Challenges in Computer Aided Surgery Researches: Revisiting JSPS Research for the Future Program “Development of Surgical Robotic Systems”

Ichiro Sakuma, Professor

School of Engineering, The University of Tokyo

From 1999 to 2004, the author participated in the JSPE Research for the future program “Development of Surgical Robotic Systems” and served as the project leader of one sub-project from 2003 to 2004. In the project, laparoscopic manipulator “Naviot” was commercialized as the first surgical robot system in Japan. In addition, we have developed prototypes of a compact master slave surgical master-slave manipulator system, a laser guidance system for needle insertion in orthopedic surgery, fraction reduction robot, surgical navigation system based on multi-modal image registration, and various surgical devices such as laser surgical device integrated in a compact electronic endoscope. When we summarized the project, various challenges were proposed. They include:

  1. Reduction of size of master slave manipulator system and more dexterity of forceps manipulator
  2. Surgical robot that takes the soft tissue biomechanics in orthopedic surgery
  3. Application of deformable organ models based on biomechanics to deformable registration in surgical navigation system for soft tissue. 
  4. Use of molecular imaging information for surgical navigation and surgical robot control
  5. Integration of various energy device ad drug delivery system with surgical robots

Significant progress has been made in the field of computer aided surgery and surgical robotics. Some of the challenges we raised in 2005 have been already solved and clinically practical systems have been realized. On the other hand, some of the problems remain unsolved. Although the novel methods for solution have been introduced such as machine learning algorithm, I believe that it is worth revisiting the discussion we had after the project to redesign the research strategy in computer aided surgery. We must also watch the progress of life sciences that enables innovation of therapies.
