Control handle, valve suturing device and valve suturing system

Abstract

The invention provides a control handle, a valve suturing device and a valve suturing system. The control handle is applied to the valve suturing device and comprises a shell, a rotating mandrel module and a plurality of action control modules, wherein the rotating mandrel module extends in the shell in the axial direction and partially extends out of the shell, the action control modules are arranged on the shell, each action control module comprises an operation piece, and all the operation pieces are located on the front surface, facing an operator, of the shell; the rotating mandrel module is rotationally connected with the shell and the action control modules, so that the rotating mandrel module can rotate by any angle relative to the shell and the action control modules, and the operation pieces face the operator all the time. In the whole operation process, all the operating pieces face the operator all the time, on one hand, the operator can conveniently and rapidly execute various operations on all the operating pieces, on the other hand, when the far end of the valve suturing device needs to be rotated to clamp different valve leaflets, only the rotating mandrel module needs to be rotated, the control handle and the whole instrument do not need to be rotated, and operation is more convenient.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a control handle, a valve suturing device and a valve suturing system. Background technique [0002] The tricuspid valve is a one-way valve between the right atrium and the right ventricle. Its anatomical structure includes the valve ring, valve leaflets, chordae and papillary muscles. The valve leaflets are composed of anterior valve, posterior valve and septal valve. The attachment edge of the valve leaflets and the free edge of each leaflet are connected to the papillary muscle by the chordae. The normal tricuspid valve can ensure the flow of blood from the right atrium to the right ventricle, and when the right ventricle contracts and squeezes the blood in the room, the tricuspid valve closes, and the blood will not flow back into the right atrium, so that the blood of the right ventricle is discharged from the pulmonary valve. into the pulmonary artery.

However, surgery has the disadvantages of large trauma, slow recovery, and high risk

In recent years, the treatment of tricuspid regurgitation through minimally invasive intervention has gradually become a research hotspot. However, the handles of the existing minimally invasive interventional valve repair instruments usually have to be held by the operator, and the control parts are scattered in different positions of the handle, such as the front. And side, inconvenient operation, etc., especially when it is necessary to rotate the distal end of the instrument so that the distal end of the instrument clamps different leaflets and implants sutures for the corresponding leaflets, it is often necessary for the operator to rotate the handle and the whole instrument to Make the distal end of the instrument rotate, and after the rotation is in place, you need to keep the handle in the current state (some control parts may have been rotated to the side or back of the handle) and then operate each control part, which makes the operation more inconvenient and prolongs the operation time
