Fracture closed reduction navigation system and method

Abstract

The invention discloses a fracture closed reduction navigation system and method. The system includes a magnetic locator module and a computer software module; the magnetic locator module includes a magnetic locator sensor, a tracking source, and a probe; the computer software module includes : 3D reconstruction module, coordinate unification module and fracture reduction navigation module. The present invention obtains the spatial position in real time through the magnetic locator, reduces the number of X-ray irradiations received by doctors and patients, and reduces the injury of doctors and patients; the present invention collects the spatial data of broken bones in real time through the magnetic locator and renders them in the real-time mobile computer software module. The three-dimensional fracture model can monitor the position of the broken bone in real time, and the reset navigation display is more intuitive; the present invention can fully combine medical image information, spatial positioning technology and three-dimensional visualization technology, and can improve the accuracy and efficiency of reset.

Description

technical field [0001] The invention relates to the technical field of medical assistance, in particular to a fracture closed reduction navigation system and method. Background technique [0002] Fracture refers to the complete or partial break of the continuity of bone structure, which is a common trauma in life. The normal anatomical model of fracture patients is destroyed, which affects the function of limbs and brings great inconvenience to life. The treatment of fractures is usually through fracture reduction. Doctors generally perform reduction in the following ways: (I) manual reduction based on anatomical experience only; (II) manual reduction of fractures under X-ray fluoroscopy; (III) surgery to repair the fracture site. Perform internal fixation. Manual reduction based only on the anatomical structure poses a huge challenge to doctors, and it is very easy to cause other iatrogenic injuries such as failure of reduction. Only two-dimensional perspective informati...

Problems solved by technology

Manual reduction based only on the anatomical structure poses a huge challenge to doctors, and it is very easy to cause other iatrogenic injuries such as failure of reduction

Only two-dimensional perspective information is provided based on X-ray fluoroscopy, and there are problems such as loss of three-dimensional longitudinal information and image distortion. It cannot fully reflect the three-dimensional space information of the fracture and the mutual positional relationship of each fracture section, and cannot accurately evaluate the reduction during the reduction process. Images of tissues such as blood vessels, nerves, and muscles along the path

At the same time, the continuous use of X-rays will bring significant radiation damage to doctors and patients

Surgical internal fixation will cause secondary damage to the blood circulation of the fractured end, which is prone to postoperative infection. The healing rate of postoperative fractures is generally slower than that of naturally growing fractures with external fixation, and the postoperative nonunion rate is also higher.
