Abstract
Abstract A surgical instrument for performing gynecological procedures comprising a first forceps lever having a forwardly disposed section insertable into a vaginal cavity, an intermediate section and a rearwardly disposed handle section, a second forceps lever having a forwardly disposed section insertable into a vaginal cavity with the insertable section of the first forceps lever, an intermediate section pivotally connected to the intermediate section of the first forceps lever and a rearwardly disposed handle section cooperable with a handle section of the first forceps lever, the insertable section of the first forceps lever having a longitudinally disposed bore, a plunger member disposed in the longitudinally disposed bore and displaceable longitudinally therein, such plunger member being insertable in the uterine canal when the insertable sections of the forceps levers are inserted into a vaginal cavity, flexible material disposed on the plunger member and expandable to engage the wall of the uterine cavity and provide an expansive bearing contact therewith, and the insertable section of the second forceps lever having a lip portion engageable with the cervix of the uterus when the insertable sections of the forceps levers are inserted into a vaginal cavity, the plunger member is inserted in the uterine canal and the handle sections are moved together, thereby causing the uterine cervix to be clamped between the forceps levers.
