SPECTRA NAVIGATION · MICROSURGERY
Spectra NavigationIntelligent Microsurgical Navigation System
Designed for deep-field visualization and quantitative guidance in microsurgery, the system integrates split-path stereoscopic imaging, miniature instrument tracking, and dynamic registration into one intraoperative platform.
01 · Clinical Need
Microsurgery lacks a quantitative reference for deep anatomy
The relative positions of lesion boundaries, instrument tips, and critical anatomy are difficult to judge directly. As procedures move deeper and toward smaller structures, reliance on individual experience increases, along with training time and variability in risk.

0.78per 100,000 people
The supply of specialists cannot expand quickly, increasing the value of navigation for decision support and shorter learning curves.
Clinical and market figures should be published with their definitions, reference year, indication scope, and public sources.
02 · Limits of Existing Solutions
Millimeter-scale navigation creates both scale and workflow mismatches in the microscopic field
Conventional navigation is generally designed around rigid bony fixation, large reflective markers, and an open field. Microsurgery requires smaller tracking components, higher localization accuracy, and robustness to occlusion, glare, bleeding, and soft-tissue deformation.
The microscopic field changes the basic conditions for navigation
Existing systems typically depend on rigid anatomy, large markers, and one-time registration. In the microscopic field, instrument tips, working space, and recognizable features all become smaller while soft tissue continues to deform. Navigation must therefore maintain a trustworthy reference continuously rather than localize only once.
2–10 mm
Registration remains too coarse
The effective field and critical structures in microsurgery are often only millimeters or smaller, making conventional navigation error unsuitable for fine manipulation.
20–100 mm
Tracking markers are too large
Large reflective markers occupy working space, obstruct the view, and alter the feel and inertia of delicate instruments.
Dynamic soft tissue
The intraoperative environment keeps changing
A small field contains few usable features, while tissue deformation and fluid reflections can quickly invalidate a one-time registration.
03 · Product Concept
Turn what cannot be seen into actionable intraoperative measurements
The system provides depth, boundary, distance, and risk cues around the surgeon's active microscopic workflow, keeping preoperative imaging, instrument position, and the intraoperative view linked.
WITHOUT NAVIGATION · 01
Deep structures remain unseen and decisions depend on individual experience
- Tissue boundaries lack quantitative references, making under-resection and over-resection difficult to assess
- Surgeons must integrate multiple information sources themselves, increasing cognitive load
- Training and supervision require extensive case experience
WITH SPECTRA · 02
Critical structures are quantified and updated with instrument position in real time
- Displays the relative position of the instrument tip and lesion boundary
- Overlays the preoperative model onto the intraoperative microscopic view
- Provides a consistent reference for decisions, documentation, and review
The objective is concrete: bring boundary, distance, and risk cues into the current view without disrupting the surgeon's core operating habits.Product value still requires continued validation in real clinical workflows, against defined baselines, and through surgeon feedback.
04 · Core Technology
Three technologies address field visualization, instrument tracking, and continuous model alignment
Visualization reconstructs the 3D surgical field, precision tracking localizes the instrument tip, and intelligent registration updates the coordinate reference as tissue and the field change. These capabilities connect along a single navigation chain.
VISUALIZATION · 01
Visualization: split-path stereoscopic microscopic imaging
The three images show how visualization is implemented: coaxial visible and near-infrared acquisition, a validation prototype that establishes 3D metrology, and final integration with an operating microscope.
- Visible and near-infrared light share one optical path for simultaneous field visualization and tracking-signal acquisition.
- Stereo vision provides the 3D measurement foundation, converting microscopic images into depth and relative-position information.
- Once integrated with the microscope, the system supplies stable observations for instrument tracking and dynamic registration.
Intelligent Registration
Instrument Tracking
High-precision Reconstruction
The microscope platform combines imaging and metrology, preserving the live surgical field while providing structural, depth, and relative-position references.
PRECISION · 02
Ultrafine optical fibers enable continuous instrument-tip tracking
Ultrafine optical fibers are embedded in microsurgical forceps, scissors, and related instruments to add active tip-tracking signals while preserving familiar dimensions, weight, and handling.

INTELLIGENCE · 03
Dynamic registration maintains a reliable reference at microscale
In robotic R&D validation, the system created an approximately 2 mm cranial window in mouse skulls averaging about 0.3 mm thick. The central capability is maintaining the preoperative plan, live view, and instrument position in one coordinate relationship to support high-precision operation.

01
Establish initial alignment
Extract constraints from recognizable structures such as vessels and bone-surface texture to align the preoperative model with the intraoperative view.
02
Continuously evaluate deviation
Under a small field, occlusion, glare, and tissue change, the system continuously checks whether the current reference remains reliable.
03
Update coordinates online
Dynamic landmarks update relative positions and return the instrument trajectory, model, and live image to a common spatial relationship.
These results demonstrate R&D-stage system capabilities. Medical use, performance claims, and clinical approval status remain subject to subsequent validation and public regulatory documents.
05 · Product System
The product is an integrated intraoperative hardware-software system
The system combines a 3D navigation workstation, split-path stereo operating microscope, and trackable fiber-optic instruments. Dynamic registration, AI recognition, and intraoperative visualization connect all three components.

IP PORTFOLIO
The team has filed or secured nine patents covering navigation, registration, instrument tracking, and surgical robotics
The Japanese application for a navigation system, algorithm, and instruments, together with the Chinese application for a 3D calibration board and performance-evaluation method for stereo microscopic imaging, are most closely aligned with the current product. The remaining patents reflect prior technical work; ownership, licensing scope, and freedom to operate require item-by-item confirmation during investment and partnership due diligence.
