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 an ostomy instrument. The atrial shunt device includes a pulling member, a cutting member, a sheath and a control handle, and the pulling member, the cutting member and the sheath are all connected to the control handle; the pulling member is movably accommodated in the sheath , used to pull the tissue to be cut into the sheath tube; the control handle includes a puller control assembly and a stopper, and the puller control assembly controls the puller to be movably accommodated in the In the sheath tube, the stopper is used to lock the relative position of the puller and the sheath tube; the cutting part includes a cutting part; the cutting part is connected with the RF power connector, so that The cutting part is charged to perform electric cutting. Using the atrial shunt device for stoma shunt does not require implantation of a stent and can avoid closure of the opening.

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...
