Temporomandibular joint dynamic nuclear magnetic resonance examination device

Abstract

The invention discloses a temporomandibular joint dynamic nuclear magnetic resonance examination device. The temporomandibular joint dynamic nuclear magnetic resonance examination device comprises an upper tooth socket and a lower tooth socket, a fixed shaft is fixedly connected with the outer side of the upper tooth socket, a rotating sleeve rotatably sleeves the outer side of the fixed shaft, a supporting rod is fixedly connected with the outer side of the rotating sleeve, a connecting shaft is fixedly connected with the bottom of the supporting rod, and a connecting plate rotatably sleeves the connecting shaft; and a sliding block is fixedly connected to the bottom of the connecting plate, a clamping strip is fixedly connected with the outer side of the sliding block, the part is used for dynamic magnetic resonance examination whether the positions of glenoid fossa, articular disc and condyle process are abnormal or not in the opening and closing process, in the process, a patient is helped to uniformly open and close the mouth, and good support is brought to clinical diagnosis.

Description

technical field [0001] The invention relates to the technical field of dental clinical auxiliary equipment, in particular to a dynamic nuclear magnetic resonance inspection device for temporomandibular joints. Background technique [0002] Modern people have a fast-paced life and high pressure. Some groups often experience temporomandibular joint pain. The typical symptom is that when talking or eating, they suddenly feel that the joints are stuck and cannot move. What’s more, the mouth cannot be opened. , or chewing pain, which can be relieved on its own when it is mild, and the pain will increase and the movement will be restricted when the symptoms are aggravated, seriously affecting daily life. It is called in medicine: temporomandibular joint dysfunction syndrome (TMJDS), which includes Temporomandibular joint snapping, pain, limited mouth opening, deviation, etc. This disease is more common in young adults, and the incidence rate is higher in women. It is the most comm...

[0002] Modern people have a fast-paced life and high pressure. Some groups often experience temporomandibular joint pain. The typical symptom is that when talking or eating, they suddenly feel that the joints are stuck and cannot move. What’s more, the mouth cannot be opened. , or chewing pain, which can be relieved on its own when it is mild, and the pain will increase and the movement will be restricted when the symptoms are aggravated, seriously affecting daily life. It is called in medicine: temporomandibular joint dysfunction syndrome (TMJDS), which includes Temporomandibular joint snapping, pain, limited mouth opening, deviation, etc. This disease is more common in young adults, and the incidence rate is higher in women. It is the most common disease in the oral and maxillofacial region. Magnetic resonance examination is used in modern clinical medicine. During this examination, the patient is required to evenly distribute the opening process into several steps, so that the regular mandibular joint changes can be displayed on the computer. However, the patient’s own facial muscles cannot complete the above actions, and equipment assistance is required.
