Abstract

The invention discloses an auxiliary robot for tumor puncture of four degrees of freedom, and belongs to the technical field of surgical instruments. The robot comprises a needle inserting device, a first swing drive device, a second swing drive device, a first parallel moving drive device and a second parallel moving drive device. The needle inserting device is used for finishing puncture actions, the first swing drive device is used for driving the needle inserting device to swing around Y axis, the second swing drive device is used for driving the needle inserting device to swing around X axis, the first parallel moving drive device is used for driving the needle inserting device to move in parallel along the X axis, and the second parallel moving drive device is used for driving the needle inserting device to move in parallel along the Y axis. By utilizing the robot, the automation and intelligence of mechanical needle inserting can be achieved, the surgery process is standardized,the influence of human and experience factors is reduced, the working strength of physicians is reduced, the working efficiency of the physicians is improved, and the accuracy and success rate of thesurgeries are improved.

Description

technical field [0001] The invention belongs to the technical field of surgical instruments, in particular to a four-degree-of-freedom tumor puncture assistant robot. Background technique [0002] At present, only 20% of patients with liver cancer can be surgically resected. As a modern minimally invasive treatment for liver cancer, acupuncture treatment for liver cancer has a good therapeutic effect that general liver cancer resection does not have. , minimally invasive, short recovery time and other advantages, so it is widely used in tumor treatment, detection and other fields. However, the currently known puncture mainly depends on the doctor's surgical skills, and the accuracy and success rate of puncture completely depend on the doctor's experience, and it is difficult to overcome the deviation caused by factors such as shaking. At the same time, due to the limitations of the equipment, it is difficult to accurately execute the predetermined trajectory, resulting in r...
