    摘要： A surgical clip applier comprising a housing, a pair of handles pivotally connected to opposite sides of the housing, and a jaw blade assembly fixedly connected to the housing. The jaw blade assembly includes a pair of jaws for receiving and deforming a clip therebetween and a clip carrier for supplying a series of clips to the jaws. A channel assembly is slidably mounted with respect to the housing and envelops the jaw blade assembly for camming the jaws closed upon closing of the handles. The clips may be fed to the jaws by a spring biased feed bar which operates upon closing of the handles, or may be urged by pusher bar which provides a biasing force to the clips to be retained by the jaws. The instrument may be used in conventional surgical procedures, or may be adapted for endoscopic and laparoscopic surgical procedures requiring the application of microsurgical clips.

    摘要翻译： 一种手术夹具，包括壳体，可枢转地连接到壳体的相对侧的一对手柄，以及固定地连接到壳体的钳口组件。 颚板组件包括一对夹爪，用于接收和变形夹子，夹子支架用于向钳口提供一系列夹子。 通道组件相对于壳体可滑动地安装并且包封钳口刀片组件，用于在手柄闭合时闭合钳口。 夹子可以通过弹簧偏置的进给杆进给到夹爪，该弹簧偏置的进给杆在关闭手柄时操作，或者可以被推杆推动，推杆对夹具保持偏压力。 该仪器可以用于常规外科手术中，或可适用于需要应用显微手术夹的内窥镜和腹腔镜外科手术。

    摘要： A surgical clip applicator comprising a housing, a pair of handles pivotally connected to opposite sides of said housing, and a jaw blade assembly fixedly connected to the housing. The jaw blade assembly includes a pair of jaws for receiving and deforming a clip therebetween and a clip carrier for supplying a series of clips to said jaws. A channel assembly is slidably mounted in the housing and envelops said jaw blade assembly. A forming cam is connected between and to said handles and said channel assembly for sliding said channel assembly in a distal direction in response to closing of said handles together to move said jaws towards each other. A feed cam bar slidably mounted in said channel assembly in overlying relation to said clip carrier, said bar having a nose at its distal end. A pusher bar sidably mounted in said channel assembly for advancing clips along said clip carrier. A first spring member connected between said cam bar and said forming cam for sliding said cam bar in a proximal direction in response to closing of said handles together and further biasing said channel assembly in a proximal direction. Second spring member biasing said pusher bar in a distal direction to push a foremost clip in said clip carrier between said jaws in response to opening of said handles from each other. A clip retainer for preventing movement of said spring biased pusher bar is also provided.
