Abstract: Proposed is a patient-specific spinal rod using 3D printing and a pedicle fixation device including the same. The rod is characterized in that information of a damaged spine is obtained through X-rays or computed tomography (CT) scans before surgery, an image is created by considering the setting of a coupling part of the rod that is combined with a pedicle screw inserted and fixed in a vertebral body to allow two or more vertebral bodies to fuse and a bending shape according to curve of a spine, and a metal material is melted and output by 3D printing to have an appearance corresponding to the created image. The rod includes a rod-shaped coupling portion coupled with the pedicle screw, and a support portion configured to extend in a longitudinal direction of the coupling portion to serve as a support for holding the spine.

Abstract: Disclosed is a patient-specific mandibular implant inserted into a mandibular defect region and a method of manufacturing the same, and more particularly, to a patient-specific mandibular implant inserted into a mandibular defect region, which can be easily and rapidly manufactured using personalized three-dimensional (3D) printing technology for a defect region, can provide an effect of preparing a later step for restoring a tooth in advance, and can be easily manufactured tooth restoration data based on the Korean standard database (DB), and a method of manufacturing the same.

Abstract: A patient-specific artificial temporomandibular joint is proposed. The patient-specific artificial temporomandibular joint includes: a temporal bone coupling part including a fixing body that is fixed to the temporal bone of a patient and a head receiver that is detachably coupled to the fixing body and provides a close-contact curved surface being open downward; and a mandible coupling part including a coupling body that is fixed to the mandible of a patient and a head that has a spherical shape and is supported by the coupling body in contact with the close-contact curved surface of the head receiver. The patient-specific artificial temporomandibular joint is manufactured by 3-D printing on the basis of shape data of the temporal bone or the mandible of a patient, so a good implanting effect is provided and the patient quickly recovers. Further, worn parts can be partially replaced, thus there is a little burden of maintenance.

Abstract: Disclosed is a spinal cord protecting apparatus. The spinal cord protecting apparatus includes a body and a fixture. The body is formed in a porous plate shape to cover an exposed spinal cord. The fixture is configured to fix the body. Accordingly, the spinal cord exposed to the outside is safely protected, so that an additional disease is prevented.
