Electrosurgical units are also known as Bovie units. Surgeons use these devices in surgical procedures to cut and coagulate tissue using heat. High-frequency electrical current generates heat. Electrosurgical units (ESUs) can be monopolar or bipolar:
- Bipolar units have both the active and return electrode on one instrument, with the tissue between them.
- Monopolar units pass the current from the active electrode through the patient’s body to the return electrode.
Electrosurgical units can cut tissue, vaporizing the cells using a continuous electrical waveform. They can also use an intermittent high-frequency to coagulate proteins and stop bleeding.
Making a List of Priorities for Choosing an Electrosurgical Unit in 2026
A clinic has many factors to consider when choosing an electrosurgical unit. Some of the pain points for your practice to consider include:
- Budget: Finding affordable electrosurgical machines is often a primary consideration for organizations that are choosing an electrosurgical unit.
- Space: Electrosurgery units can come in a variety of sizes. The amount of space that you have to store and accommodate the machine can influence your options.
- Safety: Electrosurgical units can cause burns, electrical shock, and potentially fire. It is important to ensure that the unit is safe for your space and electrical systems.
- Staff experience: Your staff’s comfort level factors into the decision about which unit to choose.
This guide provides reliable information, suggestions, and comparisons of the best electrosurgical units for your practice in 2026.
Why Electrosurgical Units Are Essential in Small Practices
Electrosurgical units are used for a number of surgical procedures. These units are frequently used in dermatological procedures, ENT procedures, gynecological procedures, and other minor surgeries such as toenail removals:
- Dermatologists often use electrosurgical units for procedures. They use these units to remove vascular lesions like pyogenic granulomas. They also remove benign lesions such as skin tags and moles.
Your provider may also use an ESU to treat spider veins or angiomas. It can destroy small lesions and remove skin cancers.
- Gynecologists can use electrosurgical units in the operating room. They can also treat precancerous changes in the cervix. Doctors often use Loop Electrical Excision Procedures (LEEP) to remove cervical dysplasia after abnormal pap smears.
- In otolaryngology (ENT) procedures, electrosurgical units can control bleeding and remove skin lesions.
- Many other specialties may use electrosurgical units in their offices. In the urgent care setting, electrocautery may be used to stop bleeding. Family medicine practices often perform a number of minor surgical procedures. Podiatry practices may use electrosurgical units during toenail removals or other procedures.
Electrosurgical units can improve workflow efficiency by shortening operating times and reducing blood loss. They accomplish this feat by enabling precise cutting while simultaneously coagulating the tissue. This reduces both the number of instruments needed and the number of steps required to achieve hemostasis. Less bleeding means better visualization of the surgical field, which can further shorten surgical time.
Reduced blood loss also improves patient safety by decreasing the need for blood transfusions. Electrosurgical units also allow for more precise control of the surgical margins. Cutting and coagulating simultaneously can reduce the risk of bacterial contamination and infection.
Better precision, lower infection risk, and less blood loss lead to smaller cuts. This results in less postoperative pain and a quicker recovery for patients. This improves clinical outcomes.
Electrosurgical units are a staple piece of equipment in hospital operating rooms. Small clinics face several challenges, especially compared to larger hospitals. Some of these include:
- Budget: Every facility has budget limits, but small clinics may have even tighter budgets for several reasons.
- Maintenance and training: Larger facilities may have on-site staff to maintain equipment and train new staff, while smaller clinics may not have this option. Even if large facilities lack maintenance and staff training, they can still save money. It is often cheaper to service many pieces of equipment than just a few in a small clinic.
- Obsolescence: Technology is rapidly advancing, and electrosurgical units are no exception. These advancements may necessitate more frequent upgrades and replacements as the standard of care evolves. This can be difficult for smaller facilities.
- Purchasing power: Smaller clinics usually buy in lower amounts. This means they have fewer supplier options and less bargaining power than larger hospitals. This can make it difficult to get competitive pricing.
Critical Features to Look for in 2026
As technology advances, you should look for several features when purchasing an electrosurgical unit in 2026.
Power Range
The types of surgical procedures your facility performs will affect what type of unit you may choose to purchase. Electrosurgical units have a range of power settings that are used for different applications. Many office-based procedures have lower power needs than procedures performed in operating rooms or surgery centers.
It is important to adjust the power settings of your unit. This helps meet the needs of each surgeon and the specific procedure.
Safety Systems
The safety of your patients and staff is likely a top concern when considering electrosurgical units. Electrosurgical units usually have many safety systems. These features are important to consider when buying a unit in 2026.
- Electrode monitoring: Active electrode monitoring systems will monitor the active electrode during surgery and deactivate the unit if the unit is compromised. This can help prevent burns to the patient.
- Return-electrode monitoring systems: These systems monitor the return electrode. They ensure good contact to protect the patient from burns at the return electrode sites. They will trigger an alarm and deactivate the unit as necessary.
- Alarms can be visual or audible. These will alert your staff to any concerns or potentially harmful conditions with the machine. The type and volume of the alarm may be a factor to consider in your practice.
No matter which safety features you choose, proper training for your staff is essential. This ensures everyone knows how to use the machine correctly.
Usability
An ideal electrosurgical unit should be intuitive and easy to use. Some usability features to consider include whether the unit has a foot pedal or a button on the tip to control the current.
For some clinics, a touchscreen may be preferable to dials. The easier a unit is to use, the easier it is to train. If the staff has to fiddle with the machine, it can decrease workflow efficiency.
Portability and Size
The size and portability of the unit play a key role in your choice of unit for your practice. If the unit needs to be moved in multiple locations, a smaller, more portable unit may be necessary. Some units can add features like argon lasers. These can reduce the space needed for equipment in your procedure suite or operating room.
The procedures your practice will perform can affect the number of tools and accessories you need. This can also impact the portability and size of your equipment.
Cost of Ownership
Cost of ownership is not limited to the purchase price. Other things to consider include:
- Maintenance costs
- Repair costs
- Cost of accessories (such as cautery tips, smoke evacuators, electrodes, generators, filters, etc.)
- Cost of training staff
- Energy consumption
- Disposal costs
Some ownership costs can be reduced with warranty replacements. However, all these costs should be considered when choosing the right electrosurgical unit for your practice.
