Electrosurgicalbipolars.
Two-electrode instruments that cut, coagulate and seal with the current focused between the tips.
Two electrode tips.
Current flows only between the tips, so it affects just the tissue between them.
No grounding pad.
The circuit closes at the instrument, removing a monopolar source of patient burns.
Cut, coagulate, seal.
Hand switch or foot pedal selects the mode; precise work with minimal bleeding.
What it enhances.
Electrosurgical bipolars are specialized instruments used in electrosurgery to cut, coagulate or cauterize tissue while protecting the surrounding anatomy. Unlike monopolar instruments, which use a single electrode and a grounding pad, bipolar instruments carry two electrodes at the tips, which makes them particularly effective for delicate or precise procedures. By minimizing blood loss and collateral damage they support faster healing, fewer complications and shorter hospital stays.
Two electrode tips, one focused current
Bipolar instruments have two active electrodes at the tips of the instrument, placed close together so that the current flows between them through the tissue.
The current passes directly between the two electrodes, so tissue is coagulated or cut only in the area between the tips. Because it is so highly focused, the risk of injury to surrounding tissue is reduced.
No grounding pad required
Since the current flows directly between the two electrodes, bipolar instruments do not need the grounding pad that monopolar devices require. This reduces the risk of burns or injury to the patient and is one of the key benefits of bipolar electrosurgery.
Coagulation and cutting
Bipolars are used both to coagulate (stop bleeding) and to cut (remove or divide tissue). The surgeon selects the mode through a hand switch or foot pedal.
- Coagulation mode: the heat generated between the electrodes causes tissue proteins to coagulate, sealing blood vessels and controlling hemorrhage.
- Cutting mode: a more continuous current vaporizes tissue along the line of the tips for precise incisions with minimal thermal damage.
- Tissue sealing: especially effective in delicate surgery around blood vessels, where hemostasis must be achieved without unnecessary tissue damage.
A variety of tips and shapes
Tips come in a range of shapes and sizes to suit different specialties: forceps-like tips for grasping tissue, needle-like tips for precise cutting, and loop tips for coagulating larger vessels.
- Bipolar forceps: the most common type, resembling tweezers, used in delicate surgery to coagulate or divide tissue while minimizing bleeding.
- Bipolar scissors: standard scissors with electrodes at the blade tips, cutting and coagulating at the same time.
- Bipolar needle electrodes: precise coagulation or cutting in targeted areas, often in dermatology or eye surgery.
- Bipolar clamps: clamp down on vessels or tissue and apply current to coagulate or cauterize.
