By adopting the technical scheme, the utility model has the following advantages and positive effects compared with the prior art:
the combined type band wire anchor comprises the main anchor and the auxiliary anchor, and the main anchor and the auxiliary anchor are implanted into a target object during implantation, so that compared with the traditional band wire anchor, the band wire anchor provided by the utility model is firmer after implantation. In addition, in the case of the optical fiber,
(1) After the anchor is implanted, an operator needs to knot the suture, the suture tensioning operation is performed during knot tying, the traditional anchor is likely to loosen or even fall off during operation, particularly, the wedge-shaped anchor is easy to pull out when the wedge-shaped anchor is pulled through the suture at a certain angle (the angle is called as a dead angle), but the operator is difficult to clearly know and control the implantation angle of the wedge-shaped anchor during knot tying, so that the wedge-shaped anchor is very easy to pull out when the wedge-shaped anchor is pulled through the suture and is just in the dead angle during knot tying. The axes of the main anchor and the auxiliary anchor in the application are not coincident and are not parallel, so that the wedge-shaped anchor problem is avoided, the risk of falling out of the anchor is reduced, and the fixing strength of the anchor is increased.
(2) Conventional forms of threaded anchors require large blade threaded anchors to enhance their fixation to cancellous bone when needed for use with cancellous bone. In order to ensure the structural strength of the anchor, the anchor is usually made of metal materials, and PEEK, absorbable materials and other materials which are more beneficial to clinic are difficult to use. The metal material has larger difference between the elastic modulus and the bone of the human body, strong foreign body sensation and is unfavorable for clinical development. If the combined type band wire anchor provided by the utility model is adopted, the main anchor and the auxiliary anchor are in a cross combination mode, so that the firmness between the combined type band wire anchor and a target object after being integrally implanted is improved, the threaded blades on the main anchor and the auxiliary anchor do not need to be made into a special size, and the combined type band wire anchor can be made of PEEK, absorbable materials and other materials which are more beneficial to clinic. (it should be noted that the scope of applicability of the combination type suture anchor provided by the utility model is not limited to cancellous bone, and is suitable for most occasions requiring repair treatment of the suture anchor, such as metacarpophalangeal bones, knee joints, shoulder joints, etc.)
(3) Because the anchoring of the combined type band wire anchor can be stronger than that of the traditional band wire anchor, if the combined type band wire anchor is adopted for the same target object, the single size of the main anchor and the auxiliary anchor can be correspondingly reduced, the implantation depth is relatively reduced, and the trauma to the target object is also reduced. When a plurality of combined band-line anchors are needed by adopting the traditional band-line anchors, the number of the combined band-line anchors used for the same target object is smaller than that of the traditional band-line anchors due to the strong anchoring capability of the combined band-line anchors, so that the trauma of the target object can be reduced.
(4) Conventional band wire anchors, when implanted, are typically implanted at a vertical or near vertical angle to the target object. When the combined type band wire anchor is implanted, the main anchor and the auxiliary anchor are in a crossed shape and are implanted into the target correspondingly, so that the included angles between the main anchor and the auxiliary anchor and the surface of the target object are relatively smaller during implantation, and the punching depth of the combined type band wire anchor is shallower during implantation.
