    摘要： A surgical stapler instrument is provided for applying lateral lines of staples to tissue while cutting the tissue between those staple lines. The instrument includes a handle portion, an implement portion, a reciprocating section, a drive member and a movable actuator. The implement portion includes a staple cartridge and an anvil. The reciprocating section is adapted to move back and forth along an axis of the implement portion. The movable actuator is associated with the handle portion and is engaged with the drive member such that motion of the actuator causes the drive member to move back sand forth between first and second drive positions separated by a first distance. A multiplier is further provided and is associated with the reciprocating section and the drive member for causing the reciprocating section to move back and forth between first and second reciprocating positions in response to movement of the drive member. The reciprocating section includes a work portion which, when moved distally, effects the firing of staples in the staple cartridge toward the anvil. The work portion is also provided with a reciprocating knife. The first and second reciprocating positions are separated by a second distance which differs from the first distance.

    摘要翻译： 提供了一种外科缝合器器械，用于在切割这些缝合线之间的组织的同时将组织的侧线施加到组织。 仪器包括手柄部分，工具部分，往复运动部分，驱动部件和可移动致动器。 工具部分包括钉仓和砧座。 往复运动部分适于沿着工具部分的轴线前后移动。 可移动致动器与手柄部分相关联并且与驱动构件接合，使得致动器的运动导致驱动构件在分开第一距离的第一和第二驱动位置之间向后移动砂。 进一步提供乘法器，并且与往复运动部分和驱动部件相关联，用于使往复运动部分响应于驱动部件的运动在第一和第二往复运动位置之间往复运动。 往复运动部分包括工作部分，当远端移动时，使订书钉钉钉上的订书钉朝向砧座的作用。 工作部分还设置有往复刀。 第一和第二往复运动位置与第一距离不同的第二距离分开。

    摘要： A system comprising a microprocessor-controlled transfer device and a separate catheter for intraluminal treatment of a selected site in a body of a patient by at least one treating element advanced from a removable treating element cartridge received in the transfer device into a lumen of the separate catheter by means of pressurized fluid controlled by a fluid control switch moveable between send and return positions. A safety interlock is provided for preventing both (1) the disassembly of the system unless the treating element resides in the treating element cartridge and (2) the actuation of the fluid control switch unless the system is assembled. The safety interlock comprises a first lock moveable from a first position to a second position only if both the catheter and the treating element cartridge are secured to the transfer device. The first lock blocks the movement of the fluid control switch to the send position when in its first position and prevents disassembly of either the catheter or the treating element cartridge from the transfer device when in its second position. The fluid control switch further locks the first lock into its second position when the fluid control switch is in the send position. A system is also provided for detecting whether the treating element resides at a targeted location along the lumen of the transfer device. The detection system comprises a pressure transducer that is in fluid communication with the lumen of the transfer device so as to be capable of measuring the fluid pressure at the targeted location of the lumen. Circuitry is provided for comparing the measured presssure to a reference pressure corresponding to the pressure at the targeted location when the treating elements are stored at the targeted location under fluid pressure. A signal generator provides a signal when the measured pressure differs from the reference pressure by more than a predetermined amount. The signal may activate an optical signal and/or a mechanical interlock, the latter preventing separation of the catheter from the transfer device and preventing closure of the gate when activated by a signal from the signal generator corresponding to the pressure encountered when the treating element does not reside at the targeted location.
