Abstract
An orthopaedic surgical instrument system includes an orthopaedic surgical instrument tray and an orthopaedic surgical instrument that is configured to be positioned in the instrument tray. The orthopaedic surgical instrument system also includes a machine-readable optical label that is associated with the instrument. The system is configured to determine a duration of use of the instrument based on whether the machine-readable optical label is detected.
Claims18
An orthopaedic surgical instrument system, the system comprising:
- an orthopaedic surgical instrument tray,
- an orthopaedic surgical instrument configured to be positioned in the instrument tray,
- a machine-readable optical label positioned in the instrument tray and associated with the instrument,
- an imaging device operable to read the optical label, and
- an electronic controller including (i) a processor operable to receive output signals from the imaging device and (ii) a memory device,
- wherein the optical label is sized to be covered by the instrument when the instrument is positioned in the instrument tray, and
- wherein the memory device includes a plurality of instructions that, when read by the processor, cause the processor to:
- (i) detect, based on the output signals from the imaging device, the optical label when the instrument is removed from the instrument tray,
- (ii) interpret the optical label to identify the instrument and record a first time indicating that the instrument is removed from the instrument tray,
- (iii) record, based on the output signals from the imaging device, a second time when the optical label is no longer detected, and
- (iv) compare the first time to the second time to determine a duration of use of the instrument.
An orthopaedic surgical instrument system, the system comprising:
- an orthopaedic surgical instrument,
- a machine-readable optical label associated with the instrument,
- an imaging device operable to read the optical label, and
- an electronic controller including (i) a processor operable to receive output signals from the imaging device and (ii) a memory device,
- wherein the memory device includes a plurality of instructions that, when read by the processor, cause the processor to:
- (i) detect, based on the output signals from the imaging device, the optical label when the instrument is in use,
- (ii) interpret the optical label to identify the instrument and record a first time indicating that the instrument is in use,
- (iii) record, based on the output signals from the imaging device, a second time when the instrument is no longer in use, and
- (iv) compare the first time to the second time to determine a duration of use of the instrument, and
- wherein the instrument tray further includes a body and lid hinged to the body, wherein the chamber is formed in the body, and the imaging device is positioned in the lid, the lid configured to angle relative to the body so that the imaging device is angled toward the optical label.
A method of determining a duration of use of an orthopaedic surgical instrument, the method comprising:
- detecting a machine-readable optical label associated with an orthopaedic surgical instrument when the instrument is in use,
- interpreting the optical label to identify the instrument when the instrument is in use,
- determining when the optical label is no longer detected, and
- determining a duration of use of the instrument based on when the optical label was detected,
- wherein when the instrument is not in use the instrument is positioned over the optical label such that the optical label is unreadable, the method further comprising detecting the optical label when the optical label becomes readable as the instrument is removed from the optical label.
