Problems solved by technology
However, due to the general anesthesia and passive position of the patient during the operation, it brought certain difficulties to the surgeon during the operation for bone extraction.
Generally, two to three people are required to perform bone extraction, and one person is responsible for maintaining the patient's position full-time, resulting in a waste of personnel

Embodiment
[0031] Embodiment: a kind of fixation device for taking fibular bone in mandible repair operation, its structure is as follows Figure 1-3 shown, including:
[0032] Bottom plate 11;
[0033] The left side of the base plate 11 is fixedly connected with a base 13, and the upper and lower sides of the base 13 are respectively fixedly connected with a lateral reciprocating mechanism 12; the lateral reciprocating mechanism 12 has a slider, and the slider is fixedly connected with a Ankle positioning plate 14 .
[0034] According to different needs, the lateral reciprocating mechanism 12 can be devices such as oil cylinders, linear slides or telescopic rods.
[0035] In the present invention, the lateral reciprocating mechanism 12 is preferably a lead screw type linear slide table, the slider of the lead screw type linear slide table is fixedly connected with the ankle joint positioning plate 14, and the ankle joint positioning can be realized through the rotation of the lead scr...

Description
technical field [0001] The invention relates to the technical field related to medicine, in particular to a fibula bone harvesting and fixing device used in mandibular repair surgery. Background technique [0002] The mandible is the only movable facial skull, which constitutes the lower third of the face. It is the supporting structure of important tissues such as teeth and tongue. It can cause bone defects in the maxillofacial region, which brings inconvenience to the shape and function of the patient, making it very painful. Therefore, the repair of the mandible is particularly important. The fibular flap has the advantages of sufficient bone mass and reliable blood supply, and has become a more commonly used method for repairing mandibular defects in clinical practice. However, due to the general anesthesia and passive position of the patient during the operation, it brought certain difficulties to the surgeon during the operation for bone extraction. Generally, two t...
