Problems solved by technology

Most of the existing control handles are controlled by mechanical methods. With the development of interventional devices, more requirements are put forward for the functions of interventional devices. The functional modules are usually implemented by their own independent drive modules, which makes the control handle transmission relatively complicated, and the overall size is large, which is not conducive to the operation of the surgery

Embodiment Construction

[0111] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0112] It should be noted that when a component is referred to as being "connected" to another component, it can be directly connected to the other component or an intervening component may also exist. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a co-existing centered component.

[0113] It should be noted that the terms "proximal" and "distal...

Abstract

The present application discloses a hydraulic delivery system for interventional instruments, comprising a plurality of pipes arranged coaxially from the inside to the outside, and a control handle for driving the relative movement of the plurality of pipes, and the distal ends of the pipes are used to cooperate with each other to operate the intervention The instrument, the proximal end of each pipe is connected to the control handle, and the relative movement of each pipe is driven hydraulically at the control handle, and the radial gap between the two adjacent pipes in the radial direction is the exhaust gap, and the interventional instrument A hydraulic drive circuit in the delivery system communicates with the vent gap for performing venting. The interventional device delivery system of the present application adopts a hydraulic drive mode, which is more convenient to operate, and can realize auxiliary functions such as exhausting as required.

Description

technical field [0001] The present application relates to the field of medical devices, and in particular, to a delivery system for delivering interventional devices into the body. Background technique [0002] The interventional device delivery system generally includes a control handle arranged at the proximal end, i.e., the operator's side, a number of slender tubes that slide and nest inside and outside, the proximal end of each tube is the control end and is connected to the control handle, and the distal end of each tube is the work piece. The control handle can generally be provided with sliding or rotating parts, and then drive the relative movement between the tubular parts in the axial direction. Most of the existing control handles are mechanically regulated. With the development of interventional devices, more requirements are put forward for the functions of interventional devices. For example, the delivery system needs to realize the functions of valve release,...
