The air pump type automatic tooth extraction device has the advantages of being not high in technical requirement for operators and convenient to operate and achieving operation instantly and being small in trauma.

Description

The air-pump type device of automatically having tooth pulled out

Technical field

This utility model relates to one in medical science dental field exodontia instrument, specifically relates to a kind of air-pump type device of automatically having tooth pulled out.

Background technology

At modern medicine dental field, exodontia instrument is mainly caliper, people are for good operability, convenient and swift in the time having tooth pulled out, existing equipment has been carried out to a large amount of improvement or combination, totally do not depart from manually-operated limitation, greatly challenge operator's technical merit and practical experience, the injury that cannot avoid anthropic factor to produce.

Utility model content

The purpose of this utility model is exactly the deficiency existing for existing technology, and a kind of anthropic factor, easy to operate air-pump type device of automatically having tooth pulled out of eliminating is provided.

Technical scheme: comprise oval ring body, through hole is axially set on vesica piscis body wall, in through hole, disclose into tooth hook nail, tooth hook nail top is fixed by pin at oval ring body end face, pin is embedded in the cotter way of bore periphery, vesica piscis is external by the sheathed sliding sleeve of keyway, and sliding sleeve lateral wall periphery arranges anodal magnet ring; Sliding sleeve is sheathed gas cap from top, and gas cap bottom periphery arranges negative pole magnet ring, and gas cap top connects air pump by trachea, and air pressure regulator is set on air pump.

Beneficial effect: this device is technical less demanding to operator, easy to operate, the size dimension of extracting tooth by the distance adjustment between through hole on oval ring body, tooth hook nail inwardly hooks tooth, and sliding sleeve lateral wall periphery arranges anodal magnet ring and with gas cap bottom periphery, negative pole magnet ring is set and inhales mutually, when air pump work, pin gas cap downwards, oval ring body under suction, by and sliding sleeve between keyway on promote out tooth, instantaneous complete operation is traumatic little.

Brief description of the drawings

Accompanying drawing 1 is the structural representation of the present embodiment; Accompanying drawing 2 is structural representations of the present embodiment gas cap part.

Detailed description of the invention

With reference to accompanying drawing 1,2, the present embodiment mainly comprises oval ring body 1, on oval ring body 1 wall, through hole 2 is axially set, 2-4 tooth hook nail 3 of the interior insertion of through hole 2, tooth hook nail 3 tops are fixed by pin 4 at oval ring body 1 end face, pin 4 is embedded in the cotter way of through hole 2 peripheries, and oval ring body 1 is outer by the sheathed sliding sleeve 9 of keyway 10, and sliding sleeve 9 lateral wall peripheries arrange anodal magnet ring 5; Sliding sleeve 9 is sheathed gas cap 6 from top, and gas cap 6 bottom periphery arrange negative pole magnet ring 7, and gas cap 6 tops connect air pump 8 by trachea, on air pump 8, air pressure regulator are set.

In concrete application, can hang and close with tooth hook nail 3 in the boring of tooth outside in advance, tooth hook nail 3 tops insert that through hole 2 inner peg 4 are axially set on oval ring body 1 wall is fixing, and pin 4 is embedded in the cotter way of through hole 2 peripheries, prevents that tooth hook nail from rotating.
