Abstract
Abstract A surgical clip applier (10) comprising a housing (12, 14), a pair of handles (22) pivotally connected to opposite sides of the housing, and a jaw blade assembly (17) fixedly connected to the housing. The jaw blade assembly includes a pair of jaws (34) for receiving and deforming a clip (42) therebetween and a clip carrier (40) for supplying a series of clips to the jaws. A channel assembly (16) is slidably mounted with respect to the housing and envelops the jaw blade assembly for camming the jaws closed upon closing of the handles. The clips may be fed to the jaws by a spring biased feed bar (18) which operates upon closing of the handles, or may be urged by pusher bar (90) which provides a biasing force to the clips to be retained by the jaws. The instrument may be used in conventional surgical procedures, or may be adapted for endoscopic and laparoscopic surgical procedures requiring the application of microsurgical clips.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
177 words
An apparatus for applying vascular surgical clips in vascular surgical procedures comprising: - a handle portion: - an elongate body portion extending from said handle portion: - a pair of jaw members extending from said body portion at an end opposite said handle portion and movable between an open position for receiving a clip and a closed position for forming a clip in response to movement of said handle portion, said open position defining a a gap between said jaw members; - a plurality of clips disposed within said body portion; - advancing means for advancing said plurality of clips to urge a clip into said jaw members; and - a camming mechanism associated with said body portion for camming said jaw members from said open position to said closed position; - wherein said pusher bar member urges said plurality of clips such that each clip in said plurality is contacted by at least one other clip, said pusher bar member and said clips cooperating to urge a distalmost one of said clips between said jaw members.
Claim 2
Dependent Claim
26 words
An apparatus for applying vascular surgical clips according to claim 1, further comprising retaining means disposed on said jaws for holding a clip in said jaws.
Claim 3
Dependent Claim
28 words
An apparatus for applying vascular surgical clips according to claim 2, wherein said retaining means is complementary in shape and size to said clip received in said jaws.
Claim 4
Independent Claim
31 words
An apparatus for applying vascular surgical clips according to any of the preceding claims, wherein said jaws are disposed at an angle with respect to a longitudinal axis of said portion.
Claim 5
Dependent Claim
44 words
An apparatus for applying vascular surgical clips according to claim 4, wherein said retaining means, said advancing means and said angle of said jaws cooperate to urge a clip into said jaws and to prevent said clip from being advanced distally through said jaws.
Claim 6
Independent Claim
60 words
An apparatus for applying vascular surgical clips according to any of the preceding claims, wherein said handle portion includes a housing and a pair of handles pivotally connected to said housing and actuable in a tweezer like manner, each of said handles having a proximal and a distal end and being pivotally mounted to said housing at said proximal ends.
Claim 7
Independent Claim
67 words
An apparatus for applying vascular surgical clips according to any of the preceding claims, further comprising first spring means connected between said handles for biasing said camming mechanism in a proximal direction; and second spring means biasing said advancing means in a distal direction to push a foremost clip from said clip holding means to a position between said jaws in response to opening of said handles.
Claim 8
Independent Claim
36 words
An apparatus for applying vascular surgical clips according to any of the preceding claims, further comprising rotation control means for effectuating rotation of said elongate body portion and said jaws with respect to said handle portion.
Claim 9
Independent Claim
35 words
An apparatus for applying vascular surgical clips according to any of the preceding claims, wherein said jaws are integral with an elongate jaw assembly and said camming mechanism includes a channel enveloping the jaw assembly.
Claim 10
Dependent Claim
44 words
An apparatus for applying vascular surgical clips according to claim 9, wherein the jaw assembly includes a keyway slot which matingly engages a keyway post in said rotation control means, said keyway slot locking said jaw assembly against longitudinal movement but permitting rotation movement.
Claim 11
Dependent Claim
29 words
An apparatus for applying vascular surgical clips according to claim 10, wherein said channel assembly includes an elongate slot which slides over said keyway post to permit longitudinal movement.
Claim 12
Independent Claim
29 words
An apparatus for applying vascular surgical clips according to any of the preceding claims, wherein said elongated body portion is configured and dimensioned for insertion through a trocar cannula.
Claim 13
Dependent Claim
30 words
An apparatus for applying vascular surgical clips according to claim 12, wherein said elongate portion is a tubular portion substantially enclosing said clips, said advancing means and said camming mechanism.
Claim 14
Independent Claim
32 words
An apparatus for applying vascular surgical clips according to any one of the preceding claims, further comprising a seal to prevent passage of gas through the apparatus during an endoscopic surgical procedure.
