AI Technical Summary
In robotic kidney transplantation, existing cryogenic ischemia storage bags can cause complications such as paralytic ileus obstruction due to the inflow of cryogenic fluid into the abdominal cavity. Furthermore, the storage bags are often too thin, which can lead to further problems.
A kidney storage bag was designed, comprising an insulating fabric, a medical pad, a drainage device, and a multi-layer structure. The drainage device is used to seal out the low-temperature fluid, and a large gauze is used to block the intestinal tract to prevent the fluid from flowing into the abdominal cavity. The bag is then fixed with medical thread.
This method enables the closed-loop extraction of cryogenic fluid within the tubing, avoiding complications such as paralytic ileus and improving surgical safety and efficacy.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to a kidney storage bag for use in robotic kidney transplantation surgery. Background Technology
[0002] Existing cryogenic ischemia storage bag technology can only drain about half of the influent volume of cryogenic fluid, with the remaining half flowing into the abdominal cavity between the intestines and around the abdominal organs. Secondly, the cryogenic storage bag is too thin, and if it is placed directly on the intestinal tract, there is a possibility of postoperative paralytic ileus. Utility Model Content
[0003] The purpose of this invention is as follows: All materials used in this invention are common surgical sterile consumables, which are low in cost, easy to manufacture, and have high application value. The cryogenic liquid is completely sealed within the tubing, so it will not flow into the abdominal cavity. A thick gauze barrier separates the storage bag from the intestinal tract, avoiding paralytic ileus complications caused by continuous cryogenic exposure. The technical solution is as follows:
[0004] A kidney storage bag for robotic kidney transplantation surgery, characterized in that: it comprises an insulating fabric 1 and several medical pads 2 evenly distributed horizontally along the upper and lower edges of the insulating fabric 1; medical pads 3 are symmetrically connected to the left and right edges of the upper surface of the insulating fabric 1; a drainage device 4 is inserted into the internal interlayer of the insulating fabric 1; an inlet connector 5 is connected to the center of one end of the drainage device 4; and a outlet connector 6 is connected to the center of the other end of the drainage device 4.

The drainage device 4 includes an infusion tube 4-1, a pad 4-2, and a rope 4-3. The pad 4-2 is provided below the side surface of the infusion tube 4-1, and the rope 4-3 is wrapped around the side surface of the infusion tube 4-1. The two ends of the rope 4-3 are sewn to the edge of the upper surface of the pad 4-2. The pad 4-2 is sewn to the inner surface of the sewn layer 1-4 and is U-shaped. One end of the infusion tube 4-1 is connected to the inlet connector 5, and the other end of the infusion tube 4-1 is connected to the outlet connector 6.

[0005] The advantages of this invention are: low cost, easy to manufacture, high application value, and the low-temperature liquid is completely sealed in the pipeline so that it will not flow into the abdominal cavity. There is a thick gauze barrier between the storage bag and the intestinal tract to avoid paralytic ileus complications caused by continuous low temperature. Attached Figure Description

[0009] Reference Figures 1-3 The kidney storage bag for robotic kidney transplantation surgery is characterized by comprising: an insulating fabric 1 and several medical pads 2 evenly distributed horizontally along the upper and lower edges of the insulating fabric 1; medical pads 3 symmetrically connected to the left and right edges of the upper surface of the insulating fabric 1; a drainage device 4 inserted into the internal interlayer of the insulating fabric 1; an inlet connector 5 connected to the center of one end of the drainage device 4; and a outlet connector 6 connected to the center of the other end of the drainage device 4; the insulating fabric 1 includes a gauze layer 1-1, an insulating layer 1-2, an absorbent layer 1-3, and a sewn layer 1-4; an insulating layer 1-2 inserted into the outer side of the folded gauze layer 1-1; an absorbent layer 1-3 located in the middle below the insulating layer 1-2; and a sewn layer 1-4 located in the middle below the absorbent layer 1-3; the insulating layer 1-2 is made of medical film material. The absorbent layer 1-3 is made of medical foam, and the sewn layer 1-4 is made of medical cotton cloth. The gauze layer 1-1, the insulation layer 1-2, the absorbent layer 1-3, and the sewn layer 1-4 are sewn together with medical thread. The drainage device 4 includes an infusion tube 4-1, a pad 4-2, and a rope 4-3. The pad 4-2 is provided below the side surface of the infusion tube 4-1, and the rope 4-3 is wrapped around the side surface of the infusion tube 4-1. The two ends of the rope 4-3 are sewn to the edge of the upper surface of the pad 4-2. The pad 4-2 is sewn to the inner surface of the sewn layer 1-4. The pad 4-2 is U-shaped and set on the inner surface of the sewn layer 1-4. One end of the infusion tube 4-1 is connected to the inlet connector 5, and the other end of the infusion tube 4-1 is connected to the outlet connector 6. The inlet connector 5 and the outlet connector 6 are each provided with a one-way valve to prevent backflow.
[0010] In use, the staff first places the pad 4-2 on the drainage device 4 in a U-shape on the insulation device 1. Then, the staff uses the string 4-3 to sew the infusion tube 4-1 and the pad 4-3 onto the sewn layer 1-4. Next, the staff uses medical thread to sew the opening of the gauze layer 1-1 through the medical pad 2. During sewing, the medical pad 2 prevents the gauze layer 1-1 from tearing open. Then, the donor kidney is placed on the upper surface of the inner gauze layer 1-1. Finally, the insulation device 1 is folded in half and the medical thread is used to sew the opening closed. The side opening is sutured with padding 3. At the same time, the aorta and vein of the donor kidney are extended out of the insulation device 1. Then, the feed connector 5 is connected to the 4℃ saline bag, and the discharge connector 6 is connected to the drainage bag. Then, the feed connector 5 and the discharge connector 6 are opened to inject 4℃ saline into the infusion tube 4-1 to provide constant temperature for the donor kidney. At the same time, the 4℃ saline is discharged into the drainage bag through the discharge connector 6. Finally, the staff places the insulation device 1 containing the donor kidney into the patient's abdominal cavity, and the robot can be used to perform the surgery.
[0011] When the insulation device 1 is placed in the patient's abdominal cavity, the 4°C saline solution is sealed out in the infusion tube 4-1 and protected by the insulation layer 1-2 so it will not flow into the abdominal cavity. Furthermore, the water formed by the temperature difference on the outer surface of the infusion tube 4-1 is drawn into the absorbent layer 1-3 through the absorbent layer 1-3 to prevent it from flowing into the patient's intestines, thus avoiding paralytic ileus complications caused by continuous low temperature.

Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
