Spinal implant system and methods of use
A method comprises the steps of: imaging a patient anatomy; selecting an implant strategy for at least one bone fastener having a first member; registering the imaging of the patient anatomy with imaging of at least a portion of a robot; engaging the first member with tissue of the patient anatomy via robotic guidance according to the implant strategy; and subsequently, manipulating the patient anatomy. Systems, spinal constructs, implants and surgical instruments are disclosed.
ORTHOPEDIC SCREWS
Self-drilling, self-tapping and self-advancing orthopedic screws are provided. An orthopedic screw includes a relief cut at the tip of the screw that is timed to the distal-most thread at the end of the screw tip to create a wide and sharp cutting edge for the screw.
DEVICES, SYSTEMS AND METHODS FOR USING AND MONITORING SPINAL IMPLANTS
Spinal device/implants are provided, comprising a spinal device/implant and a sensor.
Polyaxial Screwdriver For a Pedicle Screw System
A polyaxial screwdriver for inserting a bone screw in a vertebra. A polyaxial bone screw assembly includes a coupling element. When a screw engaging end of the polyaxial screwdriver is lowered on the head of the bone screw, the complimentary surfaces of the screw engaging end of the screwdriver and the head of the screw self-align. A ratchet mechanism formed in the screwdriver provides progressive and automatic locking of the polyaxial screwdriver to the coupling element and prevents the accidental unthreading from the coupling element. In another embodiment of the polyaxial screwdriver, a collet slides over the outside surface of the upper end of the coupling element and locks on to the coupling element. In yet another embodiment of a polyaxial screwdriver, the outer sleeve of the polyaxial screwdriver has a split end that securely engages the coupling element.
ROD COUPLING ASSEMBLIES FOR BONE STABILIZATION CONSTRUCTS
Bone implants and stabilizing rod coupling assemblies to secure a stabilizing rod relative to the bone implant. Bone implants may include a radially recessed collet receiving region that includes a proximal end with an undercut ledge configuration that is sized and configured to interface with and couple to a collet of a tulip assembly.
Quick lock clamp constructs and associated methods
Disclosed implants may include a first implant receiver and a second implant receiver each having an upper portion and a lower portion connected together by an arm portion, for example. In various embodiments, the upper and lower portions may define a longitudinal passageway extending through the upper and lower portions in a longitudinal direction of each implant receiver, and the arm portions may each define a rod passageway extending in a lateral direction, for example. In various embodiments, each receiver may include a crown having an outside thread pattern threadably engaged within the longitudinal passageway and for mating with a corresponding nut having a similar interior thread pattern. In various embodiments, a rod may extend in the lateral direction through the rod passageways In various embodiments, in a non-tightened position, the rod may freely move and in a tightened position, the arms constrain the rod from moving.
DUAL LOCKING POLYAXIAL SCREW HEAD
Systems, methods, and devices for securing a spinal rod are provided. A clamp assembly may include a tulip comprising a first opening and a second opening, wherein an inner surface of the first opening comprises threads; a saddle movably disposed within the tulip between the first and second openings, the saddle comprising a first end and a second end, the first end comprising a portion configured to receive a spinal rod, the second end comprising a cavity configured to receive a pedicle screw, the saddle comprising slots configured to receive a rotating tool; and a threaded locking cap disposed in the first opening.
MEDICAL IMPLANT THREADED PLUG HAVING A LOWER CENTRALIZED OPENING AND ROD ENGAGING PROTRUSION
A receiver assembly for securing an elongate rod to a bone anchor including a receiver and a threaded plug. The receiver including an upper portion defining a channel to receive the elongate rod, an interior surface having helically wound receiver thread, and an exterior surface having first and second horizontal curvate extending instrument engaging grooves. The threaded plug including a longitudinal axis, a lower surface having a protrusion, and an external side surface having a continuous helically wound closure thread to rotatably mate with the helically wound receiver thread. The continuous helically wound closure thread including a lower leading surface and an upper trailing surface, both extending perpendicular to the longitudinal axis, and a cylindrical outer crest surface extending parallel to the longitudinal axis. When the protrusion on the threaded plug engages the elongate rod, the threaded plug does not extend overtop a top surface of the receiver.
Bone anchor
An anchor assembly can be couplable to a bone and can include an anchor and a housing. The anchor can include a shank securable to bone and a head coupled to a proximal portion of the shank.
Surgical implant and methods of additive manufacturing
A method of manufacturing a surgical implant includes simultaneously forming a first component and a second component of the surgical implant. Formation of the first and second components includes depositing a first quantity of material to a building platform and fusing the first quantity of material to form a first layer of the first and second components. The method of manufacturing also includes depositing a second quantity of material over the first layer of the first and second components and fusing the second quantity of material to form a second layer of the first and second components. The surgical implant is fully assembled upon the completion of the formation of the first and second components.
