[0002] Neurointerventional devices refer to a series of medical consumables used for the diagnosis and treatment of cerebrovascular diseases around neurointerventional procedures. Neurointerventional devices are currently mainly used in the diagnosis and treatment of cerebrovascular diseases. When performing neurosurgery, thrombus aspiration technology is generally used. The specific technology is: inserting a catheter into the blood vessel, using a special instrument to extract the thrombus in the blood vessel where the thrombus has formed to restore blood flow. When producing and processing the neurointervention catheter, the neurointervention catheter needs to be coated.
[0003] The existing Chinese patent application with application publication number CN113634436A discloses a polytetrafluoroethylene coating device for medical catheter guidewires, comprising a box body and a cabinet door rotatably mounted on the box body, wherein a partition is fixedly mounted in the cabinet door, and the partition divides the box body into an upper chamber and a lower chamber, and a coating coating mechanism is fixedly mounted on the bottom inner wall of the lower chamber, and the coating coating mechanism comprises a solution pool, wherein a baffle is fixedly mounted in the solution pool, and the baffle divides the solution pool into a first solution tank and a second solution tank, and a wire collection mechanism and a curing mechanism are fixedly mounted in the upper chamber; the invention can perform a fast and efficient secondary coating operation on the catheter guidewire, and can select the number of catheter guidewires to be coated as needed, has the advantages of fast speed, and a high degree of integration, and does not require excessive human involvement.
[0004] However, the coating application equipment has the following defects when used specifically: 1. When coating catheters for neurointervention, existing coating equipment generally uses ultrasonic coating to improve the efficiency and effect of coating the catheters. However, when coating the catheters by ultrasonic coating, the coating material will remain on the surface of the catheter, affecting the adhesion and quality of the coating. At the same time, when coating the catheters, a large number of tiny bubbles and dirt particles will be generated, affecting the smoothness and quality of the neurointervention catheters. 2.

[0038] In the neurointervention catheter coating equipment of the present invention, when the neurointervention catheter is coated with a coating, the cylinder clamp 807 can clamp and fix the two ends of the neurointervention catheter. Afterwards, when the coating operation is performed, the high-speed motor 806 is started to operate, driving the neurointervention catheter to rotate at a high speed, and realizing the coating operation of the neurointervention catheter. The deflection plate 805 can be rotated by the operation of the rotating motor 804, which is convenient for driving the clamped neurointervention catheter to rotate. When the neurointervention catheter moves to the top, the coating operation is performed. When the neurointervention catheter moves to the bottom, it is located inside the cleaning liquid, and the neurointervention catheter after the coating operation is completed is cleaned. When the neurointervention catheter is in a horizontal position, the neurointervention catheter can be conveniently installed and disassembled. The hydraulic cylinder 801 can drive the T-shaped plate 802 and the neurointervention catheter to move up and down, which is convenient for adjusting the position and height of the neurointervention catheter.
