21. A surgical clip applier, comprising:
-
a housing; at least one handle pivotably connected to the housing; a channel assembly extending from the housing; a jaw assembly including a pair of jaws extending from an end of the channel assembly, opposite the housing, the jaw assembly movable between a spaced apart position and an approximated position in response to movement of the at least one handle; a drive channel slidably disposed within at least one of the housing or the channel assembly, the drive channel having an end operatively connected to the at least one handle; a wedge plate slidably disposed within at least one of the housing or the channel assembly, the wedge plate including a proximal end portion operably coupled to the drive channel such that the wedge plate is moved in a direction opposite to the drive channel, and a distal end portion configured for selective operative interposition between an inner surface of each of the pair of jaws of the jaw assembly, wherein when the at least one handle is moved in a first direction, the drive channel is moved in a distal direction and the wedge plate is moved in a proximal direction such that the distal end portion of the wedge plate is withdrawn from the inner surface of each of the pair of jaws to enable the pair of jaws to move to the approximated position, and wherein when the at least one handle is moved in a second direction, the drive channel is moved in the proximal direction and the wedge plate is moved in the distal direction such that the distal end portion of the wedge plate is disposed between the inner surface of each of the pair of jaws to move the pair of jaws to the spaced apart position. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A surgical clip applier, comprising:
-
a housing; at least one handle extending from the housing; a pair of jaws extending from an end of the channel assembly, opposite the housing, the pair of jaws movable between a spaced apart position and an approximated position in response to movement of the at least one handle; a channel assembly connected to and extending from the housing; a clip carrier disposed within the channel assembly and defining a channel; a plurality of clips slidably disposed within the channel of the clip carrier; a drive channel slidably disposed within at least one of the housing or the channel assembly, the drive channel including a strap at a distal end portion thereof, the strap configured and dimensioned to selectively engage the pair of jaws in order to effectuate closure of the pair of jaws in response to movement of the at least one handle; and a lockout disposed in a distal end portion of the channel assembly, wherein when a last clip of the plurality of clips is expelled from the clip applier, a lockout tab of the lockout is urged to extend across a movement path of the strap of the drive channel, wherein the lockout tab of the lockout prevents the strap of the drive channel from moving distally such that the drive channel is prevented from moving distally. - View Dependent Claims (35, 36, 37, 38, 39, 40)
