Abstract

The invention relates to the field of medical apparatus and instruments, and in particular relates to a carpal canal minimally invasive cutter. The carpal canal minimally invasive cutter comprises a cutter fixed part and a cutter movable part, wherein the cutter fixed part comprises a groove track, the groove track is arranged at the front end of a cutter fixed part body, the cutter movable part comprises a cylinder-shaped long pipe and four grasp plates, the cylinder-shaped long pipe can fix a blade, and an inner chamber of the cutter movable part is fixedly arranged at the rear end of a cutter movable part body. Compared with the prior art, the carpal canal minimally invasive cutter provided by the invention has the advantages that the blade of the carpal canal minimally invasive cutter can be matched with an externally connected endoscope for use, the endoscope is internally equipped with a hard pipe with lamplight, the hard pipe is fixed by the four grasp plates, advances or retreats along with the cylinder-shaped long pipe in the groove track, and is matched with the blade for cutting the transverse carpal ligament, the visualization effect is achieved, and the median nerves and other structures are protected from being injured.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to a carpal tunnel minimally invasive tool. Background technique [0002] Clinically, carpal tunnel syndrome is a common nerve entrapment disease, which can cause finger numbness and muscle atrophy. It is a very painful disease for patients. It is common for office workers who operate computers and other manual laborers. In patients with carpal tunnel syndrome, the median nerve is compressed in the carpal tunnel, causing numbness, tingling or burning pain on the radial side of the thumb, index finger, middle finger, and ring finger, which is aggravated at night after working during the day, and even wakes up during sleep; traditional surgery The treatment method is to make a longitudinal incision along the palm and wrist dermatoglyphs. The incision is from the palm to the wrist. The incision is more than 5 centimeters. After the skin is cut, the transverse carpal ligament is cut off to r...
