Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further.
Embodiment 1: as Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, this utility model is achieved in that a kind of lumbar puncture needle, comprise footstock 1, the two ends, left and right of described footstock 1 bottom surface are respectively provided with a pole 2, the bottom of each pole 2 is respectively provided with a base 3, the medial surface of each pole 2 is respectively provided with a slide rail 4, article two, be provided with needle body 6 between slide rail 4, the epimere of the left and right sides of described needle body 6 lateral wall is respectively provided with a slide bar 5, needle body 6 is fixed on slide rail 4 by slide bar 5, described needle body 6 top is provided with boosting bar 9, the top of described needle body 6 lateral wall is provided with a circle groove 15, the bottom of boosting bar 9 inwall is provided with a circle faceplate 16, needle body 6 to be connected with boosting bar 9 by groove 15 and faceplate 16 and to communicate, lower 1/2nd sections of described boosting bar 9 lateral wall are provided with a circle screw thread 10, described boosting bar 9 is arranged on the middle position in footstock 1, the front side of the middle epimere of described boosting bar 9 lateral wall is provided with Pressure gauge 11, the top of the left and right sides of described boosting bar 9 lateral wall is respectively provided with a rotating shaft 14, turning handle 12 is arranged on the lateral wall of boosting bar 9 by rotating shaft 14, a nook closing member 8 is jointly provided with in described boosting bar 9 and needle body 6, described nook closing member 8 is through in boosting bar 9 and needle body 6, the top of described nook closing member 8 is provided with core tail 13, the lateral wall of the nook closing member 8 bottom described core tail 13 is provided with a circle screw thread 10, the lateral wall of described needle body 6 is provided with dial gauge 7.
