Bronchoscopic And Esophagoscopic Grasping ForcepsCategory: INSTRUMENTARIUM Source: A Manual Of Peroral Endoscopy And Laryngeal Surgery are of the tubular type, that is, a stylet carrying the jaws works in a slender tube so that traction on the stylet draws the V of the open jaws into the lumen of the tube, thus causing the blades to approximate. They are very delicate and light, yet have great grasping power and will sustain any degree of traction that it is safe to exert. They permit of the delicacy of touch of a violin bow. The two types of jaws most frequently used, are those with the forward-grasping blades shown in Fig. 18, and those having side-grasping blades shown in Fig. 19. The side-curved forceps are perhaps the most generally useful of all the endoscopic forceps; the side projection of the jaws makes them readily visible during their closure on an object; their broader grasp is also an advantage., The projection of the blades in the side-curved grasping forceps should always be directed toward the left. If it is desired that they open in another direction this should be accomplished by turning the handle and not by adjusting the blade itself. If this rule be followed it will always be possible to tell by the position of the handle exactly where the blades are situated; whereas, if the jaws themselves are turned, confusion is sure to result. The forward-grasping forceps are always so adjusted that the jaws open in an up-and-down direction. On rare occasions it may be deemed desirable to turn the stylet of either forceps in some other direction relative to the handle. [FIG. 18.--The author's forward grasping tube forceps. The handle mechanism is so simple and delicate that the most exquisite delicacy of touch is possible. Two locknuts and a thumbscrew take up all lost motion yet afford perfect adjustability and easy separation for cleansing. At A is shown a small clip for keeping the jaws together to prevent injurious bending in the sterilizer, or carrying case. At the left is shown a handle-clamp for locking the forceps on a foreign body in the solution of certain rarely encountered mechanical problems. The jaws are serrated and cupped.] [FIG. 19.--Jaws of the author's side-curved endoscopic forceps. These work as shown in the preceding illustration, each forceps having its own handle and tube. Originally the end of the cannula and stylet were squared to prevent rotation of the jaws in the cannula. This was found to be unnecessary with properly shaped jaws, which wedge tightly.] Next: Rotation Forceps Previous: Forceps
