Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 109 words
A miniature articulated tip tool for micro-surgical, medical and like uses, comprising: (a) means defining an articulated tip with at least one pivotable element and a sole pivot element therefor with a range of movement of said tip between extended and retracted positions for effecting selective user controlled pivotal working movements, the said tip defining means comprising at least one fixed wall with an extension thereof formed together in one piece and serving as said pivot element; (b) means defining a user control handle-actuating system; and (c) means defining an elongated linkage between the handle-actuating system and the articulable tip pivotable member and a channel including such elongated linkage.
Claim 2
Dependent Claim 109 words
A miniature articulated tip tool for micro-surgical, medical and like uses, comprising: (a) means defining an articulated tip with at least one pivotable element and a sole pivot element therefor with a range of movement of said tip between extended and retracted positions for effecting selective user controlled pivotal working movements, the said tip defining means comprising at least one fixed wall with an extension thereof formed together in one piece and serving as said pivot element; (b) means defining a user control handle-actuating system; and (c) means defining an elongated linkage between the handle-actuating system and the articulable tip pivotable member and a channel including such elongated linkage.
Claim 3
Dependent Claim 25 words
The tool of claim 1 wherein the tip has a construction of two side walls with said pivot constituting a one piece extension of both.
Claim 4
Dependent Claim 21 words
The tool of claim 2 wherein said sidewalls are essentially parallel and the one-piece pivot has essentially an hour glass form.
Claim 5
Dependent Claim 17 words
The tool of claim 1 wherein said pivotable element has a hook opening conforming to the pivot.
Claim 6
Dependent Claim 111 words
An endoscopic surgical instrument, comprising: (a) means defining an articulated tip with at least one pivotable element and a sole pivot element therefor with a range of movement of said tip between extended and retracted positions for effecting selective user controlled pivotal working movements, the said tip defining means comprising at least one fixed wall with an extension thereof formed together in one piece serving as said pivot element, and the one-piece pivot having essentially an hour glass form; (b) means defining a user control handle-actuating system; and (c) means defining an elongated linkage between the handle-actuating system and the articulable tip pivotable member and a channel including such elongated linkage.
Claim 7
Dependent Claim 111 words
An endoscopic surgical instrument, comprising: (a) means defining an articulated tip with at least one pivotable element and a sole pivot element therefor with a range of movement of said tip between extended and retracted positions for effecting selective user controlled pivotal working movements, the said tip defining means comprising at least one fixed wall with an extension thereof formed together in one piece serving as said pivot element, and the one-piece pivot having essentially an hour glass form; (b) means defining a user control handle-actuating system; and (c) means defining an elongated linkage between the handle-actuating system and the articulable tip pivotable member and a channel including such elongated linkage.
Claim 8
Dependent Claim 104 words
A grasper for micro-surgical, medical and like uses, comprising: (a) means defining an articulated tip with at least one pivotable element and a sole pivot element therefor with a range of movement of said tip between extended and retracted positions for effecting selective user controlled pivotal working movements, the said tip defining means comprising at least one fixed wall with an extension thereof formed together in one piece serving as said pivot element; (b) means defining a user control handle-actuating system; (c) means defining an elongated linkage between the handle-actuating system and the articulable tip pivotable member and a channel including such elongated linkage.
Claim 9
Dependent Claim 104 words
A grasper for micro-surgical, medical and like uses, comprising: (a) means defining an articulated tip with at least one pivotable element and a sole pivot element therefor with a range of movement of said tip between extended and retracted positions for effecting selective user controlled pivotal working movements, the said tip defining means comprising at least one fixed wall with an extension thereof formed together in one piece serving as said pivot element; (b) means defining a user control handle-actuating system; (c) means defining an elongated linkage between the handle-actuating system and the articulable tip pivotable member and a channel including such elongated linkage.
