3D printing guide board capable of controlling osteotomy depth for fibular flap shaping operation

Abstract

The invention provides a 3D printing guide board capable of controlling the osteotomy depth for a fibular flap shaping operation. The guiding board comprises a guiding board body, a plurality of location parts are arranged on the guiding board body, and each location part is composed of one or more location plates; the outer end surface of each location part is provided with a fibula osteotomy depth controlling groove and a fibula osteotomy direction controlling through groove, and the fibula osteotomy direction controlling through grooves are formed in the trend of the fibula osteotomy depthcontrolling grooves. The fibula osteotomy depth controlling grooves and the fibula osteotomy direction controlling through grooves which are formed in the guiding board can effectively control the osteotomy trend and depth, and therefore the vessel pedicle on the inner side of the fibula is not injured on the premise that it is ensured that the fibula is cut by a saw blade. Therefore, in the usingprocess of the guiding board, it is unnecessary to strip the vessel pedicle on the inner side of the fibula, blood supply to the fibula is effectively protected, the operation time is significantly shortened, and the efficiency of the fibular flap shaping operation performed by medical workers is improved.

Description

Technical field [0001] The invention relates to a 3D printing guide plate, in particular to a 3D printing guide plate with a controllable osteotomy depth for fibular flap shaping surgery. Background technique [0002] Vascularized free fibular flap transplantation is an important method to repair the defects of the upper and lower jaws. In fibula flap transplantation, three-dimensional segmental osteotomy, splicing and shaping of the fibula are required. Although there are some surgical guides to assist fibula osteotomy and shaping, they only guide in the direction of segmental osteotomy, so there are two problems: one is that in order to protect the vascular pedicle of the medial fibula during osteotomy, it is necessary Peel off the periosteum around the inner fibula osteotomy line, and place a stripper and other protective tools, which will cause the loss of blood supply to the fibular flap; second, the process of periosteal peeling will significantly extend the operation time...

Problems solved by technology

[0003] In order to solve the above existing problems in the prior art, the present invention aims to solve the problem that the osteotomy depth is not easy to control in fibula segmental osteotomy, and the medial fibula periosteum stripping causes the blood supply to decrease. A new type of personalized 3D printed fibula osteotomy is designed. bone guide
