The present invention relates to stable fixation of spine segments, allowing for fusion in, e.g., skeletally mature patients. More particularly, the invention relates to a bone fixation device that can be affixed to vertebrae of a spine to provide reduction (or enlargement) capabilities and allow for fixation in the treatment of various conditions, including, e.g., spondyloslisthesis, degenerative disc disease, fracture, dislocation, spinal tumor, failed previous fusion, and the like, in the spine. The invention also relates to a method for delivering and implanting the bone fixation device.

The invention relates to a movable three-dimensional rocker arc-shaped guide spinal puncture assistor, which comprises a ground movable support part, a three-dimensional rocker regulating part and an arc-shaped angle guide puncture part, wherein bottom feet of the ground movable support part are rolling wheels with brakes; a vertical rod which is sleeved by a round tube and is used for maintaining the integral balance is arranged above the ground movable support part; the three-dimensional rocker regulating part is of a three-dimensional regulating structure consisting of three rockers with screw threads and three extension rods, and also comprises a horizontal calibrator and a horizontal locking spanner; the arc-shaped angle guide puncture part comprises a 1 / 4 circular-arc rail with an angle, a rocker, two infrared fixed point instruments, a guide rod and a needle guide device; the rocker can realize 360-degree vertical rotation through regulating the circular-arc rail; the guide rail slides along the circular-arc rail; and the needle guide device can be dismounted for disinfection. The movable three-dimensional rocker arc-shaped guide spinal puncture assistor has the advantages that the puncture accuracy is high; the perspective time is short; the number of perspective times is small; the quantity of X-ray radiation received by medical care personnel and patients is low; the needle guide device can be disinfected and repeatedly used; and high molecular materials are radiotransparent, and the like. Therefore the movable three-dimensional rocker arc-shaped guide spinal puncture assistor can be widely applied to spinal surgeries such as intervertebral aperture mirror positioning puncture, epidural anesthesia, spinal tumor biopsy and spinal abscess puncture drainage.

The invention relates to a spinal digital surgery device based on micro-gap positioning, which includes a bearing platform, a controller is arranged on the bearing platform, an X-axis guide rail is arranged on the bearing platform, and a moving assembly is slidably connected to the X-axis guide rail. Yes: The mobile component is provided with a Y-axis guide rail, a column is slidably connected to the Y-axis guide rail, a Z-axis guide rail is distributed on the column, a beam is slidably connected to the Z-axis guide rail, a universal interface is provided on the beam, and a universal interface is connected to a The navigation robot arm and the decompression combination robot arm are connected with a locator on the navigation robot arm. In this way, it can assist the implementation of spinal surgery, especially to help medical staff perform spinal fractures, spinal tumors, scoliosis, intervertebral disc herniation, spinal stenosis, spondylolisthesis and other spinal surgery operations. The overall application range is wide, the positioning accuracy is high, the operation is simple, safe and reliable.

The invention discloses a multi-needle guide system for spinal radio-frequency ablation puncture. The system comprises puncture needles and a guide; each puncture needle comprises a puncture portion at the front end of a needle head and a guide portion at the rear portion of the needle head; each puncture needle is at least internally provided with parallel passages, and each puncture needle is further provided with a plurality of oblique passages; the oblique passages penetrate between the puncture portion and the guide portion of the corresponding puncture needle and are different from the corresponding puncture needle in inclination angle, and the front end of each oblique passage is positioned on the same side of the corresponding puncture portion; the guide comprises a connection portion and a guide arm. By the aid of the multi-needle guide system, imbedding directions of the radio-frequency electrode needles can be guided accurately, precision multi-needle guided puncture for ablation of spinal tumors is realized, the radio-frequency electrode needles are enabled to reach preset spinal portions according to designed angles and to be uniformly distributed at different spinal positions to completely cover a whole spinal structure, and consequently treatment effectiveness is greatly improved.

The invention relates to a method for making a thoracolumbar vertebra deformity posterior individualized osteotomy navigation template. The method is characterized by comprising the following steps: reconstructing a three-dimensional model of whole spine and pelvis based on a medical image; performing a simulate operation on the three-dimensional model; simulating osteotomy to recover normal physiological curvature of the spine; and making an osteotomy template according to the osteotomy position and size of the simulate operation; and printing the osteotomy template by 3D printing. The osteotomy template is individualized; in the operation, the subjectivity in selecting the osteotomy position and size and the repeated operation perspective and the like are avoided; the method is suitable for the kyphosis orthopaedics of old thoracolumbar vertebra fracture, orthopaedics of spinal tumor, osteotomy orthopaedics of ankylosing spondylitis and the like; and moreover, the operation is easy, the requirements on doctors are relatively low, the operation risk is lowered, the operation efficiency is increased, and the operation cost is reduced.

The invention relates to a combined artificial vertebral body and belongs to the technical field of internal fixation of implantation materials of vertebral column surgery. The combined artificial vertebral body is especially used for treating the diseases, such as spinal tumor, tuberculosis and fracture, and for replacing the vertebral body and recovering a normal physiological function of the vertebral column of human body. The combined artificial vertebral body comprises convex cover plates, concave cover plates, fixing bolts, an inner supporting block, an outer supporting block and a spring; the inner supporting block is mounted in an inner hole of the outer supporting block; the spring is inserted into the inner hole of the inner supporting block; the concave cover plates are mounted at the two ends of the outer supporting block through the fixing bolts; the two convex cover plates are respectively assembled on concave spherical surfaces of the two concave cover plates through convex spheres, thereby forming the combined artificial vertebral body; hemispheric convex spheres are arranged on one surfaces of the convex cover plates; sharp cylinders which are uniformly distributed and thin plates which are vertical to the convex cover plates and are provided with tooth-shaped grooves are arranged on the other surfaces of the convex cover plates; the concave spherical surfaces are respectively arranged on one surfaces of the concave cover plates; the concave spherical surfaces are arranged for accommodating the convex spheres of the convex cover plates; and a plurality of cylindrical footstep holes are arranged in one sides of the concave spherical surfaces of the concave cover plates.
