A visual tympanic membrane puncture needle and its use method

Abstract

The present invention discloses a visual tympanic membrane puncture needle and a method for using the same, belonging to the technical field of medical equipment, comprising a sleeve, an ear clip, a fixing tube, a connecting tube, a puncture needle and a fluid suction tube. Through the method of extracting the fluid in the present invention, the fluid accumulated in the tympanic cavity can be extracted to the maximum extent, which can facilitate patients to obtain better treatment effects and provide medical staff with a more convenient operation and treatment. The prior art does not suffer from the problem that the puncture needle directly enters the tympanic membrane during the puncture process, which can easily cause needle blockage and affect the suction operation. When the puncture needle is located inside the tympanic cavity and is ready to absorb the fluid, the puncture needle enters straightly, which poses a certain risk. When the level of the fluid accumulated in the tympanic cavity is lower than the suction port of the puncture needle, the required suction force will become greater, thereby causing pain to the patient and the risk of secondary injury.

Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a visible tympanic membrane puncture needle and a use method thereof. Background Art

[0002] Otolaryngology is a surgical discipline that diagnoses and treats the ears, nose, pharynx, larynx and related head and neck areas. With the advancement and development of science and technology, various medical disciplines have penetrated and promoted each other, expanding the scope of otolaryngology. The emergence of ear microsurgery, ear neurosurgery, skull base surgery, audiology and balance science, nasal endoscopic surgery, nasal neurosurgery (nasal skull base surgery), head and neck surgery, laryngeal microsurgery, voice and speech disorders, pediatric otolaryngology, etc. has greatly enriched the content of otolaryngology.

[0003] Tympanic membrane puncture is a commonly used procedure in clinical practice 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 can also be used to inject medication into the middle ear to treat some middle ear and inner ear diseases. As a routine procedure, tympanic membrane puncture can usually be performed in an outpatient clinic.

[0004] At present, the traditional treatment method is to use a device similar to a syringe. After the needle puncture operation is completed, it is sucked out by means of a syringe. However, if the required effusion is large and one extraction cannot meet the extraction of the effusion, this method will be performed multiple times. Therefore, the patient will have a greater fear of treatment and will also affect the quality of treatment and cause secondary harm to the patient. Therefore, it is impossible to puncture the same hole for multiple times, which means that multiple holes need to be punctured. In addition, since the puncture needle is straight after puncturing the tympanic membrane and is located in the tympanic cavity to extract liquid, and the tympanic cavity is curved, the puncture needle is in a straight state, and it is impossible to extract liquid below the puncture needle. When medical staff insert the needle straightly during the puncture process, it is easy for the needle to shake due to hand tremors, causing damage to the patient's ear, which will directly affect the treatment process. If there is too much dirt during the tympanic membrane puncture and fluid extraction process, it is difficult to remove, and the puncture needle enters the tympanic membrane straight during the puncture process, it is easy to cause needle blockage and affect the suction operation. When the puncture needle is inserted into the tympanic cavity and is ready to absorb the accumulated fluid, the puncture needle enters straightly. When the level of accumulated fluid in the tympanic cavity is lower than the suction port of the puncture needle, the required suction force will become greater, thereby causing pain and the risk of secondary injury. Therefore, the present device provides a visual tympanic membrane puncture needle and a method of using it. Summary of the invention

[0015] A method for using a visual tympanic membrane puncture needle comprises the following steps:

[0016] S1: First, before the puncture treatment, the dirt inside the patient's ear is removed according to the patient's ear dirt condition;

[0017] S2: The external ear fixing piece is then sleeved on the outside of the ear, and the ear clip is mounted on the sleeve, and the sleeve is connected to the external ear fixing piece and extends into the inside of the ear;

[0018] S3: Pass the fixing tube through the ear clip and the sleeve to the side of the eardrum inside the ear, and pass the puncture needle through the fixing tube, the ear clip and the sleeve to the side of the eardrum inside the ear;

[0019] S4: Then push the ear clip to the inside of the connecting tube, unfold the two supporting arc parts to support and fix the inside of the ear, and a good working environment can be achieved through external and internal fixation, and continue to push the ear clip, so that the fixing tube is squeezed to form a clamping limit state;

[0020] S5: At this time, the puncture needle slowly moves toward the eardrum in the fixed tube and punctures the eardrum. After the puncture is completed, the puncture needle returns to the original path and is taken out;

[0021] S6: The required effusion aspiration tube is then passed through the fixing tube, the ear clip, and the sleeve located at the lateral end of the tympanic membrane inside the ear in a puncture needle motion manner, and extended into the tympanic cavity, so that the fluid can be extracted;

[0022] S7: After the fluid aspiration tube is inserted, the head end of the fluid aspiration tube is located at the fluid accumulation inside the tympanic cavity. The head end of the fluid aspiration tube has a slight bend and is located close to the bottom of the fluid accumulation inside the tympanic cavity. At this time, the maximum extraction of the fluid can be achieved by simply connecting the end of the fluid aspiration tube to the required extraction equipment.

[0023] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0024] Firstly, after the fixed tube of the device is clamped and limited in position, the medical staff will first pass the puncture needle through the fixed tube, and move the puncture needle to the side of the tympanic membrane through the route trajectory of the fixed tube, and puncture the tympanic membrane. After the tympanic membrane is punctured by the puncture needle, the puncture needle will return to the original path and be pulled out from the fixed tube. Then, the head end of the fluid suction tube for extracting the effusion is passed through the fixed tube in the manner of the puncture needle until it reaches the effusion inside the tympanic cavity. The head end of the fluid suction tube has a slight curvature, so when the head end of the fluid suction tube is located at the effusion inside the tympanic cavity, it is close to the bottom of the effusion inside the tympanic cavity. At this time, it is only necessary to connect the end of the fluid suction tube to the required extraction device to achieve maximum extraction of the effusion. The extraction device can extract the accumulated fluid in the tympanic cavity after being started. The method of extracting the accumulated fluid through the present invention can maximize the extraction of the accumulated fluid in the tympanic cavity, which can facilitate patients to obtain better treatment effects and provide medical staff with more convenient operation and treatment. It will not cause clogging of the needle tip that affects the suction operation because the puncture needle enters the tympanic membrane straightly during the puncture process in the prior art. When the puncture needle is inserted into the tympanic cavity to prepare for sucking the accumulated fluid, the puncture needle enters straightly, which has certain risks during the entry and can easily cause internal ear injuries to the patient. When the level of accumulated fluid in the tympanic cavity is lower than the suction port of the puncture needle, the required suction force will become greater, thereby causing pain to the patient and the risk of secondary injury.

[0025] Secondly, during the process of tympanic membrane puncture treatment for the required patient, the device first sets the external ear sleeve on the outside of the patient's ear to be treated, and then, after the sleeve is inserted into the ear, during the sleeve insertion process, the present invention is in a whole after splicing is completed, and through the two camera probes on the sleeve and the connector, the sleeve and the connecting tube reach the specified position inside the ear, and are snap-connected with the outside of the sleeve through the connecting sleeve on the external ear sleeve to form a support point. At this time, the fixed tube, puncture needle and effusion suction tube do not pass through the ear tweezers, sleeve and connecting tube. At this time, the head end of the fixed tube is passed through the fixed hole at the end of the ear tweezers, the sleeve and the connecting tube in turn, and the medical staff accurately checks through the camera probe to move the head end of the fixed tube to the patient's ear. The eardrum is next to the eardrum and is almost in contact with it, and then the end of the ear tweezers is pushed so that the head end of the ear tweezers passes through the head end of the sleeve and moves toward the inside of the connecting tube. After the head end of the ear tweezers is located inside the connecting tube and contacts the two support plates, the end of the ear tweezers is continuously pushed to move. The two support plates will change the lateral force of the ear tweezers into a vertical force due to the inclined surface to move the two support plates symmetrically. The two support blocks are located in the sliding groove and are in a sliding fit state, thereby driving the two supporting arc-shaped parts to symmetrically expand toward each other 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, there will be no risk of failure of puncture treatment and secondary injury to the patient due to hand shaking and operational errors of medical staff.

[0026] Thirdly, 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 end of the ear tweezers will move inward during the movement inside the connecting tube, and when the two supporting arc-shaped members abut against the inside of the ear to form a supporting state, the head end of the ear tweezers is also in a state of tightly clamping the fixed tube, thereby ensuring that the subsequent puncture needle and the effusion suction tube are not affected during the process of passing through the fixed tube and the operation is convenient. At the same time, medical staff will not cause puncture treatment failure due to operational errors and the risk of secondary injury to the patient, and the clamped fixed tube forms a stable puncture route trajectory inside the patient's ear, thereby improving the quality of puncture treatment and providing medical staff with a more convenient operation and treatment method.

[0027] Fourthly, since too much dirt inside the ear will affect the puncture treatment, the dirt inside the patient's ear needs to be removed before the puncture treatment. When removing the dirt inside the patient's ear, the medical staff first extends the sleeve into the patient's ear. At this time, the connecting tube is not connected to the sleeve, and then the ear tweezers inside the sleeve are pushed through the conical position of the sleeve head end. At this time, the ear tweezers are slightly closed, and the specific distribution of the dirt inside the ear can be viewed through the camera probe on the sleeve. After the medical staff visually observes the dirt position to be removed, the medical staff moves the ear tweezers head end moved by the sleeve to the dirt removal position At this time, it is only necessary to push the pushing block on the two pushing grooves to move toward the head end of the ear tweezers, so that after the pushing block contacts the two sliding blocks, and when the inclined surfaces of the two sliding blocks are horizontally squeezed by the pushing blocks, the two sliding blocks will symmetrically move toward their respective directions, and because the ear tweezers have a certain toughness and elasticity, the two ends of the head end of the ear tweezers will also symmetrically move toward their respective directions to achieve a clamping effect, so that the dirt can be clamped at the dirt removal position where the head end of the ear tweezers moves, and the dirt can be removed by taking out the sleeve. After the dirt is taken out one by one in the above manner, it is sufficient to achieve the effect of not affecting the puncture treatment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0045] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0046] Reference Figures 1 to 13As shown, an embodiment of the present invention provides a visual tympanic membrane puncture needle, comprising a sleeve 1, an ear clip 2, a fixed tube 3, a connecting tube 4, a puncture needle 5 and an effusion suction tube 6, the head end of the sleeve 1 and the head end of the connecting tube 4 are both conically arranged, the end of the connecting tube 4 is arranged at the head end of the sleeve 1 and is clamped, the connecting tube 4 is provided with a supporting mechanism 7 for fixation in the ear, one end of the ear clip 2 extends into the interior of the sleeve 1, the fixed tube 3 passes through the ear clip 2, the sleeve 1 and the connecting tube 4, the puncture needle 5 passes through the fixed tube 3, the ear clip 2, the sleeve 1 and the connecting tube 4, and the effusion suction tube 6 can pass through the fixed tube 3, the ear clip 2, the sleeve 1 and the connecting tube when the puncture needle 5 does not pass through the fixed tube 3, the ear clip 2, the sleeve 1 and the connecting tube 4. 4. The head end of the sleeve 1 and the head end of the connecting tube 4 are both provided with a camera probe 11. Through the method of extracting the effusion of the present invention, the effusion in the tympanic cavity can be extracted to the maximum extent, which can facilitate patients to obtain better treatment effects and provide more convenient operation and treatment for medical staff. In the prior art, the puncture needle 5 enters the tympanic membrane straightly during the puncture process, which easily causes the needle to be blocked and affects the suction operation. When the puncture needle 5 punctures the tympanic cavity and is ready to absorb the effusion, the puncture needle 5 enters straightly, which has certain risks and is easy to cause internal ear injuries of the patient. When the effusion level in the tympanic cavity is lower than the suction port of the puncture needle 5, the required suction force will become greater, thereby causing pain to the patient and the risk of secondary injury.

[0047] The sleeve 1, ear clip 2, fixed tube 3, connecting tube 4, puncture needle 5 and effusion suction tube 6 in the present invention are all spliced ​​together and each component can be disassembled separately. Each component can achieve another effect after splicing based on its own necessary function, and the splicing method of each component is relatively convenient. After use, the components of the present invention can be disassembled one by one to facilitate subsequent disinfection and cleaning operations, to prepare for the next puncture treatment, and to avoid cross infection between patients during treatment and use. The sleeve 1 itself can be inserted into the ear through the sleeve 1 and the specific situation inside the patient's ear can be observed through the camera sleeve 1. The ear clip 2 itself can be used to clamp and 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 hazards when medical staff hold the puncture needle for treatment.

[0048] Specifically, the sleeve 1 is symmetrically provided with two push grooves 12, and the sleeve 1 is also provided with two sliding grooves 13 and are symmetrically arranged. The ear clip 2 includes ear tweezers 21, a sliding block 22 and a push block 23. The ear tweezers 21 are of a traditional tweezer shape and have the same function as the tweezers. The head end of the ear tweezers 21 is elliptical, and there are two sliding blocks 22. The two sliding blocks 22 are respectively arranged on both sides of the ear tweezers 21 and respectively pass through the corresponding sliding grooves 13 and are slidably matched with the corresponding sliding grooves 13. The upper and lower sides of the push block 23 are respectively located on the corresponding push grooves 12. The connection method of the upper and lower sides of the push block 23 and the corresponding push groove 12 is the same as the principle structure of the push gear position in the card slot on the traditional flashlight. The upper ends of the two sliding blocks 22 are both inclined and the end close to the push block 23 is the lowest point. The end of the ear tweezers 21 is provided with a fixed hole 211, and the inner diameter of the fixed hole 211 is adapted to the outer diameter of the fixed tube 3 to facilitate the fixed tube 3 to pass through;

[0049] Since too much dirt inside the ear will affect the puncture treatment, it is necessary to remove the dirt inside the patient's ear before the puncture treatment. When removing the dirt inside the patient's ear, the medical staff first extends the sleeve 1 into the patient's ear, at which time the connecting tube 4 is not connected to the sleeve 1, and then pushes the ear tweezers 21 inside the sleeve 1 through the conical position at the head end of the sleeve 1. Figure 7 As shown, at this time, the head end of the ear tweezers 21 is closed, and the specific distribution of the dirt inside the ear can be viewed through the camera probe 11 on the sleeve 1. After the medical staff can visually observe the dirt position to be removed, the medical staff moves the head end of the ear tweezers 21 moved by the sleeve 1 to the position where the dirt is required to be removed. At this time, it is only necessary to push the push block 23 to move in the direction of the head end of the ear tweezers 21 on the two push grooves 12, so that the push block 23 contacts the two sliding blocks 22, and in the process where the inclined surfaces of the two sliding blocks 22 are horizontally squeezed by the push block 23, the two sliding blocks 22 will symmetrically move toward their respective directions, and because the ear tweezers 21 have a certain toughness and elasticity, the two ends of the head end of the ear tweezers 21 will also symmetrically move toward their respective directions to achieve a clamping effect, so that the dirt can be clamped at the dirt removal position where the head end of the ear tweezers 21 moves, and the dirt can be removed by taking out the sleeve 1. After the dirt is taken out one by one in the above-mentioned manner, it can be achieved without affecting the puncture treatment;

[0050] Since the ear tweezers 21 cannot be squeezed to clamp the ear tweezers 21 after they are inserted into the ear in the sleeve 1 and the force may be limited, two sliding blocks 22 and a pushing block 23 are provided, and two pushing grooves 12 and two sliding grooves 13 are provided on the sleeve 1 to cooperate to realize the clamping operation of the head end of the ear tweezers 21;

[0051] When the ear tweezers 21 need to be separated from the sleeve 1, the two sliding blocks 22 can be pressed to disengage the two sliding blocks 22 from the corresponding sliding grooves 13. After disengaging from the corresponding sliding grooves 13, the two sliding blocks 22 are now located inside the sleeve 1. At this time, the sleeve 1 can be taken out by pinching the ends of the ear tweezers 21. The installation principle can be reversed according to the above steps. After the head ends of the ear tweezers 21 are inserted into the sleeve 1, the two sliding blocks 22 correspond 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.

[0052] Specifically, the support mechanism 7 includes a support plate 71, a support block 72 and a support arc 73. Two movable grooves 41 are symmetrically provided on the connecting tube 4. The support block 72 is provided with two, and the two support blocks 72 are respectively arranged in the corresponding movable grooves 41 and are both slidably matched up and down. The support plate 71 is provided with two, and the two support plates 71 are respectively arranged at the lower ends of the corresponding support blocks 72 and located inside the connecting tube 4. The support arc 73 is provided with two, and the two support arcs 73 are respectively arranged at the upper ends of the support blocks 72 and located outside the connecting tube 4. The two support arcs 73 are both made of rubber. The two support arcs 73 are made of rubber and can be used in the support expansion process. Reducing the buffering force during the support process will also not cause too much pain and damage to the inside of the ear during the support process. The two support plates 71 are inclined on the inner side and are at the lowest point close to the ear forceps 21. The head end of the effusion suction tube 6 is elliptical. The effusion suction tube 6 is made of a tough material and the head end of the effusion suction tube 6 has a little curvature. The puncture end of the puncture needle 5 is sharp. 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 ear outer sleeve 8, which can be sleeved on the outer part of the rear end of the ear and is in a compatible state with the ear. The ear outer sleeve 8 is provided with a connecting sleeve 81, and the connecting sleeve 81 and the sleeve 1 are in a snap-on arrangement;

[0053] During the tympanic membrane puncture treatment of the required patient, the ear outer sleeve 8 is first 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, the sleeve 1 and the connecting tube 4 are connected to the specified position inside the ear through the two camera probes 11 on the sleeve 1 and the connector, and the connecting sleeve 81 on the ear outer sleeve 8 is connected to the outer side of the sleeve 1 to form a support point. Figure 2As shown, at this time, the fixed tube 3, the puncture needle 5 and the effusion suction tube 6 have not passed through the ear forceps 21, the sleeve 1 and the connecting tube 4. At this time, the head end of the fixed tube 3 is passed 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 accurately checks through the camera probe 11 that the head end of the fixed tube 3 is moved to the side of the eardrum inside the patient's ear and is in a state of almost contact, and then pushes 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 into the connecting tube 4. After the head end of the ear forceps 21 is located inside the connecting tube 4 and contacts the two support plates 71, the medical staff holds the fixed tube 3. The end of the ear forceps 21 is continuously pushed to move, and the two support plates 71 will change the lateral force of the ear forceps 21 into a vertical force due to the inclined surface, so as to move the two support plates 71 symmetrically forward, and the two support blocks 72 are located in the sliding groove 13 in a sliding matching state, thereby driving the two support arc members 73 to symmetrically unfold forward to form a support point inside the ear. The present invention has a support point both outside and inside the ear, so during the puncture treatment process, there will be no risk of puncture treatment failure and secondary injury to the patient due to hand shaking and operation errors of medical staff;

[0054] After the head end of the ear tweezers 21 is located inside the connecting tube 4, due to the different inner diameters of the connecting tube 4 and the sleeve 1, the head end of the ear tweezers 21 will move inwards during the movement inside the connecting tube 4, and when the two supporting arc-shaped members 73 abut against the inside of the ear to form a supporting state, the head end of the ear tweezers 21 is also in a state of tightly clamping the fixed tube 3, refer to Figures 8 to 9 As shown, it is ensured that the subsequent puncture needle 5 and the effusion suction tube 6 are not affected during the process of passing through the fixed tube 3 and the operation is convenient. At the same time, the medical staff will not cause the risk of puncture treatment failure and secondary injury to the patient due to operational errors, and the clamped fixed tube 3 forms a stable puncture route trajectory inside the patient's ear, thereby improving the quality of puncture treatment and providing a more convenient operation treatment method for medical staff;

[0055] After the fixed cylinder 3 is clamped and limited, the medical staff first passes the puncture needle 5 through the fixed cylinder 3, and moves the puncture needle 5 to the side of the tympanic membrane through the route trajectory of the fixed cylinder 3, and punctures the tympanic membrane. After the tympanic membrane is punctured by the puncture needle 5, the puncture needle 5 is returned to the original path and thus drawn out of the fixed cylinder 3. Then, the head end of the fluid suction tube 6 for extracting the effusion is passed through the fixed cylinder 3 in the manner of the puncture needle 5 until it reaches the effusion inside the tympanic cavity. The head end of the fluid suction tube 6 has a slight curvature. Therefore, when the head end of the fluid suction tube 6 is located at the effusion inside the tympanic cavity, it is close to the bottom of the effusion inside the tympanic cavity. At this time, it is only necessary to pull the fluid suction tube 6 The end of the puncture needle 5 is connected to the required extraction device to achieve maximum extraction of the accumulated fluid. After the extraction device is started, the accumulated fluid in the tympanic cavity can be extracted. The method of extracting the accumulated fluid in the tympanic cavity according to the present invention can maximize the extraction of the accumulated fluid in the tympanic cavity, so as to facilitate patients to obtain better treatment effects. In the prior art, the puncture needle 5 enters the tympanic membrane straightly during the puncture process, which can easily cause clogging at the needle and affect the suction operation. When the puncture needle 5 punctures the inside of the tympanic cavity and prepares to absorb the accumulated fluid, the puncture needle 5 enters straightly. When the level of the accumulated fluid in the tympanic cavity is lower than the suction port of the puncture needle 5, the required suction force will become greater, thereby causing pain to the patient and the risk of secondary injury.

[0056] A method for using a visual tympanic membrane puncture needle comprises the following steps:

[0057] S1: First, before the puncture treatment, the dirt inside the patient's ear is removed according to the patient's ear dirt condition;

[0058] S2: The external ear fixing piece is then sleeved on the outside of the ear, and the ear clip 2 is mounted on the sleeve 1, and the sleeve 1 is connected to the external ear fixing piece and extends into the inside of the ear;

[0059] S3: Then pass the fixing tube 3 through the ear clip 2 and the sleeve 1 to the side of the eardrum inside the ear, and pass the puncture needle 5 through the fixing tube 3, the ear clip 2 and the sleeve 1 to the side of the eardrum inside the ear;

[0060] S4: Then push the ear clip 2 to the inside of the connecting tube 4, unfold the two supporting arc members 73 to support and fix the inside of the ear, and a good working environment can be achieved through external and internal fixation, and the ear clip 2 is continuously pushed, and the fixing tube 3 is squeezed to form a clamping limit state;
