摘要： A clip applier for applying a surgical clip in a patient comprising a disposable cartridge and a reusable actuating mechanism. The cartridge includes an elongate tube having a proximal end and a distal end, a pair of opposing jaw members extending outwardly from the distal end of the elongate tube, and a one-way ratchet mechanism providing a full actuating stroke. The actuating mechanism is coupled to the proximal end of the elongate tube to move the jaw members between an open position and a closed position. The ratchet mechanism may be formed from injection molded plastic. The cartridge further comprises a push member for advancing the clip into the jaw members, a biasing spring for maintaining the push member against the clip, and a drive coupling operatively connected to a sliding ratchet pawl for engaging with mating teeth formed on an inner surface of the elongate tube, wherein the ratchet pawl includes a cantilever arm that engages with the mating teeth, and wherein the drive coupling provides a central connection of the ratchet pawl allowing pivoting and improved seating of the mating teeth. A method of applying a surgical clip to an object in a patient using the clip applier of the invention includes the steps of positioning the clip applier within the patient such that the jaw members are adjacent to the object to be clipped, closing the jaw members and the clip over the object, and removing the clip applier from the patient. The method may further comprise the steps of orienting the clip applier such that the jaw members pass over the object, manipulating the jaw members to move the object to a compressed state within the jaw members, advancing the clip over the object to maintain the object in the compressed state, and retracting a feeder to allow the next clip to be fed into the jaw members.
摘要翻译：一种用于在包括一次性药筒和可重复使用的致动机构的患者中施加手术夹子的施夹器。药筒包括具有近端和远端的细长管，从细长管的远端向外延伸的一对相对的钳口构件，以及提供完全致动行程的单向棘轮机构。致动机构联接到细长管的近端，以使夹爪构件在打开位置和关闭位置之间移动。棘轮机构可以由注模塑料形成。墨盒还包括用于将夹子推进到夹爪构件中的推动构件，用于将推动构件保持抵靠夹子的偏置弹簧，以及可操作地连接到滑动棘爪的驱动联接器，用于与形成在夹子的内表面上的配合齿接合所述细长管，其中所述棘爪包括与所述配合齿接合的悬臂，并且其中所述驱动联接器提供所述棘爪的中心连接，从而允许所述配合齿的枢转和改进的安置。使用本发明的施放器将外科夹子应用于患者物体的方法包括以下步骤：将夹具施放器定位在患者体内，使得钳口构件邻近要夹紧的物体，闭合钳口构件和夹在物体上，并从患者身上移除夹子施放器。该方法还可以包括以下步骤：使夹持器定向成使得钳口构件越过物体，操纵钳口构件以将物体移动到夹钳构件内的压缩状态，将夹子推进到物体上以将物体保持在压缩状态，并且缩回供给器以允许下一个夹子被馈送到钳口构件中。
