Abstract: A specimen retrieval device is having a housing, an outer shaft, and an inner shaft releasably supporting a pouch. The device may further include a stripper plate operably coupled to the inner shaft for movement between a retracted configuration, in which the pouch and the stripper plate are within the outer shaft, and a deployed configuration, in which the pouch and the stripper plate are outside of the outer shaft. The stripper plate may define major and minor axes, wherein the dimension along the major axis is greater than the inner diameter of the outer shaft, and the dimension along the minor axis is smaller than the inner diameter of the outer shaft. The stripper plate may include one or more apertures, e.g., to receive a support mechanism of the device, or a suture. The device may also include structure preventing premature deployment of the pouch and the stripper plate.

Abstract: A reposable surgical clip applier is provided and includes a shaft assembly having an elongated shaft and a housing assembly. The housing assembly is disposed about a proximal portion of the elongated shaft and includes a housing and a hub that is operably coupled to the elongated shaft. The housing defines a counterbore. The hub is slidably disposed within the counterbore and defines a throughhole configured to receive the elongated shaft therein. A force applied to the elongated shaft in a distal direction causes the hub to distally advance within the housing. A shaft assembly for use with a reposable surgical clip applier is also provided.

Abstract: An endoscopic surgical clip applier includes an endoscopic assembly and a handle assembly. The handle assembly includes a housing, a trigger, a drive bar, and a ratchet assembly. The ratchet assembly includes a first rack, a second rack, a pawl housing engageable with the first rack, and a second pawl engageable with the second rack. In a first position, the pawl housing is in registration with the first rack to prohibit reversal of a direction of movement of the trigger until the pawl housing is disposed beyond a proximal end or a distal end of the first rack. In a second position, the pawl housing is out of registration with the first rack to permit reversal of the movement of the trigger after the second pawl is disposed distally beyond a distal end of the second rack or proximally beyond a proximal end of the second rack.

Abstract: An endoscopic surgical clip applier includes a handle assembly having a trigger, an endoscopic assembly, a pair of jaw members, a drive bar disposed within the housing of the handle assembly, and a ratchet assembly disposed within the housing of the handle assembly. The drive bar is operatively coupled to the trigger and the pair of jaw members. The ratchet assembly includes a rack disposed on the drive bar, the rack defining a plurality of rack teeth, and a pawl housing slidably mounted within the housing of the handle assembly, the pawl housing having a pawl being selectively engageable with the plurality of rack teeth of the rack, wherein in a first position of the pawl housing, reversal of a direction of movement of the trigger is prohibited, and wherein in a second position of the pawl housing, reversal of the direction of movement of the trigger is permitted.

Abstract: A surgical clip applier is provided and includes a ratchet mechanism having a rack member connected to a drive channel such that axial translation of the drive channel results in axial translation of the rack member, the rack member defining a first set of teeth along a first side thereof and a second set of teeth along a second side thereof. The ratchet mechanism including a first pawl and a second pawl each tiltably supported in the housing and disposed on respective opposed sides of the rack member; and a buckling spring interposed between the first pawl and the second pawl and constrained in a slot formed in the rack member, wherein the buckling spring is dimensioned so as to bow in one of a proximal direction and a distal direction.

Abstract: A surgical clip applier includes a jaw assembly having first and second jaws. Each jaw defines an opposed surface configured to receive a portion of a surgical clip. The jaws are moveable between a spaced-apart position and an approximated position for forming the surgical clip about tissue. Each jaw includes a relief element disposed on a surface adjacent to and substantially transverse relative to the opposed surface thereof. The relief elements are cooperable to define a relief recess upon movement of the jaws to the approximated position. The relief recess is configured to receive at least a portion of a previously formed surgical clip during formation of a subsequent surgical clip about tissue adjacent to the previously formed surgical clip.

Abstract: An endoscopic surgical clip applier is provided, wherein a distal end of the surgical clip applier is introduced to a target surgical site through a cannula having a fixed diameter lumen. The surgical clip applier comprises an endoscopic portion supported by and extending from a handle assembly, and a pair of jaws supported at a distal end of an outer tube, wherein the pair of jaws are movable between a fully open condition and approximated conditions. When the pair of jaws are in the fully open condition the pair of jaws extend radially beyond an outer diameter of the outer tube to a dimension greater than the fixed diameter of the lumen of the cannula; and when the pair of jaws are in at least one approximated condition the pair of jaws have a transverse dimension permitting passage through the lumen of the cannula.
