Claims

1. A rat liver transplant blood vessel anastomosis cannula with an anti- coagulation coating, comprising an outer tube (1), an inner tube (2) and an anti- coagulation coating (3), characterized in that: The outer tube (1) is connected to the inner tube (2) at one end, and both the outer tube (1) and the inner tube (2) are provided with an anticoagulant coating (3); The outer tube (1) is provided with an outward-turned tube (101) at one end near the inner tube (2), and the outward-turned tube (101) is provided with a threaded sleeve (102) at one end near the inner tube (2). The outward-turned tube (101) is provided with multiple sets of spring expansion sleeves (103) and secretion holes (104). The outer tube (1) is provided with multiple sets of U-shaped limiting holes (105) near the inner tube (2). The inner tube (2) has multiple sets of threaded protrusion rings (201) near the threaded sleeve (102) on the outside. The inner tube (2) has a plug tube (202) near the outer tube (1) and multiple sets of through holes (203) on the plug tube (202).

2. The rat liver transplant vascular anastomosis cannula with an anti- coagulant coating according to claim 1, characterized in that: When the outer tube (1) and the inner tube (2) are aligned, the U-shaped limiting hole (105) and the through hole (203) are distributed in a corresponding manner inside and outside.

3. The rat liver transplant vascular anastomosis cannula with an anti- coagulant coating according to claim 1, characterized in that: The threaded sleeve (102) at one end of the outward-facing tube (101) and the multiple sets of threaded protruding rings (201) on the outside of the inner tube (2) are connected by a sleeve.

4. The rat liver transplant vascular anastomosis cannula with an anti- coagulant coating of claim 1, wherein: Multiple sets of spring expansion sleeves (103) and secretion holes (104) are distributed in a ring at equal intervals on the everted tube (101).

5. The rat liver transplant vascular anastomosis cannula with an anti- coagulant coating of claim 1, wherein: After the outer tube (1) and the inner tube (2) are matched, the insertion tube (202) is inserted between the outer tube (1) and the outward-facing tube (101).

6. The rat liver transplant vascular anastomosis cannula with an anti- coagulant coating of claim 1, wherein: The anticoagulant coating (3) is made of a material selected from heparin or a polymer.
