Abstract

The invention relates to a soft tissue clip, in particular to a high-stability soft tissue clip for a gastroscope. The high-stability soft tissue clip comprises a rod body and a clamp head mounted onthe rod body, wherein the clamp head is fixed to the front end of the rod body, a thumb fixing ring is mounted at the rear end of the rod body, and an index finger fixing ring and a middle finger fixing ring are arranged at positions, on the lateral side of the thumb fixing ring, of the rod body; the thumb fixing ring, the index finger fixing ring and the middle finger fixing ring are of the samestructure; the thumb fixing ring consists of an inner extension ring and an outer fixing ring, and elastic expansion rods in annular array distribution are arranged between the inner extension ring and the outer fixing ring. The high-stability soft tissue clip has the advantages that the inner extension ring can extend and retract through the elastic expansion rods, so that the high-stability softtissue clip is suitable for fingers different in thickness and has high comfort level and high stability; the problems that existing soft tissue clips on the market do not well fit fingers differentin thickness due to finger fixing rings with fixed pore diameters, have low comfort level, have extremely low stability in finger wearing especially when the pore diameters of the finger fixing ringsare ultra-large and the like are further solved.

Description

technical field [0001] The invention relates to a soft tissue clip, in particular to a high-stability gastroscope soft tissue clip. Background technique [0002] Gastroscopy is a method of medical examination and also refers to the equipment used in this examination. Gastroscopy can directly observe the real situation of the inspected part, and can further confirm the diagnosis through pathological biopsy and cytological examination of suspicious lesions. It is the preferred inspection method for upper gastrointestinal lesions. It is inserted into the stomach through a thin, flexible tube, allowing doctors to directly observe lesions in the esophagus, stomach, and duodenum, especially for minor lesions. [0003] The soft tissue is clamped under the gastroscope, and the wound is directly clamped with soft tissue clips. After the hemostasis of the wound is ensured, the gastroscope is removed, which greatly improves the success rate of the operation. [0004] However, the sof...
