Surgical Technology

   

Surgical Technology is the application of advanced technology to minimally invasive surgery (MIS) training and procedures. The research is focused on following trusts: surgical robotics, objective assessment of surgical performance, simulation, and the biomechanics of soft tissue that are related MIS procedures.

The research is conducted as part of a long term collaboration between the Biorobtics Lab and the Center of Video Endoscopic Surgery (CVES) at the University of Washington co-chaired by Mika Sinanan MD., Ph.D.


    Devices

Surgical Robot System for Open and Minimally Invasive Surgery - The surgical robotic system includes two portable surgical robotic arms (7 Degrees of Freedom each) and is capable of teleported from a distance via Internet (wired & wireless). The system can be deployed in a hospital operating room setup as well as an operating room in harsh environment (e.g. desert).
| Status: Active Use |


RedDRAGON - The RedDRAGTON is a system for measuring the kinematics and the dynamics of two endoscopic tools along with the visual view of the surgical scene during the course of a surgical procedure. The system can be used in three different modalities: animal model, physical model simulator, virtual reality simulator.
| Status: Active Use |


Motorized Endoscopic Grasper (MEG) - The MEG is a 1 degree-of-freedom device incorporates force and position sensors and actuated by a DC motor for measuring Biomechanical characteristics of soft tissues in-vivo and in- vitro
| Status: Active use |


BlueDRAGON - The BlueDRAGTON is a system for measuring the kinematics and the dynamics of two endoscopic tools along with the visual view of the surgical scene during the course of a surgical procedure.
| Status: Non Active |


Force Reflective Endoscopic Grasper (FREG) - The FREG is a 1 degree-of-freedom device incorporates force feedback teleoperation technology into an existing, reusable, endoscopic grasper for minimally invasive surgery.
| Status: Non Active |

     

Instrumented Endoscopic Tool (IET) - The instrumented endoscopic surgical grasper incorporates sensors for measuring forces torques and applied by a surgeon on the tool during the course of a surgical procedure
| Status: Non Active (part of the Red Dragon)|

   

Hidden Markov Model Toolbox for MATLAB - The Hidden Markov Model (HMM) Toolbox for Matlab is a library of functions (M-files) that were written in Matlab's script language implementing both the discrete version (DHMM) and the continuous version (CHMM) of the HMM.
| Status: Beta Testing |
