Abstract

The utility model relates to a dentistry tool for receiving saliva, particularly a saliva isolating rack for removing saliva in dentistry. A fixing clamp of the utility model is divided into a fixing clamping end and a pulling end, and a middle part thereof is movably connected with a U-shaped supporting rack; the pulling end is movably connected with a draw rod. When the draw rod is pulled, the fixed end of the fixing clamp is displaced under the action of a connection point of the U-shaped supporting rack; a cotton roll for isolating saliva is fixedly clamped on the two sides of a sick tooth to achieve the purpose of wetness isolation. Therefore, the utility model has the advantage of simple operation, and can be used on a sick tooth in any part.

Description

The saliva isolating frame

This utility model relates to the dental appliance that is used to receive saliva, especially a kind of saliva isolating frame that is used for dentistry removal saliva.

When doing root canal or dental caries filling treatment, should separate suffering from tooth and oral environment, enter the art district with the antibacterial that stops saliva and include, prevent moisture effects filler performance simultaneously and hinder material and the driving fit of suffering from tooth, therefore suffer from tooth and should fully isolate with saliva.The present partition method that adopts: a kind of is rubber dam.Promptly use a rubber membrane that elasticity is good, isolate the position of tooth as required, on film, use the card punch eyeletting, utilize rubber elasticity, magnify hole with instrument and be inserted in the trouble tooth, the resilience of rubber nature and lock ring neck portion.Have the trouble corona only and expose outside the barrier, itself and oral environment are isolated, but the operation of this method is more loaded down with trivial details; Another kind is to adopt lap to isolate to suffer from tooth, lap is placed suffer from tooth cheek, lip vestibule place and tongue side mouth bottom, suffers from periodontal saliva with absorption, thereby reaches every wet purpose.For preventing that lap from moving, and used the lap depressor, it comprise pull bar, fixed bar and with the link of lap pressure head logotype, but this lap depressor can only be used for lower jaw.

The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of easy and simple to handle, can be used for the saliva isolating frame that tooth is suffered from any position.

For achieving the above object, this utility model comprises pull bar, fixation clamp, described fixation clamp is half-moon-shaped, two tops of U type support flexibly connect with the middle part of described fixation clamp respectively, the both ends of fixation clamp are respectively solid folder end and tractive end, and the tractive end of described pull bar one end and described fixation clamp flexibly connects, and the other end is shaped on screw thread, the end of thread of pull bar stretches out through the stretch hole of U type support bottom, and coupling has nut.

Fixation clamp of the present utility model is divided into solid folder end and tractive end, position, intermediate portion and U type support flexibly connect, tractive end and pull bar flexibly connect, the pulling pull bar, the stiff end of fixation clamp with the effect of U type support junction point under be subjected to displacement, be sandwiched in admittedly and suffer from the tooth both sides isolating lap that saliva uses, reach every wet purpose, so the utlity model has advantages of simple operation, and can be used on the trouble tooth at any position.

Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.

Accompanying drawing is a kind of structural representation of the present utility model, also is the sketch map of a kind of embodiment.

As shown in drawings, fixation clamp 1 usefulness white alloy plate is made into blunt half-moon-shaped of edge circle, half-moon-shaped fixation clamp 1 is divided into fixation clamp end 2 and tractive end 3 respectively, support 4 usefulness bidery metals are made " U " type, two tops of " U " type support 4 flexibly connect with the middle part of pin and fixation clamp 1 respectively, and an end of pull bar 5 flexibly connects with the tractive end 3 of pin and fixation clamp 1, and other end car is shaped on screw thread, the end of thread of pull bar 5 stretches out through the stretch hole 6 of " U " type support 4 bottoms, and with the screw thread coupling nut 7 is arranged.

During use, to be placed in every the lap of wet usefulness and suffer from the tooth both sides, fastening nut 7, make pull bar 5 and the tractive end 3 of the folder 1 that is strained and fixed, fixation clamp 1 rotates around the pin of " U " type support 4 and its flexible connection, thereby makes the stiff end 2 of fixation clamp 1 clamp laps under the effect of pull bar 5, isolate saliva, reach every wet purpose.

Claims

1, a kind of saliva isolating frame, comprise pull bar, fixation clamp, it is characterized in that: described fixation clamp is half-moon-shaped, two tops of U type support flexibly connect with the middle part of described fixation clamp respectively, the both ends of fixation clamp are respectively solid folder end and tractive end, and the tractive end of described pull bar one end and described fixation clamp flexibly connects, and the other end is shaped on screw thread, the end of thread of pull bar stretches out through the stretch hole of U type support bottom, and coupling has nut.
