Abstract

The invention relates to an automatic needle-feeding mechanism of a medical robot, which mainly comprises a support arm mechanism (1), a puncturing mechanism (2) and a puncture needle device clamping mechanism (3). The support arm mechanism (1) comprises a first end cover (11), a second end cover (12) and a box body (13), and a first transmission gear (14) and a second transmission gear (15) are arranged in the box body (13); an extending end of a rotating table (22) of the puncturing mechanism (2) is provided with a first bevel gear (23) and a second bevel gear (24) for engagement, the first bevel gear (25) and the second bevel gear (24) are integrated and are engaged for transmission; and the puncture needle device clamping mechanism (3) comprises a clamping box body (31), a rack (32), clamping teeth (33) and a chassis (34). The automatic needle-feeding mechanism of the invention has a simple structure, the surgical automation can be fully achieved, and the surgical safety and reliability can be realized. Moreover, the automatic needle-feeding mechanism is simple and easy to use, maintain and repair.

Description

technical field [0001] The present invention is based on a needle insertion mechanism of a microwave ablation robot, especially an automatic needle insertion mechanism of a medical robot capable of automatic needle insertion. Background technique [0002] Since 2006, Tsinghua University, PLA General Hospital and Beijing Institute of Petroleum and Chemical Technology have cooperated in the research of the Beijing Science and Technology Commission project "Development of Ultrasound-Guided Microwave Ablation Robot System for Liver Tumors". At present, ultrasound-guided microwave ablation therapy has been developed. Assistive Robotic Systems. However, the current medical robot is bulky, unable to adapt to the clinically limited surgical space, and does not have clinical practicability, and this robot only has the function of automatic positioning of microwave electrode needles, but does not have the function of automatic puncture. The successful design of surgical assisting rob...
