The invention discloses a removing device, and relates to the technical field of
medical instruments. The removing device comprises a conveying guide
pipe, a push-pull piece and a remover. The conveying
catheter is provided with a first cavity channel and a second cavity channel, and the first cavity channel is used for the guide wire to pass through; the push-pull piece is movably arranged in the second cavity channel at least in the axial direction of the conveying
catheter; the remover and the far end of the push-pull part are connected or integrally formed, the remover is used for scraping away a fibrous
protein sheath on the outer surface of the
central venous catheter, and the push-pull part is used for controlling the remover to be switched between a storage position and an unfolding position and adjusting the size of the remover; at the storage position, the cleaner is folded in the second cavity; in the deployed position, the
scavenger is open and located outside the delivery
catheter. The invention provides a removing device which is used for removing fibrous
protein sheaths on the surface of a
central venous catheter, the
central venous catheter does not need to be frequently replaced, the treatment cost is lower, the pain of a patient is reduced, and
pulmonary embolism caused by the fact that the fibrous
protein sheaths enter pulmonary arteries is avoided.
