| 20090145326 | SPLIT RAIL TROLLEY SYSTEM - An apparatus for removing a wheelset from a railroad vehicle includes a frame configured for motion with respect to the railroad vehicle. The apparatus also includes a lifting yoke cooperatively associated with the frame. The yoke is configured to engage flanges of the wheelset. The apparatus further includes at least one lifting screw interposed between the frame and the lifting yoke, such that upon rotation of the at least one lifting screw, the yoke may be raised and lowered to selectively engage the flanges of the wheelset. A “universal” lifting yoke can include a first portion which engages the at least one lifting screw, a set of extendable transverse members having outward ends, and flange-engaging blocks secured to the outward ends of the extendable transverse members and configured to engage the flanges of the wheelset. The extendable transverse members and the flange-engaging blocks can be cooperatively configured and dimensioned to engage substantially all anticipated wheelsets expected to be encountered in a given application. The “universal yoke” can be employed with screw-actuation, or with other types of actuating members. | 06-11-2009 |
| 20100089973 | SURGICAL INSTRUMENT WITH PIVOTABLE JAW MEMBER - A surgical instrument for surgically joining tissue is disclosed. 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. | 04-15-2010 |
| 20100094315 | Dissection Tip And Introducer For Surgical Instrument - The present disclosure describes a surgical fastener applying apparatus that includes an elongate body portion having proximal and distal ends, an end effector including a first movably coupled to a second jaw that is positioned at the distal end of the elongate body portion, and an introducer member. The introducer member has proximal and distal portions, and is configured and dimensioned for releasable connection with the end effector. The introducer member is at least partially formed from a flexible material, and is configured and dimensioned to separate target tissue from collateral tissue prior to positioning of the target tissue between the first and second jaws of the end effector. | 04-15-2010 |
| 20100213240 | SURGICAL STAPLING APPARATUS WITH CURVED CARTRIDGE AND ANVIL ASSEMBLIES - A surgical instrument is designed for clamping, cutting, and/or joining tissue. This surgical instrument includes a handle portion, an elongate portion extending distally from the handle portion, first and second jaw members disposed adjacent a distal portion of the elongated portion, a shaft movable upon actuation of the handle portion, and a knife bar operatively coupled to the shaft. At least one of the jaw members is movable with respect to the other between an open position and an approximated position for engaging body tissue therebetween. The knife bar has a curved profile and moves along at least one of the jaw members upon movement of the shaft. | 08-26-2010 |
| 20100301098 | SURGICAL INSTRUMENT AND METHOD FOR PERFORING A RESECTION - An end effector for use with a surgical instrument comprising an anvil shaft, a first anvil assembly disposed at a distal portion of the anvil shaft and a second anvil assembly mountable on the anvil shaft proximally of the first anvil assembly. Also, a method for performing a surgical procedure is provided including the steps of providing a surgical instrument including a first cartridge assembly and a first anvil assembly having an anvil shaft, approximating the first anvil assembly and first cartridge assembly and ejecting staples from the first cartridge assembly. The method further includes removing the first cartridge assembly from the tubular organ, and inserting a second anvil assembly into the tubular organ to engage the anvil shaft of the first anvil assembly and ejecting staples from a second cartridge assembly towards the second anvil assembly. | 12-02-2010 |
| 20110006102 | SURGICAL INSTRUMENT WITH DOUBLE CARTRIDGE AND ANVIL ASSEMBLIES - An end effector for use with a surgical instrument having a first cartridge assembly configured to deploy a first set of fasteners and a second cartridge assembly disposed distally of the first cartridge assembly. The second cartridge assembly is configured to move between an open position and an approximated position relative to clamp tissue. A central rod extends between the first cartridge assembly and the second cartridge assembly. | 01-13-2011 |
| 20110084112 | Varying Tissue Compression Aided By Elastic Members - The present disclosure relates to surgical fastener applying apparatus, and the application of variable compression to tissue. More specifically, the presently disclosed surgical fastener applying apparatus including a first jaw having proximal and distal ends and including an anvil member, the anvil member extending along a longitudinal axis and including a tissue contacting surface and a second jaw having proximal and distal ends movably coupled to the first jaw, the second jaw including a cartridge member and a channel. The surgical fastener applying apparatus further includes a pair of elastic members positioned between the cartridge member and the channel of the second jaw, the pair of elastic members configured and dimensioned to apply and maintain constant compressive forces to tissue regardless of tissue thickness. | 04-14-2011 |
| 20110178528 | DISPOSABLE CIRCUMCISION DEVICE - A circumcision system for removing excess foreskin from a penis is disclosed and includes includes a housing, an actuation mechanism, and an anvil. The housing has a threaded hole that defines a longitudinal axis and a locking ring. The locking ring has an internal thread. The actuation mechanism extends through the threaded hole and has a series of needles. A suture is removably attached to a distal end of each of the series of needles. Each of the series of needles has a tapered end and a groove through the tapered end configured to accept and detachably retain the suture. A knife is connected to the actuation mechanism. The knife has a circular blade. The anvil has a passage that is co-axially located with the longitudinal axis and an external thread that is configured to be complimentary to the internal thread. The anvil is in the shape of a collar. | 07-21-2011 |
| 20110178536 | SUTURE AND RETAINER ASSEMBLY AND SULU - A suturing system for receiving and retaining a suture is disclosed and includes a suture, at least one retainer, and at least one needle. Each needle is able to receive and removably retain the suture within a groove located in a tapered end. The retainer has a body that defines an aperture therethrough. The shape of the aperture is formed by a central passageway, and a pair of diametrically opposed slots extending radially outward from the central passageway. The central passageway is sized to allow passage of the needle therethrough. Each slot defines a tortured path section that permits passage of the suture in a first direction and inhibits passage of the suture in a second direction. | 07-21-2011 |
