Minimally invasive surgical instrument for puncture cutting

Abstract

The invention discloses a minimally invasive surgical instrument for puncture cutting, and belongs to the field of surgical instruments. The minimally invasive surgical instrument is used for treating carpal tunnel syndromes and comprises a sterile arc-shaped needle and a wire saw. The wire saw is connected to the tail of the sterile arc-shaped needle; the diameter of the sterile arc-shaped needle ranges from 0.4mm to 0.6mm, and the length of the sterile arc-shaped needle ranges from 13mm to 25mm; and the diameter of the wire saw ranges from 0.07mm to 0.09mm, and the length of the wire saw ranges from 30mm to 50mm. According to the technical scheme, the minimally invasive surgical instrument has the advantages of simple structure, convenience in operation, extremely small surgical wound, low surgical cost and the like, and is applicable to minimally invasive surgery for puncture cutting.

Description

technical field [0001] The invention belongs to the field of surgical instruments, and in particular relates to a minimally invasive surgical instrument for puncture and cutting. Background technique [0002] Take carpal tunnel syndrome as an example. Carpal tunnel syndrome is a group of symptoms and signs caused by the compression of the median nerve in the carpal tunnel. It is the most common type of peripheral nerve compression syndrome. The carpal tunnel is composed of the carpal bone at the bottom and side walls, above which is a bony and fibrous tunnel covered by the transverse carpal ligament. There is flexor hallucis longus tendon in the carpal tunnel. The deep and superficial flexor tendons of 2 to 4 fingers pass through the median nerve. The median nerve is the most superficial and is located between the transverse carpal ligament and other tendons. The flexor hallucis longus tendon wraps around the radial bursa , the other tendons are wrapped by the ulnar bursa. ...

AI Technical Summary

Problems solved by technology

[0003] Surgical treatment of the transverse carpal ligament generally adopts open surgery and wrist arthroscopic surgery. Although the current open surgery can completely incise the transverse carpal ligament and fully release the median nerve, large surgical incisions are likely to cause complications, such as columnar pain, scars, and so on. pain, palmar cutaneous branch pseudoneuroma of the median nerve, and infection

With the advancement of science and technology, endoscopy has been widely used in clinics, because of the small surgical incision and fast postoperative recovery. As a kind of endoscope, wrist arthroscopy has become a treatment method for the treatment of wrist diseases, but the wrist arthroscopy system It is relatively expensive and can only be obtained in large general hospitals, and it is difficult for grassroots hospitals to afford the purchase cost; and the learning curve of wrist arthroscopy is long, the technology is difficult to master, and the cost of use is high, which will restrict the clinical use of wrist arthroscopy

Therefore, carpal tunnel syndrome does not have a small surgical incision and low cost and easy-to-handle surgical instruments so far.
