An electrosurgical forceps includes first and second shaft members and first and second jaw members extending distally from the respective first and second shaft members. A pivot couples the first and second shaft members with one another such that the first and second shaft members are movable relative to one another between a spaced-apart position and an approximated position to move the first and second jaw members relative to one another between an open position and a closed position. The jaw members are configured to facilitate tissue treatment, tissue division, and blunt tissue dissection.

A compliant mechanism is provided, for extending a rod in a manually controlled instrument and providing clicking haptic feedback, such as in particular in a compliant surgical grasper. The compliant mechanism comprises an inner rod that comprises an upper slit and a lower slit running through a section of the rod, that forma generally S-shaped cut in the rod, such that when ends of the rod are pulled at the S-shaped form allows an extension of the rod in the axial direction by compliant bending; the mechanism comprises a notch placed on the outer surface of the rod, adjacent to a respective slit opening and on the proximal side of the opening, and an outer sleeve enclosing the inner rod, the sleeve having on its inner surface one or more groove or teeth facing the at least one notch on the rod surface, such that when the rod is extended, the notch engages with said groove or tooth to create a clicking haptic feedback.

A surgical stapling device includes a tool assembly having an anvil and a cartridge assembly that are movable in relation to each other between open and clamped positions. The cartridge assembly includes a staple cartridge that can be replaced after each firing of the stapling device to facilitate reuse of the stapling device. The anvil includes a lockout mechanism that prevents operation of the stapling device when the staple cartridge has been previously fired. The lockout mechanism moves from a locked position to an unlocked position in response to movement of the tool assembly from the open position to the clamped position.

A surgical stapling device includes a tool assembly including an anvil and a cartridge assembly that are movable in relation to each other between open and clamped positions. The cartridge assembly includes a staple cartridge that can be replaced after each firing of the stapling device to facilitate reuse of the stapling device. The anvil includes a lockout mechanism that prevents operation of the stapling device when the staple cartridge has been previously fired. The lockout mechanism is adapted to move from a locked position to an unlocked position when the staple cartridge is replaced and the tool assembly is moved from the open position to the clamped position.

A medical device support system including a shaft, an extension arm, and a free rotating ring. The shaft includes an elongated peripheral cavity that defines first and second contact faces at opposite peripheral ends. A hub of the extension arm is pivotably mounted for a range of at least 360 degrees rotation about a rotation axis of the shaft. The at least 360 degrees rotation range is based on a compound of a first rotation range and a second rotation range. The first rotation range is defined by a fixed stop of the hub configured to move between first and second contact faces of a radially outward protruding member of the free rotating ring. The second rotation range is defined by a radially inward protruding member of the free rotating ring configured to move between the first and second contact faces of the elongated peripheral cavity of the shaft.

A medical device support system including a shaft, an extension arm, and a hub mounted to the shaft for pivotable movement of the extension arm about a rotation axis of the shaft. The hub includes a cavity including first and second contact faces, and at least one floating stop movably disposed in the cavity. The hub is pivotably mounted for a range of at least 360-degrees rotation about the rotation axis. The at least 360-degrees rotation range is based on a compound of a first rotation range and a second rotation range. The first rotation range is defined by a first movable amount of the at least one floating stop between first and second stop surfaces fixed relative to the shaft. The second rotation range is defined by a second movable amount of the at least one floating stop between the first and second contact faces of the hub.

A medical device support system including a shaft, extension arm, and floating stop. A guide channel member is fixed to the shaft and includes an elongated cavity that defines first and second contact faces at its opposite ends. A hub of the extension arm is pivotably mounted for a range of at least 360 degrees rotation about a rotation axis of the shaft. The at least 360 degrees rotation range is based on a compound of a first rotation range and a second rotation range. The first rotation range is defined by a fixed stop of the hub configured to move between first and second contact faces of a radially outer portion of the floating stop. The second rotation range is defined by a radially inner portion of the floating stop configured to move between the first and second contact faces of the elongated cavity of the guide channel member.

Devices, systems, and methods for drilling an anatomical element are provided. A drill bit may comprise a coaxial hollow shaft in communication with a plurality of apertures disposed on a surface of the drill bit. A fluid inlet may be in fluid communication with the coaxial hollow shaft via a selectively openable valve. The fluid inlet may be configured to receive pressurized fluid. When the valve is opened, the pressurized fluid may be released into the coaxial hollow shaft, and when at least one of the plurality of apertures is not blocked, the pressurized fluid may be released through the at least one aperture of the plurality of apertures.

Surgical visualization systems and related methods are disclosed herein, e.g., for providing visualization during surgical procedures. Systems and methods herein can be used in a wide range of surgical procedures, including spinal surgeries such as minimally-invasive fusion or discectomy procedures. Systems and methods herein can include various features for enhancing end user experience, improving clinical outcomes, or reducing the invasiveness of a surgery. Exemplary features can include access port integration, hands-free operation, active and/or passive lens cleaning, adjustable camera depth, and many others.

A stop member for use with a surgical stapling device includes a plurality of sections that are releasably coupled to each other. Each of the sections includes a coupling member that can be selectively coupled to a tool assembly of the surgical stapling device to limit an actuation stroke of a drive assembly of the stapling device. Sections of the stop member can be removed from the stop member to change the position of a stop surface of the stop member on the tool assembly to change the effective stroke length of the clamp member.
