Surgical positioning assembly and magnetic resonance compatible surgical navigation system

Abstract

The invention relates to a surgical positioning assembly and a magnetic resonance compatible surgical navigation system. According to the surgical positioning assembly and the magnetic resonance compatible surgical navigation system, a supporting frame can move at least in two degrees of freedom relative to the expected position of the body of a patient, so that the surgical positioning assembly can achieve conversion of at least two degrees of freedom, and the surgical implementation difficulty is reduced. In addition, according to another surgical positioning assembly, a coil generating a magnetic field is arranged in the expected position area of the body of the patient and connected with a magnetic resonance system to achieve radiography before and in the surgical process, so that thespatial position of a positioning target point is obtained in the surgery, radiography and target position positioning can be synchronously conducted, the surgical accuracy can be improved, the surgical infection risk is reduced, and the surgical time is shortened. The surgical positioning assembly and the magnetic resonance compatible surgical navigation system are suitable for implantation medical surgery or interventional medical surgery, especially implantation medical surgery or interventional medical surgery compatible with nuclear magnetic resonance.

Description

technical field [0001] The invention relates to a surgical positioning component and a magnetic resonance compatible surgical navigation system, belonging to medical surgical equipment. Background technique [0002] Magnetic Resonance Imaging (MRI) is a new imaging diagnosis technology applied in clinic in the 1980s. MRI is capable of multi-directional, multi-plane, multi-parameter imaging, has excellent soft tissue resolution and has precise geometric characteristics; compared with X-ray and CT, MRI has no ionizing radiation, and has no harm to patients and doctors. Compared with other imaging methods, due to the advantages of MRI in minimally invasive surgery, doctors and engineers decided to transplant robotic technology into MRI, which has the advantages of no radiation, multi-directional imaging, excellent soft tissue resolution, and precise positioning. MRI image-guided robot-assisted minimally invasive surgery, which has the advantages of long working hours and other...

Problems solved by technology

During the implantation operation, since there is cerebral fluid in the human head, and the human brain tissue is covered by cerebral fluid, when the IPG implantation operation is performed, when the brain shell is opened, a small part of the brain fluid will flow out of the brain. At this time, due to changes in the amount of cerebral fluid, the position of the brain tissue will shift, and the spatial position of the positioning target point will also shift. At this time, if the operation is still performed according to the previous contrast images, the implanted IPG cannot Accurately reach the positioning target point

[0004] In addition, the current positioning components are not compatible with the MRI room, and the IPG implantation operation needs to be performed in the MRI room, so that the patient is repeatedly pushed (pushed out) into the MRI room, which increases the risk of infection and delays surgery time
