[0002] Bone cement is a biomaterial with self-setting properties, which is often used to fill the gap between bone and implant or in bone cavity. When treating painful vertebral diseases, such as osteoporotic vertebral compression fractures, a fine needle can be inserted into the fractured vertebra under the guidance of imaging equipment to inject bone cement into the diseased vertebra to increase the compressive strength of the vertebra, improve spinal stability, relieve or eliminate pain, and prevent vertebral collapse. The bone cement syringe is a medical device specially used for orthopedic surgery. It plays a vital role in mixing and delivering bone cement to the human body.
