Adjustable guide in computer assisted orthopaedic surgery

The present invention relates to a device for adjusting the position of a surgical instrument () with respect to a solid () tracked by a navigation system (), wherein the instrument () comprises a fixed part () that is rigidly fixed to the solid () and a mobile part () that is attached to the fixed part by screws (), the device () comprising:

Device and method for instrument adjustment in computer assisted surgery

The invention concerns a device for adjusting the position of a screw () that is able to move a part of a surgical instrument, said device () comprising: &#x2014;a stem () comprising a tip () suited to the head () of the screw (), &#x2014;an actuated system () for driving said stem () in rotation, &#x2014;communication means to communicate with a control unit (), such that the control unit () transmits to the actuated system () the number of turns to apply to the stem () to reach the target position of the screw (). The invention also concerns a surgical system for alignment of surgical guide means (), comprising: &#x2014;a positioning unit comprising a fixed part () and a mobile part () supporting the surgical guide means (), the position of said mobile part () being adjustable with respect to the fixed part () by screws (), &#x2014;a referencing unit for detecting the position of the positioning unit with respect to a target position of the surgical guide means, &#x2014;a control unit () for computing the target position of screws (), &#x2014;said device () for adjusting the positions of the screws ().

Device for controlled adjustment of a surgical positioning unit

In an embodiment, the methodology of the present invention is based on the use of an intraoperative navigation system and of a compact alignment guide for alignment of implant components. In an embodiment, an alignment guide of the present invention includes a first component fixable to a bone element; a second mobile component, and a third mobile component, wherein the second mobile component and two control mechanisms form a first link, wherein the two control mechanisms are working in parallel to perform adjustments in two degrees of freedom, wherein the third mobile component and three control mechanisms form a second link, wherein the three control mechanisms are working in parallel to perform adjustments in three additional degrees of freedom, and wherein the first link adjustments and the second link adjustments are performed in series to provide a total adjustment of five degrees of freedom relative to the first component.
