Further, the inner side of the second needle handle is provided with an injector interface.
Further, the diameter of the first needle shaft is larger than the diameter of the syringe interface.
Furthermore, an anti-slip structure is arranged on the outer side of the first needle handle.
Further, the anti-slip structure is knurled.
Furthermore, the lower end of the needle body is blunt.
Furthermore, the lower end of the needle body is sharp.
Furthermore, the needle body and the needle sleeve are both made of stainless steel.
The embodiment of the utility model provides a have following advantage:
the embodiment of the utility model provides a clearance to between needle body and the needle cover is adjusted after experimental many times, and with the clearance design between needle cover and the needle cover for 0.1 ~ 0.2mm, the needle body closely cooperates with the needle cover, guarantees the circulation of air simultaneously, makes the needle body not only can not oneself glide under the action of gravity but also insert the needle easily, ensures going on smoothly of operation.
The product is suitable for brain tissues, and is used for percutaneous puncture under the guidance of ultrasound and CT, thereby providing a new method for the treatment of intracranial lesions. Through clinical practice, the operation is more convenient and faster, and the use is safer and more effective.

Detailed Description
The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. In the present specification, the terms "upper", "lower", "left", "right", "middle", and the like are used for the sake of clarity only, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof are also considered to be the scope of the present invention without substantial changes in the technical content.
Referring to fig. 1-4, this brain is with pjncture needle includes needle body 1 and needle cover 3, and 1 upper end of needle body is equipped with first needle handle 2, and 3 upper ends of needle covers are equipped with second needle handle 4, and 1 covers of needle body are established at needle cover 3 inboards, is equipped with 0.1 ~ 0.2 mm's clearance between needle body 1 and the needle cover 3, and this clearance circulation of air makes needle body 1 not only can not oneself glide under the action of gravity but also advance the needle easily, ensures accurate needle of advancing.
For convenient operation, this embodiment is equipped with anti-skidding structure in first needle handle 2 outside, and is concrete, this anti-skidding structure is the annular knurl. The needle body 1 and the needle sleeve 3 in the embodiment are both made of stainless steel materials, and can adapt to the sterilization environment of hospitals.
