Abstract

The invention discloses a reciprocating type thrombus plaque cutting device and belongs to the technical field of medical appliances. The reciprocating type thrombus plaque cutting device comprises asheath tube, a power output link, a sucking chamber and a handle, wherein the sheath tube is fixedly connected to the top end of the sucking chamber; the power output link penetrates through the sheath tube and a U-shaped chamber and can move back and forth in the sheath tube; a liquid flow chamber is formed between the sheath tube and the power output link and communicates with the U-shaped chamber through a connecting flow passage; a cam mechanism is arranged in the U-shaped chamber and drives a U-shaped link to reciprocate in the U-shaped chamber; and a cutter head is fixedly connected intoa gap between the top end of the power output link and the sheath tube. According to the reciprocating type thrombus plaque cutting device, the cutter head is internally installed and cannot injure periphery blood vessels, and sucking in the U-shaped chamber is of indirect work, so that blood loss of a sufferer during surgical operation is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a reciprocating thrombus plaque removal device. Background technique [0002] Intravascular thrombotic plaque lesions include thrombus, embolism, atherosclerotic plaque, etc. Percutaneous endovascular resection to remove lesions has less trauma and shorter hospital stay, and is widely adopted. Commonly used interventional devices for percutaneous endovascular resection include SilverHawk resection system, Jetstream high-pressure water injection system, Rotarex rotary cutting system, Diamond grinding system, etc. The cutting efficiency of the SilverHawk resection system is high, but the cutting debris enters the tubular shell and collects, which cannot be removed immediately, which may easily cause distal embolism. The Jetstream high-pressure water injection system is suitable for fresh blood clots and does not damage blood vessels, but excessive blood loss is prone to oc...
