摘要： A clip applier and method for ligating a tissue structure is provided. The applier has a two stage actuation. In the first stage, a tissue structure is positioned into the jaws of the clip applier The jaws close and lock to a preset force to compress and temporarily occlude the tissue structure. If satisfactorily positioned, the second stage is initiated in which a clip is advanced through the shaft of the clip applier in a closed position. At the distal end of the clip applier, the clip is opened slightly to capture the pre-compressed tissue structure, and is placed over the structure. The clip is then dissociated from the business end of the instrument. Preferably the clip comprises two leg members disposed in close proximity to one another joined from opposing directions by a connecting element. The connecting element restricts separation of the leg members with opposing spring members so as to provide substantially uniform parallel deflection of the leg members from each other.

摘要： A surgical clip applying apparatus comprises an actuator device, a ratchet mechanism, a locking mechanism, and a clip driving device. The actuator device comprises an interior and a cam mechanism disposed therein. The cam mechanism comprises an axial cam surface. The locking mechanism is movable by the actuator device within the interior in a distal direction and in a proximal direction. While moving in the distal direction, the locking mechanism contacts the axial cam surface, thereby causing the locking mechanism to engage the ratchet mechanism to limit movement of the locking mechanism in the proximal direction. Continued movement of the locking mechanism in the distal direction causes the locking mechanism to move off the axial cam surface, thereby enabling the locking mechanism to bypass the ratchet mechanism during a return stroke.

摘要： A surgical clip applying apparatus comprises an actuator device, a pair of opposing jaws, and an elongate assembly interposed therebetween. A clip driving device disposed in the elongate assembly is actuated by the actuator device to sequentially drive clips through the elongate assembly into engagement with the jaws. A clip control element is disposed in the elongate assembly at a distal end thereof. The clip control element comprises first, second, and third clip control surfaces. The first clip control surface contacts a first end of a clip to cause the clip to rotate about the first end. The second and third clip control surfaces receive a second end of the clip therebetween prior to the clip being driven into engagement with the jaws. A chicane is provided near the distal end of the elongate assembly to provide a diverting path for clips so that as one clip is being rotated, the next clip can be further advanced without contacting the rotating clip.

摘要： A surgical stapling instrument which has an elongated staple cartridge and anvil is disclosed. The anvil is movable relative to the cartridge from rearward to forward positions for insertion of tissue between these two components and clamping the tissue, respectively. A pair of spaced-apart ribs protrude from the anvil, and when the anvil is moved from its rearward to forward positions, these ribs are received into and slide within a groove embedded on the surface of the cartridge. In this manner, misalignment of the anvil and cartridge when tissue is being clamped is prevented or appreciably reduced, therefore reducing the chances of misforming the staples when the instrument is fired. The alignment features also act as tissue abutment surfaces to prevent the migration of tissue into a region where tissue is transected but not stapled.

摘要： 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. Separate actuator mechanisms are provided on the handle to control the pivotal movement of the staple cartridge, the rotation of the support shaft, and the rotation of the staple cartridge relative to the support shaft.

摘要： A surgical stapling instrument for performing a circular anastomosis stapling operation is provided. The surgical instrument includes a stapling head assembly mounted by a curved shaft to an actuator handle assembly and incorporates an improved actuator mechanism for transmitting the required operating forces and movements from the actuator handle assembly through the curved shaft to an anvil and staple driver of the stapling head assembly. The stapling head assembly includes a longitudinally movable trocar detachably secured by one or more retainer clips on a hollow shaft of the anvil. When the trocar is retracted, the anvil shaft slides into a central support tube which aligns the anvil axially and circumferentially with a staple holder on the stapling head assembly. The retainer clips are locked against the trocar by the support tube and transmit tension from the trocar to the anvil with no tension load on the anvil shaft. The actuator mechanism permits adjustment of the anvil gap to produce a desired staple height and precludes actuation of the staple head assembly if the anvil gap is set outside of a predetermined range. Also, the actuator mechanism is adapted to both advance and retract the staple driver relative to the staple holder in the stapling head assembly. Further, an improved arrangement for attaching the support shaft to the stapling head assembly and to the actuator handle assembly is provided.
摘要翻译：提供了一种用于执行圆形吻合缝合操作的外科缝合器械。手术器械包括一个装订头组件，该装订头组件通过弯曲的轴安装到致动器手柄组件上并且包括改进的致动器机构，用于将所需的操作力和从致动器手柄组件通过弯曲轴的运动传递到钉子的砧座和缝钉驱动器头组件。缝合头组件包括可由一个或多个保持夹固定在砧座的空心轴上的可纵向移动的套管针。当套管针缩回时，砧座轴滑入中心支撑管，该中心支撑管使砧座轴向和周向与钉在钉头组件上的缝钉保持架对准。保持夹通过支撑管锁定在套针针上，并将张力从套管针传递到砧座，在砧座轴上没有张力负载。致动器机构允许调整砧座间隙以产生期望的钉高度，并且如果砧座间隙设定在预定范围之外，则阻止钉头组件的致动。此外，致动器机构适于相对于缝合头组件中的缝钉保持器使订书钉驱动器前进和缩回。此外，提供了一种用于将支撑轴附接到装订头组件和致动器手柄组件的改进的布置。
