Key Investor Signals
Cir.Log is live at 4 hospitals across Germany, Austria and Switzerland
Cir.Log is deployed at Sozialstiftung Bamberg, St. Josefs Hospital Dortmund-Hörde, Kardinal Schwarzenberg Klinikum in Austria and, since September 2026, in a 12-month pilot at Universitätsspital Basel.
Cir.Log integrates directly with NEXUS EuroSDS software
NEXUS documents a direct Cir.Log–EuroSDS integration: staff can launch the camera from EuroSDS, view AI counting results and mark confirmed instruments as packed.

Product
Cir.Log is a retrofit camera mounted above hospital sterile-processing packing tables. It recognises and counts instruments locally, checks each tray against its packing list and records the process with images. It connects to existing hospital sterile-processing software, including NEXUS EuroSDS.
Recognises instruments without tags
Cir.Log identifies instruments by shape and appearance at item-number level, without adding barcodes, RFID tags or other markers. Fraunhofer says it already recognises more than 10,000 surgical instruments.
Checks and records each tray
Cir.Log compares recognised instruments with the tray’s packing list in real time, flags missing or incorrect items and records the process with images. Confirmed items can be marked as packed directly in EuroSDS.
Automates loan-set intake
It scans supplier delivery notes and instrument markings to create packing lists and master data for loan or repaired instruments. enamentis reports up to 90% less manual booking.
Market Overview
Sterile processing is a high-volume, safety-critical hospital workflow. At Charité alone, more than 14 million surgical instruments are reprocessed each year, while a single tray can require staff to identify and pack up to 160 items. Missing or incorrect instruments can create rework and operating-room delays.
Germany recorded 16.31 million inpatient operations in 2024, underscoring the scale of surgical workflows that depend on instrument reprocessing. Hospitals already buy tracking and sterile-supply software, while most incumbent systems rely on barcodes or RFID, leaving tray assembly largely manual.
Charité reprocesses around 14 million surgical instruments each year.
A single tray can contain up to 160 different surgical instruments.
Germany recorded 16.31 million inpatient operations across hospitals in 2024.

Comparable Outcomes
Censis Technologies
Censis built surgical-instrument tracking and workflow software for sterile-processing departments, covering tray assembly, sterilisation and inventory management. Fortive acquired Censis in 2019 for an undisclosed amount. Censis said its software was deployed in 1,000+ hospitals across the US, Canada and Australia.
RF Surgical Systems
RF Surgical developed radiofrequency-tagged surgical sponges and a detection system to help operating teams identify retained items before wound closure. Medtronic acquired RF Surgical Systems in August 2015 for total consideration of approximately $240 million.
