Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, and specifically, it is an oral root canal irrigator. Background Art

[0002] Root canal treatment is the most commonly used method for treating dental diseases and is the most commonly used and effective treatment method for pulp diseases and periapical diseases internationally. The principle of root canal treatment is to remove most of the infective substances in the root canal through mechanical and chemical methods, and prevent the occurrence of periapical lesions or promote the healing of existing periapical lesions by filling the root canal and sealing the crown. In the process of root canal treatment, effective root canal irrigation is the key to treatment.

[0003] In the prior art, a Chinese patent with the authorization announcement number CN215688586U is provided. This patent discloses a dental root canal cleaning device for children, including an electric syringe, a solvent bottle, and a needle.

[0004] However, since the syringe in the prior art forms a single flushing channel, generally two flushing liquids need to be used alternately during oral root canal flushing, and at least two irrigators are required, resulting in waste of medical resources and increased time cost of medical staff operation.

[0022] Next, in combination with the attached drawings in the embodiments of the present utility model Figure 1-2 , the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0023] Problems existing in the prior art are:

[0024] 1. Existing oral root canal irrigators are disposable metal blunt-tip irrigation needles with a needle irrigation diameter of 0.3 - 0.4 mm. For young children, such irrigation needles are likely to cause fear in children, and there is a risk of instrument separation when the needle is bent. In addition, since the needle is a plug-in type needle, when the resistance is large, the needle and the syringe barrel are likely to separate, resulting in the splashing of the irrigation fluid and increasing the treatment risk;

[0025] 2. Oral root canal irrigation is generally carried out by alternately flushing with two kinds of irrigation fluids, and at least two irrigators are required. In addition, when the irrigation fluid is insufficient, the needle plug needs to be removed for adding fluid or a new irrigator needs to be used again, resulting in a waste of medical resources and increasing the time cost of medical staff operation.

[0026] To solve the above problems, as Figure 1 shown, a liquid-adding oral root canal irrigator is proposed, including:

[0027] Two syringe bodies arranged side by side, each syringe body includes a barrel 11 and a piston rod 2. The inner cavity of the barrel 11 is set as a strip-shaped flushing channel 111 extending along the flushing direction. The piston part of the piston rod 2 is slidably inserted into the flushing channel 111, and the end of the rod-shaped part of the piston rod 2 is outside the barrel 11;

[0028] A hollow intermediate connection part 12, the intermediate connection part 12 is fixedly connected to the front ends of the two barrels 11 and communicates with the flushing channels 111 of the two barrels 11. Liquid outlet check valves 3 that conduct in the liquid outlet direction are installed at the two positions in the inner cavity of the intermediate connection part 12 that communicate with the flushing channels 111. The liquid outlet check valve 3 can be an existing one-way valve flap valve (or other types of one-way valves, not limited here). It is in an automatically closed state when the water pressure is small, and the water flow can open the one-way valve flap valve when the water pressure reaches a certain level to form water flow conduction;

[0029] A needle tube docking part 13 and a flushing needle tube 4, the needle tube docking part 13 is fixedly connected and communicates with the intermediate connection part 12, and the flushing needle tube 4 is detachably inserted into the needle tube docking part 13 and communicates with the intermediate connection part 12.

[0030] Among them, Figure 2 As shown, the flusher also includes a fluid replenishment component for replenishing fluid to the two syringe bodies. The fluid replenishment component is located as a whole between the two barrels 11. The fluid replenishment component includes a three-way pipe 5. The three-way pipe 5 is formed by a main fluid replenishment pipe section 5a and two branch fluid replenishment pipe sections 5b connected in one piece. The main fluid replenishment pipe section 5a is used for liquid inlet, and the two branch fluid replenishment pipe sections 5b are fixedly connected to the two barrels 11 respectively; each barrel 11 has a side wall provided with a fluid replenishment through hole 112, and the fluid replenishment through hole 112 connects the branch fluid replenishment pipe section 5b and the flushing cavity 111.

[0031] A three-way stopcock 6 is installed at the confluence of the three-way pipes 5, and the three-way stopcock 6 is used to switch and conduct one of the branch infusion pipe sections 5b, so that the main infusion pipe section 5a can be connected to one of the branch infusion pipe sections 5b.

[0032] It also includes a connecting plate 14, which is fixedly connected to the rear ends of the two cylinders 11, and the rod-shaped portion of the piston rod 2 movably passes through the connecting plate 14; a liquid filling port 14a that can be opened and closed is provided on the connecting plate 14, and the liquid inlet end of the main liquid replenishing pipe section 5a of the three-way pipe 5 is fixedly connected to the connecting plate 14 and communicated with the liquid filling port 14a.

[0033] The liquid filling port 14a of the connecting plate 14 is detachably connected with a liquid filling cap 7. When no liquid is replenished, the liquid filling port 14a is covered with the liquid filling cap 7.

[0034] When replenishing the fluid, open the liquid filling cover 7, replenish the corresponding flushing fluid into the main liquid filling pipe section 5a of the three-way pipe 5 through the liquid filling port 14a, rotate the external handle of the three-way stopcock 6, and select the corresponding branch liquid filling pipe section 5b to connect to replenish the corresponding type of flushing fluid into the corresponding flushing cavity 111; the two flushing cavities 111 can be built with different types of flushing fluids.

[0035] During flushing, the corresponding flushing liquid is selected, and the piston rod 2 of the corresponding flushing channel 111 is selected to operate. When the piston rod 2 is pushed forward, the water pressure in the flushing channel 111 increases to flush open the liquid outlet one-way valve 3, so that the corresponding flushing liquid can be poured into the flushing needle tube 4 for output, thereby completing the root canal flushing operation.

[0036] In order to facilitate manufacturing, the barrel 11, the middle connecting portion 12, the needle tube docking portion 13 and the connecting plate 14 are integrally injection-molded to form a main body 1 that is convenient for hand-held operation.

[0037] As one of the process design solutions, the above-mentioned irrigation needle tube 4 is formed of a flexible material in one piece (full plastic), and can be pre-bent at different angles (can be bent arbitrarily). The inner diameter of the irrigation needle is 0.35mm, the outer diameter is 0.4-0.5mm, the end of the needle is closed, the outlet is on both sides, and the water output is large, which can prevent the irrigation liquid from exceeding the apical foramen and damaging the apical tissue due to excessive pressure. Through the above improvements, children's fear of dental treatment can also be reduced.

[0038] As one of the preferred connection methods, the needle tube docking part 13 is integrally configured as a circular sleeve structure, the inner hole of which is configured as a threaded hole, the connection end of the flushing needle tube 4 is integrally connected with a circular tubular threaded seat 41, the threaded seat 41 is connected to the flushing needle tube 4, and the outer wall of the threaded seat 41 is threadedly matched with the inner hole of the needle tube docking part 13. That is, the flushing needle tube 4 can be quickly installed by threaded connection, and the fixing scheme is reliable and easy to use.
