Problems solved by technology

[0005] Because the needle knife is operated under relatively "blind vision", it is necessary to repeatedly detect the lesion during the puncture process. Because the small needle knife in the prior art lacks edge protection measures, it is easy to cause

Abstract

The invention discloses a tenosynovitis scalpel component, including a knife body, in hollow tube shape; a knife head, fixedly arranged on the top of the knife body, wherein the knife head has a firstblade and a knife back, and the first blade is arranged on the side of the knife head near the knife body and the knife back is arranged on the knife head far from the knife body; a protective innercore, wherein the outer diameter of the protective inner core is no larger than the inner diameter of the knife body; and the protective inner core is arranged in the knife body and can move along thedirection defined by the knife body. One end of the protective inner core has a holding groove to accommodate the first blade. The tenosynovitis scalpel componentcan not only achieve minimally invasive release of tendon sheath, but also protect the surrounding soft tissue to the maximum extent in the operation process, avoiding serious injury of vascular and nerve. In addition, the tenosynovitisscalpel component is simple to make and easy to operate, and can effectively improve the defects in the current 'blindness' operation of a needle knife.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a tenosynovitis scalpel assembly. Background technique [0002] The tendon sheath is divided into a fibrous layer and a synovial layer. The fibrous layer is located in the outer layer and is formed by the thickening of the deep fascia, which restrains the sliding of the tendon. The synovial layer is located in the tendon fiber sheath and is a double-layered cylindrical sheath. There is a small amount of synovial fluid between the layers, which lubricates and nourishes the tendon. The inner layer of the entire synovial sheath is wrapped on the surface of the tendon, and the outer layer is attached to the inner surface of the tendon fiber sheath, thereby forming a closed and potential gap—the synovial cavity. Due to repeated friction and strain of the hands or the influence of systemic diseases, local tendon sheath tissue ischemia, edema, inflammation, local tendon sheath hyperpl...
