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 stapling instrument, comprising:

a handle assembly;

a first endoscopic portion selectively connectable to a distal portion of the handle assembly and defining a longitudinal axis, the first endoscopic portion including a housing adjacent a proximal portion of the first endoscopic portion, and an actuation member;

a motor disposed in mechanical cooperation with the housing of the first endoscopic portion, the motor being operatively connected to the actuation member for moving the actuation member substantially along the longitudinal axis;

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

a first sensor included on the handle assembly and a second sensor included on the first endoscopic portion, the sensors being configured to communicate with each other to determine the type of endoscopic portion that is engaged with the handle assembly.

2. The surgical stapling instrument of claim 1, wherein the first end effector is pivotably mounted so as to be pivotable away from the longitudinal axis.

3. The surgical stapling instrument of claim 1, wherein the first end effector includes an articulation link arranged for engagement with the actuation member, the articulation link being movable substantially along the longitudinal axis to pivot the first end effector away from the longitudinal axis.

4. The surgical stapling instrument of claim 1, wherein the housing of the first endoscopic portion includes a knob for being rotatably connected to the handle assembly.

5. The surgical stapling instrument of claim 1, wherein the housing of the first endoscopic portion includes an actuator operably connected to the actuation member.

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

7. The surgical stapling instrument of claim 6, further comprising a second end effector selectively connectable to a distal portion of at least one of the first endoscopic portion and the second endoscopic portion, the second end effector configured to perform a second stapling function.

8. The surgical stapling instrument of claim 7, wherein the first end effector includes an anvil assembly and a staple cartridge assembly, at least one of the anvil assembly and the staple cartridge assembly being pivotably movable with respect to the other, and wherein the second end effector includes a circular stapling assembly.

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

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

11. The surgical stapling instrument of claim 10, wherein the housing of the first endoscopic portion includes a knob for allowing rotation of the first endoscopic 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 endoscopic portion with respect to the handle assembly.

12. The surgical stapling instrument of claim 1, wherein the first endoscopic portion is configured and dimensioned for being selectively connectable to a distal portion of the handle assembly by a user of the surgical stapling instrument.

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

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

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

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