Anchor line in through wires hole, breaks anchor line.
Improve again, the trough is along the axially arranged of cylindrical portion.Along the axially arranged trough of cylindrical portion, simplify manufacture
Technique, it is convenient to produce in batches；Meanwhile, can convenient two free ends for disposing anchor line when use.
Improve again, the bottom surface of the trough is cambered surface.Connecting through wires hole and trough by cambered surface can prevent anchoring
Line is cut off by sharp side.
Improve again, the lower end periphery for stating conus portion is provided with least one axially disposed chip area with cutting edge.Row
Discarded bone bits can be discharged by bits groove, facilitate being screwed into for anchor studs.
Improve again, the chip area there are three, and the conical surface along conus portion is uniformly distributed.Three are uniformly distributed simultaneously along the conical surface
Chip area with cutting edge can improve the concentricity of cutting edge, anchor studs is preferably twisted along the bone groove for opening up in advance is concentric
Enter, effectively prevent anchor studs crooked, it is locked with bone.
Finally improve, the external screw thread is the downward saw-tooth thread of hypotenuse.The downward saw-tooth thread of hypotenuse can be more
Plus anchor studs are easily screwed into, and can effectively prevent anchor studs from coming off.
Compared with prior art, the utility model has the advantage of：When this anchor studs is used, anchor line is passed through into threading first
Hole, then two free ends of anchor line are passed from top surface after trough, the mid portion of anchor line is placed in trough
Will not contact with soft tissue, anchor studs are screwed into groove cooperation is driven by bone by bottle opener, can be by anchor studs when being screwed into
It is threaded into top surface concordant with bone face, such anchor studs would not protrude bone face, is urged to surrounding tissue or affects attractive in appearance.Simultaneously
The lower end of anchor studs is conus portion, convenient to apply active force, anchor studs is easily screwed into.
