COMPUTER-ASSISTED SURGERY TOOLS AND SYSTEM

摘要

A surface digitizing tool (150) has a film (152) of micro-sensor elements (152', 154), with each micro-sensor element (152', 154) related in a networ k affected by a shape of the film (152). The film (152) is flexible to confo rm to a shape of a selected surface of an object. A processing unit (201) re ceives signals from the micro-sensor elements (152', 154) of the network. Th e processing unit (201) has a model generator (216) producing a model of the selected surface of the object from the signals of the network of resistive elements. A positioning frame (170) aligns a position and orientation of a drilling tool with respect to a bone element.
