The other method is the reverse of thefirst, the pin resting upon and pressing the vessel downward upon the deep-seated tissue, instead of upward against the superficial (Figs. 93 and 94).Acupressure is often employed to arrest htemorrhage from small branches of 76 OPERATIVE Fig. 96.—Bucks needle conductor. the palm of the hand and in other similarly constituted structures. Thedistance from the open end of the vessel to the point at which the pressureis applied depends on the size of the vessel—if large, within one half inch;if smaller, the distance is lessened proportionately to the size. The introduction of the pin can be facilitated by the aid of Bucks pinconductor (Fig. 9C), which when passed beneath the vessel and out through the integument at the oppo-site side will, on withdrawal,properly place the pin, pro-vided the point of the latterbe well inserted into the openend of the instrument. Asurgical needle, curved orstraight, according to situa-tion, can be passed beneath avessel and caused to effect theclosure in a similar manneras with the pin. Circumclusion, torsoclu-sion, and retrodusion arevariations in the method of pin pressure arising either from twisting orcompressing the caliber of the vessel. These methods seem to possess butone distin
