Description

Technical Field

[0001] This invention relates to the field of root canal cleaning, and more particularly to a pen-style apical negative pressure suction root canal irrigation device. Background Technology

[0002] Due to the "vapor lock effect" in the apical region of the root canal, current irrigation techniques struggle to reach this area, leading to debris accumulation and residual infection, thus reducing the success rate of root canal treatment. Current root canal irrigation techniques often use disposable irrigators similar to syringe needles. These are difficult to reach the apical region and require assistants to suction out excess sodium hypochlorite to prevent leakage into the oral cavity and potential mucosal burns (even with a rubber dam, this risk remains). This is labor-intensive and reduces treatment efficiency. In contrast, pen-style handles, similar to those used in root canal preparation, are more familiar to clinicians, easier to operate, and save clinical time. Summary of the Invention

The rotatable flushing housing, combined with a multi-speed flushing nozzle, allows for flexible adjustment of the flushing angle, ensuring the flushing solution precisely reaches the apical region. The synchronized negative pressure suction structure integrates flushing and suction, preventing secondary accumulation of debris and flushing solution, and thoroughly resolving the problem of incomplete apical flushing.

[0020] 2. The suction speed can be precisely controlled to meet diverse clinical needs. By adjusting the position of the locking ball through the drive component, the diameter of the suction tube can be flexibly changed to adjust the suction speed.

[0022] 4. An additional irrigation fluid heating function has been added to balance treatment effectiveness and patient comfort. The irrigation shell is equipped with a detachable heating sleeve, which can adjust the irrigation fluid to a suitable temperature for the human body, avoiding low-temperature stimulation to patients and enhancing the chemical activity of the irrigation fluid to improve cleaning effect.

[0023] 5. The pen-style design aligns with clinical operating habits, enabling efficient single-person operation. The device uses a pen-style handle familiar to doctors, allowing for single-handed operation of functions such as irrigation and aspiration, lighting, and speed adjustment, saving clinical time. The integrated irrigation and aspiration design eliminates the need for an assistant to suction saliva, reducing manpower consumption and enabling timely removal of high-concentration irrigation solutions, avoiding oral mucosal burns and improving treatment safety.

[0024] 6. Multifunctional integrated base, solving the problem of traditional bases having only one function. The base integrates functions such as device placement, irrigation fluid storage and recycling, and equipment charging. It achieves automatic control of irrigation fluid through the pump and valves, can stably place the device, and optimize the cleanliness of the treatment environment.

[0025] 7. Modular and detachable design, meeting clinical hygiene standards and reducing maintenance costs. The device features multiple detachable sections, facilitating disinfection, cleaning, and parts replacement, thus meeting clinical hygiene requirements. It also makes troubleshooting easier, effectively extending the device's lifespan and reducing maintenance costs. Attached Figure Description

[0048] The specific implementation method is as follows: After detachably connecting the first tube flushing housing 6 and the second tube flushing housing 7, press the lighting and ball control switch 112 to start the lighting power supply 1202 through electrical connection, output power to the lighting lamp 1201, turn on the lighting lamp 1201 for illumination, and at the same time, transmit the start command to the drive motor 110 through the control shaft 111 to drive the third drive shaft 109 to rotate, transmit rotational power to drive the first drive shaft 106, the linkage shaft 107 and the second drive shaft 108 to rotate, so that the two control plates 105 meshing below the first drive shaft 106 and the second drive shaft 108 slowly move towards the center of the water suction needle body 102. The two control plates 105 on both sides squeeze the locking ball 104 located inside the water suction needle body 102 upward, so that the top of the water suction internal pipe 103 is unobstructed; press the heat preservation. Heating switch 204 activates the heat insulation heating jacket 203 to heat the rinsing liquid inside the flushing housing 202; the suction needle 101 and the flushing nozzle 201 are aligned with the apical region of the patient's root canal, and the flushing control switch 5 is activated to flush and clean the apical region of the patient's root canal and draw up the rinsing liquid; after flushing, all switches are turned off, and one end of the detachable press-type valve of the second root canal flushing housing 7 is placed on the suction receiving tube sleeve 1105 and the flushing receiving tube sleeve 1106 on the flushing device placement slot 1108. The valve controls the switch 1107 to transport the rinsing liquid inside the first suction tube 3 and the first flushing tube 4 in the second root canal flushing housing 7 to the rinsing liquid storage tank structure 9 and the rinsing liquid recovery tank structure 8 through the second suction tube 1101 and the second flushing tube 1102, thus completing the entire root canal flushing process.

[0049] The beneficial effects of this invention are reflected in:

[0050] 1. Effectively overcomes the "steam lock effect" in the apical region, improving the success rate of root canal treatment. The rotatable flushing housing, combined with a multi-speed flushing nozzle, allows for flexible adjustment of the flushing angle, ensuring the flushing solution precisely reaches the apical region. The synchronized negative pressure suction structure integrates flushing and suction, preventing secondary accumulation of debris and flushing solution, and thoroughly resolving the problem of incomplete apical flushing.

[0051] 2. The suction speed can be precisely controlled to meet diverse clinical needs. By adjusting the position of the locking ball through the drive component, the diameter of the suction tube can be flexibly changed to adjust the suction speed. The suction needle is detachable, taking into account both the flexibility of use and clinical hygiene requirements.

[0052] 3. Integrated lighting device reduces the difficulty of clinical operation. A linked lighting device is installed between the suction and flushing structures to provide a clear view of the inside of the root canal, eliminating the need for additional lighting equipment, improving the accuracy of the flushing operation, and simplifying the clinical process.

[0053] 4. An additional irrigation fluid heating function has been added to balance treatment effectiveness and patient comfort. The irrigation shell is equipped with a detachable heating sleeve, which can adjust the irrigation fluid to a suitable temperature for the human body, avoiding low-temperature stimulation to patients and enhancing the chemical activity of the irrigation fluid to improve cleaning effect.

[0054] 5. The pen-style design aligns with clinical operating habits, enabling efficient single-person operation. The device uses a pen-style handle familiar to doctors, allowing for single-handed operation of functions such as irrigation and aspiration, lighting, and speed adjustment, saving clinical time. The integrated irrigation and aspiration design eliminates the need for an assistant to suction saliva, reducing manpower consumption and enabling timely removal of high-concentration irrigation solutions, avoiding oral mucosal burns and improving treatment safety.

[0055] 6. Multifunctional integrated base, solving the problem of traditional bases having only one function. The base integrates functions such as device placement, irrigation fluid storage and recycling, and equipment charging. It achieves automatic control of irrigation fluid through the pump and valves, can stably place the device, and optimize the cleanliness of the treatment environment.

[0056] 7. Modular and detachable design, meeting clinical hygiene standards and reducing maintenance costs. The device features multiple detachable sections, facilitating disinfection, cleaning, and parts replacement, thus meeting clinical hygiene requirements. It also makes troubleshooting easier, effectively extending the device's lifespan and reducing maintenance costs.
