Abstract
The utility model discloses a bone cement injector. The bone cement injector comprises an injection needle cylinder, a puncture needle and a pressing cylinder, wherein the puncture needle is arranged at the front end of the injection needle cylinder; the pressing cylinder is arranged at the rear end of the injection needle cylinder and communicated with the injection needle cylinder through a catheter; a tubular cavity is formed in the injection needle cylinder; a piston is arranged in the cavity; a connecting seat penetrating through the injection needle cylinder and connected with the puncture needle is arranged at the front end of the cavity; a pressing piston and a pressing piston rod are arranged in the pressing cylinder; the front end of the pressing piston rod is connected with the pressing piston; the rear end of the pressing piston rod is connected with a handle; and convex grains are arranged on the surface of the handle. By adopting the bone cement injector, the puncture needle is prevented from being separated from the injection needle cylinder due to over high pressure when bone cement is injected; the operation is stable, and the injection dose can be accurately controlled; and the whole injector is easy to detach and convenient to clean.
Description
Technical field
This utility model belongs to medical instruments field, relates to a kind of pyramid plastic operation apparatus, specifically a kind of bone cement injector.
Background technology
Pyramid plastic operation is former of compression fracture of vertabral body, vertebral body causing for osteoporosis or the treatment operation of the bone diseases such as metastatic tumo(u)r, myeloma, it is a kind of non-blood vessel interventional therapy method under the irradiation image guiding, the method is passed through percutaneous puncture, bone cement is expelled in diseased vertebral body, stablize vertebral body, thereby reach the purpose for the treatment of.
The injected dose precision of general bone cement injector is not very accurate, and the macro adjustments and controls the when unstability of its operation and injection are desirable not to the utmost.
