Lifting system for robotic arm and surgical robot

Abstract

The invention provides a lifting system and a surgical robot for a mechanical arm. The lifting system includes: fixed pulleys, each fixed pulley is installed on the top of each vertical surface of the column; moving pulleys, every two moving pulleys are installed on the same vertical surface Below the fixed pulley on the surface, and the movable pulley is linked with the mechanical arm; the rope head seat, every two rope head seats are installed on both sides of the fixed pulley on the same vertical plane; the steel wire rope, one end of the two steel wire ropes passes The fixed pulleys are respectively wound on the two movable pulleys and finally connected with the rope head seat, and the other ends of the two steel wire ropes are connected with the weight compensation device. In the lifting system for the mechanical arm, the rope head seat is always tightened on the wire rope. The invention can easily adjust the mechanical arm to carry out vertical lifting; it is beneficial to the lightweight design of the equipment; it will not cause safety hazards; and patients can be safely transferred in case of accidental power failure.

Description

Technical field [0001] Technical Field The present invention relates to medical devices, and more particularly to a hoist system for a surgical robot manipulator. Background technique [0002] Surgical robot as a new development in the field of medical discovery, has been more and more attention, therefore, studied also becomes more important. As the infrastructure of medical hand robot manipulator appeared in a variety of form and structure after a certain degree of development. [0003] Typically, the robot arm requires space exercise capacity, because it is mainly used for the surgical instrument distal end position of the surgical robot is determined. Wherein the manipulator use more passive adjustment, i.e. artificial force is applied to the robot arm, it is moved to a desired position, instead of using a motor or other drive means to effect movement. This is because during surgery, the robot arm will be in a locked state, locking is performed by a motor failure and the like...

AI Technical Summary

Problems solved by technology

[0005] 1. Manually adjusting the mechanical arm for vertical lifting requires a lot of operating force, which is a big burden for the staff;

[0006] 2. 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;

[0007] 3. Once the wire rope used to pull the mechanical arm breaks, it will easily cause safety hazards;

[0008] 4. 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
