[0003] The cooling process of high-pressure
water cooling, combined with oral rinsing fluid and the large amount of
saliva secreted by the patient due to external stimuli during the treatment process, accumulated a large amount of
effusion in the oral cavity, which is extremely unfavorable to clinical operations. On the one hand, excessive oral effusion caused the patient’s subjective Discomfort, and it is easy to swallow and
choke by mistake. On the other hand, the oral effusion contains a large amount of
bacteria and dental debris, which pollutes the treatment wound and increases the chance of
postoperative infection. It is unclear and affects the precision of CAD /
CAM digital imaging. In order to remove the oral effusion generated in the patient's mouth, the doctor will stop the treatment intermittently, which prolongs the time of visiting the doctor and reduces the efficiency of diagnosis and treatment. The most commonly used method for effusion is 1. Negative pressure suction of saliva suction duct: this method requires the doctor to manually switch the operation action, the effusion is not completely removed, and the patient has a strong
foreign body sensation, which may easily lead to
nausea and coughing; 2. Rubber dam
Moisture isolation: This is currently the most
effective method, but the rubber dam
system has many components, including independent rubber dam cloth, rubber dam clips, facebows, punches, clamps and other tools, the operation is complicated, and the rubber dam clips are easy to collapse This further increases the risk of accidental
ingestion and aspiration of
foreign bodies in the oral cavity. Sometimes, due to insufficient tooth resistance, unexpected tooth fractures occur after clamping; and the rubber dam requires the cooperation of four-handed operation by oral professional nurses. Therefore, designing a device that can remove the oral effusion generated during the treatment process in a timely, efficient, convenient and safe manner and isolate the oral operating unit has a very positive role in stomatology.
[0004] In the limited space of the oral cavity, the doctor needs to hold a high-speed
mobile phone in one hand and a
mouth mirror in the other for coordinated protection during the
cutting process, which cannot take into account the isolation of the
buccal mucosa and tongue tissue at the same time, and accidentally injures the
buccal mucosa and tongue tissue. Even senior doctors with rich clinical experience can hardly avoid it. What's more frightening is that some children or adults with weak control are afraid of the harsh
noise produced by the high-speed rotation of the
turbine, or
muscle fatigue caused by long-term
mouth opening. The patient may not be able to control the behavior as agreed, and will suddenly shut up or dodge, accidentally damaging the surrounding
soft tissue, causing more serious medical disputes and medical accidents
[0005] It is also very important that the incidence of medical accidents caused by accidental removal of oral treatment instruments,
inhalation into the
respiratory tract or
ingestion into the
digestive tract by mistake is also very high, causing multiple mental and physical pains for patients, increasing
medical expenses and bringing harm to doctors. Psychological shadow, resulting in serious doctor-patient conflicts and disputes
[0006] In addition, during the diagnosis and treatment process, due to the long-term active
mouth opening and the fatigue of the occlusal muscles, it is easy to increase the discomfort of patients during diagnosis and treatment, and some patients will develop complications such as masseter
muscle spasm and
temporomandibular joint disorder syndrome.
[0007] Combining the above analysis, it can be seen that although auxiliary equipment such as mouth gags,
rubber dams, and saliva suction devices currently recommended in oral outpatient treatment can solve the above-mentioned problems in one aspect, they cannot fully meet the actual needs of
oral diagnosis and treatment, and these equipment Poor comfort during use, and even create psychological shadows in the minds of some children, leading to dental
phobias The installation and disassembly of the rubber dam is troublesome, and it needs to rely on the cooperation of professional dental nurses, which affects work efficiency and the effect of clinical promotion and use is not ideal
