Description
Technical field
The invention belongs to dental care field, relate to a kind of dentistry nail-fetching device, the dentistry implant after plantation takes out.
Technical background
Dentistry planting technology, through development for a long time, is recognized more and more widely.Owing to the many reasons such as, infected or client need are not likely to cause planting unsuccessfully by postoperative complication, planting location, need the taking-up from patient's mouth of plantation nail.Implantation body is brought into by carrier when implanting, and transmits moment of torsion by carrier, and implantation body can easily be screwed on dental bed bone.Implantation body once implants, it is desirable to implantation body is taken out, because not having to transmit the bridge of moment of torsion, has relative difficulty.Odontologist generally uses brute-force to be taken out by tooth implant with medical calm at present, the most not only operating difficulties, it is also possible to damages dental bed bone, injures the oral cavity of patient.
Summary of the invention
The present invention seeks to provide a kind of dentistry nail-fetching device for above-mentioned inconvenience, be that one can facilitate implantation body to take out, patient can be reduced again painful, it is simple to mass-produced dentistry nail-fetching device.
The present invention is achieved through the following technical solutions: a kind of dentistry nail-fetching device includes torsion head, nail-fetching device main body and central screw；Described torsion head outer surface is provided with flat filament or outer-hexagonal, it is simple to transmission moment of torsion, has positioning step hole inside torsion head, and top, positioning step hole diameter of bore is less than bottom diameter of bore；Described nail-fetching device body interior has stepped hole, stepped hole top diameter of bore is less than bottom diameter of bore, nail-fetching device main body upper end is provided with ratchet slot, it is easy to use ratchet spanner transmission moment of torsion and takes out implantation body, nail-fetching device lower body part is provided with the Mohs conical surface, being provided with boss on the Mohs conical surface, described boss may be configured as corner, hexagonal or anistree boss；Described central screw top is provided with positioning step, central screw top outside diameter is less than upper end outside diameter, central screw bottom is provided with step section, and central screw top outside diameter is less than step section outside diameter, is provided with the thread segment being connected with implantation body female thread bottom central screw.
Central screw is arranged in nail-fetching device main body stepped hole, the thread segment being connected with implantation body internal thread hole of central screw exposes stepped hole, it is connected with implantation body female thread when being easy to use, central screw top is enclosed within torsion head positioning step hole, uses welding manner to be welded with torsion crown end face on central screw top and is integrally fixed.
The operation principle of the present invention is: nail-fetching device first loads implantation body's endoporus, makes boss and implantation body's inner hole of nail-fetching device main body；Then nail-fetching device torsion head is turned clockwise until tightening；Again ratchet spanner is enclosed within the ratchet slot of nail-fetching device main body, rotating ratchet wrench counterclockwise, thus implantation body can be taken out from alveolar bone；Then ratchet spanner is taken off, rotate nail-fetching device torsion head counterclockwise (if moment is the biggest, instrument can be used to rotate flat filament face or hex surface), torsion head drives central screw upwards until the step surface of central screw encounters nail-fetching device main body endoporus step surface, now the thread segment bottom central screw does not the most completely disengage from implantation body's inner hole thread, torque axis is changed to axial force when screwing out by screw thread, nail-fetching device main body is upwards pushed up by the step section of central screw bottom, the nail-fetching device lower body part Mohs conical surface and boss is made to depart from implantation body's endoporus, thus nail-fetching device can be taken off from implantation body.
The invention has the beneficial effects as follows: one dentistry nail-fetching device of the present invention is reasonable in design, simple in construction, it is simple to produce in a large number is easy to operate.Solve current medical calm and take off the difficult problem that there is the risk of injury patient's mouth in implantation body.Have also contemplated that the nail-fetching device Mohs conical surface and the locked problem at implantation body's endoporus of boss after taking off implantation body, when having used screw thread derotation for this problem is ingenious, rotation torque is converted to axial force and ejects nail-fetching device main body, easily take off nail-fetching device.Not only relieve the worry of doctor, also reduce the misery that patient is unnecessary.
