Abstract

The present disclosure provides a bipolar forceps adapted to connect to a source of electrosurgical energy for performing an electrosurgical procedure. The bipolar forceps includes a housing having a shaft that extends therefrom. The bipolar forceps is in operative communication with one or more vacuum sources. The bipolar forceps includes an end effector assembly having a pair of first and second jaw members biased in an open configuration; each jaw member including a respective seal plate. The pair of first and second jaw members is operatively and pivotably connected to a distal end of the shaft. One or both of the first and second jaw members includes one or more apertures in fluid communication with the distal end of the shaft and the one or more vacuum sources.

Claims

1. A forceps adapted to connect to a source of electrosurgical energy for performing an electrosurgical procedure, the forceps comprising:

a housing having a shaft that extends therefrom;

at least one vacuum source in operative communication with the forceps; and

an end effector assembly having a pair of first and second jaw members biased in an open configuration and each including a respective seal plate, the pair of first and second jaw members operatively and pivotably connected to a distal end of the shaft,

wherein at least one of the first and second jaw members includes at least one aperture in fluid communication with the distal end of the shaft and the at least one vacuum source, the at least one vacuum source configured to act as a single actuator, without other internal and external actuating mechanisms, for drawing the first and second jaw members toward one another from the open configuration to a closed configuration for grasping and subsequently treating tissue.

2. The forceps according to claim 1, further including a control system in operative communication with the forceps and configured to control the at least one vacuum source.

3. The forceps according to claim 2, wherein the control system includes at least one sensor in operative communication with the at least one vacuum source configured to control fluid flow through the at least one aperture.

4. The forceps according to claim 1, further including a seal structure configured to provide a substantially air tight seal between the pair of jaw members and the distal end of the shaft.

5. The forceps according to claim 1, wherein each of the first and second jaw members defines a channel extending from the at least one aperture located on each of the first and second jaw members to the distal end of the shaft.

6. The forceps according to claim 5, wherein the forceps further includes a vacuum tube feed path configured to house a vacuum tube in fluid communication with the vacuum source and the channel of each in the jaw members.

7. The forceps according to claim 6, wherein the vacuum tube operatively couples to a proximal end of the forceps and extends therethrough to the proximal end of each of the first and second jaw members.

8. The forceps according to claim 1, wherein the at least one aperture on each of the first and second jaw members is disposed along the seal plates of each of the jaw members.

9. The forceps according to claim 3, wherein the at least one vacuum source is activated by a switch in operative communication with the forceps.

10. The forceps according to claim 1, wherein the at least one aperture is at least one pair of apertures, where each of the pair of apertures includes one aperture in the first jaw member and the other aperture in the second jaw member, the apertures disposed at predetermined locations along an entire length of an inner surface of the first and second jaw members.

11. A system for performing an electrosurgical procedure, comprising:

a bipolar forceps, comprising;

a housing having a shaft that extends therefrom;

at least one vacuum source in operative communication with the shaft;

an end effector assembly having a pair of first and second jaw members biased in an open configuration and each including a respective seal plate, the pair of first and second jaw members operatively and pivotably connected to a distal end of the shaft,

wherein the first and second jaw members each include at least one aperture in fluid communication with the distal end of the shaft and the at least one vacuum source, the at least one vacuum source configured to act as a single actuator, without other internal and external actuating mechanisms, for drawing the first and second jaw members toward one another from the open configuration to a closed configuration for grasping and subsequently treating tissue; and

a control system in operative communication with the bipolar forceps and having at least one algorithm for at least one of independently controlling and monitoring the delivery of electrosurgical energy from the source of electrosurgical energy to the tissue sealing plate on each of the jaw members and controlling and monitoring fluid flow to and through each of the first and second jaw members to regulate the closure pressure between the jaws.

12. The system according to claim 11, wherein the control system includes at least one sensor in operative communication with one of the at least one vacuum source and the source of electrosurgical energy for controlling fluid flow to and through each of the first and second jaw members.

13. The system according to claim 11, wherein the at least one aperture is at least one pair of apertures, where each of the pair of apertures includes one aperture in the first jaw member and the other aperture in the second jaw member, the apertures disposed at predetermined locations along an entire length of an inner surface of the first and second jaw members.
