Problems solved by technology

In surgery, minimally invasive surgery has a small working space, but requires robots to be more dexterous and have higher positioning accuracy, which is difficult for commonly used surgical robots.
In addition, the working space of the brain surgery robot used for brain surgery is spherical. The configuration of the commonly used brain surgery robot is mostly joint type. The series structure makes each arm affected by gravity, which reduces the reliability of the robot. sex

Abstract

A surgical robot comprises a support, a linear movement unit, a first rotation joint, a first connecting rod, a second rotation joint, a second connecting rod, a third rotation joint, a third connecting rod and a terminal rotation joint and include a movement degree of freedom and five rotation degrees of freedom. Rotation axes of a fourth rotation joint and a fifth rotation joint of the terminal rotation joint are orthogonal, so that after the first rotation joint, the second rotation joint and the third rotation joint of the surgical robot are adjusted in place, the terminal rotation joint further can rotate flexibly, and flexibility of the surgical robot is high. Rotation axes of the first rotation joint and the second rotation joint of the surgical robot are perpendicular to the ground, influence to the surgical robot due to gravity can be reduced, and the reliability of the surgical robot is improved.

Description

【Technical field】 [0001] The invention relates to a medical device, in particular to a surgical robot. 【Background technique】 [0002] With the rapid development of computer and microelectronic technology and medical science, medical robots with various purposes are being used more and more widely in the medical field. At present, research on medical robots mainly focuses on surgical robots, rehabilitation robots, nursing robots and micro-robots. In surgery, minimally invasive surgery has a small working space, but requires robots to be more dexterous and have higher positioning accuracy, which is difficult for commonly used surgical robots. In addition, the working space of the brain surgery robot used for brain surgery is spherical. The configuration of the commonly used brain surgery robot is mostly joint type. The series structure makes each arm affected by gravity, which reduces the reliability of the robot. sex. 【Content of invention】 [0003] Based on this, the p...
