Development of optical based micro electro mechanical systems (MEMS) tactile sensor for vinci robotic surgical system

In the recent decades, Microelectro Mechanical Systems (MEMS) is playing a well-known function in the improvement of several new and original biomedical devices. In this work MEMS is used for Surgery applications with lower risk, and help control costs by providing the surgeon with real-time feedback on the operation. Presently, Minimally Invasive Surgery (MIS) performs all the way through keyhole incisions by commercially presented robotic surgery systems. The make use of of robot assistance has helped in the direction of recognize the full possible of MIS with increased consistency, protection and accurateness. The improvement of expressed, correctness tools in the direction of increase the surgeon’s dexterity has developed in parallel with advances in imaging and human-robot interaction. In these work robotic surgery systems is worked based on the famous da Vinci surgical system. These system surgeons are faced with problems such as lack of tactile feedback at the time of surgery. This surgery system is applied to real-time tactile feedback between surgical instruments and tissue is able to assist the surgeons to execute MIS more consistently. It also uses an optical tactile sensor to evaluate the make contact with strength among the bio-tissue and the surgical tool. A model is introduced designed for simulating the interaction among a flexible crust and bio-tissue depending on the finite element process. The tissue is measured as a hyper elastic material by means of the fabric characteristics comparable to the heart tissue. The simulations results are used to optimize the geometric characteristics of a proposed MEMS tangible sensor for use in robotic surgical system in the direction of perform MIS.
