The present invention relates to an interspinous integration type implant. Provided is an interspinous integration type implant which is an implant inserted between an upper spinous process and a lower spinous process and comprises: a spacer to which one end of an upper plate and one end of a lower plate are connected so as to be formed in a “” shape or “U” shape, and which is inserted between spinous processes in order to provide elasticity; an upper spinous process coupling means for tightly coupling the upper plate to the upper spinous process; and a lower spinous process coupling means for tightly coupling the lower plate to the lower spinous process, wherein the upper plate comprises at least one osseointegration hole formed to penetrate the top surface and the bottom surface of the upper plate so as to be moved by being integrated with the upper spinous process, and the lower plate comprises at least one osseointegration hole formed to penetrate the top surface and the bottom surface of the lower plate so as to be moved by being integrated with the lower spinous process. The interspinous integration type implant according to the present invention provides elasticity to the upper spinous process and the lower spinous process, thereby maintaining a space between the upper and lower spinous processes. Also, the interspinous integration type implant moves by being integrated with the upper and lower spinous processes through the osseointegration holes formed at the upper plate and the lower plate, and thus does not damage the spinous processes and has an effect of preventing a separation phenomenon from between the spinous processes. Also, the interspinous integration type implant has an effect of enabling minimally invasive surgery since blades can be rotated and tightened using an instrument after inserting the interspinous integration type implant from the side surface of spinous processes. Furthermore, after inserting the interspinous integration type implant between adjacent spinous processes and tightening the blades at both side surfaces of the spinous processes, a plurality of spikes provided in the blades are tightly embedded on the both side surfaces of the spinous processes, and thus there is an effect that an upper blade and a lower blade are stably coupled to the upper and lower spinous processes. In addition, since the interspinous integration type implant can be inserted between the spinous processes in a state where the upper blade an

The present invention provides an intervertebral implant for implantation in a treated area of an intervertebral space between vertebral bodies of a spine. The implant includes a spacer portion having an inferior and superior surface, wherein the inferior and superior surfaces each have a contact area capable of engaging with anatomy in the treated area, and the inferior and superior surfaces define a through-hole extending through the spacer body. The present invention further provides holes extending from a side portion to the inferior and superior surfaces of the spacer portion and a plate portion rigidly coupled to the spacer portion, wherein the plate portion contains holes for receiving screws. A fastener back out prevention mechanism adapted on the plate to prevent the back out of the fasteners from the holes and to secure the spacer to the plate of the intervertebral implant.

An expandable interbody spacer for the spine is provided. The interbody spacer includes a housing, a top endplate and a bottom endplate. An actuator is located inside the housing between the top and bottom endplates. A locking screw is configured to drive the actuator and move the endplates between collapsed and expanded configurations. Variations of the expandable spacer are provided in which the endplates move bilaterally outwardly into uniform and parallel expansion along the latitudinal axis, the endplates angulate about a pivot point along a longitudinal axis such that the distal end of the spacer increases in height relative to the proximal end, and the endplates angulate about a pivot along a lateral axis such that the height along one lateral side of the spacer increases in height relative to the other lateral side.

Disclosed are a fusion cage for a spinal surgery and a clamping device thereof. The fusion cage comprises a fusion cage body (1) and a triangular screw plate (2). A limiting groove (12) fit with the clamping device is provided at a rear end surface of the fusion cage body (1), the fusion cage body (1) is hinged with the screw plate (2), and each of three corners of the screw plate (2) is provided with a screw hole (23). The clamping device comprises two clamping rods (4) which are fit with each other, and a front end of each clamping rod (4) is provided with a clamping head (41), wherein each of face-to-face sides of the clamping heads (41) is provided with a limiting protrusion (42), a front end of each clamping head (41) is capable of being inserted into the limiting groove (12) of the fusion cage body (1), and the limiting protrusion (42) is capable of being clamped at a front side surface of the screw plate (2). The fusion cage and the clamping device can easily fit with each other and are convenient to use, so as to enable the surgical operation to be more convenient, accurate and safe.

An expandable fusion device may include a first endplate and a second endplate. The expandable fusion device may also include first and second ramps configured to mate with both the first and second endplates. The first ramp may include a mating feature having a first angle relative to a vertical axis, and the second ramp may include a mating feature having a second angle relative to the vertical axis such that the first angle is different from the second angle. In particular, the first and second ramps may be configured to provide for symmetrical expansion of the first and second endplates.

The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In one embodiment, the fusion device includes a body portion, a first endplate, and a second endplate, the first and second endplates capable of being moved in a direction away from the body portion into an expanded configuration or capable of being moved towards the body portion into an unexpanded configuration. The fusion device is capable of being deployed and installed in both configurations.

An implant device having a non-conductive base structure with at least two exposed or exterior surfaces wherein at least one of the exposed or exterior surfaces has attained electrical conductivity on at least portions of the surface by an energy exposure wherein portions of the exposed or exterior surfaces are transformed by the energy exposure to attain the electrical conductivity.

An implant suitable for being anchored with the aid of mechanical vibration in an opening provided in bone tissue. The implant is compressible in the direction of a compression axis under local enlargement of a distance between a peripheral implant surface and the compression axis. The implant includes a coupling-in face which serves for coupling a compressing force and the mechanical vibrations into the implant, which coupling-in face is not parallel to the compression axis. The implant also includes a thermoplastic material which, in areas of the local distance enlargement, forms at least a part of the peripheral surface of the implant.
