Embodiment Construction

[0043] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0044] A method for designing an internal fixation system for the posterior column of the acetabular posterior wall, using the following steps,

[0045] Step 1: Select 100 adult complete pelvic CT data of males and females, the average age of males is 48.5 years old, and the average age of females is 50.8 years old, and pelvic acetabular fractures, tumors and other lesions are excluded, and the three-dimensional model of the pelvis is reconstructed by computer , in this embodiment, carry out three-dimensional reconstruction by importing Mimics software;

[0046] Step 2: Measure the arc length AB from the highest point A of the acetabular rim to t...

Abstract

The invention provides a method and an apparatus for designing acetabulum back-wall back-column bone fracture internally fixing system. The method comprises the following steps: choosing a proper amount of pelvis CT data for three-dimensional modeling; measuring the arc length of each acetabulum from its highest point to the lowest point; using the pelvis with an arc length close to the average arc length of the acetabulums as a standard pelvis; converting the standard pelvis into a point cloud file; conducting triangle gridding to the point cloud file; and using the reverse engineering technique to simulate surface anatomical morphology of the acetabulum back-wall back-column; and according to the characteristics of an acetabulum back-wall back-column bone fracture in clinics, designing two steel plates of different shapes with one suitable for high-level acetabulum back-wall back-column bone fractures and the other for non-high-level acetabulum back-wall back-column bone fractures. The main parts of the steel plates are big in size and have a plurality of screw holes so that a patient could choose the suitable screw holes for bone fracture fixation after a surgery. The locking screw holes at the outer sides of the steel plates are small in diameter and vary in direction so that small bone fracture blocks at the edges could be fixed conveniently.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a design method and device for an anatomical internal fixation system for fractures of the posterior column of the acetabular wall. Background technique [0002] The main internal fixation methods for posterior column fractures of the posterior wall of the acetabulum include screw fixation, reconstruction plate combined with lag screw fixation, single plate and double plate fixation, acetabular three-dimensional memory internal fixation system, etc. But all have their limitations, such as poor fixation strength, poor compliance, multiple pre-bends, and difficulty in fixing fractures of the posterior wall of the acetabulum. Therefore, it is necessary to provide a novel internal fixation system for fractures of the posterior column of the acetabular wall. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes a design method ...
