Description

Minimally invasive releaser for carpal tunnel syndrome

Technical Field

The invention belongs to the technical field of releasers, and particularly relates to a minimally invasive releaser for carpal tunnel syndrome.

Background

Currently, carpal tunnel syndrome (carpaltunnelsyndrome) is a group of symptoms and signs that the median nerve is compressed within the carpal tunnel, and is one of the most common peripheral nerve entrapment syndromes. The carpal tunnel is composed of a bottom wall and two side walls formed by carpal bones, and a transverse carpal ligament is covered on the carpal tunnel to form a bone and fiber tunnel. The tendon of flexor hallucis longus, the deep and superficial tendons of 2-4 fingers and the median nerve pass through the wrist. The median nerve is most superficial and is located between the transverse carpal ligament and other tendons. The tendon of flexor hallucis longus is wrapped by the radial bursa of sideslip, and the other tendons are wrapped by the ulnar bursa of sideslip. When the wrist joint is flexed, the median nerve is pressed, and the fist is forcefully closed, so the pressure is more severe. The posterior branch of the median nerve, exiting the carpal tunnel, innervates the greater thenar muscles, the 1 st and 2 nd lumbrical muscles, the radial palm and the 3 semiphalangeal cutaneous sensations, with the exception of the adductor pollicis.

At present, the carpal tunnel syndrome is treated by adopting an operation mode, but the method has large wound, is easy to lose other important tissues, and has long recovery time and large scars.

Through the above analysis, the problems and defects of the prior art are as follows: at present, the carpal tunnel syndrome is treated by adopting an operation mode, but the method has large wound, is easy to lose other important tissues, and has long recovery time and large scars.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Aiming at the problems in the prior art, the invention provides a minimally invasive releaser for carpal tunnel syndrome, which is described in detail in the following with reference to the attached drawings.

As shown in fig. 1 to 2, the minimally invasive releaser for carpal tunnel syndrome provided by the invention comprises: 1. a separator; 2. a probe body; 3. a handle; 4. a blade; 5. a push rod.

One end of the minimally invasive device body is integrally provided with a head part: including separator 1, above be fixed with arc blade 4, the somatic part: including disjunctor 1, probe 2, the afterbody: comprises a grab handle 3 and a push rod 5. The cross section of the head part of the minimally invasive instrument is a separating body 1 with two sides of arc-shaped inverted triangles, the body part of the minimally invasive instrument is provided with the separating body 1 and a probe 2 thereon, and the total length of the head part and the body part is 40 mm. The blade can adopt a titanium alloy blade or a stainless steel blade, the main body part can adopt macromolecule-based ethylene, and the push rod and the handle part can adopt titanium alloy metal or stainless steel metal. The blade can adopt a titanium alloy blade or a stainless steel blade, the main body part can adopt macromolecule-based ethylene, and the push rod and the handle part can adopt titanium alloy metal or stainless steel metal.

Preferably, the main body part of the minimally invasive device body comprises a separating body and a detecting body, wherein the cross section of the separating body is 5mm in height, the width of the separating body is 5mm, and the height of the detecting body is 5 mm.

Preferably, the push rod is a cylinder, and the diameter of the push rod is 8mm, and the length of the push rod is 50 mm.

The working principle of the invention is as follows: the median nerve and the ulnar flexor tendon are exposed in the operation, a handheld push rod 5 is embedded between the median nerve and the ulnar flexor tendon by a carpal tunnel syndrome minimally invasive releaser (a blade faces to a transverse carpal support band) to push forwards, the separating body 1 can automatically separate the nerve and tendon tissues, and the front end of the grab handle 3 is clamped by the cut skin after the depth is about 40mm, so that the blade 4 cannot continuously advance to prevent the blade 4 from entering the peripheral normal tissues such as the nerve, the tendon, the blood vessel and the like which are lost too deeply; the hyperplasia thickness of the wrist transverse supporting belt is about 3mm-4mm, and a protruding part (a detecting body 2) is designed on the back of the main body to detect whether the wrist transverse supporting belt is cut thoroughly by the blade 4.

The above description is only for the purpose of illustrating the present invention and the appended claims are not to be construed as limiting the scope of the invention, which is intended to cover all modifications, equivalents and improvements that are within the spirit and scope of the invention as defined by the appended claims.
