Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1: referring to fig. 1 to 4, a puncture needle and a fixing device thereof are disclosed, the puncture needle comprises a puncture needle and a puncture needle fixing seat, the puncture needle comprises a needle head 11, a needle seat 10 is arranged at the top of the needle head 11, an inverted truncated cone-shaped boss 9 is arranged at one side of the needle seat 10 facing the needle head 11, the puncture needle fixing seat comprises a truncated cone-shaped positioning seat 1, an inverted truncated cone-shaped boss groove 4 is arranged at the central position of the positioning seat 1, the boss 9 is matched with the boss groove 4 in a clamping manner, a circular contact piece 2 is arranged at the bottom of the positioning seat 1, and a glue layer 3 is coated at the bottoms of the contact piece 2 and the positioning seat 1.
