Abstract

An end effector assembly for a forceps includes jaws, a cutting assembly, and at least one cam assembly. At least one jaw is moveable relative to the other about a pivot between open and closed positions for grasping tissue. At least one jaw includes a control trough that extends therealong. The pivot has first and second pivot bosses defining a pivot hole therebetween. The cutting assembly includes a blade and blade control portion, and defines a longitudinal axis through the blade and the control portion. The control portion slidably translates through the pivot hole defined between the pivot bosses to allow selective advancement thereof through the trough. The blade is disposed distally of the pivot and extends farther from the axis than an outer surface of the control portion. The cam assembly is coupled to the moveable jaw and is actuatable to move the movable jaw between the positions.

Claims

1. A cordless Radio-Frequency (RF) surgical device, comprising:

a handle including a handle body and an aseptically sealable compartment;

a shaft extending distally from the handle body;

an end effector extending from a distal portion of the shaft, the end effector including first and second jaws relatively movable between an open position and a closed position to grasp tissue, and first and second bipolar contacts associated with the first and second jaws;

an RF generator sealed within the handle body, the RF generator including an RF signal-generating circuit and a control circuit configured to control an output of the RF signal-generating circuit, the output of the RF signal-generating circuit electrically coupled to the first and second bipolar contacts and configured to supply bipolar RF energy to first and second bipolar contacts for conduction between the first and second jaws to treat grasped tissue; and

a battery configured for removable receipt within the aseptically sealable compartment, wherein the battery is electrically coupled to the RF generator when received within aseptically sealable compartment to enable the battery to power the RF generator.

2. The cordless RF surgical device according to claim 1, further comprising a casing housing the RF generator therein, the casing configured to removably engage the handle body.

3. The cordless RF surgical device according to claim 1, wherein the handle body further includes a door movable between an open position, permitting insertion of the battery into and removal of the battery from the aseptically sealable compartment, and a closed position, sealing the aseptically sealable compartment.

4. The cordless RF surgical device according to claim 1, further comprising:

a cutting blade selectively translatable relative to the end effector between a retracted position and an extended position for cutting grasped tissue; and

a cutting blade trigger operably associated with the handle body and coupled to the cutting blade such that actuation of the cutting blade trigger translates the cutting blade from the retracted position to the extended position.

5. The cordless RF surgical device according to claim 1, further comprising an energy-activation trigger coupled to the handle body and configured to enable the selective supply of bipolar RF energy to the first and second bipolar contacts of the end effector.

6. The cordless RF surgical device according to claim 1, further comprising a battery eject assembly operably associated with the aseptically sealable compartment and configured to facilitate ejection of the battery therefrom.

7. A cordless Radio-Frequency (RF) surgical device, comprising:

a handle including a handle body and an aseptically sealable compartment;

a shaft extending distally from the handle body;

an end effector extending from a distal portion of the shaft, the end effector including first and second jaws relatively movable between an open position and a closed position to grasp tissue, and first and second bipolar contacts associated with the first and second jaws;

an RF generator sealed within the handle body, the RF generator including an RF signal-generating circuit and a control circuit configured to control an output of the RF signal-generating circuit, the output of the RF signal-generating circuit electrically coupled to the first and second bipolar contacts and configured to supply bipolar RF energy to first and second bipolar contacts for conduction between the first and second jaws to treat grasped tissue; and

a battery disposed within the aseptically sealable compartment, wherein the battery is electrically coupled to the RF generator to enable the battery to power the RF generator.

8. The cordless RF surgical device according to claim 7, further comprising a casing housing the RF generator therein, the casing configured to removably engage the handle body.

9. The cordless RF surgical device according to claim 7, wherein the handle body further includes a door movable between an open position, permitting insertion of the battery into and removal of the battery from the aseptically sealable compartment, and a closed position, sealing the aseptically sealable compartment.

10. The cordless RF surgical device according to claim 7, further comprising:

a cutting blade selectively translatable relative to the end effector between a retracted position and an extended position for cutting grasped tissue; and

a cutting blade trigger operably associated with the handle body and coupled to the cutting blade such that actuation of the cutting blade trigger translates the cutting blade from the retracted position to the extended position.

11. The cordless RF surgical device according to claim 7, further comprising an energy-activation trigger coupled to the handle body and configured to enable the selective supply of bipolar RF energy to the first and second bipolar contacts of the end effector.

12. A cordless Radio-Frequency (RF) surgical device, comprising:

a handle including a handle body;

a shaft extending distally from the handle body;

an end effector extending from a distal portion of the shaft, the end effector including first and second jaws relatively movable between an open position and a closed position to grasp tissue, and first and second bipolar contacts associated with the first and second jaws; and

an RF generator sealed within the handle body, the RF generator including an RF signal-generating circuit and a control circuit configured to control an output of the RF signal-generating circuit, the output of the RF signal-generating circuit electrically coupled to the first and second bipolar contacts and configured to supply bipolar RF energy to first and second bipolar contacts for conduction between the first and second jaws to treat grasped tissue,

wherein the handle further includes an aseptically sealable compartment configured to aseptically seal a battery therein, the battery configured to be electrically coupled to the RF generator when received within aseptically sealable compartment to enable the battery to power the RF generator.

13. The cordless RF surgical device according to claim 12, further comprising a casing housing the RF generator therein, the casing configured to removably engage the handle body.

14. The cordless RF surgical device according to claim 12, wherein the handle body further includes a door movable between an open position, permitting insertion of the battery into and removal of the battery from the aseptically sealable compartment, and a closed position, sealing the aseptically sealable compartment.

15. The cordless RF surgical device according to claim 12, further comprising:

a cutting blade selectively translatable relative to the end effector between a retracted position and an extended position for cutting grasped tissue; and

a cutting blade trigger operably associated with the handle body and coupled to the cutting blade such that actuation of the cutting blade trigger translates the cutting blade from the retracted position to the extended position.

16. The cordless RF surgical device according to claim 12, further comprising an energy-activation trigger coupled to the handle body and configured to enable the selective supply of bipolar RF energy to the first and second bipolar contacts of the end effector.
