A rotatable jaw device for use with an endoscope and method of using a rotatable jaw device. The device includes a fork, and two jaws pivotally mounted to the fork. The jaws are movable between a predetermined closed position and a predetermined open position. At least one jaw has at least one protrusion on a surface of the jaw. The at least one protrusion prohibits movement of the two jaws in the opening direction beyond the predetermined open position. One jaw may have an elongated center void defined by twin jaw extensions, and the other jaw may rotate within the elongated center void when the two jaws move toward the predetermined closed position.

A treatment tool includes an end effector, an elongated tubular shaft part, a first deflection part having a proximal end connected to a distal end of the tubular shaft part, a second deflection part having a proximal end connected to a distal end of the first deflection part and having a distal end connected to a proximal end of the end effector, and an operation part configured to operate the end effector, in which, when the first deflection part is deflected with respect to an axis of the tubular shaft part, the second deflection part is deflected to an opposite side with respect to the axis and a distal end of the end effector moves on the axis.

A surgical instrument includes a shaft having a proximal end and a distal end and end effector coupled to the distal end of the shaft. An electrical transmission conduit extends along the shaft from the proximal end to the distal end and is configured to deliver electrical energy to energize the end effector. A connector assembly electrically couples the electrical transmission conduit to the end effector, and the end effector is pivotably coupled to the connector assembly. In another aspect, a surgical instrument includes a pin, an electrically conductive connector including a contact portion and an attachment, the contact portion surrounding the pin. An electrical conduit is electrically coupled to the attachment of the connector. An electrically conductive jaw including an aperture is pivotable around the contact portion, and the contact portion electrically contacts the jaw at the aperture of the jaw.

A device and method is provided herein for esophageal impingement of a patient's aorta. The device may be inserted into a patient's esophagus and positioned at the location where the esophagus passes over the patient's aorta. In this position, an actuation device is used to apply pressure to the patient's aorta through their esophagus to impinge or occlude the aorta to stop or significantly reduce hemorrhaging. A manually operable actuator handle enables a physician to manipulate a head assembly of the device through three distinct degrees of freedom of movement so as to control placement and direction of force against the patient's esophagus and, in turn, their aorta.

An ultrasonic surgical instrument and method of deflecting an end effector includes the end effector having an ultrasonic blade, a shaft assembly defining a longitudinal axis, and a body assembly. The shaft assembly has an articulation section configured to articulate from a straight configuration to an articulated configuration and an acoustic waveguide with a flexible waveguide portion positioned within the articulation section. The body assembly proximally extends from the shaft assembly and includes a housing and a shiftable transducer. The shiftable transducer is secured to the acoustic waveguide and configured to generate an ultrasonic energy. In addition, the shiftable transducer assembly is movably mounted relative to the housing and configured to accommodate deflection of the end effector.

An apparatus configured to deliver electrical energy to energize an end effector coupled via a clevis to a shaft of a medical instrument comprises an electrical transmission conduit configured to extend along the shaft from a proximal portion to a distal portion and configured to deliver electrical energy to energize the end effector, and a connector assembly configured to couple to the end effector. The connector assembly comprises an electrically conductive contact portion configured to electrically couple the electrical transmission conduit to the end effector, the electrically conductive contact portion defining a pivot surface about which the end effector is rotatable in a coupled state of the connector assembly to the end effector; and an electrically insulating member configured to electrically insulate the end effector from the clevis in a coupled state of the connector assembly to the end effector.

An end effector assembly for use with a forceps includes a pair of jaw members, a knife assembly, and one or more cam assemblies. One or more of the jaw members are moveable relative to the other about a pivot between open and closed positions. One or more of the jaw members include a knife channel. The pivot includes first and second sections defining a passage therebetween. The knife assembly includes a knife blade and an actuation shaft. The knife blade is disposed distally relative to the pivot. The actuation shaft is configured for slidable translation through the passage to allow selective advancement of the knife blade through the knife channel. The one or more cam assemblies are operably coupled to the one or more moveable jaw members and are actuatable to move the one or more jaw members between the open and closed positions for grasping tissue therebetween.

A device and method is provided herein for esophageal impingement of a patient's aorta. The device may be inserted into a patient's esophagus and positioned at the location where the esophagus passes over the patient's aorta. In this position, an actuation device is used to apply pressure to the patient's aorta through their esophagus to impinge or occlude the aorta to stop or significantly reduce hemorrhaging. A manually operable actuator handle enables a physician to manipulate a head assembly of the device through three distinct degrees of freedom of movement so as to control placement and direction of force against the patient's esophagus and, in turn, their aorta.

Surgical stapling instruments are disclosed comprising a staple cartridge, a firing member, and a cartridge lockout configured to prevent the firing member from being advanced through the staple cartridge if the staple cartridge has been already spent. The stapling instruments further comprise a lockout in the shaft that responds to the cartridge lockout blocking the firing member.

A method is disclosed. The method can comprise obtaining a first staple cartridge and obtaining a second staple cartridge, wherein the first staple cartridge and the second staple cartridge comprise the same length and the same width. The method can further comprise inserting the first staple cartridge into a channel comprising a keyed profile, wherein complete insertion of the first staple cartridge into the channel is prevented by the keyed profile. Additionally, the method can comprise inserting the second staple cartridge into the channel, wherein complete insertion of the second staple cartridge into the channel is permitted by the keyed profile.
