Knot-free anchor and implantation device thereof

Abstract

The invention relates to the field of medical devices, and discloses a knot-free anchor and an implantation device thereof. The knot-free anchor comprises an anchor body and a threading portion located at a top end position of the anchor body, a first external thread is formed on an outer peripheral wall of the anchor body, and a threading hole is formed on the threading portion. The structure ofthe implantation device comprises: a rotary handle including an implantation rod for connecting with a knot-free anchor and an implantation handle coaxially connected with the implantation rod; And asupport handle including a support sleeve and a grip handle coaxially connected to the support sleeve. The knot-free anchor of the invention can make the fixation effect of the suture better, so thatthe knot-free anchor can more stably and effectively fix the soft tissue on the bone, thereby promoting the rapid repair and reconstruction of the soft tissue. The knot-free anchor of the invention can make the fixation effect of the suture better, so that the knot-free anchor can more stably and effectively fix the soft tissue on the bone, thereby promoting the rapid repair and reconstruction ofthe soft tissue.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a knot-free anchor and an implantation device thereof. Background technique [0002] Knot-free anchor is a surgical implant commonly used clinically for soft tissue repair or reconstruction. When the soft tissue of the human body is torn from the bone and needs to be repaired, the surgeon usually uses sutures to suture and fix the soft tissue that needs to be reattached, and then fixes the free end of the suture to the bone through an anchor to achieve the soft tissue. Fixed to the bone to achieve the purpose of repairing soft tissue. [0003] The structure of the commonly used knot-free anchor usually includes an anchor body, an external thread is formed on the peripheral wall of the anchor body, and an implant hole for cooperating with an external implanter is formed inside the anchor body. The commonly used knot-free anchor threading methods mainly include two types, one is th...

Problems solved by technology

For the former threading method, when the suture passes through the implantation hole of the knot-free anchor, the implantation rod of the implanter also needs to be inserted into the implantation hole to realize the implantation of the anchor. Therefore, the implantation During the implantation of the anchor, the rod will wear the suture in the implantation hole to a certain extent, which is not conducive to the postoperative recovery of the patient

For the latter threading method, it only takes time to wind the suture thread on the external thread on the one hand, and on the other hand, the suture thread cannot be firmly fixed on the anchor, so that the suture thread can not be firmly fixed on the anchor when the anchor is implanted. It is easy to fall off during or after the operation, which increases the difficulty of the operation. Once the suture falls off, it will not be conducive to the patient's postoperative recovery

In addition, for the above two threading methods, since the implant rod of the implanter is thinner and longer, it is easy to cause non-directional deflection of the implantation angle of the anchor during the implantation process, and the operator needs to repeatedly adjust the anchor. The angle of implantation of the anchor may even require repeated removal or implantation of the anchor to complete the implantation of the anchor, resulting in low implantation efficiency of the anchor, which is not conducive to the smooth operation of the patient.
