Multi-track (optical navigation system)

History

2025: Product Announcement

In mid-April 2025, Sechenov University introduced the first Russian optical navigation system Multitrek. It is designed to perform high-precision operations on the spine. On the basis of the Department of Topographic Anatomy and Operative Surgery of the University, a study of the accuracy of this navigation system during surgical interventions is being carried out.

According to the press service of Sechenov University, the navigation system "Multitrek" was developed by the group of companies "Gammamed" with the participation of the Research Institute of Nuclear Physics named after D.V. Skobeltsin, Moscow State University. M.V. Lomonosov and the support of the Fund for Assistance to the Development of Small Forms of Enterprises in the scientific and technical field.

The system is based on infrared cameras, which during surgery track the position of surgical instruments with an accuracy of a fraction of a millimeter. Navigation is based on CT and MRI scans of the patient preloaded into the system. Orientation in the operating wound is ensured by recording on individual points or a bone surface performed at the beginning of the operation.

The device includes infrared cameras, instruments with optical spheres reflecting the infrared signal, as well as a control unit with completely Russian-made software.

The study is carried out on anatomical material, previously digitized using computed tomography. During registration, the spine of a real patient is tied to its virtual model, built by the system based on data from preoperative neuroimaging.

Professor of the Department of Topographic Anatomy and Operative Surgery of Sechenov University Yuri Vasiliev pointed out that the results obtained during the study will make it possible to draw conclusions about the capabilities of the system in positioning metal structures used to fix the spine in determining the volume of resection of vertebral tumors, as well as compare Russian development with foreign analogues. For a patient with spinal pathologies, the precision of surgery is both faster rehabilitation and a chance for a high quality of life after surgery.
