Embodiment 1

[0034] see figure 1 , is a schematic flowchart of a matching method of a medical bone plate in a specific embodiment of the present invention.

[0035] The matching method of the medical bone plate of embodiment 1 comprises the following steps:

[0036] S1: the step of obtaining the 3D data model of the patient's skeleton;

[0037] Specifically in this embodiment, 1) first scan the part to be fixed of the patient's skeleton at multiple angles to generate 3D point data; wherein, the part to be fixed of the patient's skeleton is generally diagnosed by a professional orthopedic surgeon Select the area and range of the part to be fixed. Wherein, scanning can be conventional CT scanning, obtains 3D point data after scanning; In the basics, according to the triangulation algorithm, the part of the patient's bone to be fixed is processed into a triangular mesh; the smaller the side length of the triangular mesh is set, the higher the simulation accuracy is, and the obtained surfac...

Embodiment 2

[0056] The matching method of the medical bone plate in Embodiment 2 also includes the above-mentioned steps S1-S4, and the only difference from Embodiment 1 is that the calculation method of MPI is different.

[0057] In the S3 step of embodiment 2, the computing method of MPI value is: see Figure 4 , according to the 3D surface data of the part of the patient's bone to be fixed, obtain the finite vertex coordinates of its triangular mesh, and set the vertices as D (1-n) ; Obtain the finite vertex coordinates of the triangular network of the bone-attached surface of the bone plate according to the triangular mesh algorithm, and set the vertices as C (1-n) ; Similarly, the smaller the set grid, the more the number of vertices, the more accurate the result, but the same amount of calculation will be greatly increased. Specifically, in this embodiment, the side length of the triangular mesh can be set to 0.1 mm to 1.0 mm;

[0058] Count each point C (1-n) The corresponding v...

Embodiment 3

[0062] Embodiment 3 provides a matching system for a medical bone plate, the matching system runs the matching method of the above-mentioned embodiment 1;

[0063] The matching system includes:

[0064] A module for obtaining a 3D data model of a patient's skeleton;

[0065] A module for accessing the data model of the bone plate; and

[0066] The matching module is used to sequentially match the bone-attached surface of each bone plate with the part of the patient's bone to be fixed, and select the most matching bone plate and its best relative position.

Abstract

The invention relates to a matching method and a matching system of a medical bone fracture plate and a matching device adopting the matching system. The matching method comprises the steps of obtaining a 3D data model of a bone of a patient, and calling the data model of the bone fracture plate from a bone fracture plate database; sequentially matching the bone attaching surface of each bone fracture plate with the to-be-fixed part of the bone of the patient, and selecting the most matched bone fracture plate and the optimal relative position of the bone fracture plate. According to the matching method of the medical bone fracture plate, the medical bone fracture plate with the optimal matching degree can be obtained in advance in a software calculation mode, and great convenience is brought to orthopedic clinicians; compared with the prior art that orthopaedic clinicians judge through naked eyes and experience, huge technical progress is obtained; furthermore, the unified universal quantitative indexes for medical bone fracture plate matching performance detection facilitate product evaluation, and the clinical use safety is greatly improved.

Description

technical field [0001] The invention relates to a matching method of a medical bone plate, a matching system thereof, and a matching device using the matching system, and belongs to the field of orthopedic matching algorithms. Background technique [0002] Bone plate is the most commonly used fracture internal fixation device in orthopedics. Since Hansmann (1866) first used bone plate to treat fractures, after more than 100 years of development and innovation, especially as the internal fixation concept of AO / ASIF changed from strong mechanical internal fixation to biological internal fixation, bone plate internal fixation Significant changes have been made in materials, manufacturing techniques, treatment techniques and treatment concepts. The material of the bone plate is also converted from the original stainless steel to titanium alloy or pure copper, and the types of the bone plate are also varied. According to the internal fixation method, there are tension band plat...
