A knot may be formed in suture material using a device having an elongated body with a longitudinal axis and a holder. A rail portion of the suture material is secured with a first grasper on the elongated body and a non-rail portion of the suture material is secured with a second grasper on the holder. A plurality of helical windings may be created with the non-rail portion. Detaching the holder from the elongated body in a motion away from the longitudinal axis of the elongated body completes the knot. The holder may be wrapped around the elongated body in a knot-forming pattern.本發明利用一裝置在縫線材料中打結，該裝置具有一延伸本體以及一持線件，延伸本體具有一縱軸。以一第一抓持器將縫線材料的一軌道部固定於延伸本體，以及以一第二抓持器將縫線的一非軌道部固定於持線件。複數螺旋線圈可利用非軌道部而建立。將持線件以一遠離延伸本體的縱軸方向移動而從延伸本體拆卸以完成打結。持線件以一結形成的態樣而沿著延伸本體周圍纏繞。
