As energy from the energy source is applied to the needle holder through a conductive line, it is conveyed to the surgical needle through the needle holder and the energy emanating from the needle cauterizes tissue and controls bleeding as the wound is sutured closed. Bleeding from the needle tract created by the puncture of the tissue by the sharp point of the needle and passage of the needle body into the tissue that would otherwise occur as a necessary part of suture is in particular inhibited.
