Abstract
The utility model relates to a puncture needle belonging to the field of medical apparatus, in particular to a multi-functional puncture needle used for treating cysticercus. The multi-functional puncture needle comprises a needle head, a needle handle and a needle tube used for connecting the needle head and the needle handle. The multi-functional puncture needle is characterized in that a drug injection needle head is arranged in the puncture needle head and is communicated with a drug injection tube arranged on the needle handle via a drug injection tube passage arranged in the needle tube; a suction hole is arranged at the tail end of the needle handle and a drug injection hole is arranged on the lateral wall close to the needle tube; an external bushing which is provided with a suction apparatus is arranged on the needle tube, the suction apparatus comprises a suction tube and the suction hole, the suction tube is arranged on the inner lateral wall of the external bushing and the suction hole is communicated with the suction tube arranged outside the external bushing, switch valves are arranged on the suction hole and the drug injection hole. The multi-functional puncture needle integrates puncture, suction and drug injection as a whole. The arrangement of the suction apparatus on the external bushing effectively prevents the side-overflow of cysticercus fluid during the puncturing process, thus the problems of implantation and cysticercus recurrence are avoided. The multi-functional puncture needle has the advantages of simple structure and convenient usage and is applicable for batch production and wide application.
