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 redu

Abstract

The invention discloses a navigation system and method for closed reduction of a fracture. The system comprises a magnetic locator module and a computer software module; the magnetic locator module comprises a magnetic locator sensor, a tracking generator and a probe; the computer software module comprises a three-dimensional reconstruction module, a coordinate unification module and a fracture reduction navigation module. The navigation system and method for the closed reduction of the fracture have the advantages that the spatial position is acquired in real time through magnetic locator, and the frequency of doctors and patients receiving X-ray irradiation is reduced, thereby reducing the damage to the doctors and the patients; spatial data of a broken bone is collected in real time through the magnetic locator, and a three-dimensional fracture model rendered in the computer software module is moved in real time, so that the position of the broken bone can be monitored in real time,and the reduction navigation display is more visual; medical image information, a spatial positioning technology and a three-dimensional visualization technology can be fully combined, so that the reduction precision and efficiency can be improved.

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...
