Abstract

A navigation system for intracerebral hemorrhage puncture surgery based on medical image model reconstruction and localization is disclosed in the embodiment of the invention, Positioned navigation system for intracerebral hemorrhage puncture surgery, including hosts, AR device and naked-eye 3D display device, The host computer receives the medical CT/MRI data of patients with intracerebral hemorrhage, reconstructs the model of multi-group patients with intracerebral hemorrhage, processes the model butt joint, obtains the three-dimensional virtual model of patients' skull and hematoma, and displays the three-dimensional virtual model on the naked eye 3D display device. The host computer receives the medical CT/MRI data of patients with intracerebral hemorrhage. According to the 3D virtualmodel and the angle depth information, the host computer simulates the operation navigation and connection to import the AR device. AR devices are used for feature point detection, spatial registration between virtual hematoma and real hematoma, real-time catheter tracking, holographic display of virtual hematoma and virtual catheter, voice and somatosensory interaction with physicians. The embodiment of the invention can reduce medical cost and provide human-computer interaction function.

Description

technical field [0001] The invention relates to the technical field of surgical navigation, in particular to a cerebral hemorrhage puncture surgical navigation system based on medical image model reconstruction and positioning. Background technique [0002] The onset of cerebral hemorrhage is dangerous, and the condition changes rapidly. Nearly half of the deaths occur in the acute stage, especially within 48 hours of onset. Patients need to be rescued by the nearest hospital. However, most primary hospitals in my country have relatively limited equipment and technical conditions, and the level of surgical treatment is not high. In clinical work, minimally invasive puncture surgery for cerebral hemorrhage often occurs when the position of the catheter is shifted, the surgical effect is not good, and the risk of death of the patient is even increased. Therefore, further in-depth research is urgently needed to develop a device system that improves the accuracy of minimally inv...
