Description

Oral cavity occlusion fixing device for protecting stable palate bone in cleft palate patient operation

Technical Field

The utility model belongs to the field of medical equipment, and particularly relates to a meshing fixing device.

Background

The secondary jawbone deformity of patients with cleft lip and palate is one of the clinically common jawbone development deformity types. Serious cleft lip and palate infants have skeletal development deformity of the maxillofacial region, and the patients with cleft lip and palate usually have jaw deformity with different degrees due to the need of orthognathic surgery, and the surgical methods comprise conventional orthognathic surgery and maxillary traction osteogenesis. The most common of conventional orthognathic surgery is the Lefort type I osteotomy, which is suitable for light to moderate posterior maxillary deformities, and sometimes requires the cooperation of a bilateral mandibular ascending sagittal split osteotomy (BSSRO) and a chin shaping surgery to further improve facial and bite relationships. The maxillary traction osteogenesis can be performed by using an external or internal traction device, and the osteotomy can be a LeFort I-type osteotomy or a maxillary anterior osteotomy according to treatment requirements. Orthognathic surgery and traction osteogenesis have advantages and limitations, and how to select a proper treatment scheme should comprehensively analyze the illness state of a patient and the clinical experience of a doctor, and fully communicate with the patient to obtain a good correction effect; however, the cleft lip patient has incomplete development of the cleft lip bone and a certain range of the cleft lip bone is lacking, so that when the bone cutting of the maxilla is performed, the cleft lip bone of the maxilla is connected too little or not, and the fracture of the maxilla can occur in the operation, thereby affecting the integrity and stability of the whole maxilla.

Disclosure of Invention

In order to solve the problems, the utility model aims to provide an oral occlusion fixing device for protecting the stability of a jawbone in a cleft palate patient operation, which can effectively avoid the fracture of the upper jaw in operation by using the device when the jawbone is cut, thereby ensuring the integrity and the stability of the jawbone.

In order to achieve the above object, the present utility model has the following technical scheme.

An oral occlusion fixing device for protecting the stability of a jawbone in a cleft palate patient operation is characterized by comprising a tooth socket part corresponding to teeth and a supporting part corresponding to the soft tissue outline of a hard palate; the upper side of the supporting part is a supporting surface matched with the outline of hard palate soft tissue, two ends of the supporting part are fixed with two ends of the tooth socket part, and an upper tooth socket corresponding to the upper teeth is arranged on the upper side of the tooth socket part.

In the device, the supporting part is arranged to carry out fitting support on hard palate soft tissues, so that a patient can more easily keep the fixation of palate bones; the arrangement of the upper tooth socket corresponds to the tooth shape on the oral cavity, so that the device is more convenient to align when in use, the requirement of positioning precision is met, and the device is fixed in position through tooth occlusion after aligning, so that the device has the effect of repeatable use. Namely, the device can effectively avoid the fracture of the upper jaw in the operation, so as to ensure the integrity and stability of the upper jaw; and is more convenient in use.

Further, a lower socket corresponding to the lower tooth is provided on the upper side of the socket part. The arrangement of the lower tooth socket can enable the device to be aligned with the position more accurately when in use, and the positioning precision is further improved. And in use, the device is more stably fixed by occlusion of the upper and lower teeth.

Further, the whole tooth socket part and the supporting part are of arc-shaped structures.

Further, the left and right ends of the tooth socket part and the left and right ends of the supporting part are fixed, and a weight-reducing notch is formed between the front side of the supporting part and the rear side of the tooth socket part. The weight of the device can be effectively reduced and the cost can be reduced while the use effect of the device is ensured by the arrangement of the weight-reducing notch.

Further, the device is formed integrally for 3D printing. The integrated into one piece's setting for its overall structure intensity is higher, can support better.

Further, the device is composed of a resin material. The resin material is medical grade resin material.

The device has the beneficial effects that the supporting part is arranged to carry out attaching support on hard palate soft tissues, so that a patient can more easily keep the fixation of palate bones; the arrangement of the upper tooth socket corresponds to the tooth shape on the oral cavity, so that the device is more convenient to align when in use, the requirement of positioning precision is met, and the device is fixed in position through tooth occlusion after aligning, so that the device has the effect of repeatable use. Namely, the device can effectively avoid the fracture of the upper jaw in the operation, so as to ensure the integrity and stability of the upper jaw; and is more convenient in use.
