Instrumentation

Forceps

A number of forceps are available. Atraumatic forceps include the Adson and DeBakey instruments. For lymph node and fat dissection, for example, obturator fossa dissection, ring forceps are quite acceptable. Rat-tooth forceps are excellent for traction and for holding tissue securely; however, they may traumatize skin and other delicate tissues. Adson-Brown forceps are the best instruments for grasping skin edges during closure procedures ( Fig. 4.1A to C ). For fine work deep in the pelvis, for example, dissecting around the ureter or iliac vessels, I prefer a bayonet forceps equipped with a brown-toothed tip ( Fig. 4.1D and E ).

Clamps

Clamps may be subdivided into grasping and traction clamps, which include Allis and Ochsner clamps. Grasping clamps are relatively atraumatic, whereas traction clamps are best suited to specimens that will be excised or otherwise removed. Allis clamps are frequently required in vaginal and abdominal surgery. Babcock clamps are atraumatic instruments useful for grasping delicate structures, such as the oviducts, utero-ovarian ligaments, and other fragile tubular structures ( Fig. 4.2A and B ). Ochsner clamps, for example, may be applied to the cervix for traction during vaginal hysterectomy or on skin scars that are going to be cut out ( Fig. 4.2C and D ).

Dissecting or hemostatic clamps include standard and long tonsil clamps ( Fig. 4.3A and B ). These are excellent for fine dissection and for clamping bleeding vessels deep within the pelvis, particularly in strategic locations. The tips of these clamps are tapered and angled. One variety, the right-angle clamp, has a 90° angle ( Fig. 4.3C ). This is the instrument of choice for isolating large arteries from underlying veins, as occurs during hypogastric artery ligation.

Hemostatic clamps may be straight or curved. Mosquito clamps and the larger Kelly clamps are most commonly used to secure bleeding vessels. In addition, the fine mosquito clamps may also be used as dissecting tools ( Fig. 4.4A and B ).

Large vascular pedicle clamps used for hysterectomy or radical hysterectomy should incorporate powerful, atraumatic jaws, a variety of curvatures, and suitable length to facilitate securing these large pedicles. These characteristics are exemplified by the Zeppelin clamps ( Fig. 4.5A to C ). Haney clamps of the straight and curved variety are the most common pedicle clamps used in the performance of vaginal hysterectomy ( Fig. 4.5D ).
