Abstract
A universal tracking array apparatus that can be attached to various tools, e.g., surgical instruments, to enable the tools to be tracked, e.g., with a surgical navigation system. The apparatus includes first and second clamp bodies with a ratcheting mechanism to couple the bodies together and form a clamp to retain the instrument. The first clamp body also supports a tracking array, and can support the tracking array in a plurality of selectable positions.
Claims12
An apparatus, comprising:
- a tracking array having a plurality of fiducial markers;
- a first clamp body having:
- a mounting surface configured to support the tracking array, the mounting surface including a plurality of radial guide grooves arranged about an axis of the first clamp body, the radial guide grooves configured to define a set of predetermined discrete angular orientations of the tracking array relative to the first clamp body;
- a first fastener comprising a pair of slots extending within a side wall of the first clamp body from an end of the first clamp body to respective exits on sides of the first clamp body, and a pair of deformable tabs adjacent the respective exits, each deformable tab including one or more teeth;
- and
- a first clamping surface;
- and
- a second clamp body having:
- a second fastener complementary with the first fastener, the second fastener comprising a pair of tongues configured to be inserted into the pair of slots, each tongue having a serrated outer surface configured to engage with the teeth of the deformable tabs to permit insertion of the tongues into the slots and to resist withdrawal of the tongues from the slots absent outward deformation of the deformable tabs;
- and
- a second clamping surface configured, when the second clamp body is coupled with the first clamp body, to define a clamping jaw for retaining an instrument;
- and
- wherein the tracking array includes a protrusion configured to selectively engage a selected one of the radial guide grooves to maintain the tracking array at a selected one of the predetermined discrete angular orientations.
