Technical Field
The utility model relates to the technical field of medical appliances, in particular to a thrombolysis catheter with a controllable injection range.
Background
Thrombus is composed mainly of insoluble fibrin, deposited platelets, accumulated leukocytes and entrapped erythrocytes. When blood flows through the thrombus, the local pressure of the blood vessel is increased, and the thrombus is seriously blocked even if the thrombus is caused, thus endangering the life of a patient.
There are three methods for treating thrombus, which are more commonly used clinically at present, the first is an artificial mechanical method, and the thrombus in the blood vessel is taken out through a surgical operation or a suction device. The second is to move to the stent to enlarge the vessel lumen. Thirdly, thrombolytic drug therapy is adopted, and thrombus is gradually dissolved by injecting thrombolytic drug so as to achieve the purpose of vascular conduction.
Thrombolytic drug therapy generally needs to use a thrombolytic catheter, most of the existing thrombolytic catheters adopt a single-cavity structure, a plurality of side holes are cut on the wall of a perfusion section of the catheter by laser, and drugs in the lumen are sprayed into thrombus through the side holes, so that thrombolysis is realized. Such thrombolytic catheters have the following problems: for the condition of more thrombus in the blood vessel, because the gaps among the thrombus can be filled with blood, after the cannula is inserted, the catheter blocks the gaps which are originally filled with blood, so that the illness state is aggravated, and even life danger is brought to the patient.
The patent name of the publication number CN208287326U is: thrombolytic catheters. This publication solves the above-mentioned problems, but the disadvantage in the publication device is that: because the sizes of thrombolysis range areas of each patient are different, the overall length of the side holes distributed from top to bottom of the device of the publication is fixed, the length cannot be changed according to the length change of the lesion thrombus of the patient, when the length of the lesion thrombus of the patient is smaller than the overall length of the side holes in the device of the publication, at the moment, sprayed liquid medicine can be absorbed by the tissues with intact peripheries of the lesion sites of the patient, damage is caused to the tissues with intact peripheries of the lesion sites of the patient, the whole liquid medicine cannot fully contact with the lesion sites of the patient, and the treatment effect of the liquid medicine is reduced.
