The University of Florida is actively seeking companies interested in commercializing an unparalleled 3-dimensional simulation environment that easily interfaces with novel surgical instruments. The rapid development and deployment of novel, minimally invasive instruments present the surgical educator with a significant challenge. Several useful laparoscopic instruments have been particularly difficult to teach the novice. Maximizing trainee proficiency in a limited amount of time, while ensuring patient safety, has also proven to be very challenging. Researchers at the University of Florida have developed a platform that allows the combination of the actual instrument handle with a virtual re-creation of the instrument tip. The developed virtual environment allows re-creation of the necessary motion to simulate the instrument, the trainee can use the actual instrument handle, and the system can be altered to accommodate other instruments.


Utilized to teach the operation of instruments, specifically laparoscopic instruments


  • User can repeatedly perform maneuvers that accurately simulate the actual instrument in the virtual world providing unparalleled learning tool
  • The apparatus has haptic capabilities and collision detection so that instrument to instrument contact is experienced maximizing the learning experience and providing major competitive advantage over existing training tools
  • The system can be altered to accommodate other surgical instruments which provides an unequaled testing environment and multiple product opportunities
  • True virtual reality reconstruction of suture has been accomplished and is deployable in this medium, providing unique learning opportunity


The laparoscopic suturing instrument consists of a handle and a distal head piece that is controlled at the handle by a surgeon. The handle is interfaced to an Omni Phantom haptic interface device that allows a user to perform suturing exercises in a virtual environment. Subsequent software interpretation of the given interface allows for complete emulation of the suturing procedure in virtual space. In the developed model the instrument handles can be attached to a virtual reality computer system where the working “tip” of the instrument is displayed on a computer screen and the user holds the actual handle of the instrument.
