An endoscopic tool has an elongate cylindrical cannula with an open hooked end insertable into the body of a patient with a trocar element providing a laser powered flux of energy for precise incision and optional cauterization of tissue. A conventional pointed trocar may be used with the hooked cannula to permit forcible insertion of the hooked cannula end to the selected surgical site. In the alternative, a laser energy conveying trocar may be used with the hooked cannula or homeostatic insertion into the patient's body. The active distal end portion of the trocar may be provided with a selectively shaped energy-delivering tip element. The energy-delivering tip element may be provided with a subsurface heating region in which a selected implanted material converts received laser energy into heat for application to tissue held in the hooked open end portion of the cannula. Once the selected tissue is hooked, the surgeon may forcibly apply the heated or laser-energy emitting surface of the tip element to the tissue to be vaporized and incised. A cauterizing surface may be provided on the tip element of the trocar or, in the alternative to the hooked portion of the cannula.
