Description

A file clamp for root canal length measuring apparatu

Technical Field

The utility model belongs to the oral medical instrument field especially relates to a file clamp for root canal length measuring apparatu.

Background

The root canal measuring instrument is a medical instrument used by dentists for root canal treatment, which is called root measuring instrument for short, and the root canal treatment is a treatment process aiming at tooth, dental pulp and apical lesion. Root canal therapy is a treatment method for preventing periapical lesions or promoting healing of periapical lesions by removing necrotic material from the root canal, appropriately disinfecting, and filling the root canal to remove adverse irritation of the contents of the root canal to the tissues around the apical tip. Root canal measuring apparatu is through measuring tooth apical length, helps the dentist to accomplish root canal treatment, through the guide of root measuring appearance, makes the doctor have accurate assurance to root canal length to accomplish perfect filling.

Root survey appearance when using, when the one end of root canal needle need be put through with root survey appearance line, just press from both sides the file clamp of one of serving of connecting wire in the upper end of root canal needle tightly, the crochet hook that has the file clamp now is made by all with a sheet steel, the crochet hook is made to sheet steel needs certain thickness and width, a problem brought is that the head size of crochet hook is great, the operation of being not convenient for observe in the confined space in oral cavity, be connected occasionally easily blocked when operation and tiny root canal needle, in addition, the crochet hook is made to sheet steel needs to pass through mould stamping forming, material consumption is big, the cost of manufacture is high.

Therefore, it is necessary to develop a file clip for root canal length measuring instrument.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a file presss from both sides for root canal length measuring apparatu to solve prior art's above-mentioned problem, take following scheme.

The utility model provides a file presss from both sides for root canal length measuring apparatu, includes file clamp cap, file clamp cover, spring and steel wire hook, the file clamp cap is the open tubular structure of one end, the file clamp cover is hollow tubular structure, the one end of file clamp cap stretches into in the file clamp cover, the spring sets up in the file clamp cap, the both ends of spring respectively with the file clamp cap contacts with file clamp cover, the steel wire hook is located the inside of file clamp cover, the one end of steel wire hook by the one end that the file pressed from both sides the cover is worn out and is hook-like, the steel wire hook is made by cylindrical steel wire.

Further, the angle of the hook-shaped bending of one end of the steel wire hook is not more than 90 degrees.

Furthermore, the shape of one end of the steel wire hook is a bent frame structure, the inside of the frame structure is a bent question mark shape, the frame structure of the steel wire hook is embedded in the spring, and the diameter of the steel wire hook is not more than 0.8 mm.

Further, a wire introduced through an opening in the cylindrical side or top surface of the rasping cap is connected to the wire hook.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the file clip of the utility model is made of fine steel wires, which is convenient for the doctor to observe and operate.

2. The utility model discloses a file presss from both sides, replaces the steel sheet hook that prior art used with the steel wire hook, need not open the mould during preparation, and material utilization is high, has practiced thrift the cost greatly.

Detailed Description

In order to make the technical solution of the present invention better understood, the technical solution of the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts shall belong to the protection scope of the present invention.

As shown in figures 1 to 3.

The utility model provides a file clip for a root canal length measuring instrument, which comprises a file clip cap 1, a file clip cover 2, a spring 3 and a steel wire hook 4, wherein one end of the file clip cover 2 is big and the other end is small, and the middle part is hollow; one end of the cylindrical file clamp cap 1 is open, the open end of the file clamp cap 1 extends into the big head end of the file clamp sleeve 2, and the side surface of the end, exposed out of the file clamp cap 1, of the file clamp cap 1 is provided with an opening power supply wire to penetrate through; the spring 3 is positioned in the file cap 1, one end of the spring 1 props against the file cap 1, and the other end of the spring 1 props against the file jacket 2; the steel wire hook 4 is made of a cylindrical steel wire with the diameter not larger than 0.8mm, the steel wire hook 4 is positioned in the axial center part of the file jacket 2, one end of the steel wire hook 4 penetrates out of one end of the file jacket 2 and is bent into a hook with the angle not larger than 90 degrees, the other end of the steel wire hook 4 is bent into an outer square frame, the shape of the inner bend is similar to a question mark in a punctuation mark, the question mark end of the steel wire hook 4 is welded with the penetrated electric wire, and the square frame of the steel wire hook 4 is embedded in the spring 3.

When the dental root length measuring device is used, when a doctor needs to measure the length of a dental root, one end of the file clamp cap 1, which is exposed outside, is pressed down by a finger, the file clamp cap 1 pushes the spring 3 to drive the steel wire hook 4 to move, so that the hook at one end of the steel wire hook 4 extends out, when the hook hooks one end of a root canal needle or a probe, the finger is loosened, and the steel wire hook 4 is driven by the elasticity of the spring 3 to clamp the root canal needle or the probe tightly.

Utilize technical scheme, or technical personnel in the field are in the utility model discloses under technical scheme's the inspiration, design similar technical scheme, and reach above-mentioned technological effect, all fall into the utility model discloses a protection scope.
