Abstract: A haptic device for a gastrointestinal endoscope simulator is provided to offer the sense of touch and haptic interface to a user and to transmit a value output by measuring the operation of a user for a device unit, to a haptic control unit. A haptic device for a gastrointestinal endoscope simulator comprises a support, a rectilinearly moving unit(210), and a roll turning unit(220). The rectilinearly moving unit is installed at the support to move rectilinearly. The rectilinearly moving unit provides information about a rectilinear motion of an endoscope tube generated by the operation of a user, to a control unit of the gastrointestinal endoscope simulator and transmits rectilinear force to the user through a control handle. The roll turning unit is rotatably fixed at the rectilinearly moving unit to turn the endoscope tube. The roll turning unit provides information about a roll rotary motion of the endoscope tube generated by the operation of the user, to the control unit of the gastrointestinal endoscope simulator and transmits rotational torque to the user through the control handle. The rectilinearly moving unit comprises a pair of guide rods of which both ends are fixed to the support, respectively; a first plate installed at a pair of guide rods to move rectilinearly and fix one side of the endoscope tube; a second plate moving rectilinearly by interlocking with the first plate and supporting the endoscope tube to move the endoscope tube freely while passing the front end of the endoscope tube; and a wire driving type motor installed at one side of the second plate to fix both ends of a wire wound around a shaft, to the support.

Abstract: A large intestine model generating method, a collision checking method, and an endoscope simulation method using the same are provided to offer complete endoscope simulation by effectively checking collision between a virtual endoscope and a large intestine model in real time and feeding back the checked result, thereby providing environment in which unskilled doctors can learn various complicated medical treatments safely and effectively. A large intestine model generating method comprises the following steps of: analyzing plural CT(Computerized Tomography) data to extract a large intestine(S21,S22); making the 3D(Three-Dimensional) image of the extracted large intestine and extracting the center line of the 3D large intestine model(S23,S24); and restoring the surface of the 3D large intestine model based on the center line(S26).
