Abstract

The invention discloses a fusion cage device with bone cement screws for lumbar interbody fusion. The fusion cage device comprises a fusion cage body; the fusion cage body is provided with two fixing holes, and the fixing holes are obliquely arranged; the fixing holes are used for the screws penetrate through, and the screws can be connected with a vertebral body; a flow channel is arranged in each screw; the flowing channels can be connected with a filling assembly; and under the action of the filling assembly, bone cement is filled to a position where the screws and the vertebral body are connected along the flowing channels. The oblique screws are arranged on the fusion cage body, so that the stability of connection between the fusion cage body and the vertebral body is guaranteed, and rehabilitation of the lumbar vertebra is guaranteed; meanwhile, filling of the bone cement is achieved through the filling assembly, so that connection between the screws and the vertebral body is guaranteed, rehabilitation of a patient is further guaranteed, and by such arrangement, the stability of the lumbar vertebra is guaranteed, the fusion area is enlarged, and efficient lumbar vertebra treatment is realized.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to a fusion device with bone cement screws for lumbar intervertebral fusion. Background technique [0002] With the aging of the population, spinal degenerative diseases with neck and shoulder pain and low back pain as the main symptoms are seriously affecting people's work and life. Intervertebral body fusion is one of the main methods for the treatment of spinal degenerative diseases. [0003] Through the unremitting efforts of scientists, various intervertebral fusion devices have been developed and gradually applied clinically. An ideal intervertebral fusion device requires the ability to correct spinal deformities, restore normal physiological curvature, maintain the stability of the intervertebral space, and most importantly, promote bone fusion. However, the scope of application of intervertebral fusion devices does not include patients with osteoporosis, and there are still...
