Abstract
Systems, devices and methods for managing surgical instruments throughout their lifecycle include disabling a usage based device lockout and providing notifications for devices nearing a usage based lockout. A device adaptor connected inline between a surgical instrument and a power source can be configured to alter a device EEPROM to allow for additional device usage despite a usage based lockout. Notifications and user prompts may be displayed requiring a user to acknowledge that a usage based device lockout has occurred in order to avoid an attempt to use an expired device in a future procedure.
Claims20
An apparatus, comprising:
- (a) a surgical generator comprising an instrument receptacle and a display;
- and
- (b) a surgical instrument comprising a generator connection and an instrument indicator, the generator connection adapted to be connected to the instrument receptacle,
- wherein the surgical generator is configured to, upon being connected to the surgical instrument, receive a set of usage data from a memory of the surgical instrument,
- wherein the surgical generator is configured to determine if the set of usage data indicates that the surgical instrument will become inoperable after being used for a present procedure,
- wherein the surgical generator is configured to receive a signal indicating that the surgical instrument is no longer in use,
- wherein the surgical generator is configured to, in response to a determination that the surgical instrument will become inoperable and the signal indicating that the surgical instrument is no longer in use, provide a notification that the surgical instrument is inoperable for subsequent uses, and
- wherein the instrument indicator is configured to activate in response to the determination that the surgical instrument will become inoperable and the signal indicating that the surgical instrument is no longer in use.
5 more elements
An apparatus, comprising:
- (a) a surgical generator comprising an instrument receptacle and a display;
- (b) a surgical instrument comprising a generator connection and a memory;
- and
- (c) an adaptor, the adaptor comprising a first end, a second end, and an override chip, wherein the first end of the adaptor is shaped to fit the instrument receptacle, wherein the second end of the adapter is shaped to fit the generator connection, wherein the surgical generator is configured to connect to the surgical instrument via the adaptor,
- wherein the surgical generator is further configured to, upon being connected to the surgical instrument, receive a set of usage data from the memory of the surgical instrument,
- wherein the surgical generator is further configured to determine if the set of usage data indicates that the surgical instrument will become inoperable after being used for a present procedure,
- wherein the surgical generator is further configured to receive a signal indicating that the surgical instrument is no longer in use,
- wherein the surgical generator is further configured to, in response to a determination that the surgical instrument will become inoperable and the signal indicating that the surgical instrument is no longer in use, provide a notification that the surgical instrument is inoperable for subsequent uses,
- wherein the adaptor is configured to modify the set of usage data on the memory and reduce a usage indicator of the set of usage data, and
- wherein the surgical instrument is configured to become operable in response to the usage indicator being reduced by the adaptor.
7 more elements
A method of providing a notification from a surgical instrument, comprising:
- (a) connecting the surgical instrument to a surgical generator;
- (b) at the surgical generator, receiving a set of usage data from a memory of the surgical instrument;
- (c) determining if the set of usage data indicates that the surgical instrument will become inoperable after being used for a present procedure;
- (d) receiving a signal indicating that the surgical instrument is no longer in use;
- (e) in response to a determination that the surgical instrument will become inoperable and the signal indicating that the surgical instrument is no longer in use, providing the notification that the surgical instrument is inoperable for subsequent uses;
- and
- (f) automatically activating a usability indicator on the surgical instrument to indicate that the surgical instrument is inoperable for subsequent uses.
