Abstract

The invention discloses an automatic bone cement mixing and injecting device for vertebroplasty, and relates to the field of medical instruments, the automatic bone cement mixing and injecting device comprises an adjusting device, a stirring device and an injecting device, the adjusting device is vertically and fixedly mounted on the ground and provides a mounting platform for other devices, the stirring device is fixedly mounted on the adjusting device, and the injection device is fixedly installed below the stirring device, the adjusting device can adjust the injection angle so that a patient can meet an operation in a more comfortable posture, the stirring device can fully stir bone cement needed by the operation, and the injection device is used for injecting the stirred bone cement into a human body. According to the invention, stirring and injection can be simultaneously carried out, and the injection angle can be randomly adjusted.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a bone cement automatic mixing and injection device for vertebroplasty. Background technique [0002] Vertebroplasty, the clinical full name is percutaneous puncture vertebroplasty, which is a minimally invasive operation. It is a technique to strengthen the vertebral body by injecting bone cement (polymethyl acrylate, or artificial bone) into the diseased vertebral body. But the existing The bone cement mixing is usually manually mixed and then injected, which is easy to cause pollution. Therefore, there is an urgent need for an automatic bone cement mixing and injection device for vertebroplasty. [0003] Application CN201420003695.4 discloses a bone cement injection device. Its technical scheme is: a high-pressure injection cylinder is provided, a push rod is provided at the rear of the high-pressure injection cylinder, and an injection needle is provided at the front end of the...
