Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an ultrasonic cleaning device for root canals. Background Technology

[0002] Pulp and periapical diseases are among the most common diseases in oral medicine, and root canal treatment is currently the accepted treatment method. The root canal treatment process typically includes three main steps: root canal shaping, root canal irrigation, and root canal filling. Root canal irrigation, also known as chemical preparation, is a crucial step in root canal treatment. Root canal irrigation uses a special fluid to remove infected material and debris from the root canal, creating conditions for subsequent disinfection and filling. Specifically, root canal irrigation uses chemical agents to disinfect the pulp chamber and root canals, and uses a sizing tip to flush out dentin debris from the pulp chamber and root canals, preventing root canal blockage. Irrigation solutions typically include sodium hypochlorite, chlorhexidine, EDTA, and physiological saline. After irrigation or during irrigation, especially when used in conjunction with a sizing tip, a negative pressure suction device is used to remove any remaining irrigation solution and dentin debris from the pulp chamber and root canals for subsequent root canal filling.

[0003] However, existing traditional root canal irrigation methods are ineffective at cleaning calcified root canals, C-shaped root canals, and root canals with open apical foramina. Furthermore, traditional irrigation methods require large amounts of irritating solution, which can cause chemical irritation and lead to postoperative periodontal pain. Additionally, airlocks can easily occur in the small apical regions within the root canal, resulting in insufficient irrigation and impacting subsequent treatment. Utility Model Content

[0004] To address the above technical problems, this utility model discloses an intracanal ultrasonic cleaning device that can perform both intracanal ultrasonic irrigation and intracanal rinsing. During the cleaning process, only the working tip needs to be replaced, without the need to switch to other equipment, making it convenient to operate and improving the cleaning efficiency of the intracanal wall.

Alternatively, the irrigation tube can be replaced with a root canal rinsing tip as needed for root canal rinsing. During the cleaning process, only the working tip needs to be changed; no other equipment needs to be switched, ensuring ease of operation for the physician and improving the efficiency of cleaning the root canal wall.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] This invention employs a structure combining an ultrasonic transducer and an irrigation module, enabling both intracanal ultrasonic vibration and intracanal irrigation. Under ultrasonic action, the fluid flowing out of the canal exhibits a cavitation effect, enhancing the cleaning effect on the root canal. Specifically, a lateral opening at the tip of the irrigation tube enables lateral positive pressure irrigation, preventing perforation of the apical orifice. Simultaneously, the ultrasonic transducer generates mechanical vibration at the tip of the irrigation tube, achieving a combined irrigation and ultrasonic vibration mode. The high-frequency mechanical vibration of the irrigation tube transfers energy to the irrigation fluid, powerfully flushing the root canal walls, isthmus, lateral branch canals, and biofilms and debris inaccessible to instruments, significantly improving root canal cleaning. This invention not only enables intracanal ultrasonic irrigation but also allows for root canal aeration by replacing the irrigation tube with a root canal aeration working tip.
