Tissue hemostasis clamping device

Abstract

The invention discloses a tissue hemostasis clamping device, comprising a clamp, a releasing mechanism, a drawing assembly, a handle assembly and an external sheathing canal, wherein the clamp comprises a clamping plate and a connector integrally fixed with a pull-push end of the clamping plate; the pull-push end of the clamping plate and the connector can slide back and forth in a tightening pipe, the connector is buckled with the tightening pipe by a loose-preventing mechanism; the front part of the tightening pipe is provided with a stopper; a clamping arm of the clamping plate is provided with a closing stop; the releasing mechanism comprises a pull-push pipe, wherein the front part of the pull-push pipe is connected with the connector in a manner of connection failure when the front part of the pull-push pipe bears the stress exceeding a predetermined tensile force, while the rear part of the pull-push pipe is fixedly connected with a drawing steel wire; the front part of the connection pipe is connected with the rear part of the tightening pipe by a slipknot, and the rear part of the connecting pipe is fixedly connected with a sheathing tube; and the slipknot connection of the connection pipe and the tightening pipe is relieved by a pull-push pipe through the releasing mechanism. With the adoption of the technical scheme, the device has advantages of simple and reasonable structure, stable and reliable clamping, possible repeated pre-clamping, small volume of the clamp and smooth appearance.

Description

technical field

[0001] The invention relates to a clamping device for tissue hemostasis, in particular to a clamping device for achieving the purpose of hemostasis by clamping living tissue under an endoscope. Background technique

[0002] Pathological bleeding in the gastrointestinal system, digestive system, biliary system, vascular system, and other body cavities and hollow organs is a common emergency in internal medicine. Drug treatment alone has a long course of treatment, severe side effects, and some are even life-threatening. Endoscopic surgery can achieve the purpose of hemostasis. With the development of endoscopic hemostasis technology, endoscopic application of hemostatic clips has become the first choice. In the simplest application, the clamping device for hemostasis is inserted into the deep tissue in the body through the working forceps of the endoscope. At the desired position, the edge around the bleeding tissue is grasped with the above-mentioned clamp, ...
