A device is disclosed that includes a bone stent positioned within a bony access channel formed within a vertebra. The bony access channel may extends from an outer end of the vertebra through an endplate. The device includes an end cap attached to a proximal end portion of the bone stent and is configured to, post-operatively, open to allow a reintroduction of a material to a spinal intradiscal space or intervertebral disc and to seal access to the spinal intradiscal space or the intervertebral disc after the reintroduction of the material.

A cup remover instrument assembly for removing an acetabular cup in a revision hip procedure comprising: a positioning member supporting a cutting assembly having a cutting blade and a detachable drive member for selectively rotating the cutting assembly to cut around a cup to detach the cup from a patient's natural acetabulum. In embodiments, the positioning member is sized and configured to operate in a main incision, while the drive member is sized and configured to operate in a portal incision. In embodiments, the cutting blade is detachable for use in selecting blades for cup sizes. In embodiments, the cutting blade is selectively extendable from the cutting assembly. In other embodiments, the cutting blade is hemispherical and is rotated by a power driver.

The disclosed subject matter relates to a system and method for preparing a surface of a bone proximate a joint, in which the preparation includes boring a plurality of arced channels/troughs in the bone surface using an arch drill assembly guided by plural guide bores along a predetermined longitudinal arc. The bored troughs create a scalloped surface on the bone to which an inverse contoured joint insert/implant having cooperating convex ridges engages. The plural guide bores are also defined by the predetermined longitudinal arc which may be circular or helical. The disclosed subject matter minimizes bone removal and allows greater access options for preparing the bone surface.

System and methods for channeling a path into bone include a trocar having a proximal end, distal end and a central channel disposed along a central axis of the trocar. The trocar includes a distal opening at or near the distal end of the trocar. The system includes a curved cannula sized to be received in the central channel, and having a curved distal end configured to be extended laterally outward from the distal opening in a curved path extending away from the trocar. The curved cannula has a central passageway having a diameter configured allow a probe to be delivered through the central passageway to a location beyond the curved path.

Methods of manipulating cancellous bone within a vertebral body. A steerable assembly is directed through an access cannula such that a deflectable portion of the steerable assembly protrudes from the access cannula to within the vertebral body. The steering instrument is actuated from an operating tension mode in which a tension is placed on the control element of the steering instrument to a slack tension mode in which the tension on the control element is released. The steerable instrument may exert substantially zero lateral force on the deformable conduit in the slack tension mode. The steering instrument is moved relative to the deformable conduit positioned within the vertebral body. The steering instrument is actuated to move the steering instrument from the slack tension mode to the operating tension mode in which the deflectable portion may assume a curved configuration not substantially coaxial with a longitudinal axis of the access cannula.

Systems for augmenting a vertebral body. A deformable conduit assembly includes a hub defining an opening, and a deformable conduit within which a steering instrument is removably disposed. The deformable conduit may be curved by the steering instrument. An expandable member assembly includes a catheter tube slidably positioned through the opening of the hub and a cannula handle of an access cannula, and an expandable structure. The deformable conduit may be moved proximally relative to the hub and the expandable member assembly to expose the expandable structure within the vertebral body. The hub may define one or more guiding slots though which one or more arms are slidably positioned. An axial controller may be coupled to a proximal end of the deformable conduit. The axial controller is configured to receive an input to expose the expandable structure by moving the deformable conduit relative to the hub and the access cannula.

Devices, Systems, and Methods for detecting a 3-dimensional position of an object, and surgical automation involving the same. The surgical robot system may include a robot having a robot base, a robot arm coupled to the robot base, and an end-effector coupled to the robot arm. The end-effector, surgical instruments, the patient, and/or other objects to be tracked include active and/or passive tracking markers. Cameras, such as stereophotogrammetric infrared cameras, are able to detect the tracking markers, and the robot determines a 3-dimensional position of the object from the tracking markers.

System and methods for channeling a path into bone include a trocar having a proximal end, distal end and a central channel disposed along a central axis of the trocar. The trocar includes a distal opening at or near the distal end of the trocar. The system includes a curved cannula sized to be received in the central channel, and having a curved distal end configured to be extended laterally outward from the distal opening in a curved path extending away from the trocar. The curved cannula has a central passageway having a diameter configured allow a probe to be delivered through the central passageway to a location beyond the curved path.

A power tool for removing an intervertebral disc and preparing vertebral endplates is described. The power tool may include a cutting element, and the height of the cutting element may be adjustable. The cutting element may be a braided cable and may include one or more beads to enhance the effectiveness of the cable. The cutting element may have a minimum height requirement, which may not be satisfied in patients with a collapsed disc due to degenerative disc disorder. For these patients, also described are bone tamps for increasing the intervertebral distance and providing access to tissues distal to the tamp. One type of bone tamp features an inflatable balloon with an inner lumen. Another type of bone tamp includes an expanding distal end and an inner cannula. Also described is a manual expander scraper tool that is compatible with both types of bone tamp.

A bone material removal device including a cannula, a bone drilling forward tip and a bore widening element including a bone carving portion that slides axially relative to the cannula and extends in a circumferential direction and wherein the axial movement of the bore widening element relative to the cannula brings a carving portions to travel and extend radially in a circumferential direction beyond a surface of the cannula and carve bone from a wall of a bore.
