The invention provides a
balloon endoscopic
system for intravascular
direct vision examination, and relates to the technical field of
medical instruments, the
balloon endoscopic
system comprises a
catheter, a
balloon capable of being filled and discharged, an
endoscope lens, a
light source assembly and an image transmission
processing module, a cavity channel used for containing the
endoscope lens and a conduction component of the
light source assembly is formed in a
catheter body of the
catheter, and the catheter body of the catheter is internally provided with a cavity channel used for containing the
endoscope lens and the conduction component of the
light source assembly; the filling pipeline is used for supplying liquid to the
inflatable and deflatable balloon; the
inflatable and deflatable balloon is fixedly connected to the outer surface of the front end of the catheter, and the
inflatable and deflatable balloon is used for bulging after being conveyed to a target position in a
blood vessel. The inflatable and deflatable balloon can block
blood flow and open the
blood vessel wall after bulging and is matched with transparent filling liquid injected into the filling pipeline, residual blood can be further removed, a blood-free observation window is formed, interference of blood on imaging is avoided, and a foundation is laid for clearly observing the condition of the
blood vessel wall. The inner wall of the balloon is coated with a nano anti-
fog coating, so that the penetrability of a light source is ensured, and the
fogging surface influence caused by blood residue or
temperature difference can be avoided.
