Biovisus outfits every operation room with standard endoscopes: gastroscopes, colonoscopes, duodenoscopes and choledochoscopes.
Each device matches a modular imaging system of high-power LED light source, 4K image processor and 32-inch medical screen.

White light and narrow-band imaging help clearly distinguish mucosal textures.

Gastroscope: 9.8mm insertion tube, 2.8mm working channel, 210-degree bending range (90° upward, 120° downward)
Colonoscope: flexible stiffness tube, 13.2mm front tip, 3.8mm working channel
Duodenoscope: 100-degree side-view lens with elevator for accurate ERCP intubation
Choledochoscope: 3.5mm outer diameter for direct duct observation

500W LED light source runs at 5500K, brightness adjusted by 10% steps.
4K processor outputs 3840×2160 footage at 60fps; structural and color enhancement functions switchable through scope buttons.
32-inch IPS medical screen has 1500:1 contrast and 800 cd/m² brightness, calibrated weekly with standard color charts.

Technical reminders
LED light module lasts 40000 working hours; the system records runtime and sends replacement prompts at 35000 hours.
Check bending mesh for wear after 100 operations; broken mesh weakens bending precision.

Biovisus bundles CO₂ insufflator and irrigation pump into an all-in-one endoscopic auxiliary unit.
The CO₂ insufflator outputs heated CO₂ at 37°C, with adjustable flow ranging from 0.5 to 35 L/min. It features auto pressure limits of 15 mmHg for colonoscopy and 8 mmHg for gastroscopy.
The irrigation pump dispenses sterile water or saline from 50 to 500 mL/min. A foot trigger enables instant high-volume flushing to clear lumens quickly.

The insufflator connects to medical CO₂ tanks via dual-stage pressure regulators. Its pressure sensor achieves ±0.5 mmHg precision with response time under 100ms. Auto alternating inflation and pressure hold modes cuts gas consumption by 30% for long surgeries.

The irrigation pump links to the endoscope’s dedicated water channel. Adopting a brushless motor and peristaltic structure, it supports common disposable tubes and maintains 500 mL/min flow under 300 mmHg backpressure. The built-in warming compartment stabilizes fluid temperature at 37°C ±1°C to avoid patient hypothermia.

Both devices are installed on a specialized endoscopy trolley. The cart is fitted with lockable casters, height-adjustable monitor bracket and internal cable slots. It supports up to 120kg with a 2.0 safety coefficient, and the handle contains a 4-port USB charging hub for peripheral devices.

Technical Notes
Zero the insufflator’s pressure sensor against ambient pressure daily before use.
Irrigation tubing is for single-patient use only; reuse causes contamination and motor damage.
Secure trolley brakes during all examinations to avoid accidental displacement.

Biovisus designs duodenoscopes and choledochoscopes for complex biliary and pancreatic treatments.
The 4.2 mm working channel of the duodenoscope fits standard ERCP tools including sphincterotomes, guidewires, retrieval balloons and biliary stents.

Choledochoscopes deliver direct views of bile ducts for stone removal and stricture checks, usable through duodenoscope channels or percutaneous entry.

The duodenoscope elevator gets calibrated before every operation, moving 0–60 degrees with a fixed lock point at 30 degrees.
Its side-view optics work with a custom processor display setting optimized for ampulla viewing to tune brightness and contrast for angled sightlines.
A separate foot switch lets clinicians switch white light and NBI without releasing the scope handle.

The 3.5 mm outer diameter choledochoscope has a 1.2 mm inner channel compatible with 0.025-inch guidewires and 3 Fr stone baskets.
Its tip bends 90 degrees upward and downward via thumb control on the handpiece.
A unique processor imaging algorithm boosts lumen contrast to offset its narrow 80-degree field of view and dim bile duct lighting.

RFID tags fitted on the procedure cart track all ERCP attachments.
The system records batch codes, expiry dates and usage duration, and triggers warnings for expired tools.
After treatment, stock reports auto-generate restock requests once inventory drops below a three-day supply reserve.

Technical Notes
Lubricate duodenoscope elevator cables weekly with medical silicone oil; stiff movement signals corroded wire needing replacement.
Choledochoscope fiber bundles are delicate; storage coils must be no smaller than 20 cm across to prevent damage.

Biovisus enforces full standardized reprocessing steps for all reusable endoscopes.
Every exam room has an instant pre-clean station for wiping scope surfaces and flushing inner channels right after use.

Scopes move to central reprocessing zones inside sealed leak-proof transport bins.

Automated endoscope reprocessors deliver verified high-level disinfection with fixed cycles:
5-minute enzymatic wash at 35°C, 3-minute soap rinse, 5-minute peracetic acid disinfection at 25°C, 3-minute final water flush.
Machines record temperature, chemical strength and soak duration; cycles stop automatically if values drift over 5% from standards.

Post-cleaning scopes dry 15 minutes with HEPA filtered air (0.3μm filter, 99.97% filtration rate).
Scopes store upright in ventilated cabinets with steady HEPA airflow, positive internal pressure, and 15-minute interval temperature and humidity logs.

Built-in RFID logs each scope’s disinfection record; units held over 7 days get blocked from reuse until reprocessed again.

Monthly biological sampling flushes 10mL fluid through every channel for culturing, requiring colony counts below 10 CFU per channel.
Annual pressure decay leak tests run at 260 mmHg over 30 seconds to spot 25μm gaps; faulty scopes get isolated for repairs at once.

Technical Notes
AER concentration spectrophotometers calibrate monthly with standard solutions.
Storage cabinet HEPA filters swap every six months or when pressure loss rises 25% above original levels.
Pre-cleaning must start within 15 minutes post-operation; delays create biofilm resistant to standard high-level disinfection.

Biovisus runs a central endoscopy management system unifying booking, case records, image storage and pathology tracking.

Staff access it through a 55-inch screen at the nursing station and tablet devices fitted on each procedure trolley.
One login lets gastroenterologists check timetables, old records and launch imaging tools.

The scheduling tool estimates case length automatically using operation type and each doctor’s historical speed data.
Patient check-in pulls up past endoscopy files, pathology results and related scans instantly.

Key metrics get logged live during treatment: colon cecal intubation time, ERCP duodenal entry time, fluoroscopy duration and biopsy quantity.

All endoscopic photos and videos save as DICOM files on RAID 6 backup storage with a 10-year retention rule.
A neural network trained on 500,000 marked scope images auto-tags anatomical areas for each file.
Structured reports list operation info, ICD-10 coded observations, treatment steps and follow-up advice.
Files send straight to referral doctors’ electronic medical systems and patient online portals.

A quality dashboard compiles facility-wide data including adenoma detection rate, cecal success rate and adverse event frequency.
The gastroenterology quality panel analyzes this data every month.
For post-polyp removal monitoring, the system computes guideline-mandated revisit cycles and sends automatic alerts to patients and referring providers.

Technical Notes
Hospitals doing 10,000 procedures yearly need archive servers with at least 64GB RAM and 50TB storage.
The report tool works with noise-cancelling microphones for voice-to-text input in busy exam rooms.
Doctors need a minimum of 100 screening colonoscopies for their adenoma detection rate to carry reliable statistical meaning.
