Description

Laser ablation device for arteriosclerosis occlusion Technical Field The utility model relates to the technical field of medical appliances, in particular to a laser ablation device for arteriosclerosis obliteration. Background The external Zhou Xin cerebral arteriosclerosis obliteration ASO refers to chronic progressive diseases which are caused by arteriosclerosis, such as thickening of blood supply arterial intima of lower limbs, lumen stenosis or obliteration, insufficient blood supply of diseased limbs, intermittent claudication of lower limbs, pain, ulcer or necrosis and other clinical manifestations, and is usually the manifestation of systemic arteriosclerosis vascular lesions in the arterial of lower limbs. On the distribution of ASO affected arteries, the affected proportion of the main iliac arteries is about 30% and 80% of lesions can affect superficial femoral arteries SFA. The affected proportion of the popliteal artery is as high as 80% -90%. The lesion proportion of the tibiofibular artery is 40% -50%. Because the symptoms of ASO are often not obvious, the condition is easily missed and missed, most patients have progressed to chronic total occlusion lesions CTO at the time of visit, with severe limb ischemia CLI and gangrene. Traditional treatment methods include stent implantation, balloon expansion and the like, but the methods may have the problems of high recurrence rate, damage to blood vessels and the like. Disclosure of utility model The utility model provides a laser ablation device for arteriosclerosis obliteration, which solves the problems in the prior art. The object of the utility model is achieved by a laser ablation device for arteriosclerotic occlusion comprising: the terminal of the joint part is provided with a socket for installation and a first fiber channel is arranged in the joint part in a penetrating way; The adjusting part comprises a piston cylinder body, a piston and a hollow threaded rod, a rotating mechanism is arranged on one side, close to the joint part, of the piston cylinder body, the hollow threaded rod is arranged in the piston cylinder body in a sliding mode and is in threaded connection with the rotating mechanism, and the tail end of the hollow threaded rod is provided with the piston and a second optical fiber channel; The ablation portion comprises a catheter sheath, a guide wire channel, a physiological saline channel and a third optical fiber channel, wherein the guide wire channel, the physiological saline channel and the third optical fiber channel are arranged on the catheter sheath, a balloon is arranged at the tail end of the physiological saline channel, and the third optical fiber channel is communicated with the second optical fiber channel and the first optical fiber channel in sequence. Further improvement, the sacculus includes with the first cavity that physiological saline passageway is linked together and with the second cavity that first cavity is linked together, the cross-section of second cavity is the arc. Further improvement, the second cavity is provided with two groups, and the two groups of second cavities are symmetrically arranged on two sides of the first cavity. Further improvement, the piston cylinder body adopts transparent material and the outside is provided with the scale.
