Zusammenfassung:A customized surgical fixture ( 400 ) is formed by scanning a body to form a three-dimensional image of the body, and then identifying in the image a target ( 310 ) in the body, and mounting points or structures ( 330 ) on the body. A model, such as a computer solid model, of the fixture ( 400 ) is specified in accordance with the locations of the target ( 310 ) and mounting structures ( 330 ) or points. The fixture ( 400 ) is formed in accordance with the model of the fixture ( 400 ), for example using a rapid prototyping and tooling machine. When attached to the body, the fixture ( 400 ) can be used to guide a surgical instrument ( 610 ) into the body, for example, by using a mechanical guide ( 600 ) attached to the fixture ( 400 ) or using a remote sensing device ( 1300 ) that tracks the relative position of the customized fixture ( 400 ) and the surgical instrument.
