SURGICAL CAUTERY
In surgery we require to burn tissue with heat, cautery serves this limited purpose well.
With battery power it can be used at home or in the office
- An electric cautery consists of a platinum wire loop or point which becomes red hot when a current is passed through it by an electrode.
- This heated cautery point is then applied to the tissue area to cause tissue death through coagulation.
- The current source may be a low-voltage battery or a transformer connected to the mains; the transformer is preferable, as the output is more constant than that of a battery.
- The cautery must not be used any hotter than at red heat, as too high a current will cause rapid burning out of the cautery wire.
- The cautery Point are of various sizes and shapes and are mounted on a heat-resistant handle to which are connected to wires.
- The cautery must be connected to the cautery terminals.
- After connecting the wires the transformer may then be switched on.
