    • The invention relates to an easily retrieved biological specimen pouch. The said easily retrieved biological specimen pouch of the invention comprises a flexible wall, an open end and a closed end, and the specimen pouch can receive a biological specimen; A) The flexible wall of the open end of the specimen pouch has discontinuous serration; B) On the said serration, there are slots through which an open and retrieval string or an open spring or a retrieval noose can pass. As the open end of the specimen pouch is provided with a flexible wall of discontinuous serration, and the open and retrieval string or the retrieval noose passes through the slots on the discontinuous serration of the flexible wall of the open end of the specimen pouch, when the open and retrieval string is pulled towards an outer sheath to retrieve the specimen pouch of the invention, the bulk of contracted open end is reduced due to the discontinuous serration of the flexible wall of the open end. It is easy to close the open end of the specimen pouch, and convenient to retrieve the specimen pouch into the outer sheath or extract it through a small incision. The specimen pouch of the invention is simple, convenient, safe and efficient.
    • 本发明涉及容易回收的生物样本袋。 本发明的所述容易回收的生物样本袋包括柔性壁,开口端和封闭端,并且样本袋可以容纳生物样本; A)试样袋开口端的柔性壁具有不连续的锯齿状; B)在上述锯齿处,有一个槽,一个开放的和取出的绳子或一个开放的弹簧或一个取出的套索可以通过。 由于试样袋的开放端设置有不连续锯齿的柔性壁,开放和取出的绳索或取回的索糖通过样品袋开放端的柔性壁的不连续锯齿上的槽,当 打开和取出的绳子被拉向外护套以取回本发明的试样袋,由于开口端的柔性壁的不连续的锯齿,收缩的开口端的大部分被减小。 容易关闭样品袋的开口端,方便将样本袋取回到外护套中或通过小切口提取。 本发明的样品袋简单,方便,安全,高效。

    • A grooved universal radial seal ring used in a trocar and a trocar are provided. The radial seal ring includes one or more easily-deformable grooves, one or more supporting areas capable of guiding surgical device movement, and a through hole, the supporting areas of the seal ring are connected by the easily-deformable grooves, a thickness of the easily-deformable grooves is much smaller than an average thickness of the supporting areas, so that when a surgical device is inserted along a cone-shaped guiding groove of the supporting areas, the easily-deformable grooves deform first and surround the surgical device because a wall thickness of the easily-deformable grooves is very small, thereby achieving a sealing effect. When the surgical device shakes, the supporting areas separated by the easily-deformable grooves also shake together, but the seal ring formed by the easily-deformable grooves still surrounds the surgical device, thereby always keeping a sealed state and achieving an excellent dynamic sealing effect. Particularly, the thickness of the easily-deformable grooves is small, not only a dynamic sealing effect is excellent, but also surgical device moving resistance is small. The trocar realizes any replacement among surgical devices with diameters being 12 millimeters (mm), 10 mm, and 5 mm, thereby bringing convenience to surgical operation.
    • 提供了一种用于套管针和套针针的开槽通用径向密封环。 径向密封环包括一个或多个容易变形的凹槽,一个或多个能够引导手术装置运动的支撑区域,以及通孔,密封环的支撑区域由容易变形的凹槽连接,厚度为 容易变形的凹槽远小于支撑区域的平均厚度,使得当手术装置沿着支撑区域的锥形引导槽插入时,容易变形的凹槽首先变形并围绕外科手术装置,因为 易变形槽的壁厚非常小,从而实现密封效果。 当手术装置摇动时,由容易变形的凹槽分开的支撑区域也摇动在一起,但由容易变形的凹槽形成的密封环仍然包围手术装置,从而始终保持密封状态并实现优异的动态密封效果 。 特别地,易变形槽的厚度小,不仅动态密封效果优异,而且手术装置的移动阻力小。 套管针实现直径为12毫米(10mm),10mm和5mm的手术装置之间的任何替换,从而为外科手术带来便利。
