EMBODIMENTS

[0012] The technical proposal for the invention is clearly and completely described below in combination with the drawings. Obviously, the described embodiments are only part of the embodiments of the invention, but not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by ordinary technicians in the field without creative labor are within the scope of protection of the invention.

[0013] In the description of the invention, it should be noted that the orientation or position relations are indicated by the terms such as “center” and “upper” and “lower,” “left” and “right,” “vertical” and “horizontal,” “inner” and “outer” are based on the orientation or position relations shown in the drawings for the convenience of describing the invention and simplifying the description, but do not indicate or imply that the device or component must be constructed and operated in a particular orientation, so they shall not be construed as a limitation on the invention. In addition, the terms “first”, “second,” and “third” are used for descriptive purposes only and are not construed to indicate or imply a relative importance. The invention is further described in detail in combination with the drawings.

[0014] As shown in FIG. 1, an in vivo organ transfer device provided by the invention comprises an organ fixing bag 1 and an organ bag push assembly 2, the organ fixing bag 1 is composed of an inner bag 3 and an outer bag 4, the outer bag 4 is provided with an ice water filling hole 5 and link rod fixing interfaces 6, multiple groups of link rod fixing interfaces 6 are arranged on both sides of the outer bag 4, the inner layer bag 3 is provided with an organ inlet 7, an input conduit opening 8 and an output conduit opening 9, the organ bag push assembly 2 comprises fixing rods 10 and bayonets 11, the fixing rod 10 is the same as the in vitro part of the ordinary minimally invasive grasper, and the bayonet 11 is arranged at the end of the fixing rod 10 and fits with the link rod fixing interfaces 6.

[0015] For specific use, the organ is put into the inner bag 3 through the organ inlet 7 outside the body, the inflow tube is led through the input conduit opening 8, the outflow tube is led through the output conduit opening 9, the fixing rods 10 are connected to the left and right sides of the organ fixing bag 1 through the link rod fixing interfaces 6 and the bayonet 11 after vacuuming between the inner bag 3 and the outer bag 4 through the ice water filling hole 5, the organ is delivered into the body from the incision, the organ fixing bag 1 is delivered to the predetermined position through the left and right fixing rods 10, fine-adjusted, and then fixed so that the organ conduits led from the input conduit opening 8 and the output conduit opening 9 keep the optimal anastomosis distance and angle with the conduits butted inside the body, ice water is quickly filled between the inner bag 3 and the outer bag 4 through the valve at the ice water, filling hole 5 to cover the organ, the built-in thermometer displays the real-time temperature between the inner bag 3 and the outer bag 4, and the ice water around the organ is kept at 0 to 4° C. During vascular remodeling, it can be changed constantly through the valve at the ice water filling hole 5.

[0016] After vascular remodeling and before restoration of perfused blood flow, the ice water is quickly changed to hot water to open the anastomotic stoma and rewarm the liver, the organ fixing bag 1 can be sheared inside the body to release the organ after stable circulation, all bleeding during release is anastomotic bleeding, the organ position can be adjusted through the fixing rods 10 on two sides to reveal the bleeding points for suture hemostasis, the organ is released when the anastomotic stoma does not bleed, and then the small area of blood oozing is examined on the organ surface, thus achieving the effect of step-by-step hemostasis and improving the hemostasis precision and efficiency in the minimally invasive surgery.

[0017] The invention and its embodiments are described above. The description is not restricted, the drawings only show one of the embodiments of the invention, but the actual structure is not so limited. In a word, if the ordinary technicians in the field are inspired by the invention, design structures, and embodiments similar to the technical proposal without deviation from the purpose of the invention and without creativity, such structures and embodiments shall be within the scope of protection of the invention.
