Abstract

The utility model discloses a gutta-percha point double-end burning removal apparatus, which solves the problem that a special apparatus for removing gutta-percha points does not exist in the prior art. The apparatus comprises a handle, wherein a transition section is arranged at each of two ends of the handle; a working section is arranged at the end of each of the two transition sections; a flat edge with an arc surface, suitable for front teeth and premolar teeth with small medullary cavities, is arranged at the end of one working section; and a gradually thinned hook suitable for molar teeth in the deep part of the oral cavity and having large medullary cavities, is arranged at the end of the other working section. The apparatus has the advantages that the working section is arranged at the end of each of the two ends of the handle, the flat edge with the arc surface is arranged at the end of one working section, the gradually thinned hook is arranged at the end of the other working section, and the two working sections have different purposes but can be alternately used, so that clinical application is facilitated; the cross sections of the working sections are rectangular, so that burning removal of the gutta-percha points is facilitated; after being heated with enough heat accumulation quantity, the apparatus can remove the bundled gutta-percha points conveniently and quickly; and the apparatus is durable, unlikely to break and suitable for wide clinical use.

Description

The gutta percha point both-end scalds except device

Technical field

This utility model belongs to a kind of medical apparatus and instruments, and the gutta percha point both-end of particularly removing gutta percha point after the root-canal filling treatment that a kind of dentistry is used scalds except device.

Background technology

The integrity of tooth has fundamental influence to masticatory function.After tooth generation dental caries are bad; if untimely treatment; the pathological changes will slowly develop constantly is difficult to stop automatically, also do not have self-healing property; tissue of tooth can slowly be etched; sick damage is ascending, from the superficial to the deep, involves dental pulp; the inflammation of secondary dental pulp, degeneration even necrosis, further then can cause periapical periodontitis.And this class pathological changes is difficult to find usually when tooth is not painful, in case find, has developed into pulpitis or apicitis mostly, at this moment, just needs the row root canal.Perfect root canal can make tooth be in health status in the use in future, inflammatory reactions such as pus fistula, pain no longer occur, and root canal completely and perfect root-canal filling is very important.In clinical, also need to take X-ray film after the root-canal filling and confirm whether its filling is dense pack, again the gutta percha point outside the root canal orifice is scalded after determining and remove.At present, also there is not a kind of apparatus that scalds except gutta percha point that is specifically designed in clinical, scald after doctor's probe burning commonly used heat and remove, but because probe is meticulous, with probe logarithm root gutta percha point scald except the time, normal because of heat distribute too fast can not be with the gutta percha point of bunchy boiling hot removing fully, so, heating back gutta percha point can be bonded on the probe, takes the root pipe out of thereby will not scald disconnected gutta percha point, causes the root-canal filling failure.In clinical, also have the doctor to adopt excavator spoon to scald and remove, but excavator spoon usually the phenomenon that the tip fractures can occur behind the sintering several, thereby can't continue to use.

Summary of the invention

The purpose of this utility model is to solve not to be specifically designed to the problem of scalding except the gutta percha point apparatus in the prior art, provides a kind of gutta percha point both-end of removing gutta percha point that is specifically designed to that is suitable for using in clinical to scald except device.

This utility model has a handle, the two ends of handle have a changeover portion respectively, in the end of two changeover portions an active section is arranged respectively, the end of an active section is the flat edge that has cambered surface, to be fit to less labial teeth and the premolars of pulp cavity, the end of another active section is the crotch of attenuation gradually, to be fit to be positioned at bigger the grinding one's teeth in sleep of pulp cavity in deep, oral cavity.

The cross section of described active section is rectangle, uses with convenient.

Advantage of the present utility model is:

1, at the two ends of handle an active section is set respectively, and the end of an active section is the flat edge that has cambered surface, and the end of another active section is the crotch of attenuation gradually, though the purposes of two active sections is not quite similar, but can also be used alternatingly, be convenient to clinical practice.

2, the cross section of active section is rectangle, be convenient to scald except gutta percha point, and amount of stored heat is enough after burning heat, can easily and efficiently the bunchy gutta percha point be scalded fully and remove.

3, durable in use, frangibility not, processing technique is easy, be conducive to produce, and cost is not high, is suitable for clinical being extensive use of.

The specific embodiment

As shown in drawings, this utility model has a handle 3, and the cross section of handle 3 is circular, and the surface crazing annular knurl of handle 3 is so that control; At the two ends of handle 3 changeover portion 2 is arranged respectively, two changeover portions 2 are taper shape, in the end of two changeover portions 2 active section 1, active section 4 are arranged respectively, the end of active section 1 is the flat edge 5 that has cambered surface, to be fit to less labial teeth and the premolars of pulp cavity, the end of active section 4 is the crotch 6 of attenuation gradually, to be fit to be positioned at bigger the grinding one's teeth in sleep of pulp cavity in deep, oral cavity; The cross section of described active section 1, active section 4 is rectangle, uses with convenient.

Claims

1. a gutta percha point both-end scalds except device, it is characterized in that, it has a handle, the two ends of handle have a changeover portion respectively, in the end of two changeover portions an active section is arranged respectively, the end of an active section is the flat edge that has cambered surface, and the end of another active section is the crotch of attenuation gradually.

2. gutta percha point both-end according to claim 1 scalds except device, it is characterized in that the cross section of described active section is rectangle.
