Fig. 1 is structural representation of the present utility model.
Fig. 2 is the right TV structure schematic diagram of the rotatable state of Fig. 1.
Fig. 3 is the right TV structure schematic diagram of Fig. 1 gripping orientation.
Detailed description of the invention
Below in conjunction with specification drawings and specific embodiments, this utility model is further illustrated.
As shown in Figure 1, 2, 3, this utility model comprises head hoop 1, rotating mechanism and clamping body.
Described rotating mechanism comprises disk 2, ring frame 3, gear 4 and support bar 5, described disk 2 one side is fixedly connected with the side of ring frame 3, the circle centre position of disk 2 is fixedly connected with central shaft 6 one end, the other end of central shaft 6 is rotatably connected on the upper end of support bar 5, and support bar 5 lower end is used for being fixedly connected on bed board 7.
Described disk 2 has a manhole, is rotationally connected a rotating shaft 8 in described manhole, described rotating shaft 8 one end is fixedly connected with a crank 9, and the other end is connected with gear 4 key through manhole.Described ring frame 3 medial wall is fixedly connected with a circle arc-shaped rack, and described gear 4 is meshed with the arc-shaped rack on ring frame 3, and shake crank 9 driven gear 4 rotates, and then drives the rotation of ring frame 3 by arc-shaped rack.Described ring frame 3 edge is fixedly connected with head hoop 1 by multiple connecting rod 10.
Described head hoop 1 is for having the loop configuration of opening, head hoop 1 opening part one end is connected with a buckle by elastic band 11, the other end connects a cutting ferrule, during use, patients head is put into head hoop 1, head hoop 1 is made to be enclosed within patient's forehead place, then stick in cutting ferrule by buckle, patients head can be fixed in head hoop 1, the existence of elastic band 11 can adapt to the head varied in size in certain limit.On the same line, the rotation of such ring frame 3 can drive the rotation of head hoop 1 in the center of circle of described head hoop 1, disk 2 and ring frame 3, thus the convenient rotational angle changing patients head, reach best surgery location.
Described clamping body comprises electric magnet 14, bar cover 13 and magnetic shaft 15, described electric magnet 14 is fixedly mounted on disk 2, described electric magnet 14 sidewall is fixedly connected with hollow stem cover 13 on the direction of gear 4, described magnetic shaft 15 is in bar cover 13, its bar end matches with the teeth groove of gear 4, described cooperation is the teeth groove that the end of magnetic shaft 15 can stretch into gear 4, sticks into and limiting gear 4 effect of rotating to reach.Described electric magnet 14 is connected with a control circuit circuit, is energized to electric magnet 14, and electric magnet 14 pairs of magnetic shaft 15 produce contrary repulsive force, by magnetic shaft 15 push-off pin cover 13, make between its two teeth being stuck in gear 4, now gear 4 is fixing no longer rotates, and namely head hoop 1 is fixed.Change polarity by control circuit to electric magnet 14, electric magnet 14 pairs of magnetic shaft 15 produce suction, and magnetic shaft 15 is fallen back to again in bar cover 13, and now gear 4 can arbitrarily rotate, and namely head hoop 1 can rotate.Described control circuit is connected with control knob circuit, and control the pole of electric magnet 14 to change by control knob, described control knob can be arranged on the described surperficial side of disk 2.The control circuit that described electric magnet changes polarity is common practise in the industry, is not repeated herein.
When carrying out operation technique, first patients head is put into head hoop 1, as changed the rotational angle of patients head in operation process, regulable control button, makes electric magnet 14 pairs of magnetic shaft 15 produce suction, remove the spacing of magnetic shaft 15 pairs of gears 4, rotate crank 9, when patients head forwards suitable position to, regulable control button, make electric magnet 14 pairs of magnetic shaft 15 produce repulsion, gear 4 is blocked by magnetic shaft 15.Operation uses simple, time saving and energy saving, frequently stirs patients head back and forth, accelerate procedure without the need to medical worker.
It should be noted that; particular of the present utility model has been described in detail this utility model; for a person skilled in the art, the various apparent change carried out it when not deviating from spirit and scope of the present utility model is all within protection domain of the present utility model.
