Surgical Cutting Guide

摘要

The present invention is directed to a surgical cutting guide for guiding a surgical instrument along a cutting path located on a biological tissue. The surgical guide includes a contact surface that conforms to a surface associated with the tissue and at least one guide for restricting movement of a surgical instrument in a first direction and for allowing the movement of the surgical instrument in a second direction along a cutting path across the surface of the tissue. The guide further contains a stop for restricting movement of the surgical instrument in the second direction along the cutting path. The stop is based at least, in part, on patient specific information.

主权项

1. A method of making a surgical tool for repairing a knee joint of a patient, comprising:
obtaining electronic image data of the knee joint of the patient, obtaining, from the electronic image data, patient-specific information regarding a ligament of the knee joint of the patient, designing the surgical tool having a portion that substantially conforms to at least a surface portion of the knee joint of the patient, designing at least one guide configured to direct movement of a surgical instrument along a predetermined path, wherein the at least one guide is part of or linked to the surgical tool, and designing a stop based on the patient-specific information for preventing the surgical instrument from deviating from the predetermined path, wherein the stop is integrated into the at least one guide.
