Embodiment

[0026] Embodiment: A kind of 3D printing fibular osteotomy device, such as figure 1 shown. The device includes a guide plate 1, and the two ends of the guide plate are respectively provided with half ring hoops 2 correspondingly. The structure of guide plate 1 is as follows figure 2 , 4 As shown, the guide plate is an integrated metal guide plate, the guide plate extends along the direction of the fibula, and the cross section of the inner side of the guide plate is arc-shaped to fit the fibula 6 . The guide plate is provided with several elongated cutting guide holes 3 and a plurality of screw holes 5, and the screw holes are located in the middle of the cutting guide holes on both sides. Such as image 3 As shown, the inner surface of the half-encircling hoop 2 is provided with several tooth-shaped protrusions 4, and the tips of the tooth-shaped protrusions fit the surface of the fibula. Such as Figure 4 As shown, the half-encircling hoop is fastened with the end of ...

Abstract

The invention relates to a 3D printed fibula cutting device and a manufacturing and use method thereof, which can solve the problem that the fibula cutting operations are dependent on experience-based judgments of doctors, and then the operation risk is high at present. The 3D printed fibula cutting device includes a guide plate extending in the direction of a fibula; the guide plate is a metal guide plate; and a cross section of the inner side surface of the guide plate is an arc shape fitting the fibula, two semi-hoops are arranged corresponding to two ends of the guide plate; the semi-hoops are fastened on ends of side edges of the guide plate and clamp and surround the fibula; and a plurality of long bar-shaped cutting guide holes are formed in the guide plate. The 3D printed fibula cutting device is formed by 3D metal printing after computer simulation, and can meet the demands of fibula cutting guide plate accurate surgical operations; and the two ends of the guide plate are of tooth-shaped clamping structures, and through fastener fixing, the guide plate is fixed on the surface of the fibula by adoption of tapping screws, and then the stability of the guide plate is further improved.

Description

technical field [0001] The invention relates to a medical device, in particular to a 3D printing fibula osteotomy device and methods for making and using the same, which are applicable to the field of surgical operations requiring fibula osteotomy and shaping. Background technique [0002] In recent years, cases of jaw defects and deformities caused by factors such as growth and development problems, traffic accidents, and facial tumors are on the rise. The complexity and difficulty of surgery are also increasing, and the risk of surgery is also increasing. Oral and maxillofacial surgery for this kind of disease is a kind of more complicated surgery. At present, the steps of stomatologists in most hospitals in China are to observe the lesion area through the CT taken by the patient and pass Professional medical software reconstructs the 3D model and formulates a corresponding surgical plan, but this surgical plan is only a virtual plan designed by the doctor in the medical s...
