Abstract

The invention discloses a displacement spring and an artificial intervertebral disk with the displacement spring, in particular an artificial intervertebral disk which can buffer the axial pressure by using the displacement spring. The artificial intervertebral disk comprises the displacement spring, wherein the displacement spring comprises a substrate, an inclined plate and an end sheet; the substrate is provided with a first hollow rupture; the inclined plate is provided with a first connecting side which is connected with one side of the first rupture, so that an angle is formed between the inclined plate and the substrate; the inclined plate is provided with a second hollow rupture; and the end sheet is provided with a second connecting side which is connected with one side of the second rupture, so that an angle is formed between the end sheet and the inclined plate and the end sheet is parallel to the substrate. The artificial intervertebral disk which is provided with the displacement spring is provided with an upper end plate, a lower end plate, a nuclear body and a joint body, wherein the upper end plate and the lower end plate are connected with a lower side plane and an upper side plane of the vertebral body; the nuclear body is matched and tightly contacted with the joint body and arranged between the upper end plate and the lower end plate. Therefore, the artificial intervertebral disk has wide motion angle and the function of buffering the axial pressure.

Description

technical field [0001] The invention relates to a displacement reed and an artificial intervertebral disc with the displacement reed, in particular to a displacement reed which uses the displacement reed to buffer axial pressure and an artificial intervertebral disc with the displacement reed. Background technique [0002] As the human body ages, the organs and other structures of the human body will gradually degenerate over time. As far as the spine is concerned, the intervertebral disc is one of the structures that are most likely to degenerate with age. The intervertebral disc is the main connection and support structure between the vertebral body and the vertebral body. It is also the main buffer structure when the spine bears the axial impact force. The symptoms include local soreness of the patient's body, numbness and weakness of the limbs, neuralgia, paresthesia or functional impairment, etc., which will bring extreme pain to the patient. discomfort. [0003] When...
