Abstract
Abstract An endoscopic apparatus 10 for suturing vascular tissue including a body portion 22 having a first and a second jaw 16, 18 mounted for movement on a distal end thereon and moveable between an open position spaced apart to a closed position wherein the first and second jaws are in close cooperative alignment and a handle member 20 for moving the first and second jaws to move them between the open and closed positions. The apparatus further includes a reciprocating mechanism 76 associated with the first and second jaws and movable between a first position securing a surgical needle within the first jaw and a second position releasing the surgical needle from the first jaw and a cam actuating lever 66 engagable with the reciprocating mechanism such that the cam actuating lever cams the reciprocating mechanism between the first and second positions in response to predetermined movement of the handle member.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
162 words
An endoscopic apparatus for suturing tissue comprising: a) an elongated tubular housing; b) a first and a second jaw mounted for movement adjacent a distal end of the tubular housing and remotely actuable for movement between an open position and a closed position wherein the first and second jaws are in close cooperative alignment; d) a handle member operatively associated with the proximal end of the tubular housing and actuable to move the first and second jaws between the open and closed positions; e) a reciprocating mechanism remote from the first and second jaws and movable between a first position securing a surgical needle within one of the first and second jaws and a second position releasing the surgical needle from the same one of the first and second jaw; and d) a cam actuating lever engagable with the reciprocating mechanism to cam the reciprocating mechanism between the first and second positions in response to a predetermined movement of the handle member.
Claim 2
Dependent Claim
22 words
The apparatus according to claim 1, wherein the cam actuating lever automatically cams the reciprocating mechanism subsequent to closure of the jaws.
Claim 3
Dependent Claim
65 words
The apparatus according to claim 1 or 2 wherein, the first and second jaws have respective first and second needle engaging members and the reciprocating mechanism is operatively associated with the first and second needle engaging members for alternatively moving the first and second needle engaging members into and out of engagement with a surgical needle subsequent to closure of the first and second jaws.
Claim 4
Dependent Claim
77 words
The apparatus according to claim 3, wherein the reciprocating mechanism includes a toggle wheel rotatably mounted adjacent a proximal portion of the tubular housing with a proximal end of each of the first and second needle engaging members being connected to opposite sides of the toggle wheel such that rotation of the toggle wheel simultaneously retracts one of the first and second needle engaging members and advances the other of the first and second needle engaging members.
Claim 5
Dependent Claim
57 words
The apparatus according to claim 4, wherein the cam actuating lever is mounted on the handle member, such that movement of the handle member drives the cam actuating lever into engagement with camming surfaces on the toggle wheel to rotate the toggle wheel upon movement of the first and second jaw handle member into the closed position.
Claim 6
Independent Claim
44 words
The apparatus according to any one of the preceding claims, further comprising a lockout member engagable with the reciprocating mechanism and mounted for movement between a locked position blocking movement of the reciprocating mechanism and an unlocked position allowing movement of the reciprocating mechanism.
Claim 7
Dependent Claim
36 words
The apparatus according to claim 6, wherein the cam actuating lever includes a release leg, the release leg moving the lockout member from the locked position to the unlocked position upon closure of the handle member.
Claim 8
Independent Claim
66 words
The apparatus according to any one of the preceding claims, further comprising a handle portion positioned adjacent a proximal end of the tubular housing, the handle portion including a plate mounted within the handle portion, the plate including camming structure for moving the jaws from the open position to the closed position and subsequently moving the cam actuating lever into camming engagement with the reciprocating mechanism.
Claim 9
Dependent Claim
38 words
The apparatus of claim 8, wherein said camming structure includes a cam slot and the handle member includes a cam pin mounted for movement in the cam slot for sequencing movement of the jaws and the reciprocating mechanism.
Claim 10
Dependent Claim
54 words
The apparatus according to claim 3, or any one of claims 4 to 9 as dependent on claim 3, wherein the first jaw has a first recess for receipt of a portion of a surgical needle therein, the first needle engaging member movable adjacent the first recess to engage the surgical needle disposed therein.
Claim 11
Dependent Claim
25 words
The apparatus according to claim 10, wherein the second jaw has a second recess configured to receive a portion of the surgical needle disposed therein.
Claim 12
Dependent Claim
86 words
The apparatus according to claim 11, wherein the reciprocating mechanism includes a toggle wheel rotatably affixed to the tubular housing and having first and second camming surfaces such that an initial closure of the handles forces the cam actuating lever into engagement with the first camming surface to automatically move the toggle wheel to the first position and a subsequent closure of the handles forces the cam actuating lever into engagement with the second camming surface to automatically move the toggle wheel to the second position.
Claim 13
Dependent Claim
23 words
The apparatus according to claim 12, wherein the needle engaging member is retracted proximally to secure the surgical needle in the respective arm.
Claim 14
Independent Claim
87 words
An apparatus for suturing tissue endoscopically comprising: a) an elongated body portion defining a longitudinal axis; b) a first needle holding jaw mounted for movement parallel to the longitudinal axis; c) a second needle holding jaw mounted for movement parallel to the longitudinal axis, wherein a surgical needle is held substantially perpendicular to the longitudinal axis; the needle being transferable between the first and second needle holding jaws; and d) a securing mechanism for holding the needle in one of the first and second needle holding jaws.
Claim 15
Dependent Claim
41 words
The apparatus according to claim 13, further comprising a control member for sliding the securing mechanism between a first position to secure the surgical needle within the respective jaw and a second position to release the surgical needle from the jaw.
