Control handle of catheter pusher

Abstract

The invention relates to the field of medical apparatuses and instruments, in particular to a control handle of a catheter pusher. The control handle of the catheter pusher comprises a shell, a handle control circuit board, an advancing and retreating control unit, a rotation driving unit, a bending driving unit, advancing and retreating keys, a knob and a shifting part. The advancing and retreating keys are connected with the advancing and retreating control unit, the knob is connected with the rotation driving unit, and the shifting part is connected with the bending driving unit. The advancing and retreating control unit, the rotation driving unit and the bending driving unit are all connected with the handle control circuit board, the handle control circuit board is connected with a connector to control the advancing and retreating keys, the knob and the shifting part so as to transmit catheter motion control instructions to motor control circuits in the catheter pusher. The motor control circuits drive corresponding motors to rotate so as to realize advancing, retreating and rotating of a catheter and bending of the end of the catheter. Therefore, advancing, retreating and rotating of the catheter and bending of the end of the catheter can be controlled precisely and stably by a doctor while traditional operation feels can be reserved to realize inheritance of traditional operation experience, and operating difficulty is lowered.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a control handle of a catheter pusher. Background technique [0002] At present, minimally invasive vascular interventional surgery MIS (Minimally Invasive Surgery) has the advantages of less bleeding, less trauma, and faster postoperative recovery, and has been widely used in the world. In traditional vascular interventional surgery, doctors work in the X-ray environment for a long time, causing great harm to the body; manual intubation requires high skill and complicated operation, and doctors are prone to fatigue; manual catheter control is difficult, and misuse can easily cause damage to blood vessels. affect the quality of surgery. Introducing robot technology into vascular interventional surgery, using the advantages of high precision, high stability, simple operation and remote operation of robots, can solve the above problems well. [0003] In the existing mobile phon...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a high-precision, high-stability control handle of a catheter pusher to solve the problem that it is difficult for doctors to retain the traditional operating feel when operating the main control end of the existing vascular interventional surgery robot, so that Doctors inherit traditional surgical experience and perform operations better
