A surgical implant comprising a receiver member and deployment member for clamping and sealing tissue of variable thickness, a corresponding applicator tool and surgical system for connecting, sealing, fastening and/or attaching tissue to itself, to other tissue and/or to non-tissue structures, and/or sealing the flow of fluid at and/or between structures such as tissue and vessel structures.

A medical treatment tool includes an elongated insertion section; a grasper supported by a distal end of the insertion section so as to be openable and closable; a generator disposed at a proximal end of the insertion section and generating a force to drive the grasper; a transmitter transmitting the force generated by the generator to the distal end of the insertion section; an amplifier amplifying the force transmitted through the transmitter; and a toggle amplifying and converting the force amplified by the amplifier into a force directed to open or close the grasper.

A medical manipulator includes a trigger lever operated by hands, a shaft that extends from a body in which the trigger lever is provided, and a tip operating unit that is provided at a tip of the shaft. The tip operating unit includes an end effector to which the operation of the trigger lever is mechanically transmitted and in which the operation is performed, and a detection mechanism that detects an operation state of the first input unit.

A surgical stapling instrument comprising an elongate shaft assembly that includes a surgical end effector that is operably coupled thereto by an articulation joint. The surgical instrument may include a first distal articulation driver operably coupled to the surgical end effector and a second distal articulation driver that is coupled to the surgical end effector. At least one driver member may operably engage the first and second distal articulation drivers such that when the first distal articulation driver is moved in a distal direction, the least one driver moves the second distal articulation driver in a proximal direction and when the first distal articulation driver is moved in the proximal direction, the at least one driver member moves the second distal articulation driver in the distal direction.

An instrument including a first arm and a second arm. The first arm includes a first jaw including a first distal end. The second arm includes a second jaw including a second distal end. One of the first jaw and the second jaw includes a first protrusion. When the instrument is moved into a closed configuration, the first distal end and the second distal end make contact, which occurs after the first protrusion and the opposing jaw make contact.

A detector-equipped treatment tool including: a distal-end treatment portion that applies a force to and treats biological tissue; a proximal-end portion that supports the distal-end treatment portion so as to be relatively movable; a detector that is disposed in a cavity provided inside of the distal-end treatment portion and detects the force; wiring that is connected to the detector; and a duct that is connected to the distal-end treatment portion and guides the wiring led out of the distal-end treatment portion from the detector in the cavity to the proximal-end portion.

Various embodiments are direct to a surgical instrument comprising and end effector, an articulating shaft and an ultrasonic transducer assembly. The end effector may comprise an ultrasonic blade. The articulating shaft may extend proximally from the end effector along a longitudinal axis and may comprise a proximal shaft member and a distal shaft member pivotably coupled at an articulation joint. The ultrasonic transducer assembly may comprise an ultrasonic transducer acoustically coupled to the ultrasonic blade. The ultrasonic transducer assembly may be positioned distally from the articulation joint.

A surgical end effector includes a clevis and two jaws rotatably coupled to the clevis. A rocking pin in the form of a solid of revolution is pivotally supported by the clevis. The rocking pin may be pivotally supported by the clevis at the midpoint between the first and second ends. The opposite ends of the rocking pin engage the jaws to constrain the jaws to have opposite motions around the axes of rotation of the jaws. The clevis may be coupled to an elongate shaft to provide an endoscopic instrument. The first and second jaws may be electrically isolated from one another for electrocautery and the rocking pin may be formed from a non-conductive material or electrically isolated from the first and second jaws by electrically non-conductive liners. The jaws may be opened and closed by pushing and pulling on wires coupled to the jaws.

A snakelike surgical instrument, comprising a handheld structure (2); an manipulating structure (1) comprising an outer frame (13) hingedly connected to the handheld structure (2) so that the manipulating structure (1) has a rotational degree of freedom (R1′) around a first axis and an inner frame (14) hingedly connected to the outer frame (13) so that the manipulating structure (1) has a rotational degree of freedom (R2′) around a second axis, the first axis and the second axis forming an angle; an end unit (4) connected to the handheld structure (2) by means of a connecting component (3) and comprising a tool supporting base (41) and a snakelike structure (40) connected to the tool supporting base (41), the snakelike structure (40) having degrees of freedom of motion (R1, R2) in the same direction as the manipulating structure (1); and a transmission unit (5) comprising a flexible transmission structure connected to the inner frame (14) and the snakelike structure (40). A mechanical transmission mode is used by the snakelike surgical instrument, the motion of a handheld side can be directly transmitted to the end unit (4), complicated force feedback control is avoided, and control is simple.

A medical device may include a plurality of links reciprocally movable between a loose configuration having a first rigidity and a compact configuration having a second rigidity greater than the first rigidity, wherein application of a force to a distalmost link of the plurality of links when the plurality of links are in the loose configuration causes the plurality of links to change orientation relative to one another, and application of the force to the distalmost link when the plurality of links are in the compact configuration does not cause the plurality of links to change orientation relative to one another.
