Abstract: The invention provides a system and method for performing less-invasive surgical procedures within a body cavity. In a preferred embodiment, the invention provides a system and method for temporarily occluding a blood vessel in an arterial graft in a thoracoscopic coronary artery bypass grafting procedure. The system comprises a clamp (2) and an introducer (1) for introducing the clamp through a percutaneous penetration into the body cavity and applying the clamp to a tissue structure such as a blood vessel. The clamp has a pair of movable jaws (65, 67) coupled to one another, each jaw having a distal portion for engaging the tissue structure and a proximal portion having a camming surface (66, 68). The introducer has a longitudinal shaft (3) with a clamp engaging means (25) slidably coupled to the distal end of the shaft for releasably holding the clamp. A handle (11) is coupled to the proximal end of the shaft. The handle can be manipulated to axially slide the shaft with respect to the clamp engaging means so that the shaft engages the camming surfaces of the clamp to open and close the distal portions of the jaws without releasing the clamp from the introducer.
Abstract translation: 本发明提供一种用于在体腔内执行较小侵入性外科手术的系统和方法。 在优选实施例中,本发明提供了一种用于在胸腔镜冠状动脉旁路移植手术中临时闭塞动脉移植物中的血管的系统和方法。 该系统包括夹具(2)和导引器(1),用于将夹具通过经皮穿透引入体腔并将夹具施加到诸如血管的组织结构。 夹具具有彼此联接的一对可动爪(65,67),每个钳口具有用于接合组织结构的远端部分和具有凸轮表面(66,68)的近端部分。 导引器具有纵向轴(3),其具有可滑动地联接到轴的远端的夹具接合装置(25),用于可释放地保持夹具。 手柄(11)联接到轴的近端。 可以操纵把手以相对于夹具接合装置轴向地滑动轴,使得轴接合夹具的凸轮表面,以打开和关闭钳口的远端部分,而不将夹具从导引器释放。
