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 electronic component disposed in electrical communication with the handle assembly;

an elongated portion having a distal portion and a proximal portion, and defining a longitudinal axis therebetween, the proximal portion being selectively connectable to the handle assembly;

a first end effector selectively connectable to the distal portion of 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 a type of end effector that is engaged with the elongated portion; 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 and the second electronic component to determine a type of elongated portion that is engaged with the handle assembly.

2. The surgical instrument of claim 1, further comprising a second end effector selectively connectable with the distal portion of 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 an electrical contact for communicating electrical power with a conductive portion of the handle assembly.

4. The surgical instrument of claim 3, wherein the elongated portion includes a knob for effecting rotation of the 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 thereof and the electrical contact of the elongated portion during rotation of the elongated portion with respect to the handle assembly.

5. The surgical stapling instrument of claim 4, wherein the at least one conductive ring of the handle assembly is removable.

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

7. The surgical instrument of claim 1, wherein the elongated portion includes an electrical contact disposed thereon for communicating electrical power with a conductive portion of the handle assembly, the electrical contact of the elongated portion being spaced a radial distance from a central axis of the elongated portion.

8. The surgical instrument of claim 1, wherein the end effector is pivotably mounted to the elongated portion so as to be pivotable relative to the longitudinal axis.

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