Technical Field
The invention relates to the technical field of surgical instruments, in particular to a spreader for an alveolar bone and jawbone fine adjustment operation and a manufacturing method thereof.
Background
The shape of a face is mainly affected by the present condition of facial bones and the shape of oral bones, and in a medical shaping process, fine adjustment (displacement, cutting, etc.) of alveolar bones and jawbones is generally required for adjusting the shape of the face. In order to avoid leaving wounds on the face, current alveolar bone and jaw fine adjustment procedures employ incisions from the inside of the mouth to perform the procedure. Therefore, during the operation, the patient is required to open the oral cavity completely, so that the doctor can perform the operation.
Because it is difficult for the patient to open the mouth for a long time by himself, an distractor is required to distract the patient's mouth. At present, however, the existing distractors used in the alveolar bone and jawbone fine adjustment operation are all general distractors used in oral treatment, and the distractors are used for the alveolar bone and jawbone fine adjustment operation and have the following problems: 1. in addition to the operation of the alveolar bone and jaw fine adjustment, the cheek of the patient needs to be supported from the inside of the oral cavity, but the oral cavity spreader only spreads the oral cavity, so that the doctor needs to use an additional tool to prop up the cheek of the patient during the operation, which makes the operation of the doctor difficult. 2. The existing oral cavity distractor is universal, but the mouth shapes and bone structures of different patients are different, so that the distractor can bring serious discomfort to some patients.

Fig. 2 is a schematic view showing the state of use of the distractor for alveolar bone and jaw fine adjustment according to the present invention (cheek is not shown in order to show the distractor arm in the oral cavity).
Fig. 3 is a schematic view showing the structure of a maxillary abutment of the distractor for an alveolar bone and jaw fine adjustment operation according to the present invention.
Detailed Description
The invention will be further described with reference to the following examples.
The specific embodiment of the distractor for the alveolar bone and jaw fine adjustment according to the present invention, as shown in fig. 1 and 2, includes: the lower jaw clamping seat 1, the upper jaw supporting seat 2 and the connecting bridge 3, the connecting bridge 3 is connected between the lower jaw clamping seat 1 and the upper jaw supporting seat 2, the upper jaw supporting seat 2 comprises a main rod frame 21, two ends of the main rod frame 21 respectively extend to form a bending arch-shaped supporting and expanding arm 22, and a connecting part of the main rod frame 21 and the supporting and expanding arm 22 is provided with an upper jaw clamping protrusion 23 for clamping upper jaws. When in use, the lower jaw clamping seat 1 clamps the lower jaw of a patient, and the upper jaw clamping bulge 23 of the upper jaw supporting seat 2 clamps the upper jaw of the patient, so that the supporting device can be effectively fixed in the oral cavity, and the connecting bridge 3 connected between the lower jaw clamping seat 1 and the upper jaw supporting seat 2 can fully open the oral cavity of the patient, in addition, as the two ends of the main rod frame 21 respectively extend to form the bending-shaped supporting arms 22, when the supporting device is placed in the oral cavity, the supporting arms 22 can support the cheek of the patient from the inside of the oral cavity, thereby facilitating the operation of a doctor.
