Temperature-controlled organ cooling jacket system for open and robotic-assisted surgeries

Cold ischemia plays a crucial role in open and robotic-assisted kidney transplants and partial nephrectomy surgeries, not only minimizing the risk of renal injuries but also extending the duration of the operation. Traditionally, the cooling process relies on the application of ice slush to the donor kidney during operation, a method prone to variability as the amount of ice slush is determined arbitrarily by the operating doctor. To address this issue, a novel approach is proposed, introducing a temperature-controlled organ cooling jacket. This innovative design incorporates auxiliary liquid circulation and refrigeration units, providing a controlled and consistent cooling environment. The cooling jacket, crafted from biocompatible materials through negative molding with 3D printed molds, represents a significant departure from the temperature-uncontrolled procedures prevalent in current practices. The development of the device is detailed in this study, covering the entire process from design conception to manufacturing techniques. The materials and methods employed in the production of the organ cooling jacket are discussed, highlighting the adherence to design constraints. The efficiency of the device is examined through ex vivo testing, shedding light on the promising results achieved. This comprehensive exploration encompasses the evolution of the proposed solution, offering valuable insights into its potential application in enhancing and implementing temperature-controlled cold ischemia in open and robotic-assisted kidney surgeries.
