Solutions for Advanced Medical Applications

  • •    In the realm of Minimally Invasive Surgery (MIS), precision is paramount. Surgical instruments navigate tight spaces, making their way to the target site within the human body. While traditional methods and robot-assisted surgeries like the da Vinci Surgical System have served us well, they sometimes face limitations in flexibility and operational precision

  • •    Enter continuum robots—featuring a structure capable of continuous bending, they can adeptly maneuver around obstacles, emerging as an excellent choice for MIS. NOKOV's motion capture technology plays a vital role in the development of these robots by:

  • •    Creating dynamic models, analyzing modal frequencies, and assessing vibration modes for elastic material structures.

  • •    Capturing the trajectory of continuum robots to serve as a reference, allowing for accurate performance evaluation against planned paths.

Solutions for Advanced Medical Applications

Surgery navigation hinges on two components: the precision of NOKOV optical motion capture cameras and surgical instruments equipped with navigation markers. The motion capture cameras meticulously track the three-dimensional positions of these markers, providing surgeons with real-time spatial coordinates and orientation data. Integrating this information with preoperative imaging, surgeons gain enhanced visualization for navigational guidance.

NOKOV Optical Motion Capture System Features

•    High-precision Positioning

In surgery navigation, every millimeter counts. NOKOV's high-precision motion capture system, with accuracy up to 0.1mm, allows for swift and precise location of pathological areas, reducing surgery time and minimizing invasiveness—ultimately leading to better patient outcomes.

•    Adaptability in Surgical Settings

Tailored to meet the needs of various surgical scenarios, our system offers flexible lens configurations to overcome environmental constraints such as space limitations and equipment interference. Our calibration-free lens options provide a seamless, plug-and-play experience.

Surgery Navigation Scenario Examples
  • Robot-Assisted Surgery

    Real-time positioning of surgical robots is achieved through our optical navigation system, facilitating movement that closely follows preoperative plans.

  • Neurosurgery

    We enable precise location and tracking of anatomical structures, aligning them with preoperative imaging to assist in real-time instrument navigation.

  • Radiation Therapy

    Radiation Therapy

  • Orthopedics – Joint Arthroplasty

    Our system tracks and records bone structures, aiding in the precise positioning and alignment of implants, as well as guiding the angle and depth of cutting tools.

  • Spinal Surgery

    Combining tracking data with preoperative images, we enhance visualization and navigation during intricate procedures such as pedicle screw placement.

  • Augmented Reality (AR) in Surgery

    Augmenting traditional procedures with AR technology, we provide surgeons with a visual overlay of internal structures, enriching tool tracking capabilities.

  • ENT or FES Surgery

    Real-time tracking of surgical instruments helps avoid critical structures such as the optic nerve during sinus surgeries.

  • Dental Surgery

    We offer enhanced visualization for accurate implant positioning, helping maintain correct drilling angles while avoiding sensitive areas like the mandibular nerve.
