Abstract

The present disclosure provides a bipolar forceps. The bipolar forceps includes a housing having a handle assembly including a movable handle and one or more shafts. An end effector assembly operatively connects to a distal end of the shaft and includes a pair of first and second jaw members. A solenoid is in operative communication with the movable handle and operatively couples to a drive rod operatively coupled to at least one of the first and second jaw members for causing movement thereof. One or both of the first and second jaw members includes one or more teeth configured to engage one or more teeth located on the drive rod such that rotation of the solenoid imparts one of longitudinal and rotational movement of the drive rod such that at least one of the first and second jaw members moves between the open and closed positions.

Claims (32)

1. A surgical instrument, comprising:

a handle assembly;

at least one electromechanical device in operative communication with the handle assembly, the at least one electromechanical device adapted to connect to an energy source and configured to receive an actuation signal from the energy source when the handle assembly is actuated;

an end effector assembly operably coupled to the at least one electromechanical device to enable the at least one electromechanical device to impart movement of the end effector assembly from a first configuration to a second configuration;

at least one mechanical interface associated with the at least one electromechanical device; and

at least one corresponding mechanical interface associated with the end effector assembly and operably engaged with the at least one mechanical interface associated with the at least one electromechanical device such that, upon actuation of the handle assembly, the at least one electromechanical device receives the actuation signal and is energized to impart movement of the end effector assembly from the first configuration to the second configuration.

2. The surgical instrument according to claim 1 , wherein the end effector assembly includes first and second jaw members, at least one of the first and second jaw members movable relative to the other to move the end effector assembly from the first configuration to the second configuration.

3. The surgical instrument according to claim 1 , wherein the at least one mechanical interface includes a plurality of teeth, and wherein the at least one corresponding mechanical interface includes a corresponding plurality of teeth.

4. The surgical instrument according to claim 1 , wherein the at least one mechanical interface includes at least one cam pin, and wherein the at least one corresponding mechanical interface includes at least one corresponding cam slot.

5. The surgical instrument according to claim 1 , wherein the at least one electromechanical device includes a solenoid.

6. The surgical instrument according to claim 5 , wherein the solenoid is housed within the end effector assembly.

7. The surgical instrument according to claim 5 , wherein the at least one mechanical interface includes a protrusion at a distal end of the solenoid, and wherein the at least one corresponding mechanical interface is a corresponding opening configured to receive the protrusion.

8. The surgical instrument according to claim 1 , wherein the handle assembly includes a movable handle.

9. The surgical instrument according to claim 1 , further including a drive rod operably coupled between the at least one electromechanical device and the end effector assembly.

10. The surgical instrument according to claim 1 , wherein the end effector assembly is adapted to connect to the energy source for supplying energy to tissue.

11. A surgical system, comprising:

a surgical instrument, including:

a handle assembly;

at least one electromechanical device in operative communication with the handle assembly, the at least one electromechanical device adapted to connect to an energy source and configured to receive an actuation signal from the energy source when the handle assembly is actuated;

an end effector assembly operably coupled to the at least one electromechanical device to enable the at least one electromechanical device to impart movement of the end effector assembly from a first configuration to a second configuration;

at least one mechanical interface associated with the at least one electromechanical device; and

at least one corresponding mechanical interface associated with the end effector assembly and operably engaged with the at least one mechanical interface associated with the at least one electromechanical device such that, upon actuation of the handle assembly, the at least one electromechanical device receives the actuation signal and is energized to impart movement of the end effector assembly from the first configuration to the second configuration; and

an energy source in operative communication with the surgical instrument, the energy source having at least one algorithm for at least one of independently controlling or monitoring the delivery of energy from the energy source to the at least one electromechanical device and the end effector assembly.

12. The surgical system according to claim 11 , wherein the end effector assembly includes first and second jaw members, at least one of the first and second jaw members movable relative to the other to move the end effector assembly from the first configuration to the second configuration.

13. The surgical system according to claim 11 , wherein the at least one mechanical interface includes a plurality of teeth, and wherein the at least one corresponding mechanical interface includes a corresponding plurality of teeth.

14. The surgical system according to claim 11 , wherein the at least one mechanical interface includes at least one cam pin, and wherein the at least one corresponding mechanical interface includes at least one corresponding cam slot.

15. The surgical system according to claim 11 , wherein the at least one electromechanical device includes a solenoid.

16. The surgical system according to claim 15 , wherein the solenoid is housed within the end effector assembly.

17. The surgical system according to claim 15 , wherein the at least one mechanical interface includes a protrusion at a distal end of the solenoid, and wherein the at least one corresponding mechanical interface is a corresponding opening configured to receive the protrusion.

18. The surgical system according to claim 11 , wherein the handle assembly includes a movable handle.

19. The surgical system according to claim 11 , further including a drive rod operably coupled between the at least one electromechanical device and the end effector assembly.

20. The surgical system according to claim 11 , wherein the end effector assembly is adapted to connect to the energy source for supplying energy to tissue.
