Abstract
Abstract An electrosurgical forceps comprising two blades which are electrically connected to an electrosurgical frequency generator so that electrosurgical radio frequencies can be transmitted from the generator to the blades. The blades are separated by a spacer member formed with a middle section defining inwardly inclined surfaces which hold the wires in a secured position against the forceps blades away from each other. The wire ends are bent down in channels formed in the spacer element and an elastomeric tubing is shrink fit around the ends of the blades to secure the spacer element and non-insulated wire ends in a fixed position.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
133 words
An electrosurgical forceps comprising two electrically conductive blades each blade having a forward end and a rear end, an electrosurgical frequency carrying insulated wire means for connecting only said forceps blades to an electrosurgical frequency generator, said wire means being secured to said forceps blades and adapted to be connected to said generator, a spacer means constructed of insulative material secured between the rear ends of said blades, said spacer means comprising a front section and a rear section, both sections conforming to the shape of the forceps blades and a middle section defining two inclined serrated surfaces extending between the front section and rear section, said inclined serrated surfaces engaging said wire means to secure the wire means against said forceps blades in direct electrical contact with each of the forceps blades.
Claim 2
Dependent Claim
133 words
An electrosurgical forceps comprising two electrically conductive blades each blade having a forward end and a rear end, an electrosurgical frequency carrying insulated wire means for connecting only said forceps blades to an electrosurgical frequency generator, said wire means being secured to said forceps blades and adapted to be connected to said generator, a spacer means constructed of insulative material secured between the rear ends of said blades, said spacer means comprising a front section and a rear section, both sections conforming to the shape of the forceps blades and a middle section defining two inclined serrated surfaces extending between the front section and rear section, said inclined serrated surfaces engaging said wire means to secure the wire means against said forceps blades in direct electrical contact with each of the forceps blades.
Claim 3
Dependent Claim
19 words
An electrosurgical forceps as claimed in claim 1 wherein said spacer means is constructed of a plastic insulating material.
Claim 4
Dependent Claim
28 words
An electrosurgical forceps as claimed in claim 1 wherein said spacer means defines channel means on each opposite side adjacent the nearest blade for holding said wire means.
Claim 5
Dependent Claim
42 words
An electrosurgical forceps as claimed in claim 1 wherein said wire means comprises two wires ecch having a non-insulated end secured to a blade and said spacer means separates the non-insulated ends of said wires and prevents them from contacting each other.
Claim 6
Dependent Claim
25 words
An electrosurgical forceps as claimed in claim 1 wherein the spacer means and rear ends of the forceps blades are covered by an elastomeric tubing.
Claim 7
Dependent Claim
27 words
An electrosurgical forceps as claimed in claim 5 wherein the elastomeric tubing is shrink fit around the rear ends of the forceps blades and said spacer means.
Claim 8
Dependent Claim
126 words
An electrosurgical forceps comprising two tweezer shaped electrically conductive blades, an electrosurgical frequency carrying insulated wire means having two uninsulated ends adapted to connect said tweezer blades to an electrosurgical frequency generator, a wire connecting means for connecting said ends to each of the blades of said forceps while precluding the wire ends from contacting each other, said wire connecting means comprising a molded insulative spacer element secured between the blades and defining a body having a front section, a rear section and a middle section, the middle section being formed with inclined surfaces engaging the uninsulated ends of said wire means to hold the uninsulated ends in a secured position in contact with the forceps blades when the ends are secured to the inclined surfaces.
Claim 9
Dependent Claim
126 words
An electrosurgical forceps comprising two tweezer shaped electrically conductive blades, an electrosurgical frequency carrying insulated wire means having two uninsulated ends adapted to connect said tweezer blades to an electrosurgical frequency generator, a wire connecting means for connecting said ends to each of the blades of said forceps while precluding the wire ends from contacting each other, said wire connecting means comprising a molded insulative spacer element secured between the blades and defining a body having a front section, a rear section and a middle section, the middle section being formed with inclined surfaces engaging the uninsulated ends of said wire means to hold the uninsulated ends in a secured position in contact with the forceps blades when the ends are secured to the inclined surfaces.
Claim 10
Dependent Claim
15 words
An electrosurgical forceps as claimed in claim 7 wherein said spacer element is polycarbonate plastic.
Claim 11
Dependent Claim
18 words
An electrosurgical forceps as claimed in claim 7 wherein said inclined surfaces are formed with incremental angular steps.
Claim 12
Dependent Claim
27 words
An electrosurgical forceps as claimed in claim 9 including a shrink material covering shrink fit over said spacer element and at least a portion of said blades.
Claim 13
Dependent Claim
21 words
An electrosurgical forceps as claimed in claim 7 including rivet means projecting from said spacer element body secured to said blades.
Claim 14
Dependent Claim
16 words
An electrosurgical forceps as claimed in claim 7 wherein said tweezer shaped blades are bayonette shaped.
