Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to an orthopedic navigation device.

Background

In recent years, with the rapid development of orthopedic techniques, the difficulty and risk of surgery increase, and simultaneously, image-assisted and minimally invasive techniques become the main direction of orthopedic development. Under the condition, some medical instruments similar to an orthopedic navigation system are delivered by oneself, the system can greatly reduce the risks of complex orthopedic operations, and bring a new operation mode-visual surgical technology for the orthopedic operation technology, most of the existing orthopedic navigation devices are installed on a base with rollers for use, but the space of an operating room is limited, more instruments need to be used during the operations, and medical staff frequently walk and easily collide with the instruments to cause instrument damage, and after the bone positioning navigation is carried out on a patient, if the patient slightly moves, the deviation of the positioning is possibly caused, the deviation of the operation position of a doctor is caused, and the life safety of the patient is threatened.
