A surgical navigation system is an image-guided intraoperative location system, whose main function is to provide the surgeon with a real-time feedback of the location of the surgical instruments in relation to the anatomy of the patient.  Therefore, it helps the planning and execution of surgical procedures in the operating theaters, guiding surgical instruments such as the electric scalpel. There are two types of navigation system: Optics and electromagnetic, both provide combined flexibility and efficiency in a space-saving design in the OR.

Today there is an increase in the demand for non-invasive surgeries, with reduced hospital stays, little pain for the patient and rapid wound healing. This has led to a considerable increase in demand for surgical navigation systems.

Parts of a surgical navigation system

A surgical navigation system is composed of several instruments that are connected to screens by sensors with imaging methods. These systems offer optical tracking capabilities as well as integration with external devices such as microscopes and ultrasounds.

This modern medical device consists of software that allows the deployment of images in two and three dimensions, an intraoperative localization instrument, and a method of recording between the images and the operating room environment. In the most common, infrared cameras can be found to locate the instruments, while other models employ an electromagnetic field.

What is the function of a navigation system?

These optical surgical navigation systems are intended to help accurately locate anatomical structures in open or percutaneous procedures. They are now considered an integral part of computer-assisted surgery. That is, they provide surgical procedures based on digital imaging technology and give surgeons the opportunity to perform preoperative planning and precise handling of instruments during operation.

In this sense, surgical navigation systems work with conventional imaging techniques such as CT scans or MRI, and can be used in procedures such as:

  • Biopsy.
  • Catheter placement.
  • Tumor resection.
  • Decompression of the column.
  • Pelvic or spinal fixation.
  • Treatment for spinal or sacral trauma.
  • Deep brain stimulation electrode positioning.

How does an optical surgical navigation system work?

An optical surgical navigation system works based on the principle of stereoscopic vision with high precision. Surgical navigation system equipment mainly includes Polaris navigation systems, micron navigation systems, and others.

These systems are also used in guided neurosurgery. Polaris surgical navigation systems provide position information on the monitor using 3D measurement navigation technology using a positioning laser.

What do we offer you in Kalstein?

Kalstein is a company MANUFACTURER of medical and laboratory equipment of the highest quality and that have the most advanced technology at the best prices in the market, so we guarantee you a safe and effective purchase, knowing that you have the service of a solid company and committed to health. In this opportunity we present our innovative YR02143 electromagnetic navigation system assisted by computer, which has the following features:

  • It is widely used for surgical visualization, planning and navigation to help minimize iatrogenic trauma to surrounding brain tissue and reduce the risk of surgical complications in cranial procedures (such as cranial neurology and ENT surgery).
  • The advanced optical tracking system tracks real-time 3D position and orientation of active or passive markers attached to surgical tools, for exceptional accuracy (1.0 mm spatial resolution) and reliability.
  • The method of 3D simulation and modeling of anatomical structures in material (such as skin, skull, brain tissue or target injury) can be easily defined by surgical convenience.
  • With the navigation probe and advanced optical measurement technology built in, the surgeon can easily quantify the size and position of the lesions, then scientifically design the surgical approach.
  • The system provides operators with four navigation modes for comprehensive monitoring of the navigation process.
  • The intelligent software will help calibrate and compensate for unexpected changes in anatomical structure and brain change induced by removal of the intracranial lesion area.
  • The YR02143 navigation system can be operated with a surgeon mouse or a touch monitor mounted on the mobile cart or on the ceiling hanger arm.
  • The system automatically stores all patient image data and log information to allow the surgeon to quickly charge and continue surgical navigation against the unexpected power outage.
  • It can be used for all neurological and ORL surgeries, especially in deep intracranial lesions, small intracranial volume lesions, small-edge intracranial lesions and minimally invasive surgeries.
