Abstract

The utility model relates to a medical treatment apparatus, in particular to a measuring device for the working length of a base tube, which is used in cooperation with a magnifying apparatus of the base tube. The utility model comprises a scale plate, a ring sleeve and a cursor hole. The ring sleeve can make the apparatus worn on the hand of an operator conveniently; the cursor hole is used for positioning. The rubber superscript in the magnifying apparatus of the base tube can measure the working length and the material-filling length accurately. So the utility model can realize better curing effects.

Description

Measuring device

Technical field

This utility model relates to the measurement root canal working length of medical instruments field department of stomatology special use and a kind of measuring device of filler length.

Background technology

At present, the department of stomatology, Hospital doctor carries out root canal to ill tooth, usually employing progressively retreats method, balance force method or crown root carry out root canal preparation to technology such as no pressure, which kind of method no matter, must strictly control expansion instrument (as enlarging pin, root canal file, the G brill) measurement length is consistent with root canal working length, when now general department of stomatology, Hospital doctor treats, measuring expansion instrument length and measuring root canal filling material length is to adopt general scale steel ruler or mould chi, from the treatment dish, take up and down, frequently measure in the clinical manipulation of adjustment extremely inconvenient, also unhygienic at need.

Summary of the invention

In order to solve the deficiencies in the prior art part in this field, this utility model provides a kind of measurement root canal working length and root canal filling material measurement of length device, and easy operating carries, and makes things convenient for root pipe expansion instrument to measure and adjust.

The invention technical scheme that this utility model solves its technical problem is described as follows: it mainly includes graduated tile, finger ring cover, vernier hole, the positive quarter of the rectangle graduated tile of golden section put scale, the back side of graduated tile connects the finger ring cover, and its designing technique characteristics are that the graduated scale starting point at graduated tile is provided with the vernier hole.

The beneficial effects of the utility model are that the finger ring cover can make this device be worn on doctor's the left hand middle finger or the third finger, be convenient to measure the length of the root pipe expansion instrument that the right hand holds, the rubber that the vernier borehole jack connects root pipe expansion instrument ends mark, the length of the correct active length of location survey root pipe reality and preparation filler, make the length of filler consistent, reach ideal therapeutic effect with the active length of root pipe.

The drawing explanation

Fig. 1 is this utility model topology view.

Fig. 2 is the view that has transparent sheath.

1-finger ring cover, the 2-graduated tile, the 3-bonnet lock hole, 4-vernier hole, the transparent separation sleeve of 5-, 6-leads to button hole.

The specific embodiment

Now, with the record of embodiment, details are as follows to technology contents of the present utility model with reference to the accompanying drawings.

Graduated tile of the present utility model 2 positive both sides are carved and are equipped with the graduated scale of measuring length, and unit length is got mm, measure to be accurate to 0.5mm, according to clinical use scale to carve to put length be 3cm.Starting point (zero point) at scale is provided with vernier hole 4, and the rubber that is used to locate root pipe expansion instrument ends mark, and there are two bonnet lock holes 3 at the back side of graduated tile 2, connects the hasp that finger ring overlaps 1 two, consults Fig. 1.Finger ring cover 1 can also be processed into the structure of two bent arc shapes by ductile metal, according to user finger thickness scalable size.

In order to keep this utility model to use health, prevent the cross infection between the patient, for graduated tile 2 designs are supporting transparent separation sleeve 5 is arranged, two logical button holes 6 that mate with bonnet lock hole are offered at these separation sleeve 5 back sides, just, back of the body west offers a mating holes that leads to vernier hole 4, consults Fig. 2.

During clinical use, the root pipe expansion instrument that the doctor holds the right hand (enlarge pin, root canal file, G bores) the measurement root canal working length, rubber is only marked sleeve leftward in the vernier hole 4 on the graduated tile 2 on the middle finger, just can read and enlarge the pin apparatus and record disease pulp canal work correct length.At preparation filler such as gutta percha point, can be used to measure the length of reading gutta percha point, it is consistent with the active length of root pipe better to grasp packing material.

Claims

1, a kind of measuring device, it includes graduated tile, the finger ring cover, vernier hole, the graduated tile back side connect the finger ring cover, the positive quarter put scale.The graduated scale starting point (zero point) that it is characterized in that graduated tile (2) has vernier hole (4).

2, measuring device according to claim 1 is characterized in that graduated tile (2) is equipped with transparent separation sleeve (5).
