First Claim
Patent Images
1. An electro-cautery speculum comprising:
- a tube, said tube having an anterior end and a posterior end, said tube also having a top and a substantially opposite bottom;
a duct mounted on said tube, said duct having an inlet opening on the interior of said tube at the top thereof adjacent said anterior end and having an outlet adjacent the posterior end of said tube at the bottom thereof; and
a removable obturator at the anterior end of said tube, said removable obturator being removable through said tube and at said posterior end of said tube.

Abstract
Redundant wall retractor is tubular and is obturated for insertion. It has a duct which terminates in an opening at the top of the anterior end and terminates with a tube fitting at the bottom at the posterior end. It is made of dielectric synthetic polymer composition material, preferably transparent to retract tissues during loop electrode excision procedures with the duct positioned for withdrawing smoke.

12. An electro-cautery speculum comprising:
-
an inner tube, said inner tube having a posterior end and an anterior end, said inner tube having an opening therethrough from said posterior end to said anterior end, said inner tube having an axis extending from end to end and having a top side and a bottom side; walls at least partially in said inner tube defining a duct extending from adjacent said top at said anterior end to adjacent said bottom at said posterior end; and an obturator positioned within said anterior opening and removable through said inner tube out of said posterior end so that said speculum can be positioned with its obturator in place and the obturator can thereupon be removed for electro-cautery procedures. - View Dependent Claims (13, 14, 15, 16, 17)

18. The method of forming and using an electro-cautery speculum comprising the steps of:
-
forming a tubular speculum of dielectric transparent material with a smoke duct extending from its anterior to its posterior end; inserting the speculum with an obturator in place; withdrawing the obturator through the speculum; withdrawing gas from the upper anterior portion of the speculum out through the lower posterior portion of the speculum to aid in maintaining a clear visible field; and performing electro-cautery adjacent the anterior end of the speculum. - View Dependent Claims (19, 20)
