US 10,265,854 B2 · Operating room safety zone

Abstract

Methods and devices for identifying and defining a safety zone for restricting movement of a robotic arm in an operating room during a medical procedure are disclosed. The disclosed method utilizes medical navigation system, which receives an initiation input indicating initiation of defining of the safety zone. In response to receiving the initiation input, the system tracks an instrument and determines the location of the tracked instrument relative to a reference point. The system detects changes in the location of the tracked instrument until a termination input is received at the medical navigation system. The termination input indicates the termination of the defining of the safety zone. The system stores, in memory, change data indicative of the changes in the location of the tracked instrument. The data identifies the safety zone relative to the reference point.

Dependent claims

A method for identifying a safety zone, using a medical navigation system, for restricting movement of a robotic arm in an operating room, the method comprising:

receiving, at the medical navigation system, an initiation input indicating initiation of defining of the safety zone;
in response to receiving the initiation input,
tracking an instrument using the medical navigation system,
determining a location of the tracked instrument relative to a reference point, and
detecting changes in the location of the tracked instrument until a termination input is received at the medical navigation system, the termination input indicating termination of the defining of the safety zone;
and
storing, in memory, change data indicative of the changes in the location of the tracked instrument, the data identifying a spatial position of the safety zone relative to the reference point,
wherein the safety zone is definable by at least one gesture instrument, and
wherein the safety zone is spatially shiftable if the reference point shifts.

6 more elements

A medical navigation system comprising:

a tracking system;
a processor;
and
memory, coupled to the processor and storing instructions for identifying a safety zone for restricting movement of a robotic arm in an operating room,
wherein the processor is configured to:
receive an initiation input indicating initiation of defining of the safety zone;
in response to receiving the initiation input,
track an instrument using the tracking system,
determine a location of the tracked instrument relative to a reference point, and
detect changes in the location of the tracked instrument until a termination input is received at the medical navigation system, the termination input indicating termination of the defining of the safety zone;
and
store, in memory, change data indicative of the changes in the location of the tracked instrument, the data identifying a spatial position of the safety zone relative to the reference point,
wherein the safety zone is definable by at least one gesture instrument, and
wherein the safety zone is spatially shiftable if the reference point shifts.
