Abstract

The present application relates to an interventional valve delivery system, which includes a handle assembly and a pipeline. The handle assembly includes a casing, a transmission mechanism and a runner, the transmission mechanism is arranged in the casing, and the pipeline is connected with the transmission mechanism. The shell is provided with an open part, and the opening angle of the open part in the circumferential direction of the shell is greater than 180°. The runner is installed in the open part for rotation, and the runner is connected with the transmission mechanism, which is used to drive the transmission mechanism to drive the pipeline in the axial direction. Movement to achieve admission or release of the intervening valve. In this application, by setting the open part, the runner can only perform rotational movement, and will not move axially with the transmission mechanism and the pipeline, so as to avoid the damage to the pipeline adjustment accuracy caused by the simultaneous rotation and axial movement of the runner. influences. In addition, on one side of the open part of the housing, a product axial stress relief structure is designed, so that the handle assembly of the delivery system will not bear the axial force across the single side, so as not to affect the coaxiality of the delivery system , for smoother operation.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to an interventional valve delivery system. Background technique [0002] Interventional valve system is an emerging valve replacement device. With the continuous advancement of technology, there are more and more requirements for the rapid and accurate preparation of the product, the stability and reliability of the release and recovery of the product in the body, and the operational stability of the supporting delivery system. higher requirements. [0003] In terms of the design of the delivery system supporting the valve system, most of them are small-sized and semi-closed designs, which are often deficient in the accuracy, comfort and stability of the operator's operation. The more common structural design of the conveying system in the prior art includes an electric control handle and a movable large wheel mechanical control handle, both of which have some de...
