The present disclosure provides for a surgical instrument which includes a housing and an endoscopic portion extending distally from the housing and defining a first longitudinal axis. The surgical instrument also includes an end effector disposed adjacent a distal portion of the endoscopic portion.
The present disclosure provides for a surgical instrument which includes a housing and an endoscopic portion extending distally from the housing and defining a first longitudinal axis. The surgical instrument also includes an end effector disposed adjacent a distal portion of the endoscopic portion. The end effector includes an anvil assembly and a cartridge assembly. The anvil assembly is pivotally coupled to the cartridge assembly to be movable from a first actuation position to at least one other second actuation position. The surgical instrument further includes a firing rod having a shaft defining a second longitudinal axis, the shaft having a cam member which is in mechanical cooperation with the anvil assembly and is configured to move the anvil assembly from the first actuation position to the at least one other second actuation position upon rotation of the firing rod about the second longitudinal axis.
1. A surgical instrument, comprising: a shaft defining a longitudinal axis therethrough and enclosing a drive motor, a shift motor, and a single drive gear, the drive motor mechanically cooperates with the shift motor to actuate the single drive gear; andan end effector connected to a distal end of
1. A surgical instrument, comprising: a shaft defining a longitudinal axis therethrough and enclosing a drive motor, a shift motor, and a single drive gear, the drive motor mechanically cooperates with the shift motor to actuate the single drive gear; andan end effector connected to a distal end of the shaft. 2. The surgical instrument of claim 1, wherein the drive motor enables rotation of the single drive gear. 3. The surgical instrument of claim 1, wherein the shift motor is configured to move the single drive gear in a plurality of positions. 4. The surgical instrument of claim 1, wherein the drive motor, the shift motor, and the single drive gear are disposed along the longitudinal axis defined by the shaft. 5. The surgical instrument of claim 1, wherein the drive motor is disposed adjacent the single drive gear. 6. The surgical instrument of claim 1, wherein the drive motor is separated from the shift motor by a housing having a first portion and a second portion, each of which is slidably engaged with the other. 7. The surgical instrument of claim 6, wherein the first portion is coupled to a drive motor casing of the drive motor and the second portion is coupled to the drive motor and is translatable within the shaft of the surgical instrument. 8. The surgical instrument of claim 7, further comprising a position lock configured to maintain the single drive gear in one of a plurality of positions, wherein the drive motor casing includes a plurality of slots, each of which is configured to mate with the position lock. 9. The surgical instrument of claim 8, wherein the position lock is spring-loaded and is biased against the drive motor casing. 10. The surgical instrument of claim 9, further comprising a shift sensor disposed adjacent the position lock, the shift sensor is configured to provide feedback relating to a position of the drive motor. 11. The surgical instrument of claim 10, further comprising at least one switch coupled to the shift motor and configured to communicate with the shift sensor, wherein the at least one switch is further configured to activate the shift motor based on a signal from the shift sensor. 12. A surgical instrument, comprising: a shaft including: a rigid portion defining a longitudinal axis and enclosing a drive motor, a shift motor, and a single drive gear having a drive end cap, the drive motor mechanically cooperates with the shift motor to actuate the single drive gear;a flexible portion having at least a first flexible segment and a second flexible segment, the first and second flexible segments being rotatably movable with respect to the other between a plurality of positions by rotation of the drive end cap, the drive end cap is configured to rotate continuously until each of the first and second flexible segments attains an articulated position; andan end effector disposed at a distal end of the flexible portion. 13. The surgical instrument of claim 12, wherein the drive motor enables rotation of the single drive gear. 14. The surgical instrument of claim 12, wherein the shift motor is configured to move the single drive gear in a plurality of positions. 15. The surgical instrument of claim 12, wherein the drive motor, the shift motor, and the single drive gear are disposed along the longitudinal axis defined by the rigid portion of the shaft. 16. The surgical instrument of claim 12, wherein the drive motor is disposed adjacent the single drive gear. 17. The surgical instrument of claim 12, wherein the drive motor is separated from the shift motor by a housing having a first portion and a second portion, each of which is slidably engaged with the other. 18. The surgical instrument of claim 17, wherein the first portion is coupled to a drive motor casing of the drive motor, and the second portion is coupled to the drive motor and is translatable within the shaft of the surgical instrument. 19. The surgical instrument of claim 18, further comprising a position lock configured to maintain the single drive gear in one of a plurality of positions, wherein the drive motor casing includes a plurality of slots, each of which is configured to mate with the position lock. 20. The surgical instrument of claim 19, wherein the position lock is spring-loaded and biased against the drive motor casing. 21. The surgical instrument of claim 20, further comprising a shift sensor disposed adjacent the position lock, the shift sensor is configured to provide feedback relating to a position of the drive motor.
