Disclosed is an apparatus and modular surgical system that allows for a user of modular surgical instruments to manipulate an end effector directly from the instrumentation contained in the handle assembly. A nozzle assembly that is detachable from a handle assembly may include an onboard circuitry board that allows for the RF generator to attach directly to the nozzle assembly and supply RF energy to the end effector, while also interfacing with a microprocessor of the handle assembly. In some aspects, the unique circuitry of the nozzle assembly also allows for shaft rotation while still supplying proper energy and functionality to the end effector.

An interchangeable tool assembly is disclosed. The interchangeable tool assembly includes a first jaw configured to support a staple cartridge during a first time period and a radio-frequency cartridge during a second time period. A second jaw is coupled to the first jaw. A surface of the second jaw defines a plurality of staple forming pockets configured to form staples driven from the staple cartridge. An electrically insulative material covers segments of the surface of the second jaw other than the staple forming pockets. The staple forming pockets define at least one return path for radio-frequency energy delivered by the radio-frequency cartridge.

A surgical instrument including a surgical end effector and a threaded rotary input shaft. An actuator member is in operable engagement with the surgical end effector and is in selective threaded engagement with the threaded rotary input shaft such that when the actuator member is in an engaged configuration, rotation of said threaded rotary input shaft causes the actuator member to move axially to impart an actuation motion to the surgical end effector and when the actuator member is in a disengaged configuration, rotation of the threaded rotary input shaft will not be imparted to the actuator member. A switch may be employed for selectively moving the actuator between the engaged and disengaged configurations. A locking system may be employed for preventing axial movement of the actuator member when the actuator member is in the disengaged configuration.

A device comprises an outer tube defining a longitudinal axis and comprising an aperture near a distal end thereof; a cutting element disposed within the outer tube and configured for rotation and movement across the aperture along the longitudinal axis, the cutting element comprising an engagement feature at a distal end thereof; and a distal tip comprising a tapered distal end and a proximal end that comprises a mating feature. The cutting element may be configured to rotate and cut tissue as it moves along the longitudinal axis across the aperture until the engagement feature at least partially engages the mating feature of the proximal end of the distal tip and entrains the distal tip in oscillation along the longitudinal axis and/or rotation.

Disclosed herein are various systems and methods for facilitating control of a tool or tools. The systems can allow a user to control multiple degrees of freedom. One such system allows a user to control multiple degrees of freedom of two tools simultaneously. Another such system allows a user to control multiple degrees of freedom with a single hand. Frames and rails for supporting and/or constraining movement of a tool or tools are also described herein.

A surgical stapling apparatus can comprise, in various instances, a staple cartridge comprising staples removably stored therein, a firing system configured to eject the staples from the staple cartridge, and an electric motor configured to drive the firing system. The stapling apparatus can further comprise a lockout system configured to, one, detect whether a first jaw is in an open position or a closed position relative to a second jaw and, two, prevent the electric motor from driving the firing system when the first jaw is not in a closed position.

A scalpel body including an attachment for a removable blade, a spray head adapted to operatively deliver a surgical liquid as a spray proximal to a removable blade, and an external connection for allowing the spray head to be connected to an external supply of surgical liquid. A release mechanism allows for selective release of the spray, proximal to the blade.

An interventional device for cutting tissue at a targeted cardiac valve, such as a mitral valve. The interventional device includes a catheter having a proximal end and a distal end. A cutting mechanism is positionable at the distal end, such as by routing the cutting mechanism through the catheter to position it at the distal end. The cutting mechanism includes one or more cutting elements configured for cutting valve tissue when engaged against the tissue. A handle is coupled to the proximal end of the catheter and includes one or more controls for actuating the cutting mechanism.

A flexible assembly of a motor driven surgical system may include a flexible shaft circuit strip and a knife bar having a first laminated plate disposed along a first side of the circuit strip and a second laminated plate disposed along a second side of the circuit strip. The knife bar may reciprocate along a longitudinal axis of the circuit strip. Each laminated plate may be composed of a pair of laminated plates. The flexible assembly may include a first leaf spring disposed between the first side of the circuit strip and the first laminated plate, and a second leaf spring disposed between the second side of the circuit strip and the second laminated plate. The flexible assembly may be disposed within at least a portion of a distal portion of an articulating shaft and at least a portion of an articulation connector of the surgical device.

The invention provides a pair of dual-purpose forceps, comprising a first forceps body and a second forceps body. When the first forceps body is connected with the second forceps body by means of a first pressurizing connecting member and a second pressurizing connecting member, a first handheld member and a second handheld member move towards each other, and a first pressurizing functional member and a second pressurizing functional member also move towards each other to complete pressurizing; when the first forceps body is connected with the second forceps body by means of a first opening connecting member and a second opening connecting member, the first handheld member and the second handheld member move towards each other, and a first opening function member and a second opening function portion face away from each other to complete opening. The dual-purpose forceps is simple in structure and is operated conveniently so that the double-purpose forceps can switch freely between opening and pressurizing functions conveniently and quickly.
