Ultrasonic flushing instrument

Abstract

The invention provides an ultrasonic flushing instrument and relates to the field of oral medical instruments. The ultrasonic flushing instrument comprises a liquid storage tank, an ultrasonic generator, a first water pump, a second water pump, a recovery tank, a handle, a back suction cavity, a flushing syringe needle, a connecting pipe, a flushing head, a first supporting rod, a second supporting rod, a first switch, a second switch, a third switch and multiple infusion tubes. In the using process, the first switch is turned on, disinfectant liquid can be sprayed to root canals of the teeth of a patient, the third switch is turned on at the same time, sound waves generated by the ultrasonic generator can be used for loosening scraps and a smear layer on the root canal wall of the teeth during root canal preparation to facilitate flushing and cleaning through the disinfectant liquid, and the second switch can be turned on at the same time to suck back the disinfectant liquid in a tooth marrow cavity into the recovery tank in time. The ultrasonic flushing instrument is convenient to operate, saves time and labor, makes the time of a doctor beside a chair shorter, improves treatment quality by the doctor and economical efficiency, and relieves the pain of the patient.

Description

technical field [0001] The invention relates to the field of oral medical instruments, in particular to an ultrasonic rinser. Background technique [0002] At present, most domestic root canal treatments use syringes to extract disinfectant to clean the root canals, which has low benefits and poor flushing quality. Moreover, most of the domestic dental medical institutions do not use rubber dams, and the disinfectant will directly flow into the mouth during flushing. Disinfectants with high concentrations are highly irritating and can easily cause chemical burns to the oral mucosa, with unpleasant smell and bad taste, which will make patients feel uncomfortable. Therefore, only low-concentration disinfectant can be used to disinfect the oral cavity, but the effect of this kind of disinfection is not good, the taste is not good, and it is time-consuming and laborious.

Problems solved by technology

[0002] At present, most domestic root canal treatments use syringes to extract disinfectant to clean the root canals, which has low benefits and poor flushing quality. Moreover, most of the domestic dental medical institutions do not use rubber dams, and the disinfectant will directly flow into the mouth during flushing. Disinfectants with high concentrations are highly irritating and can easily cause chemical burns to the oral mucosa, with unpleasant smell and bad taste, which will make patients feel uncomfortable

Therefore, only low-concentration disinfectant can be used to disinfect the oral cavity, but the effect of this kind of disinfection is not good, the taste is not good, and it is time-consuming and laborious. Another way is to use an ultrasonic scaler with an ultrasonic file, because the disinfectant will Corrosion of the scaler handle and pipeline, so this method can only be rinsed with distilled water, and the liquid flows from the root canal of the tooth into the root canal during cleaning, which is not effective for root canal cleaning

Because the ultrasonic root canal file is a kind of miniature file, it will cause steps to the root canal wall of the tooth, thus making it difficult to prepare and fill the root canal. Such an operation process not only causes inconvenience to the doctor, but also increases the chair time increased patient suffering
