Some embodiments provide systems, assemblies, and methods of analyzing patient anatomy including providing an analysis of a patient's spine. The systems, assemblies, and/or methods can include obtaining initial patient data, and acquiring spinal alignment contour information. Further, the systems, assemblies, and/or methods can assess localized anatomical features of the patient, and obtain anatomical region data. The system, assemblies, and/or method can analyze the localized anatomy and therapeutic device location and contouring. Further, the system, assemblies, and/or method can output localized anatomical analyses and therapeutic device contouring data and/or imagery on a display.
SYSTEMS, DEVICES AND METHODS FOR TREATING A LATERAL CURVATURE OF A SPINE
A system for correcting a lateral curvature of a spine that can include a plurality of screws configured to be implanted in a plurality of vertebrae, and a plurality of extensions configured to be removably coupled with the plurality of screws. Some embodiments of the plurality of extensions can be curved, bent, angled, and/or offset along at least a portion thereof and can be removably coupled with a screw head of each of the plurality of screws. The system can include a connecting element or rod that is configured to be coupled with the plurality of screw heads. Some embodiments of the system can be configured such that the rod can be guided along the plurality of extensions from the proximal toward the distal end portions of the extensions and into engagement with the plurality of screws to cause the plurality of vertebrae to move laterally.
Universal instrument guide for robotic surgical systems, surgical instrument systems, and methods of their use
Described herein are systems and apparatus of surgical instruments engineered for integration with robotic surgical systems to enhance precision in surgical procedures. Also described herein are methods of using such surgical instruments in performing surgical procedures. The use of such surgical instruments reduce complications arising from misalignment during surgery. The disclosed technology assists in stages of a surgical procedure that require a precise trajectory to be followed. Surgical instrument guides are attached to a universal surgical instrument guide, which is engineered to attach directly or indirectly with a robotic arm of a robotic surgical system. Surgical instruments can then be precisely guided along an axis defined by the universal surgical instrument guide. Individual instruments are easily inserted and removed from the channel of the universal surgical instrument guide, thus allowing a range of instruments to be used throughout a procedure while maintaining the surgical trajectory.
Modular spinal screw yoke inserter
An inserter for attaching a modular yoke to a bone screw and for providing an indication of attachment, comprises a tubular body having a central lumen, distal and proximal ends, and an attachment portion for releasable attachment to a yoke having a bottom opening for receipt of a head of said bone screw. The inserter includes an inner shaft having a distal end configured to be received into the yoke, the shaft being axially movable within the lumen from first to second axial positions in response to the introduction of the bone screw head into the yoke bottom opening. An indicator button supported by the body is movable in response to axial movement of the shaft from a first indicator position indicating the first axial position of the shaft relative to the body to a second indicator position indicating the second axial position of the shaft relative to the body.
Receiving part of a bone anchoring device and bone anchoring device with such a receiving part
A receiving part of a bone anchoring device is provided, where the receiving part includes a first end, a second end opposite to the first end, a central axis extending through the first end and the second end, and a substantially U-shaped-recess adjacent to the first end for receiving a spinal fixation element. The substantially U-shaped recess forms two free legs. The receiving part also includes a bore extending from the first end towards the second end and in communication with the substantially U-shaped recess. A groove is provided in an outer surface of each of the legs, where the groove has a first end and a second end and extends in a circumferential direction in an arcuate shape between the first end of the groove and the second end of the groove. In a plane that includes the central axis and that extends through a center of each leg, a contour of a surface of the groove has at least a first arcuate portion and a second arcuate portion opposing the first arcuate portion, where the contour is substantially free from straight portions.
Pedicle screw system and method
A pedicle screw system and methods of using same, the system including a pedicle screw with a screw head and a rod support housing with a head capture opening surrounded by relief slots. The rod support housing has an interior gripping ridge and an exterior locking groove. Pressing the screw head into the head capture opening results in regions of the rod support housing between the relief slots flexing outwardly to allow the screw head to pass over the gripping ridge, and the regions to cease flexing outwardly after the screw head is seated within the rod support housing. Pressing a locking ring over the head capture opening causes regions of the rod support housing between the relief slots to flex inwardly and allow a locking tab of the locking ring to pass into the locking groove, after which the regions cease flexing inwardly.
PIVOTAL BONE ANCHOR ASSEMBLY WITH BOTTOM LOADED SHANK HEAD AND RESILIENTLY EXPANDABLE RETAINER
A pivotal bone anchor assembly includes a receiver defining a cavity with an upper expansion region and a lower locking region, and a shank having a partial spherical head that is up-loadable into the cavity through a bottom opening. The assembly also includes a resiliently expandable retainer that is positionable within the upper expansion region with a discontinuous partial spherical internal surface and an inwardly facing surface above the discontinuous partial spherical internal surface, and a compression insert having a lower outwardly facing surface configured for side-to-side engagement with the inwardly facing surface and a downwardly facing partial spherical surface for frictionally engaging the head of the shank. The compression insert is positionable in overlapping engagement with the retainer within the receiver with the discontinuous partial spherical internal surface extending above and below a hemisphere of the head of the shank to capture the head within the retainer.
Asymmetric clamp with ultrasonic tissue removal capability
An ultrasonically assisted clamping system and method for extending a spinal support rod system to additional vertebrae of the spine. A clamp assembly and a receptacle assembly securely couple an additional extension rod to an existing spinal support rod. Various embodiments further include an ultrasonic assist for cutting through tissue that may be present in the vicinity of the existing spinal support rods. In some embodiments, the clamp assembly is configured to augment the ultrasonic aspect of the system. The system cuts through and locally removes tissue from and proximate to the spinal support rods where the clamp assembly is to be mounted, without the need for a separate surgical procedure for removing the tissue prior to implantation, thereby providing a secure clamping of the newly implanted extension rod to the existing base spinal support rod.
SCREW PLACEMENT SYSTEM AND VERTEBRAL PEDICLE SCREW PLACEMENT DEVICE
The vertebral pedicle screw placement device of the present application includes a bone drill mechanism and a depth advancing mechanism connected to the bone drill mechanism and used to generate linear reciprocating motion. The bone drill mechanism includes a bone drill driving device and a clamping mechanism connected and driven by the bone drill driving device. The present application provides the driving force of the linear reciprocating motion of the bone drill mechanism through a depth advancing mechanism, and combines the driving control of the clamping mechanism by the bone drill driving device. The clamping mechanism is used to clamp the guide pins, reamers, taps, vertebral pedicle screws, etc. required in the operation, so as to realize the screw placement in the operation, improve the operation efficiency and the accuracy of the screw placement, and avoid possible accidental injuries in the manual screw placement process in the prior art.
