Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, completeDescribe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based onEmbodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premiseEmbodiment, broadly falls into the scope of protection of the invention.
Referring to Fig. 1～3, in the embodiment of the present invention, a kind of magnesium alloy can absorb blood vessel anastomat, including female seat 1 and public affairsSeat 2, wherein a lateral edges of male seat 2 arranges card, and a lateral edges of female seat 1 arranges bayonet socket, and male seat 2 and female seat 1 are by cardFixing with bayonet fittings and be connected, it is achieved quickly dock, described male seat 2 all offers mutually corresponding through hole with the middle part of female seat 1,So that blood vessel fracture passes fixing from through hole.
Being respectively provided with identical pin 4 and pin hole 5 on described male seat 2 and the contact surface of female seat 1, the pin 4 that coincide is used for fixing blood vessel, kissClosing pin 4 with pin hole 5 around the evenly spaced distribution of through hole, the pin 4 that coincide is corresponding with the diameter of pin hole 5.
When described male seat 2 is connected with female seat 1, male seat 2 coordinates grafting with the identical pin 4 in female seat 1 with pin hole 5, to ensureLocation, ensures that the fracture of two blood vessels is crimped together closely simultaneously.
The material of described male seat 2, female seat 1 and identical pin 4 is magnesium alloy, and magnesium alloy can be slow under environment in body fluidDegraded, the degradable time is 8-12 week, the trace element of the magnesium ion internal existence of behaviour that degraded discharges；In degradation processIn, it is allowed to the progressively reparation of blood vessel wall, reduces the anastomotic stoma complication risk such as thrombosis, anastomotic leakage blood.
Described magnesium alloy can absorb the operational approach of blood vessel anastomat:
(1) the blood vessel fracture connected is needed to be each passed through the through hole in the middle part of male seat 2 and female seat 1, then by blood vessel fracture by twoBlood vessel wall after turning up and turning up is fixed on identical pin 4；
