A kind of novel sacral canal puncture needle, including outer needle handle, outer needle tubing, interior needle handle, inner needle tube, extend hose, outer tube,
Spring, the outer needle handle are hollow cylinder structure, and front end and outer needle tubing integrally connected are simultaneously connected to, and tail end outer wall is equipped with annular
Protrusion；The needle point of outer needle tubing is blunt nosed；The interior needle handle is hollow cylinder structure and is located in outer needle handle, front end and inner needle tube
Integrally connected is simultaneously connected to；The front end of the inner needle tube is inserted into outer needle tubing by outer needle handle tail end and extended outer needle tubing head end, interior
The needle point of needle tubing is sharp head；Described extension hose one end is connected to interior needle handle tail end and communicates therewith, and the other end constitutes syringe
Connector；The outer tube be arranged outside inner needle tube and head end be open the closed concentric drums of tail end；Outer needle handle tail end is just
It protrudes into the annular chamber formed between outer tube and interior needle handle and can slide wherein；It is equipped in outer casing head end outer for preventing
The annular plug that annular protrusion is deviate from from annular chamber on needle handle；The spring is located in outer needle handle and is set in inner needle tube tail end.
Further, the annular protrusion and outer sleeve inner wall clearance fit.
Further, the spring diameter is less than interior needle handle diameter.
Further, the outer tube is wholely set with interior needle handle.
Further, the annular plug is threaded in outer tube head end.
Further, to prevent liquid leakage, sealing ring is additionally provided with inside outer needle handle, the sealing ring is set in interior needle
Pipe tail end and between spring and outer needle handle front end.
Further, the sealing ring is fixed on the inner wall of outer needle handle front end.
Further, the sealing ring is elastic rubber ring.
The utility model beneficial effect is: structure is simple, easy to operate, and good level can be obtained when operating with
Sense and breakthrough sense, and will not surprisingly wear out dural sac or stab blood vessel.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of novel sacral canal puncture needle of utility model in its natural state；
Fig. 2 is a kind of structural schematic diagram of the novel sacral canal puncture needle of utility model under puncture state；
As shown in the figure: the outer needle tubing of the outer needle handle of 1-, 2-, 3- inner needle tube, 4- annular protrusion, needle handle, 6- annular chamber, 7- prolong in 5-
Long soft-pipe, 8- syringe adapter, 9- outer tube, 10- annular plug, 11- spring, 12- sealing ring.
Specific embodiment
The principles of the present invention and feature are described in further detail with reference to the accompanying drawing, example is served only for solving
Utility model is released, the scope of the utility model is not intended to limit.
As shown in Figure 1 and Figure 2, a kind of novel sacral canal puncture needle of the utility model, including it is outer needle handle 1, outer needle tubing 2, interior
Needle handle 5, inner needle tube 3 extend hose 7, outer tube 9, spring 11, and the outer needle handle 1 is hollow cylinder structure, front end and outer needle
2 integrally connected of pipe is simultaneously connected to, and tail end outer wall is equipped with annular protrusion 4；The needle point of outer needle tubing 2 is blunt nosed；The interior needle handle 5 is sky
Heart tube structure is simultaneously located in outer needle handle 1, and front end and 3 integrally connected of inner needle tube are simultaneously connected to；The front end of the inner needle tube 3 is by outer
1 tail end of needle handle is inserted into outer needle tubing 2 and extended 2 head end of outer needle tubing, and the needle point of inner needle tube 3 is sharp head；The extension hose 7 one
End is connected to interior 5 tail end of needle handle and communicates therewith, and the other end constitutes syringe adapter 8；The outer tube 9 is to be arranged in inner needle tube
