Bone cement stirring and injecting system

Abstract

The invention relates to a bone cement stirring and injecting system. The bone cement stirring and injecting system mainly comprises a spiral handle, a bone cement stirrer, a bone cement injection cylinder and a bone cement outlet pipe, wherein a stirring channel component is arranged in a housing component; a stirring movable part is arranged in the stirring channel component and connected with the stirring channel component in a sliding manner; a spiral handle positioning ring is arranged on the spiral handle; the lower end of the spiral handle is fixedly connected with a piston; the piston is in close connection with the stirring movable part; a blade is fixedly connected to the lower end of the stirring movable part; an injection outlet component is arranged in a main container; an outlet plane sealing part is arranged at the outlet of the main container; and stirrer connecting interfaces are arranged at the lower end of the main container and used for being connected with the bone cement stirrer and the bone cement injection cylinder. The bone cement stirring and injecting system can quickly inject bone cement into a diseased vertebral body, and avoids the phenomenon that solidification occurs when bone cement is not injected into the diseased vertebral body.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a bone cement mixing and injecting system used in vertebral body balloon dilatation and plastic surgery. Background technique [0002] Balloon vertebroplasty is a minimally invasive spinal surgery, mainly used in the treatment of vertebral compression fractures, which is the most common complication in patients with osteoporosis, causing local pain and mobility impairment In severe cases, it can also lead to paralysis of the lower limbs. Balloon dilatation of the vertebral body first expands the height of the damaged vertebral body through balloon expansion, and then injects bone cement and other fillers into the diseased vertebral body for filling, thereby enhancing the strength and stability of the diseased vertebral body and enabling recovery. The posterior vertebral body will no longer be compressed and deformed. [0003] Common bolus injection systems in the prior art such a...

Problems solved by technology

However, the existing bone cement mixer and injection system are two parts, the bone cement needs to be stirred by the bone cement mixer, and then passed into the injection system, so the operation process is more complicated; moreover, the bone cement is easy to solidify , when the time control is not good, the bone cement will solidify before it is injected into the diseased vertebral body from the injection system, making it difficult to perform the operation

[0004] In addition, due to the limited length of the bone cement outlet tube of the existing bolus injection system, doctors are exposed to a large amount of radiation during the operation of the bolus injection system in the ward. Although protective plates can be used for protection, there are still certain potential safety hazards
