This invention discloses a spinal osteotomy path planning device, method, and system, belonging to the field of medical device technology. The spinal osteotomy planning device is capable of planning the osteotomy path for spinal osteotomy surgery, specifically including: an identification module, an acquisition module, and a determination module. The identification module is used to identify feature points of at least two vertebrae based on a spinal scan image of the target object. The acquisition module is used to obtain the size of the lesion based on a pathological image of the target object. The determination module is used to determine the osteotomy area on the vertebrae to be osteotomized based on the feature points and the size of the lesion.

A corpectomy implant device having a solid portion, structural volume and porous end plates configured is disclosed. In some embodiments, the corpectomy device comprises a stochastic lattice structure in the structural volume of the device to reduce stiffness and improve radiolucency. In some embodiments, the porous endplates comprise a lattice configured to provide porosity for bone ingrowth. In some embodiments, endplates are configured to facilitate insertion of the implant between the adjacent vertebrae and to provide anchoring of the corpectomy device to and prevent migration of the device implant in an installed state.

This utility model discloses a depth-limiting sheath assembly for endoscopic-assisted anterior cervical surgery, comprising an outer sheath and an inner sheath, the inner sheath being inside the outer sheath. The outer sheath has a depth-limiting locking block at its tip, which, during operation, can be locked in front of the cervical vertebrae to limit the depth of the sheath and endoscope. One end of the outer sheath is fixedly connected to a receiving cavity, and a pressure block is disposed within the receiving cavity. One end of the pressure block is connected to the receiving cavity via a first spring, and the pressure block is slidably connected to the receiving cavity. This utility model provides a depth-limiting sheath assembly for endoscopic-assisted anterior cervical surgery, which, through the relative movement of the spring-loaded pressure block between the endoscope and the sheath, limits the depth and allows for relative adjustment of the endoscope's position, facilitating observation of the intervertebral discs.

The utility model discloses a device for rotating an orthopedic track in scoliosis deformity surgery, which comprises two forceps arms hinged with each other, the two ends of each forceps arm are respectively a clamping end and a holding end, and the hinge point between the two forceps arms is positioned between the clamping end and the holding end of each forceps arm. The clamping end of each clamp arm is provided with two clamping arms capable of moving close to or away from each other. The utility model aims to provide the device for rotating the orthopedic track in the scoliosis deformity operation, and the device can enable two adjacent vertebral bodies with overlarge intervertebral space to move close to each other, so that the space between the two vertebral bodies is reduced to meet the requirement.

A motion-preserving spinal implant is presented for placement within the intervertebral space for the total replacement of a degenerated spinal disc. The motion-preserving spinal implant has a pair of endplates sandwiched around an inner and an outer core, with the inner core positioned concentrically within the outer core. The outer core encapsulates the inner core and provides a proper seal while maintaining flexibility and elasticity to advantageously support physiological movements. The inner core is constructed of an elastomeric material and acts as a solid diaphragm to resist and withstand localized compression and other forces. The endplates provide anchorage and fusion with the adjacent vertebrae and maintain the inner and outer cores in place.The motion-preserving spinal implant restores normal height and natural function to the degenerated spinal disc and preserves natural spinal movement.

The invention discloses a device for rat caudal vertebra intervertebral disc degeneration. The device comprises a fixing unit and a loading unit. The fixing unit comprises two metal rings which are respectively fixed on adjacent vertebral bodies on the upper side and the lower side of a target intervertebral disc; at least two nails used for being implanted into a vertebral body are arranged on the circumference of the inner side of each metal ring; a plurality of hooks are arranged on the circumference of the outer side of each metal ring; the loading unit comprises at least two hook springs, and the two ends of the hook springs are detachably connected to the hooks at the specific positions of the upper metal ring and the lower metal ring. Through the combination of the angle of the hook and the rigidity of the spring, complex multi-dimensional mechanical loads borne by the spine in the physiological or pathological state can be simulated, the loads are not only pressure in the single direction and are closer to the actual stress condition of the intervertebral disc of the human body, the angle position of the hook is fixed, and the rigidity of the spring is known; this allows the applied load to be accurately calculated and repeated.

Image-guided navigation for spinal cord treatments and therapies are described. The image-guided navigation is augmented with anatomical measurement data related to spinal cord and vertebral anatomy. From these data and medical image data, an augmented model of spinal cord anatomy is generated and / or navigation data can be generated for localizing spinal cord structures, such as by mapping the anatomical measurement data to the medical image data. The augmented model data and / or navigation data can be used for surgical navigation, stimulation parameter setting, electrode configuration selection, pre-surgical planning, surgical visualization, and so on.

A method for installing an expandable interbody (intervertebral) spine implant with a two-piece medical instrument via an endoscope, the two-piece medical instrument having a handle assembly and a shaft assembly configured for extension through the endoscope, the shaft assembly holding an expandable interbody spine implant when the shaft assembly is fully received by a head of the handle assembly, and releasing the spine implant upon retraction of the shaft assembly from the head of the handle assembly. The shaft assembly has a rod with a longitudinal bore and a sleeve situated on the rod that axially moves relative to the rod in response to the reception into and retraction from the handle assembly head, with the sleeve controlling capture and release of the implant by the rod. The distal end of the rod has a clamp formed by jaws that flex to capture and release the implant.
