| Summary: | 碩士 === 國立中央大學 === 機械工程研究所 === 97 === Laparoscopy surgeries are being widely used due to their significant advantages over traditional open surgies. However, the surgeons have to face several difficulties never experienced in open surgeries such as poor depth perception, limited field of view.Laparoscopy surgery simulation system can provide a no danger and low medical resources consume training platform.Yet, few research can effective assess the construct validity of Laparoscopy surgery simulation system.
In this study we use real surgical instrument to develop a system that can measured force, displacement and time.Using the proposed system, two sets of animal experiments were conducted in an operating room to measure force-displacement and force-time of pig liver.we also add some voice that can help user in surgical training.
We use Visual Basic 2005 to develop the system which includes test platform control and acquisition operating interfaces and system control interfaces, we also use Microsoft Access to establish force feedback、time and displacement database.
The study adopt force feedback experiment and voice feedback experiment in order to verify the system, the results show that voice feedback have more operation accuracy than without force feedback. It also shows that voice feedback has assist in Laparoscopy surgery training. The reproducibility of the system reality assessment was analyzed using the intraclass correlation(ICC) approach.
