“…Haptic simulators can help surgeons to learn minimally invasive procedures in a shorter period of time outside of the operating room (16). Although various haptic studies have been reported recently (17,18), no previous reports have utilized the approach used in the present study, which may be the first of its kind.…”

Currently available master-slave manipulators cannot recognize the elasticity of organs or tissues. The aim of this study was to examine whether a newly developed haptic forceps using a linear motor could measure the elasticity of living organs using an animal model. We measured the elasticity values and the disruption limit values of rat organs using the new haptic forceps. The elasticity of the materials was calculated using the formula "power / position", with N/m as the unit. We successfully and reproducibly measured the changes in the elasticity values of various materials in real time. We were also able to perceive tactile changes transmitted through the forceps. The changes in gastrointestinal contraction were synchronized with the visually observed changes, and these changes were monitored and measured as elasticity values in real time using the forceps. The damage limits were also successfully measured. In conclusion, the new haptic forceps enabled highly sensitive, real-time measurements of elasticity in living rat organs. The use of this forceps enables the disruption limit values of organs to be measured, and the device could be useful for setting safety limits when grasping organs during endoscopic surgery.

We have developed a computer based simulation process which allows a surgical expert to create a customized operative environment. This virtual environment, the Toolkit for Illustration of Procedures in Surgery (3D TIPS), is deployed on a low-cost computer system and requires minimal training for the programmer. The learner can be engaged in training immediately and the educator can modify the system and annotate the procedure to highlight specific points using video clips, operative images, and the like. A laparoscopic adrenalectomy is presented as a proof of concept in the accompanying article.

“…This feedback is derived using a manipulator to apply a degree of opposing force to the user along the x-, y-and z-axes. Haptic interfaces can be used to simulate operations and actions like deformation and cutting, and three-dimensional (3D) haptic devices can be employed in applications such as the simulation of complex surgical procedures and the training of unskilled surgeons [8,9]. Moreover, when employing a haptic approach, designers can model freehand, using the interface as a virtual cutting tool and carving away simulated clay on screen, exploiting both visual and tactile feedback.…”
