Abstract

A surgical instrument including a handle assembly, a first endoscopic portion, a motor, and a first end effector is disclosed. The first endoscopic portion is selectively connectable to a distal portion of the handle assembly and defines a longitudinal axis. The first endoscopic portion includes a housing adjacent its proximal portion and includes an actuation member. The motor is disposed in mechanical cooperation with the housing of the first endoscopic portion and is operatively connected to the actuation member for moving the actuation member substantially along the longitudinal axis. The first end effector is selectively connectable to a distal portion of the first endoscopic portion and is configured to perform a first stapling function.

Claims (23)

1. A surgical instrument, comprising:

a first electronic component;

an elongated portion;

a first end effector selectively connectable to the elongated portion, the first end effector configured to perform a first surgical function;

a second electronic component disposed on the first end effector and in electrical communication with the first electronic component, the second electronic component being configured to communicate with the first electronic component to determine the type of end effector; and

a third electronic component included on the elongated portion, the third electronic component being configured to communicate with at least one of the first electronic component and the second electronic component to determine the type of elongated portion.

2. The surgical instrument of claim 1 , further comprising a second end effector selectively connectable with the elongated portion, the second end effector configured to perform a second surgical function.

3. The surgical instrument of claim 1 , wherein the elongated portion includes a contact for communicating electrical power with a conductive portion of a handle assembly.

4. The surgical instrument of claim 3 , wherein the conductive portion of the handle assembly includes at least one conductive ring.

5. The surgical instrument of claim 4 , wherein the at least one conductive ring of the handle assembly is disposed adjacent a distal portion of the handle assembly.

6. The surgical instrument of claim 4 , wherein the at least one conductive ring is disposed around a distal portion of the handle assembly.

7. The surgical instrument of claim 4 , wherein the elongate portion is rotatably couplable to the handle assembly along a longitudinal axis of the handle assembly.

8. The surgical instrument of claim 7 , wherein the at least one conductive ring is further configured to facilitate continuous electrical communication between the handle assembly and the elongate portion during rotation therebetween.

9. The surgical instrument of claim 3 , wherein the at least one conductive ring of the handle assembly is further configured to be removeably couplable to the handle assembly.

10. The surgical instrument of claim 3 , wherein the conductive portion of the handle assembly is further configured to electrically communicate with at least one of a power source or a micro controller.

11. The surgical instrument of claim 10 , wherein the power source is at least one of an internal power source disposed in the handle assembly or an external power source disposed externally of the handle assembly.

12. A surgical instrument, comprising:

a first electronic component disposed in electrical communication with a handle assembly;

an elongated portion selectively connectable at a proximal portion thereof to a handle assembly;

a first end effector selectively connectable to a distal portion of the elongated portion;

a second electronic component disposed on the first end effector and in electrical communication with the first electronic component, the second electronic component being configured to communicate with the first electronic component to determine a first set of data from the first end effector; and

a third electronic component disposed on the elongated portion, the third electronic component being configured to communicate with at least one of the first electronic component or the second electronic component to determine a second set of data from the elongated portion.

13. The surgical instrument of claim 12 , wherein the first set of data from the first end effector includes at least one of a function of the first end effector, an identification of the first end effector, or an operational status of the first end effector.
