The surgical instrument includes a handle assembly, an elongated portion extending distally from the handle assembly and defining a longitudinal axis, and an end effector disposed adjacent a distal portion of the elongated portion. The end effector includes a first jaw member and a second jaw member. The first jaw member defines a first axis, which is transverse to the longitudinal axis. The first jaw member is pivotable about the first axis. At least one of the first jaw member and the second jaw member is movable with respect to the other between a spaced-apart and an approximated position. | 02-11-2016 |
20160045213 | SURGICAL CLAMP INSERT WITH DIRECTION INDICATOR - A pad configured to attach to a jaw of a surgical clamp includes an elongate body configured to extend over a surface of a jaw of a surgical clamp; and a flexible elongate attachment member connected to said body and configured for slidable insertion in a loading direction into an elongate cavity extending longitudinally through said jaw, wherein the elongate body has a first end and a second end, wherein the first end is configured to be inserted first into the cavity, and further comprising a direction indicator to identify which end is first inserted into said cavity. A surgical clamp utilizing the pad is also disclosed. | 02-18-2016 |
20160066940 | MEMBRANE REMOVING FORCEPS - A membrane removing forceps may include a first forceps jaw having a first forceps jaw distal end and a first forceps jaw proximal end and a second forceps jaw having a second forceps jaw distal end and a second forceps jaw proximal end. The membrane removing forceps may include one or more abrasive surfaces configured to raise a portion of a membrane. A surgeon may raise a portion of a membrane by grazing the portion of the membrane with one or more abrasive surfaces of a membrane removing forceps. The surgeon may grasp the raised portion of the membrane with the first forceps jaw distal end and the second forceps jaw distal end. The surgeon may then remove the membrane by peeling the membrane apart from an underlying tissue. | 03-10-2016 |
20160074219 | ATRAUMATIC MICROSURGICAL FORCEPS - An atraumatic microsurgical forceps may include an actuation structure, an actuation sleeve having an actuation sleeve distal end and an actuation sleeve proximal end, a surgical blank, and atraumatic forceps jaws of the surgical blank having atraumatic forsceps jaws distal ends and atraumatic forceps jaws proximal ends. The surgical blank may be disposed within the actuation sleeve wherein at least a portion of the atraumatic forceps jaws extends from the actuation sleeve distal end. A compression of the actuation structure may be configured to gradually extend the actuation sleeve over the atraumatic forceps jaws proximal ends. An extension of the actuation sleeve over the atraumatic forceps jaws proximal ends may be configured to gradually close the atraumatic forceps jaws wherein the atraumatic forceps jaws initially contact at the atraumatic forceps jaws distal ends. | 03-17-2016 |
20160113668 | INSTRUMENT WITH RESILIENT JAWS - The teachings herein provide an instrument comprising a forceps. The forceps comprise a hand piece; a tubular member connected to the hand piece; and a jaw assembly connected to the hand piece. The jaw assembly includes a first jaw element and a second jaw element. The first jaw element includes a gripping section and a flexing section. The flexing section includes an arcuate section. The second jaw element opposes the first jaw element and includes a gripping section. The tubular member is moveable onto the arcuate section of the first jaw element so that the flexing section of the first jaw element is flexed and the as assembly is moved into a closed position. The first jaw element, the second jaw element, or both include a stiffening spine so that the as assembly is substantially rigid in the closed position. | 04-28-2016 |
