Abstract
Various systems, devices, and methods for facilitating efficient anatomical registration in surgical navigation are disclosed. Such systems and devices can have a data collection unit and a scaling device. The scaling device has a main body having an anatomical registration feature defined therein and at least one scaling marker pathway that is selectively oriented with respect to the anatomical registration feature to facilitate repeatable gross placement of a scaling marker relative to a selected anatomical feature. The scaling marker is selectively displaceable along a scaling marker pathway about and between a first end and a second end thereof to fine-tune scaling marker placement prior to image capture.
Claims20
A scaling device, comprising:
- a main body having at least one anatomical registering feature defined therein, wherein the main body is conformable to a selected anatomical structure, wherein the main body further comprises a scaling marker pathway that is selectively oriented with respect to the anatomical registering feature at a fixed distance and facilitates repeatable gross placement of a scaling marker relative to the selected anatomical structure, wherein the scaling marker pathway has a first end and an opposed second end, and wherein the scaling marker is selectively displaceable along the scaling marker pathway about and between the first end and the second end to enable fine placement of the scaling marker relative to the selected anatomical structure along a fixed path less than an overall length of the main body.
A scaling device, comprising:
- a scaling marker;
- a main body extending from a first end to a second end and being stretchable to surround and conform to an anatomical structure of a knee, the main body comprising:
- an anatomical registering feature comprising a hole extending through the main body for receiving a patella;
- and
- a scaling marker pathway disposed in the main body at a fixed distance from the anatomical registration feature, the scaling marker pathway extending from a third end to a fourth end to extend across a medial or lateral side of the anatomical structure of the knee;
- and
- a closure mechanism for attaching the first and second ends of the main body at a posterior side of the anatomical structure of the knee;
- wherein the scaling marker is selectively displaceable along the scaling marker pathway between the first end and the second end.
