    摘要： A tagging device for marking the location of lesions within the body prior to a surgical procedure such as excision or biopsy. The device includes an elongated tube having one end supported on a housing and a second end extending distally therefrom. An anchor is positioned within the distal end of the elongated tube and has an elongated member extending proximally therefrom. An actuation assembly including a plunger is movable within the tube to engage and push the anchor from the distal end of the tube. The anchor and the actuation assembly are positioned and configured such that the anchor is pivoted from a position parallel to the longitudinal axis of the tube to a position perpendicular to the longitudinal axis of the tube as it as being pushed from the tube.

    摘要： A self contained gas powered endoscopic surgical apparatus is provided for placing lateral lines of surgical fasteners into body tissue. The apparatus includes an anvil member and a surgical fastener cartridge member mounted to the distal end of an elongated endoscopic portion. A tubular collar of the endoscopic portion moves distally to engage the anvil member and bias the anvil member and the cartridge member into cooperative alignment, thereby clamping body tissue to be fastened between the anvil member and the cartridge member. A self contained pneumatic system is disposed in the surgical apparatus and is actuable to eject and/or form the surgical fasteners in the clamped body tissue. The apparatus further comprises a locking mechanism for preventing firing of the instrument after it has been fired a predetermined number of times. A counter for displaying the number of times the apparatus has been fired may be provided. A firing interlock is also shown which prevents accidental actuation of the firing trigger. A clamping interlock is shown which prevents approximation of the jaws when the jaws are either misaligned or improperly inserted into the instrument.

    摘要翻译： 提供一种自给式气体动力内窥镜手术装置，用于将外科紧固件的侧线放置在身体组织中。 该装置包括安装到细长内窥镜部分的远端的砧构件和手术紧固件仓构件。 内窥镜部分的管状颈部向远侧移动以接合砧座构件并将砧座构件和暗盒构件偏压成协调对准，从而将要紧固的身体组织夹紧在砧座构件和筒构件之间。 自包含气动系统设置在手术设备中并且可致动以在夹持的身体组织中弹出和/或形成外科紧固件。 该设备还包括一个锁定机构，用于防止仪器在其被点火预定次数之后发射。 可以提供用于显示设备被触发次数的计数器。 还示出了防止触发触发器的意外致动的触发互锁。 示出了夹紧互锁，其防止当钳口不对准或不适当地插入仪器时近似钳口。

    摘要： A method for percutaneous dissection of a segment of vascular tissue from a patient is provided which includes providing an elongated tubular member having a proximal end and a distal end, and blunt dissection structure positioned adjacent the distal end of the tubular member and remotely actuable from adjacent the proximal end of the tubular member. The method further provides for percutaneously accessing a first end portion of the vascular tissue segment, the blunt dissection structure is positioned adjacent the vascular tissue segment and is actuated to bluntly dissect the vascular tissue segment from surrounding body tissue.
