Embodiment 1

[0035] A telescopic root canal file comprises a handle 1, a neck 2 and a blade 3 which are sequentially connected, and the handle 1 is a telescopic handle.

[0036] In this embodiment, by setting the handle 1 as a retractable handle, the length of the handle 1 can be adjusted, and when the medical personnel prepare the root canal of the patient's teeth, the length of the handle 1 can be selected according to the specific conditions of the patient's oral cavity opening and closing. It not only adapts to the opening and closing degree of the patient's mouth, but also adapts to the operating hand of the medical staff, so that the medical staff can prepare the root canal. In the middle of the root canal preparation, when the cutting edge of the root canal has entered the root canal, the handle 1 can be extended to facilitate the medical staff to pull or rotate the root canal file, which greatly facilitates the medical staff to operate the root canal file.

Embodiment 2

[0038] On the basis of Embodiment 1, the telescopic handle 1 includes a fixed tube 11 and a telescopic column 12, the fixed tube 11 is fixedly connected to the neck 2, and the front end of the inner wall of the fixed tube 11 is provided with a semicircular hole 13 along the axial direction of the fixed tube 11 , the front end of the inner side wall of the fixed pipe 11 is also provided with a second positioning hole 14, the second positioning hole 14 is fixedly connected with a plastic meson 15, and the telescopic column 12 is sleeved in the plastic meson 15 and can move along the axis of the fixed cylinder 11, The rear end of the outer side wall of the telescopic column 12 is provided with a spring protrusion 16, and the spring protrusion 16 is compatible with the semicircular hole 13. The rear end of the outer side wall of the telescopic column 12 is provided with a first positioning hole 17, and the first positioning hole 17 A wear-resistant sheet 18 is arranged inside, and ...

Embodiment 3

[0041] On the basis of Embodiment 2, the spring protruding device 16 includes a hole 161 provided on the side wall of the telescopic column 12, a small ball 162 is arranged in the hole 161, and the semicircular hole 13 and the hole 161 are compatible with the small ball 162. A spring 163 is also arranged in the hole 161 , the bottom end of the spring 163 is connected with the bottom wall of the hole 161 , and the top end of the spring 163 is connected with the small ball 162 .

[0042] Shown in this embodiment is the concrete structure of a kind of spring protruding device, and this protruding device structure is simple and reliable, and ball 162 is close to the inner side wall of fixed tube 11 under the effect of spring 163, when ball 162 moves to semicircular hole At 13 o'clock, the bead 162 directly enters the semicircular hole 13, and now the bead 162 and the semicircular hole 13 directly lock the telescopic column 12 and the fixed tube 11, and the handle 1 is no longer ext...

Abstract

The invention discloses a telescopic root canal file, and aims at solving the problems that in the prior art, the length of the root canal file is shorter, so that the operation of medical personnel is influenced. The telescopic root canal file comprises a handle, a neck part and a blade part in sequential connection, wherein the handle is a telescopic handle. The telescopic root canal file is used for root canal preparation.

Description

technical field [0001] The invention belongs to a dental medical instrument for root canal treatment of affected teeth, in particular to a root canal file for treating molar root canals. Background technique [0002] Pulp disease and periapical disease are common diseases in the Department of Stomatology. Preserving the patient's teeth and pulp is the purpose of modern stomatology, and root canal therapy is currently the most common and effective treatment. The principle of root canal treatment is to remove most of the infected substances in the root canal through mechanical and chemical methods, and to prevent the occurrence of periapical lesions or promote the healing of periapical lesions that have occurred by filling the root canal and sealing the crown. [0003] Root canal treatment generally involves the following steps: [0004] 1. Root canal preparation: open the pulp, thoroughly clear the necrotic pulp tissue, measure the length of the root canal, and expand the ro...
