    _ while the one for the ablation of tumors is exceptionally heavy and equipped with a strong chain because of Ae creat strain to which it is usually submitted. Emasculators are also made in different styles for differ- ent purposes. The male emasculator is short and stout, while that for the female is long and slender. Aside from these two special instruments ecrasement is sometimes effected with artery forcep or even by the thumb nails. WZ a ANN ZX NNN Fig. 27—Hausmann & Dun’s New Emasculator. TECHNIQUE.—The technique of ecrasement is com- paratively simple. The organ or part is first exposed, and then the crushing instrument is made to crush it off at the de- sired point. The bruising to which the vessels and the tis- sues supporting them are submitted will generally prevent bleeding, and thus obviate ligation, cauterization, compres- sion or any of the other expedients necessary to prevent the inevitable hemorrhage that follows the division of blood ves- sels by other methods. Sometimes it is thought advisable to crush the vessels at two points some little distance apart. The crushing instru- ment is first made to crush the structure without entirely dividing it, at a point one inch or less above the seat of abla- tion, and then dropped lower down to effect a complete divis- ion. This method assures more perfect haemostasis, in ves- sels deprived of their normal hemostatic propensities from disease of their walls or the tissues conveying them.
