The application process of integrated bone cement electric stirring propulsion plant, its concrete steps are:
(1) back out protecgulum, bone cement two component inserted and stirs in cavity, after to screw on protecgulum; Back out front block, guess front driving handle, after air-out, block a shot before screwing on;
(2) switch on opening handle handle, now micromotor energising starts to rotate and drives connected stirring vane to rotate, and timer starts to record mixing time; Reach with its mixing effect after (observing its mixing effect by transparent cavity), or arrive and preset after mixing time, closing switch, stops stirring and timing;
(3) front block is backed out, spill female Luer, be connected with the female Luer of other supporting Cement fixation devices (or other medical apparatus and instruments), after connecting, get final product driven forward handle, in this process, stirring vane can fold, and can be observed the amount of injection by the scale of cavity; Inject complete, this device is separated with Cement fixation device (or other medical apparatus and instruments).
Compared with prior art, good effect of the present invention is:
(1) this device can complete and stirs and inject two processes.
(2) drive end bearing bracket is furnished with female Luer to be connected with necessaries, directly being injected by bone cement needs position, easy to operate, shorten operating time, alleviate patient suffering, require relatively to reduce to the skill of operation, reduce working doctor intensity, perform the operation safer.
(3) collapsible blade is with propelling, and extraction folds, and porose on folding blade, can effectively make bone cement mix homogeneously.
(4) stir on cavity and have scale, operator can easily locate intuitively.
(5) micromachine and whole device one, by the cell powers in control box, facilitate doctor to operate.
