Description

[Detailed Description of the Invention] The present invention relates to a dental permanent fixture with a manual pump used for cleaning cutting powder, dirt, etc. in the enlarged root canal of a tooth to be treated.

Conventionally, when cleaning cutting powder, dirt, etc. in the enlarged root canal of a tooth to be treated, cleaning was done by permanently attaching something similar to a syringe needle to a glass syringe barrel.

However, in this conventional permanent method, the pressure is weak and the amount is small, so there is a drawback that cutting powder, dirt, etc. in the root canal cannot be sufficiently cleaned.

The purpose of the present invention is to eliminate the above-mentioned deficiencies of the conventional technology. A cylinder part 3 is formed in the cylinder part 2, and a piston rod 5 whose base end is connected to a lever 4 is slidably fitted into the cylinder part 3, and the cylinder part 3 and the compression chamber 6 are connected to each other by a check valve. The fluid pressure in the compression chamber 6 is increased and maintained through the communication hole 8 provided with the cylinder 7, and the cylinder part 3 and the container 1 are communicated through the communication hole 9, thereby reducing the internal pressure of the container 1. The cylinder part 3 and the suction pipe 10 disposed inside the container 1 are communicated with each other through a suction hole 12 provided with a check valve 11, thereby controlling the pressure inside the compression chamber 6 and the container. The pressure inside the compression chamber 6 is increased, and the nozzle 13 is attached to the compression chamber 6.

Next, the configuration of the present invention will be described in detail below based on an example of implementation shown in the drawings.

FIG. 1 is a perspective view showing a dental permanent fixture with a manual pump, which is an example of the implementation of the present invention, and FIG. 2 is a vertical cross-sectional view showing a part of the same dental permanent pump with a manual pump. , 1 is a container containing water or a chemical solution therein, 2 is a compression chamber main body, 3 is a cylinder part formed in the compression chamber main body 2, 4 is a lever whose upper end is pivotally connected to the compression chamber main body 2,
5 is a slidable piston rod disposed within the cylinder part 3 and whose base end is pivotally connected to the lever 4; 6 is a compression chamber formed in the main body 2; 7 is a compression chamber that is connected to the cylinder part 3; This is a check valve provided in the communication hole 8 that communicates with the chamber 6 to prevent the water or chemical liquid in the compression chamber 6 from flowing backwards.In the embodiment, as shown in FIG. A protruding tube 7a with the rear end of 3 extended outward.
A ball a is loosely fitted inside to form a check valve.

b is a stopper. Reference numeral 8 denotes a communication hole consisting of a pore that communicates between the cylinder part 3 and the compression chamber 6, 9 a communication hole that communicates the cylinder part 3 and the container 1, 10 a suction pipe arranged in the container 1, and 11 is a check valve provided in the suction hole 12, into which a ball a is loosely fitted, as shown in FIGS. 3 and 4.

b is a stopper. 12 is cylinder part 3 and container 1
This is a suction hole that communicates with the suction pipe 10 disposed inside, and in the embodiment, as shown in FIG. 2, it is connected to the suction pipe 10 via a connecting pipe 14.

13 is a water inlet 15 formed in the compression chamber 6 with a nozzle.
It is attached to.

16 in the figure is a piston installed at the tip of the piston rod 5, and 17 is a spring attached to the cylinder part 3. When the lever 4 is loosened, the piston 16 is moved by its elastic force.
This was done so that it would recede.

18 is a lid for attaching the compression chamber main body 2 to the container 1.

Therefore, when using the dental permanent machine with a manual pump of the present invention to wash away cutting powder and dirt generated from drilling and grinding work in the root canal of the tooth to be treated, first use a container containing water or a chemical solution.
After attaching the compression chamber body 2 to the body, grasp it with one hand, push and spread the patient's oral cavity with the other hand, insert the permanent nozzle 13 of the present invention into the oral cavity, and repeat the lever operation.

Then, first, the piston rod 5 enters the cylinder part 3, and the piston 16 of the rod 5 pushes out the air in the cylinder part 3 through the communication hole 8 into the compression chamber 6. It enters the container 1 through the container 1, presses the water and chemical solution in the container 1, and the water and chemical solution enters the cylinder part 3 through the suction pipe 10, the connecting pipe 14, and the suction hole 12, and then The water or chemical liquid that has entered the cylinder part 3 is pressed by the piston 16 and is forced into the compression chamber 6, and the forced water or chemical liquid is ejected from the nozzle 13 through the water inlet 15.

Then, the lever operation is repeated, and when the pressure inside the container 1 rises and a constant pressure water stream continues to be ejected from the nozzle 13 even after the lever operation is stopped, the lever operation is stopped and the nozzle The tip of No. 13 is inserted into the root canal, and cutting powder, dirt, etc. in the root canal are completely washed away by this continuous water flow at a constant pressure.

The dental permanent device with a manual pump of the present invention is constructed as described above, so that by simply pressurizing the inside of the container with a lever operation, pressurized water can be continuously ejected from the nozzle. It has the outstanding effect of being able to very easily and reliably clean cutting powder, dirt, etc. from the narrow and complicatedly deformed root canal.
