Description

Special surgical needle knife for tenosynovitis strictus

Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to a special operation needle sword of flexor stenosing tenosynovitis.

Background

Stenotic tenosynovitis is a common disease of the tendon sheath, and is clinically manifested by finger bounce with obvious pain and severe patients suffering from finger flexion and dare. At present, the treatment method of stenosing tenosynovitis mainly comprises conservative treatment and surgical treatment, and when the surgical treatment is carried out, a needle knife is widely adopted.

The main part of traditional needle sword is sharp needleknife main part, and the end sets up flushes a mouthful cutting edge, and this kind of structural style's needleknife is when using, and the cutting edge that levels the mouth lacks the guard action to the tendon, harms the outer soft tissue of tendon sheath easily, and is thorough inadequately to the pine of tendon sheath. In order to solve the problem, the industry is also actively seeking a solution, and the knife edge is improved, and a new needle knife such as a sickle knife, a V-shaped needle knife and the like appears, but the needle knife has the following defects when in treatment:

1. when the traditional needle knife is used, the penetration depth of a needle head is not well determined, the experience and judgment of an operator are required, the requirement on the operator is high, the good knife control capability is required, otherwise tendons are easily damaged, and the operation difficulty is very high for a beginner;

2. no matter the knife edge is flush, or hook sickle or V-shaped needle knife, because the main body of the needle knife is straight, the flat pushing can not be realized during the operation, the knife edge part is pushed deeper in the human tissue after the needle is inserted, and the tendon of the human body is flat, so the tendon is easily damaged when the knife edge is pushed deeper;

3. the width of the blade parts of the hook sickle and the V-shaped needle knife is larger, so that the incision is larger, and the risk of tendon injury is also existed.
