Location device for locating position of to-be treated part of patient during computer assisted surgery, has holding unit whose size along direction perpendicular to vertical plane is less than size along another direction

摘要

The device (1) has sensors (2a, 2b) for detecting the position of an object in a space and arranged on a holding unit (4) carried by a support unit (5) to ensure maintenance of the sensors according to first direction (I). The sensors are directed according to a common detection direction (II-II). Size (E1) of the holding unit along second direction (III-III) perpendicular to a vertical plane (P) defined by the directions is less than size (E2) along the first direction. The support unit is designed to manage the first direction to be contained in the plane.
