Abstract

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.

Claims

1. A control module for use with a surgical instrument, the control module comprising:

a storage unit for storing information relating to a force to be applied to different types of end effectors of the surgical instrument, wherein the control module is configured to measure at least one of voltage or current from a drive motor of the surgical instrument, wherein the control module is configured for receiving information from a first sensor relating to a type of shaft that is engaged with the surgical instrument, wherein the control module is configured for receiving information from a second sensor relating to the type of end effector that is engaged with the shaft, and wherein the control module is configured for receiving information from a third sensor relating to a longitudinal position of the drive motor.

2. The control module according to claim 1, wherein the control module is configured to control a force being applied to the end effector that is engaged with the shaft.

3. The control module according to claim 2, wherein the control module is configured to control the force being applied to the end effector that is engaged with the shaft depending on the type of end effector that is engaged with the shaft.

4. The control module according to claim 2, wherein the control module is configured to determine when the end effector is clamping tissue that exceeds a predetermined thickness.

5. The control module according to claim 4, wherein the control module includes an electric braking circuit configured to control the drive motor of the surgical instrument, and configured to control a shift motor of the surgical instrument associated with the third sensor.

6. The control module according to claim 1, wherein the control module is arranged to communicate with a video screen in an operating room.

7. The control module according to claim 1, wherein the control module is digital.

8. The control module according to claim 1, wherein the first sensor is configured to communicate with the second sensor.

9. A control module for use with a surgical instrument, wherein the control module is configured to measure at least one of voltage or current from a drive motor of the surgical instrument, wherein the control module receives information from a first sensor relating to a type of shaft engaged with the surgical instrument, from a second sensor of the surgical instrument, and from a third sensor relating to a longitudinal position of the drive motor.

10. The control module according to claim 9, wherein the information from the second sensor relates to a type of end effector engaged with the shaft.

11. The control module according to claim 10, wherein the control module is configured to control a force being applied to a firing rod of the surgical instrument depending on at least one of the voltage measurement or the current measurement from the drive motor.

12. The control module according to claim 10, wherein the control module includes a storage unit for storing information relating to a force to be applied to different types of end effectors.

13. The control module according to claim 9, wherein the first sensor is configured to communicate with the second sensor.
