Description

Polyp clamping cutter

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a polyp clamping excider.

Background

Many long pedicle polyps are often encountered during digestive endoscopic polyp strangulation treatment. The existing treatment method is that a single-ring ligation device is used, a stem of polyp is tied tightly, the polyp is tied tightly by an electric snare, and then the polyp is removed by tightening and electrifying, and finally the rest wound surface is clamped by a hemostatic clamp according to the situation. In the prior art, the single-ring ligation device is used, so that polypus is easy to be directly removed, and wound bleeding is caused. The use of electrosurgical devices for resection has the potential to cause complications such as electrocoagulation syndrome, postoperative bleeding, and the like.
