  • Publication number: 20100072253
    Abstract: A surgical stapling instrument including first and second jaw members which can be pivotably connected to each other and secured in position relative to each other by a latch. The first and second jaw members can include first and second locking members which can allow the first and second jaw members to be rotated relative to one another but prevent, or at least inhibit, the first and second jaw members from being separated from one another. Such embodiments may be particularly useful in circumstances when the latch is in a partially-closed position and the first and second jaw members are being manipulated to position tissue therebetween. The first and second jaw members can be sufficiently connected together in order to prevent, or at least reduce the possibility of, the first and second jaw members from becoming detached from one another and exposing a cutting member.

  • Publication number: 20100072252
    Abstract: A surgical stapling instrument including a staple sled which can be advanced and/or retracted relative to first and second jaw members, wherein the staple sled can be configured to deploy staples from a staple cartridge in one of the first and second jaw members. In at least one embodiment, the other of the first and second jaw members can include an anvil having at least one forming surface which can be configured to deform the staples as they are deployed from the staple cartridge. In at least one form of the invention, the anvil can be movably adjustable relative to the staple cartridge in order to adjust the distance in which the staples are deformed. In various embodiments, the anvil can be adjusted by a slidable adjusting plate and/or a rotatable cam.

  • Publication number: 20100072256
    Abstract: A surgical stapling instrument including a first jaw member, a second jaw member, and a cutting member. In at least one form of the invention, the surgical stapling instrument can further include a housing which can at least partially extend over and/or around the cutting member. In various embodiments, the housing can at least partially cover the cutting member when the first and second jaw members are detached from one another, yet permit the cutting member to be moved relative to the first and second jaw members during use.

  • Publication number: 20080071295
    Abstract: A suturing apparatus for the continuous application of a suture includes a suturing head shaped and dimensioned for attachment to a distal end of a support member. The suturing head includes a track shaped and dimensioned for receiving a needle for movement about the track. A support arm includes first and second lateral arms connected by a central connecting member supporting the track, wherein the support arm includes a longitudinal axis and the track lies in a transverse plane. Angular orientation of the support arm relative to the track is achieved by positioning the transverse plane of the track at an oblique angle relative to the longitudinal axis of the support arm such that operators are provided with improved access to the surgical site. A drive assembly is coupled to the needle for controlled movement about the track.

  • Patent number: 5829662
    Abstract: A surgical stapler is provided which is insertable through an endoscopic tube to enable a surgeon to staple a hernia patch to tissue inside a body cavity. The endoscopic surgical stapler includes a staple cartridge pivotally mounted on the distal end of a support tube extending from a handle provided with an actuator mechanism for actuating a staple forming mechanism inside the staple cartridge to fasten staples to the tissue. The staple cartridge is adjustable to different angular orientations relative to the support tube. The staple actuator mechanism is operable to actuate the staple cartridge in any of the angular orientations. The support shaft is rotatable about its longitudinal axis relative to the handle to adjust the rotational orientation of the support shaft and the staple cartridge. The staple cartridge is rotatable about its longitudinal axis relative to the support shaft to adjust the rotational position of the staple cartridge relative to the support shaft.

  • Patent number: 5797536
    Abstract: A surgical instrument is provided which is insertable through an endoscopic tube to enable a surgeon to perform a surgical technique inside a body cavity. The surgical instrument includes a shaft with a pivotally mounted tip attached thereto, the shaft extending from a handle for gripping the instrument for insertion to the body cavity. The tip of the shaft is adjustable to different angular orientations relative to the support shaft and is rotatable at any angular orientation of the tip. The support shaft may be rotatable about its longitudinal axis relative to the handle, or it may be fixed with respect to the handle, in which case the handle may be rotated to rotate the shaft inside the body cavity. In one embodiment, the surgical instrument comprises an endoscopic stapling device and the tip of the instrument comprises a staple cartridge which is rotatable 360.degree. about its axes after the cartridge has been articulated with respect to the support shaft.

  • Patent number: 4627437
    Abstract: A pair of parallel, hollow needles are provided for receiving a tissue fastener of the type having at least a fastening member with a pair of legs joined by a link. Each needle has an internal passage extending from a fastening member receiving end to a discharge end. Each needle also has a slot extending along its length in communication with the passage and facing the slot of the other needle. A leg of the fastening member is placed in each needle with the fastening member link extending through the needle slots between the needles. The instrument has an anvil for being located on one side of the tissues opposite the needles. The needles are inserted through the tissues towards the anvil. Then the fastening member is pushed through the needles by a drive member so that at least a portion of the fastening member link lies against one side of the tissues and so that at least a portion of each of the fastening member legs is located and secured on the other side of the tissues.
