Abstract
The utility model discloses an anchorage nail tool comprising a handle and a tool head, wherein the tool head comprises a connecting rod connected with the handle; one end of the connecting rod is connected with the handle, and the other end of the connecting rod is provided with a clamping head; the clamping head comprises a chuck and a stiff shaft, and the peripheries of the chuck and the stiff shaft are provided with a fastening sleeve; the chuck is of an elongated cone with a central shaft hole, and the wall surface of the elongated cone is provided with a plurality of sectional ditches along the axial direction; the fastening sleeve can move along the axial direction of the stiff shaft. The anchorage nail tool disclosed by the utility model is adjustable, so that the implanting operation of an anchorage nail is more convenient and precise.
Description
Technical field
This utility model belongs to mouth cavity orthodontic field of tool, is specifically related to the setting tool of anchorage nail for a kind of mouth cavity orthodontic.
Background technology
Since the pioneering pure titanium material spiral-shafted implant of Sweden Branemark is by since universally acknowledged, obtained good therapeutic treatment effect, because it has good biocompatibility and mechanical strength, maintenance is good, corrosion-resistant, after implant into body, can form good interface with osseous tissue, mucosal tissue and skin, can remain on for a long time in human body jawbone, and be widely used.Utilize at present pure titanium material spiral-shafted implant also very general for correction implant anchorage.Because micro screw implantation body is a kind of anchorage with the feature such as firm, comfortable, can replace traditional anchorage, in adult's defect of dentition patient, bring into play powerful anchorage effect, expanded the indication of orthodontic.Concrete employing operation method is fixed correcting technology as anchorage and completes the whole process of rescuing in plantation nail implantation alveolar bone.This kind of method have advantages of that anchorage effect stability, art formula are simple, shorten correction course for the treatment of.Correction section adopts the patient of this technology more and more.
The cap portion of following closely due to anchorage is all generally the gengons such as hexagon or tetragon, while at present anchorage nail being implanted to the pre-positions such as alveolar bone, all adopts the polygon set screw the Knife tools such as existing hexagon or four limits.Because existing polygon set screw the Knife tool adopts polygon head in fixing, interior polygon head, can be slightly larger than anchorage head of a nail portion size for anchorage head of a nail portion being inserted in.So adopt so existing instrument to implant anchorage nail, easily cause anchorage nail to plant partially or occur the inaccurate situation of implantation position.
Summary of the invention
For the problem existing in background technology, this utility model provides a kind of adjustable anchorage nail setting tool.Anchorage nail instrument of the present utility model, makes the implant procedure of anchorage nail convenient, accurate.
The technical solution adopted in the utility model is as follows: a kind of anchorage nail instrument, comprise handle and tool heads, and described tool heads comprises the connecting rod of connecting handle, and connecting rod one end is connected with handle, and the other end is provided with clamping head; Described clamping head comprises chuck and strength axle, and neck axle and chuck periphery are provided with adapter sleeve; Described chuck is the microscler cone with central shaft hole, on microscler cone wall, is provided with vertically several profile grooves; Adapter sleeve can move axially along strength axle.
Anchorage nail instrument of the present utility model, described strength axle middle part is provided with screw thread, and corresponding adapter sleeve inwall is provided with matching thread; And the screw thread of the screw thread on strength axle and anchorage nail is left-hand thread.
Anchorage nail instrument of the present utility model, the central shaft hole of described chuck is the polygons such as hexagon or tetragon.
The utlity model has following beneficial effect: chuck and the strength axle periphery of due to anchorage of the present utility model, following closely instrument are provided with adjustable adapter sleeve, when anchorage head of a nail portion enters after polygon central shaft hole, by adapter sleeve toward chuck direction rotation, can anchorage stickfast firmly be fixed on chuck, while implanting like this anchorage nail, can be more accurate.Further, after anchorage nail is implanted, as long as by adapter sleeve reverse rotation, can easily move out of instrument.Used anchorage nail instrument of the present utility model, that for size, smiles in time also can fix accurately for screw, and easy to operate, greatly facilitates the clinical manipulation that dentistry is corrected doctor.
