Claim 1
Independent Claim
205 words
An electrocautery device including an outer housing, a coaxial conductor, and first and second conductor pins, the coaxial conductor having an outer conductor, an inner conductor, a first terminal end, and a second terminal end, the inner conductor and the outer conductor separated for substantially their full length by an insulator, the insulator removed from the inner conductor at the first terminal end, the outer conductor electrically connected to the first conductor pin at the second terminal end, the inner conductor electrically connected to the second conductor pin at the second terminal end, the first terminal end having an electrically active tip and an electrically active portion of the first terminal end spaced from the tip, the outer conductor, the inner conductor and the first and second conductor pins, forming a sub-assembly, the outer housing formed in one unitary section over the sub-assembly having opposite ends with the first and second conductor pins and the first terminal end extending from the opposite ends of the housing, first and second bends formed in the outer conductor in opposed direction to each other, in close proximity to the second terminal end with the first bend positioned further away from the second terminal end than the second bend.
Claim 2
Dependent Claim
205 words
An electrocautery device including an outer housing, a coaxial conductor, and first and second conductor pins, the coaxial conductor having an outer conductor, an inner conductor, a first terminal end, and a second terminal end, the inner conductor and the outer conductor separated for substantially their full length by an insulator, the insulator removed from the inner conductor at the first terminal end, the outer conductor electrically connected to the first conductor pin at the second terminal end, the inner conductor electrically connected to the second conductor pin at the second terminal end, the first terminal end having an electrically active tip and an electrically active portion of the first terminal end spaced from the tip, the outer conductor, the inner conductor and the first and second conductor pins, forming a sub-assembly, the outer housing formed in one unitary section over the sub-assembly having opposite ends with the first and second conductor pins and the first terminal end extending from the opposite ends of the housing, first and second bends formed in the outer conductor in opposed direction to each other, in close proximity to the second terminal end with the first bend positioned further away from the second terminal end than the second bend.
Claim 3
Dependent Claim
243 words
An electrocautery device including an outer housing, coaxial conductor, and first and second conductor pins, the coaxial conductor having an outer conductor, an inner conductor, a first terminal end, and a second terminal end, the inner conductor and the outer conductor separated for substantially their full length by an insulator, the insulator removed from the inner conductor at the first terminal end, the second terminal end spaced from the first terminal end, the outer conductor electrically connected to the first conductor pin at the second terminal end, the inner conductor electrically connected to the second conductor pin at the second terminal end, the first terminal end having an electrically active tip and an electrically active portion of the first terminal end spaced from the tip, the outer conductor, the inner conductor and the first and second conductor pins, forming a sub-assembly, the outer housing formed in one unitary section over the sub-assembly having opposite ends with the first and second conductor pins and the first terminal end extending from the opposite ends of the housing, the coaxial conductor including an elbow portion, the elbow portion in close proximity to the first terminal end, a portion of the outer conductor of the coaxial conductor being removed from the elbow portion to just above the first terminal end exposing the inner conductor while maintaining the separation of the inner conductor and the outer conductor by the insulator to form an electrically active wide stroke portion.
