Olsen-Hegar Needle Holder Purpose. Holding surgical needles. Features. This popular type of needle holder combines a ring han- dled needle holder with inte- grated suture scissors proximal to the jaws. Olsen-Hegar needle holders are preferred by some surgeons who operate without assistants, since the surgeon can hold the surgical needle and cut the suture material without changing instruments. This needle holder can improve speed and efficiency, but one disadvantage is that the sur- geon may inadvertently cut the suture material. Olsen-Hegar needle holders have rounded tips and flat, tapered, finely ser- rated jaws. They are available in a variety of handle lengths. The needle holder has longi- tudinal grooves on the grasp- ing surface to accommodate the curve of the suture needle. Carbide inserts are available to increase grip on the needle and improve durability of the jaws.
Volkmann Retractor Purpose. Separating incised tis- sues or retracting tendons and/or muscles to expose deeper structures.
Features. The Volkmann retractor is an instrument shaped like a curved kitchen fork with two to six prongs that curl back on themselves halfway along their length. It is available in both a finger (i.e., just the forks) and a handheld model that has either a hollow or ringed handle.

Covault Spay Hook Purpose. Localization and mobilization of the uterus and ovaries dur- ing an ovariohysterectomy.
Features. This is a thin, long-handled, probe-like instrument that is shaped like a shepherd’s hook with a round or octagonal handle and a curved, rounded button tip. This spay hook is passed through a small abdom- inal incision to locate and hook the suspensory ligament, broad ligament, or body of the uterus and subsequently deliver the uterus and ovaries through the incision for excision.
