Problems solved by technology

Before performing the vertebral body resection, firstly, the osteotomy and resection range should be established according to the patient’s spinal imaging data and surgical planning. At present, most of the artificial vertebral bodies are mass-customized and have a fixed height. The required height does not match, and the height of the prosthesis cannot be adjusted and changed according to the actual osteotomy height during the operation, and the lack of flexibility makes it difficult to install the prosthesis during the operation, which poses a major threat to the patient's life safety; and Personalized 3D printed prostheses are expensive to customize and difficult to promote
[0003] Patent document CN103156712A discloses an artificial vertebral body that can be used as an alternative structure for intervertebral body repair. It is made of hydroxyapatite or zirconia bioceramic composite material. There is a radial cross-shaped cavity on the peripheral surface of the body, but this design is based on preoperative planning and design, and still lacks the ability to adjust during operation, and still cannot avoid surgical risks

Embodiment Construction

[0054] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0055] According to a height-adjustable artificial vertebral body provided by the present invention, such as figure 1 As shown, it includes a fixed body 100, a telescopic body 200 and a connecting piece 300. The fixed body 100 includes a first accommodating space 110 and a first connecting end 120. The fixed body 100 is integrally connected with the first connecting end 120. The telescopic body 200 includes a first Two connecting ends 210, one end of the telescopic body 200 is movably connected with the...

Abstract

The invention provides an artificial vertebral body with adjustable height. The artificial vertebral body comprises a fixed body (100), a telescopic body (200) and a connecting piece (300). The fixedbody (100) comprises a first accommodating space (110) and a first connecting end (120). The fixed body (100) is integrally connected with the first connecting end (120). The telescopic body (200) comprises a second connecting end (210). One end of the telescopic body (200) is movably connected with the second connecting end (210), and the other end is mounted in the first accommodating space (110) in a matched manner and is connected with the fixed body (100) through the connecting piece (300). By inserting the telescopic body (200) into or pulling the telescopic body (200) out of the fixed body (100), the length of the artificial vertebral body is flexibly adjusted, and the problem that the heights of standardized prostheses are not matched due to individualized differences of vertebralbodies and tumor sizes of patients in the spinal tumor excision and reconstruction operation process is effectively solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a height-adjustable artificial vertebral body. Background technique [0002] As a kind of effective vertebral body substitutes, the artificial vertebral body has been widely used clinically, which has brought great convenience to the treatment of spinal tumors and other diseases. The artificial vertebral body can not only restore the physiological and anatomical structure of the spine, but also correct the posterior spine Convex deformity, reconstructed for spinal stability with very good results. Before performing the vertebral body resection, firstly, the osteotomy and resection range should be established according to the patient’s spinal imaging data and surgical planning. At present, most of the artificial vertebral bodies are mass-customized and have a fixed height. The required height does not match, and the height of the prosthesis cannot be adjusted and changed ...
