A laparoscopic cholecystectomy is a complex surgical procedure that requires good hand-eye coordination and dexterous skill on the part of the surgeon. The intent of this project is to develop a software module to digitally record the motions of the surgeon while performing the surgery.
2. Hardware.
The virtual glove hardware used is the commercially available 5DT DataGlove system (see Figure 1). The 5DT DataGlove system provides an economic hardware platform to develop the motion tracking software modules. The development computer is a Windows NT workstation with dual Pentium processors and the Wildcat OpenGL graphics accelerator. The graphics modules make calls to EAI/Sense8's WorldToolkit API of OpenGL calls.

3. Modeling and Software.
The three dimensional (3D) models of the virtual hand with separate finger objects, the virtual laparoscopic tool, galbladder and ducts were built in 3D Studio Max and are stored as 3ds files. These models are loaded into the graphics simulation. The software module records the motions of the user. This is accomplished by recording the positions and orientations of all 3D graphics objects. Thus, the 3D graphics are used to replay the technique, showing the user what he/she did during the surgery session.
