REGISTRATION POINTER WITH INTERCHANGEABLE TIP AND METHOD |
摘要 |
A registration pointer (10) for registering points of surfaces of bodily elements in computer-assisted surgery, comprising a handle (20) for being manipulated by a pointer operator. A stem (40) is connected to the handle (20) and has a first and a second tip configurations (47, 51) each having a respective use relating to a registration of points on specified bodily elements. A detectable device (30) is secured to the stem, and is adapted to be tracked in space for position and orientation by a sensing apparatus (102). A position of the tip configurations (47, 51) with respect to the detectable device (30) is determinable such that a position of the tip configurations (47, 51) is calculable as a function of the position and orientation of the detectable device (30). The tip configurations (47, 51) are chosen to register points on given bodily elements as a function of the respective use, by recording a position of points of contact between the tip configurations (47, 51) and the given bodily element. |
