweezers 21 and take out the sleeve 1. The installation principle is to reverse the above steps. After the first end of the ear tweezers 21 is inserted into the inside of the sleeve 1, the two sliding The block 22 corresponds to the two sliding grooves 13, and the elasticity of the ear tweezers 21 itself will loosen the two sliding blocks 22 to pass through the corresponding sliding grooves 13.

Specifically, the support mechanism 7 includes a support plate 71, a support block 72 and a support arc member 73. The connecting tube 4 is symmetrically provided with two movable grooves 41, and the support block 72 is provided with two. The support blocks 72 are respectively arranged in the corresponding movable grooves 41 and are slidingly matched up and down. There are two support plates 71 , and the two support plates 71 are respectively arranged at the lower ends of the corresponding support blocks 72 and located at Inside the connecting barrel 4, there are two supporting arc-shaped members 73. The two supporting arc-shaped members 73 are respectively provided at the upper end of the supporting block 72 and located outside the connecting barrel 4. The two supporting arc-shaped members 73 The parts 73 are all made of rubber material. The two supporting arc-shaped parts 73 are all made of rubber material, which can reduce the buffering force during the support expansion process and will not cause too much pain and damage to the inside of the ear during the support process. The two support arc members 73 are all made of rubber. The inner side of the support plate 71 is inclined and the lowest point is close to the direction of the ear forceps 21. The head end of the effusion suction tube 6 is elliptical, and the effusion suction tube 6 is The head end of the effusion suction tube 6 is made of tough material and has a slight curvature. The puncture end of the puncture needle 5 is set in a sharp shape. The outer diameter of the puncture needle 5 is the same as the outer diameter of the effusion suction tube 6. It also includes an external ear cover 8. The external ear cover 8 can be placed around the rear end of the ear and is in a matching state with the ear. The external ear cover 8 is provided with a connecting sleeve 81. The connecting sleeve 81 It is snap-fitted with sleeve 1;

During the tympanic membrane puncture treatment of a patient, first the outer ear sleeve 8 is placed on the outside of the patient's ear to be treated, and then the sleeve 1 is inserted into the ear. During the insertion of the sleeve 1, Through the two camera probes 11 on the sleeve 1 and the connecting body, the sleeve 1 and the connecting sleeve 4 reach the designated position inside the ear, and are connected to the outside of the sleeve 1 through the connecting sleeve 81 on the outer sleeve 8 of the ear. Connect to form a support point, as shown in Figure 2. At this time, the fixed barrel 3, the puncture needle 5 and the effusion suction tube 6 do not pass through the ear forceps 21, the sleeve 1 and the connecting barrel 4. At this time, again Pass the first end of the fixed tube 3 through the fixed hole 211 at the end of the ear forceps 21, the sleeve 1 and the connecting tube 4 in sequence. The medical staff can accurately see through the camera probe 11 and move the first end of the fixed tube 3 to the inside of the patient's ear. Next to the eardrum and in a state of almost contact, push the end of the ear forceps 21 so that the head end of the ear forceps 21 passes through the head end of the sleeve 1 and moves toward the inside of the connecting tube 4. The head end of the ear forceps 21 is located in the connecting tube 4 After the interior is in contact with the two support plates 71, it continues to push the end of the ear forceps 21 to move, and the two support plates 71 will change the lateral force of the movement of the ear forceps 21 into a vertical force due to the slope factor, so as to move the two The support plate 71 moves forward symmetrically, and the two support blocks 72 are located in the sliding groove 13 in a sliding fit state, thereby driving the two support arc members 73 to expand symmetrically to form a support point inside the ear. There is a support point inside, so during the puncture treatment process, there will be no risk of puncture treatment failure or secondary injury to the patient due to medical staff's hand shaking and errors.

After the head end of the ear tweezers 21 is located inside the connecting tube 4, according to the different inner diameters of the connecting tube 4 and the sleeve 1, the head ends of the ear tweezers 21 will move inward during the internal movement of the connecting tube 4, and will move inward between the two supports. When the arc-shaped member 73 hits the inside of the ear to form a supporting state, the head end of the ear forceps 21 is also in a state of tightly clamping the fixed cylinder 3, as shown in Figures 8 to 9, thus ensuring that the subsequent puncture needle 5 and the area are securely connected. The liquid suction tube 6 is not affected when passing through the fixed cylinder 3 and is easy to operate. At the same time, medical staff will not risk puncture treatment failure or secondary injury to the patient due to operational errors, and the clamped fixed cylinder 3 is in A stable puncture route is formed inside the patient's ear, thereby improving the quality of puncture treatment and providing medical staff with a more convenient operation and treatment method;

After the fixed cylinder 3 is clamped and limited, the medical staff first passes the puncture needle 5 through the fixed cylinder 3. The path of the fixed cylinder 3 causes the puncture needle 5 to move to the side of the tympanic membrane and puncture the tympanic membrane. After the needle 5 punctures the tympanic membrane, the puncture needle 5 is returned to the original path to extract it from the fixed cylinder 3. Then, the head end of the effusion suction tube 6 to be used to extract the fluid is passed through the puncture needle 5 in the same manner as the puncture needle 5. The fixed cylinder 3 reaches the effusion inside the tympanic cavity, and the head end of the effusion suction tube 6 has a slight curvature. Therefore, when the head end of the effusion suction tube 6 is located at the effusion inside the tympanic cavity, it is in Close to the bottom of the tympanic cavity, at this time, you only need to connect the end of the effusion suction tube 6 to the required extraction equipment to achieve maximum extraction of the effusion. After the extraction equipment is started, the effusion inside the tympanic cavity can be removed. The liquid is extracted. Through the method of extracting the accumulated liquid of the present invention, the accumulated liquid inside the tympanic cavity can be extracted to the maximum extent, so as to facilitate the patient to obtain a better therapeutic effect. In the prior art, the puncture needle 5 is not straight during the puncture process. Entering the tympanic membrane can easily cause blockage at the needle and affect the suction operation. When the puncture needle 5 is positioned inside the tympanic cavity to absorb the fluid, the puncture needle 5 enters straight, and when the fluid accumulation level inside the tympanic cavity is lower than the level of the puncture needle 5 When suctioning the mouth, the required suction force will become larger, thus causing pain to the patient and the risk of secondary injury.
