A surgical clip applier includes a handle assembly, an elongated shaft, a drive shaft, a cam pin, and an end effector. The cam pin is disposed in mechanical cooperation with the drive shaft. The end effector is disposed adjacent a distal end of the elongated shaft and includes a first jaw member and a second jaw member. The end effector is disposed in operative engagement with the drive shaft such that longitudinal translation of the drive shaft relative to the housing of the handle assembly causes the first jaw member to move toward the second jaw member. The first jaw member includes a first cam slot configured to slidingly receive the cam pin. The first cam slot defines a first portion having a first slope and a second portion having second slope.

Endoscopic surgical clip applier

Polymeric ligation clips and a clip applier for applying a polymeric ligation clip to tissue are disclosed herein. More particularly, the polymeric ligation clips include separate first and second beams that can be coupled to each other and are movable from a reduced diameter open position in which minimal strain is placed on the ligation clip to a clamped position and to a clip applier for delivering such a ligation clip to a surgical site.

Multi-piece ligation clip

A specimen retrieval device includes a tubular body, an inner shaft slidably positioned within a longitudinal bore of the tubular body, and a specimen bag supported on the distal portion of the inner shaft. In embodiments, the tubular body tubular body is formed of a lubricious material. The specimen bag is formed from a pattern and welded by a radiofrequency welder. The specimen bag includes a tail section through which the inner shaft passes, and the tail section may be attached to a handle at a proximal portion of the inner shaft.

Specimen retrieval device

Specimen retrieval bags, specimen retrieval devices, specimen retrieval systems, and specimen retrieval methods that are configured to facilitate the isolated removal of a tissue specimen from an internal body cavity such as, for example, during a minimally invasive surgical procedure.

Devices, systems, and methods for specimen removal

A ligation clip cartridge includes a housing and one or more retaining members. The housing defines a plurality of clip recesses that receive ligation clips. The retaining members are positioned on the housing to engage the clips within the housing in an unbiased state to minimize damage to the clip material caused by strain on the clip.

Ligation clip cartridge

A ligation clip includes a first jaw, a second jaw, and a hinge. The first jaw has a body having an inner surface defining a first clamping surface and an outer surface. The second jaw has a body having an inner surface defining a second clamping surface and an outer surface. The hinge is integrally formed with the first and second jaws and includes an inner hinge portion and an outer hinge portion. The inner hinge portion has an inner surface that is contiguous with the first and second clamping surfaces of the first and second jaws, and an outer surface. The inner surface of the inner hinge portion is defined by a plurality of curved sections. The hinge is configured to facilitate pivotal movement of the first jaw in relation to the second jaw between an open position and a clamped position.

Ligation clip with improved hinge

A ligation clip removal device includes an elongate body, a tool assembly, and a drive member. The tool assembly is supported on a distal portion of the elongate body and includes a first jaw and a second jaw pivotably supported in relation to the first jaw between an open position and a clamped position. Each of the first and second jaws includes a clip engagement surface that defines a recess having a longitudinal portion and a first transverse portion that intersects the longitudinal portion. The longitudinal portions of the recesses are configured to receive a leg of a ligation clip and the first transverse portion of the recess is configured to receive a portion of a boss of the ligation clip. The drive member is engaged with and movable in relation to the tool assembly to move the first and second jaws between the open and clamped positions.

Ligation clip removal device

A clip applier includes an outer tube, an actuation member, and an end effector. The actuation member has a distal portion including a cam member. The end effector includes a first jaw and a second jaw. Each of the first and second jaws includes a proximal portion that defines a cam slot. The cam member of the actuation member is operatively engaged with the cam slots of the first and second jaws such that movement of the actuation member from the first position to the second position causes movement of the end effector from an intermediate position to the open position and subsequently to the clamped position.

Surgical clip applier and ligation clips

A surgical ligation clip includes a first jaw and a second jaw pivotably coupled to the first jaw. The first and second jaws define first and second clamping surfaces, respectively, and have longitudinal ribs and transverse ribs that define first and second recesses on the first and second clamping surfaces. The second jaw is pivotable in relation to the first jaw from an open position to a clamped position to clamp tissue between the first and second clamping surfaces. In the clamped position, each of the longitudinal ribs on the first jaw is axially aligned with one of the longitudinal ribs on the second jaw and each of the transverse ribs on the first jaw is axially offset from each of the transverse ribs on the second jaw.

Ligation clip with retention features

A surgical ligation clip includes a first jaw, a second jaw, and a hinge portion that pivotably couples the first jaw to the second jaw. The first and second jaws define respective clamping surfaces and include locking elements. The clamping surfaces support retention structure that minimizes movement of the clamp about tissue when the ligation clip is in the clamped position. The locking elements are supported on the first and second jaws and are movable into engagement with each other to retain the ligation clip in the clamped position.

Ligation clip with latching and retention features

A surgical ligation clip includes a first jaw, a second jaw, and a hinge portion that pivotably couples the first jaw to the second jaw. The first and second jaws define respective clamping surfaces and include spaced bosses. Each of the spaced bosses include a transverse portion and a head portion that is oversized and has a diameter that is larger than the diameter of the transverse portions. The oversized head portions allow for the ligation clips to be securely supported on a clip applicator.
