This invention provides a disposable, simple endotracheal intubation fixator for use in the field of endotracheal intubation. It includes a fixation tube with an adjusting sleeve and a threaded bolt connected to its inner wall. A knob drives the threaded bolt to press and adjust the adjusting sleeve, thereby fixing and locking the intubation tube to prevent slippage, displacement, and dislodgement. It employs a biomimetic integrated dental arch design, consisting of upper and lower occlusal plates and an elastic arc strip, preventing occlusal force from directly acting on the intubation tube and dispersing the biting force. Buffer pads are provided on the occlusal plates for cushioning and protection. Suction cups are added to the cheekbone area on both sides of the patient, connected to the fixation tube via an arc-shaped fixation frame. The bony support of the cheekbone reduces stress on facial soft tissues. Non-woven fabric patches are placed on the skin-contacting surfaces of the suction cups to keep the skin dry and clean. Elastic bands are incorporated into the arc-shaped fixation frame for double fixation, making it compatible with the needs of different patient groups and clinical scenarios.

The utility model relates to the technical field of veterinary instruments, disclose a kind of cattle oral cavity dilator, including occlusal plate, the bottom of occlusal plate is rotatably connected with two upper rotary rods, the other end of two upper rotary rods is rotatably connected with adjusting block, the bottom of two adjusting blocks is rotatably connected with lower rotary rod, the other end of two lower rotary rods is rotatably connected with another upper rotary rod, the inner wall of occlusal plate is slidably connected with two sliding rods, the bottom of two sliding rods is fixedly connected with fixed block, the outer wall of occlusal plate is equipped with the fixed component for dilator fixed on the head of cow, the fixed component includes adjusting band, the one end of adjusting band is fixedly connected with connecting band.The utility model makes the two occlusal plates of upper and lower open, so as to make occlusal plate open the mouth of cow, to realize the oral cavity of cow open, to realize the adjustment of the oral cavity of cow open.

This invention relates to an orthodontic appliance with an occlusal plate, comprising a fixed base, bracket wings, and an elastic element. The bracket wings are slidably positioned on the fixed base. The fixed base includes a base plate with an adhesive textured bottom surface and a wing seat located at one end of the base plate surface. The wing seat has a groove running along its central plane. The bracket wings include an occlusal plate, a sliding rod, and a groove for the archwire to pass through. The occlusal plate is located at the front end of the sliding rod, and the groove is located at the rear end of the sliding rod. The bracket wings are slidably positioned in the groove of the fixed base by means of the sliding rod and can move back and forth along the groove. The elastic element acts between the bracket wings and the wing seat, maintaining a stable position for both. The occlusal plate can be touched by the occluding teeth and generate orthodontic force. This orthodontic appliance design is uniquely conceived, structurally sound, and offers two usage methods, satisfying the needs of single-tooth and mandibular repositioning correction.

The application discloses an adjustable anesthetic cannula for an oral cavity cannula and relates to the technical field of anesthetic cannulas, which comprises a cannula body, one end of the cannula body is fixedly connected with an air bag a, the outer side of the cannula body is slidably connected with a bite plate, one end of the cannula body away from the air bag a is fixedly connected with a hard plastic tube, one end of the hard plastic tube is sleeved with a sleeve pipe, and one end of the sleeve pipe is fixedly connected with a hose. The adjustable anesthetic cannula for the oral cavity cannula is cooperated with the triple design of angle adjustment, double sealing and bite plate limiting, solves the pain points that the traditional cannula is easy to be inserted incorrectly due to the visual field shielding, the pipeline is bent due to the fixed interface angle, and the cannula is easy to be displaced, the movable bite plate guarantees the visual field of the cannula, the double-mode angle adjustment is adapted to the patient posture, the double sealing prevents drug overflow, the bite plate limiting fixes the cannula, the triple design takes into account the cannula accuracy, use adaptability and fixed stability, and improves the operation safety and patient comfort.

This invention discloses an intelligent denture modeling device based on oral scan data, relating to the field of dental prosthesis modeling. This device, by setting a light refraction acquisition component for emitting blue light at the end of the scanner and a bite plate on the mounting tube, allows the patient to bite down on the bite plate and exert force when collecting oral data. This puts the oral soft tissues in a stressed state, and the light refraction acquisition component at the front end, in conjunction with the scanner, captures the soft tissue displacement under the biting force, obtaining the patient's oral data under the stressed state. This helps medical personnel obtain functional pressure impressions and improves the accuracy of denture fabrication.
