Limited reuse ablation needles and ablation devices for use therewith
A surgical instrument includes a reusable component and a limited-use component releasably engagable with the reusable component. The limited-use component is configured for one or more uses and includes a clocking mechanism configured to count each engagement of the reusable component and the limited-use component to one another. The clocking mechanism is incrementally transitionable upon each successive count from one or more uses state, wherein the clocking mechanism permits both mechanical engagement and electrical coupling of the reusable component and the limited-use component to one another, to a spent state, wherein the clocking mechanism inhibits both mechanical engagement and electrical coupling of the limited-use component and the reusable component to one another.
1. A surgical instrument, comprising:
a reusable component configured to connect to a source of fluid; and
a limited-use component releasably engagable with the reusable component, the limited-use component configured to receive fluid from the reusable component, the limited-use component including a clocking mechanism configured to count each successive use of the limited-use component upon supply of fluid to the limited-use component, the clocking mechanism incrementally transitionable upon each successive count from at least one use state, wherein the clocking mechanism permits coupling of the reusable component and the limited-use component to one another, to a spent state, wherein the clocking mechanism inhibits coupling of the reusable component and the limited-use component to one another.
2. The surgical instrument according to claim 1 , wherein, in the at least one use state, the clocking mechanism permits both mechanical engagement and electrical communication between the reusable component and the limited-use component, and wherein, in the spent state, the clocking mechanism inhibits both mechanical engagement and electrical communication between the reusable component and the limited-use component.
3. The surgical instrument according to claim 1 , wherein the limited-use component is configured for a pre-determined plurality of uses, and wherein the clocking mechanism is incrementally transitionable from a plurality of use states, each corresponding to one of the pre-determined plurality of uses, to the spent state.
4. The surgical instrument according to claim 1 , wherein the clocking mechanism includes a hub and a housing, the hub disposed within the housing and rotatably and longitudinally movable relative to the housing to incrementally transition the clocking mechanism from the at least one use state to the spent state.
5. The surgical instrument according to claim 1 , wherein the clocking mechanism further includes indicia configured to display a condition of the limited-use component.
6. The surgical instrument according to claim 5 , wherein the indicia displays a number of uses remaining for the limited-use component.
7. The surgical instrument according to claim 1 , wherein the reusable component is a handle assembly.
8. The surgical instrument according to claim 7 , wherein the limited-use component is an electrode assembly releasably engagable with the handle assembly.
9. A surgical instrument, comprising:
a reusable component configured to connect to a source of fluid; and
a limited-use component configured to supply energy to tissue, the limited-use component releasably engagable with the reusable component and configured to receive fluid from the reusable component when engaged therewith to cool the limited-use component, the limited-use component including a clocking mechanism configured to count each successive use of the limited-use component upon supply of fluid to the limited-use component, the clocking mechanism incrementally transitionable upon each successive count from at least one use state, wherein the clocking mechanism permits coupling of the reusable component and the limited-use component to one another, to a spent state, wherein the clocking mechanism inhibits coupling of the reusable component and the limited-use component to one another.
10. The surgical instrument according to claim 9 , wherein, in the at least one use state, the clocking mechanism permits mechanical engagement between the reusable component and the limited-use component, and wherein, in the spent state, the clocking mechanism inhibits mechanical engagement between the reusable component and the limited-use component.
11. The surgical instrument according to claim 9 , wherein, in the at least one use state, the clocking mechanism permits electrical communication between the reusable component and the limited-use component, and wherein, in the spent state, the clocking mechanism inhibits electrical communication between the reusable component and the limited-use component.
12. The surgical instrument according to claim 9 , wherein the limited-use component is configured for a pre-determined plurality of uses, and wherein the clocking mechanism is incrementally transitionable from a plurality of use states, each corresponding to one of the pre-determined plurality of uses, to the spent state.
