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

1. A surgical instrument, comprising:

a handle assembly;

a first elongated portion selectively connectable to a distal portion of the handle assembly and defining a longitudinal axis,

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

a first electronic component included on the handle assembly and a second electronic component included on the first elongated portion, the electronic components being configured to communicate with each other to determine the type of elongated portion that is engaged with the handle assembly.

2. The surgical instrument of claim 1, further comprising a second elongated portion selectively connectable to the distal portion of the handle assembly.

3. The surgical instrument of claim 2, further comprising a second end effector selectively connectable to a distal portion of at least one of the first elongated portion and the second elongated portion, the second end effector configured to perform a second function.

4. The surgical instrument of claim 1, wherein the first elongated portion is rotatable substantially about the longitudinal axis with respect to the handle assembly.

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

6. The surgical instrument of claim 5, wherein the first elongated portion includes a knob for allowing rotation of the first elongated portion with respect to the handle assembly, the conductive portion of the handle assembly being circular for allowing substantially continuous contact between the conductive portion and the contact during rotation of the first elongated portion with respect to the handle assembly.

7. The surgical instrument of claim 5, wherein the conductive portion of the handle assembly includes at least one conductive ring.

8. The surgical instrument of claim 7, wherein the at least one conductive ring is removable from the handle assembly.

9. The surgical instrument of claim 1, wherein at least one of the first elongated portion and the handle assembly includes structure for facilitating the selective connectability therebetween.

10. The surgical instrument of claim 1, further comprising a sensor included on the end effector, the sensor being configured to communicate with at least one of the first electronic component and the second electronic component to determine the type of end effector that is engaged with the first elongated portion.

11. A surgical instrument, comprising:

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

an elongated portion disposed in mechanical cooperation with a portion of the handle assembly and defining a longitudinal axis, the elongated portion including a contact for communicating electrical power with a conductive portion of the handle assembly, the contact of the elongated portion being displaced from a radial center of the elongated portion;

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

a second electronic component disposed on the first end effector, the second electronic component being configured to communicate with the first electronic component to determine the type of end effector that is engaged with the elongated portion.

12. The surgical instrument of claim 11, wherein the elongated portion is selectively connectable with the handle assembly.

13. The surgical instrument of claim 11, further comprising a second end effector selectively connectable with a distal portion of the elongated portion, the second end effector configured to perform a second surgical function.

14. The surgical instrument of claim 11, wherein the conductive portion of the handle assembly includes at least one conductive ring.

15. The surgical instrument of claim 14, wherein the at least one conductive ring is removable from the handle assembly.

16. The surgical instrument of claim 11, further comprising 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 that is engaged with the handle assembly.
