Abstract

A kind of tooth-implanting screw hole temporarily seals object cleanout tool, is related to medical equipment technical field, and the solution is to plant dental restortion and maintenance.The tool includes knife bar, and is fixed on the handle of knife bar upper end, is fixed on the helical form cutter head of the upper thick lower point of knife bar lower end；The knife bar is straight-bar, being equipped on knife bar can be along the locator that knife bar moves up and down, the locator is rim of a cup cup body directed downwardly, the knife bar passes through locator from top to bottom, and locator can slide down to the lower edge of locator and flush with the lower end of cutter head, so that in the inner cavity of cutter head retraction locator.Tool provided by the utility model, for removing the temporary envelope object in tooth-implanting screw hole.

Description

Tooth-implanting screw hole temporarily seals object cleanout tool

Technical field

The utility model relates to medical equipment technologies, and the skill of object cleanout tool is temporarily sealed more particularly to a kind of tooth-implanting screw hole Art.

Background technique

Tooth-implanting is made of two parts of planting body and corona, is one of recovery technique of absence of tooth, plantation therein Root of the tooth is served as in body implantation alveolar bone, corona is fixed by screws on planting body.

The tooth-implanting of screw retained needs to be closed central screw hole with stopping dressing after the installation is completed, plants the reparation of corona With the center screw for needing repeatedly to turn plantation corona in maintenance process, the stopping dressing of central screw hole needs filling out back and forth Envelope is taken out, and the stopping dressing of central screw hole has two layers, and one layer close to central screw is relatively soft, and outer layer is then relatively hard.

Existing tooth-implanting center screw hole stopping dressing removal method is all to abrade central screw hole with high speed handpiece by doctor The relatively hard filler of outer layer, complexed metal dig spoon and dig out stopping dressing from central screw hole, and this mode of operation is very Inconvenience, the operating time is relatively long, and is easy to cause to damage to screw and screw hole, to influence subsequent operations, or even not Central screw can be taken out.

Utility model content

For above-mentioned defect existing in the prior art, the technical problem to be solved by the utility model is to provide a kind of behaviour Make it is convenient, the operating time can be saved, and can effectively avoid damage to screw, the tooth-implanting screw hole of screw hole temporarily seals object cleanout tool.

In order to solve the above-mentioned technical problem, a kind of tooth-implanting screw hole provided by the utility model temporarily seals object cleanout tool, It is characterized by comprising knife bars, and are fixed on the handle of knife bar upper end, are fixed on the helical form knife of the upper thick lower point of knife bar lower end Head；

The knife bar is straight-bar, and being equipped on knife bar can be one glass along the locator that knife bar moves up and down, the locator The cup body of mouth down, the knife bar pass through locator from top to bottom, and locator can slide down to the lower edge of locator with The lower end of cutter head flushes, so that in the inner cavity of cutter head retraction locator.

Further, the outer wall lower part of the locator is formed with the flange projected radially outwardly.

Further, the locator is threadedly engaged with knife bar.

Further, an operating stick is fixed on the outer wall of the locator.

Tooth-implanting screw hole provided by the utility model temporarily seals object cleanout tool, and it is precisely fixed to be implemented by locator to cutter head Position, is taken out after being hooked the temporary envelope object in the screw hole of tooth-implanting center using spiral helicine cutter head, and in cutter head drilling, positioning Device can ensure that drilling stability, it is ensured that drilling direction does not deviate by, and operation is very easy, can save the operating time, can effectively keep away Exempt to damage screw, screw hole.

Detailed description of the invention

Fig. 1 is that the tooth-implanting screw hole of the utility model embodiment temporarily seals the structural schematic diagram of object cleanout tool；

Fig. 2 is that the tooth-implanting screw hole of the utility model embodiment temporarily seals the use schematic diagram of object cleanout tool.

Specific embodiment

The embodiments of the present invention are described in further detail below in conjunction with Detailed description of the invention, but the present embodiment and are not had to In limitation the utility model, all similar structures and its similar variation using the utility model should all be included in the utility model Protection scope, the pause mark in the utility model indicates the relationship of sum, and the English alphabet in the utility model is case sensitive.

As shown in Figure 1, a kind of tooth-implanting screw hole provided by the utility model embodiment temporarily seals object cleanout tool, feature It is: including knife bar 1, and is fixed on the handle 2 of knife bar upper end, is fixed on the helical form cutter head 3 of the upper thick lower point of knife bar lower end；

The knife bar 1 is straight-bar, and being equipped on knife bar 1 can be along the locator 4 that knife bar moves up and down, the locator 4 One rim of a cup cup body directed downwardly, the knife bar 1 passes through locator 4 from top to bottom, and locator 4 can slide down to locator 4 Lower edge flushed with the lower end of cutter head 3 so that the outer wall lower part of locator 4 is formed with diameter in the inner cavity of cutter head retraction locator 4 To outwardly projecting flange 41.

In the utility model embodiment, the locator 4 is threadedly engaged with knife bar 1, is fixed with one on the outer wall of locator 4 Operating stick 5.

The utility model embodiment is for removing the temporary envelope object in tooth-implanting screw hole in department of stomatology operation, usage mode is such as Under:

As shown in Fig. 2, the outer layer that the central screw hole stopping dressing for striking off plantation corona 6 in advance is harder, then by locator 4 It is displaced downwardly to the inner cavity of 3 retraction locator 4 of cutter head, the lower edge of locator 4 is resisted plantation corona 6 by another hand-held bar 5, this When struck off due to the harder outer layer of stopping dressing, the lower edge of locator 4 can slightly be caught in the central screw hole of plantation corona 6, fixed The flange 41 of position 4 outer wall lower part of device can then resist the upper surface of plantation corona 6, it is too deep be avoided that 4 lower edge of locator is caught in, then The other hand rotational handle 2 is used again, to drive cutter head 3 to pierce stopping dressing, so that cutter head 3 hooks temporary envelope by helical structure Then cutter head 3 is extracted outward, can take out stopping dressing by material.

In the utility model embodiment, since locator 4 and knife bar 1 are threadedly engaged, it can improve and bore when cutter head is crept into Into stability, it is ensured that drilling direction does not deviate by, and in the utility model other embodiments, locator and knife bar can also be using cunnings Dynamic fit system, also can easily and efficiently take out stopping dressing using sliding matching mode, also can effectively avoid damage to screw, Screw hole, but cutter head drilling stability does not have thread fiting mode good.

In the utility model embodiment, due to being fixed with operating stick 5 on the outer wall of locator 4, doctor can pass through operation Locator is easily resisted plantation corona by bar, in the utility model other embodiments, can not also be set in the outer wall of locator Operating stick is set, can similarly locator be resisted plantation corona by being not provided with operating stick, but operation ease is with respect to meeting slightly lower one A bit.
