Abstract
Cooling systems are described herein that may be used in connection with one or more attached devices to cool patient tissue. The disclosed cooling systems include a refrigeration unit containing a thermoelectric element in thermal communication with a heat exchanger, a fluid pump in fluid communication with a fluid inlet and a fluid outlet, tubing connecting the fluid inlet to the fluid outlet, a fluid cooling element in thermal contact with the thermoelectric element, and a temperature sensor positioned to detect a temperature of fluid within the tubing. The temperature of fluid within the tubing can be controlled by a control unit having a user interface and a power controller to adjust cooling power to the thermoelectric element. Various types of devices can be configured to receive and circulate cooled fluid from the cooling systems, such as retractor blades, retractor shims, cooling pads, and scope sheaths.
