It is furthermore preferred that every group of ring-type connector separately includes the equal cyclic annular connector of 2-3 diameter of section.
Further, the second end outer openings are in cusp-shaped, angle shape or smooth blunt mouth shape.
Multipath blood vessel connector described in the utility model can be made of flexible or rigid material, preferably medical PVC, PC, PP etc.
Material.
Multipath blood vessel connector described in the utility model can be applied in organ perfusion, organ transfer operation；It specifically makes
With method are as follows: the second end of the multipath blood vessel connector is inserted into blood vessel, it is closely cyclic annular according to vessel diameter selection fitting
Connector is ligatured as ligation fixed point.
The utility model has an advantage that compared with prior art
1) the utility model blood vessel connector is designed using a variety of outer diameters, vessel diameter different problems is considered, according to blood vessel
Internal diameter selects connector outer diameter, and the single diameter connector scope of application is wider than in the prior art, and connector is not easy to take off after fixing with blood vessel
It falls, ensure that the safety and stability of operation；
2) the utility model blood vessel connector includes the cyclic annular connector of multiple groups different cross section diameter, compared with the prior art middle tool
There is the taper variable diameter blood vessel connector of smooth outer wall to be easier to fixed ligation, ligation effect is more preferable, and stability is stronger in surgical procedure.
3) using simply, connector and vascular ligation are fixed conveniently, securely the utility model blood vessel joining operations.
