Abstract

The present disclosure relates to a surgical tool for cutting and hemostasis of biological tissues. The surgical tool includes a hollow blade comprising a cutting implement residing within a hollow cavity configured to provide high-pressure steam through an apical surface. The cutting implement can operate independently or in cooperation with the provided high-pressure steam. The surgical tool of the present disclosure applies a directionally-controlled, high-pressure steam flow to a tissue region of interest. A control unit provides temperature-controlled steam at a flow-rate determined in accordance with tissue type and intended procedure.

First claim

1 . An apparatus, comprising:
a handle, disposed at a proximal end of the apparatus, including a reservoir for storage of an ablative agent; a hollow tube, adjacent to the handle and arranged to be in fluid communication with the handle; and a head element, disposed at a distal end of the apparatus, adjacent to the hollow tube and arranged to be in fluid communication with the hollow tube, wherein the head element includes an operative element and an assisting element.

2 . The apparatus according to claim 1 , further comprising a plurality of wires extending from the proximal end of the apparatus to the distal end of the apparatus, mechanically connecting the handle with the head element.

3 . The apparatus according to claim 1 , wherein the operative element comprises a cutting implement and one or more ports through which the ablative agent can be released, the cutting implement and the one or more ports disposed at an apical surface of the operative element.

4 . The apparatus according to claim 1 , wherein the assisting element is a rotatable element with an apical surface and a basal surface, the basal surface positioned to be in intermittent contact with the operative element of the head element.

5 . The apparatus according to claim 4 , wherein the rotatable element includes an arrangement of one or more protrusions, depressions, or a combination thereof, disposed on the basal surface.

6 . The apparatus according to claim 1 , wherein the head element is fabricated to be of a shape that is substantially linear, substantially curved, or a combination thereof.

7 . The apparatus according to claim 3 , wherein the one or more ports disposed at the apical surface of the operative element are of a pre-determined shape, size, and arrangement.

8 . The apparatus according to claim 2 , wherein the head element deforms in response to a force applied to the plurality of wires at the proximal end of the apparatus, the deformation in the head element producing a curvature in the operative element and the assisting element.

9 . The apparatus according to claim 1 , wherein the head element is connected to a rotatable element, the rotatable element being substantially cylindrical in shape and rotatably-fixed about an axis of the apparatus extending from the proximal end to the distal end.

10 . The apparatus according to claim 1 , wherein the ablative agent includes steam.

11 . The apparatus according to claim 1 , further comprising a temperature control unit for controlling the temperature of the ablative agent, the temperature control unit comprising a heating element and a thermostat.

12 . An apparatus, comprising:
a head element, including an operative element and an assisting element, wherein the operative element comprises a cutting implement and one or more ports disposed at an apical surface.

13 . The apparatus according to claim 12 , wherein the one or more ports disposed at the apical surface of the operative element are of a pre-determined shape, size, and arrangement.

14 . The apparatus according to claim 12 , wherein the head element deforms in response to an applied force, the deformation producing a curvature in the operative element and the assisting element.

15 . The apparatus according to claim 12 , wherein the assisting element is a rotatable element with an apical surface and a basal surface, the basal surface positioned to be in intermittent contact with the operative element of the head element.

16 . The apparatus according to claim 15 , wherein the rotatable element includes an arrangement of one or more protrusions or depressions disposed on the basal surface.

17 . The apparatus according to claim 12 , wherein the head element is fabricated to be of a shape that is substantially linear, substantially curved, or a combination thereof.

18 . The apparatus according to claim 12 , wherein the one or more ports of the operative element direct an ablative agent to a target.

19 . The apparatus according to claim 18 , wherein the ablative agent includes steam.

20 . A method, comprising:
incising, by a cutting implement disposed on an apical surface of an operative element, a target tissue; and ablating, by an ablative agent, the incised target tissue, wherein the ablative agent is delivered to the incised target tissue via one or more ports on the apical surface of the operative element, the ablative agent coagulating the incised target tissue, and wherein the incision and ablation are performed concurrently.
