Abstract

An instrument for cauterizing tissue is provided. The instrument includes a housing having an angled member with a free end. A looped cauterizing element is connected to the free end. Power is applied to the cauterizing element using a switching subassembly and a battery power source. The switching subassembly is activatable at a number of portions using a resilient boot to which the surgeon applies pressure to energize the cauterizing element. A copper conductive casing surrounds the battery power source. When the cauterizing instrument is utilized, the angled member enables the instrument to be positioned in a desirable location relative to other instruments used while cauterizing tissue.
