BovieElectrosurgery and electrocautery (also called thermal cautery) are not synonymous. In electrosurgery, electrical energy, also called current, may be converted to heat energy. The heat produced this way is used in medical procedure to cut coagulate, desiccate or remove unusual grouts. Electrocautery is a technique using high frequency to remove unwanted tissues, make incisions or coagulate. This procedure was invented by Dr. Bovie. 

  1. Disposable Cautery
    Bovie Low Temperature cauteries differ by their tips and temperatures. Fine tip 1300°F Adjustable fine tip 700-1200°F Elongated fine tip 1100°F Micro fine tip 850°F Bovie Low Temperature cauteries offer a 4-year shelf life and are some of the highest quality cauteries on the market. Bovie high temp cauterizes are popular for a number of procedures like hemostasis, controlling diffuse bleeders, and any number of other applications.

  2. Economy Electrosurgical Unit
    Electrosurgery utilizes alternating current at radio frequencies to cut and coagulate. This category includes the unit and all the electrodes and accessories that go with it. This electrosurgery system is designed for laboratory use.
  3. Electrosurgical Accessories
    The accessories in this category are commonly used items for electrosurgery and electrocautery. For example, a foot switch, flexible light source or desiccator wall mount are frequently found in a research lab doing electrosurgery or electrocautery.
  4. Thermal Cautery Units
    Traditional thermal cautery uses heat from direct current to cauterize living tissue and limit bleeding at the incision site. Thermal cautery eliminates the possibility of alternate site burns that can occur with electrosurgery. Electric current never enters the subject's body. WPI's Thermal Cautery Unit provides all the cautery power necessary for treating numerous minor surgical conditions in a research laboratory. Our thermal cautery units are ideal for dermatology experimentation, ENT and plastic surgery applications, or any procedure that requires accurate hemostasis. This micro cautery unit is designed for use in a research laboratory. Looking for a particular Bovie part number? Find the WPI part number of a Bovie instrument.


  • Electrosurgery passes current through the patient and is not suitable for some applications. Our electrosurgical unit allows for cutting, blended cutting, coagulating, fulgurating and bipolar applications.
  • On the other hand, electrocautery passes the current through a metal wire electrode, causing it to heat. This current does not pass through the living tissue. Our thermal cautery unit is suitable for treating numerous minor surgical conditions and is ideal for applications such as dermatological, ENT, and plastic surgery cases, or any procedure that requires accurate hemostasis.
