Description

Fibula cuts bone and rebuilds compound baffle

Technical Field

The utility model relates to the field of medical supplies, especially a fibula cuts bone and rebuilds compound baffle.

Background

In recent years, jaw bone defects and malformed cases caused by factors such as growth and development problems, traffic accidents, facial tumors and the like are in a rising trend, and most of stomatologists in domestic hospitals carry out the operation at present, wherein the steps of carrying out the operation comprise observing a diseased region through CT (computed tomography) shot by a patient, reconstructing a three-dimensional model through professional medical software, making a corresponding operation scheme, and then cutting normal bones in a human body to reconstruct jaw bones, and when the bones are selected, fibulas have sufficient bone mass and proper thickness and can provide a good foundation for later-stage planting repair; and has double blood supplies, easy to survive; the fibula cutting guide plate and the fibula cutting positioning device disclosed by Chinese patent No. CN207785234U are positioned between the fibula cutting guide plate and the fibula according to the above principle, but the bone cutting guide plate has a great disadvantage as shown in the attached drawing-3, when the fibula is cut off and reconstructed on the jawbone, a titanium plate is required to fix the position, when the titanium plate fixes the position of the fibula, the fixing hole on the bone cutting guide plate is randomly arranged and can not correspond to a nail channel on the titanium plate, at this moment just need punch on the fibula the secondary and fix the fibula, the secondary of fibula punches not only increased jaw and rebuild the operation time, has still reduced jaw and rebuild the precision of operation simultaneously, so how to solve this problem and become the direction that this technical field personnel studied.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's not enough, provide a fibula cuts bone and rebuilds compound baffle to solve the problem that proposes in the above-mentioned technical background.

The purpose of the utility model is realized through the following technical scheme:

the utility model provides a fibula cuts bone and rebuilds compound baffle, includes the baffle body, the baffle body is rectangular shape structure, and the cross-section of baffle body is the arc of laminating mutually with the fibula, is equipped with baffle fixed orifices and direction cutting sword groove on the baffle body respectively.

Furthermore, the positions of the guide plate fixing holes correspond to the positions of the titanium plate fixing holes one by one.

Further, the baffle body adopts 3D to print the shaping.

Further, the guide plate body is made of medical resin.

The utility model has the advantages that: the utility model provides a pair of fibula cuts bone and rebuilds compound baffle, the baffle fixed orifices can with the fixed orifices one-to-one on the titanium board, when the fibula was cut off and is rebuild on jaw, the titanium nail can be directly through the titanium board fixed orifices on the titanium board when installing the cutting fibula in the locating hole that leaves on the fibula, overcome the drawback that the secondary punched on the fibula when jaw is rebuild, not only improved jaw and rebuild the precision of operation, reduced jaw moreover and rebuild the operating time.
