摘要： A surgical stapling instrument for performing a circular anastomosis stapling operation is provided. The surgical instrument includes a stapling head assembly mounted by a flexible support shaft to an actuator handle assembly. The support shaft is capable of bending in any radial direction relative to its centerline into a curved configuration suitable for insertion into a patient. The flexible support shaft includes a dual coil structure which is adapted to support itself in any curved configuration and to resist deflection upon insertion into the patient and actuation of the stapling head assembly. The stapling head assembly includes a driver assembly which is operable in multiple stages to separate te staple forming and tissue cutting actions to reduce the peak force required to operate the instrument. The actuator handle assembly includes a staple actuating lever and a cam follower assembly which operate in two stages with different mechanical advantages to facilitate the operation of the instrument by a surgeon. The actuator handle assembly includes a thumb wheel for opening and closing the anvil and an adjusting knob for adjusting the anvil gap. A control lever is provided for pivoting the stapling head assembly relative to the flexible support shaft.

摘要： A system is described for sensing the relative angular orientation of two relatively movable joint segments of a living body joined together at a joint. The system comprises at least two links coupled together about a pivot axis so that the links are pivotable relative to one another about the axis so as to define a variable mechanical angle between the links about the axis. The two links are secured respectively to the joint segments so that the links pivot about the pivot axis when the joint segments pivot about said joint. A Hall effect sensor is used to accurate sense the mechanical angle. The mechanical angle sensed by the sensor is then correlated with the actual angle made by the joint segments. The arrangement is used with each finger and thumb joint of the hand to provide data representative of finger and thumb orientations of a hand.

摘要： A liquid removal system having an interface device and a vacuum source are described. The interface device has a porous membrane with an entrance zone on one side. The vacuum source maintains a vacuum on the side of the membrane opposite the entrance zone when the membrane is wetted. Liquid which contacts the wetted porous membrane is removed from the interface device by the vacuum source.

摘要： A surgical stapling instrument for performing a circular anastomosis stapling operation is provided. The surgical instrument includes a stapling head assembly mounted by a curved shaft to an actuator handle assembly and incorporates an improved actuator mechanism for transmitting the required operating forces and movements from the actuator handle assembly through the curved shaft to an anvil and staple driver of the stapling head assembly. The stapling head assembly includes a longitudinally movable trocar detachably secured by one or more retainer clips on a hollow shaft of the anvil. When the trocar is retracted, the anvil shaft slides into a central support tube which aligns the anvil axially and circumferentially with a staple holder on the stapling head assembly. The retainer clips are locked against the trocar by the support tube and transmit tension from the trocar to the anvil with no tension load on the anvil shaft. The actuator mechanism permits adjustment of the anvil gap to produce a desired staple height and precludes actuation of the staple head assembly if the anvil gap is set outside of a predetermined range. Also, the actuator mechanism is adapted to both advance and retract the staple driver relative to the staple holder in the stapling head assembly. Further, an improved arrangement for attaching the support shaft to the stapling head assembly and to the actuator handle assembly is provided.
摘要翻译：提供了一种用于执行圆形吻合缝合操作的外科缝合器械。手术器械包括一个装订头组件，该装订头组件通过弯曲的轴安装到致动器手柄组件上并且包括改进的致动器机构，用于将所需的操作力和从致动器手柄组件通过弯曲轴的运动传递到钉子的砧座和缝钉驱动器头组件。缝合头组件包括可由一个或多个保持夹固定在砧座的空心轴上的可纵向移动的套管针。当套管针缩回时，砧座轴滑入中心支撑管，该中心支撑管使砧座轴向和周向与钉在钉头组件上的缝钉保持架对准。保持夹通过支撑管锁定在套针针上，并将张力从套管针传递到砧座，在砧座轴上没有张力负载。致动器机构允许调整砧座间隙以产生期望的钉高度，并且如果砧座间隙设定在预定范围之外，则阻止钉头组件的致动。此外，致动器机构适于相对于缝合头组件中的缝钉保持器使订书钉驱动器前进和缩回。此外，提供了一种用于将支撑轴附接到装订头组件和致动器手柄组件的改进的布置。

摘要： The liquid removal system of the present invention is designed to permit efficient liquid removal as needed through the use of an interface device. The interface device is provided with a membrane which has and is capable of maintaining a vacuum on one side so that when liquid contacts the opposite side of the membrane the liquid passes through the membrane and is removed from the interface device by a maintained vacuum to a receptacle for disposal. When used as a female external catheter system, the present invention is designed to remove urine from incontinent female hospital and nursing home patients and even patients under home care.
