A surgical instrument includes an elongated body operably connected to a jaw member and a blade. The elongated body includes an inner tube and an outer tube configured to move laterally with respect to one another. A drive arm has a first end engaged to the outer tube and a second end pivotably coupled to the jaw member configured to move laterally in tandem with the outer tube such that motion of the outer tube in a first direction pulls the jaw member away from the blade, and motion of the outer tube in a second direction pushes the jaw member towards the blade. The drive arm includes a semi-rigid material configured to flex when compressed, such that flexion of the drive arm can offload excess force exerted by the outer tube on the jaw member.

A surgical instrument may comprise a chassis, a shaft coupled to the chassis at the proximal end of the shaft, an end effector coupled to the shaft at the distal end of the shaft, a force transmission mechanism coupled to the chassis, and an actuation element connected between a lever arm of the force transmission mechanism and the end effector. The force transmission mechanism includes a worm drive, and the lever arm comprising a first end and a follower member at the first end of the lever arm, wherein the follower member is engaged with the worm drive and is configured to be driven by the worm drive. Rotational movement of the worm drive imparts translational movement to the actuation element via the lever arm, and the lever arm slides along a generally linear direction relative to the chassis to impart the translational movement to the actuation element.

A surgical tissue grasper includes a handle assembly having a trigger, an endoscopic assembly, and a jaw assembly. The endoscopic assembly includes an outer tube and a driver. The driver is movable within the outer tube and operatively coupled to the trigger. The jaw assembly includes a stem detachably coupled to the driver, and a pair of jaws extending distally from the stem such that actuation of the trigger transitions the pair of jaws between spaced apart and approximated configurations to enable clamping of tissue. Each jaw of the pair of jaws includes a gripping portion and an outer support. The gripping portion is configured to engage tissue. The outer support is disposed outward of the gripping portion and coupled to an end portion of the gripping portion to enable flexing of the gripping portion or the outer support when a clamping force applied to tissue exceeds a predetermined threshold.

A system includes a medical device and a charging device. A sterile barrier may be interposed between the medical device and the charging device. The medical device includes an integral power source and an active element. The charging device is configured to charge the integral power source. The charging device may charge the integral power source through direct contact between features of the charging device and features the medical device. The charging device may alternatively charge the integral power source wirelessly, such as through inductive coupling. The medical device may include conductive prongs that are retained by the charging device. The charging device may physically couple with the medical device via magnets. The medical device and the charging device may be provided together in a sterile package as a kit. The kit may also include a reclamation bag to facilitate reclamation of electrical components.

Medical devices including a housing, an actuator, a body having a passageway extending through the body, a drive shaft extending through the passageway, and a clip coupled to the body and the drive shaft to fix the body relative to the drive shaft. The medical device further including features to couple the clip to at least one of the body and/or the drive shaft such that back out of the clip is inhibited.

Provided is an instrument for surgery and, more specifically, to an instrument for surgery which can be manually operated in order to be used for laparoscopic surgery or various types of surgery.

An ultrasonic surgical instrument includes an inner tube, an outer tube, an ultrasonic blade, and a clamp member pivotably moveable relative to the ultrasonic blade. The ultrasonic blade is acoustically coupled to an ultrasonic transducer. The clamp member pivotably movable relative to the ultrasonic blade between an open configuration and an approximated configuration with respect to the ultrasonic blade, wherein the clamp member is pivotably coupled to the inner tube, wherein the clamp member is pivotably coupled to the outer tube, and wherein movement of the outer tube relative to the inner tube between the first position and the second position transitions the clamp member between the open configuration and the approximate configuration.

Forceps can include a drive pin, an outer tube, a first jaw, a second jaw, and an inner shaft. The outer tube can extend along a longitudinal axis. The first jaw can be pivotably connected to the outer tube. The first jaw can include a first flange that can be located at a proximal portion of the first jaw. The first flange can include a first chamfered edge configured to limit extension of the first flange laterally beyond an outer surface of the outer tube when the first jaw is in a closed position. The inner shaft can be located within the outer tube and can extend along the longitudinal axis.

Forceps can include an outer tube, a first jaw, a second jaw, and an inner tube. The outer tube can extend along a longitudinal axis and can include a pair of outer arms extending from a distal portion of the outer tube. The first jaw can be pivotably connected to the outer tube and the first jaw can include a first flange and a second flange each located at a proximal portion of the first jaw. The first flange and the second flange can each include a proximal portion extending outward of the outer tube when the jaws are in an open position. The proximal portions can be shaped to limit extension of the proximal portions laterally beyond the outer arms.
