Problems solved by technology

[0003] The bone cement propulsion device is a device that propels the bone cement that has been kneaded before the curing period into the vertebral cancellous bone with osteoporosis and osteolytic changes in the human body for filling. However, the existing bone cement propulsion devices are all Manual advancement requires medical staff to operate in front of the operating bed, and the injection of bone cement needs to be carried out under fluoroscopy throughout the entire process, which inevitably causes medical staff to be exposed to long-term radiation from the fluoroscopy equipment; If bone cement is advanced without fluoroscopy, serious complications such as leakage of bone cement into the spinal canal may occur, which greatly reduces the safety of bone cement surgery

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.

Abstract

The invention provides an automatic bone cement propelling device and a bone cement filling method, and relates to the technical field of medical equipment.The automatic bone cement propelling device comprises an automatic driving device and a bone cement propelling device.The bone cement propelling device comprises a piston used for propelling bone cement into cancellous bones with osteoporosis and osteolysis change of the human body; the automatic driving device can drive the piston to move, the automatic driving device is provided with a plurality of pushing gears, and the pushing force of the automatic driving device is different when different pushing gears are adopted. According to the automatic bone cement propelling device provided by the invention, controllable and continuous automatic propelling of the bone cement is realized when medical personnel are far away from an operating table and under strict radiation protection, and long-time ray radiation of the medical personnel in a traditional operation is avoided; and different pushing gears can be selected according to the preoperative bone destruction degree, so that the bone cement injection safety and the operation quality are greatly improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an automatic propulsion device for vertebral bone cement and a bone cement filling method. Background technique [0002] Bone cement is a medical material used in orthopedic surgery, which is made by mixing polymethyl methacrylate (white powder) and colorless monomer methyl acrylate (liquid) with a pungent smell. When using, just pour them together according to a certain proportion and adjust them. After the mixing period, sticking period, dough period and curing period, the bone cement undergoes polymerization and solidification reaction, and solidifies and forms. The whole process only takes more than ten minutes. [0003] The bone cement propulsion device is a device that propels the bone cement that has been kneaded before the curing period into the vertebral cancellous bone with osteoporosis and osteolytic changes in the human body for filling. However, the existin...
