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： 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 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： 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.
