PATIENT SPECIFIC ALIGNMENT GUIDE WITH CUTTING SURFACE AND LASER INDICATOR

摘要

A patient-specific guiding system for guiding an instrument relative to a portion of an anatomical feature of a patient. The patient-specific guiding system includes a patient-specific guide. The guide includes a first portion having a first patient-specific inner surface that conforms to a first surface of the anatomical feature and an outer surface opposite the first patient-specific inner surface. The first portion also includes a guide surface for use in guiding the instrument relative to the anatomical feature. The guide also includes a second portion having a second patient-specific inner surface that conforms to a second surface of the anatomical feature and an outer surface opposite the second patient-specific inner surface. The second portion is removably connected to the first portion.

1. A patient-specific guiding system for guiding an instrument relative to a portion of an anatomical feature of a patient, the patient-specific guiding system comprising:
a patient-specific guide having:
a first portion having a first patient-specific inner surface that conforms to a first surface of the anatomical feature and an outer surface opposite the first patient-specific inner surface, the first portion including a guide surface for use in guiding the instrument relative to the anatomical feature; anda second portion having a second patient-specific inner surface that conforms to a second surface of the anatomical feature and an outer surface opposite the second patient-specific inner surface, the second portion being removably connected to the first portion;wherein the first and second patient-specific inner surfaces each have a three dimensional contour that nests and closely conforms to the first and second surfaces, respectively, of the anatomical features, to align the guide relative to the anatomical feature.
