Description

Chargeable artificial implanting machine

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of chargeable people's work post tooth machine of the implantable artificial artificial tooth of holing on the edentulous region alveolar bone.

At present domestic and international people's work post tooth, generally there is following point in the apparatus of boring implantable artificial artificial tooth on alveolar bone: (1) complex structure, cost an arm and a leg, the import machine generally is 20,000 yuan to 50,000 yuan, home-made machine is also wanted 8,000 yuan to 15,000 yuan.(2) 20 to 1 deceleration mobile phone dependence on import.(3) need many people's operations, rely on assistant or nurse's help, can not the regulated at will drill speed in the operator work, meet power failure by chance, no emergency power supply guarantees to perform the operation continues to finish.(4) handheld electrical machinery, lead, bar head can not high-pressure steam sterilizations, are unsuitable for basic unit doctor sterile working.(5) need water and air injection to reduce borehole temperature.The plantation work of artificial artificial tooth at present both at home and abroad is only limited at big city large hospital and hospital with good conditionsi and carries out, and the exodontia amount maximum be not at large hospital, but concentrate on basic hospital, therefore, people's work post tooth technology is spread to basic unit just becomes very necessary.

It is little that the purpose of this utility model provides a kind of volume, in light weight, and rotating speed is slow, and torsion is big, and price is low, the popular chargeable people's work post tooth machine that is easy to carry about with one.

This utility model is by direct current generator, change-speed gearing group, dentistry acute angle handpiece, compositions such as shell, lead and foot switch.

Elaborate below in conjunction with accompanying drawing.

Fig. 1 is this utility model structural representation.

Fig. 2 is this utility model ultimate principle circuit diagram.

Chargeable people's work post tooth machine of the present utility model, direct current generator (1) and change-speed gearing group (2) are sealed in the metal shell (3), shell (3) head is dentistry acute angle handpiece (4) fixedly, the rear portion connects lead (5), lead (5) other end is equipped with battery, the foot switch of control circuit board (6) in connecting.The slit of all connecting portions is all used the adhesive cementation of anti-boiling water, as is selected polyurethane epoxy resin for use in the shell (3).It is lubricated to be full of high temperature resistant, the butter that do not trickle in the shell,, does not ooze out not flowing below 130 ℃ as lithium matter high temperature butter, and non-volatile, steam enters motor and shortens electrical machinery life in the time of can preventing vapor sterilization like this.Battery can be selected cadmium nickel sealed cell for use, and it is standby to make emergent charging, all can use in the abnormal township hospital of power supply like this.Battery and control circuit board are assembled in the foot switch, can insert medical safe power supply 12V such as department of stomatology illuminating lamp or photocuring dental filling machine before using, 15V, charge on 24V or the radio cassette player commutator, during use as long as the surgical doctor moving foot switch that tramps with one's feet, the drill bit of planting the tooth mobile phone is promptly rotatable, firmly big more, speed up, can go to 150 rev/mins to speed controlling at per minute 20, the rotating speed of leaving descends, as long as can rotate, torsion foot energy drilling spongy bone, running voltage can be controlled between 6-12V, electric current 0.8A, also can change the high speed handpiece of inserting no change-speed gearing, rotating speed is brought up to 4500 rev/mins, be used for the dentistry polishing, or be used for orthopaedics boring.

Groundwork principle of the present utility model is: insert various medical safe supply hubs such as mouth illuminator when power-line plug, when connecting 12V or 15V alterating and direct current, cadmium nickel electric current charges voluntarily, when as long as the doctor steps on foot switch in operation, the ickel-cadmium cell discharge, machine operation, drill bit rotates, and motor was with the slow start of 6V voltage, when firmly big more when foot switch was connected, resistance decreasing, voltage rises and is 12V to the maximum, maximum current 0.8A, and a small-sized reversing switch is equipped with in the end of incoming cables of foot switch, as long as click with foot, drill bit can withdraw from the other direction.

This utility model kind tooth machine not charged source potential device and have the emergent charging power supply is not with water injector, and borehole temperature is in physiological range.But handgrip part comprises all vapor sterilization of motor, motor speed regulated at will in the operation process, but one man operation.It has simple in structure, and volume is little, and is in light weight, easy to operate, low price, and cost only needs 400 yuan, is easy to carry about with one the characteristics that are suitable for popularizing.Both be applicable to township hospital of basic unit, also be applicable to large hospital.

Claims (2)

1, implantation hole is bored in a kind of absence of tooth district that is used for, chargeable people's work post tooth machine of implantable artificial artificial tooth, comprise direct current generator (1), change-speed gearing group (2), shell (3), dentistry acute angle handpiece (4), lead (5), foot switch compositions such as (6), it is characterized in that:

A. direct current generator (1) change-speed gearing group (2) is sealed in the metal shell (3), and shell (3) head is dentistry acute angle handpiece (4) fixedly, and the rear portion connects lead (5), and the foot switch (6) of battery, control circuit board is housed in lead (5) other end connects;

B. the adhesive of anti-boiling water gluing is all used in the slit of all connecting portions in the shell (3), be full of in the shell high temperature resistant, butter does not trickle;

C. can directly utilize the oral cavity photo solidification machine, medical safe power supplys such as mouth illuminator also can connect battery and use.
