Surgical clip applier

摘要

A surgical clip applier, comprising a housing, a pair of handles pivotably connected to opposite sides of the housing, and a channel assembly fixedly secured to and extending from an end of the housing and carrying a series of clips in end to end relation. The surgical clip applier further comprises a jaw assembly having a pair of opposed jaw members fixedly secured to and extending from an end of the channel assembly opposite the housing, the jaw members having a clip positioned therebetween, a clip pusher member slidably disposed in the channel assembly and being operatively connected at one end to at least one of the handles, the pusher member having a nose portion at a second end for engaging a distalmost clip in the series of clips and being operable to move the distalmost clip to a position between the jaw members; and a cam plate slidably disposed in the channel assembly and being operatively connected at one end to at least one of the handles, the cam plate being operatively connected at a second end to said jaw assembly. Movement of the handles from an open position to a closed position causes the cam plate to move towards the housing to effect closure for the jaw members to deform the clip, and causes the pusher member to move towards the housing to position the nose portion behind the distalmost clip in the series of clips. Furthermore, movement of the handles from the closed position to the open position causes the cam plate to move towards the jaw assembly to effect opening of the jaw members to release the deformed clip, and causes the pusher member to move towards jaw assembly to advance the distal most clip in the series of clips to a position between the jaw members.
