Problems solved by technology

In some traditional operations, the lesion cannot be observed directly with the naked eye (such as minimally invasive surgery or non-invasive surgery without surgery), or it is inconvenient to observe with the naked eye (such as brain neurosurgery), and doctors can only observe the lesion with the naked eye. image, place the surgical instrument at the target position based on experience, the error between the surgical device and the location of the lesion caused by this method will delay the operation time and affect the quality of the operation, especially this error sometimes brings patients unnecessary pain and injury

Abstract

The present invention is navigation system and method backing up several modes. The navigation system includes fixed imaging equipment, tracking system, surgical operation equipment, sick bed, calibrating pin, calibrating mold and navigation software. It has at least one tracer constituting the world coordinate system, one surgical operation equipment tracer as the surgical operation equipment coordinate system, one sick bed tracer constituting the sick bed coordinate system, one characteristic point set I and one characteristic point set II set inside and outside the calibrating mold separately. After calibration, the disease focus image and the surgical operation equipment are shown in the same coordinate system. The present invention may be used widely in the navigation course of different surgical operations.

Description

technical field [0001] The invention relates to an operation navigation system and a navigation method, in particular to a navigation system and a navigation method supporting multiple modes. Background technique [0002] The surgical navigation system is guided by the image formed by medical imaging equipment (including magnetic resonance imaging equipment, computerized tomography equipment (CT), C-arm, X-ray equipment, ultrasonic imaging system, etc.), and uses a tracking system to measure the position of surgical instruments. position, so that the three-dimensional image of the lesion and the virtual surgical instrument can be fused and displayed on the screen, helping the doctor to accurately locate the position of the lesion and the surgical instrument, and observe the organs and tissues around the lesion, helping the doctor avoid important organs and tissues, Safely bring surgical instruments to their intended location so that treatment can be completed. Surgical navi...
