A pair of endoscopic scissors having an actuating means at the proximal end and a pair of pivotable scissor blades at the distal end. The actuating means is adapted to be squeezed to a predetermined point when the scissor blades are fully closed, at least one of the blades being provided with a stop surface adjacent its proximal end in order to prevent the blade tips from crossing over each other in their fully closed position. The gap between the actuating means at the proximal end of the instrument enable the application of additional force between the pivotable scissor blades without causing the blades to cross-over each other.

Endoscopic scissors

An endoscopic surgical instrument which is able to be disassembled in order to facilitate cleaning of the instrument or replacement of certain components. The instrument comprises a handle portion at the proximal end of an elongated rotatable shaft, the handle portion including a pair of handles biased into a normally open position and movable between the normally open position and a closed position. Movement of the handles within the normal range serves to axially move an elongated working element situated within the hollow interior of the elongated sleeve, the proximal end of the working element shaft having a stud adapted to be received within a stud recess in one of the handles. The stud recess has a front slotted wall and an open top end. A spring means is provided in order to bias the handles during normal operation and a latch means is provided in order to disengage the spring. When the spring is disengaged, the handles may be moved beyond their normal range of motion so they may be placed into a disassembly position in which the stud on the proximal end of the working element may be pulled distally from the stud recess in order to enable the working element to be removed from the instrument.

Cleanable endoscopic surgical instrument

An automatic hemostatic clip applicator is disclosed wherein the jaws, cartridge assembly and jaw housing move together in a single direction to crimp a clip resulting in a perception of little or no motion by the jaws when the applicator is activated. Camming surfaces in the jaws are brought into contact with camming surfaces on the distal end of the stationary body of the applicator as the jaws are moved proximally.
