For solving the problems of the technologies described above, the technical scheme that this utility model adopts is: a kind of double-rail anesthesia associating trocar is provided, comprise needle stand and the first needle body, described needle stand is communicated with the first needle body, offer in described the first needle body and can intert the first pin hole of anesthetic tube, described needle stand one side is provided with the side seat, and described the first needle body one side is fixed with the second needle body, offer in described the second needle body and can intert the second pin hole of lumbar puncture needle, described the second pin hole is communicated with the side seat.
In preferred embodiment of this utility model, described side seat and needle stand are one-body molded.
In preferred embodiment of this utility model, the top end face tilt of described side seat arranges.
In preferred embodiment of this utility model, the diameter of described the second needle body is less than the diameter of the first needle body.
In preferred embodiment of this utility model, the length of described the second needle body is less than the length of the first needle body.
In preferred embodiment of this utility model, described the second needle body and the first needle body are bonding.
In preferred embodiment of this utility model, the liquid outlet of described the second needle body is side cut opening.
In preferred embodiment of this utility model, be fixed with two installing plates on described needle stand, described installing plate is symmetrical arranged.
In preferred embodiment of this utility model, described installing plate is fixed in the groove of needle stand.
In preferred embodiment of this utility model, the needle tip of described the first needle body is provided with and makes the pin mouth to the curved bend pars convoluta of lopsidedness.
the beneficial effects of the utility model are: this utility model double-rail anesthesia associating trocar has a side seat due to one-body molded on needle stand, anesthetic tube enters human body by needle stand along the first needle body, lumbar puncture needle can enter human body along the second needle body simultaneously by the side seat, adopt the double-rail structure effectively to avoid anesthetic tube and lumbar puncture needle to enter simultaneously the same area, cause different injection medicinal liquids mutually to mix, precision is high, improved transfusion speed, safe and reliable, and this double-rail anesthesia associating trocar is simple in structure, easy to make, operator can facilitate, accurately, realize rapidly operation.
Description of drawings
Fig. 1 is the perspective view of this utility model double-rail anesthesia associating trocar one preferred embodiment;
