URGEONS and anatomic dissectors find the process of obtaining a cIean dissection fieId tedious and time-consuming. A new surgica1 dissecting thumb forceps has been
This may be done without changing the position of the forceps in the hand. The bIade and guard have been designed so as not to interfere with the use of the instrument as a thumb

forceps. The blade may be sharpened as necessary. MedicaI Iiterature describes many different types of forceps. PearIman and Leshin,’ and Atkinson2 designed instruments which utiIize the principIe of cutting edges on the tips of peritonsiIIar abscess scissors-forceps. The adding of a knife bIade to thumb forceps provides the foIIowing advantages: (I) It aids in stripping and cIeaning fascia from the Iarger vesseIs. (2) It is useful in separating muscIe and fascia1 pIanes. (3) It decreases the handIing of various instruments. (4) It may be used to cut smaI1 vesseIs or nerves. It is believed that this instrument offers a means of conserving time both for surgeons and anatomic dissectors.

devised to shorten this process by combining a cutting blade with the thumb forceps. The surgical dissecting forceps consists of a thorn or hook-shaped cutting bIade attached to the outer surface of one prong of a thumb forceps. (Fig. I.) This bIade is just proxima1 to the tip of the forceps. The bIade is sharpened on its point and upper concave edge. The size, shape, angIe and Iocation of this bIade may be varied to meet specific needs. A guard is provided to cover the bIade when not in use. Light digita pressure releases the guard so that it may be moved readiIy from a guarded to an unguarded position or vice versa. (Fig. 2.) * From the Department
