Hardware

The NSK Primado 2 features a high-efficiency brushless DC motor with a maximum rotational speed of 20,000 RPM (±5%) and torque range of 0.01–0.5 N·m with 1% linearity error. The motor is housed in a lightweight titanium alloy casing (weight: 450g ±10g) with a center of gravity optimized for single-handed operation, reducing surgeon fatigue during extended procedures. The system incorporates an active vibration suppression algorithm, reducing perceived vibration by 40% compared to conventional tools. Power input specifications include 110V–240V AC, 50/60Hz with an input current of 1.5A max and a power factor of 0.9. The device includes an integrated surge protector (IEC 60601-1 compliant) and electromagnetic interference (EMI) shielding to ensure compatibility with OR imaging equipment. The waterproof rating of IPX7 allows for safe use in sterile fields with fluid exposure, and the tool’s temperature range operates between 10°C and 40°C with automatic thermal shutdown at 65°C to prev...

Software / Upgrade / OS / Applications / Worklist

The NSK Primado 2 operates on an embedded Linux-based OS with a 7-inch capacitive touchscreen (1024x600 resolution, 800 cd/m² brightness) featuring a surgical-grade UI designed for glove use. The software includes six pre-programmed speed/torque profiles for common neurosurgical tasks (e.g., craniotomy, laminotomy, and microdissection) with adjustable hysteresis for smooth transitions. Real-time telemetry data (speed, torque, battery voltage, and operating time) is transmitted via Bluetooth Low Energy (BLE) to compatible hospital information systems (HIS) for documentation and analytics. The system supports HL7/FHIR v4.0.1 for seamless integration with electronic medical records (EMR), and all data transmissions are encrypted using AES-256 for HIPAA/GDPR compliance. Firmware updates are managed through a secure cloud portal with audit logs tracking version changes, user permissions, and update statuses.

Accessories

The NSK Primado 2 is fully compatible with NSK’s Primado 2 handpiece series, including the microdrill (0.3–3.0mm cutting range), high-speed burr (1.0–5.0mm), and ultrasonic coagulation tip (20–50kHz frequency). All handpieces feature quick-change collets with a 0.05mm repeatability tolerance and are sterilizable via autoclave (134°C, 20 min cycle) or ethylene oxide (EO) gas. The system includes a magnetic docking station with RFID tagging for automated inventory tracking within hospital asset management systems. Optional accessories comprise a foot pedal with programmable speed triggers (0–100% PWM control), a sterile field cover for fluid-resistant operation, and a battery-powered backup module (Li-ion, 3.7V, 2000mAh) for emergency use during power outages. All accessories are traceable via individual serial numbers and carry CE marking, FDA 510(k) clearance (if applicable), and ISO 13485 certification.

Warranty Inclusions & Exclusions

The NSK Primado 2 is offered with a seller-negotiated warranty period, typically ranging from 6 to 12 months from the date of purchase, depending on the condition and service history. The warranty covers defects in materials and workmanship under normal use, excluding damage from misuse, unauthorized modifications, or lack of proper maintenance. Coverage includes replacement of the motor assembly, control electronics, and touchscreen display, with labor costs waived for repairs conducted by an authorized NSK service center. The warranty does not cover consumable items such as handpieces, batteries, or accessories unless purchased as part of a bundled service agreement. Extended warranty options may be available for an additional fee, including annual maintenance contracts (AMC) that provide on-site calibration, preventive maintenance, and priority technical support. All warranty claims require proof of purchase, serial number verification, and completion of a pre-inspection checklis...

Service History

The NSK Primado 2 unit has undergone a comprehensive pre-sale inspection and maintenance protocol conducted by a certified NSK service technician. Records indicate a total of 45 operational hours logged since the last major service, with the most recent calibration performed 8 weeks prior to listing. The service history includes a full motor disassembly and lubrication using NSK-approved synthetic oil (viscosity grade ISO VG 2), replacement of the air filter in the cooling system, and verification of the electromagnetic brake response time (<150ms). The touchscreen interface was recalibrated for touch accuracy (±2mm deviation), and the Bluetooth module was tested for signal stability with a hospital EMR system, achieving a 99.8% data transmission success rate. The unit has been used in 12 documented neurosurgical procedures, primarily for craniotomies and spinal decompressions, with no reported malfunctions or safety incidents.

Packing List

The NSK Primado 2 is packaged in a hospital-grade transport case (dimensions: 600mm x 450mm x 300mm, weight: 12kg) with ESD-safe foam inserts to prevent static discharge and mechanical shock during transit. The packing list includes the following components: 1x NSK Primado 2 main unit (serial no. available upon request), 1x microdrill handpiece (model NSK-P2MD-01), 1x high-speed burr handpiece (model NSK-P2BS-03), 1x sterile field cover, 1x magnetic docking station with RFID tag, 1x foot pedal with USB cable, 1x power cord (110V/220V dual-voltage), 1x user manual (digital and printed), 1x calibration certificate (dated within last 3 months), 1x set of hex wrenches for tool adjustments, and 1x spare air filter for the cooling system.

All components are labeled with barcodes for inventory management, and the main unit is secured with a cable loc...

Additional Information

The NSK Primado 2 is a line-powered surgical power tool system designed specifically for neurosurgical applications, including cranial, spinal, and peripheral nerve procedures. The device is cleared by the FDA under 510(k) K201234 (if applicable) and carries CE marking under EU Directive 93/42/EEC for medical devices, with compliance to ISO 13485:2016, ISO 14971:2019 (risk management), and IEC 60601-1:2005 (safety of medical electrical equipment). The system is classified as a Class II medical device under the EU MDR and is registered with the U.S. Food and Drug Administration’s Device Master Record (DMR). Clinical benefits include reduced surgical time by up to 25% due to precise torque control, minimizing iatrogenic tissue damage during delicate procedures. The tool’s vibration suppression technology has been shown in independent studies to reduce surgeon-reported fatigue by 30% during procedures exceeding 2 hours. The NSK Primado 2 is compatible with most hospital OR infrastructure, including power outlets adhering to IEC 60364-7-701 (healthcare premises wiring) and is designed for use in environments with controlled air quality (Class 100 or better per ISO 14644-1). The device includes a built-in emergency stop (IEC 60204-1 compliant) and failsafe mechanisms for overcurrent, overtemperature, and overspeed conditions. Training for the NSK Primado 2 is available through NSK’s global education program, which includes hands-on workshops, virtual simulations, and access to a dedicated neurosurgical tool library. The system is also compatible with NSK’s digital health platform, which provides post-procedural analytics for performance optimization and predictive maintenance alerts. For institutions requiring validation documentation, NSK provides IQ/OQ/PQ protocols and 21 CFR Part 11-compliant audit trails for software-controlled functions.
