    摘要: An endoscopic surgical tool (10, FIG. 1 ) with a single moveable inner tip (22), and a fixed outer tip (12) pivotably interacting via an integral essentially-hourglass-form pivot extension of both walls of the outer tip and an engaging channel (24) of the inner tip(s), articulated by a link with an integral stud and also realizable as with dual moveable inner tips (22A, 22B/FIG. 6 ), pivotably interacting with respective end-to-end adjacent essentially-hourglass-form sections of a pivot that is an integral extension of the outer tip.

    摘要: A microsurgical scissors uses a rotary cutting action and biased blades that intersect in a travelling point of contact. One blade is situated on the end of a tubular shaft and a second blade is on a rod that is rotatable within the shaft. The blades are angled so their cutting edges intersect each other. To assure a precise shearing relationship, the rod is biased rearward in order to bear the cutting edge of the rod blade against the cutting edge of the shaft blade. An actuating mechanism in the handle translates linear finger motion into rotary motion of the rod. The blades cut cleanly and surely without imparting undue tissue trauma.
