Claim 1
Independent Claim 76 words
In an elongated hand-held and manipulated intraoral jaw defect correcting surgical instrument, an operative end portion for insertion within an interaoral surgical incision having means thereon for engaging the posterior border of the vertical ramus of a mandible, and said instrument further including a retracting portion inwards of said end portion having opposite concaveconvex surfaces for retracting the cheek and corner of the mouth during surgery with the convex surface engaging the corner of the mouth.
Claim 2
Dependent Claim 76 words
In an elongated hand-held and manipulated intraoral jaw defect correcting surgical instrument, an operative end portion for insertion within an interaoral surgical incision having means thereon for engaging the posterior border of the vertical ramus of a mandible, and said instrument further including a retracting portion inwards of said end portion having opposite concaveconvex surfaces for retracting the cheek and corner of the mouth during surgery with the convex surface engaging the corner of the mouth.
Claim 3
Dependent Claim 35 words
A surgical instrument as claimed in claim 1 and further including a shank portion having opposite concave-convex surfaces extending inwards of said retracting portion and a hand gripping portion extending inwards of said shank portion.
Claim 4
Dependent Claim 25 words
A surgical instrument as claimed in claim 2 and said retracting portion and shank portion being longitudinally bowed, and said hand grip portion being straight.
Claim 5
Dependent Claim 36 words
A surgical instrument as claimed in claim 3 and a reversely bent finger cradling tab extending from the end of said hand grip portion from the surface thereof opposite the concave surface of said retracting portion.
Claim 6
Dependent Claim 78 words
An elongated hand-held and manipulated one-piece intraoral surgical instrument comprising, a substantially flat straight hand gripping portion with a hook at the end thereof, a curved concave-convex shank portion forwardly of said hand grip portion, a curved concave-convex retracting portion forwardly of said hand grip portion and of greater width than the width of said shank portion, a tapered end portion forwardly of said retracting portion and a hook at the end thereof facing said tapered end portion.
Claim 7
Dependent Claim 78 words
An elongated hand-held and manipulated one-piece intraoral surgical instrument comprising, a substantially flat straight hand gripping portion with a hook at the end thereof, a curved concave-convex shank portion forwardly of said hand grip portion, a curved concave-convex retracting portion forwardly of said hand grip portion and of greater width than the width of said shank portion, a tapered end portion forwardly of said retracting portion and a hook at the end thereof facing said tapered end portion.
Claim 8
Dependent Claim 15 words
A surgical instrument as claimed in claim 5 and said instrument being of stainless steel.
Claim 9
Dependent Claim 226 words
