摘要： A pneumatic fastener driving tool in which a piston-driver assembly is moved in opposed working and return strokes within a cylinder. Vent passage means of a predetermined area are provided adjacent the lower end of the cylinder to permit greatly increased velocity on the working stroke. Valve means may be provided for the vent passage to enable the use of air under pressure to drive the piston in a return stroke.The cylinder may be defined by an axially movable sleeve, which cooperates with sealing means to provide one or more valving functions.

摘要： A surgical staple for use in suturing the skin or fascia of a patient. The surgical staple has an elongated, substantially horizontal crown portion terminating in downwardly depending leg portions having points formed at their free ends. The staple, together with a plurality of identical surgical staples, is adapted to straddle and to be fed along a guide means of a surgical stapling instrument to the anvil thereof. The crown of the surgical staple is formed about the anvil by the surgical stapling instrument former which bends end portions of the surgical staple crown downwardly so that the staple leg portions are substantially coaxial with their points approaching each other. The surgical staple has a first pair of diametrically opposed flats extending respectively along the front and rear of the crown and leg portions. The surgical staple has a second pair of diametrically opposed flats, disposed at 90.degree. to the first pair of flats. One flat of the second pair extends along the upper surface of the staple crown portion and the outsides of the staple leg portions and the other flat of the second pair extends along the underside of the crown portion and along the insides of the leg portions. The flats of the first pair, cooperating with similar flats on adjacent surgical staples, assure proper feeding of the surgical staple along the surgical instrument guide means. The flats of the second pair, cooperating with the surgical stapling instrument former and anvil, prevent undesirable rotation of the staple crown portion during forming and implanting of the surgical staple.
摘要翻译：用于缝合患者皮肤或筋膜的外科手术钉。手术缝合钉具有细长的基本水平的冠部，其终止于向下悬垂的腿部，其具有在其自由端形成的点。缝钉与多个相同的外科缝合钉一起适于跨越并沿外科缝合器械的引导装置进给到其砧座。外科缝合钉的冠部通过外科缝合器械成形器围绕砧座形成，该外科缝合器械成形器向下弯曲外科缝钉冠的端部，使得钉腿部分与其彼此接近的点基本上同轴。外科缝合钉具有分别沿冠部和腿部的前后延伸的第一对直径相对的平面。手术缝合钉具有第二对直径相对的平面，与第一对平面成90度设置。第二对的一个平面沿着缝钉冠部的上表面延伸，并且钉脚部分的外侧和第二对的另一个平面沿着冠部的下侧并沿着腿部的内侧延伸。第一对的平面与相邻手术缝钉上的类似平面配合，确保沿着手术器械引导装置适当地进给外科缝合钉。与外科缝合器械成形器和砧座配合的第二对的平面在防止手术钉的成形和植入过程中防止了针头冠部的不期望的旋转。

摘要： A disposable surgical stapling instrument for the joining together of tubular body organs such as the organs of the alimentary canal. The instrument comprises an elongated body having a tubular housing portion and a coaxial cylindrical handle portion. The tubular housing portion supports at its free end a coaxial cylindrical casing containing at least one annular array of surgical staples. An adjusting rod is coaxially and non-rotatively mounted within the instrument body and has a first end extending beyond the staple-containing casing. An anvil, of improved configuration for easier removal from the anastomotic site, is removably mounted by means of an anvil nut on the first end of the adjusting rod facing the staple-containing casing. By means of an adjustment knob at the free end of the instrument body handle portion, the anvil and the adjusting rod are shiftable axially of the instrument body between a position wherein the anvil is adjacent the staple-containing casing and a position wherein the anvil is spaced from the staple-containing casing. The anvil has a plurality of anvil pockets formed therein to clinch the staples over a range of distances between the anvil and the staple casing constituting a working gap. The adjustment rod has a second end mounting an indicator cooperating with the adjustment knob to give both visual and tactile indications that the anvil is spaced from the staple casing within the operating gap. A ring scale is mounted on the adjusting knob enabling accurate setting of the distance between the anvil and the staple casing, within the working gap, according to the thickness of the tissue of the tubular body organs being joined. The instrument is also provided with a lever actuated staple driver and scalpel assembly and a slide safety lockout to prevent undesired actuation of the lever.

摘要： A disposable ligator for applying clamping clips to veins, arteries and blood vessels. The ligator comprises a first handle terminating at its forward end in a first jaw and a second jaw and a second handle, both pivotally mounted on the first handle near the forward end thereof. The handles are shiftable between open and closed positions and shift the jaws between open and closed clip-clamping positions. A clip tube containing a plurality of clips and a spring biased feeder shoe to constantly urge the clips forwardly therein is mounted in the first handle. A pusher is mounted in the first handle parallel to the clip tube in a pusher track which extends to the forward ends of the jaws. The pusher is shiftable by the first and second handles between a retracted position when the handles are closed and an extended position to locate a clip in the pusher track at the forward ends of the jaws when the handles are open. The first handle provides a ramp structure leading to the pusher track at the forward end of the clip tube which is covered by the pusher when in its extended position and exposed by the pusher when in its retracted position, thus enabling the forwardmost clip to be transferred to the pusher track in front of the pusher due to the forward urging of the clips in the clip tube, and without the necessity of moving transfer parts.

摘要： A tissue thickness measuring instrument for surgical purposes comprising a pair of opposed tissue engaging jaws. Manually graspable actuating means operatively connected to the jaws for shifting the jaws away from each other. A resilient means urges the jaws toward each other with a substantially constant predetermined force over a predetermined working range of separation distance between the jaws. At least one scale with cooperating indicator is provided in association with the jaw actuating means giving a direct reading of the thickness of the tissue being measured. The instrument may be provided with another scale by which the diameter of tubular body elements in the flaccid state can be determined.

摘要： A backup washer for the cylindrical scalpel of an intraluminal surgical stapling instrument of the type used to join tubular body organs. The washer comprises an annular member of semi-rigid material having an annular groove formed therein extending from the distal surface of the washer inwardly toward the proximal surface of the washer facing the scalpel. As a result, the washer comprises two spaced annular walls joined at their proximal ends by a thin web providing a backup surface for the scalpel. When the scalpel is advanced by the surgical stapling instrument it will abut and cut through the thin web of the backup washer. When the scalpel cuts through the backup washer web the force required to further advance the scalpel abruptly and noticeably diminishes giving the surgeon clear tactile indication that the surgical staples have been implanted and clinched in the tissue of the tubular body organs being joined and that the scalpel has completely severed the excess tissue.

摘要： A surgical stapling instrument suitable for performing a gastrointestinal anastomosis is provided. The stapling instrument incorporates an improved staple actuator mechanism operable by separate control buttons to accomplish its stapling and cutting actions in two stages. The two stage operation of the stapling instrument reduces the maximum force required to operate the instrument. The improved actuator mechanism permits selection of different staple heights to be produced by the same instrument. In addition, the actuator mechanism is designed to stabilize the upper and lower jaw members by providing longitudinal and lateral support along substantially the entire length of the operative portions of the jaw members. Preferably, the actuator mechanism comprises an elongated, I-beam structure slidably mounted for longitudinal movement relative to the jaw members. The I-beam assembly includes upper and lower flanges which provide both longitudinal and lateral support along substantially the entire length of the anvil and staple cartridge carrying portions of the jaw members. A sleeve slidably mounted on one of the I-beam flanges allows the spacing of the jaw members to be adjusted to produce one of two predetermined closed staple heights.
