The first, second, third, and fourth interfaces are designed such that the first interface at the intubation instrument is connectable directly to the second interface at the display device and is alternatively connectable directly to the third interface at the cable, and such that the second interface at the display device is connectable directly to the first interface at the intubation instrument and is alternatively connectable directly to the fourth interface at the cable.

Abstract: An expandable, adjustable inter-body fusion device is presented. The inter-body fusion device can have a first plate, a second plate, and an insert positioned substantially therebetween the first plate and the second plate. The first plate, the second plate, and the insert define an interior cavity. Moving the insert longitudinally with respect to the first and second plates increases or decreases the distance of the first plate with respect to the second plate, effectively expanding the inter-body fusion device and increasing the volume of the interior cavity. The angle between the first plate and the second plate is selectively adjustable.

Abstract: A lateral retractor system for forming a surgical pathway to a patient's intervertebral disc space includes a single dilator and a retractable dual-tapered-blade assembly. The single dilator may feature a narrow rectangular body for insertion at an insertion orientation parallel to the fibers of the patient's psoas muscle and at an approximate 45-degree angle to the patient's spine. The retractable dual-tapered-blade assembly consists of only two blade subassemblies, each having a blade bordered by adjustable wings, along with built-in lighting and video capabilities. The dual-tapered-blade assembly may be passed over the single dilator at the insertion orientation and rotated approximately 45-50 degrees from the insertion orientation to a final rotated orientation parallel to the intervertebral disc space before the two blade subassemblies are retracted away from one another to create the surgical pathway. Other embodiments are also disclosed.

Abstract: A lateral spine implant has a lateral spine cage and an associated lateral spine plate with one or more folding vertebral attachment arms, each arm configured for attachment to vertebral bone. The ability of the one or more arms to fold allows the lateral spine plate to be inserted/implanted at a lower profile height than traditional lateral spine plates. The lateral spine plate is meant to be used at times of intended or unintended compromise of the anterior longitudinal ligament (ALL) to prevent interbody cage migration, but may be adapted for any lateral plating application. Once expanded, each attachment arm is configured to receive a bone screw for securing the attachment arm to a vertebra, the bone screw retained by rotating cam lock nuts of the attachment arm.

Abstract: An impaction tip can be used in installing an implant. The impaction tip can comprise a body, and a sliding member. The body can have a handle-facing surface and an implant-facing surface. The body can define a grooved portion. The handle-facing surface can define an opening sized to receive a portion of an impaction handle. The sliding member can be located at least partially within the grooved portion. The sliding member can be slideable from an interior position to an exterior position. When the sliding member is in the exterior position a portion of the sliding member can contact the implant.

Abstract: A computer-assisted surgery system for obtaining a distance between at least two fixed points relative to a bone comprises a first accelerometer unit located at a first fixed location on the bone, and producing first acceleration data during a movement of the bone. A second accelerometer unit is located at a second fixed location on the bone, and simultaneously producing second acceleration data during the movement. A gyroscope unit is fixed to the bone and simultaneously producing angular rates of change of said movement. A processor unit obtains the acceleration data and the angular rates of change for calculating the distance between the first fixed position and the second fixed position on the bone using a distance value of a distance vector between the accelerometer units. An interface outputs the distance between the first fixed position and the second fixed position relative to the bone. A method for calculating a distance between at least two points on a bone is provided.

Abstract: A flexible arm for use in a medical procedure includes a plurality of bushings and a plurality of double-ball members engaged with one another to thereby provide flexibility to the flexible arm. The double-ball members include a concave bore having a convex interior surface. The flexible arm further includes a wire extending through the concave bore of the double-ball members. An exterior diameter of the wire closely approximates or matches an interior diameter of the concave bore at its smallest point such that the curved members are operable to guide the wire as the flexible arm is flexed. The wire may be adjusted to thereby manipulate the amount of engagement between the bushings and the double-ball members to thereby manipulate the flexibility of the flexible arm.
