    • 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.
    • 提供了一种用于结扎组织结构的施夹器和方法。 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。

    • An endoscopic clip applying system as described which contains a venting system and a clip applying support system which prevents closure of the mechanism before firing. The applier's jaws are spaced apart no further than the width of the applier shaft, even when holding a clip. Also, the system ensures proper loading of the clips and prevents them from falling out during loading. Further, the system describes an easily manufacturable, positively opening system which has minimized size requirements. Furthermore, a lock-out mechanism is provided so that the mechanism may not be inadvertently fired. The shaft resists excessive torque as well as holds the clip in place during firing. There are provisions for sealant and non back-up of the clips, as well as features which make the clip properly placed for closure. In an alternate embodiment, the clip applier shaft rotates about its handle mechanism.
    • 如上所述的内窥镜夹子施加系统,其包含通气系统和施加支撑系统的夹子,其防止在开火之前关闭机构。 即使握住夹子,施压器的钳口也不会间隔开施加器轴的宽度。 此外,系统确保夹子的正确装载,并防止它们在装载过程中脱落。 此外,该系统描述了一种容易制造的,正面打开的系统,其具有最小化的尺寸要求。 此外,提供了一种锁定机构,使得该机构可能不会被无意地点燃。 轴可以防止过大的转矩,也可以在点火期间将夹子保持在适当位置。 夹具的密封剂和非支撑件的设置以及使夹子适当地放置以封闭的特征。 在替代实施例中,施夹器轴绕其手柄机构旋转。

    • 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.
    • 手术夹施加装置包括致动器装置,棘轮机构,锁定机构和夹子驱动装置。 致动器装置包括设置在其中的内部和凸轮机构。 凸轮机构包括轴向凸轮表面。 锁定机构可以通过致动器装置在内部的远侧方向和近端方向上移动。 当沿远端方向移动时,锁定机构接触轴向凸轮表面,从而使锁定机构接合棘轮机构以限制锁定机构在近端方向上的移动。 锁定机构在远端方向的继续移动导致锁定机构离开轴向凸轮表面,从而使得锁定机构能够在返回行程期间绕过棘轮机构。

    • 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.
