[0001] The invention belongs to the technical field of mandibular osteomyelitis surgery equipment, and relates to a head-mounted surgical auxiliary positioning lighting device, in particular to a head-mounted mandibular osteomyelitis surgery auxiliary positioning lighting device. Background Art
[0002] Mandibular osteomyelitis is caused by pathogen infection, ionizing radiation or chemical factors, which cause inflammatory lesions in the entire bone tissue components such as the mandibular periosteum, bone density, bone marrow, and blood vessels and nerves in the bone marrow cavity. During mandibular osteomyelitis surgery, because the lesion is located on the jaw, when the operation is performed through the mouth, the location and boundaries of the lesion can be located, allowing the doctor to more accurately remove the diseased tissue. During the operation, the patient is required to keep his mouth open, but because the oral cavity is small and deep, the vision is poor, and lighting equipment is required.
[0003] Existing oral lighting lamps for dental surgery are installed by slidingly connecting a connecting rod. The connecting rod is long, and it is not convenient to rotate to adjust the irradiation angle of the oral lighting lamp. It cannot be accurately aimed at the surgical site, and subtle lesions are often not visible. The burden on the surgeon's eyes is greatly increased. At the same time, the oral lighting lamp directly irradiates the patient, which can easily cause eye discomfort to the patient, making the patient feel glare and other discomfort.
[0004] After searching, for example, a Chinese patent document discloses a surgical auxiliary positioning lighting device for mandibular osteomyelitis, with the announcement number: CN222130301U. This surgical auxiliary positioning lighting device includes a positioning guide plate, which includes a tooth brace and a wound cover plate, a connecting plate is integrally formed between the tooth brace and the wound cover plate, a sliding groove is provided at the rear end of the connecting plate, a slider is slidably connected in the sliding groove, a bolt is fixed at the upper position of the rear end of the slider, a long groove for the bolt to slide is provided on the connecting plate, a connecting mechanism is provided at the lower position of the rear end of the slider, and a supporting mechanism is provided on the connecting mechanism.
[0005] Although the surgical auxiliary positioning lighting device disclosed in this patent uses a positioning guide to locate the mandibular osteomyelitis lesion in real time and maintain the illumination of the surgical field, the patient is installed and supported by a resistance plate, and the fixing effect is limited. It is unable to effectively ensure the authenticity and firmness of the device and the patient when wearing it. In addition, it is inconvenient to adjust the lamp beads inside the patient's mouth through the gooseneck tube. At the same time, the wound plate easily covers and blocks the lesion inside the patient's mouth, making it inconvenient for doctors to perform precise mandibular osteomyelitis surgery.
