  • Patent number: 7494262
    Abstract: A bulb retainer device for use with bulbs such as halogen burner bulbs on vehicles subject to vibration and oscillation. The bulb has a flat burner glass press area and a receptacle is used for mounting the bulb in position to function as a light. A one piece metal sheet bulb retainer is mounted on the receptacle. The retainer has a circular drawn cup in its surface for slidably mounting the retainer on the receptacle. The retainer further has a plurality of arcuate fingers in the cup and sized to engage the bulb flat burner glass press area to restrain movement thereof. The preferred number of fingers is four and the retainer is fixedly mounted on the retainer after assembly.

  • Patent number: 5871135
    Abstract: A surgical stapler comprising at least one cam having a cam surface, an arrangement for actuating the cam for a longitudinal firing movement of the cam surface, a cartridge having a plurality of staple drive members driven by the longitudinal movement of the cam surface, and a plurality of surgical staples respectively associated with the staple drive members for being fired by the longitudinal movement of the cam surface. In one embodiment of the present invention, the staple drive members include at least a pair of alternating first and second staple drive members, the first staple drive member including a laterally spaced pair of staple driving surfaces, the second staple drive member including a single staple driving surface. The first and second staple drive members are disposed such that the staple driving surfaces thereof are arranged in laterally spaced three rows.

  • Patent number: 5735874
    Abstract: A surgical handheld instrument which is used in a minimally invasive surgical procedure such as a laparoscopic surgical procedure comprises a handle body and an elongated shaft connected to the handle body at a proximal end of the shaft. An end effector such as a pair of movable jaws are located at the distal end of the shaft. An actuation handle member is movably connected to the handle body and is operatively connected to the end effector for actuating movement of the end effector. Thus, upon movement of the handle actuation member, the end effector, such as movable jaw elements, can be opened or closed. The handle body also includes a locking tab, having a Z-shaped configuration wherein one end of the locking tab has a hole therethrough. An arcuate locking rod having a smooth, uniform surface is connected at one end to the handle actuation member and is insertable at its opposite end through the hole of the locking tab such that the arcuate locking rod is in movable contact with the locking tab.

  • Patent number: 5562702
    Abstract: A jaw assembly is provided with a pair of jaws which are closed with a flexible, tension member that is pulled by the operator of the instrument. In a preferred embodiment, one of the jaws is pivotally mounted in a slot to the other jaw. A cord, having a loop configuration, is attached to the pivoting jaw and can be pulled to pivot the jaw closed. A second cord can be provided to initially hold the proximal end of the pivoting jaw away from the other jaw until the distal ends of the jaws are closer together. In another embodiment, jaws can be closed in a parallel orientation by rotating two pulleys with threaded shafts engaged with the jaws.

  • Patent number: 5263629
    Abstract: A method and apparatus to achieve hemostasis along a staple line by utilizing a pledget material positioned adjacent at least one surface of tissue. A line of staples extends through the tissue and the pledget material. The pledget material substantially uniformly distributes pressure along the staple line and thereby causes substantial hemostasis along the tissue cut. The pledget material may also absorb blood that may escape from a partially open blood vessel.
