Research Abstract |
It is well known that surgeons are required to learn many skills and to take many medical training for diagnosis and surgery. Traditionally, the medical doctors have been learned from the anatomy of patients, dead body, animals and simple abdomen. In recent years, medical training system based on the VR (Virtual Reality) technologies became popular for remarkable development of the computer and graphic technologies. In this research, we have developed surgical simulators for medical training as follows : (1) Development of injection training system for central venous catheter placement and lumbar puncture (2) Laparoscopic surgery training system (3) Laparoscopic surgery support system used projection image (4) Development of spectral endoscopes In order to archive higher reality for central venous catheter placement and lumbar puncture training, we have developed image overlay system with head tracking using infrared LEDs. In the training system of laparoscopic surgery for cholecystectomys, real time deformation of liver named beam model was introduced and this proposed model was implemented for real time deformation by two forceps controlled with two PHANToM. We also developed the laparoscopic surgery support system used projection display. In this system, surgeon can perceive laparoscopic image of organ as 3D image by using a stereo projector and the system can correct the shape of the projected image in real time by acquiring the shape of abdominal surface and the position of the surgeon's head. On the spectral endoscopes, it became possible to reproduce spectral image and diagnose various kinds of diseases by using spectral information.
