Abstract
Trajectory frame assemblies for image guided surgical systems have a trajectory frame with a support column that can removably secure different components such as a tracking probe and an MER driver adapter to define and/or follow a desired intrabody trajectory. The trajectory frame assemblies include fins attached to the column support and a platform optionally with an X-Y table and/or arcuate reference brackets that are attached to the trajectory frame assemblies and can hold a reference frame with fiducials.
Claims20
A trajectory frame assembly for use with a surgical system, comprising:
- a base having a patient access aperture formed therein, wherein the base is configured to be secured to a body of a patient;
- a yoke movably mounted to the base and rotatable about a roll axis;
- a platform movably mounted to the yoke and rotatable about a pitch axis, wherein the platform comprises an X-Y support table movably mounted to the platform that is configured to move in an X-direction and Y-direction relative to the platform;
- a support column secured to the X-Y support table of the platform;
- and
- a plurality of circumferentially spaced apart fins extending radially outward from the support column to the X-Y support table.

- a platform movably mounted to the yoke and rotatable about a pitch axis, wherein the platform comprises an X-Y support table movably mounted to the platform that is configured to move in an X-direction and Y-direction relative to the platform;
- a support column secured to the X-Y support table of the platform;
- a plurality of circumferentially spaced apart fins extending radially outward from the support column to the X-Y support table;
- a reference bracket attached to a laterally extending segment of the base under the yoke, wherein the reference bracket has an arcuate bridging arm extending between a first connector and a second connector, at least one of which comprising a starburst connector configuration with a serrated segment and a bore, wherein the reference bracket is configured to attach to a reference frame with a plurality of spaced apart arms comprising fiducials and/or tracking members,
- wherein the arcuate bridging arm has a perimeter with opposing laterally spaced apart long sides, one at a first radius of curvature and one at a greater second radius of curvature, the first radius of curvature that is between 0.5 inches and 2 inches.

- a support column secured to the X-Y support table of the platform;
- a plurality of circumferentially spaced apart fins extending radially outward from the support column to the X-Y support table;
- and
- a reference bracket attached to a laterally extending segment of the base under the yoke, wherein the reference bracket has a bridging arm extends between a first connector on one end portion and second and third connectors on an opposing second end portion, wherein the second and third connectors comprise a starburst connector configuration with at least one outer surface comprising a serrated segment and a bore, and wherein an axially extending centerline of the bore of the second connector intersects that of the third connector.
