A connection device for surgical instruments includes a housing, a head part coupling which is arranged at the housing and is configured for a mechanical coupling of a head part. The head part coupling includes a pin element, which is configured such that the head part can be fixed to the housing in a non-displaceable manner. The pin element is fixed non-detachably to the housing via a weld seam. A surgical instrument includes the connection device and an accessory, which is guided through the head part. A process fixes the connection device with the pin element non-detachably fixed to the housing by a laser welding process.

A medical instrument comprises an instrument control surface configured to mate with an instrument sterile adapter to receive input drive forces through the sterile adapter to control actuation of the surgical instrument, the instrument control surface comprising a first opening defined in the instrument control surface. A latch structure of the instrument comprises a locking surface configured to engage a latch arm in response to the latch arm being received in the opening, wherein in an engaged state of the latch arm with the locking surface the medical instrument is attached to the instrument sterile adapter and the latch structure prevents movement of the latch arm in a first direction. A latch release is moveable in the engaged state of the latch arm with the locking surface to exert a force causing movement of the latch arm in a second direction to disengage the latch arm from the locking surface.

A method is disclosed. The method includes delivering staples from a surgical staple cartridge of a surgical instrument to a first tissue during a first procedure; removing the surgical staple cartridge from the surgical instrument; and delivering radio-frequency energy from a radio-frequency cartridge of the surgical instrument to a second tissue during a second procedure.

A surgical instrument includes a hand piece having a fixed branch and a displaceable branch for actuating a first tool and/or second tool, a guide device in which a force transmission device is arranged to be displaceable longitudinally and/or rotationally, the force transmission device coupled, on the proximal side, to the fixed branch and/or displaceable branch and coupled, on the distal side, to the first tool and/or second tool, and a connection device on which the guide device can be coupled to the hand piece in an insertable and detachable manner by a coupling simultaneously providing a holding force for holding the guide device in the connection device, a bipolar electrical contact on the distal side of the hand piece for parts of the instrument requiring energy, and degrees of freedom for longitudinal and/or rotational movement of the guide device and/or force transmission device.

Apparatus, systems, and methods for achieving thermally-induced renal neuromodulation by intravascular access are disclosed herein. One aspect of the present application, for example, is directed to apparatuses, systems, and methods that incorporate a treatment device comprising an elongated shaft. The elongated shaft is sized and configured to deliver a thermal element to a renal artery via an intravascular path. Thermally-induced renal neuromodulation may be achieved via direct and/or via indirect application of thermal energy to heat or cool neural fibers that contribute to renal function, or of vascular structures that feed or perfuse the neural fibers.

A robotic surgical system employing a treatment catheter (30) (e.g., a thermoablation catheter or a cyroablation catheter), and an articulated robot (40) including a the linkages for navigating the treatment catheter (30) within an anatomical region. The robotic surgical system further employs a robot controller (41) for controlling a navigation by the articulated robot (40) of the treatment catheter (30) along a intraoperative treatment path within the anatomical region relative to the anatomical structure derived from a planned treatment path within the anatomical region relative to the anatomical structure based on a registration between the articulated robot (40) and a preoperative image (21a) illustrative of the planned treatment path within the anatomical region relative to the anatomical structure.

A multi-functional electrosurgical plasma accessory having a handpiece and an extendable probe assembly. The extendable probe assembly has a shaft member, a tube, an electrode, a spacer and a collet. The shaft member and tube each may be formed of a plurality of structures assembled together, each may be of a single unitary design, or both together may be of a single unitary design. The shaft member has an interior channel, a distal end and a proximal end comprised of a neck portion at the distal end of the shaft member, a grip. The elongated portion of the shaft is movable within the spacer between a first position in which a portion of a distal end of the electrode extends out of the tube and a second portion in which the distal end of the electrode does not extend out of the tube.

A cartridge includes an electrical connection assembly, a first port, a second port, a pumping mechanism, a valve, and a fluid flow sensor. The electrical connection assembly is configured to electrically couple to an electrosurgical unit. The first port is configured to fluidly couple to a fluid source. The second port is configured to fluidly and electrically couple to a surgical instrument. The pumping mechanism is disposed between the first and second ports and is configured to draw fluid from the fluid source and pump the fluid to the surgical instrument. The valve is disposed between the first and second ports and is configured to selectively obstruct the flow of the fluid therethrough. The fluid flow sensor is disposed between the first and second ports and is configured to sense fluid flow therethrough. The fluid flow sensor is configured to electrically communicate with the electrosurgical unit.

A method of contraction of collagenous tissue between urethra and vagina includes positioning an RF active electrode between a urethra and a vagina and delivering RF energy into the collagenous tissue. The method includes using a mechanism to direct the active electrode into the safe position to avoid damage of important structures.

This disclosure relates to surgical instruments with selectively rotating handles. In certain aspects, the surgical device includes a conduit having a longitudinal axis and configured to extend into a body lumen, and a handle coupled to the conduit and configured to selectively rotate relative to the conduit. The handle is coupled to the conduit by a connection including a clutch mechanism, and the handle is configured to rotate in response to a user activation of the clutch mechanism.
