Joint trocar, including：Needle stand and needle body, the section of the needle body are rounded, and the needle body is internally provided with caudal anaesthesia and leads
Pipe tube chamber and lumbar anaesthesia puncture needle tube chamber, are formed with corresponding anesthetic tube import and lumbar anaesthesia puncture needle import, institute on the needle stand
State segmental epidural catheter tube chamber, lumbar anaesthesia puncture needle tube chamber to be set with the excircle eccentricity of needle body, the lower end of the needle body has
One conical puncturing head, the inside of the conical puncturing head offers a court and is bent away from lumbar anaesthesia puncture needle tube chamber direction
Arc endoporus, the matching of the arc endoporus and segmental epidural catheter tube chamber connect, and the arc endoporus is from cone puncture
Passed on the side of head, a vertical endoporus communicated with lumbar anaesthesia puncture needle tube chamber be further opened with the conical puncturing head,
The vertical endoporus is passed from the side of conical puncturing head.
In one preferred embodiment of the utility model, the base area of the conical puncturing head and the section face of needle body
Product is identical.
In one preferred embodiment of the utility model, the conical puncturing head is monolithic construction with needle body.
The beneficial effects of the utility model are：The utility model double rail type anaesthetizes joint trocar, simple and reasonable, can
Anesthetic tube is efficiently separated with lumbar anaesthesia puncture needle, also there is splendid puncture resistance in addition.
Brief description of the drawings
