Abstract

The invention provides a remotely-controlled bone cement injection device. The remotely-controlled bone cement injection device comprises a remote control unit, a control unit, a driving unit and an injection flow monitoring unit; the remote control unit comprises a remote controller and a monitor, the remote controller is connected with the input end of the control unit, and the monitor is connected with the output end of the control unit; the output end of the control unit is connected with the input end of the driving unit, and the output end of the driving unit is connected with the input end of the injection flow monitoring unit. The remotely-controlled bone cement injection device is simple in structure and convenient to operate and can not only achieve real-time monitoring on the injection dose and speed of an injector, but also effectively avoid radiation damage to a doctor in the operation process.

Description

technical field [0001] The invention belongs to the field of biomechanical injection, in particular to a bone cement remote control injection device. Background technique [0002] Osteoporosis, which is common among middle-aged and elderly people, may lead to vertebral compression fractures. In vertebroplasty (PVP), the doctor injects bone cement into the fractured spine of the patient. After the bone cement solidifies, it can support and strengthen the vertebral body and relieve pain; Due to the limitation of surgical equipment, X-ray machines are often used to see through the injection site in clinical practice to observe the injection volume and leakage. Doctors will be exposed to radiation during the operation and will be harmed by radiation. At present, many companies at home and abroad have conducted a lot of research on bone cement injection devices. [0003] Stryker (USA) Medical Devices Co., Ltd. discloses an integrated mixing and delivery system, which requires n...
