Abstract
The invention provides a limited portal-caval shunt magnetic anastomosis ring. The anastomosis ring comprises two pairs of primary and secondary magnet groups, wherein the first primary and secondary magnet group consists of a first primary magnet and a first secondary magnet, while the second primary and secondary magnet group consists of a second primary magnet and a second secondary magnet; the first secondary magnet and the second secondary magnet are attracted, and shunt from portal vein to postcava can be completed by utilizing the two groups of magnets with corresponding sizes and shapes; by means of the magnetic anastomosis ring, the operation difficulty can be greatly reduced, the shunt port can be stable neither narrow nor expanded, the exact shunt effect can be guaranteed, and the occurrence of hepatic encephalopathy can be reduced; and a patient is only required to take anticoagulant drugs in a short period, so that the adverse influence caused by taking the anticoagulant drug for a long time to the body can be avoided.
Description
Technical field
The present invention relates to a kind of medical equipment, be specifically related to a kind of restricted portacaval shunt magnetic anastomosis ring.
Background technology
The main dependence of the operation of portacaval shunt at present is row portal vein and postcava side to side anastomosis by hand, or coincide by artificial blood vessel row " H " shape bridge-type between portal vein and postcava.The former is very high to the vascular anastomosis specification requirement, and its disadvantage is that the postoperative diffluence pass can become greatly, is prone to bring out hepatic encephalopathy clinically.The artificial blood vessel cost height that the latter is used, and very high to the vascular anastomosis specification requirement, and postoperative need be taken the anticoagulant medicine for a long time.These shortcomings have a strong impact on carrying out of portacaval shunt operation with difficulty.
Summary of the invention
In order to overcome the deficiency that above-mentioned prior art exists, the object of the present invention is to provide a kind of restricted portacaval shunt magnetic anastomosis ring, to have avoided adopting manual complicated operation process of coincideing, the postoperative diffluence pass can not become greatly, reduces the incidence rate of hepatic encephalopathy; Through using restricted portacaval shunt magnetic anastomosis ring, the patient only needs short-term to take the anticoagulant medicine, has avoided taking for a long time the negative effect that the anticoagulant medicine brings to body.
In order to achieve the above object, the technical scheme that the present invention adopted is:
A kind of restricted portacaval shunt magnetic anastomosis ring; Comprise two pairs of primary and secondary magnet groups; The first primary and secondary magnet group is made up of the first sub-magnet 1 and first female magnet 2, and the second primary and secondary magnet group is made up of the second sub-magnet 3 and second female magnet 4, and the first sub-magnet 1 is inhaled with the second sub-magnet 3 mutually.
Described first sub-magnet 1, second sub-magnet 3 sizes are identical, are oval-shaped annular magnet.
Described first female magnet 2, second female magnet 4 sizes are identical, are stair-stepping annular magnet, and the external diameter of stair-stepping jut is littler than the ring internal diameter of first sub-magnet 1, the second sub-magnet 3.
Advantage of the present invention is:
Through utilizing size and the corresponding two groups of magnets of shape; Accomplish portal vein to inferior caval shunting; Can reduce operating difficulty greatly by this magnetic anastomosis ring; And can guarantee that diffluence pass is stable, and neither can narrowly can not enlarge again, can guarantee that definite shunting effect reduces the incidence rate of hepatic encephalopathy simultaneously; Simultaneously, the patient only needs short-term to take the anticoagulant medicine, has avoided taking for a long time the negative effect that the anticoagulant medicine brings to body.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is done more detailed explanation.
A kind of restricted portacaval shunt magnetic anastomosis ring; Comprise two pairs of primary and secondary magnet groups; The first primary and secondary magnet group is made up of the first sub-magnet 1 and first female magnet 2, and the second primary and secondary magnet group is made up of the second sub-magnet 3 and second female magnet 4, and the first sub-magnet 1 is inhaled with the second sub-magnet 3 mutually.
Like Fig. 1, shown in Figure 3, described first sub-magnet 1, second sub-magnet 3 sizes are identical, are oval-shaped annular magnet.
Like Fig. 2, shown in Figure 4; Described first female magnet 2, second female magnet 4 sizes are identical; Be stair-stepping annular magnet; The external diameter of stair-stepping jut is littler than the ring internal diameter of first sub-magnet 1, the second sub-magnet 3, so that first sub-magnet 1, the second sub-magnet 3 can be nested into the stepped jut of first female magnet 2, second female magnet 4.
Operation principle of the present invention is:
As shown in Figure 5, postcava 5 and portal vein 6 before the art.
As shown in Figure 6, set up postcava otch 7 earlier, as shown in Figure 7, first female magnet 2 is presented in the postcava otch 7, then the first sub-magnet 1 is presented to outside the postcava otch 7, at this moment, the first sub-magnet 1 is inhaled as shown in Figure 8 with first female magnet 2 mutually.As shown in Figure 9, on portal vein 6, do portal vein otch 8.Shown in figure 10, in portal vein otch 8, insert second female magnet 4.Then the second sub-magnet 3 is presented to outside the portal vein otch 8, at this moment, the second sub-magnet 3 is inhaled shown in figure 11 with second female magnet 4 mutually.The first sub-magnet 1 is inhaled with the second sub-magnet 3 mutually, make postcava 5 and portal vein 6 each other near, and it is shown in figure 12 to form portacaval shunt road 9 through first sub-magnet 1, first female magnet 2, second sub-magnet 3, second female magnet, 4 intermediary holes.
Through utilizing size and the corresponding two groups of magnets of shape; Accomplish portal vein to inferior caval shunting; Can reduce operating difficulty greatly by this magnetic anastomosis ring; And can guarantee that diffluence pass is stable, and neither can narrowly can not enlarge again, can guarantee that definite shunting effect reduces the incidence rate of hepatic encephalopathy simultaneously; Simultaneously, the patient only needs short-term to take the anticoagulant medicine, has avoided taking for a long time the negative effect that the anticoagulant medicine brings to body.
