    • The present disclosure relates to a sheath system for enabling access through an opening in the body of a patient is provided. The sheath system includes a dilation assembly having a radially expandable tubular sheath defining a lumen having a first cross-sectional area when in a non-expanded condition, and a handle assembly operatively coupled to a proximal end of tubular sheath, the handle assembly defining an aperture formed therein, and a first thread defined on the handle in the aperture thereof. The sheath system further includes an expansion assembly including a tubular member defining a lumen having a second cross-sectional area which is larger than the first cross-sectional area of the tubular sheath of the dilation assembly and having an outer surface defining a second thread, the second thread being arranged for engaging the first thread.

    • A suture tester for evaluating fray resistance of surgical sutures. The suture tester comprises a reciprocating drive member, first, second, third and fourth pulleys, and a tensioning element. The pulleys each have a suture contact surface, which define a single plane. The third pulley is rotatable about this single plane. The first, second and third pulleys are all movable on the single plane. A suture is mounted in the suture tester such that one end is attached to the reciprocating drive member, it then passes to the first pulley, to the third pulley, to the second pulley and to the fourth pulley, before attaching to the tensioning element at the other end of the suture. The third pulley is then rotated and locked into place to form the desired number of suture wraps. The suture tester is started and causes the suture to rub against itself until it fails.
    • 用于评估外科缝合线的抗磨损性的缝线测试仪。 缝合线测试仪包括往复式驱动构件,第一,第二,第三和第四滑轮以及张紧元件。 滑轮每个都具有缝合接触表面,其限定单个平面。 第三皮带轮可围绕该单个平面旋转。 第一,第二和第三皮带轮都可以在单个平面上移动。 将缝合线安装在缝合线测试器中,使得一端附接到往复式驱动构件,然后在将连接到张紧元件的第一滑轮,第三滑轮,第三滑轮,第二滑轮和第四滑轮 另一端缝合。 然后将第三滑轮旋转并锁定就位以形成所需数量的缝合线。 启动缝合线测试仪,并使缝合线自身摩擦直至失效。

    • According to an aspect of the present disclosure, an endoscopic surgical device is provided and includes a handle assembly; a tube assembly operatively supported on and extending from the handle assembly, the tube assembly defining a longitudinal axis; an articulation assembly operatively supported on and extending from a distal end of the tube assembly; and a tool assembly operatively supported on and extending from a distal end of the articulation assembly. In use, a rotation of the handle assembly about the longitudinal axis results in a concomitant rotation of the tool assembly; an actuation of the handle assembly in a particular manner results in a concomitant actuation of the tool assembly; and a pivoting of the handle assembly in any off-axis direction relative to the longitudinal axis results in a concomitant articulation of the tool assembly via the articulation assembly.
