Electrosurgical device with vacuum port

1. An electrosurgical device comprising:

an electrode having a first portion with an exterior that is electrically uninsulated, a second portion with an exterior that is electrically insulated, and a third portion;

an elongated hollow body formed by a first member and a second member and having an internal cavity, the second member capable of rotating relative to the first member, the elongated hollow body having a front end, a rear end, an external surface, and an electrical wire arranged within the elongated hollow body,

wherein the second member is configured to reversibly receive the third portion of the electrode at the front end of the elongated hollow body such that electrical contact is made between the electrode and the electrical wire and the second portion of the electrode is not surrounded by the elongated hollow body;

a first button for controlling a current flow at a first level to the electrode and arranged on the external surface of the first member of the elongated hollow body;

a vacuum tube engaged by the second member of the elongated hollow body, wherein the vacuum tube is arranged adjacent to the electrode, the vacuum tube having a vacuum inlet; and

a vacuum outlet port arranged near the rear end and the first member, and

wherein the vacuum outlet port, internal cavity, and vacuum inlet are disposed in fluid communication with each other,

wherein the first member has an end with an opening facing the second member, the opening including a first engagement surface, the second member has a first end and a second end, the second member having a first portion having an outside diameter sized to fit inside the opening in the first member and a flange at the second end, the second member having a second engaging surface disposed near the second end, the second engaging surface configured to engage with the first engagement surface to prevent rotation of the second member relative to the first member and the vacuum outlet port when the flange is acted on by a biasing member,

wherein the second member is operable to rotate relative to the first member and the vacuum outlet port when the biasing member is compressed by the flange, and

wherein the vacuum outlet port, the internal cavity, and the vacuum inlet maintain fluid communication between one another regardless of a rotational position of the first member with respect to the second member.

2. An electrosurgical device as set forth in claim 1 wherein the elongated hollow body is ergonomically shaped to be received by a user's hand.

3. An electrosurgical device as set forth in claim 1 , wherein the biasing member comprises a coil spring disposed between the flange on the second member and the shoulder on the first member.

4. An electrosurgical device as set forth in claim 1 wherein the electrode is monopolar, bipolar, or sesquipolar.

5. An electrosurgical device as set forth in claim 1 and further comprising a second button for controlling a current flow at a second level to the electrode.

6. An electrosurgical device as set forth in claim 5 and further comprising a third button for controlling a vacuum source.

7. An electrosurgical device as set forth in claim 1 and further comprising:

a light source arranged to illuminate an area near the electrode;

a battery for providing power to the light source; and,

a button for controlling the light.

8. An electrosurgical device as set forth in claim 1 and further a swivel joint between the elongated hollow body and the outlet port; and wherein the electrical wire passes through the swivel joint.

9. An electrosurgical device as set forth in claim 1 further comprising a filter having an RFID tag containing filter information.

10. An electrosurgical device as set forth in claim 1 wherein the vacuum inlet has a substantially rectangular cross section.

11. An electrosurgical device comprising:

an electrode having a first portion with an exterior that is electrically uninsulated, a second portion with an exterior that is electrically insulated, and a third portion;

an elongated hollow body formed by a first member and a second member and having an internal cavity, the second member capable of rotating relative to the first member, wherein the first member has an end facing the second member, the end having an opening with a first diameter, the first member having a chamber defined therein, the chamber having a second diameter larger than the first diameter, the chamber bordered by a side wall and a shoulder extending from the side wall and the opening, the chamber bordered by a bottom wall with a first engagement surface disposed thereon, the chamber disposed in fluid communication with the cavity, wherein the second member has a first end and a second end, the second member having a first portion having an outside diameter sized to fit inside the opening in the first member and a flange at the second end, the second member having a second engaging surface disposed near the second end, the second engaging surface configured to engage with the first engagement surface to prevent rotation between the first member and the second member when the flange is acted on by a biasing member, wherein the second member is operable to rotate relative to the first member when the biasing member is compressed by the flange, the elongated hollow body having a front end, a rear end, an external surface, and an electrical wire arranged within the elongated hollow body, the second member configured to reversibly receive the third portion of the electrode at the front end of the elongated hollow body such that electrical contact is made between the electrode and the electrical wire and the second portion of the electrode is not surrounded by the elongated hollow body;

a first button for controlling a current flow at a first level to the electrode and arranged on the external surface of the first member of the elongated hollow body;

a vacuum tube engaged by the elongated hollow body on the second member and arranged adjacent the electrode, the vacuum tube having a vacuum inlet; and

a vacuum outlet port arranged near the rear end, and

wherein the outlet port, internal cavity, and vacuum inlet are disposed in fluid communication with each other, and wherein the outlet port, the internal cavity, and the vacuum inlet maintain fluid communication between one another regardless of a rotational position of the first member with respect to the second member.

12. An electrosurgical device as set forth in claim 11 wherein the elongated hollow body is pencil shaped.

13. An electrosurgical device as set forth in claim 11 wherein the electrode is monopolar, bipolar, or sesquipolar.

14. An electrosurgical device as set forth in claim 11 and further comprising a second button for controlling a current flow at a second level to the electrode.

15. An electrosurgical device as set forth in claim 14 and further comprising a third button for controlling a vacuum source.

16. An electrosurgical device as set forth in claim 11 wherein the vacuum inlet has a substantially rectangular cross section.
