Intelligent spine minimally invasive surgery robot

Abstract

The invention provides an intelligent minimally invasive surgery robot for the spine, which includes a bracket, a linear motion joint fixed on the bracket, and a swing joint, a rotary joint, a pitch joint, a linear fine-tuning joint, and a terminal rotary joint sequentially connected to the linear motion joint; the swing Joints and swing joints, swing joints and swivel joints, pitch joints and swivel joints are all fixedly connected by connecting rods; linear fine-tuning joints are fixed on pitch joints; terminal rotary joints are fixed on linear fine-tuning joints; The joints are driven to move according to a preset planned path by a driving mechanism arranged inside each joint and connected to the control system of the surgical robot. The invention realizes the control of multiple degrees of freedom of the surgical robot, linear feed, swing, rotary motion, pitch motion and linear fine-tuning motion, ensures that the robot can be adjusted to any position within the working range, satisfies any posture during work, and realizes surgery Accurate positioning and precise operation requirements.

Description

technical field [0001] The present invention relates to the technical field of auxiliary operation machinery for medical surgery, in particular to an instrument used in minimally invasive spinal surgery, in particular, an intelligent robot for minimally invasive spinal surgery. Background technique [0002] In the traditional pedicle screw internal fixation operation, in order to accurately implant the pedicle screw into the human body, it is necessary to peel off the muscles on the facet joints and transverse processes, which will damage the surrounding nerves and soft tissues of the lumbar spine. During the operation, the three-dimensional image cannot fully expose the surgical field of view, and it is necessary to use the automatic spreader for a long time to pull the muscles, further increasing the area of ​​radiation exposure, causing secondary damage to the nerves and soft tissues on both sides of the patient, and drilling nails manually It is difficult to ensure the o...
