Specific embodiment
Below in conjunction with attached drawing, the preferred embodiment of the utility model is described in detail.
Such as Fig. 1~2, a kind of hepatobiliary drainage device convenient for rinsing dredging, including be sequentially linked together puncturing head 1, draw
Flow tube 2, negative pressure cavity bag 3, and worn from outside to inside into drainage tube 2 and being directed toward the flushing pipe 4 of puncturing head 1；The puncturing head 1
Petition warhead structure offers several conduction holes 5 thereon；The 2 inner wall circumferential direction of drainage tube offers internal chute 6；The interior cunning
Interior magnetic force sliding block 7 is equipped in slot 6；2 outer wall of drainage tube and 6 corresponding position of internal chute offer external chute 8；The outer cunning
Outer magnetic force sliding block 9 is equipped in slot 8；The outer magnetic force sliding block 9 matches connection with interior 7 magnetic force of magnetic force sliding block；The interior magnetic force sliding block
8 tops, which are connected with, scratches bar 10；The scratch bar 10 is in hook type structure, protrudes into 1 part of puncturing head and 1 inner wall of puncturing head
Fitting；The flushing pipe 4 is directed toward 1 one end of puncturing head and is equipped with anti-blocking mechanism, is located at 2 outside one end of drainage tube and is equipped with unidirectional fluid injection
Connector 11, and flushing pipe 4 is located at 2 exterior section of drainage tube generally in 8 lower section of external chute；The anti-blocking mechanism includes cover board
12, shaft 13, lower position block 14 and upper limit position block 15, such as Fig. 3, there are two be oppositely arranged and can be by flushing pipe 4 cover board 12
Upper end sealing, end are rotationally connected in flushing pipe 4 by shaft 13；14 lower end of lower position block is connected to flushing pipe
4 inner walls, lower surface when upper end is in close state with cover board 12 are bonded；15 lower end of upper limit position block is connected to flushing pipe 4
Inner wall is simultaneously located at 12 top of cover board, and medial surface is arranged in obtuse angle with 4 inner wall of flushing pipe.
In use, puncturing head 1 is placed in the bile duct of expansion by conventional medicine mode, bile is flowed by conduction hole 5
Drainage tube 2 finally flows into negative pressure cavity bag 3 and completes drainage.
After drainage time is longer, 2 front end of drainage tube sticky hydrops easy to form will lead to conduction hole 5 and front end
Drainage tube 2 blocks.It keeps stablizing at this point, holding drainage tube 2 on the other hand, rotates outer magnetic force sliding block 9 on the other hand, make it around 8 turns of external chute
It is dynamic.Because outer magnetic force sliding block 9 cooperates with interior 7 magnetic force of magnetic force sliding block, therefore interior magnetic force sliding block 7 also rotates under drive around internal chute 6,
To which the inner wall for driving the scratch bar 10 that connect with interior magnetic force sliding block 7 to be bonded puncturing head 1 rotates, to be blocked in conduction hole 5 with
And the sticky bile hydrops on the drainage tube 2 of front end is scratched.At the same time, physiology salt is injected by unidirectional fluid injection connector 11
The flushing liquors such as water, via flushing pipe 4 spray, with scratch bar 10 formed cooperate, rinsed while scraping, realize targetedly and
Efficiency explicitly dredges operation.The above operation can also be carried out periodically, it is not necessary to be waited to plug and just be dredged.
When not rinsing dredging, direction 1 one end of puncturing head of flushing pipe 4, can be anti-to avoid bile because being equipped with anti-blocking mechanism
It is blocked to flushing pipe is flowed into, specific implementation is shown in Fig. 3, and when not in use, two cover boards 12 are closed flushing pipe 4,
It is made in lower position block 14 simultaneously, so that cover board 12 is kept closed state, prevents it excessively to 4 internal bend of flushing pipe.When
When using flushing pipe 4, flushing liquid washes cover board 12 open by hydraulic naturally, but the most multipotency of cover board 12 is opened to 15 inside of upper limit position block
Face, 15 medial surface of upper limit position block are arranged in obtuse angle with 4 inner wall of flushing pipe, also can avoid the excessive opening of cover board 12.
Further, the present embodiment further includes the air bag 16 that 1 rear of puncturing head is arranged in；The air bag 16 and a tracheae
It is pierced by after 17 conductings by drainage tube 2, the one end being pierced by is equipped with gas-charging connection 18, and to be located at 2 exterior section of drainage tube whole for tracheae 17
Body is in 8 lower section of external chute, interferes when 8 inner circumferential of external chute is slided with tracheae 17 to avoid outer magnetic force sliding block 9；Its unaerated
When flushed with 1 surface of puncturing head or it is slightly concave fall into, in the disc structure of prominent puncturing head 1, such as Fig. 4 after inflation.It can be by filling
Gas connector 18 is inflated to air bag 16, is scraped and is affixed in bile duct after bloating air bag 16, prevents puncturing head 1 from accidentally being pulled out bile duct.It can also
To be evacuated by gas-charging connection 18, restores shrivelled state after so that air bag 16 is excluded gas, finally taken out puncturing head 1 with facilitating.
Further, the anti-blocking mechanism that the present embodiment uses further includes the bullet between cover board 12 and lower position block 14
Spring 19；19 both ends of spring are connected to 12 lower surface of 4 inner wall of flushing pipe and cover board, such as Fig. 3, and spring 19 can rinse
Pipe 4 when not in use, cover board 12 is pulled down to and is contacted with lower position block 14, and cover board 12 is kept to be in close state.
Further, the interior magnetic force sliding block 7 and outer magnetic force sliding block 9 that the present embodiment uses are made of ndfeb magnet, are
Strong magnets can adsorb 640 times of weight of weight itself, it is more compared to ferrite lattice, alnico, the magnetism of SmCo
Significantly, more can guarantee interior magnetic force sliding block 7 and outer magnetic force sliding block 9 across drainage tube 2 also can good magnetic connection do not fall off.
Further, the width for the external chute 8 that the present embodiment uses is greater than the width of internal chute 6, and corresponding outer magnetic force is sliding
The width of block 9 is greater than the width of interior magnetic force sliding block 7.Because rotation scratch movement is dominated by outer magnetic force sliding block 9, interior magnetic force sliding block 7
It is also located at and needs to guarantee that it does not fall off in drainage tube 2, structure design then more can ensure that interior magnetic force sliding block 7 can be sufficiently and complete
It is adsorbed by outer magnetic force sliding block 9.
Further, being connected on the outside of the outer magnetic force sliding block 9 that the present embodiment uses facilitates the handle of rotation process (not show in figure
Out).
Finally, it is stated that preferred embodiment above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, to the greatest extent
Pipe has been described in detail the utility model by above preferred embodiment, but those skilled in the art should manage
Solution, can make various changes, without departing from the utility model claims book institute to it in the form and details
The range of restriction.
