Embodiment Construction

[0017] In order to facilitate those skilled in the art to better understand the essence of the present invention, the specific embodiments of the present invention are described in detail below.

[0018] like Figure 1-5 As shown in the figure, the present invention customizes the osteotomy orthopedic guide plate, and its bone contacting working surface 1 is fitted with the bone surface, or a part of the bone that contacts with it can be embedded in the guide plate ( image 3 ), its outer surface 14 is determined by the thickness required for each position of the contact surface with the target bone, each side surface 3 of the guide plate is controlled by the arc of the bony prominence mark, and each side is aligned with the bony prominence mark to prevent the osteotomy guide from being placed The position is wrong; the middle part of the guide plate is provided with a number of osteotomy grooves 2, the osteotomy groove 2 can be used for the oscillating saw or the wire saw to ...

Abstract

The invention discloses an individual customized bone-cutting shape-righting guide plate. The bone-cutting shape-righting guide plate is characterized in that the working face of the bone-cutting shape-righting guide plate is attached to the bone surface, or a skeleton and the part in contact with the skeleton can be embedded into the guide plate, the outer surface of the guide plate is determined by the thickness required by all positions of the surface in contact with a target bone, and all the sides of the guide plate are controlled through arcs of apophysis marks and are made to be aligned with the apophysis marks. A fabrication method includes the steps of modeling the target bone through a reverse engineering technology to obtain a digital model of the skeleton, and measuring the position for bone cutting and shape righting, the bone cutting angle, and the plane where the angle is located; designing characteristics of all sides, bone cutting grooves, through holes, foramen lacerums and rounded angles of the guide plate in sequence through the bone cutting parameters, and performing 3d printing finally. The bone-cutting shape-righting guide plate has the advantages of being high in accuracy, simple and practical, rapid in mold forming and wide in application range.

Description

technical field [0001] The invention relates to the field of computer-aided modeling, in particular to the digital modeling of an individualized customized osteotomy orthopedic guide plate and a rapid prototyping method thereof. Background technique [0002] At present, the industrial revolution of 3D printing technology is in the ascendant, and the clinical application of 3D printing osteotomy guide is still in the laboratory stage. There are three main reasons that restrict the clinical application of this technology: 1. Accuracy, the clinical requirements for osteotomy accuracy are high, if the deviation is relatively high 2. Generally, the design is unreasonable, and there are not many problems to consider. The structure is too simple, and the clinician cannot install it correctly and quickly, which leads to the need for fluoroscopy to determine the plane, and the preoperative plan is not fully developed. As well as the advantages of 3D printing, it is necessary to desig...
