Combined operation device for arthroscopic carpal tunnel release

Abstract

The invention relates to the technical field of medical auxiliary equipment, in particular to a combined operation device for arthroscopic carpal tunnel release, which comprises a lens sleeve assembly and a shearing assembly, the lens sleeve assembly comprises a semi-opening sleeve, an opening included angle adjustable part is arranged at the end part of the semi-opening sleeve, and an observation window is formed in the body of the semi-opening sleeve; the shearing assembly comprises a scissor body, and the outer side face of a front-end blade of the scissor body is detachably connected with an arch-shaped check block. According to the combined operation device for arthroscopic carpal tunnel release, the opening included angle of the half-opening cannula is adjusted through the opening included angle adjustable part, the effect of opening soft tissue is achieved, meanwhile, the condition of the soft tissue can be observed through the observation window, an arch-shaped check block is arranged on the shearing assembly, and the cutting assembly is convenient to use. It is ensured that the scissor tip does not hurt surrounding extensor muscles and nerves when the carpal canal is released, and the handle at the rear end of the scissor body provides an appropriate angle for an operator through the guide arc-shaped block.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a combined operating device for arthroscopic carpal tunnel release. Background technique [0002] Carpal tunnel syndrome (CTS) is a decrease in volume or increased pressure in the carpal tunnel, resulting in compression of the median nerve in the carpal tunnel, numbness and pain in 1-3 or 1-4 fingers, and thumb abduction, abduction, and pain. A group of syndromes characterized by palm weakness and inflexible movements. At present, the treatment of CTS includes conservative treatment and surgical treatment, and the purpose of surgical treatment is to relieve the compression of the median nerve, thereby reducing the symptoms of the compression of the median nerve. Japanese scholar OKUTSU et al first reported endoscopic carpal tunnel release (ECTR) assisted by inner diameter in 1989. Comparative clinical studies found that ECTR has the advantages of quick recove...

Problems solved by technology

[0004] In order to overcome the deficiencies of the existing arthroscopic carpal tunnel release equipment with complex structure, high price, cumbersome operation and inconvenient mastery, the present invention provides a combined operating device for arthroscopic carpal tunnel release, with a half opening The casing cannula adjusts the opening angle through the opening angle adjustable part to play the role of stretching the soft tissue. At the same time, the soft tissue can be observed through the observation window. The arched stopper made of polyethylene can be detachably connected to the shearing component. block, to ensure that the tip of the scissors does not injure the surrounding extensor muscles and nerves when releasing the carpal tunnel, and the handle at the rear end of the scissors body provides a suitable angle for the surgeon through the guide arc block
