    • A pump (10) includes a motor (11) which rotates a pumping assembly (52) which includes a face plate (54) and a cylinder (56). A piston (67) reciprocates in the cylinder (56) to draw fluid into the cylinder (56) from an intake groove (78) and an intake port (76) formed in a manifold plate (73) positioned adjacent to the face plate (54), and to thereafter discharge that fluid to a discharge groove (80) and a discharge port (77) formed in the manifold plate (73). The piston (67) rides on a swash plate (49) as the face plate (54) rotates, and the extent of reciprocation of the piston (67) and therefore the amount of fluid to be dispersed on each reciprocation of the piston (67) is controlled by an adjuster wheel (40) which can be moved to allow the swash plate (49) to pivot a predetermined extent. As such, the pump (10) can dispense a known precise amount of fluid on each reciprocation of the piston (67).

    • An improved surgical instrument is provided for applying surgical fasteners, such as staples, to human tissue which is particularly suited for applying one or more rows of fasteners across a tissue lumen. The surgical instrument can be used in thoracic and abdominal surgical procedures where access to the surgical site is restricted. The surgical instrument includes an articulated fastener applying assembly mounted on a rotatable and flexible support shaft assembly to provide more convenient access to restricted surgical sites. The fastener applying assembly has a compact construction including a fixed jaw which supports a fastener cartridge and a movable jaw which supports an anvil for clamping the tissue therebetween. The fastener applying assembly includes a pin placement mechanism which is actuated by the movable jaw to control the movement of a tissue retaining pin on the fixed jaw. A dual cam mechanism is provided for driving the fasteners into the tissue clamped between the anvil and the fastener cartridge. The instrument has an actuator handle assembly with an improved actuator mechanism for closing the jaws and driving the fasteners into the tissue.

    • A compound motion cutting device for cutting a work piece includes a tubular member having first and second ends, a pair of operating members and a drive rod having first and second ends and extending longitudinally into the tubular member. One of the operating members is secured to the first end of the tubular member and the first end of the drive rod is secured to the other of the operating members. An anvil is supported proximate the second end of the tubular member and includes a surface for supporting the work piece and a slot extending through the support surface. A cutting member includes a first end pivotally attached to the second end of the drive rod and a cam slot extending laterally therethrough. A pin is supported proximate the second end of the tubular member an extends through the cam slot in the cutting member. Movement of the operating members relative to each other in one direction causes the drive rod to move the cutting member in a first longitudinal direction and the pin and cutting member cam slot cooperate to simultaneously rotate the cutting member toward the anvil and to extend at least partially into the anvil slot to cut the work piece with a combined longitudinal and rotational slicing motion.
    • 用于切割工件的复合运动切割装置包括具有第一和第二端的管状构件,一对操作构件和具有第一和第二端并纵向延伸到管状构件中的驱动杆。 操作构件中的一个固定到管状构件的第一端,并且驱动杆的第一端固定到操作构件中的另一个。 砧座靠近管状构件的第二端支撑,并且包括用于支撑工件的表面和延伸穿过支撑表面的槽。 切割构件包括枢转地附接到驱动杆的第二端的第一端和横向延伸穿过的凸轮槽。 销靠近管状构件的第二端支撑延伸穿过切割构件中的凸轮槽。 操作构件相对于一个方向的移动导致驱动杆沿着第一纵向方向移动切割构件,并且销和切割构件凸轮槽协作以同时使切割构件朝向砧座旋转并且至少部分地延伸 进入砧座槽,以组合的纵向和旋转切片运动切割工件。
