Problems solved by technology

[0002] After a vertebra in the spine is damaged, it is necessary to use an artificial vertebra to replace the damaged vertebra. Traditionally, when the artificial vertebra is fixed on the damaged vertebra, the artificial vertebra is fixed on the adjacent vertebra with pins. , thereby limiting the activity space of the artificial vertebral body, thus making the spinal column in the damaged position stiff and uncomfortable, and because the traditional artificial vertebral body mesh structure is installed on the damaged vertebrae, its mesh structure damage to adjacent vertebrae

Abstract

The invention discloses a (3D printing) artificial vertebral body system, which relates to the technical field of medical appliances. It includes an adjusting screw groove in the middle of the bottom end of the bionic hemivertebra; a thread groove in the middle of the top of the bionic hemivertebra; a fixing screw connected to the inner thread of the thread groove; vertical anti-slip lines are evenly opened on the outer surface of the fixing screw along the circumferential direction There is an adapter groove in the middle of the top of the bionic half cone; the adapter groove is connected with the thread groove; there is an operation window at the upper right end of the bionic half cone; the operation window is connected with the adapter groove; A honeycomb pouring layer; a silica gel layer is poured in the pouring layer; a connecting hole is opened in the middle part of the top of the silica gel layer; the connecting hole is connected with the matching groove. The beneficial effects of the invention are: the implantation of the artificial vertebral body is more convenient, the silica gel layer protects the vertebral body, reduces abrasion, has physiological curvature, does not cause damage to the vertebral body, and is more comfortable and safe for patients to use.

Description

technical field [0001] The invention relates to the technical field of medical appliances. Background technique [0002] After a vertebra in the spine is damaged, it is necessary to use an artificial vertebra to replace the damaged vertebra. Traditionally, when the artificial vertebra is fixed on the damaged vertebra, the artificial vertebra is fixed on the adjacent vertebra with pins. , thereby limiting the activity space of the artificial vertebral body, thus making the spinal column in the damaged position stiff and uncomfortable, and because the traditional artificial vertebral body mesh structure is installed on the damaged vertebrae, its mesh structure There is also damage to adjacent vertebrae. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a (3D printing) artificial vertebral body system in view of the above technical deficiencies. The implantation of the artificial vertebral body is more convenient. T...
