The invention discloses a special-shaped probe multi-point refrigerating
system for bronchoscope
cryopreservation, and relates to the technical field of
medical instruments, the special-shaped probe multi-point refrigerating
system mainly comprises a probe, an air
pressure sensing execution sleeve and a
wireless computer control system, the special-shaped probe on the probe is provided with four dome cylindrical protruding parts, the middle of the special-shaped probe is sunken, and five capillary tubes are arranged in the probe; the five point
refrigeration areas correspond to the convex part and the concave part of the special-shaped probe respectively, so that the five point
refrigeration areas are independent; an initial pressure value required by
pressure reduction and heat absorption of high-pressure gas is calculated, a
wireless signal is transmitted by a
computer control system, and then the five air
pressure sensing execution sleeves release corresponding pressure, so that the temperature of different point positions on the special-shaped probe is different. Meanwhile, the provided multi-point
refrigeration system achieves independent adjustment of the temperatures of different point positions in the probe, prevents the probe from touching and
frostbite surrounding healthy tissues by mistake, and has a good clinical application prospect.
