摘要： A medical device for ligation or approximating tissue is disclosed. The device has a cannula with proximal and distal ends. The distal end of the cannula has a beveled surface, and the cannula has first and second channels, the first channel extending axially through it, and the second channel extending from the beveled surface to the first channel. The device includes a suture with a slide end and a distal loop, as well as a slip knot securing the loop to the slide end. The slide end is threaded thorough the first and second channels of the cannula and it protrudes from the proximal end of the cannula. In addition, the device incorporates means for securing the positioning of the slide end of the suture in the first channel of the cannula. The device may optionally have a frangible proximal end wherein the proximal end of the suture is mounted to the frangible proximal end.The device is particularly well adapted for use during endoscopic surgery when it is necessary to perform operative procedures through small openings in the body. The device is easy to maneuver and to position, and does not require the user to make the suture knot outside the body.
摘要翻译：公开了一种用于结扎或近似组织的医疗装置。该装置具有近端和远端的套管。套管的远端具有倾斜的表面，并且套管具有第一和第二通道，第一通道轴向地延伸通过它，并且第二通道从斜面延伸到第一通道。该装置包括具有滑动端和远端环的缝线，以及将环固定到滑动端的滑结。滑动端穿过套管的第一和第二通道，并从插管的近端突出。此外，该装置包括用于固定缝合线的滑动端部定位在插管的第一通道中的装置。该装置可以可选地具有易碎的近端，其中缝合线的近端安装到易碎的近端。当需要通过身体中的小开口执行手术操作时，该装置特别适用于内窥镜手术期间使用。该装置易于操纵和定位，并且不需要用户将缝合线结在身体外部。
