Powered surgical instrument
A surgical instrument including a housing, an endoscopic portion, a shaft portion and an end effector is disclosed. The endoscopic portion extends distally from the housing and defines a longitudinal axis. The shaft portion is selectively connectable to a distal end of the endoscopic portion. The end effector is selectively connectable to a distal end of the shaft portion.
1. A surgical instrument, comprising:
a drive gear rotatable about a drive gear axis and being selectively movable along the drive gear axis;
a drive motor including a drive motor shaft, the drive motor shaft being mechanically engaged with the drive gear and being configured to rotate the drive gear; and
a shift motor disposed in mechanical cooperation with the drive gear, the shift motor including a shift screw configured to move the drive gear along the drive gear axis.
2. The surgical instrument of claim 1 , further including an end effector disposed in mechanical cooperation with the drive gear.
3. The surgical instrument of claim 2 , wherein the shift motor is configured to move the drive motor along the drive gear axis.
4. The surgical instrument of claim 3 , further including a shift sensor associated with the shift motor and arranged to determine the position of the drive gear.
5. The surgical instrument of claim 4 , wherein the shift sensor is arranged to determine the longitudinal position of the drive motor.
6. The surgical instrument of claim 5 , wherein information from the shift sensor is communicated to a screen associated with the surgical instrument.
7. The surgical instrument of claim 6 , wherein the status of the shift motor is communicated to a screen associated with the surgical instrument.
8. The surgical instrument of claim 4 , wherein the shift sensor communicates with at least one switch to start or stop the shift motor.
9. The surgical instrument of claim 4 , further including a position lock for engaging the drive motor in one of a plurality of positions.
10. The surgical instrument of claim 9 , wherein the shift sensor interacts with the position lock to determine the status of the shift motor.
11. The surgical instrument of claim 2 , further including a housing that includes a screen for displaying information concerning a status of the surgical instrument.
12. The surgical instrument of claim 11 , wherein the screen is a touch screen.
13. The surgical instrument of claim 2 , further including at least one switch for controlling the surgical instrument.
14. The surgical instrument of claim 2 , the shift motor driving the shift screw to move the drive gear along the drive gear axis.
15. The surgical instrument of claim 14 , further comprising a screw housing, the shift screw being in engagement with the screw housing for moving the screw housing longitudinally.
16. A surgical instrument, comprising:
a drive gear rotatable about a drive gear axis and being selectively movable along the drive gear axis;
a drive motor including a drive motor shaft, the drive motor shaft being mechanically engaged with the drive gear and being configured to rotate the drive gear;
a shift motor disposed in mechanical cooperation with the drive gear and configured to move the drive gear and the drive motor along the drive gear axis; and
an end effector disposed in mechanical cooperation with the drive gear.
17. The surgical instrument of claim 16 , further including a shift sensor associated with the shift motor and arranged to determine the position of the drive gear.
18. The surgical instrument of claim 17 , wherein the shift sensor is arranged to determine the longitudinal position of the drive motor.
19. The surgical instrument of claim 16 , further including a housing that includes a screen for displaying information concerning a status of the surgical instrument.
20. A surgical instrument, comprising:
a drive gear rotatable about a drive gear axis and being selectively movable along the drive gear axis;
a drive motor including a drive motor shaft, the drive motor shaft being mechanically engaged with the drive gear and being configured to rotate the drive gear; and
a shift motor disposed in mechanical cooperation with the drive gear and configured to move the drive gear and the drive motor along the drive gear axis.
