Abstract

The invention discloses an anchor rivet with a wire. The anchor rivet comprises an anchor rivet body, wherein the upper part of the anchor rivet body is in a cylinder shape, the lower part of the anchor rivet body is in a conical shape, the upper end surface of the anchor rivet body is provided with a hexagon-socket hole groove, the outer wall of the lower part of the anchor rivet body is provided with screw threads, wire passing holes are uniformly formed in positions, at the same height, of the outer wall of the upper part of the anchor rivet body, the wire passing holes are vertically communicated with the different side surfaces of the hexagon-socket hole groove, the upper ends of inlets and outlets of the wire passing holes are respectively and vertically provided with wire grooves, the upper end of each wire groove is communicated with the upper end surface of the anchor rivet body, and the lower end of each wire groove is communicated with a corresponding wire passing hole. Through adopting the mode, the anchor rivet has the advantages that an extensor tendon stop point surface can be rebuilt, the expansion force of the anchor rivet is reduced, the injury to the bone caused by the anchor rivet is reduced, meanwhile, the plurality of wire passing holes are adopted, the direction of the wire passing holes in the anchor rivet does not need to be regulated after the anchor rivet is implanted into the bone, the fixation is convenient, and in addition, the fixation of extensor tendon stop points is more stable.

Description

A kind of band wire holdfast
Technical field
The improvement, particularly one that the present invention relates to a kind of band wire holdfast can rebuild extensor tendon stop face; Reduce the expansive force of holdfast, reduce holdfast to the damage of bone, simultaneously, owing to being provided with multiple through wires hole, do not need to adjust the through wires hole direction on holdfast after holdfast can be made to implant bone, convenient fixing, and the more stable band wire holdfast that extensor tendon stop can be made to fix.
Background technology
Soft tissue and bone are reconnected by suture by holdfast clinically, and holdfast imbeds stationary burst tendon tissue in sclerotin, to reach the object of tendon-bone healing.At present, clinical conventional holdfast can be divided into metal anchoring nail and biodegradable holdfast two kinds 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 provided enough initial constant intensities.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, recover the point-like contacts of tendon and bone, its Postoperative Bone healing process of tendons is slow, and finger diminished strength is stretched in healing, easily ruptures again, expansive force is large, comparatively large to bone impingement, and needs the direction of finely tuning through wires hole after implanting bone.
Summary of the invention
The technical problem that the present invention mainly solves is to provide one can rebuild extensor tendon stop face; Reduce the expansive force of holdfast, reduce holdfast to the damage of bone, simultaneously, owing to being provided with multiple through wires hole, do not need to adjust the through wires hole direction on holdfast after holdfast can be made to implant bone, convenient fixing, and the more stable band wire holdfast that extensor tendon stop can be made to fix.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of band wire holdfast, comprising: ground anchor body, and the top of described ground anchor body is cylindrical, and bottom conically; The upper surface of described ground anchor body is provided with inner hexagonal hole groove, and the outer wall of the bottom of ground anchor body is provided with screw thread, and the sustained height of the outer wall on the top of described ground anchor body is evenly equipped with through wires hole, and described through wires hole communicates with the not same side of inner hexagonal hole groove is vertical; The not same side of described inner hexagonal hole groove is equipped with several through wires holes; The import of described through wires hole and the upper end of outlet are all vertically provided with wire casing, and described wire casing upper end is communicated with ground anchor body upper surface, and lower end is communicated with through wires hole.
Preferably, the not same side of described inner hexagonal hole groove is equipped with 2 through wires holes.
The invention has the beneficial effects as follows: a kind of band wire holdfast of the present invention can rebuild extensor tendon stop face; Reduce the tensile force of holdfast, reduce holdfast to the damage of bone, meanwhile, owing to being provided with multiple through wires hole, do not need to adjust the through wires hole direction on holdfast after holdfast can be made to implant bone, convenient fixing, and fixing more stable of extensor tendon stop can be made.

Accompanying drawing 1 is the structural representation of a kind of band wire holdfast of the present invention;
Accompanying drawing 2 is the top view of Fig. 1;
Accompanying drawing 3 is the structure sectional view of the A-A of Fig. 2;
Wherein: 1, ground anchor 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, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1 to Fig. 3, the embodiment of the present invention comprises:
A kind of band wire holdfast, comprising: ground anchor body 1, the top of described ground anchor body 1 is cylindrical, and bottom conically, is conducive to punching convenient, and reduces tensile force; The upper surface of described ground anchor body 1 is provided with inner hexagonal hole groove 5, the outer wall of the bottom of ground anchor body 1 is provided with screw thread 4, the sustained height of the outer wall on the top of described ground anchor body 1 is evenly equipped with 3 through wires holes 3, each through wires hole 3 communicates with the not same side of inner hexagonal hole groove 5 is vertical.The not same side of described inner hexagonal hole groove 5 is equipped with 2 through wires holes 3.
The described inwall being provided with the inner hexagonal hole groove 5 of the outlet of through wires hole 3 is provided with wire casing 2 vertically; The lower end of described wire casing 2 and the outlet of through wires hole 3, upper end is communicated with the upper surface of ground anchor body 1; In the external wall of upper portion of described ground anchor body 1, import that is corresponding and each through wires hole 3 is provided with wire casing 2; The lower end of described wire casing 2 and the inlet communication of through wires hole 3, upper end is communicated with the upper surface of ground anchor body 1.
During operation, ground anchor body 1 is fixed on bone, suture penetrates by each through wires hole 3 respectively, and make the two ends of suture embed in the wire casing 2 be connected with the outlet of through wires hole 3 with the import of through wires hole 3 respectively, again extensor tendon stop is passed at the two ends of suture, and tie a knot in the upper end of extensor tendon stop, make extensor tendon stop be fixed on bone surface.
The invention has the beneficial effects as follows: a kind of band wire holdfast of the present invention can rebuild extensor tendon stop face; Reduce the tensile force of holdfast, reduce holdfast to the damage of bone, meanwhile, owing to being provided with 12 through wires holes, do not need to adjust the through wires hole direction on holdfast after holdfast can be made to implant bone, convenient fixing, and fixing more stable of extensor tendon stop can be made.
Below be only embody rule example of the present invention, protection scope of the present invention is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within rights protection scope of the present invention.
