Problems solved by technology

Also, after a blockage, the presence of the stent makes it difficult to perform another ostomy
[0007] Therefore, regardless of whether balloon expansion or stent expansion is used, there is a risk of closure of the opening, resulting in poor patient outcomes

Abstract

The invention relates to an atrial shunt instrument and a stoma instrument. The atrial shunt instrument comprises a traction piece, a cutting piece, a sheathing canal and a control handle, wherein the traction piece, the cutting piece and the sheathing canal are all connected with the control handle; the traction piece is movably contained in the sheathing canal and used for pulling tissue to be cut into the sheathing canal; the control handle comprises a traction piece control assembly and a limiting piece, the traction piece control assembly controls the traction piece to be movably contained in the sheathing canal, and the limiting piece is used for locking the relative position of the traction piece and the sheathing canal; the cutting piece comprises a cutting part; and the cutting part is connected with a radio frequency power supply connector, so the cutting part is electrified to carry out electric cutting when being electrified. When the atrial shunt instrument is used for stoma shunt, a stent does not need to be implanted, and an opening can be prevented from being closed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an atrial shunt device and an ostomy device. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] Heart failure is a complex clinical syndrome of impaired ventricular filling or ejection due to structural or functional abnormalities of the heart, characterized by dyspnea and fatigue (limited exercise tolerance) and fluid retention (pulmonary congestion and peripheral edema). Heart failure is the severe and terminal stage of various heart diseases with a very high incidence and has become the most important cardiovascular disease in the world. With the advent of the aging era, the incidence of heart failure is increasing. The patient's activity tolerance is poor, the survival rate is low, repeated hospitalization is required, and the quality of life is low. [0004] H...
