    摘要： A novel surgical retractor is provided including a handle assembly, a housing and a collapsible retractor assembly connected to a distal end of the housing. The handle assembly includes a stationary handle in cooperation with an actuating structure for manipulating the collapsible retractor assembly through the housing.The handle assembly may be configured in a variety of forms including palm grips, pistol grips, axial grips, ring grips, etc. The housing includes a tubular structure having an inner tube axially disposed within an outer tube. The outer tube is fixed in the stationary handle with the inner tube passing through the outer tube and connected to the actuating structure. Where desired, either the outer or inner tube may be rotatably attached to the stationary handle. The retractor assembly is attached to the distal end of the housing and includes a reciprocal yoke assembly interconnected with a plurality of collapsible interleaved retractor blades. One element of the yoke assembly is typically maintained stationary while the other is allowed to reciprocate axially to deploy the interleaved retractor blades into a fan configuration.

    摘要翻译： 提供了一种新颖的外科牵开器，其包括手柄组件，壳体和连接到壳体的远端的可收缩牵开器组件。 手柄组件包括与用于操纵通过壳体的可收缩牵缩器组件的致动结构配合的固定手柄。 手柄组件可以被配置成各种形式，包括手掌握柄，手枪把手，轴向夹具，环把手等。壳体包括管状结构，其具有轴向设置在外管内的内管。 外管固定在固定手柄中，内管通过外管并连接到致动结构。 在需要的情况下，外管或内管可以可旋转地附接到固定手柄。 牵开器组件附接到壳体的远端，并且包括与多个可收缩交错的牵开器叶片互连的互动轭组件。 轭组件的一个元件通常保持静止，而另一个元件允许轴向往复运动，以将交错的牵开器叶片部署成风扇构造。

    摘要： A surgical stapling apparatus comprising an anvil jaw pivotally connected to a first handle for movement from an open position to a closed position to clamp body tissue, staple advancing means for advancing an individual staple into contact with the anvil jaw for deformation of the staple legs and means for closing the anvil and for actuating the staple advancing means in a three phase movement of the handles. In the first movement of the handle the anvil jaw pivots to a closed position; in a second subsequent movement of the handles the anvil jaw remains stationary and the staple advancing means is not yet actuated; and in a third movement of the handle the staple advancing means is actuated. This second movement constitutes a dwell period of the apparatus.

    摘要： A surgical stapling apparatus having first and second handle members pivotably mounted to one another for movement from an open position to a closed position to clamp body tissue between the distal jaws. After the body tissue is clamped, a trigger mechanism is activated to advance a staple pusher to force a staple through the tissue and into contact with an anvil to deform the staple legs. An actuating lever may be interposed between the trigger mechanism and the staple pusher.
