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 system, comprising

a housing assembly;

an endoscopic portion selectively connectable to the housing assembly;

a shaft portion having a distal end and a proximal end, the proximal end being selectively connectable to the endoscopic portion, the shaft portion being a unique type of shaft portion;

a first end effector selectively connectable to the distal end of the shaft portion, the first end effector configured to perform a first surgical function, the first end effector being a unique type of first end effector;

a first electronic component disposed in electrical communication with the endoscopic portion;

a second electronic component disposed on the shaft portion and in electrical communication with the first electronic component, the second electrical component being configured to communicate with the first electronic component to determine the type of shaft portion that is engaged with the endoscopic portion; and

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

2. The surgical instrument system according to claim 1, further including a user interface, the user interface being disposed on a proximal portion of the housing assembly.

3. The surgical instrument system according to claim 2, wherein the user interface includes a screen, the screen displaying information gathered by the first electronic component, the second electronic component, and the third electronic component.

4. The surgical instrument system according to claim 1, wherein the information gathered by the first electronic component, the second electronic component and the third electronic component is transmitted to a receiver for an operating room monitoring system.

5. The surgical instrument system according to claim 1, wherein the shaft portion includes an articulatable section.

6. The surgical instrument system according to claim 1, wherein the shaft portion includes a curved section.

7. The surgical instrument system according to claim 1, wherein the shaft portion is composed of a compliant material.

8. The surgical instrument system according to claim 1, further comprising a second end effector.

9. The surgical instrument system according to claim 8, wherein the second end effector is selectively connectable to the distal end of the shaft portion, the second end effector configured to perform a second surgical function.

10. The method of using a surgical device, comprising:

providing a surgical device including;

a housing assembly;

an endoscopic portion selectively connectable to the housing assembly;

a plurality of shaft portions each having a distal end and a proximal end, the proximal end being selectively connectable to the endoscopic portion;

a plurality of end effectors each selectively connectable to the distal end of the plurality of shaft portions, each end effector of the plurality of end effectors performs a unique surgical function;

a first electronic component disposed in electrical communication with the endoscopic portion;

a second electronic component disposed on the shaft portion and in electrical communication with the first electronic component, the second electrical component being configured to communicate with the first electronic component to determine a type of shaft portion that is engaged with the endoscopic portion;

a third electronic component disposed on the plurality of end effectors, the third electrical component being configured to communicate with the second electronic component to determine a type of end effector that is engaged with the shaft portion;

a user interface, the user interface positioned on a proximal portion of the housing assembly, wherein the user interface displays information gathered by the first electronic component, the second component, and the third component;

selecting a shaft portion from the plurality of shaft portions;

connecting the selected shaft portion to the endoscopic portion;

selecting an end effector from the plurality of end effectors;

connecting the selected end effector to the selected shaft portion; and

evaluating the information displayed on the user interface.

11. The method of use according to claim 10, wherein selecting the shaft portion includes selecting a shaft portion from a group including a shaft portion having an articulable section, a shaft portion having a curved section, and a shaft portion composed of compliant material.

12. The method of use according to claim 10, wherein selecting the end effector includes selecting an end effector from a group including a circular cartridge assembly, a pivotable cartridge assembly, and a parallel jaw member assembly.

13. The method of use according to claim 10, further comprising displaying information on the user interface related to the selected shaft portion, the selected end effector or both.
