Intervention system for delivering valve clip

Abstract

The invention relates to the field of medical instruments, in particular to an intervention system for conveying a valve clip. The system comprises a fixed support, a first conveying module, a second conveying module and a third conveying module; the first conveying module comprises a first control body and a first conveying pipe, and the second conveying module comprises a second control body and a second conveying pipe; the first conveying module and the second conveying module are each provided with a rotary locking mechanism, the rotary locking mechanisms are fixed to the fixing supports in a matched mode, and the rotary locking mechanisms can lock the rotation angle in real time. The first conveying pipe comprises a first pipe body and a bent section; the second conveying pipe comprises a second pipe body, a self-adaptive section, a maintaining section and a bending adjusting section; the self-adaptive section and the bending section are axially overlapped; the retaining section and the bending section are axially arranged in a staggered mode or part of the retaining section and the bending section are axially arranged in an overlapped mode, the third conveying module comprises a third control body and a third conveying assembly, and part of the third conveying assembly is arranged in the second conveying pipe.

Description

Technical field [0001] The present application relates to the field of medical devices, and more particularly to an interventional system for delivering a valve clip. Background technique [0002] Mitral valve anatomy is complex, including leaflets, annulus, tendonis and nipple muscles, and maintenance of left and right ventricular functions, respectively. Any disease affects the structural completeness and function of the leaves, the annulus, tendonis, the nipple muscle and left ventricle may result in severe mitral regurgitation, mr), which can cause left ventricular failure and pulmonary hypertension. , Ventricular fibrillation, stroke and death. According to the latest epidemiological survey data such as Western developed countries in the United States, the incidence of the first position of the first position of the first position of the first position is the second-pointed reflux. At present, although there is no authoritative epidemiological survey data, with the advent of...

Problems solved by technology

[0008] One of the purposes of this application is to overcome the deficiencies of the prior art, and to provide a valve delivery system for problems such as the inability of the delivery system to lock the bending angle in real time during the rotation operation and the delivery catheter can only meet the one-way bending angle. interventional system
