Abstract

The invention relates to the technical field of medical instruments, and particularly discloses a thrombus interceptor which comprises a supporting bag and a communicating pipe, the supporting bag is provided with a placement hole and a plurality of circulation holes, the diameter of the circulation holes is smaller than the minimum section of thrombus, the circulation holes are used for blood to flow through, the placement hole is used for containing a catheter, and the supporting bag can abut against the inner wall of a blood vessel after bulging; the connecting pipe is communicated with the supporting bag, the connecting pipe can be externally connected with a machine so that the supporting bag can be swelled or shrunken, and the supporting bag can be filled with a contrast agent. According to the scheme, the thrombolysis catheter is matched with the interceptor for use, so that integration of a thrombolysis function, a thrombus extraction function and a thrombus interception function can be realized by virtue of an ultrasonic technology; the problem that thrombus is intercepted through a metal filter screen in the prior art is solved, and a thrombus patient can be treated and cured in time even in the field and other sites with poor medical conditions.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a thrombus interceptor. Background technique

[0002] In existing medicine, there are many cases of thrombosis in blood vessels, including arterial thrombosis and venous thrombosis. For common limb arteriovenous thrombosis, surgery for thrombectomy is more traumatic to patients and there are many postoperative complications. Therefore, in clinical practice, the method of radiological intervention is generally used. For veins, the method of thrombectomy can be used, or the method of thrombolysis can be used. Whether it is thrombectomy or thrombolysis, the catheter needs to be inserted into the blood vessel, and then the catheter can be used. Aspirate the thrombus or use a catheter to inject drugs to dissolve the thrombus. However, whether it is thrombolysis or thrombectomy, in the process, there is a probability that the thrombus will fall off the blood vessel wall and mov...
