A congenital heart disease occluder recovery forceps

Abstract

The invention provides congenital heart disease occlusion device recovery forceps comprising a control steel wire and a movable sleeve arranged on the outer side of the control steel wire. The end of the movable sleeve is provided with a flap-type clamp head used for clamping the projection of the occlusion device, the flap-type clamp head is composed of three or more than three clamp flaps, the outer sides of the lower ends of the clamping flaps are hinged to the end of the movable sleeve, the upper end of the control steel wire extends out of the front end of the movable sleeve and is connected to the clamping flaps through a plurality of links hinged to the upper end of the control steel wire, and one ends of the links hinged to the other end of the control steel wire are hinged to the inner walls of the clamping flaps. The forceps are simple in structure, the position of an occlusion device can be judged more conveniently through planar image of a minimally invasive surgery through the multi-flap clamping head by the controllable head bending technology, the occlusion device in a blood vessel can be recovered directly, the angle of the multi-flap clamping head can be adjusted through the manner of the hinging the movable sleeve to a fixed sleeve, and the occlusion device on the periphery of the recovery forceps can be clamped more conveniently during the surgery.

Description

technical field [0001] The invention relates to a congenital heart disease occluder recovery forceps. Background technique [0002] Interventional closure of congenital heart disease such as atrioventricular septal defect and patent ductus arteriosus is a routine technique, such as figure 1 Shown is a schematic diagram of the structure of the occluder, which mainly includes a body 100 and a protrusion 101 arranged at the end of the occluder, and the middle part of the protrusion 101 is provided with an internal thread. One of the common complications of this technique is the fall-off of the occluder, which is a dangerous complication and usually requires surgery to remove the fall-off occluder. There is currently no special instrument for interventional methods, and it is very difficult to remove the fall-off occluder. Contents of the invention [0003] The present invention improves the above problems, that is, the technical problem to be solved by the present invention ...

AI Technical Summary

Problems solved by technology

[0003] The present invention improves the above problems, that is, the technical problem to be solved by the present invention is that the removal of the existing occluder requires surgical removal, and there is no special instrument for the intervention method at present, and it is very difficult to remove the fallen occluder
