Problems solved by technology
The traditional operation is to implant artificial vertebral body (or titanium mesh), and at the same time supplement it with nail rod system (or steel plate) for fixation treatment. The existing technology itself cannot form fixation with human vertebral body. The high postoperative notch of the nail-rod system (or steel plate) implanted into the human body leads to aggravated postoperative discomfort for patients, and the surgical risk is high. When the nail-rod system (or steel plate) fails to fix, the vertebral body replacement operation fails, causing greater harm to the patient. In the later stage, a second operation is required to remove the nail-rod system (or steel plate) used for fixation, which not only increases the cost, but also requires the patient to bear the pain of the second operation

The present invention discloses a zero-incisure adjustable artificial vertebra. The zero-incisure adjustable artificial vertebra comprises an artificial vertebra body. The upper end of the artificialvertebra body is provided with an upper vertebra body end cover, and the lower end of the artificial vertebra body is provided with a lower vertebra body end cover. The upper vertebra body end cover and the lower vertebra body end cover are respectively provided with an upper connecting piece and a lower connecting piece that are connected to the human bone. The artificial vertebra body is provided with a vertebra body height adjusting device. The zero-incisure adjustable artificial vertebra of the present invention is reasonable in design, easy to implant, expand and compress, capable of being adjusted to meet a suitable height, beneficial to restore the normal height of a diseased vertebral segment, and beneficial to the fusion and stability of the vertebral segment in the later stage. The zero-incisure adjustable artificial vertebra of the present invention reduces pain caused by secondary operation and greatly reduces secondary operation cost for patients.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a zero-notch adjustable artificial vertebral body. Background technique [0002] It is known that the artificial vertebral body has been widely used clinically as a kind of effective vertebral body substitute, 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 Kyphosis deformity with very good results for spinal stabilization reconstruction. [0003] Currently, for patients with cervical spine, thoracic spine or lumbar spine who have vertebral body (or most of the vertebral segments) defects caused by lesions (mainly tumors) or trauma, the vertebral bodies surgically resected due to lesions are included. The traditional operation is to implant artificial vertebral body (or titanium mesh), and at the same ti...
