Abstract: A disposable inflatable tourniquet cuff which may include an inflatable bladder having inner and outer walls which, in order to reduce cost and complexity, may be of the same size and made from the same material. A stiffener may be located within the bladder's inflatable fluid space, to eliminate the need for any separate parts to properly locate or hold the stiffener. The walls may have exterior, velcro-type soft, fuzzy loops or filaments; and be secured together with welds having a width selected to prevent the longitudinal sides of the cuff from spontaneously rolling up. The soft, fuzzy inner wall may serve as the patient contacting part of the cuff, thereby eliminating the need for a separate soft, fuzzy inner cover to protect the patient; and may serve to engage the hook-type velcro surface on other parts of the cuff, to hold them in the desired position.

Abstract: An endoscopic or laparoscopic surgical instrument is disclosed having a handle assembly including a barrel portion, stationary handle and a pivoting handle. A body assembly includes a pair of coaxial members attached at one end to the handle assembly, and an inner rod member slidable within an outer tube member in response to movement of the pivoting handle of the handle assembly. The body assembly terminates at an end remote from the handle assembly in a reciprocatingly movable tool mechanism. A first toothed ratchet mechanism is associated with the pivoting handle, and a second toothed mating ratchet mechanism is operatively associated with the first toothed ratchet mechanism for selectively locking the first toothed ratchet mechanism and the pivoting handle in one of a plurality of selectable positions to thereby position the inner rod member and the movable tool mechanism in predetermined selectable positions.
