Abstract

The utility model patent is invented to provide a convenient tool using an annular sleeve when slit expanding is performed on to-be-straightened teeth for dentists, so that the work quality of the dentists is better improved, and the pain of dental patients is reduced. The integral structure of a slit expanding device for the teeth consists of two parts: an outside caliper and an inside caliper, wherein the exterior of the jaw of the outside caliper is provided with a bayonet; an inside caliper fixing clip channel is formed in the middle part of the transverse caliper body of the outside caliper; a spring fixing clip is arranged at the interior joint of a handle and the transverse caliper body of the outside caliper; the exterior of the jaw of the inside caliper is provided with a bayonet; a spring fixing clip is arranged outside the joint of the transverse caliper body and an inside handle of the inside caliper.

Description

Tooth expands seam device

Technical field:

This utility model patent is to be oral cavity straightening of teeth specially, expands the designed a kind of apparatus in gap, and particularly a kind of tooth expands seam device.

Background technology:

The present medical domain of China is very flourishing, various medical science apparatus are comparatively complete, but instrument used some deficiency also in straightening of teeth field, oral cavity, particularly the chamber equipment that tooth expands seam use that straightens one's teeth is just seen and is only had spring cassette and ring-like shell type at present, while using spring cassette to expand seam to tooth, only from the root of two teeth spaces, disclose and drag inward, ring-like shell type does not in use have applicable use instrument, and dentist only has with other hook tool replacement pulling, causes suffering very easily to odontopathy patient.

Summary of the invention:

The object of this utility model patented invention, be for dentists provide a kind of use ring-like cover while expanding seam for straightening of teeth just use instrument, to better improve dentists' work quality, reduce odontopathy patient's misery.

Technical scheme:

This utility model patent tooth expands seam device, overall structure by: bow compass and inside plain calipers two parts form; Wherein: the jaw extroversion of bow compass has a bayonet socket, there is an inside plain calipers fixed card road at horizontal vice body middle part, and there is a spring fixed clip handle of bow compass and junction, horizontal vice body the inside; The jaw outside of inside plain calipers is provided with a bayonet socket, and the outside that the horizontal vice body of inside plain calipers is combined with Internal handle is provided with a spring fixed card.

Beneficial effect:

The beneficial effect of this utility model patent is, while providing a kind of straightening of teeth to expand seam for dentists, the ring-like cover that uses just use instrument, to improve dentists' work quality, reduce odontopathy patient's misery, device is stitched in tooth expansion, small and exquisite easy-to-use, time saving and energy saving.

Accompanying drawing explanation:

Fig. 1 is that tooth expands seam device overall diagram.

Fig. 2 is that tooth expands seam device ectosome figure.

Fig. 3 is that tooth expands seam device endosome figure.

In Fig. 1,1 is bow compass handle, 2 inside plain calipers handles, 3 inside plain calipers fixed card roads, 4 inside plain calipers bayonet sockets, 5 bow compass bayonet sockets, 6 bow compasses expansion seam cuttves, 7 steady pins, 8 springs; In Fig. 2,1 is bow compass handle, 3 inside plain calipers fixed card roads, 5 bow compass bayonet sockets, 6 bow compasses expansion seam cuttves, 7 steady pins, 9 bow compass handle spring fixed clips; 2 inside plain calipers handles, 4 inside plain calipers bayonet sockets, 8 springs, 10 Internal handle spring fixed cards, 11 inside plain calipers sliding trays in Fig. 3.

The specific embodiment:

When inside plain calipers handle (2) is installed, by inside plain calipers fixed card road (3), fixing with steady pin (7), one end of spring (8) engages mutually with bow compass handle spring fixed clip (9), the other end engages mutually with Internal handle spring fixed card (10), during use, as long as expansion is stitched, leather sheath ring is stuck in inside plain calipers bayonet socket (4) and bow compass bayonet socket (5) is located, simultaneously with finger pinching bow compass handle (1) and inside plain calipers handle (2).
