This invention relates to the smart Telesurgical robotic endotrainer used for robotic surgery training. This surgical robot provides a real-time surgical experience using an endotrainer wherein the operations are controlled by the surgeon through completely programmed controllers. This is used for achieving better training for surgeons prior to robotic surgery in patients. This will provide the best results for Urology surgeries (Cancer, Transplantations, etc), Cardiology (Heart Surgeries), General Surgeries etc.

The currently available DaVinci surgical robot is very expensive and is complex to operate. To overcome these disadvantages STeROBOT is proposed and developed. STeROBOT provides a simple and economical Telesurgical endotrainer for use in robot surgery training by surgeons. It provides both 3D and 2D view and is easy to operate. It provides real hands-on robotic surgery training.

Also 4 novel arms (Telesurgical Scissor, Telesurgical Needle Holder, Telesurgical Grasper, and Telesurgical Hook) to fit and operate with STeROBOT is developed. Each arm is designed, assembled and developed with 108 small precise components. These arms perform various tasks inside human body or inside endotrainer in accordance to the operations performed by surgeons during surgery. The arms provide all seven degrees of freedom.

The advantages of STeROBOT are

1) Minimally invasive
2) High precision
3) Easy to learn and operate
4) Low investment and maintenance costs.
5) Reduces hospital stay for patients
6) Provides real surgery experience
7) Can be used in Urology, Cardiology and general surgeries
8) Provides both 3D and 2D view
9) Can be operated from remote location
10) Less strain for surgeons
11) Reduces operating time for surgeons
