User interface device for surgical simulation system
First Claim
1. A user interface device for a surgical simulation system, comprising:
- a rigid shaft having a primary extension along a longitudinal axis, said rigid shaft being pivotably supported by a frame, and movable in relation to said frame in an axial direction, said rigid shaft being fixed in relation to said frame with respect to rotation around said longitudinal axis; and
a handle having a sensor body rigidly attached to said rigid shaft, and a grip portion rotatable around said longitudinal axis relative said sensor body, said grip portion being adapted to transform a gripping motion of a user into a linear displacement,said handle further comprises;
a rotator sleeve rotatable around said longitudinal axis relative said sensor body and said grip portion,a rotation sensor adapted to detect rotation of said rotator sleeve in relation to said sensor body, anda signal interface mounted on said sensor body and connected to receive a first detection signal from said rotation sensor.

Abstract
A user interface device for a surgical simulation system, comprising a rigid shaft pivotably supported by a frame, and movable in the axial direction but fixed with respect to rotation around its longitudinal axis, and a handle having a sensor body rigidly attached to said rigid shaft, and a grip portion rotatable around said longitudinal axis relative said sensor body. The handle further comprises a rotator sleeve rotatable around said longitudinal axis relative said sensor body and said grip portion, a rotation sensor adapted to detect rotation of said rotator sleeve in relation to said sensor body, and a signal interface mounted on said sensor body and connected to receive a first detection signal from said rotation sensor. Through this design, all sensor elements and electronic circuitry can be provided in or adjacent to the sensor body, leading to an efficient design and manufacturing.
