Description
Technical field
The present invention relates to medical instruments field, refer more particularly to the bone cement stirring used in a kind of vertebral body balloon expansion plasty and inject system.
Background technology
Vertebral body balloon expansion plasty is a Minimally invasive procedure operation, be mainly used in the treatment of compression fracture of vertabral body, compression fracture of vertabral body is the modal complication of sufferers of osteoporosis face, can cause local pain, moving obstacle, and serious also can cause lower extremity paralysis.First vertebral body balloon expansion plasty carries out the height expanding to recover disease damage vertebral body by sacculus, and the interior implants such as bone cement of injecting of backward pathological changes vertebral body are filled, thus strengthen the strength and stability of pathological changes vertebral body, make the vertebral body after recovery can not again by compression.
Commonly in prior art inject system as shown in Figure 1, the bone cement after bone cement mixer adds the common of the system of injecting and injects in external member 16, by turning handle 17, injects bone cement and flows out from bone cement outlet 18.But existing bone cement mixer and the system of injecting are two parts, need by bone cement mixer by after bone cement stirring, then pass in the system of injecting, such operating process more complicated; And bone cement easily solidifies, when time controling is bad, when bone cement not yet injects pathological changes vertebral body from the system of injecting, will solidify, cause operation to be difficult to carry out.
In addition, inject system bone cement outlet limited length due to existing, doctor operates to inject in systematic procedure and is subject to a large amount of radiation in ward, although protective plate can be adopted to protect, still there is certain potential safety hazard.
Summary of the invention
In view of the above-mentioned defect of prior art, the object of this invention is to provide a kind of easy to operate, reliability is high and integrate stirring, the bone cement stirring of injecting injects system.
The object of the invention is to be achieved through the following technical solutions:
A kind of bone cement stirring injects system, this system primarily of spiral handle, bone cement mixer, bone cement injection tube and bone cement outlet composition, casing assembly is fixedly connected with by multiple thread with primary tank, casing assembly inside arranges stirring passage component, casing assembly is fixedly connected with stirring passage component, stir passage component inside and stirring movable part is set, stir movable part to be slidably connected with stirring passage component, and at stirring movable part, stir between passage component and O type circle is set, spiral handle is connected with stirring movable part spiral, the screw thread of spiral handle is set to anti-back screw thread, spiral handle is arranged spiral handle locating ring, the lower end of spiral handle is fixedly connected with piston, piston and stirring movable part compact siro spinning technology, piston is arranged two annular grooves, and O type circle is set respectively in two annular grooves, piston is made to keep sealing with stirring movable part, the lower end of stirring movable part is fixedly connected with blade, primary tank inside is arranged injects spout assembly, primary tank and inject between spout assembly O type circle is set, primary tank exit arranges outlet flat seal, and primary tank lower end arranges agitator connecting interface, is used for connecting bone cement mixer and bone cement injection tube, the inner plane of agitator connecting interface is against the projection of injecting spout assembly.
Further, primary tank upper and lower side arranges agitator locating ring, agitator locating ring respectively, is used for limiting spiral handle and stirring the position of movable part, to guarantee to stir in bone cement mixer.
Further, twitch spiral handle up and down, drive piston, blade, stirring movable part to move up and down together.
Further, be rotated down spiral handle, spiral handle drives piston to puncture and injects spout assembly, enters into bone cement injection tube inner.
