Suture manipulating instrument with grasping members
First Claim
1. A surgical instrument for manipulating a surgical filament within a patient, comprising:
- an outer hollow member having a proximal end, a distal end, and a passageway extending between said proximal and distal ends;
a handle disposed on said outer member near said proximal end for enabling manipulation of said outer member;
an inner movable assembly for reciprocating through said passageway and having a proximal end and a distal end, said proximal end defining a first surface to which a first force is applied to drive said distal end of said inner assembly distally through said passageway from a retracted position to an extended position protruding distally beyond said distal end of said outer member;
said inner assembly further defining a second surface to which a second force is applied to drive said inner assembly from said extended position to said retracted position; and
said distal end of said inner assembly terminating in at least first and second grasping members for traveling past and on either side of a portion of the filament in said extended position and for encircling the filament portion in said retracted position to enable manipulation of the filament within the patent, wherein at least one of said grasping members terminates distally in a curved, hook-like element.

Abstract
A surgical instrument an outer hollow member having a passageway extending therethrough. A handle is disposed near its proximal end to enable manipulation of the outer member. An inner movable assembly reciprocates through the passageway. A distal end of the inner assembly is drivable distally through the passageway from a retracted position to an extended position protruding distally beyond the distal end of the outer member. The distal end of the inner assembly terminates in at least first and second grasper members for traveling past and on either side of a portion of a surgical filament in the extended position and for encircling the filament portion in the retracted position to manipulate the filament within the patient.

14. A surgical instrument for manipulating a surgical filament within a patient, comprising:
-
an outer hollow member having a proximal end, a distal end, and a passageway extending between said proximal and distal ends, said distal end terminating in a sharp distal tip for penetrating tissue; a handle disposed on said outer member near said proximal end for enabling manipulation of said outer member; an inner movable assembly for reciprocating through said passageway and having a proximal end and a distal end, said proximal end defining a first surface to which a first force is applied to drive said distal end of said inner assembly distally through said passageway from a retracted position fully within said passageway to an extended position protruding distally beyond said distal end of said outer member; said inner assembly further defining a second surface to which a second force is applied to drive said inner assembly from said extended position to said retracted position; and said distal end of said inner assembly terminating in at least first and second grasping members for traveling past and on either side of a portion of the filament in said extended position and for encircling the filament portion in said retracted position to enable manipulation of the filament within the patient, each of said first and second grasping members being formed of a resilient wire. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
