Benefits of technology

[0007]The limitations of prior art devices for the excision of adenoid tissue are overcome by the apparatus, system, and method of the present disclosure comprising [a] a temperature controller, [b] a removably attachable flexible cable in electrical communication with both the temperature controller and a handpiece, and [c] a handpiece with a surgically sharp cutting edge, comparable to existing cold scalpels, combined with a heatable blade covered by a non-stick coating to minimize intra-operative and post-operative bleeding, as well as to minimize the avulsion of th

Problems solved by technology

This critical requirement results from the fact that the intended use of an adenoidectomy curette in the confined region of the throat of the patient (the curette having

first embodiment

[0062]As seen in FIGS. 2 through 7, the present disclosure enables the conduction of heating current from leads 81a and 81b to the heatable blade 30 via first and second electrically and thermally conductive blade support shanks 50 and 52 and extending to the tip of first and second electrically and thermally conductive blade support arms 51 and 53, respectively. As seen in FIG. 4, electrically insulative spacer 56 assures electrical isolation between first and second electrically and thermally conductive blade support shanks 50 and 52. Still referring to FIG. 4, adhesive bonds between first and second electrically and thermally conductive blade support shanks 50 and 52 and interspaced electrically insulative spacer 56 is provided by first and second double-sided adhesive layers 54 and 58. The adhesive bonds results in a multi-layer cantilever beam sandwich with improved stiffness to reduce deflection in the presence of applied forces at the distal end of blade support member 32 ass...

second embodiment

[0067]In the design of the present disclosure, as seen in FIGS. 11 through 13, [a] the widths and thicknesses of thermally conductive blade support shanks, 104, and first and second electrically and thermally conductive blade support arms, 131a and 131b, [b] the width and thickness of the thermally insulative spacers 62a and 62b, [c] the metal or alloy selected for use in the construction of thermally conductive blade support shank 104 and integral thermally conductive blade support arms 131a and 131b, [d] the material selected for use in construction of the thermally insulative spacers 62a and 62b, [e] the thickness and material selected for first and second electrically and thermally insulative washers 144a and 144b, [f] the thickness and material selected for first and second electrically and thermally insulative sleeves 146a and 146b and [g] the diameter and material selected for first and second fastening screws 142a and 142b have all been selected to reduce the conduction of h...

Abstract

Disclosed is a soft tissue excision apparatus having a handle and an elongated blade support member extending from the handle. The distal end of blade support member includes a first thermally conductive blade support arm and a second thermally conductive blade support arm. An electrically heatable blade is supported at and electrically isolated from the distal ends of the two thermally conductive blade support arms. A first electrically conductive lead extends from the proximal end of the thermally conductive blade support member to a first blade heater contact pad. A second electrically conductive lead extends from the proximal end of the thermally conductive blade support member to a second blade heater contact pad. First and second electrically conductive flexible leads extend from the proximal end of the thermally conductive blade support member to a controller.

Description

FIELD[0001]The field of this disclosure is an apparatus, system and method for the incision of soft tissue in humans using a mechanically sharp blade with concurrent tissue heating to effect tissue incision with minimal bleeding. By way of example, the apparatus, system, and method of the present disclosure advantageously may be applied to surgical adenoidectomy and tonsillectomy.BACKGROUND[0002]The tonsils and adenoids are generally located in the back of the nose and throat. The tonsils and adenoids serve to collect and identify bacteria and / or viruses entering the body. Once identified, the immune system is activated to produce antibodies that target the invading bacteria and / or viruses to reduce or eliminate the bacteria and / or virus-induced infection. As bacteria and viruses are incorporated within the tonsils and adenoids, these tissues are able to deconstruct the bacteria and / or virus cells wall and release cellular contents to areas of the body that produce antibodies respon...
