    • An endoscopic stapler includes a stapling head which is removably locatable on the distal end of an endoscope. The stapling head includes a stationary part which houses a removable staple cartridge and a movable part which includes an anvil for receiving and bending the ends of staples fired from the stationary part. The staple cartridge preferably houses two semi-circular rows of staples which are staggered relative to each other. The movable part is coupled to the stationary part by a threaded shaft which engages a worm gear in the stationary part and a first rotatable control wire is coupled to the worm gear. A substantially semi-circular firing cam is located proximal of the staple cartridge in the stationary part. The firing cam has an interior splined surface which is engaged by a spline gear coupled to a second rotatable control wire. In one embodiment, a knife is coupled to the firing cam so that tissue is cut subsequent to stapling. In another embodiment, laser-optical paths are provided for cutting tissue after stapling. The proximal end of the stapling head is coupled to a sleeve having lumen for the control wires and a lumen for a standard endoscope. In another embodiment, a modified endoscope is provided with lumena for the control cables. The modified endoscope is removably attached to the stapling head by either a screw connection or a snap connection.
    • 内窥镜吻合器包括可拆卸地定位在内窥镜的远端上的吻合头。 装订头包括容纳可拆卸钉仓的固定部分和可移动部件,该可动部件包括用于接收和弯曲从固定部分发射的钉的端部的砧座。 钉仓优选地容纳相对于彼此交错的两个半圆形的订书钉行。 可移动部分通过与固定部分中的蜗轮啮合的螺纹轴联接到固定部分,并且第一可旋转控制线联接到蜗轮。 基本上半圆形的点火凸轮位于固定部分中的钉仓的近侧。 射击凸轮具有内部花键表面,该内部花键表面由联接到第二可旋转控制线的花键齿轮接合。 在一个实施例中,刀被联接到击发凸轮,使得在缝合之后组织被切割。 在另一个实施例中,提供激光光路以便在缝合之后切割组织。 吻合头的近端联接到具有用于控制线的内腔和用于标准内窥镜的内腔的套管。 在另一个实施例中,改进的内窥镜设置有用于控制电缆的灯罩。 改进的内窥镜通过螺钉连接或卡扣连接可拆卸地附接到装订头。
