Claims6
A method for cauterizing tissue adjacent a surgical incision, which comprises:
- establishing and maintaining an electrically neutral, D.C. -induced cold plasma of sufficiently small cross section to permit a narrow region of contact between the plasma and tissue;
- and
- applying the plasma to tissue adjacent a surgical incision to cauterize the same.
In the method of performing surgery by contacting tissue with a plasma to form an incision, the improvement which comprises using an electrically neutral, D.C. -induced cold plasma to cauterize tissue in the region of the incision.
