    • Over the years, a variety of different types of non-ultrasonically powered cutters and shaving devices for performing surgical procedures have been developed. Some of these devices employ a rotary cutting instrument and other devices employ a reciprocating cutting member. For example, shavers are widely used in arthroscopic surgery. These devices generally consist of a power supply, a handpiece, and a single-use end effector. The end effector commonly has an inner and outer tube. The inner tube rotates relative to the outer tube and will cut tissue with its sharpened edges. The inner tube can rotate continuously or oscillate. In addition, such device may employ a suction channel that travels through the interior of the inner tube. For example, U.S. Pat. No. 4,850,354 to McGurk-Burleson, et al., discloses a non-ultrasonically powered surgical cutting instrument that comprises a rotary cutter for cutting material with a shearing action. It employs an inner cutting member which is rotatable within an outer tube.
    • 多年来,已经开发了用于执行外科手术的各种不同类型的非超声波动力切割器和剃须装置。 这些设备中的一些采用旋转切割仪器,并且其它装置采用往复式切割构件。 例如,剃须刀被广泛用于关节镜手术。 这些装置通常由电源,手机和单次使用的末端执行器组成。 末端执行器通常具有内管和外管。 内管相对于外管旋转,并以其锋利的边缘切割组织。 内管可以连续旋转或摆动。 此外,这种装置可以采用穿过内管内部的抽吸通道。 例如,美国专利 McGurk-Burleson等人的No.4,850,354公开了一种非超声波动力的手术切割仪器,其包括用剪切材料切割剪切动作的旋转切割器。 它采用可在外管内旋转的内切割构件。

    • A surgical needle holder for use in open or laparoscopic surgery, that grasps a needle or a suture filament . The needle holder has a lower jaw, and an upper jaw moveable from an open to a closed position. The lower jaw has a pair of lower jaw ledge surfaces and a groove. The upper jaw has a grasping protrusion surface that can be embedded within a groove in the lower jaw, when the upper jaw is closed. When the jaws are closed on a needle, it is grasped with a three point needle contact system. The needle contact points are the two lower jaw ledges and the upper jaw grasping protrusion surface. Closure of the jaws on a curved needle "rights" the needle. When the jaws are closed on a suture filament, the upper jaw protrusion surface and the groove form a labyrinth path that effectively grasps the suture filament relative to the end effector. This enables the surgeon to apply tension to a suture to produce a tight knot or, when proximating tissue, tension a suture loop.
    • 用于开放式或腹腔镜手术的外科用针保持器,其可以抓住针或缝合线。 针架具有下颚,上颚可从打开位置移动到关闭位置。 下颚具有一对下颚凸缘表面和一个凹槽。 当上颚关闭时,上颚具有可嵌入下颌凹槽内的把持突起表面。 当针在针上关闭时,用三点针接触系统抓住。 针接点是两个下颚凸缘和上颚抓握突起表面。 将针颚上的钳口关闭,“针”。 当钳口在缝合线上闭合时,上颌突出表面和凹槽形成迷宫路径,其相对于末端执行器有效地抓住缝线。 这使得外科医生能够对缝合线施加张力以产生紧密的结,或者当接近组织时张紧缝线环。
