Instrument for closing trocar puncture wounds
First Claim
1. An instrument for closing puncture wounds comprising:
- a) a handle assembly having a stationary portion and a movable portion;
b) an elongated portion having a longitudinal axis, said elongated portion attached at a proximal end thereof to said stationary portion of said handle assembly; and
c) surgical needle deploying means associated with said elongated portion, said needle deploying means including;
i. an actuator member having a proximal end operably connected to said movable portion of said handle assembly and a distal end disposed adjacent a distal end of said elongated portion, said actuator member being slidable between a first position and a second position;
ii. at least one needle carrier assembly mounted to said actuator member adjacent said distal end thereof, said at least one needle carrier assembly being slidable relative to said actuator member upon movement thereof, wherein said at least one needle carrier assembly is movable between a retracted position substantially within said elongated portion and an extended position disposed a predetermined distance from said longitudinal axis spaced radially from said longitudinal axis and whereby said at least one needle carrier assembly is substantially outside of said elongated portion; and
iii. a needle positioned within said needle carrier.

Abstract
An instrument for closing trocar puncture wounds having a handle assembly with a stationary portion and a movable portion; an elongated portion attached at a proximal end thereof to the stationary portion of the handle assembly; and needle deploying means associated with the elongated portion. The needle deploying means includes: an actuator member having a proximal end operably connected to the movable portion of the handle assembly and a distal end disposed adjacent a distal end of the elongated portion, the actuator member being slidable between a first position and a second position; and at least one needle carrier member mounted adjacent the distal end of the actuator member, the needle carrier being slidable relative to the actuator member upon movement thereof, between a retracted position substantially within the elongated portion and an extended position substantially without the elongated portion. The instrument of the present invention also provides a novel suture retaining feature including at least one elongated channel disposed along the actuator member such that a length of suture may be received and retained within the channel and carried therein, between the elongated portion and the actuator member.
