Further, in detachable subdural space conductor provided by the invention, such feature can also be had: the dual-side of the first semi arch housing is respectively equipped with along axially extended first slide rail of the first semi arch housing and the first chute; The dual-side of the second semi arch housing is respectively equipped with along axially extended second slide rail of the second semi arch housing and the second chute; First slide rail is engaged mutually with the second chute, and the first chute is engaged mutually with the second slide rail.
Further, in detachable subdural space conductor provided by the invention, can also have such feature: the far-end of plug has clinoplain and arcwall face, the far-end of the first semi arch housing has the chamfered inside wall fitted with clinoplain.
Further, in detachable subdural space conductor provided by the invention, such feature can also be had: the afterbody of the first semi arch housing and the second semi arch housing is equipped with handle.
Further, in detachable subdural space conductor provided by the invention, such feature can also be had: handle is the dull and stereotyped handle perpendicular to guide thimble.
Further, in detachable subdural space conductor provided by the invention, such feature can also be had: handle has anti-skidding matte surface.
Further, in detachable subdural space conductor provided by the invention, such feature can also be had: the near-end of plug is provided with the cylinder be integrally formed; The diameter of cylinder is greater than the interior caliber of guide thimble.
Further, in detachable subdural space conductor provided by the invention, such feature can also be had: the interior caliber of guide thimble is 5 millimeters.
The good effect that the present invention has on the basis of the above is:
Detachable subdural space conductor provided by the invention, like a cork shadow stream pipe can be positioned over subdural space, it is specially: drainage tube is when encountering the chamfered inside wall of far-end of the first semi arch housing, can turn voluntarily and enter subdural space like clockwork, to subdural space hydrops or hemorrhagely to aspirate, drain, this detachable subdural space conductor is not only convenient to drain, and be convenient to fix, while reaching efficient drainage treatment, also injured brain tissue can be avoided, significantly reduce the wound of performing the operation and patient being caused, accelerate the post-operative recovery of patient.
In addition, formed because guide thimble to be engaged with the second semi arch housing mutually by the first semi arch housing, after the diseased region that such structure facilitates mozzle to implant in subdural space, make detachable subdural space conductor be easy to disassemble from drainage tube, facilitate doctor to implement operative treatment to intracranial lesion.

Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reach object and effect is easy to understand, following examples are specifically addressed detachable subdural space conductor provided by the invention by reference to the accompanying drawings.
As shown in Figure 1, the detachable subdural space conductor that the present embodiment provides is for inserting subdural space by drainage tube, and it has bullet shaped revolving body.Bullet shaped revolving body comprises: plug 1 is sleeved on guide thimble 2 on plug with axial.
Guide thimble 2 to be mutually engaged with the second semi arch housing 22 by the first semi arch housing 21 and to be formed.And the Yuan Duan ﹑ of Yuan Duan ﹑ plug 1 of the first semi arch housing 21 and the far-end of the second semi arch housing 22 form the warhead section of bullet shaped revolving body jointly.The diameter of plug 1 is greater than the diameter of drainage tube, and the equal diameters of the interior caliber of guide thimble 2 and plug 1, in the present embodiment, the interior caliber of guide thimble 2 is 5 millimeters.
