Abstract
Abstract A tool is set forth defined by elongate main body with a forwardly positioned leg defined by a central bore directed through the main body and forward leg, with an enlarged cylindrical knurled handle mounted rearwardly of the main body for securement thereof for positioning interiorly of an individual's mouth cavity. The tool is geometrically configured to enchance comfort and use in its application within the cavity. A modified configuration of the invention includes a fiber optic cable superimposed within an overlying chamber mounted coextensively with the main body and forward leg, wherein the main body and forward leg extend to the forward terminal end of the forward leg to enhance viewing interiorly of the mouth cavity. A further modified configuration of the instant invention includes a valve positioned to the main body and formed with a reciprocating blade to enable manual modification of vacuum directed through the tool. The invention further contemplates the use of spaced grommets mounted on the forward leg to enhance positioning of the forward leg interiorly of the mouth cavity.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
274 words
A surgical suction tool comprising, a main body defined by a first cylindrical tube member including a first bore, wherein the first bore is defined by a first axis, and a second cylindrical tube means including a second bore, wherein the second bore is defined by a second axis, the first bore and the second bore in angular aligned communication with one another, wherein the first axis is oriented at an obtuse angle relative to the second axis, and the first cylindrical tube terminating in a tapered forward end, the first tube and the second tube defined by as predetermined diameter, and a cylindrical knurled handle member integrally surroundingly mounted and coaxially aligned about a rear end portion of the second cylindrical tube, wherein the knurled handle member is defined by a handle diameter greater than said predetermined diameter, and a further tube in communication with said first bore directed through said handle, wherein the further tube extends rearwardly of said handle in communication with a vacuum source, and including an upper bore defined by an upper bore axis, the upper bore and upper bore axis are aligned parallel to the first tube and the second tube and spaced therefrom, the upper bore further including a fiber optic cable directed through the upper bore and defined by an external configuration complementary to that defined by an internal configuration of the upper bore, and wherein the fiber optic cable is coextensive with the first tube and the second tube and extends through the handle and rearwardly thereof, and including a fiber optic connection means for securement of the fiber optic cable to an illumination source.
Claim 2
Dependent Claim
274 words
A surgical suction tool comprising, a main body defined by a first cylindrical tube member including a first bore, wherein the first bore is defined by a first axis, and a second cylindrical tube means including a second bore, wherein the second bore is defined by a second axis, the first bore and the second bore in angular aligned communication with one another, wherein the first axis is oriented at an obtuse angle relative to the second axis, and the first cylindrical tube terminating in a tapered forward end, the first tube and the second tube defined by as predetermined diameter, and a cylindrical knurled handle member integrally surroundingly mounted and coaxially aligned about a rear end portion of the second cylindrical tube, wherein the knurled handle member is defined by a handle diameter greater than said predetermined diameter, and a further tube in communication with said first bore directed through said handle, wherein the further tube extends rearwardly of said handle in communication with a vacuum source, and including an upper bore defined by an upper bore axis, the upper bore and upper bore axis are aligned parallel to the first tube and the second tube and spaced therefrom, the upper bore further including a fiber optic cable directed through the upper bore and defined by an external configuration complementary to that defined by an internal configuration of the upper bore, and wherein the fiber optic cable is coextensive with the first tube and the second tube and extends through the handle and rearwardly thereof, and including a fiber optic connection means for securement of the fiber optic cable to an illumination source.
Claim 3
Dependent Claim
129 words
A surgical suction tool as set forth in claim 1 further including a valve member mounted forwardly of said handle, and the valve member includes a housing in surrounding relationship to said first tube, the housing including a blade member reciprocatably mounted within said housing selectively overlying said first bore, the blade member including a blade boss directed upwardly through said housing and secured to said blade member, and said boss further including a head member orthogonally and integrally mounted to an upper end of said boss, and a coil spring captured between said head member and said housing to normally bias said blade member upwardly in said housing to permit vacuum communication between said further tube and said first cylindrical tube member and said second cylindrical tube member.
Claim 4
Dependent Claim
44 words
A surgical suction tool as set forth in claim 2 further including a first and second soft grommet selectively securable onto said second tube member in a spaced relationship thereon to provide an abutment for positioning said second tube member within a body cavity.
Claim 5
Dependent Claim
78 words
A surgical suction tool as set forth in claim 1 wherein said predetermined diameter is equal to 0.1875 inches, and said handle diameter is equal to 0.4375 inches, and said handle is defined by a handle length equal to 0.75 inches, and said first cylindrical tube member and said second cylindrical tube member are defined by a main body length equal to 4.25 inches, and said first bore and said second bore are substantially equal to 0.125 inches.
