Description

Technical Field

[0001] The utility model relates to the technical field of cerebral artery thrombectomy, in particular to a cerebral artery thrombectomy suction pump. Background Art

[0002] Cerebral artery thrombosis refers to abnormal solid, liquid, or gaseous objects (called emboli) that enter the cerebral artery system through the blood circulation, causing occlusion of the arterial lumen. During embolectomy surgery, negative pressure suction is usually required to remove the thrombus.

[0003] Publication No. CN212326511U discloses a handheld thrombus negative pressure suction pump, which can directly observe the change of negative pressure through a negative pressure gauge; and the pressure regulating valve can automatically release pressure and manually release pressure, so that the operation can be stopped in time; the negative pressure suction pump of the utility model realizes the requirements of low cost, simple and labor-saving operation, accurate negative pressure suction effect, and intuitive pressure change;

[0004] However, the above-mentioned negative pressure suction pump for cerebral artery thrombectomy still has the following problems during actual use: a negative pressure is formed inside the tube through a connecting rod inside the stent to suction the thrombus, but when using it, it is always necessary to hold the stent in hand to drive the connecting rod to form a negative pressure inside the tube. The overall negative pressure value is difficult to stabilize and maintain a constant pressure, which leads to deviations in the suction pressure. At the same time, this type of operation method will also reduce the efficiency and convenience of thrombectomy, thereby affecting the work of cerebral artery thrombectomy.

[0005] Therefore, we propose a cerebral artery thrombectomy and suction pump to solve the above-mentioned problems. Utility Model Content
