Continuous refrigeration system for kidney transplantation operation

Abstract

The invention relates to the technical field of medical instruments, in particular to a continuous refrigeration system for kidney transplantation operation, which is used for refrigerating kidney from the beginning of kidney transplantation operation to the opening of artery and vein of the kidney and comprises a kidney bag, an in-vitro ring and an in-vivo ring, a bag opening is formed in one end of the kidney bag, the kidney and crushed ice enter the kidney bag through the bag opening, the in-vitro ring and the in-vivo ring are arranged on the kidney bag at intervals, and leading-out ends are arranged on the outer side and the inner side of the bottom of the kidney bag. The local length of the kidney bag is supported to form the through circulation channel, the kidney enters the kidney bag through the circulation channel so as to obtain a carrier entering a human body, operation is easy, convenient and rapid, the kidney bag can adapt to laparoscopic surgery due to the arrangement of the leading-out end, and by pulling the leading-out end on the outer side of the bottom of the kidney bag, the kidney can be conveniently pulled to the kidney anastomosis position, the kidney bag can be pulled out of the body by pulling the leading-out end on the inner side of the bottom of the kidney bag after operation, and it is guaranteed that the kidney is in a continuous low-temperature environment by adding crushed ice to the bag opening for multiple times.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a continuous refrigeration system for kidney transplant operations. Background technique [0002] At present, kidney transplantation, especially laparoscopic or robot-assisted laparoscopic kidney transplantation has the advantages of less trauma compared with open surgery, and it is beneficial to patients' wound healing in the later stage, and has become the mainstream trend of kidney transplantation. However, in the current technology, due to the small opening of the surgical approach under the microscope, there is no access channel and surgical operation channel for the kidney to pass through, and it is difficult to ensure that the kidney is kept in a low temperature environment before and during the operation. The survival rate of the renal organ after surgery is affected. [0003] In view of the existence of the above problems, based on the rich practical experience ...

Problems solved by technology

However, in the current technology, due to the small opening of the surgical approach under the microscope, there is no designed access channel and surgical operation channel for the kidney to pass through, and it is difficult to ensure that the kidney is kept in a low temperature environment before and during the operation. Survival rate of renal organs after surgery has an impact
