A spinal implant device for placement between vertebral bodies includes a housing, at least one screw member in the housing, and at least one drive shaft operably engageable with the screw member. The housing includes a first shell member and a second shell member. At least the first shell member has step tracking comprising a plurality of individual riser members for receiving the at least one screw member. The height of the plurality of individual riser members may change along the step tracking. The drive shaft may be operable to rotate the at least one screw member, causing the at least one screw member to move on the plurality of individual riser members. The at least one screw member comprises an external helical thread having a thickness configured to fit in the gaps between adjacent individual riser members, and is engageable with the first and second shell members, whereby the first and second shell members move relative to each other in response to the rotation of the at least one screw member to effect an expansion of the housing or a contraction of the housing from the expansion by reversing the rotation of the at least one screw member.

The present disclosure provides adjustable spinal devices, instruments for implanting the spinal devices, methods for adjusting the height and lordosis angles of the spinal devices and methods for implanting such devices. An adjustable spinal fusion device includes an upper plate component having an outer surface for placement against an endplate of a vertebral body and a lower plate component having an outer surface for placement against an endplate of a vertebral body. The device further includes a first translation member configured to move longitudinally relative to the upper and lower plates to adjust a distance between the upper and lower plates and a second translation member configured to move longitudinally relative to the upper and lower plates to adjust an angle between the upper and lower plates.

The present disclosure provides adjustable spinal devices, instruments for deploying the spinal devices, methods for adjusting the height and / or lordosis angles of the spinal devices, and methods for implanting such devices. An adjustable spinal fusion device includes an upper plate having an outer surface for placement against a first vertebral body and a lower plate having an outer surface for placement against a second vertebral body. The device further includes a translation member configured to move longitudinally relative to the upper and lower plates to adjust an angle between the upper and lower plates and a locking member coupled to the translation member. The locking member is movable between an unlocked position, wherein the translation member is capable of moving in the longitudinal direction, and a locked position, wherein the translation member is inhibited from moving in the longitudinal direction.

According to the user cervical vertebra and lumbar vertebra health management system and method, RGB-D image (vision) and Bluetooth assisted positioning (hardware) are combined, and the 3D coordinate precision of spine key points is improved; quantitative calculation of spine physiological parameters (such as a Cobb angle and a lobular / lobular angle) is introduced, and the orthopedic medical standard is met; a standard detection action is displayed through AR animation, the posture of a user is dynamically corrected, and the data acquisition quality is ensured; algorithms such as dynamic time warping (DTW) are adopted, the matching degree of user actions and standard actions is evaluated, and closed-loop optimization of'detection-guiding-re-detection 'is achieved. Visual report display can be carried out on cervical vertebra and lumbar vertebra lateral bending of the user, a doctor can check historical data of the user through a background system to assist in making a treatment scheme, and intelligent management is achieved.

The invention discloses a minimally invasive ultrasonic guided percutaneous rabbit intervertebral disc degeneration modeling mode, and relates to the technical field of ultrasonic modeling, and the method comprises the following steps: fixing an experimental rabbit on an operation table in a prostrate manner in an anesthetic state, and raising the abdomen to maintain lumbar lordosis; an ultrasonic probe is used for scanning along the longitudinal axis of the spine, and the L5 transverse process is recognized upwards from the highest point of the crista iliaca; positioning an L5 / 6 intervertebral disc gap in the cross section ultrasonic image by taking the identified L5 transverse process as an anatomical reference; a stable high-echo target spot formed by fascia is confirmed in the intersection area of the L5 transverse process head side and the superior articular process ventral side; marking a puncture needle insertion position on the skin surface according to the high-echo target spot; percutaneous puncture is conducted under ultrasonic real-time guidance along the marked position, the needle tip slides into the L5 / 6 intervertebral disc along the superior zygopophysis bone surface, and it is confirmed that the needle tip is located in the nucleus pulposus through viscous resistance and the unlocking hand feeling; the needle tip is controlled to stay in the intervertebral disc for 10 seconds, the puncture depth is kept at 5 mm, and mechanical disturbance is completed to induce the intervertebral disc to retreat.

A spinal implant for placement between vertebral bodies includes a first member for engaging one of the vertebral bodies, a second member for engaging an opposing one of the vertebral bodies, and at least one extendable support element for inducing movement of the entire first member away from the second member. The first member is connected to the second member such that the first member moves away from the second member by a larger distance at a first end of the implant than at a second end of the implant. A connecting member may connect the first and second members together at the second end of the implant. The connecting member may include one or more rotatable linkages, or the connecting member may be an extension of one of the first and second members slidably received within a track defined within the other of the first and second members.
