Abstract: A surgical vessel clip applier handle is provided and has a head unit capable of being flipped relative to a handle body having a front end pivotally connected to the head unit. An embedding opening is formed on the top of a barrel part of the handle body. Two slides blocks are disposed inside the barrel part at a front position and a rear position. The front part of a grip part of the handle body has a trigger having a linkage assembly disposed between the trigger and the slide blocks. The invention is capable of installing and removing conventional clamping assemblies by simply flipping the head unit; when the head unit is flipped back, the rear end of the clamping assembly will connect to the slide blocks via the embedding opening, the linkage assembly thereby drives the clamping assembly to clamp while the trigger is being pulled by a user.

Abstract: A valve mechanism for a suction instrument or an irrigation instrument includes a valve object; a first piston moveably disposed in the valve object; a second piston moveably disposed in the valve object; and a piston buckling unit pivoting on an outside of the valve object. When the first piston is pressed, the first piston moves downward, and a first buckle on the first piston is fixed on a third buckle of the piston buckling unit to open an irrigating pathway. When the second piston is pressed, the second piston moves downward, and a second buckle on the second piston is fixed on another third buckle of the piston buckling unit to open a suction pathway.
