Problems solved by technology

[0003] During the operation, the guidance of the catheter is completely achieved by the doctor using special techniques outside the body. Therefore, the experience and skills of the surgeon are the key to the success of the operation. If the operation is not performed properly, the vascular lumen of the relevant path will be damaged, and even the operation will fail.
In addition, the materials used in the operation process are all disposable, and the treatment process is generally not completed through one operation, so the operation cost remains high

Abstract

The invention discloses an in-vitro guiding type phlebothrombosis dredging machine which comprises a rotor knife and an external magnetic field device. The rotor knife comprises a shell body, a knife head, a direct-current motor, a control circuit board, two permanent magnets, a density adjusting bag, thrombolytic agents, an air inflation pipe and a sealing plug. The external magnetic field device comprises two electromagnet groups. Each electromagnet group comprises an upper electromagnet, a lower electromagnet, a left electromagnet and a right electromagnet. The invention further provides a working method of the in-vitro guiding type phlebothrombosis dredging machine. Guidance is carried out on the rotor knife through an external magnetic field, and operation difficulty and cost are lowered.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a device for removing obstruction in a blood vessel. Background technique [0002] Endovascular minimally invasive treatment of venous thrombosis minimally invasive surgery is a medical technique in which the surgeon inserts a catheter through the main venous vessel to the lesion and performs surgery in the vascular cavity with the assistance of vascular imaging equipment, anesthesia and other technologies. Due to the complexity of the vascular path, the process of inserting the catheter to the lesion is a key link in the operation. [0003] During the operation, the guidance of the catheter is completely achieved by the doctor using special techniques outside the body. Therefore, the experience and skills of the surgeon are the key to the success of the operation. If the operation is not performed properly, the vascular lumen of the relevant path will be damaged, and even the operation w...
