Description

Technical Field

[0001] The invention relates to the technical field of oral treatment, and in particular to a fixed saliva suction tube device with adjustable opening degree. Background Art

[0002] The saliva suction tube is an important instrument used in almost all operations in the dental department. There are two types of saliva suction tubes: disposable and reusable. Disposable saliva suction tubes are discarded after use to avoid cross infection and facilitate disposal, while reusable saliva suction tubes need to undergo a strict disinfection procedure to ensure their sterility.

[0003] The existing weak suction saliva tube is the most common type of saliva tube in oral clinics, usually composed of a suction head, a drainage tube and a copper wire; the suction head is used to filter large pieces of debris such as dental calculus to prevent machine clogging; the drainage tube is responsible for discharging the sucked liquid; the copper wire is used to adjust the angle of the saliva tube to better adapt to the patient's oral structure. When the patient's mouth is constantly secreting saliva, the saliva tube can absorb the exudate and secretion in the mouth to prevent the patient from sitting up and vomiting frequently. However, during the treatment process, for different patients, due to the limitations of the patient's age or oral size, the angle of opening between the upper and lower teeth of different patients is different. Although the jaw pad on the traditional saliva tube with a jaw pad can separate the patient's upper and lower teeth, due to the fixed size of the existing jaw pad, the opening degree between the upper and lower teeth cannot be adjusted according to the doctor's operation. The patient needs to open his mouth to adjust the size of the mouth by himself, which is easy to cause the jaw pad to detach from the mouth, and the patient's mouth opening for a long time is easy to cause soreness and weakness of the upper and lower jaws, resulting in the closure of the upper and lower jaws. It is inconvenient for the doctor to manually adjust the opening degree of the patient's mouth, which affects the doctor's operation and treatment efficiency of the oral cavity.

[0053] (1) The present invention facilitates the rotation of the auxiliary mechanism by the doctor through the coordinated arrangement of the jaw pad mechanism, the adjustment mechanism and the auxiliary mechanism, so that the doctor can push the adjustment mechanism. The jaw pad mechanism includes an upper jaw pad, a lower jaw pad, a convex strip, a limit assembly and a connector. Through the push of the adjustment mechanism, the height between the upper jaw pad and the lower jaw pad can be adjusted, so that the mouth opening degree of the patient biting the jaw pad mechanism can be adjusted. The doctor can adjust the size of the patient's mouth opening appropriately by operating the auxiliary mechanism outside the patient's mouth. The doctor does not need to put his hand into the patient's mouth, so that the doctor can conveniently adjust the mouth opening degree during the oral operation, thereby improving the doctor's oral operation efficiency;

[0054] (2) The present invention uses the configuration mode of cooperating the jaw pad mechanism and the saliva suction mechanism, and utilizes the structural characteristics of the maxillary pad and the mandibular pad to facilitate the patient's bite of the jaw pad mechanism, and increases the friction between the mandibular pad and the posterior molars by the convex strips, so that the position of the mandibular pad in the posterior molar area is more stable. When the doctor adjusts the patient's oral cavity, he clamps the support plate on the auxiliary mechanism and rotates the rotating column. Under the position limitation of the limit assembly, the pushing of the adjustment mechanism between the maxillary pad and the mandibular pad will not cause the maxillary pad and the mandibular pad to move in the front-back direction, so that the distance adjustment between the maxillary pad and the mandibular pad is more stable;

[0055] (3) The present invention adopts the setting mode of the adjustment mechanism, wherein the adjustment mechanism includes a groove body, a pushing component, a positioning block and a pushing component. Through the setting of the groove body, when the pushing component pushes the pushing component, the height between the upper jaw pad and the lower jaw pad can be slowly adjusted, so that the patient is always in a occlusal state, and the patient does not need to control the size of the mouth opening. In addition, one side of the jaw pad mechanism fits tightly with the oral cavity, which can block the tongue and prevent the patient from biting the soft tissue of the oral cavity due to the movement of the upper and lower jaws, thereby improving the protection performance of the soft tissue in the oral cavity.

The doctor uses clamps to adjust the liquid inlet direction of the two cavities at one end of the tube body 31. When it is necessary to adjust the patient's oral opening, the doctor holds the support plate 52 with one hand to prevent the mandibular pad 22 from moving, and uses the other hand to rotate By moving the rotating block 6 and rotating the rotating column 53, the screw 441 can be rotated. Through the threaded connection between the screw 441 and the positioning block 43, the rotating head 442 pushes the moving block 423, so that the push block 421 moves between the maxillary pad 21 and the mandibular pad 22. Through the position limitation of the clamping column 422 and the special-shaped groove 413, the clamping column 422 can push the upper bite block 211, so that the maxillary pad 21 and the mandibular pad 22 can be adjusted in height, so that the patient's mouth can be opened to different degrees, which is suitable for doctors' oral treatment operations and improves the convenience of operation.
