Abstract

Abstract An instrument 20 for closing trocar puncture wounds having a handle assembly 26 with a stationary portion 28 and a movable portion 30; an elongated portion 32 attached at a proximal end thereof to the stationary portion of the handle assembly; and needle deploying means 36 associated with the elongated portion. The needle deploying means includes: an actuator member 66 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 50, 52 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 108 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.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 144 words
An instrument for closing puncture wounds comprising: a) a handle assembly having a stationary portion and a movable portion; b) an elongate portion attached at a proximal end thereof to said stationary portion of said handle assembly; and c) needle deploying means associated with said elongate 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 elongate portion, said actuator member being slidable between a first position and a second position; and ii. at least one needle carrier assembly mounted adjacent said distal end of said actuator member, said needle carrier being slidable relative to said actuator member upon movement thereof, between a retracted position substantially within said elongate portion and an extended position substantially outside said elongate portion.
Claim 2
Dependent Claim 28 words
An instrument as claimed in claim 1 and further comprising: at least two elongate grooves associated with said actuator member, said grooves being dimensioned to accommodate a suture.
Claim 3
Dependent Claim 92 words
An instrument for closing puncture wounds comprising: a) elongated housing means having a longitudinal groove adjacent a distal end thereof; b) at least one needle deployably mounted and disposed within said groove of said housing; and c) means associated with said housing means independent of said needle for operably deploying said needle between a retracted position substantially within said groove and an extended position spaced from said groove in substantially the same transverse plane therewith, said needle deploying means including at least one needle carrier member slidably disposed on said deploying means.
Claim 4
Dependent Claim 20 words
An instrument as claimed in any one of the preceding claims, wherein said needle is detachable from said needle carrier.
Claim 5
Dependent Claim 29 words
An instrument as claimed in any one of the preceding claims, wherein in said extended position said at least one needle carrier is spaced radially from the longitudinal axis.
Claim 6
Dependent Claim 59 words
An instrument as claimed in any one of the preceding claims, wherein said actuator member includes at least one camming surface formed in said distal end which is slidably engaged by said at least one-needle carrier such that upon longitudinal reciprocal movement of said actutor member said needle carrier is urged between said retracted position and said extended position.
Claim 7
Dependent Claim 36 words
An instrument as claimed in any one of the preceding claims further comprising means associated with said distal end of said elongate portion for aligning said at least one needle carrier relative to said actuator member.
Claim 8
Dependent Claim 74 words
An instrument according to claim 7 wherein said aligning means includes an elongate plug member mountable adjacent said distal end of said elongate portion, said plug member having at least one substantially transverse groove defined by at least one wall portion, said wall portion being configured and dimensioned for receiving said at least one needle carrier such that said needle carrier is slidable within said groove between said retracted position and said extended position.
Claim 9
Dependent Claim 48 words
An instrument according to claim 8 wherein said wall portion is provided with a boss portion longitudinally aligned with a predetermined direction of travel of said needle carrier for cooperating therewith such that said needle carrier is guided by said boss portion in said predetermined direction of travel.
Claim 10
Dependent Claim 34 words
An instrument according to claim 9 wherein said needle carrier is provided with a slot thereon such that said slot cooperates with said boss portion of said substantially transverse groove of said plug member.
Claim 11
Dependent Claim 23 words
An instrument as claimed in any one of the preceding claims, the or each needle carrier assembly including a pair of needle carriers
Claim 12
Dependent Claim 17 words
An instrument according to claim 11 wherein said needle carriers are diametrically opposed on said elongated portion.
Claim 13
Dependent Claim 35 words
An instrument as claimed in any one of the preceding claims wherein said actuator member has means disposed thereon for receiving and retaining a length of suture between said actuator member and said elongate portion.
Claim 14
Dependent Claim 49 words
An instrument according to claim 13 wherein said suture receiving and retaining means includes at least one elongate channel disposed along said actuator member such that a length of suture may be received and retained within said channel and carried therein, between said elongate portion and said actuator member.
Claim 15
Dependent Claim 43 words
An instrument according to claim 14 wherein said suture receiving and retaining means further includes at least one retaining member associated with said actuator member adjacent said elongate channel such that a length of suture disposed in said channel is removably held therein.
Claim 16
Dependent Claim 18 words
An instrument according to claim 14 wherein said at least one retaining member is a resilient annular member.
Claim 17
Dependent Claim 31 words
An instrument according to claim 15 or 16 wherein said actuator member includes an annular groove formed therein adjacent said proximal end such that said retaining member fits within said groove.
Claim 18
Dependent Claim 22 words
An instrument as claimed in any one of the preceding claims wherein said elongate portion is configured and dimensioned for endoscopic use.
