Problems solved by technology
[0002] Surgery usually uses valve edge-to-edge suture and other surgical methods to treat mitral valve regurgitation. During minimally invasive treatment, the valve edge-to-edge suture will be completed with the help of a valve clamp. During the operation, if the valve clamp is accidentally opened Or if the valve clip falls off after implantation, it will lead to the failure of the operation, and in severe cases, it will endanger the life and health of the patient.

Embodiment Construction
[0041] The technical solution in this application will be described in further detail below in conjunction with the accompanying drawings.
[0042] In order to understand the technical solution in this application more clearly, a valve clamp and its use are briefly introduced first.
[0043] Surgery usually uses valve edge-to-edge suture and other surgical methods to treat mitral valve regurgitation, but this type of surgery has complex surgical procedures, high surgical costs, high patient trauma, high risk of complications, long hospital stay, and patient recovery process. Pain and other defects.
[0044] There is a minimally invasive treatment device, which is based on the principle of valve edge-to-edge surgery. The valve clamp is delivered to the mitral valve through the interventional catheter, and then the anterior part of the mitral valve is grasped simultaneously by the relative opening of the clamp. Leaflets and posterior leaflets, thereby pulling the leaflets towar...

The embodiment of the present application relates to a valve clamping device and a valve repair system. The valve clamping device includes a fixed base, a through hole passing through the fixed base, a clamping part provided on the fixed base, a first drive shaft and an adjustable Disassemble the second drive shaft connected to the first drive shaft, the card slot provided on the first drive shaft and the push piece, the first end of the first drive shaft passes through the through hole and then is rotatably connected to the clamping part, It is used to drive the clamping part to switch between the locked state and the free state. The push piece includes an outer frame and an elastic piece arranged on the outer frame. The outer frame is arranged on a fixed base, and the elastic piece extends into the through hole. The sheet can abut against the card slot. The valve repair system includes the above-mentioned valve clamping device. The valve clamping device and the valve repair system disclosed in the embodiments of the present application increase the locking force by adding a mechanical locking structure to improve stability and ease of operation.
Description
technical field [0001] The present application relates to the technical field of medical devices, in particular to a valve clipping device and a valve repair system. Background technique [0002] Surgery usually uses valve edge-to-edge suture and other surgical methods to treat mitral valve regurgitation. During minimally invasive treatment, the valve edge-to-edge suture will be completed with the help of a valve clamp. During the operation, if the valve clamp is accidentally opened Or the valve clip falls off after implantation, which will lead to operation failure, and will endanger the life and health of the patient in severe cases. Contents of the invention [0003] The embodiments of the present application provide a valve clamping device and a valve repair system, which increase the locking force by adding a mechanical locking structure to improve stability and ease of operation. [0004] The above-mentioned purpose of the embodiment of the present application is ac...
