Abstract
Various embodiments of an emitter-aligned surgical guide and methods of use are disclosed. The emitter-aligned surgical guide includes a body extending between a first surface and a second surface. The body defines at least one hole extending from the first surface to the second surface. At least one alignment jig is coupled to the second surface. The at least one alignment jig includes a jig arm extending from a first end coupled to the second surface of the body to a second end and an emitter support configured to couple an emitter device to the at least one alignment jig in a predetermined position relative to the body.
Claims15
An emitter-aligned surgical guide, comprising:
- a body extending between a first surface and a second surface, the body defining at least one hole extending from the first surface to the second surface and configured to:
- receive a fixation element, and
- properly align with a target site;
- a first alignment jig and a second alignment jig coupled to the second surface, comprising:
- a jig arm extending from a first end coupled to the second surface of the body to a second end wherein the first alignment jig fixedly positions a first emitter device to project a first emitted mark in a first plane and is configured to position the first emitter device at a first predetermined location and a first predetermined angle with respect to the body and the second alignment jig fixedly positions a second emitter device to project a second emitted mark in a second, non-parallel plane, the first and second emitted marks being configured to reference distinct anatomical landmarks spaced apart from the guide body;
- and
- an emitter support configured to fixedly couple at least one of the first and second emitter device to the at least one alignment jig in a predetermined position and angle relative to the body, wherein the first surface comprises a patient-specific topography configured to mate with a complementary anatomical surface of a patient thereby properly aligning the at least one hole with the target site, and further wherein the emitter support is positioned such that, when the patient-specific topography is securely seated on the patient's anatomy, the at least one of the first and second emitter device projects an emitted mark that references a predetermined second anatomical location spaced apart from the first surface.

A system, comprising:
- an emitter-aligned surgical guide, comprising:
- a body extending between a first surface and a second surface, the body defining at least one hole extending from the first surface to the second surface and configured to properly align with a target site;
- a first alignment jig and a second alignment jig coupled to the second surface, the first alignment jig comprising:
- a jig arm extending from a first end coupled to the second surface of the body to a second end wherein the first alignment jig is configured to position a first emitter device at a first predetermined location and a first predetermined angle with respect to the body and a second alignment jig is configured to position a second emitter device at a second predetermined location and a second predetermined angle with respect to the body;
- and
- an emitter support configured to fixedly couple at least one of the first and second emitter device to the at least one alignment jig in a predetermined position and angle relative to the body, wherein the first surface comprises a patient-specific topography configured to mate with a complementary anatomical surface of a patient thereby properly aligning the at least one hole with the target site, and further wherein the emitter support is positioned such that, when the patient-specific topography is properly seated on the patient's anatomy, the at least one of the first and second emitter device projects an emitted mark that references a predetermined second anatomical location spaced apart from the first surface;
- and
- at least one guide element sized and configured to be received within the at least one hole defined by the body of the emitter-aligned surgical guide;
- and
- at least one additional surgical guide configured to be coupled to one of the emitter-aligned surgical guide or the at least one guide element.
7 more elements
A method, comprising:
- positioning an emitter-aligned surgical device adjacent to a first anatomical location, wherein the emitter aligned surgical device comprises:
- a body extending between a first surface and a second surface, the body defining at least one hole extending from the first surface to the second surface;
- an alignment jig coupled to the second surface, the alignment jig comprising:
- a jig arm extending from a first end coupled to the second surface of the body to a second end including a first alignment jig and a second alignment jig wherein the first alignment jig is configured to position a first emitter device at a first predetermined location and a first predetermined angle with respect to the body and a second alignment jig is configured to position a second emitter device at a second predetermined location and a second predetermined angle with respect to the body;
- and
- an emitter support fixedly coupled to at least one of the first and second emitter device, wherein the alignment jig positions the at least one of the first and second emitter device in a predetermined position and angle relative to the body, wherein the first surface comprises a patient-specific topography configured to mate with a complementary anatomical surface of a patient thereby properly aligning the at least one hole with the target site, and further wherein the emitter support is positioned such that, when the patient-specific topography is properly seated on the patient's anatomy, the at least one of the first and second emitter device projects an emitted mark that references a predetermined second anatomical location spaced apart from the first surface;
- generating an emitted mark from the at least one of the first and second emitter device;
- and
- positioning the emitter-aligned surgical device at the first anatomical location such that the emitted mark from the at least one of the first and second emitter device is aligned at a predetermined second anatomical location.
