Patent ID: 11896319
Assignee: CAIRA SURGICAL
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 0:
1. A system for tracking a medical object, the system comprising:
a first radio frequency transceiver that emits a first radio frequency signal at a first frequency;
a second radio frequency transceiver that emits a second radio frequency signal at a second frequency;
a third radio frequency transceiver that emits a third radio frequency signal at a third frequency;
a radio frequency beacon comprising:
a platform;
a first fixation element extending orthogonally from the platform; and
a second fixation element extending at an oblique angle from the platform;

wherein the radio frequency beacon performs operations comprising:
emitting a fourth radio frequency signal at a fourth frequency in response to receiving the first radio frequency signal;
emitting a fifth radio frequency signal at a fifth frequency in response to receiving the second radio frequency signal; and
emitting a sixth radio frequency signal at a sixth frequency in response to receiving the third radio frequency signal; and

a control device in communication with the first radio frequency transceiver, the second radio frequency transceiver, and third radio frequency transceiver, the control device including processing circuitry that determines a location of the medical object in three-dimensional space based at least in part on the fourth radio frequency signal, the fifth radio frequency signal, and the sixth radio frequency signal.
