Surgical clip applier.

摘要

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. <IMAGE>
