Abstract

The invention relates to a bone filler conveying sleeve which comprises a conveying tube, a conveying tube handle and a sheath core. A flexible tube is arranged at a far end of the conveying tube, a rigid tube is arranged at a near end of the conveying tube, a near end of the flexible tube is fixedly connected with a far end of the rigid tube, a near end of the rigid tube is fixedly connected with the conveying tube handle, the sheath core is slidably inserted into the conveying tube, a near end of the sheath core is fixedly connected with an adjusting handle, and a far end of the sheath core is bent to form a fixed angle which is a fixed bent section of the sheath core. The far end of the conveying tube of the bone filler conveying sleeve is provided with the flexible tube, and the sheath core with the fixed angle formed at the far end is inserted into the conveying tube, so that the purpose of controlling the bending degree of the far end of the conveying tube can be achieved by controlling the relative positions of the fixed bent section of the sheath core and the flexible tube at the far end of the conveying tube, and the bone filler conveying sleeve is convenient to operate, simple in structure and low in cost.

Description

technical field [0001] The present invention relates to a bone filler delivery sleeve, in particular to a bone filler delivery sleeve used in percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP). Background technique [0002] Vertebral compression fractures caused by osteoporosis are more common in the elderly, and with the deepening of aging, the number of patients suffering from this disease is also increasing rapidly, and percutaneous vertebroplasty (PVP) or percutaneous vertebral body Kyphoplasty (PKP) played an irreplaceable role in it. At present, bone filler delivery sleeves are widely used in vertebroplasty. Under the monitoring of imaging equipment, fillers (such as bone cement) are injected into the cancellous bone space of the vertebrae with the help of external force to restore the height of the vertebral body and enhance The strength and stability of the vertebral body, relieve the pain of the patient's back, so as to treat the compression fractu...
