[0009] As a preferred scheme of the utility model, the outer wall edge of the puncture wing is set as a sharpened edge.

[0010] The sharpened edge of the outer edge of the puncture wing can directly contact the incision during puncture, thereby avoiding the hooking of the spun fabric and the breakage of the needle body.

[0011] As a preferred scheme of the utility model, the bottom end of the needle column portion is welded to the top end of the connecting portion by ultrasonic welding.

[0012] The ultrasonic welding connection mode can ensure the welding effect, further ensure the compression resistance of the entire needle body, and further avoid the breakage of the needle body.

[0013] As a preferred scheme of the utility model, the needle column portion includes a rod portion and a bent handle portion at the top end of the rod portion.

[0014] The utility model provides a non-woven needle for preventing needle breakage.

[0015] The non-woven needle for preventing needle breakage can ensure the overall rigidity of the support column portion, the three groups of puncture wings, and the sharpened outer end of the puncture wing, ensure the smooth puncture effect, and further ensure the rigidity of the needle by the ultrasonic welding connection mode, thereby solving the problem of the compression breakage of the existing needle.
