Abstract
A mount for holding a reference frame during a surgical procedure. The mount includes a reference frame connector at a first end of the mount. A shank connector is at a second end of the mount. The shank connector is configured to receive a head of a shank within the shank connector. The shank connector includes a set screw movable to contact the head to lock the shank connector to the head of the shank. A support rod extends between the reference frame connector and the shank connector.
Claims16
A mount for holding a reference frame during a surgical procedure, the mount comprising:
- a reference frame connector at a first end of the mount;
- a shank connector at a second end of the mount, the shank connector is configured to receive a head of a shank within the shank connector, the shank further comprising a tip configured to be secured to a bone, the shank connector including a set screw configured to be screwed into a main body of the shank connector and movable to contact the head to lock the shank connector to the head of the shank, wherein the main body of the shank connector comprises a proximal end and a distal end, at the distal end the main body defines a distal opening, the set screw extends through the proximal end into the main body, wherein the main body further defines a side window adjacent to the distal end, at the side window is a recess that is adjacent to a flange at the distal end, and further wherein the side window is configured to receive the head of the shank by sliding the main body over the head in a direction perpendicular to a longitudinal axis extending through the main body;
- and
- a support rod extending between the reference frame connector and the shank connector.
A mount for holding a reference frame during a surgical procedure, the mount comprising:
- a reference frame connector at a first end of the mount;
- a shank connector at a second end of the mount, the shank connector including a main body defining a receptacle, a distal opening, and a side window adjacent to the distal opening configured to receive a head of a shank, wherein the side window is configured to receive the head of the shank by sliding the main body over the head in a direction perpendicular to a longitudinal axis extending through the main body, and further wherein the shank further comprises a tip configured to be secured to a bone;
- and
- a support rod extending between the reference frame connector and the shank connector.
A method for performing a navigated surgical procedure comprising;
- securing a shank to a bone;
- connecting a mount holding a reference frame to the shank by sliding a shank connector of the mount onto a head of the shank so that the head passes through a side window defined by a main body of the shank connector into a receptacle defined by the main body;
- tightening a set screw of the shank connector so that the set screw contacts the head of the shank to apply pressure to the head and secure the head within the receptacle;
- using the reference frame during the navigated surgical procedure;
- detaching the mount from the shank after use of the reference frame has concluded;
- and
- attaching a bracket to the shank after the mount has been detached from the shank, the bracket configured to couple with an implant.
