Priorto installs the Operating Table and Operating Light systems, configured for specialtyspecific requirements. The Operating Table features a fivesection carbon fiber top with 20 cm of longitudinal travel and Trendelenburg tilt of 30°. The Operating Light uses a LED array with a 300 mm light field, maintaining 160,000 lux at 1 m distance with a color rendering index (CRI) of 96. Both systems are integrated with the OR integration system, allowing table and light positions to be stored as presets for different procedures (e.g., laparoscopic cholecystectomy, total knee arthroplasty).

The Operating Table’s carbon fiber top is radiolucent over the entire surface, supporting intraoperative imaging without patient repositioning. The table’s height adjustment range (55–100 cm) accommodates surgeons of varying stature. For orthopedic procedures, a traction attachment is installed on the table’s distal end, calibrated to provide 50 kg of continuous traction force. The table’s hand pendant is configured with onetouch return to level position and an emergency stop button that halts all motion within 0.5 seconds.

The Operating Light is equipped with a sterilehandle mounted control that allows the surgeon to adjust intensity and focus without breaking sterility. A duallight configuration (two heads on a ceiling mount) is specified for large incisions, providing shadow reduction below 5%. For neurosurgery, a third light with a 150 mm field and 200,000 lux is added for deep cavity illumination. The light’s color temperature is fixed at 4,500 K, with a builtin camera recording the surgical field for teaching and documentation.

Technical Note: The Operating Table’s carbon fiber top has a weight limit of 350 kg when evenly distributed; for bariatric patients, a reinforced top rated to 450 kg is available. The Operating Light’s LED modules have a rated lifespan of 60,000 hours; the system automatically logs cumulative usage and alerts biomedical engineering at 50,000 hours.

Priorto deploys the Anesthesia Machine, configured with dual vaporizers (sevoflurane and desflurane), a circle breathing system, and a 15inch touchscreen display. The machine is integrated with the Patient Monitor and the hospital’s electronic anesthesia record (EAR) system. A backup mechanical ventilator is included for use during power failure or electronic control malfunction. The anesthesia gas scavenging system is connected to the hospital’s active vacuum system with a 50 L/min extraction capacity.

The Anesthesia Machine’s ventilator is configured for volumecontrolled, pressurecontrolled, and pressuresupport modes. For lowflow anesthesia (fresh gas flow 0.5–1 L/min), the system’s agent consumption tracking display shows realtime sevoflurane usage in mL/h. An integrated capnograph provides waveform and numeric values (EtCO₂, inspired CO₂) with a sampling rate of 200 mL/min. The machine’s backup battery provides 90 minutes of full operation during transport from OR to PACU.

Integration with the Patient Monitor is achieved via a dedicated cable transmitting heart rate, blood pressure, SpO₂, and endtidal agent concentration every five seconds. The EAR system automatically populates the anesthetic record with airway pressures, tidal volumes, and vaporizer settings at oneminute intervals. For malignant hyperthermia susceptibility, the anesthesia machine is configured to immediately stop delivering volatile agents and flush the circuit with 100% oxygen when the MH alert button is pressed.

Technical Note: The dualvaporizer configuration occupies the left and right mounting positions; a third vaporizer can be added using an auxiliary mounting bracket but reduces workspace on the machine’s top surface. The capnograph’s water trap should be emptied every two hours during long procedures; a clogged trap will falsely elevate EtCO₂ readings.

Priorto installs the Operating Microscope and the Surgical Power Tool system as an integrated visualizationinstrumentation cluster. The Operating Microscope features a 3D 4K camera head, motorized zoom (0.5–6.0x), and a 300 W xenon illumination source. The Surgical Power Tool system comprises a console, a highspeed drill (up to 80,000 rpm), a sagittal saw, and a reciprocating saw. Both systems are integrated with the OR integration system, allowing microscope video to be displayed on the auxiliary monitors while power tool parameters are recorded.

The Operating Microscope’s floor stand is equipped with five locking casters and a 1,500 mm vertical travel range. For neurosurgery, the microscope is configured with a nearinfrared (NIR) fluorescence module for visualizing indocyanine green (ICG) angiography. The microscope’s autofocus system is calibrated weekly using a USAF 1951 resolution target, maintaining focus accuracy within 0.1 mm at maximum magnification. A beam splitter is installed to allow a second observer (e.g., resident) to view the same field through an auxiliary eyepiece.

The Surgical Power Tool console is configured with presets for six common procedures: craniotomy (highspeed drill 60,000 rpm, irrigation on), total knee arthroplasty (sagittal saw 15,000 cpm), and spinal laminectomy (drill 30,000 rpm with diamond burr). Each handpiece contains a RFID chip that automatically loads the corresponding preset when attached. The console’s irrigation pump delivers 50 mL/min of saline to the cutting site, reducing thermal bone necrosis. The system’s foot pedal is configured with four modes: forward, reverse, oscillation, and irrigation.

Technical Note: The Operating Microscope’s xenon lamp should be replaced every 500 hours; the system logs lamp hours and displays a warning at 450 hours. The Surgical Power Tool’s highspeed drill burrs are singleuse; a usage counter in the console prevents reuse by locking out the handpiece after the programmed number of cycles.

Priorto configures the Electro Surgical Unit (ESU), the Ultrasonic Scalpel, and optional Argon Plasma Coagulation (APC) and LEEP modules as a comprehensive energy platform. The ESU provides monopolar cut/coag, bipolar, and advanced vesselsealing modes. The Ultrasonic Scalpel delivers 55 kHz mechanical vibration for simultaneous cutting and coagulation with lateral thermal spread below 2 mm. The APC module is installed for noncontact surface hemostasis, and the LEEP module is added for gynecologic procedures.

The ESU is configured with four monopolar outputs (cut, blend, coag, spray) and two bipolar outputs (precision and macro). The vesselsealing mode is calibrated for arteries up to 7 mm in diameter, with a tissuefeedback algorithm that stops energy delivery when the seal cycle is complete. The ESU’s patient return electrode monitoring system checks contact quality every 100 ms, interrupting power if impedance exceeds 135 Ω. The system includes a smoke evacuator that activates automatically when the ESU footswitch is pressed.

The Ultrasonic Scalpel’s handpiece is activated via a twobutton control: a yellow button for minimal coagulation (fast cut) and a blue button for maximum coagulation (slow cut). The system’s generator is configured with a default power level of 3 for general surgery, adjustable from 1 to 5. For thyroidectomy, the power is set to level 2 to reduce thermal spread to the recurrent laryngeal nerve. The scalpel’s blade is available in 14 cm, 23 cm, and 36 cm lengths, with a 5 mm diameter.

The APC module uses a 1.5 mm flexible probe and argon gas flow of 0.5–4 L/min, with power settings from 10 to 80 W. For LEEP, a dedicated generator is integrated into the ESU, delivering a pure cut waveform (90% duty cycle) for cervical loop excision. The LEEP electrode loop is available in 10 mm, 15 mm, and 20 mm widths.

Technical Note: The ESU’s vesselsealing mode requires a dedicated bipolar instrument with a blade length of at least 20 mm; using standard bipolar forceps will not achieve reliable sealing. The APC module should be used with the patient’s bowel decompressed to avoid gas distension; a rectal decompression tube is recommended for lower GI procedures.

Priorto deploys the Surgical Instrument tracking system and the Automatic Tourniquet System to ensure procedural efficiency and safety. The instrument tracking system uses RFID tags on each tray, with a reader at the OR entrance that logs which trays are brought into the room. The Automatic Tourniquet System features dualcuff capability, automatic pressure calculation based on limb occlusion pressure (LOP), and a 120minute timer with an audible alarm every 15 minutes.

The instrument tracking system’s RFID antennas are installed in the sterile core and at each OR doorway. The system is configured to generate a “missing instrument” alert if a tray’s RFID is not detected within 30 minutes of case start. For highvalue instruments (e.g., laparoscopic cameras, robotic arms), a realtime location system (RTLS) provides 1 m accuracy. The system interfaces with the hospital’s central sterile supply department (CSSD) to automate replenishment.

The Automatic Tourniquet System’s LOP measurement is performed at the beginning of each case: the cuff is inflated to 50 mmHg, then slowly increased while a Doppler probe detects the point of arterial occlusion. The system then sets working pressure at LOP + 75 mmHg for the lower limb or LOP + 50 mmHg for the upper limb. The device records cuff pressure, time inflated, and patient identification for each use, with a report generated for the surgical quality committee monthly.

Technical Note: The instrument tracking system’s RFID tags must be attached using hightemperature adhesive for instruments that undergo autoclaving at 134°C; standard tags will delaminate. The Automatic Tourniquet System’s LOP measurement should be repeated if the patient’s blood pressure changes by more than 20 mmHg during the procedure.
