Abstract
Abstract A laparoscopic instrument includes an elongated member having two pairs of jaws with each pair being movable between open and closed positions. Finger grips are operably connected to each pair of jaws for actuating each pair of jaws between their open and closed positions. One of the two pairs of jaws is rotatably mounted.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
125 words
A laparoscopic instrument for use in laparoscopic surgery comprising an elongated member, said elongated member having a proximal end and a distal end, first jaw means comprising two relatively movable jaw elements disposed at said distal end, second jaw means comprising two relatively movable jaw members disposed intermediate said proximal and distal ends, said first and second jaw means being movable between open and closed positions, finger grip means on said proximal end of said elongated member, said finger grip means being operably connected to said first and second jaw means for actuating said first and second jaw means between said open and closed positions, and rotating means on said elongated member for rotating one of said jaw means relative to the other jaw means.
Claim 2
Dependent Claim
125 words
A laparoscopic instrument for use in laparoscopic surgery comprising an elongated member, said elongated member having a proximal end and a distal end, first jaw means comprising two relatively movable jaw elements disposed at said distal end, second jaw means comprising two relatively movable jaw members disposed intermediate said proximal and distal ends, said first and second jaw means being movable between open and closed positions, finger grip means on said proximal end of said elongated member, said finger grip means being operably connected to said first and second jaw means for actuating said first and second jaw means between said open and closed positions, and rotating means on said elongated member for rotating one of said jaw means relative to the other jaw means.
Claim 3
Dependent Claim
41 words
A laparoscopic instrument according to claim 1, wherein said first jaw means is designated an end jaw means and said second jaw means is designated an intermediate jaw means, said intermediate jaw means being longitudinally spaced from said end jaw means.
Claim 4
Dependent Claim
35 words
A laparoscopic instrument according to claim 2, wherein said finger grip maens comprises top finger grip elements selectively operable to independently actuate said intermediate and said end jaw means between their open and closed positions.
Claim 5
Dependent Claim
33 words
A laparoscopic instrument according to claim 2, wherein said elongated member has a recess, said intermediate jaw means being disposed in said recess when said intermediate jaw means is in its closed position.
Claim 6
Dependent Claim
31 words
A laparoscopic instrument according to claim 2, wherein one of said jaw elements of said end jaw means is mounted for pivotal movement relative to the other of said jaw elements.
Claim 7
Dependent Claim
38 words
A laparoscopic instrument according to claim 1, wherein one of said first and second jaw means comprises a rod means longitudinally slidable in said elongated member, said rotating means rotatably mounted said rod means in said elongated member.
Claim 8
Dependent Claim
51 words
A laparoscopic instrument according to claim 5, wherein said rod means has a knob means, and mounting means mounting said knob means on said rod means so as to preclude relative rotation between said knob means and said rod means, said rod means being longitudinally slidable relative to said knob means.
Claim 9
Dependent Claim
41 words
A laparoscopic instrument according to claim 2, wherein said end jaw means comprises pivot means pivotably mounting one of said jaw elements on the other jaw element such that said one jaw element is pivotable relative to the other jaw element.
Claim 10
Dependent Claim
37 words
A laparoscopic instrument according to claim 8, wherein said jaw means comprises an elongated rod, said pivot means being designated a first pivot means, and second pivot means pivotally connecting said rod to said one jaw element.
Claim 11
Dependent Claim
49 words
A laparoscopic instrument according to claim 9, wherein said rod, said first pivot means, said second pivot means, said one jaw element and said other jaw element are all rotatable together as a unit about a longitudinal axis which is coincident with the longitudinal axis of said elongated rod.
Claim 12
Dependent Claim
28 words
A laparoscopic instrument according to claim 5, wherein said elongated member comprises means for precluding longitudinal sliding movement of said other jaw element relative to said elongated member.
Claim 13
Dependent Claim
33 words
A laparoscopic instrument according to claim 5, wherein said rotating means comprises means for rotatably mounting said other jaw element about a rotational axis coincident with the longitudinal axis of said elongated rod.
Claim 14
Dependent Claim
58 words
A laparoscopic instrument according to claim 2, wherein said two jaw elements of said end jaw means each have a mating surface which mate when in said closed position, one of said jaw elements being a pivotal jaw element pivotably mounted on the other jaw element, said rotating means having means for rotatably supporting said end jaw means.
Claim 15
Dependent Claim
91 words
A laparoscopic instrument according to claim 2, wherein one of said jaw elements of said end jaw means is a pivotal jaw element pivotably mounted on said other jaw element between open and closed positions, said elongated member having a longitudinal axis, said pivotal jaw element having a jaw axis which is parallel to said longitudinal axis when said pivotal jaw element is in its closed position, said pivotal jaw element having its jaw axis disposed non-parallel to said longitudinal axis when said pivotal jaw element is in its open position.
Claim 16
Dependent Claim
36 words
A laparoscopic instrument according to claim 14, wherein said jaw axis of said pivotal jaw element extends at an acute angle relative to said longitudinal axis when said pivotal jaw element is in its open position.
