While endoscopic surgery has frequently been performed as minimally invasive surgery in recent years, it is more difficult to perform than open surgery. Our experience with endoscopic surgery using the latest surgical robot daVinci at our hospital has shown that robotic surgery is beneficial in terms of the safe and easy performance of difficult surgical techniques, however, one of its drawbacks use of the robot does not impart a feeling that the surgeon’s hands are touching the tissues, making meticulous procedures rather difficult (Anthony et al., 2004). In ordinary open surgery or endoscopic surgery, surgeons apply knot-tying force spontaneously based on their experience and the feel of the tissues being handled. In robotic surgery, on the other hand, the force exerted is decided on the basis of visual information alone, such as the tautness of the thread and degree of deformation of the tissue. We therefore thought that objective data should be obtained to determine the optimal knottying force to apply when suturing during robotic surgery. To achieve this goal we developed forceps for robotic surgery whose tips have six degrees of freedom ( Matsuhira et al., 2003) and a new system at our hospital that displays information about force at the tip of the forceps measured by a sensor to the surgeons on monitor or via auditory signals. No studies have ever been conducted to investigate the relationship between knot-tying force and the efficiency of wound healing in the operated tissue, or to estimate the optimal knot-tying force for tissues. We thought that knowing the optimal knot-tying force for tissues in terms of the efficiency of wound healing would make it possible to tie knots based on the information concerning the force at the tip of the forceps displayed during robotic surgery, and to provide basic data in vivo for the development of robotic forceps that impart a feeling that the surgeon’s hands are touching the sutures and tissues. The purpose of this study was to estimate the optimal knot-tying force by investigating the relationship between the force applied assessed on the basis of the information displayed on the surgeon’s monitor and the efficiency of wound healing in the gastrointestinal tract in canine models.
