Abstract: A surgical implant device, comprising: a body portion; and one or more surfaces comprising a plurality of protruding structures; wherein the body portion and the one or more surfaces comprising the plurality of protruding structures are integrally formed. The one or more surfaces comprising the plurality of protruding structures are formed by an additive manufacturing process. The plurality of protruding structures comprise a plurality of needles. Optionally, the surgical implant device comprises one of an anterior lumbar interbody fusion cage, a posterior lumbar interbody fusion cage, a transforaminal lumbar interbody fusion cage, an oblique lumbar interbody fusion cage, a cervical cage, and a bone screw.

Abstract: A surgical implant device, comprising: a body portion defining a plurality of ports; a plurality of bone screws disposed partially through the plurality of ports defined by the body portion; a locking plate disposed over a head portion of at least one of the plurality of bone screws and engaging a plurality of recesses manufactured into a side of the body portion; and a screw operable for compressing the locking plate against the side of the body portion. Optionally, the surgical implant device further comprising: one or more surfaces comprising a plurality of protruding structures; wherein the body portion and the one or more surfaces comprising the plurality of protruding structures are integrally formed. The one or more surfaces comprising the plurality of protruding structures are formed by an additive manufacturing process.

Abstract: A surgical plate device that incorporates a screw locking mechanism in each screw hole by which the surgical plate device is affixed to a bony segment. The screw locking mechanism includes a tab structure emanating from an interior portion (or either surface) of the surgical plate that is biased into a portion of the corresponding screw hole. When a screw is inserted into the screw hole, the head of the screw temporarily biases the tab structure out of the screw hole, until the head of the screw passes below the plane of the tab structure, at which point the tab structure rebounds into the previously occupied portion of the screw hole, thereby covering a portion of the head of the screw and preventing it from “backing out.

Abstract: A driver device (hexalobe or otherwise) that includes a handle portion, an elongate shaft portion, and an end portion that includes a screw engagement portion and a split manufactured offset from the central axis of the end portion and/or the screw engagement portion, forming two asymmetric halves of the end portion and/or screw engagement portion. This screw engagement portion is slightly oversized relative to the corresponding tool engagement recess of the locking cap, set screw, or bone screw. Thus, when the screw engagement portion is pressed into the corresponding tool engagement recess of the locking cap, set screw, or bone screw, the split manufactured offset from the central axis of the end portion and/or the screw engagement portion allows the screw engagement portion to compress slightly, creating a friction fit between the screw engagement portion and the corresponding tool engagement recess of the locking cap, set screw, or bone screw.

Abstract: A modular surgical tool that is used to insert instruments into the intervertebral disc space of a patient to measure the height of the intervertebral disc space, to prepare the intervertebral disc space for an implant, and to insert the implant into the intervertebral disc space using a plurality of interchangeable tool ends. Advantageously, this modular surgical tool permits multiple insertion angles.
