Oral cavity supporting device

Abstract

The invention discloses an oral cavity supporting device comprising a fixed block. The fixed block is provided with a bearing, wherein the bearing is provided with a horizontally arranged screw. One end of the screw is provided with a turning handle. The screw is provided with a sliding nut. A first upper arm and a first lower arm are hinged to a bearing end of the screw. The first upper arm is hinged to an upper supporting block. The first lower arm is hinged to a lower supporting block. The other end of the upper supporting block is hinged to a second upper arm. The other end of the lower supporting block is hinged to a second lower arm. The second upper arm and the second lower arm are both hinged to the sliding nut. At original state, the oral cavity supporting device is linearly arranged. Then the oral cavity supporting device is put inside an oral cavity of a patient. The upper supporting block and the lower support block are relatively fixed by occlusal force. With the movement of the sliding nut along the screw, a supporting structure is formed and a patient's oral cavity is pushed open. The oral cavity supporting device is easy in operation and labor-saving. The range of the supporting structure can be precisely adjusted by the screw so that a patient feels comfortable.

Description

technical field [0001] The invention relates to medical equipment, in particular to an oral cavity support device. Background technique [0002] At present, in oral and dental treatment methods, including filling, pulp opening, pulp cutting, dry pulp, root canal treatment, plasticizing treatment, scaling and so on. Regardless of the treatment method, the patient needs to open his or her own mouth. After a long treatment time, the patient will feel very uncomfortable and tired, which will affect the treatment effect and delay the treatment time. In some cases, occlusal joint disease will occur. Especially in patients with severe facial burns, it is necessary to prevent facial contractures and mouth corner deformities caused by contractures. However, there is no corresponding supporting device in the prior art, or the structure is simple and the operation is inconvenient, which is likely to cause secondary injuries to patients or permanent irreparable damage.

Regardless of the treatment method, the patient needs to open his or her own mouth. After a long treatment time, the patient will feel very uncomfortable and tired, which will affect the treatment effect and delay the treatment time. In some cases, occlusal joint disease will occur.

Especially in patients with severe facial burns, it is necessary to prevent facial contractures and mouth corner deformities caused by contractures. However, there is no corresponding supporting device in the prior art, or the structure is simple and the operation is inconvenient, which is likely to cause secondary injuries to patients or permanent irreparable damage
