Stenosing tenosynovitis surgical tool with elastic cutting edge

Abstract

The invention is suitable for the technical field of tenosynovitis surgical equipment, and provides a stenosing tenosynovitis surgical tool with an elastic cutting edge. The stenosing tenosynovitis surgical tool comprises a knife head, a knife holder and a handle; the bottom part of the knife head is fixedly provided with a knife handle; the knife handle is movably installed in the knife holder; an elastic device is also arranged in the knife holder; the elastic device includes an elastic diaphragm with a cavity inside; an upper sealing flange and a lower sealing flange are respectively fixedto openings of two ends of the elastic diaphragm through connecting pieces; the upper sealing flange is connected with a fixing plate arranged at the bottom part of the knife handle; and the lower sealing flange is installed in the knife holder through a mounting plate. The stenosing tenosynovitis surgical tool has the beneficial effects: the energy of tremble caused by the problems including tension of a medical worker can be better absorbed, thus guaranteeing that the entire knife head is in a stable state; and meanwhile, due to limiting of the knife holder, the knife head cannot sway left and right, thus guaranteeing the using effect.

Description

technical field [0001] The invention relates to a tenosynovitis operation device, in particular to a constriction tenosynovitis operation tool with an elastic blade. Background technique [0002] Constrictive tenosynovitis is mainly due to trauma or repeated friction of the tendon, resulting in hyperplasia of the inner layer of the tendon sheath, fiber adhesion, and even the formation of fibrocartilage lesions into a narrow fibrocartilage ring, thereby affecting the normal activities of the tendon. [0003] At present, the treatment methods for tenosynovitis are mainly divided into conservative treatment and surgical treatment. Surgical treatment usually uses common surgical blades for surgical operations, and common surgical blades can cause secondary trauma to patients because of the shaking of the blades during the treatment of stenosing tenosynovitis. Contents of the invention [0004] The purpose of the embodiment of the present invention is to provide a constrictive...

AI Technical Summary

Problems solved by technology

Surgical treatment usually uses ordinary surgical blades for surgery. Ordinary surgical blades will cause secondary trauma to patients due to the vibration of the blade during the treatment of stenosing tenosynovitis.
