A Novel Robot Structural Design for Surgical Applications

總結

A novel robot structural design is invented for surgical applications. Drilling and instrument insertion are common surgical procedures working on a spatial line. A robot with 7 joints (2 sliding joints and 5 revolute joints) is designed for various surgical applications. The large number of joints can provide the robot with adequate degrees of freedom so that obstacles can be avoided when the drilling axis or instrument insertion axis is difficult to reach in some complicated surgeries.

The radial sliding joint is the key novelty of this newly designed robot. The robot arm is allowed to move radially around the human body axis during surgery. The most suitable workspace can be provided for various surgical applications. In addition, with 7 degrees of freedom, the robot is able to perform surgical instrumentations in any direction and position on patients safely within the working environment with excellent dexterity.

With this novel structural design of the surgical robot arm, the stability and repeatability of the robot arm, combining with human dexterity and quick decision making, the accuracy and precision of the existing computer assisted surgical system are greatly improved. Surgeons can now perform surgical procedures with higher precision and predictable clinical outcomes.

Advantages and improvements over existing technology

(1) Designed according to the morphological consideration of the human body. (2) Better dexterity to deal with various surgical procedures that require multi-directional surgical targeting. (3) More compact size and better rigidity in the same workspace (4) Allows smooth manipulation by the surgeons for both manual and automatic control.
