Tradional 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, ophthalmological, occupational 
health, ENT, and plastic surgery cases, or any 
procedure that requires accurate hemostasis.
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 electrodes have solid 1-inch brass 
shanks; tips are made with 24 gauge platinum 
wire.
These general purpose electrodes are supplied 
non-sterile, but may be autoclaved.
