Abstract

The linear snare applied under the digestive endoscopy comprises a snare device and an operation assembly, the snare device comprises a resin clamp, a spring, a connecting hole, a metal wire and a baffle, the spring is installed on the resin clamp, the resin clamp is provided with the connecting hole used for fixing the metal wire, and the baffle is arranged at the end of the resin clamp; the operation assembly comprises a snare device base, a resin clamp operation rod, a resin clamp loosening rod, a resin clamp operation rod handle and a metal wire operation handle. By means of the device, the defects of a traditional snare can be overcome, and when the resin clamp is fixed to the intestinal wall mucosa, the other movable end of the metal wire surrounds the bottom of the polyp through the metal wire operation handle; after being tightened, the resin clamp and the metal wire connected with the resin clamp form a closed loop, a polyp as large as possible or a polyp with an asparagus position can be cut off under an endoscope under the electrified condition, the operation is convenient and fast, the operation efficiency is improved, and the operation safety of a patient is also improved.

Description

technical field [0001] The invention relates to the medical field, in particular to a wire snare used under digestive endoscopy. Background technique [0002] At present, the most widely used snare in the market are all coil-shaped snare, which are more convenient when relatively small polyps or polyp positions are easy to snare. [0003] However, the existing snare has the following defects: [0004] 1. When encountering large polyps, the diameter of the snare needs to be adjusted according to the size of the polyp, which is not convenient enough; [0005] 2. When the polyp is located at the corner of the digestive tract or in a more complicated position, it often occurs that no matter how to adjust the angle of the snare or change the direction of the endoscope, the polyp cannot be completely snare or can not be completed in a short time. , which greatly increases the time of endoscopic polyp resection, reduces the surgical efficiency, and also increases the risk of anes...
