Enlarge the opening in the vessel by inserting the probe wet with 15 per cent, glycerin. § 357. Ligatures.—While the probe is stiU in the vessel, with the fine forceps grasp the middle of a thread 30-40 cm. long and push the loop through entad of the vessel, and at a point centrad of the incision (Fig. 40). The loop may then be grasped by the fingers or forceps and drawn through, as far as desired. Instead of pushing the thi-ead through as directed above, one may put the forceps entad of the vessel first and grasp the loop. Fig. 40.—Incisions astd Prep- abation foe ligaturing ; and pull it through. Bernard, A, 263. When the thread is through as far as desired, cut the loop. The thread nearest the incision is for tying the canula in the vessel; the other is for ligaturing the ves- sel when the injection is finished. Both threads should be loosely tied in a sur- geon^ s Jcnot (Fig. 41), so that they may be quickly tightened. § 358. Introduction of the Canula.— When the threads are prepared, remove the probe from the vessel, select a canula of the proper size, that is, as large as can be put into the vessel, and make sure that it is open by blowing into it or forcing water through it with the syringe. Hav- ing wet its small end, put it into the ves- sel so that the injection will be centrad. To insert the canula, grasp one edge of the V-shaped incision with the fine for- ceps and pull it open. Now introduce the canula and push gently with a slight twisting motion. At the same time pull with an equal force in the opposite direction with the.
