    • A device for the anchoring of a suture in tissue includes a guide sleeve, a sonotrode, an anchor and the suture. The guide sleeve has a distal part with a smaller cross section and a proximal part with a larger cross section. The sonotrode extends through the lumen of the guide sleeve and has a distal end and a proximal end, the proximal end being designed for coupling the sonotrode to a vibration source (e.g. an ultrasonic device). The anchor is arranged at the distal end of the device and includes an anchor foot and an anchoring sleeve sitting on a shoulder of the anchor foot. The anchoring sleeve consists of a material which is liquefiable through mechanical vibrations. A middle portion of the suture runs through the anchor foot and two end portions of the suture are attached to the guide sleeve. The anchoring sleeve is clamped or clampable between the anchor foot and a pushing sleeve or the sonotrode or the guide sleeve. The device is particularly suitable for the anchoring of sutures in bone tissue.
    • 用于将缝合线锚固在组织中的装置包括导向套筒,超声焊条,锚固件和缝合线。 引导套筒具有较小横截面的远端部分和具有较大截面的近端部分。 超声波延伸穿过导向套筒的内腔并具有远端和近端,近端被设计用于将超声波发生器耦合到振动源(例如超声波装置)。 锚固件布置在装置的远端,并且包括锚脚和位于锚脚的肩部上的锚定套。 锚定套筒由可通过机械振动液化的材料组成。 缝合线的中间部分穿过锚脚,并且缝合线的两个端部附接到引导套筒。 锚定套筒被夹紧或夹紧在锚脚和推动套筒或超声波发生器或引导套筒之间。 该装置特别适用于将缝合线锚固在骨组织中。
