detailed description

Please refer to Fig. 1, in order to better understand the technical solution of the present invention, the inventor of the utility model will describe in detail below in conjunction with the accompanying drawings through specific embodiments:

Please refer to FIG. 1 , a joint intervention kit of the present invention includes a dilator 1 , a sleeve 2 , a support inner core (not shown in the figure), a hook knife 3 , a spatula 4 and a stripper 5 .

The dilator 1 includes a round blunt piercing cone 11 and a dilator handle 12 coaxially connected to the tail end of the round blunt piercing cone 11 . Wherein, the width d1 of the blunt puncture cone 11 is divided into two specifications of 6mm and 7mm, which are suitable for patients with different palm sizes. The handle part 12 of the dilator is connected to the tail end of the puncture cone 11 with a blunt tip through the dilator conical part 121 located at the front end of the dilator. A dilator anti-slip groove 122 parallel to the axial direction of the dilator handle 12 is also provided on the outer wall of the dilator handle 12 . The blunt puncture cone 11 can be easily inserted into the patient's carpal tunnel. The conical portion 121 of the dilator and the anti-skid groove 122 of the dilator are convenient for the doctor to hold and reduce damage to the patient caused by misoperation. During the operation, the dilator 1 is first inserted from the proximal end of the wrist joint through the skin incision, so as to achieve the purpose of expansion and facilitate the insertion of the cannula 2 later.

The cannula 2 includes a cannula body 21 and a cannula handle 22 coaxially connected to the tail end of the cannula body 21 . The width d2 of the cannula body 21 is divided into two specifications of 6 mm and 7 mm, which are suitable for patients with different palm sizes. The cannula handle portion 22 is connected to the tail end of the cannula body 21 through the cannula conical portion 221 at its front end. Both the front end surface and the bottom surface of the sleeve body 21 are arc surfaces. A waist circular groove 211 is provided on the top surface of the sleeve body 21 , and the axial direction of the waist circular groove 211 is parallel to the axial direction of the sleeve body 21 . The tail end of the round waist groove 211 is tangent to the front end of the sleeve handle 22 . The distance a1 between the front end of the round waist groove 211 and the front end of the sleeve body 21 is equal to the distance a2 between the side of the waist round groove 211 and the side of the sleeve body 21 . The support inner core is fixed in the round waist groove 211 .

The outer wall of the sleeve handle 22 is also provided with a sleeve anti-slip groove 222 parallel to the axial direction of the sleeve handle 22, and a sleeve vertical to the outer wall of the sleeve handle 22 and parallel to the top surface of the sleeve body 21. The positioning flank 223 of. The top surface of the sleeve handle 22 is provided with a chute 224 inclined to the sleeve body 21, and the chute 224 extends from the rear end of the sleeve handle 22 to the front end of the sleeve handle 22, that is, the front end of the chute 224 The front end of the sleeve handle 22 is flush with the chute 224 and the sleeve handle 22 is horizontally and equally long in a direction parallel to the axial direction of the sleeve handle 22 . The axial direction of the chute 224 is parallel to the axial direction of the round groove 211 on the top surface of the sleeve body 21 .

The tail end of the cannula handle 22 is also provided with an arthroscopic through hole 225 parallel to the axial direction of the cannula handle 22 , and the arthroscopic through hole 225 communicates with the waist circular groove 211 .

The front end surface of the sleeve body 21 is a circular arc surface, and the waist circular groove 211 is equipped with a support inner core, which increases the stability of the sleeve body 21 and facilitates insertion into the carpal tunnel. After the sleeve body 21 is inserted into the carpal tunnel of the patient, the support inner core is taken out along the chute 224, and the hook knife 3, the spatula 4 or the stripper 5 are placed in the chute 224, and the chute 224 makes the hook knife 3, the spatula 4 and the stripper 5 are more stable in and out of the casing 2, reducing damage to patients caused by misoperation. Insert the arthroscope 6 into the waist circle groove 211 along the axial direction of the arthroscope through hole 225 to replace the supporting inner core. In order for the doctor to clearly see the fibrous tissue of the joint ligament; the depth h of the lumbar groove 211 is suitable for the arthroscope 6 to work normally after inserting and replacing the support inner core.

The conical portion 221 of the cannula and the anti-skid groove 222 of the cannula are convenient for the doctor to hold to reduce the damage caused by misoperation to the patient, and the positioning flanks 223 are convenient for clamping the cannula 2 with surgical forceps during the operation.

The hook knife 3 includes a hook knife body 31 and a hook knife handle 32 axially connected to the rear end of the hook knife body 31 . The hook knife handle 32 is supported by the groove bottom of the chute 224. The blade of the hook knife body 31 is positioned at the front end of the hook knife body 31. The entry into the carpal tunnel starts from the distal end of the ligament and cuts reciprocally under the ligament.

The blade 4 includes a blade body 41 and a blade handle 42 axially connected to the tail end of the blade body 41 . The shovel handle 42 is supported by the groove bottom of the chute 224, the knife face 411 of the shovel body 41 is close to the groove bottom of the chute 224, the cutting edge 412 of the shovel body 41 is positioned at the front end of the shovel body 41, and the shovel body The cutting edge 412 of 41 shrinks toward the tail end of the blade body 41, so that the cutting edge 412 of the blade body 41 is shovel-shaped. During the procedure, a spatula 4 is inserted proximally from the carpal tunnel to incise the ligament.

The stripper 5 includes a stripper body 51 and a stripper handle 52 axially connected to the tail end of the stripper body 51 . The front end of the stripper body 51 is oval and slightly upturned to form a stripping spoon 511 . The peeling spoon 511 can be pushed inward to push the surrounding tissues, and can also be moved when pulled out. The edge of the stripper body 51 is rounded so that the periphery of the stripper body 51 will not be damaged when it moves. After cutting the incision, insert the stripper 51 into the carpal tunnel at first, and push it back and forth to keep the carpal tunnel unobstructed, so that other instruments can be inserted into the carpal tunnel for surgery later.

In summary, the dilator 1, cannula 2, hook knife 3, spatula 4, and stripper 5 in the joint intervention suit of the present utility model have a good degree of cooperation, and the operation difficulty is low during the operation, which reduces joint pain. The difficulty of ligamentotomy reduces the risk of surgery for patients.

Those of ordinary skill in the art should recognize that the above embodiments are only used to illustrate the utility model, rather than as a limitation to the utility model, as long as within the spirit of the utility model, the above-mentioned The changes and modifications of the embodiments will all fall within the scope of the claims of the present utility model.
