Description
Technical field
This utility model belongs to mouth cavity orthodontic field of tool, is specifically related to the setting tool of a kind of mouth cavity orthodontic anchorage nail.
Background technology
Since pure titanium material spiral-shafted implant pioneering for Sweden Branemark is by since universally acknowledged, have been achieved for good therapeutic treatment effect, because it has good biocompatibility and mechanical strength, maintenance is good, corrosion-resistant, good interface can be formed with osseous tissue, mucosal tissue and skin after implanting human body, can be maintained at for a long time in human body jawbone, and be widely used.The most universal for correction implant anchorage currently with pure titanium material spiral-shafted implant.Owing to microfiltration concentrated broth is a kind of anchorage with the feature such as firm, comfortable, it can instead traditional anchorage, adult dentition defect patient plays powerful anchorage effect, expands the indication of orthodontic.Concrete use operation method to be implanted by plantation nail in alveolar bone to complete whole to rescue process as anchorage cooperation fixed orthodontic technology.This kind of method has anchorage effect stability, art formula is simple, the advantage that shortens the correction course for the treatment of.Correction section uses the patient of this technology to get more and more.
Owing to the cap portion of anchorage nail is typically all the gengon such as hexagon or tetragon, when at present anchorage nail being implanted the pre-positions such as alveolar bone, all use the polygon location instruments such as existing six limits or four limits.But the currently used general volume of set screw the Knife tool is relatively big, doctor, to the most inconvenient when front and back grinding one's teeth in sleep or operate at tongue side, has a strong impact on the precision of implantation position.
Summary of the invention
For problem present in background technology, this utility model provides a kind of compact, is difficult to again the anchorage nail instrument of landing in can going deep into patient oral cavity.
The technical solution adopted in the utility model is as follows: a kind of anchorage nail instrument preventing landing, including handle and tool heads, described tool heads includes that neck axle and the clamping head being connected on neck axle, neck axle and clamping head are the most cylindrical；Offer on the bottom surface that described clamping H&N axle connects one along the radially the most through groove of cylinder, the end face of clamping head then offers one along cylinder axis to polygonal grooves；The through depth of groove of radial direction on clamping head bottom surface is always till clamping head bottom surface extends to polygonal grooves groove bottom, and radially through groove is through with the bottom land intersection of polygonal grooves；It is fixed with two flexible fastening bars protruded on neck axle, protrudes flexible fastening bar and coordinate with radially through groove both sides, inside and outside radially through groove, elastic displacement radially occurs.
A kind of anchorage nail instrument preventing landing of the present utility model, the two ends bottom land that the through groove of described radial direction does not intersects with the bottom land of polygonal grooves is arc-shaped, two corresponding flexible fastening bars are upper coarse and lower fine structure, and upper thick part is arc-shaped and two ends form fit.
A kind of anchorage nail instrument preventing landing of the present utility model, the width of the through groove of described radial direction is about the 1/4 of cylinder diameter.
A kind of anchorage nail instrument preventing landing of the present utility model, is additionally provided with bracelet line fixed structure on handle.Described bracelet line fixed structure is one groove around handle outer wall, and bracelet line is embedded in groove.
A kind of anchorage nail instrument preventing landing of the present utility model, described bracelet line fixed structure can also is that the hook being arranged on handle, bracelet line are tied up and be located on hook.
A kind of anchorage nail instrument preventing landing of the present utility model, described handle and tool heads are all in cylindrical shape, and 1/10 to 1/4 that the cylinder diameter of tool heads is handle cylinder diameter.
A kind of anchorage nail instrument preventing landing of the present utility model, is connected by conical transition section between described handle and tool heads.
This utility model has the advantages that
Following closely instrument due to the anchorage of the present invention and change conventional large volume, shape is small and exquisite, thus whole instrument can be goed deep into the oral cavity of patient in Clinical practice so that the operation to front and back grinding one's teeth in sleep more accurately facilitates, and the operation for tongue side is also such.
Owing to the anchorage nail instrument of the present invention is with groove of accidentally dropping, so during using, coil can be had to be fixed on doctor on hand, will not slide because of hands or other reasons makes anchorage nail instrument fall into patient oral cavity, cause accidentally swallowing, make operation safer, thus solve potential safety hazard.

Detailed description of the invention
As it can be seen, a kind of anchorage of the present utility model nail instrument includes tool heads 1, handle 2 and the bracelet line fixed structure being arranged on handle 2.Bracelet line fixed structure is the groove 5 of accidentally dropping together around handle outer wall, and bracelet line is bundled in accidentally drops on groove 5.In specific implementation process, bracelet line one end is bundled in accidentally drops on groove 5, and the other end also needs to binding or is enclosed within the wrist of doctor.Bracelet line fixed structure can also is that the hook being arranged on handle, bracelet line one end are tied up and be located on hook, and the other end is bound or is enclosed within the wrist of doctor.Certainly being not limited to both the above mode in being embodied as, all structures similar with aforesaid way belong to protection domain of the present utility model.
Handle 2 and tool heads 1 are all in cylindrical shape, and 1/10 to 1/4 that the cylinder diameter of tool heads 1 is handle 2 cylinder diameter, specifically can adjust according to actually used situation.It is connected by conical transition section 3 transition between handle 2 with tool heads 1, and is additionally provided with decorative pattern 4 on handle 2 outer circumference surface, the frictional force between hands and handle can be increased, prevent landing.
Tool heads 1 includes neck axle 8 and clamping 6, and clamping 6 is welded on neck axle 8, overall in cylindrical shape as neck axle 8.Offer on cylinder clamping 6 bottom surface welded with neck axle 8 one along the cylinder the most through groove 7 of radial direction, the width of described groove 7 is about the 1/4 of cylinder diameter.Then have on the end face of cylinder clamping 6 one along cylinder axis to the hexagon offered or tetragon groove 10.Hexagon or tetragon groove 10 are used for fixing anchorage nail.Till the degree of depth of groove 7 extends to the groove bottom of groove 10 always from cylinder clamping 6 bottom surface welded with neck axle 8, and the part that groove 7 intersects with the groove bottom of groove 10 is through, the groove bottom (the groove bottom part that i.e. groove 7 does not intersects with groove 10) at groove 7 two ends is in arc-shaped.
Two prominent flexible fastening bars 9 it are fixed with, when, after neck axle 8 and clamping 6 welding, described flexible fastening bar 9 is placed exactly in the two ends of groove 7 on neck axle 8.And described flexible fastening bar 9 is in upper coarse and lower fine structure, and upper thick part has arc-shaped and protrudes, and just the arc-shaped slot Bottom Shape with groove 7 two ends coordinates.Anchorage is followed closely during putting into, under force, two flexible fastening bars 9 at groove 7 two ends will be coordinated to push to outside cylinder, after anchorage nail is put into, two flexible fastening bars 9 return to original form under elastic reaction, thus by anchorage nail being fixed in clamping head steadily.As when anchorage to be extracted is followed closely also being, firmly latter two flexible fastening bar 9 can revert to again original form to cylinder lateral offset the most again under elastic reaction after taking out completely.
