Embodiment Construction

[0021] It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other if there is no conflict. Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0022] According to one aspect of the present invention, there is provided an artificial vertebral body, such as Figure 1 to 4 As shown, the artificial vertebral body includes an upper connecting body 20, a lower connecting body 30, and a support portion 10. The support portion 10 connects the upper connecting body 20 and the lower connecting body 30. The support portion 10 includes a body 11 and an adjusting portion, the adjusting portion and the body The length of the supporting portion 10 can be adjusted by the adjustable connection of 11, and the main body 11 and the adjusting portion are connected to the upper connecting body 20 and the lower connecting body 30 respectively.

Abstract

The invention provides an artificial vertebra. The artificial vertebra comprises an upper connector, a lower connector and a supporting portion. The supporting portion is connected with the upper connector and the lower connector and comprises a body and an adjustment portion, adjustability in connection between the adjustment portion and the body enables length adjustability of the supporting portion, and the body and the adjustment portion are connected with the upper connector and the lower connector respectively. The upper connector and the lower connector of the artificial vertebra are used for being connected with two vertically adjacent vertebrae in a human skeleton, and due to length adjustability of the supporting portion, the artificial vertebra can adapt to different users to highly fit original vertebrae. In addition, since the distance between the upper connector and the lower connector is adjustable, the artificial vertebra can be connected with vertebrae of a human body more accurately, connection failure caused by stress concentration at a fixed position is avoided, and reliability and fitting degree in connection of the artificial vertebra and the human body can be improved.

Description

Technical field [0001] The invention relates to the technical field of artificial prostheses, in particular to an artificial vertebral body. Background technique [0002] Vertebral tumors, severely comminuted fractures, and certain infectious diseases such as tuberculosis often cause damage to the vertebral body, and may cause spinal cord and nerve damage or collapse of vertebral segments and angular deformity of the spine. People with neurological dysfunction or angulation deformity often require vertebral resection. [0003] The emergence of artificial vertebral bodies provides a more reliable treatment method for patients with spinal tumors, spinal tuberculosis and trauma. The current artificial vertebral body substitutes can be roughly divided into filling types, such as bone cement, supporting types, such as titanium mesh, and supporting fixed types. Due to the different design, its biomechanical stability is also different. Among them, the support type (titanium mesh) is t...
