Embodiment Construction

[0037] combine Figure 1 to Figure 7 Describe this embodiment, the robot of this embodiment includes a main shaft, a main shaft lifting mechanism, a main shaft rotation mechanism, a main shaft end opening and closing mechanism, and a main shaft lifting mechanism: the first motor 102 drives the lead screw 101 to rotate through the elastic pin coupling 103 , the lead screw 101 drives the nut 105 to screw together, so that the moving plate 12 realizes the lifting function on the dovetail guide rail 17 and the rectangular guide rail 16 . The moving plate 12 drives the umbrella-shaped housing 407 to move up and down, and the umbrella-shaped housing 407 drives the main shaft 401 to realize the lifting function;

[0038] Spindle rotation mechanism: the second motor 302 drives the first gear 307 to rotate, the first gear 307 meshes with the second gear 308, the second gear 308 drives the rotation shaft 301 to rotate, the third gear 305 on the rotation shaft 301 and the long sleeve 403...

Abstract

The invention provides a minimally-invasive surgery assistant robot, relates to the field of surgery robots, particularly relates to a minimally-invasive surgery assistant robot and aims to solve the problem that an existing robot hardly opens high-quality and high-accuracy wounds in minimally-invasive surgery. The robot comprises a main shaft lifting mechanism, a main shaft rotating mechanism and a main shaft tail end opening and closing mechanism, wherein the main shaft lifting mechanism is used for driving a ball screw-nut pair via a coupler by using a motor, so that a movable plate exerts the lifting function on a guide rail pair; the main shaft rotating mechanism is used for transmitting torque to a long sleeve by driving two pairs of gears via the motor, then transmitting the torque to a main shaft and enabling the main shaft to rotate; the main shaft tail end opening and closing mechanism is used for transmitting the torque via a worm and gear and a pair of gears by using the motor, lifting a turntable and stretching an inner rod so as to close a tail end surgical instrument.

Description

technical field [0001] The present invention relates to the field of medical robots, in particular to a minimally invasive surgical assistant robot. Background technique [0002] At present, minimally invasive surgical robots are represented by Da Vinci surgical robots in the United States, but Da Vinci robots are expensive, which limits the widespread development of surgical robots in China. And in the course of the operation, the doctor must pre-cut the skin, open the hole, and take the specimen. And the da Vinci robot, known as the "first brother", can only perform operations on soft tissues, but is helpless in orthopedic operations. The existing domestic surgical robots have single functions, and it is difficult to meet the needs of minimally invasive surgical techniques represented by laparoscopy in terms of accuracy. Contents of the invention [0003] The purpose of the present invention is to provide a minimally invasive surgery assisting robot. The robot is desi...
