Traditional thermal cautery utilizes heat in the form of direct current to perform coagulation. This method eliminates the possibility of alternate site burns that can occur with electrosurgery. Only the heated wire tip comes in contact with the tissue and current does not enter the patient's body. WPI's Thermal Cautery Unit provides all the cautery power necessary 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.

Maintains constant temperature

The Thermal Cautery Unit maintains the desired temperature during tissue contact and does not rapidly diminish like disposable battery powered cauteries. The autoclavable handpiece with six-foot cord accepts an assortment of reusable thermal cautery electrodes, allowing the surgeon to have the flexibility to perform a wide variety of procedures. This unit will outlast battery-powered units and save money on replacement batteries.

Reusable electrode tips

501295, 501297 and 501299 are included with the unit. The other tips are optional accessories.
