Abstract
Various embodiments of devices, systems, and methods for surgical procedures, including spring-fit guides for improved guidance of surgical instruments, are disclosed.
Claims13
A system for treatment of a joint of a patient, the system comprising:
- a first guide for a surgical instrument;
- and
- an implant component to be implanted in the joint,
- wherein the first guide comprises:
- a body having a guide slot extending through at least a portion of the body from a first side of the body to a second side of the body,
- wherein the guide slot is configured to receive the surgical instrument through an entrance opening and guide the surgical instrument along a path extending from an exit opening in a direction substantially opposite the entrance opening and substantially along a predetermined cutting plane,
- wherein the entrance opening is located on the first side of the body and the exit opening is located on the second side of the body,
- wherein a cutting-plane side wall of the guide slot includes at least a portion substantially located within the cutting plane,
- wherein an opposing side wall of the guide slot is positioned substantially opposite the cutting-plane side wall and includes at least one spring-fit structure, the at least one spring-fit structure comprising:
- a guide surface substantially facing the cutting-plane side wall;
- and
- a flexing portion connected to the body and supporting at least a portion of the guide surface, the flexing portion configured to allow at least a portion of the guide surface to move in a direction away from the cutting plane when the surgical instrument is inserted into the guide slot and contacts at least a portion of the guide surface, and
- wherein the body further comprises at least one alignment surface having at least a portion with a shape based, at least in part, on patient-specific information regarding a surface of the patient's joint such that the guide can be positioned against and aligned with the corresponding surface of the patient's joint in a predetermined position and/or orientation, the alignment surface making up at least a portion of the second side of the body.

A guide for a surgical instrument for use in treating a joint of a patient, the guide comprising:
- a body having a guide slot extending through at least a portion of the body from a first side of the body to a second side of the body,
- wherein the guide slot is dimensioned to receive the surgical instrument through an entrance opening and guide the surgical instrument along a path extending from an exit opening in a direction substantially opposite the entrance opening and substantially along a predetermined cutting plane,
- wherein the entrance opening is located on the first side of the body and the exit opening is located on the second side of the body,
- wherein a cutting-plane side wall of the guide slot includes at least a portion substantially located within the cutting plane,
- wherein an opposing side wall of the guide slot is positioned substantially opposite the cutting-plane side wall and includes at least one spring-fit structure, the at least one spring-fit structure comprising:
- a guide surface substantially facing the cutting-plane side wall;
- and
- a flexing portion connected to the body and supporting at least a portion of the guide surface, the flexing portion configured to allow at least a portion of the guide surface to move in a direction substantially away from the cutting plane when the surgical instrument is inserted into the guide slot and contacts at least a portion of the guide surface, and
- wherein the body further comprises at least one alignment surface having at least a portion with a shape based, at least in part, on patient-specific information regarding a surface of the patient's joint such that the guide can be positioned against and aligned with the corresponding surface of the patient's joint in a predetermined position and/or orientation, the alignment surface making up at least a portion of the second side of the body.
