Operating device for laparoscopic surgery training instrument, comprises body movable over flat surface and used to supply movement signals to instrument

摘要

The operating device (1) comprises a body (2) which can be moved over the surface of a flat panel or tabletop (3) and is provided with a displacement sensor for converting a displacement of the body over this surface into electric signals, which are supplied to the instrument via a connecting cable (8). The body includes a mechanism for restricting the degree of freedom of movement to a translation and rotary movement relative to a fixed point defined by this mechanism. An Independent claim is also included for a computer with simulation software used for laparoscopic surgery training, which has the above device connected to it and in which the simulation software converts the electric signals from the displacement sensor into polar coordinates from Cartesian coordinates.
