Abstract
The invention discloses a three-hole anchor with a thread. The three-hole anchor with the thread comprises an anchor body, the upper end face of the anchor body is provided with an inner hexagonal hole groove, and a thread is arranged on the outer wall of the lower portion of the anchor body. Three thread penetrating holes are evenly distributed in the outer wall of the upper portion of the anchor body at the same height, the different side faces of the thread penetrating holes and the inner hexagonal hole groove are vertically communicated, and outlets of adjacent thread penetrating holes are arranged in an angle of 120 degrees. The upper end of an inlet and the upper end of the outlet of each thread penetrating hole are respectively and vertically provided with a thread groove, the upper end of each thread groove is communicated with the lower end face of the anchor body, and the lower end of each thread groove is communicated with the thread penetrating holes. Through above mode, an extensor digitorum brevis vtendon stopping point face can be rebuilt, the contact of a muscle tendon and the face of a bone and the dissection coupling relation are recovered, original functions can be recovered after operation, healing of the muscle tendon is fast, and breakage can not happen easily.
Description
Technical field
The present invention relates to a kind of improvement of band wire holdfast, particularly one and can rebuild extensor tendon stop face, recover tendon and contact with the face of bone and its dissection relationship in a mutual action, the postoperative original function that recovers, bone healing process of tendons is fast, not three pore area line holdfasts of easy fracture.
Background technology
Holdfast reconnects soft tissue and bone by suture clinically, and holdfast is imbedded stationary burst tendon tissue in sclerotin, to reach the object of tendon knitting.At present, clinical conventional holdfast can be divided into two kinds of metal anchoring nail and biodegradable holdfasts from material.Metal anchoring nail is mostly Titanium holdfast, and fraction is rustless steel holdfast, and titanium is inert metal, and histocompatibility is got well and enough initial constant intensities are provided.The material source of biodegradable holdfast is polylactic acid (PLA) mostly.PLA holdfast is absorbed by body after implanting for general about 2 years completely.
Band wire holdfast of the prior art, rebuilds extensor tendon stop and is point-like reparation, recovers tendon and contacts with the point-like of bone, and its Postoperative Bone healing process of tendons is slow, and healing is stretched and referred to that strength weakens, and easily ruptures again.
Summary of the invention
The technical problem that the present invention mainly solves is to provide one can rebuild extensor tendon stop face, and recover tendon and contact with the face of bone and its dissection relationship in a mutual action, the postoperative original function that recovers, bone healing process of tendons is fast, not three pore area line holdfasts of easy fracture.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of three pore area line holdfasts, comprise: holdfast body, the upper surface of described holdfast body is provided with inner hexagonal hole groove, the outer wall of the bottom of holdfast body is provided with screw thread, on the sustained height of the outer wall on the top of described holdfast body, be evenly equipped with 3 through wires holes, vertical the communicating of not same side of described through wires hole and inner hexagonal hole groove, and between the outlet of adjacent through wires hole, become 120 degree settings, the import of described through wires hole and the upper end of outlet are all vertically provided with wire casing, described wire casing upper end is communicated with holdfast body upper surface, lower end is communicated with through wires hole.
Preferably, the width of described inner hexagonal hole groove is not less than 3/4 of holdfast body upper surface diameter.
The invention has the beneficial effects as follows: a kind of three pore area line holdfasts of the present invention can be rebuild extensor tendon stop face, recover tendon and contact with the face of bone and its dissection relationship in a mutual action, the postoperative original function that recovers, bone healing process of tendons is fast, not easy fracture.

The structure cutaway view of the A-A that accompanying drawing 2 is Fig. 1;
Accompanying drawing 3 is top views of Fig. 1;
Wherein: 1, holdfast body; 2, wire casing; 3, through wires hole; 4, screw thread; 5, inner hexagonal hole groove.
detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1 to Fig. 3, the embodiment of the present invention comprises:
A kind of three pore area line holdfasts, comprising: holdfast body 1, and it is conical that described holdfast body 1 is roughly; The upper surface of described holdfast body 1 is provided with inner hexagonal hole groove 5, the outer wall of the bottom of holdfast body 1 is provided with screw thread 4, on the sustained height of the outer wall on the top of described holdfast body 1, be evenly equipped with 3 through wires holes 3, vertical the communicating of not same side of each through wires hole 3 and inner hexagonal hole groove 5; And between the outlet of adjacent through wires hole 3, become 120 degree settings.
On the inwall of the inner hexagonal hole groove 5 of the described outlet that is provided with through wires hole 3, be provided with vertically wire casing 2; The lower end of described wire casing 2 is communicated with the outlet of through wires hole 3, and upper end is communicated with the upper surface of holdfast body 1; In the external wall of upper portion of described holdfast body 1, import corresponding and each through wires hole 3 is all provided with wire casing 2 vertically; The lower end of described wire casing 2 is communicated with the import of through wires hole 3, and upper end is communicated with the upper surface of holdfast body 1; The width of described inner hexagonal hole groove 5 is not less than 3/4 of holdfast body 1 upper surface diameter, and the width of inner hexagonal hole groove 5 is larger, and the face that three through wires holes 3 form is just larger, and the effect of reparation is just better.
When operation, holdfast body 1 is fixed on bone, each through wires hole 3 penetrates suture respectively, and the two ends that make suture embed respectively in the wire casing 2 being connected with the import of through wires hole 3 and the outlet of through wires hole 3, again extensor tendon stop is passed in the two ends of suture, and tie a knot in the upper end at extensor tendon stop, make extensor tendon stop be fixed on bone surface.
The invention has the beneficial effects as follows: a kind of three pore area line holdfasts of the present invention can be rebuild extensor tendon stop face, recover tendon and contact with the face of bone and its dissection relationship in a mutual action, the postoperative original function that recovers, bone healing process of tendons is fast, not easy fracture.
Below be only concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on rights protection scope of the present invention.
