Background technology
In neurosurgery clinically, it is necessary to therapeutic agent is directly defeated via the conduit of implantation when especially doing surgical drainage
The specific objective of brain is sent to, current conduit has problems with：First, conduit excessively softness can not be positioned accurately；
Second, conduit is more crisp and easily causes fracture because of overbending；3rd, conduit fixed performance is poor, easily comes off；The
Four, when drainage-fluid is discharged, the problems such as easily causing medical worker and polluted by drainage-fluid, bring very big to the treatment of medical personnel
Inconvenience, the also potential very big danger for patient, these are all easily caused operative failure and easily injured brain tissue.In
State's number of patent application：201410276271.X discloses a kind of neurosurgical catheters device, and it solves lead to a certain extent
Pipe is excessively soft can not accurately to position problem that is more crisp with conduit and easily causing fracture because of overbending, but by
, still can there is asking for fracture in the one kind in first conduit uses titanium dioxide, nickel oxide or cobalt oxide ceramic material
Topic.Other drainage-fluid can not enter in drainage liquid container well.
The content of the invention
In order to solve existing above mentioned problem, the utility model provides a kind of neurosurgical catheters, by structure
Improvement, not only ensured the hardness of conduit but also taken into account conduit pliability, while drainage effect is more preferable.
The utility model solve its technical problem use technical scheme be：The conduit includes double-layer tube portion, drainage-fluid
Container, the first drainage tube, the second drainage tube, the double-layer tube portion, first drainage tube and second drainage tube difference
The drainage liquid container is connected, the double-layer tube portion includes inner catheter, outer catheter, between the inner catheter and the outer catheter
Reinforcer is provided with, is respectively equipped with first drainage tube and second drainage tube and is put catch, rotation is provided with the catch
Bull stick, the swingle stretches out discharge pipe.
The further technical scheme of the utility model is：The reinforcer of the reinforcer is to be uniformly arranged on the inner catheter
Some strip projected parts and the outer catheter between.
The further technical scheme of the utility model is：The strip projected parts connect the inner catheter and described outer lead respectively
Pipe, i.e. double-layer tube portion are an entirety.
The further technical scheme of the utility model is：Described reinforcer is to be uniformly arranged on the inner catheter and described
Some strip projected parts and annular projection between outer catheter.
The further technical scheme of the utility model is：The double-layer tube portion is one-shot forming.
The further technical scheme of the utility model is：The double-layer tube portion uses polyurethane, ethylene fluoride or poly- second
One kind in alkene.
The beneficial effects of the utility model are as follows：Double-layer tube portion and the setting of reinforcer, not only ensured conduit hardness but also
Take into account conduit pliability.The setting of two drainage tubes ensure that drainage-fluid can easily flow into drainage container.

Specific embodiment
To make the purpose of this utility model, technical scheme and advantage clearer, below will be to technology of the present utility model
Scheme is described in detail.Obviously, described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not before creative work is made
Resulting all other implementation method is put, the scope that the utility model is protected is belonged to.
A kind of neurosurgical catheters, as shown in Figure 1, including double-layer tube portion 1, drainage liquid container 2, the first drainage tube 3,
Second drainage tube 4, the double-layer tube portion 1, first drainage tube 3 and second drainage tube 4 connect the drainage respectively
Liquid container 2, the double-layer tube portion 1 includes inner catheter 8, outer catheter 7, is provided between the inner catheter 8 and the outer catheter 7 and added
Strong part 9, is respectively equipped with first drainage tube 3 and second drainage tube 4 and puts catch 5, and rotation is provided with the catch 5
Bar 6, the swingle 6 stretches out discharge pipe.
As shown in Figure 2, the reinforcer 9 of the reinforcer 9 is to be uniformly arranged on the inner catheter 8 and the outer catheter 7
Between some strip projected parts.The strip projected parts are connected on the inner catheter 8 and the outer catheter 7, i.e. double-layer tube portion 1
It is an entirety.Double-layer tube portion 1 and the setting of reinforcer 9, had not only ensured the hardness of conduit but also had taken into account conduit pliability.Conduit was both
Excessively softness can not will not accurately position, will not compare again crisp and easily cause to be broken because of overbending.
Described reinforcer 9 be uniformly arranged on some strip projected parts between the inner catheter 8 and the outer catheter 7 and
Annular projection.Compared to the strip projected parts being uniformly arranged, the hardness that strip projected parts and annular projection are combined conduit is bigger, fixed
Position is more convenient.
The double-layer tube portion 1 is one-shot forming.The double-layer tube portion 1 is using polyurethane, ethylene fluoride or polyethylene
In one kind.It is integrally formed, structural strength is stronger.
When using, when there is a small amount of drainage-fluid, the swingle 6 on the first drainage tube 3 need to be only turned with hand, make the first drainage
Pipe 3 is in closed state, and the second drainage tube 4 is in opening state (equivalent to blast pipe), and drainage-fluid is stored in drainage liquid container 2
It is interior；When drainage-fluid is more, the swingle 6 on the first drainage tube 3 is turned with hand, make the first drainage tube 3 in opening state, the
Two drainage tubes 4 are in closed state, and drainage-fluid enters in the drainage bag that pre- first drainage tube 3 is connected.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any one skilled in the art can readily occur in change in the technical scope that the utility model is disclosed
Or replace, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be with the power
The protection domain that profit is required is defined.
