Abstract

The invention provides a transcatheter valve conveying system and a handle thereof. The transcatheter valve conveying system handle comprises a main part and a control part disposed on the main part. The control part comprises a push-and-pull control portion comprising a screw and a push-and-pull member for pushing and pulling the screw; a rotation control portion comprising a fitting piece matched with the screw and a rotating member for rotating the fitting piece, wherein the rotating member can drive the screw through the fitting piece when the fitting piece is cooperated with the screw; and a transformation portion for enabling the fitting piece to be cooperated with or separated from the screw According to the transcatheter valve conveying system handle, accurate operation and rapid operation of the transcatheter valve conveying system can be simultaneously achieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a transcatheter valve delivery system and a handle thereof. Background technique [0002] Because transcatheter valves do not require thoracotomy like surgery, they have the advantages of less trauma and faster recovery. In recent years, as a new technology, they have been favored by doctors. Transcatheter valves are mainly delivered through a delivery system. Before implantation, the valve needs to be installed on the delivery system. During the implantation process, the valve needs to be delivered to the lesion site through the delivery system. [0003] Currently used transcatheter valve delivery systems generally include two types, one is to load the valve on the outside of the distal end of the delivery system catheter, and the valve can be pressed on the outside of the catheter by a compression device during loading. It is a balloon, which can be expande...
