Clamping and rotating device and interventional operation robot

Abstract

The invention provides a clamping and rotating device and an interventional surgical robot. The clamping and rotating device comprises two oppositely arranged clamping pieces and a clamping driving assembly for driving the two clamping pieces to move relatively so as to clamp an instrument; a rotating mechanism sequentially comprises a rotating driving assembly and a rotating transmission assembly which is in driving connection with the rotating driving assembly and can output rotating action along the instrument delivery direction; the rotating driving assembly and the rotating transmission assembly are internally provided with a mounting channel penetrating along the instrument delivery direction, and an instrument is delivered to the position between the two clamping pieces from the interior of the mounting channel; and the rotating transmission assembly is in transmission connection with a clamping mechanism so as to drive the clamping mechanism to rotate. According to the clamping and rotating device disclosed by the scheme of the invention, clamping and twisting of the instrument are achieved at the same time, the bionics principle is met, and twisting precision is high.

Description

technical field [0001] The present application relates to the technical field of vascular interventional surgery auxiliary equipment, in particular to a clamping and rotating device and an interventional surgery robot. Background technique [0002] From 2010 to 2018, the use of cardiac stents in percutaneous coronary intervention (hereinafter referred to as “PCI”) surged year by year in China. In 2019, the number of coronary interventional PCI operations in China was close to 1 million. In the future, with the intensification of my country's population aging, this number will maintain a relatively high growth rate. For now, China's vascular interventional field is still in a stage of rapid development, and there is a lot of room for import substitution and innovative research and development. [0003] In recent years, vascular interventional therapy technology has developed rapidly. Under the guidance of medical images, doctors send special precision instruments into the hu...

Problems solved by technology

At present, there are certain problems in vascular interventional treatment methods. Doctors are exposed to radioactive radiation such as X-rays and CT for a long time, which has caused harm to the health of doctors; Fatigue, factors such as fatigue and unstable manual operation will seriously affect the quality of surgery, and only experienced doctors can perform it. Therefore, robot-assisted vascular interventional surgery technology is an important direction for the development of vascular interventional therapy

[0004] When the robot for vascular interventional surgery delivers the catheter / guide wire, it needs to rotate the catheter / guide wire when it encounters a vascular bifurcation so that it can pass smoothly. Affect the efficiency of operation
