The invention provides an
artery plaque intracavitary directional rotary
cutting device and a using method thereof, and belongs to the technical field of
medical instruments. The arterial plaque intracavitary directional rotary
cutting device comprises a
tool bit protection sleeve, a
medicine storage part, a
windmill type rotary
cutting tool bit, a hollow spiral-line-shaped long-strip net bag structure recycling net, a
metal supporting net, a guide
pipe and a
control unit. On the basis of having the advantages of a plaque excision device in the prior art, the
artery plaque intracavity directional rotary cutting device further has the following advantages that (1) the rotary cutting position is accurate; (2) the
medicine is suitable for treating patients with femoral popliteal
lesion and below-knee
arteriosclerosis obliterans; (3) the operation cost and the operation risk are low; (4) the stimulation and trauma to a patient are small in an operation; (5) the rotary cutting depth is long; (6) the
cut plaques and chippings can be prevented from falling off; (7) the
restenosis progress of blood vessels can be delayed, and
inflammatory response and immune response caused by operations can be relieved; and (8) the device is easy to clean after operation.
