A device for delivering a bone material to a surgical site is provided. The device comprises a body having an upper portion and a lower portion. The lower portion of the body is substantially transverse to the upper portion and has an opening for receiving a bone material. An internal chamber is disposed within the upper portion and the lower portion, and a plunger is slidably disposed in at least the internal chamber of the body. The plunger has a distal end configured for delivering the bone material out of the lower portion of the body, wherein movement of the plunger in a first position toward the lower portion of the body delivers the bone material from the lower portion of the body to the surgical site. Methods of delivering the bone material are also provided.

A tissue displacing and fastening device is provided for manipulating and fastening tissue together. The device includes a tissue displacing elements, which displaces tissue. A fold is formed from the displaced tissue and the tissue is fastened together to secure the fold.

A surgical instrument has an end effector on the end of an elongate shaft extending from a handle. The end-effector has different operations, including grasping, cutting, and sealing and/or coagulating tissue, and one operation is controlled by a switch on the handle proximal end upper surface. The switch is connected to the end-effector to deliver a current to a component in the end-effector. The electrical wire assemblies pass through respective pockets/chambers formed within the handle, an electrical connector contained within each chamber for connecting wires extending from electrodes on the end-effector to wires extending through the handle and on connecting to an electrosurgical generator. The pockets provision within which connectors are contained, one per pocket, prevents insulation damage to wires by connectors, as they are contained within the pockets. The pockets provision pockets side-by-side provides large separation between two connectors, so it is hard for liquid to short the connectors.

An improved surgical instrument having an end effector mounted on the end of an elongate shaft extending from a handle. The end-effector has different operations, including grasping, cutting, and sealing and/or coagulating tissue, and one of the operations is controlled by a drive handle mechanism. The drive handle mechanism includes an actuator, a drive shaft and a spring assembly for transferring movement of the actuator to the drive shaft, which in turn controls the end effector. The drive handle mechanism limits the amount of force transferred from the drive handle mechanism to the end effector, preventing damage to the tissue. As the actuator is operated, the spring assembly transfers the movement of the actuator to the drive shaft and the end effector. At the same time, the spring assembly compresses to absorb some of the force applied. Such configuration prevents the tissue being unintentionally damaged by the end effector.

A surgical stapling apparatus. Various embodiments include a handle assembly that has a movable handle that is movable through actuation strokes relative to a stationary handle housing. An actuation is shaft supported at least in part within the stationary handle housing and is movable in response to manipulation of the movable handle. Various embodiments further include a firing lock out assembly that is configured to selectively prevent longitudinal movement of the actuation shaft in a distal direction. A firing release trigger is supported on the movable handle for travel therewith and is configured to interface with the firing lockout assembly to selectively release the firing lockout assembly to permit the actuation shaft to move longitudinally in the distal direction upon manipulation of the movable handle.

A shaft assembly for a surgical instrument that includes a movable drive member. In at least one form, the surgical instrument includes a spine assembly that is couplable to the surgical instrument and has a surgical end effector coupled thereto by an articulation joint. The shaft assembly in one form includes a proximal firing member and an intermediate firing member that is coupled to a distal firing member. The distal firing member is configured for selective travel through the surgical end effector. At least one articulation driver is coupled to the surgical end effector to apply articulation motions thereto. A clutch assembly interfaces with the primary and intermediate firing members and the articulation driver such that when in an articulation orientation, movement of the drive member results in movement of the articulation driver and when in a firing orientation, movement of the drive member results in movement of the intermediate and distal firing members. A separate articulation motor may be employed to actuate the articulation driver.

A hemostatic device for sealing a puncture of a vessel includes a first tube defining a first lumen, and a malecot coupled to the first tube. The malecot is selectively actuatable from a neutral configuration to a stopper configuration. The hemostatic device also includes a second tube circumscribing at least a portion of the first tube. The second tube at least partially defines a second lumen and a third lumen. The second tube includes a first opening in flow communication with the third lumen and positioned proximally relative to the malecot. The second tube is selectively orientable to at least partially expose a hemocoagulant agent retained in the second lumen.

An instrument that includes forceps. The forceps include a jaw assembly. The jaw assembly includes a first jaw and a second jaw. The first jaw includes a gripping section, and the second jaw includes a gripping section. The jaw assembly is moveable between an open position and a closed position. The first jaw is electrically conductive, the second jaw is electrically conductive, or both the first jaw and the second jaw are electrically conductive. The first jaw includes a first tissue stop that is centered on a medial plane of the first jaw. The tissue stop extends from the first jaw towards the second jaw. The first tissue stop is adapted to block an anatomical feature from extending beyond a proximal end of the gripping section of the first jaw, a proximal end of the gripping section of the second jaw, or both.

An adapter assembly for connecting an end effector to an actuation assembly includes a base member defining a plurality of notches spaced at least partially about a circumference of the base member, a handle supported on the base member and rotatable about a longitudinal axis of the base member, and a latch mechanism supported on the handle assembly and selectively engageable with the base member. The latch mechanism includes a button member and a locking member. The button member is movable between a first position in which the locking member is received within one of the plurality of notches to lock the handle relative to the base member, and a second position in which the locking member is spaced from the plurality of notches to unlock the handle relative to the base member.

A method for engaging and disengaging a surgical instrument of a surgical robotic system including receiving a sequence of user inputs from one or more user interface devices of the surgical robotic system; determining, by one or more processors communicatively coupled to the user interface devices and the surgical instrument, whether the sequence of user inputs indicates an intentional engagement or disengagement of a teleoperation mode in which the surgical instrument is controlled by user inputs received from the user interface devices; in response to determining of engagement, transition the surgical robotic system into the teleoperation mode; and in response to determining of disengagement, transition the surgical robotic system out of the teleoperation mode such that the user interface devices are prevented from controlling the surgical instrument.
