[0005] An inter spinous ligament puncture single lumbar anesthesia guiding needle, comprising handle and needle tube, the top end of needle tube is fixedly connected with the bottom end of handle, the inside of the top end of needle tube is provided with chamfered hole;The outside of needle tube is provided with multiple groups of scale lines at equal intervals.

[0006] Further, the top end of handle is provided with through hole, and the inside of the bottom end of through hole is provided with tapered hole that is transitioned to the top end of needle tube.

[0007] Further, the top end of needle tube is fixedly connected with handle in a bonding mode.

[0008] Further, the bottom end of needle tube is provided with puncture head.

[0009] Further, the needle tube is made of medical stainless steel.

[0010] Further, the handle is made of plastic.

[0011] Compared with the prior art, the utility model has the beneficial effects that:

[0012] The utility model discloses a chamfer hole is arranged to the top inside of needle tube, can be realized in use, it is convenient for the waist anaesthetic needle to be inserted fast and smoothly, is not easy to jam, can effectively improve the insertion efficiency and reduce the operation difficulty of waist anaesthetic needle, a plurality of graduation lines are arranged to the outside of needle tube, can be convenient for the depth of penetration of needle tube to be measured fast when puncturing, so that the medical staff knows in time, to improve the precision of operation.
