An arthroscopic system includes a re-useable, sterilizable handle integrated with a single umbilical cable or conduit. The single umbilical cable or conduit carries electrical power from a power and/or control console to the handle for operating both a motor drive unit within the handle and delivering the RF power to a disposable RF probe or cutter which may be detachably connected to the handle. The RF power delivered to the handle and on to the probe or cutter is typically bi-polar, where the handle includes first and second electrical bi-polar contacts that couple to corresponding bi-polar electrical contacts on a hub of the disposable RF probe or cutter is connected to the handle.

Disclosed herein is a surgical device. The surgical device includes a cutting burr, a flexible/deflectable shaft, an elongated fluted shaft, a sheath, and an outer tube. The cutting burr has a fluted extension. The flexible/deflectable shaft has a distal end and a proximal end, the distal end is configured to be connectable to the fluted extension of the cutting burr. The elongated fluted shaft is configured to be connectable to the proximal end of the flexible shaft. The sheath is configured to receive all or portion of the flexible shaft and the elongated fluted shaft. The outer tube is configured to receive the sheath such that there is enough space for fluid irrigation between the outer tube and the sheath.

A system for intramedullary preparations comprises a directional reamer including a flexible drive shaft having a proximal end and a distal end, and a cutting head operably connected to the distal end of the flexible drive shaft. The system further includes a means of displacing the distal end of the flexible drive shaft and deflecting the cutting head to selectively shape a medullary canal in a bone. A follower sleeve is also include in the system and has a proximal end and a distal end in the form of a collar, with the follower sleeve being configured to accept the flexible drive shaft. The system additionally includes a reaming plunger that extends through the follower sleeve and is positioned adjacent to the flexible drive shaft such that the reaming plunger engages the collar of the follower sleeve to deflect the cutting head.

An orthopedic drill bit that is configurable to form a first bone tunnel having a first bore when inserted through a bone and a second, larger bore as the drill is partially withdrawn from bone to produce a reverse counterbore for accepting an anchor. The drill bit has a shaft with a pivotal cutting tip that is movable from a narrow boring configuration into a wider boring configuration. The drill bit has a body enclosing the shaft that is biased into engagement with the cutting tip. Rotation of the body allow a user to move the cutting tip from the narrower bore configuration used to drill a pilot hole into a wider bore configuration used to drill a reverse counterbore for accepting the anchor.

An anchor delivery system includes both a straight and curved drill guide along with a flexible drill, a flexible obturator and a flexible anchor inserter. The curved drill guide has a distal tip with approximately a 15° bend from the primary axis of the drill guide. Both the drill and the obturator have a reduced diameter section to improve flexibility during passage through the curved drill guide. Additionally, a surface of the inserter shaft has a laser cut pattern which permits flexing of the inserter around the inner diameter of the curved drill guide.

Described herein are various implementations of systems and methods for accessing and modulating tissue (for example, systems and methods for accessing and ablating nerves or other tissue within or surrounding a vertebral body to treat chronic lower back pain). Assessment of vertebral endplate degeneration or defects (e.g., pre-Modic changes) to facilitate identification of treatment sites and protocols are also provided in several embodiments. Several embodiments comprise the use of biomarkers to confirm or otherwise assess ablation, pain relief, efficacy of treatment, etc. Some embodiments include robotic elements for, as an example, facilitating robotically controlled access, navigation, imaging, and/or treatment.

A novel method and instrumentation for insertion of humeral and glenoid total shoulder implant using arthroscopic visualization for bony preparation as well as insertion of components through small incisions. Mini instruments and cannulated guides and reamers are used in order to perform the procedure under direct arthroscopic visualization. For ease of insertion, the components are inserted separately and assembled in situ. Securing the humeral components in place is accomplished with bicortical screw transfixing the central peg of component. Also disclosed are components, parts thereof and instruments used therewith.

The disclosure provides example methods, systems and apparatus for stabilization of a rib. An example method includes: (a) accessing a medullary canal of a rib having a fracture, (b) advancing a guidewire into the medullary canal across the fracture, (c) advancing a delivery catheter containing a stent over the guidewire into the medullary canal and across the fracture, (d) retracting the delivery catheter relative to the stent, and (e) expanding the stent in the medullary canal.

A surgical tool comprises a dilator, a cutter, a retractable brush, and at least one retractable drill. The dilator is configured to dilate tissue of a patient and can be positioned in an undilated configuration or a dilated configuration. The cutter is configured to cut the tissue and is disposed at a distal end of the dilator. The cutter is configured to move between a cutting position when the dilator is in the undilated configuration and a non-cutting position when the dilator is in the dilated configuration. The retractable brush is configured to brush a surface of an anatomical element of the patient to remove matter from the surface. The at least one retractable drill is configured to drill into the anatomical element.

A surgical handpiece system capable of determining a suitable screw length for bone fixation with a bone plate that compensates an initial screw length value based on orientation of the surgical handpiece system during a drilling process. The surgical handpiece system comprising a surgical handpiece including a depth measurement extension and a sensor. The depth measurement extension may be configured to determine a thickness of bone when a drill bit is attached and used to drill through the bone. The sensor may be configured to generate an orientation signal responsive to orientation of the depth measurement extension. The surgical handpiece system also comprises a processor in communication with the sensor and configured to determine the suitable screw length for bone fixation based the sensor.
