Detailed description of the invention
Merogenesis puncture needle as shown in Fig. 1 ~ 2, Fig. 5, comprise needle tubing 1, inner core 2 and handle 3, have in handle 3 and run through this handle 3 and the jack 301 passed for inner core 2, inner core 2 one end is set to block 21, this block 21 offsets with one end of handle 3, one end of needle tubing 1 is set to tapered tube head 11, and the other end of needle tubing 1 and the other end of handle 3 are fixed removably; The other end of inner core 2 is set to tapered needle 22, and this inner core 2 is stretched out by tapered tube head 11 by tapered needle 22 after inserting jack 301, needle tubing 1 successively.
Tapered needle 22 is stretched out by needle tubing 1, be beneficial to and thrust skin by tapered needle 22, subcutaneous tissue, and, when thrusting subcutaneous tissue, needle tubing 1 plays guide effect by tapered tube head 11, tapered needle 22 again can shutoff tapered tube head 11, prevent blocking and impact is punctured, after puncture certain depth, inner core 2 is extracted from needle tubing 1, and handle 3 is removed from needle tubing 1, only indwelling needle tubing 1, have an X-rayed after doing the puncture of adjacent vertebral pedicle puncture pin percutaneous with method, according to perspective situation, peace is turned round and stretched out the hand handle 3 and is adjusted respectively and deepen to penetrate, until when puncture is satisfied with, extract inner core 2, put into guide pin, guide pedicle of vertebral arch reaming, tapping, put nail, avoid obstruction and interference that time puncture in many places, adjacent handle 3 is subject to simultaneously.
Wherein, during puncture, block 21 is pressed on one end of handle 3, in conjunction with the active force of handle 3, can enter subcutaneous tissue relatively easily by tapered needle 22 and tapered tube head 11.
For reliably leading and stable support to inner core 2, prevent inner core 2 from bending or offseting, as shown in Figure 2, the mounting cylinder 32 that handle 3 comprises grip part 31 and stretched out by the side of this grip part 31, the through hole 311 running through this grip part 31 is had in grip part 31, this through hole 311 is coaxial with the bore of mounting cylinder 32 and communicate, and the bore of this through hole 311 and mounting cylinder 32 forms described jack 301, and inner core 2 obtains effective guide effect in jack 301.The grip part 31 of this example, in oval spherical, also can be set to other arbitrary shapes such as spheroidal.
As shown in figs. 2 to 4, for convenience of the mounting or dismounting of handle 3 with needle tubing 1, the nozzle of mounting cylinder 32 is provided with the radial jointed shaft 321 extended, and the inwall of mounting cylinder 32 is fixed at the two ends of this jointed shaft 321; The other end of described needle tubing 1 has splits groove 12, this is split groove 12 and the other end of needle tubing 1 is separated to form the first fixed lobes 13 and the second fixed lobes 14, the side, bottom of the first fixed lobes 13 has first semicircle orifice 15 through with splitting groove 12, side, bottom away from the second fixed lobes 14 of the first semicircle orifice 15 has second semicircle orifice 16 through with splitting groove 12, this second semicircle orifice 16 is coaxial with the first semicircle orifice 15, and this second semicircle orifice 16 and the first semicircle orifice 15 form the hinge hole (in figure do not mark) that coordinate hinged with jointed shaft 321.When needing to remove handle 3, can first extract inner core 2, now hinge hole coordinates with jointed shaft 321 is hinged, by the handle 3 rotated to an angle, because the first semicircle orifice 15, second semicircle orifice 16 all cannot limit jointed shaft 321 completely, and the first semicircle orifice 15, second semicircle orifice 16 all with split groove 12 and connect, then jointed shaft 321 will enter and split groove 12, realize the disengaging with hinge hole and then convenient dismounting handle 3.In addition, the first fixed lobes 13 can produce mutual elastic acting force with the second fixed lobes 14 under the separation splitting groove 12, to be close to the inwall of mounting cylinder 32, to ensure the steady of articulated manner entirety.
As shown in Figure 4, the first fixed lobes 13 top is provided with the first guiding incline 131 that ecto-entad tilts, and the top of described second fixed lobes 14 is provided with the second guiding incline 141 of ecto-entad inclination.First guiding incline 131 and the second guiding incline 141 are beneficial to and are directed to centering when inner core 2 penetrates needle tubing 1 and enter in the pore of needle tubing 1, and the tapered needle 22 of inner core 2 can be prevented to be damaged by collision.
As shown in Figure 1, Figure 3, the nozzle sidewall of mounting cylinder 32 is provided with two angles 322 for difference empty avoiding first fixed lobes 13, second fixed lobes 14.The setting of two angles 322, be beneficial to handle 3 when rotating, the first fixed lobes 13, second fixed lobes 14 obtains outer of certain angle at two angle 322 places, thus strengthens the width splitting groove 12 and be beneficial to jointed shaft 321 and slip into and split groove 12 and depart from hinge hole smoothly.
For carrying out reliably, effectively leading to inner core 2 further, the tapered needle 22 of inner core 2 is prevented to be damaged by collision, as shown in figures 2-3, guide pipe 323 is stretched out to nozzle at the bottom of the cylinder of mounting cylinder 32, this guide pipe 323 is communicated with described through hole 311, and described inner core 2 inserts needle tubing 1 through after this guide pipe 323.
Above-mentioned embodiment is only the preferred embodiment of the present invention; can not limit the scope of protection of the invention with this, change and the replacement of any unsubstantiality that those skilled in the art does on basis of the present invention all belong to the present invention's scope required for protection.
