[0012] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. The embodiments in the basic utility model and all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0013] like Figure 1 , 2 The needle seat 4 includes a needle seat 4, the upper end of which is connected to the nickel-titanium needle tube 1 and the stainless steel outer sleeve 2, the stainless steel outer sleeve 2 is sleeved on the nickel-titanium needle tube 1, the front end of the nickel-titanium needle tube 1 is provided with a working part 5 exposed outside the stainless steel outer sleeve 2, and the rear end of the nickel-titanium needle tube 1 is located in the inner cavity of the needle seat 4. The nickel-titanium needle tube 1 is made of nickel-titanium material, which has excellent flexibility and fatigue resistance, can adaptively displace in a narrow and curved root canal and ensure that the needle tube does not break in the root canal. The stainless steel outer sleeve 2 is sleeved on the outside of the nickel-titanium needle tube 1, and its main purpose is to protect and support the non-working part of the nickel-titanium needle tube from damage and bending during root canal flushing, prevent the water outlet channel from being blocked, and ensure the root canal flushing effect.

[0014] In order to facilitate the connection of the needle seat 4 with the syringe, a thread connected to the syringe is provided on the needle seat 4.

[0015] The upper end of the needle seat 4 is provided with a connecting section for fixing the nickel-titanium needle tube 1 and the stainless steel outer sleeve 2, and the upper end of the connecting section is provided with an inner groove, and the inner groove is provided with an AB glue layer 3 for fixing the nickel-titanium needle tube 1 and the stainless steel outer sleeve 2. The AB glue layer 3 glues the needle seat 4, the nickel-titanium needle tube 1, and the stainless steel outer sleeve 2 together.

[0016] Working principle: This nickel-titanium dental irrigation needle with an outer sleeve is used to remove debris or debris in the oral cavity. When the irrigation needle is working, it needs to be used in conjunction with a syringe. First, the needle seat 4 is connected to the syringe through a thread. Before root canal irrigation, the operator can pre-bend the working part 5 of the nickel-titanium needle tube 1 according to the size and shape of the root canal to be rinsed. After pre-bending, the working part 5 of the nickel-titanium needle tube 1 is slowly extended into the root canal until it is 0.5mm away from the bottom of the root canal, and the syringe handle is slowly and evenly pushed to inject the irrigation liquid into the root canal.

[0017] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
