Description
Technical Field
The invention relates to the technical field of intravascular thrombus aspiration pumps, in particular to a thrombus aspiration pump capable of rapidly replacing consumable materials and a use method thereof.
Background
Thrombosis is a clinically common disease. The main hazard of thrombus is 1) the thrombus blocks the vessel lumen, causing the remote blood backflow to be blocked; 2) The thrombus is shed, so that serious harm such as pulmonary embolism, cerebral embolism, myocardial ridge embolism and the like is caused. Thrombus aspiration is a method in which a catheter is sent to a thrombus site under negative pressure to directly suck thrombus into the catheter and remove the thrombus. The advantage of catheter intervention methods for thrombus aspiration is (1) minimally invasive. The high-risk embolic patient is critical in illness, the traditional open operation is difficult to endure, and relatively speaking, the interventional therapy finishes the suction operation of the catheter under the local anesthesia, so that the wound is small and the recovery is quick; (2) rapid availability.
Current development of thrombus aspiration technology focuses on several aspects:
1. suction catheter and Integrated System-suction catheter integrated System comprising a guide catheter or balloon catheter, delivery catheter and suction catheter, suction pump, thrombus plaque collector and Thrombus plaque debris device (US 2019/0216476A 1-Penumber Inc.)
2. The suction catheter is provided with a suction channel and a flushing channel, the control box is connected with the two channels of the catheter to complete suction and flushing under synchronous control (US 10944944B2-Boston Scientific Scimed Inc; US9332999B 2-Covin LP); thereby preventing the aspiration path from being plugged and requiring the aspiration of the catheter to clear the thrombus plaque and reinsertion of the catheter.
3. A strain gauge or differential pressure sensor is placed on the aspiration catheter and the controller calculates the flow from the differential pressure to monitor whether the aspiration catheter tip is in contact with the clot. If there is no contact, the suction is stopped by automatically closing the on-off valve in the suction connection pipe. If the catheter is blocked, pulse suction is activated (US 6022747-Bayer CO; US 16/977431-Penumber Inc).
The chinese patent publication No. CN113289092a discloses a pumping apparatus and pumping method synchronized with pulse, comprising: a suction pump, a suction pipeline and a pulse detection device; the pulse detection device is electrically connected with a controller of the suction pump, and the suction pump sucks through the suction pipeline; the suction pump provides a pulsed pressure; the controller adjusts the pulse pressure according to the pulse signal detected by the pulse detection device, so that the pulse starting time of the pulse pressure and the contraction pressure of the pulse are kept synchronous within a preset time error range.
