Thammasat University Professor Wins Gold Medal for Innovating a ‘Medical Robotic Arm’

Report Post

Assoc. Prof. Dr. Chayanin Angthong of Thammsat University received the gold medal award for excellence from the University of Medicine and Pharmacy, Bucharest Romania for her innovation “Medical Robotic Arm” at the Inventor’s Day held by the National Research Institution in February, 2020.

This Medical Robotic Arm is a 4-jointed metal robot arm device that can lift the main arm up and down. The robotic arm is operated by an electric motor and controlled by a manual switch. The first support arm has a metal lock that can be locked and release to rotate itself. Moreover, both the first and second support arms can be extended. The joints between the second support arm and prosthesis hand can be bent, twisted, and rotated to support the appendages as needed. This robot arm is controlled by locking and releasing the metal lock on the controller. This device also has a metal base supported by 4 wheels allow it to be moved around stably.

The objectives of the invention are to create:

  1. A robotic arm device that can be used to work on in place of humans, which helps reduce injuries, and the exhaustion of personnel who have to lift and rotate the appendages repeatedly for a long time in the operating room.
  2. A robotic arm device used in place of humans, in the position that exposes to radiation during surgery.
  3. An invention that prevents accidents from dropping the appendages due to arm exhaustion. Because in the case of an accident which may cause the appendage to fall on the operating bed and cause additional injury or infection to the patients. It promotes a safe operation for the staff as well.

This innovation is funded by Thammasat University Hospital and has been tested and the results are as follow:

  1. Engineering tests have shown that the medical robot arm is strong and can support the weight up to 100 kilograms
  2. Field tests, using in volunteer cases and helping prepare the surgery for patients shown that the medical robot arm is effective in use. It helps reduce the workload of staff in the operating room. Overall, the robot arm is safe to use in place of human staff in the operating room.

However, this innovation is still in the process of requesting the approval of the petty patent by the Department of Intellectual Property.
