Systems, instruments, and methods for minimally invasive procedures including one or more of fractional resection, fractional lipectomy, fractional skin grafting, and/or fractional scar revision are described. Embodiments include instrumentation comprising a scalpet assembly coupled to a carrier, and the scalpet assembly includes a scalpet array. The scalpet array includes one or more scalpets configured for fractional resection, fractional lipectomy, fractional skin grafting, and/or fractional scar revision. The system includes a vacuum component coupled to the scalpet assembly and configured to evacuate tissue from the a site. The carrier is configured to control application of a rotational force and/or a vacuum force to the scalpet assembly.

A surgical instrument includes a housing, an elongated shaft extending distally from the housing, an end effector assembly, and a trigger assembly. The trigger assembly is disposed in mechanical cooperation with the housing and is configured to longitudinally translate a drive member. The trigger assembly includes a trigger, a gear assembly, a spool, a slider, and a flexible drive member. The trigger is disposed in mechanical cooperation with the gear assembly. The flexible drive member is configured to engage the gear assembly, the spool, and the slider. Movement of the trigger with respect to the housing results in movement of the flexible drive member with respect to the housing and longitudinal movement of the slider with respect to the housing.

A device for implanting a substance into subcutaneous tissue or the dermis of a patient can include a housing, a hypodermic needle, a rod, and a bolt-action rod displacement mechanism. The hypodermic needle can include a lumen that is preloaded with a dermal filler thread. The rod can be configured to fit within the lumen of the hypodermic needle. Upon displacement within the lumen, the rod can cause displacement of the dermal filler thread within the lumen. The bolt-action rod displacement mechanism can be configured to displace the rod within the lumen away from a starting position toward the dermal filler thread.

An instrument that includes forceps. The forceps include a jaw assembly. The jaw assembly includes a first jaw and a second jaw. The first jaw includes a gripping section, and the second jaw includes a gripping section. The jaw assembly is moveable between an open position and a closed position. The first jaw is electrically conductive, the second jaw is electrically conductive, or both the first jaw and the second jaw are electrically conductive. The first jaw includes a first tissue stop that is centered on a medial plane of the first jaw. The tissue stop extends from the first jaw towards the second jaw. The first tissue stop is adapted to block an anatomical feature from extending beyond a proximal end of the gripping section of the first jaw, a proximal end of the gripping section of the second jaw, or both.

A tool driver for use in robotic surgery includes a base configured to couple to a distal end of a robotic arm, and a tool carriage slidingly engaged with the base and configured to receive a surgical tool. In one variation, the tool carriage may include a plurality of linear axis drives configured to actuate one or more articulated movements of the surgical tool. In another variation, the tool carriage may include a plurality of rotary axis drives configured to actuate one or more articulated movements of the surgical tool. Various sensors, such as a capacitive load cell for measuring axial load, a position sensor for measuring linear position of the guide based on the rotational positions of gears in a gear transmission, and/or a capacitive torque sensor based on differential capacitance, may be included in the tool driver.

Surgical devices and methods are provided that utilize an end effector biased to a closed position when an actuator of the device is biased in an uncompressed configuration. End effectors according to the present disclosure can include first and second jaws that can be moved from the biased closed position to an open position by compressing the actuator from the uncompressed configuration and towards a compressed configuration. Various force assemblies and related components are provided that allow the device to achieve two end effector actuation profiles: (1) moving from a closed position and to an open position; and (2) moving from a closed position, to an open position, and back to the closed position. Various structures and methods for operating such devices during a surgical procedure are also provided.

A surgical tool assembly that includes a surgical end effector that has first and second jaws that are movable between a fully open position and a fully closed position relative to each other. A proximal closure member is configured to move through a first closure stroke distance upon application of a closure input motion thereto. A closure reduction linkage operably interfaces with the proximal closure member and a distal closure member such that when the proximal closure member moves through the first closure stroke distance, the closure reduction linkage causes the distal closure member to axially move through a second closure stroke distance that is less than the first closure stroke distance.

The present disclosure relates to a clip apparatus for an endoscope, the clip apparatus having a simple driving part and enabling accurate and easy clip ligation and separation. The present disclosure provides a clip apparatus for an endoscope, the clip apparatus comprising: a handle part having a moving hole formed therein; a handle slider installed so as to be slidable in the handle part through the moving hole; an inner sheath rotatably connected to the inside of the handle part and extending to the outside of the handle part; a wire connected to the handle slider and disposed inside the inner sheath; an outer sheath disposed so as to cover the inner sheath; an outer handle coupled to the outer sheath so as to move the outer sheath along the length direction of the inner sheath; and a clip coupling part connected to one end of the wire and enabling the coupling of a clip.

A method of stapling tissue is disclosed. The method can include obtaining a staple cartridge including a plurality of staples, wherein each staple has a base and a leg extending from the base. The stapling method can also include firing the staples from the staple cartridge, wherein the staples are fired into tissue in a staple line. The staple line can include a first portion having a first flexibility and a second portion having a second flexibility, wherein the second flexibility is different than the first flexibility. A method of stapling tissue can also include adapting an anvil with an anvil plate having an arrangement of staple-forming pockets that differs from the staple-forming pockets in the anvil.

A system for treating tissue includes a clip assembly including a pair of clip arms, proximal ends of the clip arms slidably received within a channel of a capsule to be moved between a tissue receiving configuration and a tissue clipping configuration, and an applicator releasably coupleable to the clip assembly to move the clip assembly between the tissue receiving configuration and the tissue clipping configuration, the applicator including a control member having a plurality of nodes extending therealong, each node having a cross-sectional are larger than a cross-sectional area of a remaining portion of the control member and configured to be coupled to the proximal end of the clip arms, a distal-most one of the nodes severable from a next immediately proximal one of the nodes, when a force exerted thereon exceeds a predetermined threshold value, to release the clip assembly from the applicator.
