    Abstract: An assembly tool for facilitating assembly of a surgical instrument includes a handle, a neck extending from the handle, and a portion of or an entire pivot pin engaged with the neck via a frangible connection. The pivot pin is engagable with the surgical instrument. The frangible connection is configured to break upon application of stress thereto above a threshold, thereby separating the pivot pin (or portion thereof) from the neck. A method of assembling using such an assembly tool includes positioning a component of a surgical instrument for receipt of a pivot pin, manipulating the assembly tool to operably engage the pivot pin with the component, and manipulating the assembly tool to apply stress to the frangible connection to break-off the pivot pin (or portion thereof) from the assembly tool along the frangible connection.

    Abstract: A cleaning fixture for a surgical instrument includes a handle receiving portion configured to receive a housing of a surgical instrument, a shaft receiving portion configured to receive a shaft and an end effector assembly of the surgical instrument, and a knife actuation assembly movably coupled to the handle receiving portion or the shaft receiving portion. The shaft receiving portion extends distally of the handle receiving portion. The knife actuation assembly is configured to selectively actuate a knife trigger assembly of the surgical instrument to advance a knife of the surgical instrument between jaw members of the end effector assembly thereof.

    Abstract: A method of disassembling a surgical instrument for reprocessing, includes accessing an interior housing of a surgical instrument to expose a slider assembly, an elongated outer shaft including a drive plate and knife assembly extending therethrough, and a torsion spring of the surgical instrument. The method further includes grasping an upper leg of the torsion spring to disengage the upper leg from a slot defined within the drive plate, disengaging the drive plate from the slider assembly, and removing the torsion spring from the slider assembly.

    Abstract: A surgical instrument includes a housing having a rounded barrel with a distal end and proximal end configured to seat within a palm of a user. A shaft extends from the distal end of the barrel and supports an end effector at a distal end thereof including first and second jaw members. A rotating assembly is disposed on the barrel and is actuatable to rotate the jaw members. A jaw actuation assembly is disposed on the barrel and is actuatable to move the jaw members between open and closed positions. An energy activation assembly is disposed on the barrel and is actuatable to supply electrosurgical energy to the jaw members. A knife actuation assembly is disposed on the barrel and is actuatable to cut tissue disposed between the jaw members.

    Abstract: A handle assembly includes a stationary handle having a first switch, a second switch, and a movable handle coupled thereto. The second switch is movable between a first position and a second position. The movable handle is movable relative to the stationary handle between a spaced position and an approximated position, in which the movable handle actuates the first switch. A portion of the movable handle is configured to contact the second switch when the second switch is in the first position to prevent the movable handle from actuating the first switch.

    Abstract: A surgical instrument includes a shaft defining a lumen, an end effector assembly disposed at the distal end portion of the shaft, a drive plate, a first electrical wire, and a wire guide. The end effector assembly includes a first electrically-conductive tissue-treating surface. The drive plate extends through the lumen of the shaft and operably engages the end effector assembly such that movement of the drive plate through the lumen of the shaft manipulates the end effector assembly. The first electrical wire also extends through the lumen of the shaft and is configured to supply energy to the first electrically-conductive tissue-treating surface. The wire guide is engaged to a distal portion of the drive plate and is configured to move through the lumen of the shaft in conjunction with the drive plate. The wire guide is also configured to receive the first electrical wire.

    Abstract: Methods and devices are described for the design and manufacturing of a knife with a robust cutting edge profile for use in surgical procedures. The cutting edge profile may be defined by a combination of a cutting edge angle and a radius of the cutting edge tip. In some embodiments, the cutting edge profile may be defined by a combination of a web thickness profile and a radius of the cutting edge tip. Numerical ranges are identified for each of the various geometric parameters which may define a cutting edge that provides sufficient knife sharpness over many cutting repetitions. In some embodiments a medical device, which implements a knife with a cutting edge, for use in surgical procedures is described. Methods for forming a knife with a cutting edge including a cutting edge angle, a cutting edge tip radius, and/or a web thickness profile are described.
