Pushing mechanism for minimally invasive surgical robot

Abstract

The invention discloses a pushing mechanism for a minimally invasive surgical robot, which is an end executor for a minimally invasive surgical robot, which comprises an axially feeding part and a circumferentially rotating part, wherein the axially feeding part comprises two symmetric axially feeding modules, and each axially feeding mold comprises a motor, a guide rail, a screw, a clamping module and a limiting switch; and a clamping module clamps a guide pipe or guide wire and does linear action along a guide rail through the screw, and when contacting the limiting switch, the clamping module changes movement direction. The circumferentially rotating part comprises a motor, a pair of external gear, rotating discs and a connecting rod; the front and rear rotating discs are connected by a connecting rod to form a rotating cylinder body, and the two axially feeding modules are fixed on the front and rear rotating discs respectively; and the rotating cylinder body rotates to drive the axially feeding part to rotate, and thus, the rotation direction of the guide tube or guide wire can be changed. Different guide tubes or guide wires can be clamped and pushed, and the modular design is convenient for detachment and disinfection.

Description

technical field [0001] The invention relates to a minimally invasive vascular interventional surgery robot in the field of medical equipment, in particular to a minimally invasive vascular interventional surgery robot propulsion mechanism. Background technique [0002] Traditional vascular interventional surgery is done manually by doctors, which has obvious disadvantages. For example, doctors work in the radiation environment, and long-term operation will cause great harm to the body; Long; Due to the complex operation, long operation time, doctor fatigue and unstable manual operation and other factors will directly affect the quality of operation, and then affect the quality of life of patients. [0003] In recent years, the research and development of medical robots has become more and more intensive, and there are more and more medical robots for clinical applications. In the existing technology, the propulsion principle of the minimally invasive vascular interventional ...
