Detailed Description

The utility model is further illustrated by the following figures and examples, which are not intended to be limiting.

Examples: the utility model provides a device for backbone operation location, includes needle tubing 1 and gunpowder pad pasting 2, and the gunpowder pad pasting specifically can adopt year ropivacaine pad pasting, as shown in fig. 1 and 2, before carrying out puncture location, need to paste the pad pasting in patient's position that needs the operation, wait for the gunpowder on the pad pasting to play a role, puncture again, the afterbody of needle tubing 1 is equipped with needle tail cover 3, the cover has cutting knife 4 on the needle tubing 1, the upper end of cutting knife 4 just passes the needle tubing and is equipped with handle 5.
