Embodiment 1
[0031] This embodiment provides a bone cement automatic propulsion device, which can fill bone cement into the human vertebral body. The structure is as follows: Figure 1~4 As shown, it includes: an automatic driving device 2 and a bone cement propelling device 1. The bone cement propelling device 1 includes a piston 14 for propelling bone cement into the cancellous bone of the human vertebral body. The automatic driving device 2 can drive the piston 14 to move. The drive device 2 has a plurality of propulsion gears, and the thrust of the automatic drive device 2 is different when different propulsion gears are adopted.
[0032]The bone cement automatic propulsion device provided in this embodiment uses the automatic drive device 2 to automatically drive the piston 14 to move, without the need for medical staff to manually propel it in front of the operating bed, so that the medical staff can perform bone cement far away from the operating table and under strict radiation prot...
Embodiment 2
[0051] This embodiment provides a bone cement filling method based on the bone cement automatic propulsion device described in Embodiment 1, including:
[0052] Step 1: Perform bone density and CT scans on the vertebral body to be filled with bone cement before operation; the more serious the osteoporosis and osteolytic changes of the vertebral body, the smaller the bone density, especially the more serious the surrounding wall damage and fracture, the required the smaller the thrust;
[0053] Step 2: Set the advancing gear of the automatic driving device 2 according to the degree of osteoporosis of the vertebral cancellous bone and the degree of bone destruction caused by osteolytic changes.
