Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

As shown in fig. 1-3, the utility model provides a puncture device for anesthesia, which comprises a needle handle 1 and a puncture device 4 detachably connected with the needle handle 1:

the bottom of the needle handle 1 is provided with a hollow thread groove 11, the inner wall of the thread groove 11 is screwed with a hollow thread column 42, and the thread column 42 is arranged at the top of the puncture needle cap 41.
