Embodiment Construction

[0040] The mechanical thrombus removal device proposed by the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0041] The definitions of "proximal" and "distal" in this article are: "distal" generally refers to the end of the medical device that first enters the patient's body during normal operation, and "proximal" generally refers to the end of the medical device that enters the patient's body during normal operation. The end of the process that is closest to the operator.

[0042] Please refer to figure 1 , which is a schematic structural view of the mechanical thrombus...

Abstract

A mechanical thrombus remover is provided. A thrombus suction system in the mechanical thrombus remover includes a suction device and a thrombus suction tube, wherein the suction system based on the structure provides the negative pressure in a manner different from the existing high-speed rotational siphon-forming manner based on the helical structure in that the negative pressure is provided ina manner different from the conventional suction system, negative pressure required by thrombus suction can be formed without high-speed rotation , thus effectively reducing the existing helical structure to form negative pressure process rotational speed is too fast to cause the temperature is too high and lead to the problem of guide wire fracture. In addition, the thrombus suction system and the thrombus crushing system of the invention are two mutually independent systems, and the mutual influence of the thrombus suction and the thrombus crushing process is effectively avoided.The procedure of thrombolysis is carried out in the thrombectomy head, which effectively reduced the probability of complications of hematuria and renal failure and the incidence of vascular perforation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a mechanical thrombus removal device. Background technique [0002] Deep venous thrombosis (DVT) of the lower extremities is a disease caused by abnormal coagulation of blood in the deep veins of the lower extremities. DVT leads to increased venous pressure, obstruction of blood return, lower extremity swelling, pain, and dysfunction. At the same time, there is a risk of thrombus dislodgment, and the thrombus dislodges with the impact of blood flow to the pulmonary artery, which can cause pulmonary embolism (PE). If DVT is not effectively treated in the acute phase, thrombus organization, venous obstruction, loss of valve function, venous reflux and venous hypertension will form post thrombosis syndrome (PTS), endangering the survival of limbs and life. [0003] By taking orally or injecting aspirin, heparin or warfarin, the drug can enter the blood system, effectively d...
