Abstract

The invention discloses a minimally invasive thrombus removing device for cardiovascular surgery, and belongs to the field of medical instruments. The minimally invasive thrombus removing device for the cardiovascular surgery comprises an expansion section, athrombus eliminating section, a main screw, an extension pipe and a conical head; a rotary connector is fixedly installed at the left end of the main screw; the conical head is screwed and installed at the left end of the rotary connector through a screw thread; the extension pipe is installed on the right portion of the outer side of the main screw in a sleeving mode; and the expansion section is screwed and installed at the left end of the extension pipe and the left end of the conical head through a screw thread. The minimally invasive thrombus removing device for the cardiovascular surgery is reasonable in structural design; partition thrombolysis can be carried out; thrombi are prevented from being left in blood vessels; and theminimally invasive thrombus removing device for the cardiovascular surgery is matched with micro-motion mechanical thrombus scraping and drug thrombolysis, adopts continuous flushing so as to avoid residues caused by incomplete flushing, is more efficient in thrombolysis, is small in action range and slight in range after the structure is unfolded, avoids damage to the blood vessels, and is safer and very high in practicability.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a minimally invasive blood vessel embolism removal device for cardiovascular surgery. Background technique [0002] Medical devices refer to instruments, equipment, utensils, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are used directly or indirectly on the human body for the purpose of diagnosis, prevention, monitoring, treatment or alleviation of diseases, cardiovascular embolism Surgery is to remove blood clots or debris on the inner wall of blood vessels to ensure the smooth flow of blood vessels. [0003] After searching, the Chinese patent authorization number is CN110801266A patent, which discloses a blood vessel dredging device and a blood vessel dredging cleaner. In use of the above-mentioned patent, the blockage on the inner wall of the blood vessel is wiped down by the plug that rotates and expands, which has a certain...
