The present disclosure includes apparatuses for a surgical handle assembly. An example apparatus includes a reloadable cartridge assembly and a surgical handle assembly including a spring positioned in the surgical handle assembly at a proximal end of a toothed rack. Proximal movement of the toothed rack causes the spring to be compressed and allows for complete opening of the reloadable cartridge assembly.

A robotic surgical tool is disclosed. The robotic surgical tool can comprise an end effector comprising a firing member; a drive system responsive to a motor-driven input; and a proximal housing comprising a retraction mechanism. The retraction mechanism can comprise a control responsive to a manual input. The control can be rotatable in a first direction through a retraction motion and rotatable in a second direction through a reset motion. The retraction mechanism can further comprise a clutch coupled to the control. The clutch can be configured to drivingly engage the drive system as the control rotates through the retraction motion to supply a proximal retraction stroke to a firing bar and drivingly disengaged from the drive system as the control rotates through the reset motion to prevent any displacement of the firing bar by the retraction mechanism until the control is reset for a subsequent retraction motion.

An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, “ultra-MIS” techniques.

A surgical retractor includes a body portion and first and second retractor arms operatively coupled thereto. The body portion includes a rotatable knob, a first blade holder, and a first blade. The first blade is configured for axial displacement with the first blade holder and angulation relative to the first blade holder about a first axis. The first and second retractor arms include respective second and third blades detachably secured thereto. The first and second retractor arms are transitionable between an approximated configuration and a spaced apart configuration. The second and third blades are configured to angulate about respective second and third axes that are defined by the respective first and second retractor arms.

An impactor according to an embodiment of the present invention comprises an adapter detachably coupled to a rotary power tool, wherein the adapter includes: a case part; a tool coupling part receiving a rotational force from the rotary power tool; a first rotating part rotating in association with rotation of the tool coupling part in only one direction among rotation directions of the tool coupling part; a striking part transfer part rotating in association with rotation of the first rotating part; a striking part which is moved, while compressing a first spring, in a first direction by rotation of the striking part transfer part and then moved in a second direction opposite to the first direction by a restoring force of the first spring; and a force transfer part moved in the second direction by contact with the striking part.

A device and method is provided herein for esophageal impingement of a patient's aorta. The device may be inserted into a patient's esophagus and positioned at the location where the esophagus passes over the patient's aorta. In this position, an actuation device is used to apply pressure to the patient's aorta through their esophagus to impinge or occlude the aorta to stop or significantly reduce hemorrhaging. A manually operable actuator handle enables a physician to manipulate a head assembly of the device through three distinct degrees of freedom of movement so as to control placement and direction of force against the patient's esophagus and, in turn, their aorta.

A method of reducing tricuspid valve regurgitation is provided, including implanting first, second, and third tissue anchors at respective different first, second, and third implantation sites in cardiac tissue in the vicinity of the tricuspid valve of the patient. The geometry of the tricuspid valve is altered by drawing the leaflets of the tricuspid valve toward one another by applying tension between the first, the second, and the third tissue anchors by rotating a spool that (a) winds therewithin respective portions of first, second, and third longitudinal members coupled to the first, the second, and the third tissue anchors, respectively, and (b) is suspended along the first, the second, and the third longitudinal members hovering over the tricuspid valve away from the annulus of the tricuspid valve. Other embodiments are also described.

Embodiments include an end effector including an anvil, the anvil having an anvil face, an anvil blade channel defined by the anvil face, a first pocket row of first row staple pockets, a second pocket row of second row staple pockets, a third pocket row of third row staple pockets, a fourth pocket row of fourth row staple pockets, a fifth pocket row of fifth row staple pockets, a sixth pocket row of sixth row staple pockets, a cartridge having a cartridge face defining a cartridge blade channel, the cartridge being configured to retain a plurality of staples, and a blade, the blade having a cutting edge, where the blade is movable from a first position at a distal end of the cartridge to a second position at a proximal end of the cartridge.

A catheter may include an elongate body extending from a proximal end to a distal end and defining a lumen; a push member mechanically coupled to the proximal end of the elongate body; and a slidable push grip disposed about an outer perimeter of the push member. The slidable push grip is controllably engageable with the push member. When the slidable push grip is in an engaged state with the push member, the slidable push grip transmits an axial force to the push member to enable the push member to transmit the axial force to the elongate body. When the slidable push grip is in a disengaged state with the push member, the slidable push grip is movable axially in at least one direction along a length of the push member while transmitting substantially no axial force to the push member.

This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, “ultra-MIS” techniques.
