Abstract
A surgical positioning system including a rotation guide slide and a rotation guide pointer configured to be coupled to the rotation guide slide. The rotation guide pointer includes a base and a pointer extension. The base includes protrusion and a hole extending through the base and the protrusion where the protrusion is sized and configured to be received within a channel such that the rotation guide pointer can translate parallel to a plane defined by the first side of the rotation guide slide. The hole is sized and configured to receive a screw to fix the position of the rotation guide pointer relative to the rotation guide slide, with the protrusion configured to expand when the screw is advanced in the hole.
Claims15
A surgical positioning system, comprising:
- a first component including an elongate shaft coupled to a head, the head configured to be disposed in a joint between a first bone and a second bone;
- a second component having a first side and a second side, the second side opposite the first side, the second component defining a hole extending from the first side to the second side that is sized and configured to receive the elongate shaft of the first component, the second component further defining a first channel extending into the second component from the first side with a second hole extending from a third side to the hole, wherein the third side extends between the first side and the second side, and wherein the second hole is configured to receive a set screw for locking the position of the first component within the hole;
- and
- a third component configured to be coupled to the second component, the third component including a base and a pointer extension, the base including a protrusion that is sized and configured to be received slidably within the first channel such that the third component can translate parallel to a plane defined by the first side of the second component.
A positioning system, comprising:
- a slide having a first side spaced apart from a second side, the slide further defining a channel extending inwardly from the first side;
- a medial gutter fork including an elongate shaft coupled to a head, the head to be disposed between a tibia and a talus, wherein the slide defines a hole extending from the first side to the second side that is sized and configured to receive the elongate shaft of the medial gutter fork wherein the slide defines a second hole extending from a third side to the hole, with the third side extending between the first side and the second side, and wherein the second hole is configured to receive a set screw for locking the position of the medial gutter fork within the hole;
- and
- a pointer configured to be coupled to the slide, the pointer including a base and an extension, the base including a protrusion and defining a hole extending through the base and the protrusion such that the protrusion is slidably received within the channel such that the pointer translates parallel to the first side of the slide, and wherein the hole is sized to receive a screw to fix the position of the pointer relative to the slide, wherein the protrusion expands in response to the screw being advanced in the hole.
