Automatic intervention device of catheter

Abstract

A conduit automatic intervention device relates to a conduit delivery mechanism. The conduit automatic intervention device solves the problems that the existing continuous mode delivery mechanism has difficult force feedback and has slippage; the motor of a batch-type delivery mechanism needs frequently positive inverted alternation. Two holding jaw fixed rails are symmetrically arranged on the outside of a first fixed rail and a second fixed rail. A dovetail at the lower end of a first double rack is matched with a dovetail groove of the first fixed rail. The dovetail at the lower end of a second double rack is matched with the dovetail groove of the second fixed tail. A first half gear and a second half gear are respectively arranged on a shaft, the two ends of which are articulated with the two holding jaw fixed rails. A first holding jaw mechanism is fixedly arranged on a first connection plate and a second holding jaw mechanism is fixedly arranged on a second connection plate. The centre line of a catheter sheath is superposed with the axle center of the first holding jaw mechanism and the second holding jaw mechanism. The axle center of a tunnel body of a tube replacing mechanism is superposed with the axle center of the first holding jaw mechanism and the second holding jaw mechanism. The conduit automatic intervention device realizes the continuous delivery of the conduit and avoids the frequency starting of the motor.

Description

A catheter automatic intervention device technical field The invention relates to a catheter delivery device, in particular to an interventional device used for automatic catheter delivery in minimally invasive interventional operations. Background technique Minimally invasive interventional surgery has been widely used in the world due to its advantages of less bleeding, less trauma, less complications, safety and reliability, and quick postoperative recovery. Catheter is the most important tool in interventional surgery. At present, catheter intervention is mainly delivered manually by doctors at the operation site. The disadvantages are: (1) The operation accuracy is not easy to grasp. Vibration will cause damage to human tissue; (2) Doctors will inevitably suffer radiation damage when operating on site. To avoid radiation, doctors need to wear heavy lead clothing. Therefore, the development trend of catheter intervention must be remote operation, that is, the doctor l...

AI Technical Summary

Problems solved by technology

The purpose of the present invention is to solve the problems of difficult force feedback and slippage in the existing continuous conveying device, while the motor needs to be frequently alternated in positive and negative directions during the operation of the intermittent conveying device, the life of the motor is short, and the catheter cannot be replaced automatically.
