Abstract

The invention discloses a puncture bone grafting system, which comprises a puncture needle guard component, a puncture core component, a sampling sleeve component, a sampling inserting rod component and a bone grafting funnel, wherein the puncture core component can be placed in the puncture needle sleeve component; the sampling sleeve component can be inserted in the puncture needle guard component; the sampling inserting rod component can be inserted in the sampling sleeve component; and the bone grafting funnel can be connected to the puncture needle guard component. The puncture bone grafting system disclosed by the invention has the beneficial effects that the puncture bone grafting system disclosed by the invention can shorten a time of sampling and bone grafting, so that pain in patients due to an operation is relieved.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, in particular to a puncture bone graft system, which is suitable for orthopedic surgery. Background technique [0002] Osteoporosis, or osteoporosis, is a group of bone diseases caused by various reasons. Bone tissue has normal calcification, calcium salt and matrix are in a normal ratio, and a metabolic bone disease characterized by a decrease in the amount of bone tissue per unit volume. . In most osteoporosis, the reduction of bone tissue is mainly due to increased bone resorption. It is characterized by bone pain and easy fracture. The most common symptom of primary osteoporosis is low back pain, which accounts for 70%-80% of pain patients. The pain spreads along the spine to both sides, and the pain is relieved when lying on the back or sitting. Generally, pain can occur with bone loss of more than 12%. In the elderly with osteoporosis, the vertebral body is compressed and de...
