The working principle of the technical scheme is as follows: in order to realize that the medical staff can conveniently use the first control mechanism 10 and the second control mechanism 11, in this embodiment, a first sliding groove 52 and a second sliding groove 53 are respectively arranged on two holding rods 51 of the handle 5, the first driving mechanism 10 is installed in the first sliding groove 52, the second driving mechanism 11 is installed in the second sliding groove 53, when the medical staff uses the first driving mechanism 10 for driving, when the first clamping rod 102 is in the first clamping groove 54, the outer plate 81 is in an oblique state facing the closed end 3, the first clamping rod 102 in the second driving mechanism 11 is in the fourth clamping groove 57, at this time, the medical staff uses the filling push rod 2 to push the bone cement in the filling sleeve 1, and the bone cement is injected backwards in a directional manner through the outer plate 81 and the movable plate 92; when the first catch lever 102 is in the second catch groove 55, the outer plate 81 is perpendicular to the axis of the filling cannula 1, the first catch lever 102 in the second driving mechanism 11 is in the fifth catch groove 58, and the movable plate 92 is received in the second cavity 14, at this time, the medical staff uses the filling push rod 2 to push the bone cement in the filling cannula 1, and the bone cement is injected upwards through the outer plate 81; when the first catch lever 102 is in the third catch groove 56, the outer plate 81 is in an inclined state away from the closed end 3, the first catch lever 102 in the second driving mechanism 11 is in the fifth catch groove 58, and the movable plate 92 is received in the second cavity 14, at which time the medical staff pushes the bone cement in the filling cannula 1 by using the filling push rod 2, and the bone cement is injected forwardly and directionally through the outer plate 81.
The beneficial effects of the above technical scheme are that: through the design of the structure, the
In one embodiment, further comprising: automatic propeller and multiaxis arm (not shown), automatic propeller sets up on the free end of multiaxis arm, automatic propeller includes box, electric putter and controller, be provided with the through-hole on the left side wall of box, electric putter's push rod passes the through-hole, be provided with the scale mark on the push rod, and be provided with splint on the free end of push rod, splint are used for connecting
The working principle of the technical scheme is as follows: in the embodiment, the bone cement propeller of the vertebral body forming system is provided with the automatic propeller and the free end of the multi-axis mechanical arm, the automatic propeller is arranged at the free end of the multi-axis mechanical arm, and medical personnel use the control mechanism of the multi-axis mechanical arm to adjust the automatic propeller, so that the multi-axis mechanical arm can adjust the automatic propeller to a proper spatial position; after bone cement propeller of centrum forming system entered into patient's disease position, medical personnel will fill pushing away the handle on the
The beneficial effects of the above technical scheme are that: through the design of above-mentioned structure, provided automatic propeller and multiaxis arm in this embodiment, automatic propeller can replace medical personnel's manual operation to promote and fill
