The invention discloses an intervertebral disc implant manufacturing method and an intervertebral disc implant. The manufacturing method of the intervertebral disc implant comprises the following steps that the upper bone plate and the lower bone plate are manufactured in an additive mode; an upper fiber ring and a lower fiber ring are manufactured through additive manufacturing, the upper fiber ring is connected to the lower side of the upper bone plate, and the lower fiber ring is connected to the upper side of the lower bone plate; the polymer nucleus pulposus is manufactured in the lower fiber ring or the upper fiber ring in an additive mode; and the lower end face of the upper fiber ring and the upper end face of the lower fiber ring are bonded. The intervertebral disc implant obtained through the manufacturing method of the intervertebral disc implant is more suitable for a human body to use, and the problem that vertebrae need to be cut off in a large scale in a traditional implantation operation can be solved.

The application discloses an experimental animal spinal column specimen dissection instrument and a dissection method. The dissection instrument comprises a fixing device, a scanning device, a cutting device and a control device. The fixing device is used for fixing the experimental animal spinal column specimen. The scanning device is used for scanning the fixed experimental animal spinal column specimen and transmitting a scanning image to the control device. The cutting device cuts the experimental animal spinal column specimen according to a cutting instruction of the control device or manually. The dissection instrument of the application integrates the fixing and cutting functions, significantly improves the efficiency and precision of the experimental animal spinal column specimen dissection, reduces the error and labor intensity of manual operation, makes the dissection process more consistent and reliable, and has high flexibility and adaptability, so that the dissection instrument can meet the dissection requirements of spinal column specimens with different sizes and curved shapes, and provide more reliable dissection samples and experimental data support for the fields of spinal column disease research, spinal cord injury repair and artificial vertebral body / intervertebral disc implant research and development.

Systems, devices, and methods for maintaining motion in an intervertebral disc. A modular disc implant segment may be constructed from a relatively solid material configured to exhibit certain characteristics of a compressible solid, such as an elastomer. The material may be configured to include one or more structural voids, such as a leaf spring design, to facilitate the compression capability of the modular disc implant segments such that an entire disc composed of multiple modular disc implant segments can compress as the implant recipient moves.

A spinal disc implant including a body defined by a plurality of interwoven or braided nitinol strands. The body includes a first end and a second end. The nitinol strands come together at the first end and are secured with a first fitting. The nitinol strands also come together at the second end and are secured with a second fitting. The second fitting can include a snare hook. The braided nitinol skeleton is internally assembled within the intervertebral disc. The implant is filled with liquid, gel or silicone when utilized as a motion preserving nucleus pulpous implant. The implant is filled with bone graft material when utilized as an inter-body fusion implant. An instrument and technique that provides a minimally invasive “needle based” solution to address degenerative disc disease with enhanced structural integrity of the spine compared to conventional surgical devices and techniques.

Systems, apparatuses and methods for preserving motion in an intervertebral disc. Modular disc implant segments can be constructed from a relatively rigid material with compressive spring lobes to act similar to an elastomer. The lobes may be configured to have a C-shaped outer wall and one or more spring arms, such as a leaf springs, to facilitate the modular disc implant segment's ability to compress, thereby enabling an entire intervertebral disc constructed from multiple modular disc implant segments to compress with the implant recipient's movement. The implant segments are sized to be inserted serially into a space defined by the annular fibrosus after removal of the nucleus pulposus with connections being made between adjacent segments in the space during the insertion process.

To provide patient-specific artificial discs, implants and associated systems and methods.SOLUTION: Systems and methods for designing patient-specific medical devices are described herein. In some embodiments, a method includes obtaining patient data that includes image data and kinematic data of a patient's spine. A virtual model of the patient's spine is generated and can be manipulated until a target anatomical configuration is achieved. A patient-specific implant can then be designed based at least in part on the target anatomical configuration and the kinematics such that, when the patient-specific implant is implanted in the patient, the patient-specific implant provides the target anatomical correction while maintaining or improving the kinematics of the patient's spine.SELECTED DRAWING: Figure 1C
