Abstract

The invention relates to the technical field of medical instruments, and discloses an osteoporosis type locking spinal fusion cage, which comprises a lower spinal fusion cage body, a comfortable buffering device is connected to the middle of the upper surface of the lower spinal fusion cage body, and an upper spinal fusion cage body is arranged above the lower spinal fusion cage body; a gap stable adjusting device is arranged on one side of the lower spine fusion cage, bolt inclined holes are formed in one side of the lower spine fusion cage and one side of the upper spine fusion cage, reinforcing rib devices are installed in the middle of the lower spine fusion cage and the middle of the upper spine fusion cage, and telescopic racks are installed in the comfortable buffering device. According to the osteoporosis type locking spinal fusion cage, the reinforcing rib device and the comfortable buffering device are arranged to be used in cooperation, the buffering effect can be achieved in the moving process of a user, the spine gap connecting position of the user cannot be stiff or painful, and the user can conveniently and rapidly move the spine through cooperation of the telescopic rack and the gap stable adjusting device. The transmission adjusting process can be simple, convenient, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an osteoporotic locking spinal fusion device. Background technique [0002] Osteoporosis, or osteoporosis, is a group of bone diseases caused by a variety of reasons. Bone tissue has normal calcification, and the ratio of calcium salt to matrix is ​​normal. It is a metabolic bone lesion characterized by a decrease in the amount of bone tissue per unit volume. , Osteoporosis can occur in different genders and at any age, but it is more common in postmenopausal women and elderly men. It is characterized by bone pain and easy fracture. The fixation of the vertebral body, so as to get rid of the limitation of auxiliary fixation, for some patients with osteoporosis, it is necessary to use a locking spinal fusion device for surgical treatment of the spine. [0003] China's authorized invention publication (announcement) number: CN211187664U discloses a kind of osteoporotic loc...
