Transverse carpal ligament closing and separating device for treating carpal tunnel syndrome

Abstract

The invention discloses a transverse carpal ligament closing and separating device for treating carpal tunnel syndrome. The transverse carpal ligament closing and separating device comprises a bottom plate, an upper pressing plate and a hook push broach, wherein the bottom plate is of a hollow structure, one end of the bottom plate is a guide end with a guide structure, the guide end is closed, and the other end of the bottom plate is an insertion end with an insertion opening; an opening is formed in the upper side of the bottom plate, the upper pressing plate is detachably arranged at the opening side of the bottom plate, and a locating space for locating a transverse carpal ligament is formed between the upper pressing plate and the bottom plate and at one end close to the guide end; and one end of the hook push broach is a cutting end with a blade, the other end of the hook push broach is a handheld end, and the cutting end of the hook push broach is inserted from the insertion end of the bottom plate and can reciprocate along the length direction of the bottom plate, so that the blade of the cutting end can cut the transverse carpal ligament in a reciprocating mode. According to the transverse carpal ligament closing and separating device, the transverse carpal ligament is separated in the locating space by adopting the hook push broach, iatrogenic accidents caused due to the fact that a median-nerve superficial palmar arch is clamped and pressed by an operation device are prevented, and it is ensured that the transverse carpal ligament is completely separated and blood vessel nerves are not damaged.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a transverse carpal ligament closure and disconnector for treating carpal tunnel syndrome. Background technique [0002] Carpal tunnel syndrome (CTS) is an increase in the pressure in the carpal tunnel caused by various factors, resulting in compression of the median nerve, ischemia, and dysfunction of the corresponding innervated area. It is the most common form of entrapment. Peripheral neuropathy. [0003] Surgery is the most effective treatment for carpal tunnel syndrome. Traditional volar large "S" incision carpal tunnel decompression has the disadvantages of long surgical incision, large trauma, extensive postoperative scar tissue formation, pain in the incision area, and long recovery time, so it has been seldom used at present. Small incisions for the treatment of carpal tunnel syndrome have the advantages of less damage and concealed scars. Currently, they are ...
