Description
Technical Field
The utility model belongs to the technical field of medical instrument, concretely relates to slide sword of carpal tunnel syndrome.
Background
Carpal tunnel syndrome (carpal tunnel syndrome) is the most common one of peripheral nerve entrapment syndromes, which is a series of symptoms and signs caused by entrapment of the median nerve in the wrist. Preferably, the disease is about 30-50 years old, female is 5 times as much as male, bilateral disease patients account for 1/3-1/2, and the ratio of female to male is 9: 1. The median nerve of the wrist is pressed, the thumb, the index finger and the middle finger are painful and numb in sensation, sensory dysfunction at the tip of the finger is usually presented in the initial stage, the finger is usually awakened due to numbness or burning pain for hours after falling asleep and is relieved after activity, the neurotrophic disorder occurs due to long disease course of a few patients, the internaloid muscle atrophy occurs, and the current treatment mode is mainly conservative treatment and surgical treatment.
The main modes of operation treatment include a traditional open operation mode, an arthroscopic minimally invasive operation mode and a single or double small incision minimally invasive operation mode. The instrument for cutting off the transverse carpal ligament in the arthroscopic treatment of the carpal tunnel syndrome is a miniature push broach, the bottom of the front end of the knife edge of the miniature push broach is provided with an elliptical flat bottom support, the foremost edge of the miniature push broach is about 0.5 cm longer than the knife edge, and the miniature push broach is mostly matched with a semi-open U-shaped groove sleeve (Wolf company in Germany) and an endoscope system (Sony company in Japan) for operation. The system has high operation cost, high requirement on operation skill and immature operation technology, and is not suitable for treating carpal tunnel syndrome by single or double small incision minimally invasive operation. If the miniature push broach is used for minimally invasive small incision surgery, the distal end of the miniature push broach is in a sheet shape, and a median nerve protection device is not arranged, so that the median nerve below a carpal tunnel is easy to cut and damage. Therefore, at present, no effective instrument suitable for the single or double small incision minimally invasive surgery for incising the transverse carpal ligament exists, the single or double small incision minimally invasive surgery for treating the carpal tunnel syndrome is influenced, and the solution is urgently needed.
