In modern clinics, dermatology practices and primary care settings, electrosurgical devices are essential tools. They allow clinicians to perform minor procedures, such as lesion removal, skin tag excision and coagulation, quickly, safely and with minimal downtime for patients.
Among the most well-known devices in this field are the ConMed Hyfrecator 2000 and the Bovie DERM 942. While both are respected and widely used, the OBS-50 High Frequency Electric Coagulator has emerged as a highly versatile and often superior alternative. In this blog, we’ll break down how the OBS-50 compares to these devices, its technical specifications and why it’s a smart choice for clinics looking for reliable, cost-effective electrosurgical equipment.
Introducing the OBS-50 High Frequency Electric Coagulator
The OBS-50 is designed for a wide range of medical applications. It’s widely used in plastic surgery, dermatology, ENT, ophthalmology, somatology, gynaecology, proctology and urology. It supports procedures such as electrodesiccation, fulguration, and coagulation, making it a versatile tool for clinics performing minor surgical procedures.
What sets the OBS-50 apart is its ready-to-use package options. Unlike some competitors, the OBS-50 comes with all essential accessories included depending on the package chosen:
- Bronze Package: One reusable hand pencil, power cord, and disposable tips
- Silver Package: Two reusable hand pencils for multi-operator or high-volume use
- Gold Package: Includes a footswitch, reusable bipolar forceps, and both reusable and disposable electrodes
This eliminates the need for purchasing separate accessories, reducing setup time and total cost for clinics.
OBS-50 Key Features
- Adjustable power output from 10 to 30 W in 0.1 W increments
- Multiple modes: monopolar coagulation, bipolar coagulation, desiccation, and fulgurationBuilt-in memory function to retain last-used settings
- Hand pencil power adjustment to reduce operation time
- Continuous safety monitoring and power-on self-test
- Compatible with disposable dispersive electrodes
Technical Specifications:
- Monopolar Coagulation: 30 W (load 1000 Ω)
- Bipolar Coagulation: 30 W (load 200 Ω)
- Operating Frequency: 550 kHz ±10%
- Power Supply: 110–220 V, 50 / 60 Hz
- Ambient Temperature: 10–40 °C
- Relative Humidity: ≤ 80%Atmospheric Pressure: 50–106 kPa
ConMed Hyfrecator 2000: Versatile but Sold Separately
he ConMed Hyfrecator 2000 is a widely used electrosurgical device for minor procedures in dermatology, gynaecology, urology, and vasectomy. It supports coagulation, desiccation, and fulguration for warts, spider veins, skin tags, and moles.
However, a key limitation is that the Hyfrecator 2000 is sold as a base unit, with essential accessories like the mains power cable, electrodes and optional footswitch purchased separately. While this allows customisation, it increases setup time and overall costs, especially for clinics seeking a ready-to-use solution.
Key Features:
- Memory for up to 3 power settings
- Digital one tenth incremental control in the 0-10 W range
- Digital display of power output
- Finger-tip up/down power control on the reusable hand pencil
- optional footswtich
- wide range of electrode tips and disposable sterile sheaths
- Interal self-diagnostic test with visual and auditory warnings
Bovie DERM 942: Durable but Limited
The Bovie DERM 942 is engineered for reliability and durability. Its chip-based design reduces internal heat, prolonging device life and its high-impact plastic casing simplifies cleaning.
Key Features:
- Multifunction 40 W high frequency desiccator
- Adjustable in 0.1 W increments for the first 10 W in monopolar and bipolar modes
- Ground reference unit, so no grounding pad is requiredThree-button handpiece for power adjustment and activation
- Digital error detection that disables output if a fault occurs
- Lightweight (5 lbs / 2.26 kg) and compact
Electrical Specifications:
- Fulguration: 40 W
- Bipolar: 40 W
- Spray Coagulation: 40 W at 343 kHz ±10%
- Blend Coagulation: 50 W at 340 kHz ±20%
- Output Frequency: 328–492 kHz
- Line Voltage: 100–240 VAC
- Passive cooling system
Why the OBS-50 is Often the Better Choice:
The OBS-50 is often the better choice for clinics because it comes as a complete package, including all essential accessories, so there’s no need to purchase separate power cords, electrodes or handpieces. Its versatility allows it to support both monopolar and bipolar modes, as well as multiple procedural options, making it suitable for a wide range of clinical applications. Precision is a key advantage, with adjustable 0.1 W increments up to 30 W, which is ideal for delicate procedures in dermatology and primary care. The device is also easy to use, with hand pencil power adjustment, a memory function, and continuous safety monitoring that streamline workflow.
In addition, the OBS-50 offers comparable or superior functionality to the ConMed Hyfrecator 2000 and Bovie DERM 942 at a lower overall cost. It is flexible with Bronze, Silver and Gold package options to suit different clinic needs and it is trusted across multiple specialties, including dermatology, ENT, ophthalmology, plastic surgery, gynaecology, proctology and somatology.
Final Thoughts:
For clinics, dermatology practices and primary care providers looking for a reliable, versatile, and cost-effective electrosurgical device, the OBS-50 is an excellent choice. Unlike the ConMed Hyfrecator 2000, which requires additional purchases for full functionality, and the Bovie DERM 942, which can be less adaptable, the OBS-50 provides a complete, ready-to-use system with multiple package options and advanced safety features.
Whether performing minor procedures, managing multiple operators or needing both monopolar and bipolar functionality, the OBS-50 offers the precision, reliability and convenience modern clinics need.
