Biovisus installs the core laparoscopic imaging system in each operating room, comprising rigid Laparoscopes (0°, 30°, and 45° viewing angles, 10 mm diameter), a 4K camera head, a high-intensity LED Light Source, and the 4K Image Processor. The system is mounted on a ceiling-suspended boom or a dedicated OR Trolley, with the 32-inch Medical Display positioned directly across from the primary surgeon.

The Laparoscopes feature sapphire optical windows with anti-reflective coatings, delivering a resolution of 200 line pairs/mm at the image plane. The 4K camera head uses three 1/3-inch CMOS sensors (native 3840 × 2160) with a prism-based color separation system. The camera head is autoclavable (134°C for 5 minutes) and weighs 180 g, with two programmable buttons for image capture and white balance. The Light Source delivers 800 W LED output through a 5 mm liquid light guide, with automatic light intensity adjustment based on camera exposure feedback.

The Image Processor applies real-time image enhancement: edge sharpening (configurable 0–100%), color saturation adjustment, and a fog reduction algorithm that compensates for the unavoidable condensation on the laparoscope tip upon abdominal entry. The system’s defogging mode temporarily increases light output by 50% for 10 seconds to warm the distal lens. The Medical Display is calibrated to the DICOM Grayscale Standard Display Function for consistent brightness and contrast.

Technical Note: The laparoscope’s optical system must be inspected for image clarity before each procedure; a cloudy image often indicates moisture between lens elements and requires immediate scope exchange. The 5 mm light guide’s end faces should be cleaned with 70% ethanol before each connection; a contaminated surface can reduce light transmission by 40%.

Biovisus configures the Ultrasonic Scalpel System as the primary energy device for dissection and hemostasis. The system comprises a generator, a handpiece with a 5 mm diameter, and a selection of blade tips (shears, hook, spatula) in 14 cm, 23 cm, and 36 cm lengths. The generator delivers 55.5 kHz mechanical vibration with an amplitude range of 40–100 µm, adjustable in 5-µm increments via the OR integration touchscreen.

The Ultrasonic Scalpel generates lateral thermal spread of <1.5 mm when used at the default power setting (level 3), validated histologically on porcine tissue. For gynecologic procedures, a dedicated tissue-sealing algorithm is activated: the generator modulates power based on real-time tissue impedance feedback, achieving vessel sealing up to 7 mm in diameter. The handpiece features a two-stage trigger: stage 1 activates the blade at low amplitude (coagulation-dominant), while stage 2 engages maximum amplitude (cutting-dominant).

The generator is integrated with the OR video system, displaying power level, activation time, and cumulative energy delivered on the auxiliary monitor. A foot pedal provides hands-free activation with two modes: continuous and pulsed. The Ultrasonic Scalpel’s blade is single-patient use, and a usage counter in the generator prevents reuse beyond the rated cycle limit. A smoke evacuator is activated automatically via a relay that detects generator activation.

Technical Note: The Ultrasonic Scalpel’s blade temperature can exceed 200°C during prolonged activation; a cooling period of 30 seconds is recommended after 20 seconds of continuous use to prevent adjacent tissue damage. The generator’s tissue-feedback algorithm should be recalibrated annually using a standardized tissue phantom; drift in impedance measurement may affect sealing reliability.

Biovisus supplies a comprehensive set of Laparoscopic Instruments, including graspers (traumatic and atraumatic), dissectors, scissors (curved and straight), needle holders, and clip appliers. All instruments are 5 mm or 10 mm diameter, 33–45 cm working length, with insulated shafts and rotatable handles. The handles are ergonomically designed with a ratchet mechanism for sustained tissue holding and a flush port for cleaning.

The instrument set is organized into procedure-specific trays: general surgery tray, gynecology tray, and bariatric tray. Each tray is RFID-tagged and tracked through the OR and central sterile supply department (CSSD). The system generates an alert if a required instrument is missing from the tray at the start of a case. High-value instruments (e.g., laparoscopic cameras, ultrasonic handpieces) are equipped with real-time location system (RTLS) tags with 1-meter accuracy.

The CO₂ Insufflator for laparoscopy delivers gas at 0.1–45 L/min with pressure control from 0–30 mmHg. The system is configured with a default abdominal pressure of 12 mmHg for general surgery and 15 mmHg for gynecology. A built-in gas warmer maintains CO₂ at 37°C ± 1°C at the point of insufflation. The insufflator’s automatic smoke evacuation mode periodically cycles gas to clear the operative field during energy device use.
The Irrigation Pump delivers sterile saline at 50–1,000 mL/min, with a pressure limit of 300 mmHg to prevent tissue damage. The pump’s tubing set includes a spike for 3 L irrigation bags and a Luer lock connection at the instrument end. For hysteroscopic procedures, the pump is configured with a dual-roller mechanism that provides pulsatile flow for enhanced distention.

Technical Note: The laparoscopic instruments’ insulation must be tested for dielectric integrity at 3,000 V before each use; a pinhole defect can cause alternate-site burns. The CO₂ Insufflator’s pressure sensor should be calibrated against a water manometer monthly. The irrigation tubing set’s maximum pressure rating is 600 mmHg; exceeding this limit may cause tubing rupture.

Biovisus integrates all components—imaging, energy, insufflation, irrigation—into a unified OR integration system. A central touchscreen (19-inch, wall-mounted) controls all devices, with each surgeon’s preferred settings stored as a profile. When the surgeon logs in via RFID badge, the system automatically configures light intensity, insufflation pressure, ultrasonic scalpel power, and display layout.

The OR Trolley consolidates the camera control unit, light source, insufflator, and ultrasonic scalpel generator into a single footprint. The trolley features a vertical column with 12 rack units (12U), cable management arms on both sides, and a side-mounted pole for the irrigation pump. The trolley’s base houses a medical-grade isolation transformer and a UPS providing 15 minutes of runtime for safe shutdown during power failure.

A ceiling-mounted auxiliary display (42-inch, FHD) is positioned for the surgical assistant and scrub nurse, mirroring the primary display’s content. The OR integration system supports picture-in-picture (PiP), allowing the surgeon to view laparoscopic video alongside preoperative imaging (CT, MRI) or the ultrasonic scalpel’s energy parameters. Video recording is initiated via a foot pedal, capturing the primary laparoscopic feed with a 2-second pre-event buffer.

Post-procedure, the system generates a structured operative report including video clips, energy usage statistics, and instrument utilization logs. The report is automatically linked to the patient’s EMR and to the surgical quality database. For gynecologic oncology procedures, the report includes lymph node count and specimen images captured via the laparoscopic camera.

Technical Note: The OR integration system requires a dedicated VLAN with Quality of Service (QoS) configured to prioritize video traffic; video latency must remain <33 ms (one frame at 30 fps). The Trolley’s UPS batteries should be load-tested quarterly and replaced every 3 years. Surgeon profiles must be updated whenever new devices are introduced to the OR.
