Embodiment Construction

[0033] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0034] figure 1 A schematic structural view of an embodiment of the artificial vertebral body fixation system according to the present invention is shown. Such as figure 1 As shown, the artificial vertebral body fixation system of this embodiment includes: an artificial vertebral body main body 10 , two longitudinal connecting rods 20 , transverse connecting nails 30 and connecting parts 40 . Wherein, the artificial vertebra body main body 10 is arranged between adjacent human physiological vertebral bodies 1 , and two longitudinal connecting rods 20 are respectively arranged on both sides of the spinous processes of the human physiological vertebral bodies 1 . The artificial vertebral body ...

Abstract

The invention provides an artificial vertebral body fixing system, which comprises an artificial vertebral body main body arranged between adjacent human physiology vertebral bodies; two longitudinal connecting rods respectively arranged on two sides of spines of the human physiology vertebral bodies; cross connection nails connected between the artificial vertebral body main body and the longitudinal connecting rods; a connecting part connected onto the artificial vertebral body main body, and is provided with self-tapping through holes or threaded holes. When the connecting part is provided with the self-tapping through holes, the cross connection nails are screwed in the self-tapping through holes so as to be self-taped to form thread structures; when the connecting part is provided with the threaded holes, the cross connection nails are matched with the threaded holes. The technical scheme provided by the invention effectively solves the problem of poor artificial vertebral body stability in the prior art.

Description

technical field [0001] The invention relates to the field of orthopedic implants, in particular to an artificial vertebral body fixation system. Background technique [0002] In the treatment of human spine diseases, vertebral body destruction is often caused by spinal tumors, tuberculosis and severe fractures, which may lead to spinal cord nerve damage and have to perform vertebral body resection. The spine after vertebral body resection needs to rebuild its stability, and the emergence of artificial vertebral body replacement provides an ideal method for the treatment of such diseases. Since the first report of vertebral body tumor resection and prosthetic replacement in the late 1960s, artificial vertebral bodies have been widely used clinically as a kind of effective vertebral body substitutes. [0003] However, in clinical application and a series of biomechanical tests, it has been shown that the traditional artificial vertebra has some problems to be solved in some a...
