4. A suction apparatus as recited in claim 1 wherein each of the suction tip extension members has a respective one of a plurality of different radial dimensions, so that each of the radial dimensions of the suction tip extension members is selected for receiving the corresponding respective one of the differently shaped electrocautery electrodes.
5. A suction apparatus as recited in claim 1 wherein the suction apparatus is adapted for receiving at least one electrode extender for alternatively coupling with one of the plurality of differently shaped electrocautery electrodes.
6. A suction apparatus as recited in claim 1 wherein at least one of the suction tip extension members is adapted for receiving at least one electrode extender for alternatively coupling with one of the plurality of differently shaped electrocautery electrodes.
7. A suction apparatus as recited in claim 1 further comprising an engagement member for releasably securing the suction apparatus to the electrosurgical pencil.
8. A suction apparatus as recited in claim 1 wherein the suction apparatus is separable from the electrosurgical pencil.
9. A suction apparatus as recited in claim 1 wherein the suction apparatus is disposable.
10. A suction apparatus as recited in claim 1 further comprising at least one movement limiting slot coupled with the housing for limiting movement of at least one of the differently shaped suction tip extension members to a preselected full extent over the corresponding respective one of the differently shaped electrocautery electrodes.
11. A suction apparatus as recited in claim 1 further comprising at least one movement limiting slot coupled with the housing for limiting at least one of:
movement of at least one of the differently shaped suction tip extension members to a preselected full extent over the corresponding respective one of the differently shaped electrocautery electrodes; and
movement of at least one of the differently shaped suction tip extension members to a preselected retraction extent over the corresponding respective one of the differently shaped electrocautery electrodes, so as to expose the corresponding respective one of the differently shaped electrocautery electrodes outside of at least one of the differently shaped suction tip extension members.
12. A suction apparatus for an electrosurgical pencil as recited in claim 1 further comprising:
a first movement limiting slot coupled with the housing for limiting movement of at least one of the differently shaped suction tip extension members to a preselected full extent over the corresponding respective one of the differently shaped electrocautery electrodes; and
an opposing movement limiting slot coupled with the housing for limiting movement of at least one of the differently shaped suction tip extension members to a preselected retraction extent over the corresponding respective one of the differently shaped electrocautery electrodes, so as to expose the corresponding respective one of the differently shaped electrocautery electrodes outside of at least one of the differently shaped suction tip extension members.
13. A suction attachment for an electrosurgical pencil that alternatively employs one of a plurality of differently shaped electrocautery electrodes comprising:
a plurality of differently shaped electrocautery electrodes;
a plurality of differently shaped suction tip extension members, wherein each of the differently shaped suction tip extension members is shaped for receiving a corresponding respective one of the differently shaped electrocautery electrodes;
an attachment housing for fluid coupling with one of the plurality of differently shaped suction tip extension members; and
an engagement member for releasably securing the suction attachment to the electrosurgical pencil.
14. A suction attachment as recited in claim 13 wherein the suction attachment is separable from the electrosurgical pencil.
15. A suction attachment as recited in claim 13 wherein the suction attachment is disposable.
16. A suction attachment as recited in claim 13 wherein the suction attachment is adapted for receiving at least one electrode extender for alternatively coupling with one of the plurality of differently shaped electrocautery electrodes.
17. A suction attachment as recited in claim 13 wherein at least one of the suction tip extension members is adapted for receiving at least one electrode extender for alternatively coupling with one of the plurality of differently shaped electrocautery electrodes.
