用于外科定位单元的受控调整的装置

Device for controlled adjustment of a surgical positioning unit
Abstract:
The invention concerns a device for adjusting the position of a screw (13) that is able to move a part of a surgical instrument, said device (4) comprising: —a stem (41) comprising a tip (42) suited to the head (130) of the screw (13), —an actuated system (45) for driving said stem (41) in rotation, —communication means to communicate with a control unit (21), such that the control unit (21) transmits to the actuated system (45) the number of turns to apply to the stem (41) to reach the target position of the screw (13). The invention also concerns a surgical system for alignment of surgical guide means (14, 15), comprising: —a positioning unit comprising a fixed part (11) and a mobile part (12) supporting the surgical guide means (14, 15), the position of said mobile part (12) being adjustable with respect to the fixed part (11) by screws (13), —a referencing unit for detecting the position of the positioning unit with respect to a target position of the surgical guide means, —a control unit (21) for computing the target position of screws (13), —said device (4) for adjusting the positions of the screws (13).
