The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1 and Figure 2, the present invention includes the base 13 of the installing hole 12 that has perforation, the downside of base 13 is equipped with foam-rubber cushion 14, in order to be fixed on different body surfaces; Rotating disk 11 is installed on the base 13; Described rotating disk 11 tops are connected with down free bearing 10, and last free bearing 8 is hinged by bearing pin and following free bearing 10, also are provided with on the following free bearing 10 and can lock described first locking nut 9 of going up free bearing 8; Slide unit 1 is connected on the free bearing 8, and two end devices of slide unit 1 have preceding connecting plate 1-1 and back connecting plate 1-2; Between connecting plate 1-1 and the back connecting plate 1-2 fixing optical axis 2 and rotating leading screw 7 are installed before described, leading screw 7 is connected with the motor 5 of device on the connecting plate 1-2 of back; One side of puncture needle mount pad 3 is enclosed within on the optical axis 2, and opposite side is bolted on the described leading screw 7; Puncture needle mount pad 3 is provided with down mounting groove 4; Clamping seats 17 is connected in the top of puncture needle mount pad 3 by bolt 16, and the downside of clamping seats 17 is provided with corresponding last mounting groove 18, and last mounting groove 18 and following mounting groove 6 can surround formation hole 19.
As shown in Figure 3, Figure 4, the edge of rotating disk 11 has flange 111 vertically downward, and the below of rotating disk 11 also has first flange 111; The upside of base 13 is provided with second flange, 131, the second flanges 131 between first flange 112 and flange 111, and rolling bearing (described rolling bearing does not draw) is installed between first flange 112 and second flange 131; Described flange 111 is provided with screwed hole radially, is connected with second locking nut 15 in the described screwed hole, and tightening second locking nut 15 can be so that the outside butt of its end and second flange 131, thus the rotation of restriction rotating disk 11.
