Ovarian Ecraseur.

Ovarian Ecraseur.
This instrument can be used transvaginally (by colpotomy) to sever the ovarian pedicle. The curved tip, with a crush-cut blade, like an ecraseur, can be moved with the pistol grip handle as it slides within the square cuff of a second blade, as shown in the inset images. It is best to use this instrument on day 2 to 3 of the estrous cycle, when the ovarian blood supply is minimal.
