Kimberling-Rupp ovariectomy instrument. The instrument is introduced transvaginally into the peritoneal cavity, after which an ovary is placed in the oval window near the tip, by transsrectal manipulation. Next an internal shaft with a cutting edge is rotated to sever the ovary within the chamber. With a plunger the first ovary is pushed into the tip of the instrument, the window is re-opened and the second ovary is removed in the same manner. The instrument is primarily used for spaying feedlot heifers.
