Description

Technical Field

[0001] This utility model belongs to the field of medical devices, specifically a root canal cleaning auxiliary device. Background Technology

[0002] In dental root canal treatment, root canal cleaning is a crucial step that directly affects the success or failure of the treatment. Currently, commonly used root canal irrigation needles are typically designed with flat or blunt tips, with single or multiple holes on the side, and are connected to an irrigation solution supply device via a quick connector to deliver irrigation solution for cleaning the root canal.

[0003] However, during irrigation, the irrigating solution is prone to overflowing from the root canal orifice, which not only contaminates the patient's oral environment but also increases the potential risk of the patient swallowing the irrigating material, posing a threat to their health. Furthermore, due to the limited spray pattern and position of the side openings, the flow trajectory of the irrigating solution after exiting the side openings is relatively uniform, limiting the irrigation range. Especially when facing the curved sections of the root canal wall, conventional irrigation methods are insufficient to effectively flush out bacteria, debris, and residual pulp tissue within the root canal. These problems not only reduce the efficiency of root canal treatment but may also lead to postoperative complications such as infection, affecting the treatment outcome and the patient's oral health recovery. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a root canal cleaning auxiliary device to solve the problem in the prior art where root canal irrigation fluid easily overflows and contaminates the oral cavity, posing a high risk of accidental swallowing.

[0005] A root canal cleaning aid includes a quick connector connected to an irrigation fluid supply device. The quick connector has a needle tube at one end, and the distal end of the needle tube has several sets of side holes. An adsorption assembly is fitted onto the needle tube, and the adsorption assembly includes an adsorption cotton strip mounted on the needle tube for adsorbing root canal irrigation fluid.

[0006] Preferably, the syringe includes a proximal rigid section communicating with a quick connector, an arc-shaped section at the end of the proximal rigid section, a distal flushing section at the end of the arc-shaped section, a tip at the end of the distal flushing section, and a plurality of side holes disposed on the distal flushing section near the tip.

[0007] Preferably, the two sets of side holes are designed with an oblique liquid outlet.

[0008] One set of the side holes discharges liquid at an angle to the front, and the other set of the side holes discharges liquid at an angle to the rear.

[0009] Preferably, the liquid discharge trajectory of the side hole is tangent to the inner tangent of the distal flushing section.

[0010] Preferably, the distal rinsing section is provided with anti-slip ridges, and an elastic ring is provided on the outer side of the anti-slip ridges, with the absorbent cotton strip disposed on the elastic ring.

[0011] Preferably, the quick connector is a Luer connector.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model uses an elastic ring to attach the absorbent cotton strip to the syringe, and the elastic ring is firmly fixed by anti-slip ridges. During the rinsing process, it can automatically fit the root canal entrance and absorb the overflowing rinsing fluid in time, avoiding the risk of rinsing fluid contaminating the oral environment and patients swallowing the rinsing material.

[0014] 2. This utility model uses two sets of side holes with oblique liquid outlets and the liquid outlet trajectory is tangent to the inner tangent of the distal rinsing section. This allows the rinsing liquid to form a spiral rinsing flow in the root canal, which can more comprehensively and deeply rinse the inner wall of the root canal, effectively remove bacteria, debris and residual pulp tissue in the root canal, and improve the success rate of root canal treatment.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] As attached Figure 1 To be continued Figure 3 As shown:

[0022] This utility model provides a root canal cleaning auxiliary device, which consists of a quick connector 2, a needle tube 1 and an adsorption component 3, wherein the quick connector 2 is connected to the irrigation fluid supply device 5 to provide a channel for the delivery of irrigation fluid.

[0023] As attached Figure 1 To be continued Figure 3 As shown: Quick connector 2 is a Luer connector, which features tight connection, convenient operation and strong compatibility. It can be stably connected with common flushing fluid supply devices 5 (such as syringes and infusion pumps) to prevent flushing fluid leakage.

[0024] As attached Figure 1 To be continued Figure 3 As shown: The needle tube 1 includes a proximal rigid section 101 that communicates with the quick connector 2. The end of the proximal rigid section 101 is provided with an arc-shaped section 102. The end of the arc-shaped section 102 is connected to the distal irrigation section 103. The end of the distal irrigation section 103 is provided with a tip 104. This three-section structure design facilitates the needle tube 1 to penetrate deep into the root canal for operation.

[0025] As attached Figure 3 As shown: The distal rinsing section 103 is provided with anti-slip ridges 105 to increase the friction between it and the adsorption component 3.

[0026] As attached Figure 3 As shown: Several sets of side holes 4 are provided on the distal irrigation section 103 near the end 104. Two sets of side holes 4 adopt an oblique liquid discharge design, one set discharges liquid obliquely forward and the other set discharges liquid obliquely backward. The discharge trajectory of the side holes 4 is tangent to the inner tangent surface of the distal irrigation section 103. This design allows the irrigation fluid to form a spiral irrigation flow along the root canal wall after being sprayed from the side holes 4, increasing the coverage area of ​​the irrigation fluid and effectively improving the root canal cleaning effect.

[0027] As attached Figure 3 As shown: The adsorption component 3 includes an adsorption cotton strip 301 disposed on the needle tube 1. The adsorption cotton strip 301 is sleeved on the outside of the anti-slip ridge 105 by an elastic ring 302. The anti-slip ridge 105 increases the friction between the elastic ring 302 and the needle tube 1, so that the elastic ring 302 can be securely sleeved on the needle tube 1, ensuring the stable position of the adsorption cotton strip 301 and continuously and effectively adsorbing the rinsing fluid overflowing from the root canal orifice during the rinsing process.

[0028] Working principle: During root canal cleaning in dental root canal treatment, the dentist first connects the quick connector 2 tightly to the irrigating solution supply device 5 to ensure smooth delivery of the irrigating solution. Then, depending on the specific condition of the patient's root canal, the needle 1 is slowly inserted into the root canal through the quick connector 2. Because the needle 1 has a proximal rigid section 101, an arc-shaped section 102, and a distal irrigating section 103, it facilitates the needle reaching the appropriate position inside the root canal.

[0029] During insertion, the absorbent cotton strip 301, which is fitted onto the outside of the needle tube 1 by the elastic ring 302, will naturally adhere to the root canal entrance. When the irrigating solution supply device 5 starts to deliver irrigating solution, the irrigating solution enters the needle tube 1 through the quick connector 2 and is ejected from the side holes 4 on the distal irrigating section 103. Because the side holes 4 adopt an oblique dispensing design, one set of dispensing solution is obliquely forward and the other set is obliquely backward, and the dispensing trajectory is tangential to the inner tangent surface of the distal irrigating section 103, the irrigating solution will form a spiral irrigating flow in the root canal, thoroughly irrigating the inner wall of the root canal.

[0030] During the rinsing process, any rinsing fluid overflowing from the root canal orifice will be promptly absorbed by absorbent cotton swab 301, maintaining a clean oral environment. After rinsing, remove syringe 1 from the root canal, unscrew quick connector 2, and discard the root canal cleaning needle into the medical waste collection bin.

Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
