摘要： A snaring device for use with a percutaneous cannula positioned in a body wall and extending into a body cavity of a patient. The snaring device has an elongated, bendable member formed from a spring material and having a first bendable member end and a second bendable member end. The snaring device also has an elongated, control member having a first control member end and a second control member end. The snaring device further has an attachment flexibly connecting the first control member end and the first bendable member end, such that the attachment is insertable through the cannula while the control member is extended alongside the bendable member. A distal portion of the bendable member is configurable into a loop by simultaneously pushing on the second bendable member end and pulling on the second control member end while the distal portion is at least partially extended into the body cavity.

摘要： A multiple clip applier includes a handle portion and a pair of handles pivotably connected to opposite sides of the housing. A shaft extends from the housing and has a plurality of clips located within. A pair of opposed moveable jaws are attached to and extend from the distal end of the shaft. The jaws receive one of the clips serially when they are open and form the clip received serially when they close. A moveable forming mechanism is operatively connected to the handles by a pair of forming links. As the handles close, the forming mechanism closes the jaws to form the clip received therein, and as the handles are opened, the forming mechanism opens the jaws to receive another clip therein . A feeding mechanism is provided that has a moveable feed plate attached to the handles by a pair of feed links. The feed plate is releasably coupled to a clip pusher. As the handles are closed, the clip pusher remains stationary and uncoupled with the moving feed plate. As the handles are opened, the clip pusher is operatively coupled to the feed plate and moves to place one of the clips into the jaws.

摘要： A clip, 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.
摘要翻译：提供了一种用于结扎组织结构的夹子，夹持器和方法。施肥机具有两级致动。在第一阶段中，组织结构被定位在夹具的夹爪中。夹爪闭合并锁定到预设的力以压缩并暂时闭塞组织结构。如果令人满意地定位，则启动第二阶段，其中夹子在关闭位置通过夹具施加器的轴推进。在施放器的远端处，夹子稍微打开以捕获预压缩的组织结构，并且被放置在结构上。然后将剪辑从仪器的业务端解离。优选地，夹子包括通过连接元件彼此紧密相邻地布置成由相反方向连接的两个腿部构件。连接元件限制腿构件与相对的弹簧构件的分离，以便使腿构件彼此基本均匀地平行地偏转。

摘要： Methods and devices are provided for selectively stiffening a surgical device. In one exemplary embodiment a surgical device is provided that includes a flexible elongate insertion element and a stiffening element that extends along at least a portion of the insertion element. The insertion element can be, for example, an endoscope or a sheath configured to be disposed over an endoscope. The stiffening element can be configured to selectively stiffen when an outside force, such as a vacuum force, is applied thereto. In one embodiment the stiffening element includes a plurality of elongate members disposed in a flexible sheath. When the vacuum force is applied, the sheath can be configured to engage the elongate members to maintain the elongate members in a fixed, stiffened position, thereby stiffening at least a portion of the flexible elongate insertion element coupled thereto. Various methods for stiffening an insertion instrument, such as an endoscope, are also provided herein.

摘要： Surgical devices are disclosed herein that generally include an intracorporeal elbow joint to facilitate translational movement of an end effector while allowing a body portion of the surgical device and a trocar or working channel through which the device is inserted to be maintained in a fixed angular orientation relative to the patient. This allows a plurality of such devices to be used effectively with a single incision or access device. Such devices also generally provide end effector movement with six degrees of freedom, while maintaining a mechanical linkage between the user and the end effector and while mimicking and/or mirroring natural user movement. Various methods related to such devices are also disclosed.
