Braking systems for robotic arms and surgical robots

Abstract

The present invention provides a braking system for a mechanical arm and a surgical robot. The braking system is installed on a column, and a mechanical arm and a weight compensation device are respectively slidably provided on the four vertical surfaces of the column. The mechanical arm is composed of The lifting system is driven to lift, wherein the brake system is an electromagnetic power-off brake and is used to brake the lifting system when the power is cut off unexpectedly. The present invention can safely transfer patients in the event of an accidental power failure without causing potential safety hazards. In addition, the mechanical arm can be easily adjusted for vertical lifting, which is beneficial to the lightweight design of the equipment.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a braking system for a mechanical arm and a surgical robot. Background technique [0002] Surgical robot, as a new development in the medical field, has received more and more attention. Therefore, its research is becoming more and more important. As the basic structure of the medical hand robot, the mechanical arm has experienced various forms and structures after a certain degree of development. [0003] Usually, the robotic arm needs to have the ability of spatial movement, because it is mainly used to determine the surgical position of the front-end instrument of the surgical robot. Among them, the mechanical arm mostly adopts passive adjustment, that is, artificially exerts force on the mechanical arm to make it move to a desired position, instead of using a motor or other driving means to realize the movement. This is because during the operation, the mechanic...

AI Technical Summary

Problems solved by technology

[0005] 1. In case of accidental power failure, the robotic arm is easy to slide down or is still in the working position, causing hidden dangers to the safety of the patient. Since the robotic arm cannot be removed, the patient cannot be transferred

[0006] 2. Manually adjusting the mechanical arm for vertical lifting requires a lot of operating force, which is a big burden for the staff;

[0007] 3. Due to the heavy weight of the mechanical arm, the gravity compensation device corresponding to the mechanical arm is also heavy, which is not conducive to the lightweight design of the equipment;

[0008] 4. Once the wire rope used to pull the mechanical arm breaks, it will easily cause safety hazards;
