Abstract

The invention discloses a 3D printed femoral head necrosis navigation template and a construction method thereof and use of the navigation template and construction method. The construction method comprises the following steps: acquiring and processing femoral head image data, reconstructing a femoral head three-dimensional model, positioning a target area on the femoral head three-dimensional model, digitally generating a virtual navigation template, and performing 3D printing on the navigation template to obtain a navigation base template which can be accurately matched with a femoral head greater trochanter area and a navigation tube with an optimal needle insertion angle and direction. The femoral head necrosis navigation template obtained on the basis of the three-dimensional reconstruction and 3D printing can be visually applied to operation navigation of an operation, effectively reduces radiation injuries and wounds to a patient, and is convenient for an operator to master, operate and perform technology promotion.

Description

technical field

[0001] The present invention relates to the technical field of a femoral head necrosis positioning and navigation device, in particular to a 3D printed femoral head necrosis navigation template and its construction method and application. Background technique

[0002] Avascular necrosis of the femoral head is a common clinical disease. There are many treatment methods for avascular necrosis of the femoral head. Among them, drilling and decompression of the femoral head was first used by the Germans to treat avascular necrosis of the femoral head. The early effect is remarkable. In theory , Reduce intraosseous pressure, rebuild blood circulation, restore blood flow to the femoral head, make dead bone tissue have the opportunity to contact living tissue, and promote the repair process. Core decompression in the treatment of early avascular necrosis of the femoral head has definite curative effect, which has been recognized by most clinical orthopedic surgeons. ...
