About Electrosurgery
Electrosurgery equipment uses high-frequency electrical current to cut tissue and control bleeding with precision. This collection includes Bovie electrosurgical generators and desiccators, disposable and reusable electrosurgical pencils, needle electrodes, monopolar and bipolar cords, footswitches, return electrodes and adapters. It also covers surgical smoke evacuation with the Smoke Shark line, battery-style Adjust-A-Temp fine tip cautery, cautery tip cleaners, pencil sheaths and the BD Venclose Maven RF ablation catheter. Products come from Aspen Surgical, including its Bovie line, Olsen and BD. Operating rooms, surgery centers, OB/GYN and dermatology offices, and outpatient procedure rooms use these products to perform cutting and coagulation and to keep the room's air clearer during procedures.
Why Electrosurgery Is Essential
Few tools have changed surgery as much as electrosurgery. A single pencil can cut through tissue and seal small vessels as it goes, which helps keep the field visible and can shorten the time spent controlling bleeding. That combination is why electrosurgical units are found in nearly every operating room and in many office-based practices.
Electrosurgery is also a system, and every part matters. A generator is only as reliable as the pencil, cord, footswitch and return electrode connected to it. A mismatched connector or worn cord can interrupt a case. Teams need compatible accessories on hand.
Surgical smoke is part of the picture too. Electrosurgery creates a plume that can affect visibility and the comfort of the people in the room. Smoke evacuators and pencil adapters capture that plume at the source. Choosing the right equipment supports both the patient on the table and the staff around it.
What Is Electrosurgery?
Electrosurgery uses a generator to deliver high-frequency alternating current through an active electrode, such as a pencil blade or needle, to tissue. The current produces heat in the tissue, which can cut, coagulate or desiccate depending on the waveform and settings.
In monopolar electrosurgery, current flows from the active electrode through the patient to a return electrode. In bipolar electrosurgery, current passes between two tips of an instrument, such as forceps, so only the tissue between them is affected.
Thermal cautery devices like the Adjust-A-Temp work differently, using a heated tip rather than current through the patient. Smoke evacuators filter the plume produced during these procedures.

Benefits of Electrosurgery Equipment
Cutting and coagulation in one tool. A single pencil can cut tissue and seal small vessels, which helps keep the field visible.
Precise control. Generator modes, needle electrodes and bipolar options let clinicians tailor the tissue effect to the task.
Flexibility across specialties. From a 300W OR generator to a 40W dermatology desiccator, there are options for hospital and office settings alike.
Cleaner air in the room. Smoke evacuators and pencil adapters capture plume at the source, which supports visibility and staff comfort.
Fewer workflow interruptions. Keeping spare cords, footswitches, return electrodes and adapters on hand means a worn accessory does not stop a case.
Choice of disposable or reusable. Facilities can choose sterile single-use pencils for convenience or reusable pencils and cords that are reprocessed per manufacturer instructions.
How to Choose the Right Electrosurgery Equipment
Start with your generator. Most accessory decisions depend on it, so note the make and model and check each listing's compatibility information. Connector styles, such as twin pin, 28 mm fixed pin or 4 mm active, must match both the instrument and the generator.
Next, think about the procedure. OR cases often call for a high-power generator and smoke evacuation. Office gynecology and LEEP work may suit a Bantam PRO package. Dermatology may need a desiccator, needle electrodes or fine tip cautery.
Choose pencil activation by surgeon preference. Some prefer hand controls such as rocker or button switches, while others prefer a footswitch. Decide between disposable and reusable based on your reprocessing capacity.
Plan for smoke. If your facility uses smoke evacuation, budget for replacement filters, hoses and pencil adapters alongside the evacuator itself.
Frequently Asked Questions
1. What is the difference between monopolar and bipolar electrosurgery?
In monopolar electrosurgery, current travels from the active electrode through the patient to a return electrode. In bipolar electrosurgery, current flows between two tips of one instrument, affecting only the tissue between them. Each requires the appropriate cords and accessories.
2. Is electrosurgery the same as electrocautery?
Not exactly. Electrosurgery passes current through tissue. Thermal cautery, like the Adjust-A-Temp devices, uses a heated tip to treat tissue directly. The terms are often used loosely, but the mechanisms differ.
3. Will these cords work with my generator?
Check the connector type and any generator models named in the product listing. For example, the Bovie reusable bipolar cord lists A800EU, A900, A940 and A950 generators. When in doubt, confirm with the generator manufacturer's documentation.
4. Why use a smoke evacuator?
Electrosurgery creates surgical smoke. A smoke evacuator captures the plume at the source, which helps keep the field visible and reduces smoke in the room. Follow your facility's policies on smoke evacuation.
5. Should I choose a hand-activated or foot-activated pencil?
It comes down to surgeon preference and the procedure. Hand-activated pencils use rocker or button switches on the pencil, while foot-activated pencils work with a footswitch. Both are available in this category.
6. Can reusable pencils be autoclaved?
Some reusable pencils, such as the Aspen Bovie 3-button model, are listed as autoclavable. Always follow the manufacturer's reprocessing instructions for each product.
