A USER INTERFACE FOR A SURGICAL SIMULATION SYSTEM

摘要

A user interface device (1) comprising a frame (11) with a support (15) and a suspension portion (16) rotatable around a first axis (A). Further comprising a camera simulator (10) having a rigid shaft (21) with a primary extension along a longitudinal axis (C), being suspended by the suspension portion (16) so that it can translate along the longitudinal axis (C). A first rotational sensor (25) arranged to detect rotation of the suspension portion (16) around the first axis (A) by a guiding surface (18a) arranged at a distance from the first axis (A), and a first roller (30) arranged between the axis (A) and the guiding surface (18a) to rotate when the suspension portion (16) is rotated around the first axis (A) wherein the first rotational sensor (25) is arranged to detect rotation of the first roller (30). This solution enables satisfactory measured resolution at more reasonable price.

1. A user interface device for a surgical simulation system, said interface comprising:
a frame having a support and a suspension portion rotatable around a first axis in relation to said support; an instrument having a rigid shaft with a primary extension along a longitudinal axis non-parallel to said first axis; said shaft being suspended by said suspension portion so as to be translatable along said longitudinal axis in relation to said suspension portion; a first rotational sensor arranged to detect rotation of said suspension portion around said first axis with respect to said support; a guiding surface arranged at a distance from said first axis, and fixed in relation to said support; and a first roller arranged between said first axis and said guiding surface, said first roller being frictionally engaged with said guiding surface, so as to rotate when said suspension portion is rotated around said first axis with respect to said support; wherein said first rotational sensor is arranged to detect rotation of said first roller.
