A shaper for reaming tissue having a single articulating cutting head can be operably connected to a main shaft. The cutting head can be inverted by rotating the main shaft 180 degrees so that the remaining half-circle of tissue can be removed for a complete discectomy or other surgical procedure. The main shaft can be rotationally locked so that rotation does not occur until the user actuates a release mechanism.

Tools, devices and systems that include a generally cylindrical, hollow shaft, and a suction canister are provided with advantageous interconnectivity features and functions that enable ease of manufacturing, lowered manufacturing costs, and allow for a platform of different shaft embodiments and canister embodiments that may be manufactured in different combinations to form an array of unique instruments. The interconnectivity may be irreversible or reversible, and the connection features maintain an air tight seal between the components. Tools, devices and systems are also provided that include collection functionality that can be employed to manipulate the volume of tissue collected while using a tissue collection feature/function. This may be undertaken to restrict total volume of the collection chamber in a way that allows for continuous suction flow rate to take place while collecting the desired amount of tissue. Containing the tissue to a pre-set volume can enable a user to effectively ascertain the volume of tissue collected.

A surgical instrument includes a first member defining an axis and having a scraping surface configured to scrape tissue. A second member includes a cutting surface that is rotatable relative to the first member. The second member has a maximum length defined by opposite end surfaces of the second member. The end surfaces are each disposed within the first member. A third member includes an outer surface defining at least a portion of a passageway configured for disposal of the scraped tissue. The third member is fixed with the first member. The cutting surface is rotatable relative to the third member to transfer the scraped tissue along the axis. Systems and methods are disclosed.

A handheld surgical device having a working portion that can be covered or uncovered. The working portion of the handheld surgical device can have an advanced position or a retracted position, which can be controlled by one or more switch(s) at the handle portion of the handheld surgical device. The handheld surgical device can also include a shroud that can cover the working portion having a cutting blade driven by a powered motor. The shroud can also have a cutting edge, which is not driven by the powered motor.

A surgical method according to an exemplary aspect of the present disclosure includes, among other things, drying an osteochondral defect using a suction swab. The drying step includes suctioning moisture from the osteochondral defect through the suction swab or communicating a gas to the osteochondral defect through the suction swab.

A medical instrument sheath including an elongated hollow tube having a wall comprised of polymeric material; and at least one electrical lead embedded inside the wall, wherein the at least one electrical lead is configured to be connected with a respective electrode disposed in a member located inside the sheath and extending from a distal end of the sheath.

A tissue removal device including customizable tips and method of use thereof. The tissue removal device may include an outer shaft having a removable tip attached to the outer shaft and a rotatable inner shaft extending through the outer shaft and having a rotatable cutting portion extending from the inner shaft. Disc material may be cut and removed from a surgical area using an auger-like and/or suction mechanism to facilitate the transfer of removed tissue away from the surgical area.

Systems and methods for performing a surgical procedure within a body cavity. The systems include a cannula having a tubular body with ports located at first and second ends thereof, wherein the second end is configured to be inserted into the cavity. The systems further include one or more tools configured to be inserted into the cannula through the ports on the first end, extend through the body of the cannula, and protrude from the ports on the second end. The tools each include a shaft with a working element on a distal end of the shaft, at least portions of which are capable of articulation relative to the shaft, rotation relative to the cannula, and are configured to perform tasks in the cavity. The working element may be produced with an additive manufacturing technique.
