Problems solved by technology

[0003] At present, most of the existing distraction osteogenizers at home and abroad for reconstructing the front defect of the maxilla are suitable for straight bone distraction, and there are basically no distractors suitable for the arcuate defect of the front of the mandible. Osteogenesis still has a series of problems such as relatively narrow scope of application, inability to fully embed the device in the oral cavity, complex structure, and high price, etc., which limit the development of this technology.

Embodiment Construction

[0014] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further explained in conjunction with specific drawings.

[0015] Reference figure 1 , The maxillary body traction osteogenic device includes a fixed rod 1 and a guide rod 2 connected to the fixed rod 1. The fixed rod 1 is provided with fixing plates on both sides to facilitate the fixing of the fixed rod in human tissue.

[0016] The fixed board includes a straight board 4 and an arc-shaped board 3, and the side close to the guide rod 2 is set as an arc-shaped board 3. Both the straight board 4 and the arc board 3 are provided with mounting holes.

[0017] Due to the simple overall structure and ingenious design, a straight plate on one side is set to fix the fixed plate in the human tissue, and the arc plate on one side is matched with the guide rod to apply force to the maxillary traction osteoblast. The structure is sim...

Abstract

The invention discloses a traction bone forming device for a maxilla body. The traction bone forming device comprises a fixing rod and a guide rod connected with the fixing rod, wherein fixing plates are arranged on two sides of the fixing rod and used for enabling the fixing plate to be fixed in the human tissue conveniently. Each fixing plate comprises a straight plate and an arc plate which is arranged on the side of the fixing plate close to the guide rod, and installation holes are arranged on the straight plate and the arc plate. The traction bone forming device for the maxilla body is simple in integral structure and ingenious in design. The straight plates arranged on one sides fix the fixing plates into the human tissue, and the arc plates and the guide rod are matched mutually to exert acting force on the traction bone forming device for the maxilla body. Additionally, the traction bone forming device for the maxilla body has the advantages of being simple in structure and long in service life, changing the fixing mode and reducing wounds.

Description

Technical field [0001] The invention relates to implantation equipment, in particular to a maxillary body traction osteogenic device. Background technique [0002] Distraction osteogenesis is mainly a method of autogenous bone lengthening. Its completion is accompanied by the formation of callus repair. The callus is compressed and elongated. Due to the extension of the callus, new bone is also formed, and the new bone is in After formation, the body will not have the risk of resorption like the grafted bone, nor will it have a rejection reaction to the patient's body like the titanium mesh. This technique has an advantage that other techniques for repairing bone defects cannot match. Therefore, distraction osteogenesis has developed rapidly in recent years and has gradually been valued by doctors in Linkang. [0003] At present, most of the existing distraction osteogenerators for reconstructing the anterior maxillary defect at home and abroad are suitable for linear bone tractio...
