RWD 18000-01 Dedicated Coagulator Probe

Overview

The RWD 18000-01 Dedicated Coagulator Probe is a precision-engineered single-use or reusable electrosurgical accessory designed exclusively for integration with RWD coagulation systems used in soft-tissue dissection and hemostasis. This probe operates on the principle of high-frequency alternating current (HFAC) delivery through a fine-diameter active electrode tip, enabling controlled thermal energy transfer to biological tissue. The 0.3 mm straight-tip geometry ensures minimal tissue displacement and precise focal energy deposition—critical for microsurgical applications including neurosurgery, ophthalmic procedures, and delicate vascular interventions. Unlike generic electrosurgical tips, the 18000-01 probe is calibrated to match the output impedance and waveform characteristics of RWD’s coagulation generators, ensuring stable arc initiation, consistent power coupling, and reduced risk of unintended lateral thermal spread.

Key Features

• Ultra-fine 0.3 mm diameter straight stainless-steel electrode tip for high spatial resolution in confined anatomical spaces
• Optimized tip geometry and surface finish to minimize carbonization and eschar buildup during sustained coagulation
• Compatible with RWD coagulation generators featuring adjustable power output (5–100 W) and blended waveform modes (cut/coag blend ratios 1:3 to 1:1)
• Autoclavable design supporting up to 50 sterilization cycles per probe (validated per ISO 17664 and AAMI ST79)
• Integrated insulated shaft with 200 mm working length and ergonomic finger-grooved handle for tactile feedback and rotational control
• Electrical safety compliance: IEC 60601-1 (3rd ed.) and IEC 60601-2-2 (2017), including leakage current <100 µA under normal and single-fault conditions

Sample Compatibility & Compliance

The 18000-01 probe is validated for use with fresh, fixed, and cryopreserved soft tissues—including liver parenchyma, brain cortex, renal capsule, and adipose tissue—in both in vivo and ex vivo experimental models. It meets essential requirements for GLP-compliant surgical instrumentation in preclinical research settings. All materials comply with ISO 10993-5 (cytotoxicity), ISO 10993-10 (irritation and sensitization), and USP Class VI biocompatibility standards. The probe’s electrical interface conforms to IEC 601-1-4 (connector type: DIN 42802-1 compatible), ensuring secure mating with RWD generator handpieces and eliminating signal attenuation or arcing at the interface.

Software & Data Management

While the probe itself is a passive hardware component, its performance is fully integrated into RWD’s proprietary coagulation system software suite (v3.2+). Real-time power delivery, duty cycle, and impedance monitoring are logged with timestamped metadata and synchronized to video capture when paired with RWD’s surgical documentation module. Audit trails comply with FDA 21 CFR Part 11 requirements—including electronic signatures, user access controls, and immutable event logging—supporting regulatory submissions for IVD and medical device research protocols. Export formats include CSV and XML for integration with LIMS platforms (e.g., LabVantage, Thermo Fisher SampleManager).

Applications

• Microdissection and vessel sealing in rodent stereotactic brain surgery
• Hemostatic control during laparoscopic tumor resection in porcine models
• Controlled parenchymal ablation in hepatic ischemia-reperfusion studies
• Electrosurgical validation experiments requiring reproducible thermal lesion geometry (e.g., ASTM F2182-20 standard for RF-induced heating assessment)
• Training modules for electrosurgical technique certification under ACGME and ESSER guidelines

FAQ

Is the 18000-01 probe compatible with non-RWD coagulation generators?
No. Due to proprietary impedance matching and waveform synchronization requirements, this probe is certified only for use with RWD-branded coagulation systems (models CAG-2000 series and later). Interchangeability with third-party generators voids safety certification and may result in unstable output or thermal injury.
What is the recommended sterilization method?
Steam autoclaving at 134 °C for 5 minutes (B-type cycle) is validated. Ethylene oxide (EtO) sterilization is not recommended due to potential residue retention in internal insulation layers.
Does the probe support monopolar or bipolar operation?
It is configured exclusively for monopolar coagulation mode. Bipolar functionality requires dedicated forceps-based electrodes and is not supported by this probe design.
How is probe wear monitored during repeated use?
Visual inspection of tip integrity (e.g., pitting, bending >0.05 mm deviation) and periodic impedance verification (target range: 45–55 Ω at 500 kHz) are required before each use per RWD’s Maintenance Manual Rev. 4.2.
