ARTICULATING PITUITARY RONGEUR FOR USE WITH A CANNULA
A pituitary rongeur medical instrument has jaws that can controllably articulate radially from a longitudinal axis of a shaft assembly of the pituitary rongeur and beyond a perimeter of a cannula during use. The pituitary rongeur is characterized by a handle, a shaft assembly defining a proximal end extending from the handle, a distal end, and a longitudinal axis, with the jaws pivotally connected to the distal end of the shaft assembly for articulating radial movement of the jaws relative to the longitudinal axis of the shaft assembly, a jaw controller associated with the shaft assembly and configured to controllably close and open the jaws, and an articulation controller associated with the shaft assembly and configured to controllably articulate the jaws. The handle is formed by a handgrip portion configured to receive a palm of a user and a lever portion with a finger loop configured to receive fingers of the user.
VERTEBRAL ENDPLATE SHAVER WITH HEIGHT ADJUSTABLE BLADES
A vertebral endplate preparation (decorticating) tool has height adjustable blades at a distal end of a shaft assembly for decorticating/shaving vertebral endplate material from spinal vertebrae, translates axial movement of a control rod of the shaft assembly of the vertebral endplate preparation tool with height adjustable blades into radial blade height change (extension and retraction) through a controller of a handle assembly. The blades may also be configured for collecting and removing shaved vertebral endplate material. The blades controllably move outward radially from the distal end of the shaft assembly and controllably move inward radially into the distal end of the shaft assembly upon manipulation of the controller. Radial blade extension and retraction from the distal end may be accomplished via mutual angled dovetail features of the blades and the distal end, or via pins of the distal end of the shaft assembly situated in angled slots of the blades.
System and methods for nerve monitoring
A system and related methods for performing nerve detection during surgical access using ultrasound testing during surgery.
Surgical instrument and method
A surgical instrument includes a first member defining an axis and including a cutting surface. A second member includes a cutting surface that is rotatable relative to the first member. A third member includes an outer surface. The cutting surface of the second member is rotatable relative to the outer surface to transfer the cut tissue along the axis. Systems and methods are disclosed.
Intraoperative fluoroscopic registration of vertebral bodies
A method for the fluoroscopic registration in real time for placement of pedicle screws or the like during spinal surgery, comprising creating a lateral image in which a pedicle has appropriate anatomic contour and superior endplate, advancing a pin into the pedicle starting in the posterior cortex and moved far enough into the pedicle to anchor the pin, rotating the fluoroscopy to obtain an AP image of the pedicle which is moved to render the pin to be neutral in a cephalad to candad direction, and positioning a pedicle screw in the pedicle following 2D contour mapping generated by manual or automated templating.
DEVICES AND METHODS FOR STABILIZING TISSUE AND IMPLANTS
An implant for repairing a joint between a first bone and a second bone includes a first section constructed of a substantially rigid material and a graft constructed of soft tissue having a first end and a second end. The first section has a first end surface configured for positioning against the first bone. The graft is configured for stabilizing the first section relative to the first bone. A first fastener is configured for mounting to the graft and the first section to anchor the graft to the first section. A second fastener is configured for mounting to the graft and the first bone to anchor the graft to the first bone.
Percutaneous disc clearing device
A discectomy tool comprising: a) a cannula having an outer surface having a longitudinal bore therein, a proximal end and a distal end; b) a steering wire disposed in the longitudinal bore; c) a flexible, hollow transmission shaft disposed in the cannula, the shaft having a throughbore, a proximal end portion, a distal end portion and an outer surface having a thread extending therefrom; d) an irrigation source fluidly connected to the throughbore; e) a cutting tip attached to the distal end portion of the transmission shaft.
ASSEMBLIES, SYSTEMS, AND METHODS FOR A NEUROMONITORING DRILL BIT
Assemblies, systems, and methods are directed at a neuromonitoring bone drill bit. The assembly may include a surgical bone drill bit, a neuromonitoring connection in electrical communication with the drill bit, and a shield extending over a distal end of the drill bit. The shield may be configured to withdraw proximally as the drill bit is advanced into a subject's bone. The assembly may be connected to a surgical drill and used in a surgical spinal procedure. In operation, the assembly may be advanced to a subject's bone at a surgical site and the drill bit may rotate into the subject's bone. In response, the shield may engage the bone and the drill bit may be advanced with respect to the shield. The shield may electrically insulate tissue from electrical current passing through the drill bit as it is inserted at the surgical site.
Tool assembly, systems, and methods for manipulating tissue
Tool assemblies, system, and methods for manipulating tissue and methods for performing a surgical procedure on a vertebral body adjacent soft tissue. A manipulator moves an end effector, and a screw is coupled to the end effector. A sleeve is disposed coaxially around the screw, and the screw and the sleeve are releasably engaged to one another. A navigation system is configured to track the vertebral body, and one or more controllers control the end effector to advance the screw relative to the sleeve along an insertion trajectory defined with respect to a surgical plan. The screw disengages the sleeve during advancement, and the screw is secured to the vertebral body. A distal working portion of the screw may be freely slidable through a distal end of the sleeve when disengaged. The screw may be a tap marker removably couplable with a tracking device of the navigation system.
MINIMALLY INVASIVE SPINAL INSTRUMENT AND METHOD FOR USE OF SAME
A minimally invasive spinal instrument and method for use of the same are disclosed. In some embodiments, a body includes an outer shaft and an inner shaft. A passageway accepts the inner shaft such that the outer shaft at least partially encloses the inner shaft. Each of the outer shaft and the inner shaft have spaced rings with locking grooves interleaved therewith. Each set of locking grooves is sized to accept a clamp such that the spaced rings mitigate longitudinal sliding of the clamp. A locking knob selectively secures the outer shaft and inner shaft thereto. A tip is removably secured to the inner shaft. In a single shaft configuration, in response to the locking knob being selectively disengaged from the outer shaft, the inner shaft and the locking knob are separated from the outer shaft such that the passageway is accessible to accept a metallic wire therethrough.
