Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples, and embodiments of the present invention include but is not limited to
The following example.
Embodiment 1
As shown in Figure 1, a kind of unidirectional valve formula stent drainage system, including by polylactic acid radical biological degradable shape memory
Bracket and unidirectional valve made of material；The bracket original state in hollow cylinder 1 and is set to hollow cylinder two by middle part
End is with the central axial outer radial barrier rib 2 of hollow cylinder；The unidirectional valve is located in hollow cylinder.
Wherein, the unidirectional valve is one end and the hinged movable plate 3 of hollow cylinder inner wall；The other end of the movable plate
It is also connected with traction rope 4.
Specifically, the movable plate is connected with hollow cylinder inner wall by pin shaft 5, and is used in hollow cylinder inner wall equipped with position
The barrier plate 6 rotated to side is only capable of in limitation movable plate.Above-mentioned barrier plate is specifically located at beside pin shaft, can be avoided in this way
Movable plate is rotated to the other side, to realize the effect unidirectionally opened.
If having hydrops in patient's lumen, when needing to exclude, it can be drained into gastral cavity and be operated by above-mentioned apparatus,
It is while to lumen open, device one end of the present embodiment then to be entered into opening in gastral cavity sidewall opening and reaches lumen first
Interior, the other end stays in gastral cavity, to make lumen be connected to gastral cavity, to be drained.Specifically, the bracket of the present embodiment uses
Polylactic acid radical biological degradable shape-memory material keeps the structure such as Fig. 1 in the initial state；However it is carrying out being implanted to people
It is to be heated and softened first to it in vivo, is then conformed into Fig. 2 structure, is then cooled down, dress above-mentioned in this way
Fig. 2 shape and structure can all be kept by setting, and also be equivalent to be a tubulose, at this moment just can be respectively protruding into tube body both ends corresponding
Two chambers in, then since temperature raises, the bracket of the present embodiment will gradually be deformed into original state, and barrier rib just can
Enough stop supports are slipped out of chamber influences drainage effect, to successfully be drained；Additionally, due to be provided with unidirectional valve,
Also it is equivalent to be check valve, can be realized one-way flow, avoid gastric acid and carry out in other chambers, it is ensured that drainage process
Safety.In addition, the present embodiment is provided with traction rope, when needing to carry out liquid medicine injection or other liquid from gastral cavity to other chambers,
Movable plate can be lifted, by pulling traction rope so that just injecting fluid can be carried out from gastral cavity to other chambers.Operation ten
Divide simple.
As a preference, being connected with soluble wire between the traction rope and movable plate.By the way that soluble wire is arranged, performing the operation
After, soluble wire can be absorbed molten short, at this time can easily take out traction rope, and bracket and unidirectional valve are by gathering
Made of lactyl Biodegradable shape-memory material, so can also be explained in vivo, taking-up is thus eliminated
The operation of bracket, to greatly reduce patient suffering.It is made in addition, the traction rope can also be adopted of degradation material, this
Sample can also be absorbed completely, then do not have to further take out, to reduce surgical procedure, improve efficiency.
Embodiment 2
As shown in figure 3, the present embodiment the difference from embodiment 1 is that, it is remote that the barrier plate of the present embodiment is set to movable plate
One end from pin shaft is equivalent in this way from bottom and carries out the rotation of barrier activity plate, while can achieve the function unidirectionally opened
Can, then the barrier plate is only a fritter, as long as can barrier activity plate to the side rotate.
Embodiment 3
As shown in figure 4, the present embodiment the difference from embodiment 1 is that, the traction rope is equipped with far from one end of movable plate
Portable part 10.It is very convenient when pulling traction rope by the way that portable part is arranged, and be not in sense of discomfort.
Embodiment 4
As shown in figure 5, the present embodiment is the difference from embodiment 1 is that unidirectional valve is different, the unidirectional valve of the present embodiment
Including the partition 7 being axially arranged along hollow cylinder, which will be divided into two chambers in hollow cylinder；One end of the partition
Equipped with for controlling the first opening/closing check valve of one of chamber；The other end is equipped with opening/closing for controlling another chamber
Second one-way valve.
Specifically, first check valve is identical with second one-way valve, and includes one end and the hinged work of hollow cylinder
Movable plate 8, and be set on hollow cylinder inner wall and be only capable of the stopper 9 rotated to side for limiting movable plate.
Hollow cylinder is separated into two chambers by partition, and control flowing is carried out by the different check valve of both direction
Direction is flowed into gastral cavity in this way when being drained by one of valve, when an injection is needed, then can be by another
A valve will be in liquid injection to other chambers.It is easy to operate, and drawn without traction rope；It is above-mentioned simultaneously
Component is made of polylactic acid radical biological degradable shape-memory material, oneself can degrade after the completion of operation, without removing branch
Frame gives patient's bring pain so as to avoid removing.
Embodiment 5
As shown in fig. 6, the present embodiment and the difference of embodiment 4 are, first check valve is identical with second one-way valve,
And include one end and the hinged activity template 8 of partition, and be set on hollow cylinder inner wall for limit movable plate be only capable of to
The stopper 9 of side rotation.The present embodiment is different from the fixed movable plate of embodiment 4 and the setting position of stopper, passes through setting
Position is different, can equally reach corresponding unidirectional unlatching effect, so that the present invention can carry out reality in several ways
It is existing.
According to above-described embodiment, the present invention can be realized well.It is worth noting that before based on said structure design
It puts, to solve same technical problem, even if that makes in the present invention is some without substantive change or polishing, is used
Technical solution essence still as the present invention, therefore it should also be as within the scope of the present invention.
