Description
Technical field
The invention belongs to technical field of medical instruments, refer to especially a kind of medical portal hypertension part flow arrangement.
Background technology
Later period of hepatocarcinoma patient is most can be with hepatocirrhosis symptoms.In cirrhosis, liver function, lose the compensatory phase and often show as portal hypertension: i.e. esophagus, Therapy for Gastric Variceal massive hemorrhage, intractable ascites pleural fluid repeatedly, seriously jeopardizes patient's life.
At present, the common method for the treatment of above-mentioned portal hypertension is the mode that adopts TIPS intervene operation, its method is: adopt seal wire, microcatheter technology, in liver, between portal vein and hepatic vein, insert metal rack, set up a split channel, to reduce pylic pressure, thereby prevent and reduce the probability of a series of complication such as digestive tract hemorrhage that caused by portal hypertension.
But TIPS intervene operation is the technology of the most difficult in periphery intervention and risk maximum, reason is will be in liver before inserting metal rack, will to liver cirrhosis region, puncture with puncture needle between portal vein and vein, forms path and could further put into support and set up expansion path after puncture.In this process, first, puncture needle will enter in body by conduit, and from jugular vein to hepatic portal vein, path in vivo can be through atrium, and in art, danger is high; Secondly, because patient's degree of cirrhosis is generally all very high, the operation puncturing time is generally all very long, causes the whole operation process also can be very long; Moreover a whole set of operation need to be used a large amount of medical apparatus and instruments, surgery cost is high, and a general operation gets off to spend ten thousand yuan of 3-4.Because difficulty, the risk and cost of TIPS intervene operation are all larger, so the hospital that can carry out at home this technology seldom.
Summary of the invention
The object of the present invention is to provide a kind of medical portal hypertension part flow arrangement.
Technical scheme of the present invention is:
A portal hypertension part flow arrangement, it mainly consists of diverter and conduit and pipe joint element, it is characterized in that: described diverter, is comprised of collet, upper cover, silicagel pad; Wherein,
Described collet is a circular configuration, is provided with the boss of hollow in it; Boss wall is provided with 2 guide holes; In the bottom of collet, be provided with several fixing holes;
Top at boss is provided with upper cover; On be covered with mesopore;
Described silicagel pad is to consist of the large round platform of the little round platform in top and bottom; And little round platform can embed in the mesopore of upper cover; The little round platform of silicagel pad is to embed the mesopore of upper cover from the bottom of upper cover; The lower edge part of the large round platform of silicagel pad, higher than guide hole, forms an empty chamber in boss;
Guide hole Joint in one end of described pipe joint element and diverter; The other end of pipe joint element is connected with conduit.
In one end of conduit, be provided with several side openings, to prevent from forming thrombosis.
Described conduit or pipe joint element, can adopt metal tube or medical macromolecular materials.
Described conduit or pipe joint element diameter are to determine according to required shunt volume, and the size of conduit or pipe joint element diameter and shunt volume is proportional.
The invention has the advantages that: the present invention has reduced the risk of operation: complicated TIPS is got involved to maneuver, become the skin puncture technology of simple possible; Shortened operating time: due to the step of having avoided liver cirrhosis position to puncture, therefore simplified operating procedure, shortened the time in art; Make patient save surgery cost: it is only achievable operation with a small amount of apparatus that a large amount of apparatuses of use are changed into, therefore saved patient's quality cost, has alleviated patient burden.

The specific embodiment
Below just in conjunction with Figure of description and embodiment, the invention will be further described.
As shown in Figure 1,2,3, 4, portal hypertension part flow arrangement of the present invention, it mainly by diverter 1 and conduit 2,2 ' and pipe joint element 22,22 ' form.Described diverter 1, is comprised of collet 11, upper cover 12, silicagel pad 13; Wherein,
Described collet 11 is a circular configuration, is provided with the boss 14 of hollow in it; Boss 14 walls are provided with 2 guide holes 15,15 '; In the bottom of collet 11, be provided with 4 fixing holes 16;
On the top of boss 14, be provided with upper cover 12; Upper cover 12 is provided with mesopore 17;
Described silicagel pad 13 is to consist of the large round platform 19 of top roundlet platform 18 and bottom; And roundlet platform 18 can embed in the mesopore 17 of upper cover 12; The roundlet platform 18 of silicagel pad 13 is to embed the mesopore 17 of upper cover 12 from the bottom of upper cover 12; The lower edge part of the large round platform 19 of silicagel pad 13 is higher than guide hole 15, in empty chamber 20 of the interior formation of boss 14;
Described pipe joint element 22, one end of 22 ' respectively with diverter 1 in guide hole 15,15 ' Joint; Pipe joint element 22,22 ' the other end are connected with conduit 2,2 ' respectively; In conduit 2, one end of 2 ', be provided with several side openings 21,21 '.
Described conduit 2,2 ' or pipe joint element 22,22 ', adopts metal tube.
When application portal hypertension part flow arrangement of the present invention is treated operation, can be different according to the pressure at the difference of patient's hepatocirrhosis symptoms and portal vein place, and need to select the conduit 2,2 ' in the portal hypertension part flow arrangement of different technologies parameter, shunt.
According to the parameter of patient's self Portal Blood Flow and portal vein internal diameter, select the size of conduit 2,2 ' diameter.Conduit 2,2 ' diameter carry out calculative determination according to the size of required shunt volume.Known: Portal Blood Flow: L
0=800～900ml/min;
Portal vein pressure: P=12～24cmHg;
Portal vein internal diameter: d
0=10.7mm;
Portal Blood flow velocity: V0=0.145m/s;
Suppose: blood flow speed V1=V0=0.145m/s in diverter;
:
it is required conduit diameter
(1), shunting L
1during=200ml blood, need conduit diameter:
d
1＝(200/800)×10.7mm＝2.7mm；
(2), shunting L
1during=300ml blood, need conduit diameter:
d
1＝(300/800)×10.7mm＝4mm；
(3), shunting L
1during=400ml blood, need conduit diameter:
d
1＝(400/800)×10.7mm＝5.35mm；
Under portal hypertension: diverter internal pressure P2 > P=12～24cmHg;
Blood flow speed V2 > V0=0.145m/s in diverter;
:
it is required conduit diameter
(1), shunting L
2during=200ml blood, need conduit diameter:
d
2＜(200/800)×10.7mm＝2.7mm；
(2), shunting L
2during=300ml blood, need conduit diameter:
d
2＜(300/800)×10.7mm＝4mm；
(3), shunting L
2during=400ml blood, need conduit diameter:
d
2＜(400/800)×10.7mm＝5.35mm。
Known patient's condition: Portal Blood Flow is 800-900ml/min, portal vein internal diameter is 10.7mm, according to required shunt volume, calculates acquired results, shown in list 1:
[table 1]
| Embodiment | Shunt volume (ml) | Conduit diameter (mm) |
| |
100 | 1.34 |
| |
200 | 2.68 |
| Embodiment 3 | 300 | 4.00 |
| Embodiment 4 | 400 | 5.35 |
| Embodiment 5 | 500 | 6.69 |
| Embodiment 6 | 600 | 8.02 |
| |
700 | 9.36 |
| Embodiment 8 | 800 | 10.70 |
According to the above results, can find out, the size of conduit 2,2 ' diameter and shunt volume is proportional.In conjunction with actual shunt volume analysis, can preferred embodiment 2,3,4 be most preferred embodiment, conduit 2,2 ' diameter be best in scope between 2.68mm-5.35mm.
The present invention is when carrying out portal hypertension shunt operation in application, first at vein and portal vein, carries out percutaneous puncture respectively; And be detained respectively puncture conduit 2,2 ', then respectively two root puncture conduits 2,2 ' the other end be connected on portal hypertension diverter 1; Thereby form an external path, finally portal hypertension diverter 1 is fixedly inserted subcutaneous, operation complete.Visible, apply portal hypertension part flow arrangement of the present invention, can abandon traditional method of making in vivo path, and become, form in vitro path, realize the technology of shunting, it has not only alleviated patient's misery, has also alleviated patient's burden.
