The outer surface of the sliding rod is slidably connected to the inner wall of the sliding groove, which plays a role in supporting the microcatheter body 3, so that the microcatheter body 3 can remain stable during adjustment.
[0027] Among them, an anti-slip cover is fixedly installed on the outer surface of the handle 2. The anti-slip cover is made of rubber material. Its purpose is to prevent the handle 2 from slipping, so that medical staff will not fall off when using it, which makes it safer.
[0028] It should be noted that when medical staff use the easily-steerable cerebrovascular intervention microcatheter, they do not need to insert the mounting frame 1 , but only need to adjust the microcatheter body 3 to a suitable length before use.
[0029] Specifically, by providing an adjustment mechanism, the direction and length of the microcatheter body 3 can be adjusted, so that the microcatheter body 3 is more convenient to use, and the microcatheter body 3 can be adjusted according to the patient's condition, thereby increasing the use range of the microcatheter body 3.
[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the adjustment mechanism includes a connecting column 601 rotatably mounted on the left side wall of the inner cavity of the adjustment groove 5 and one end of which penetrates and extends to the outside thereof, an electric push rod 602 is fixedly mounted on the right side of the connecting column 601, a driven gear 603 is fixedly mounted on the outer surface of the connecting column 601, a support rod 604 is rotatably mounted between the left and right side walls of the inner cavity of the adjustment groove 5, a driving gear 605 is fixedly mounted on the outer surface of the support rod 604, the outer surface of the driving gear 605 is meshed with the outer surface of the driven gear 603, and a worm gear 606 is fixedly mounted on the outer surface of the support rod 604. A fixing groove 607 is provided on the inner top wall of the adjusting groove 5, and a micromotor 608 is fixedly installed on the inner top wall of the fixing groove 607. The output shaft of the micromotor 608 is fixedly installed with a fixing column 609 through a coupling. The output end of the micromotor 608 faces downward, and a worm 610 is fixedly installed on the bottom of the fixing column 609. The outer surface of the worm wheel 606 is meshed with the outer surface of the worm 610. A limit plate 611 is fixedly installed on the outer surface of the connecting column 601. An electric telescopic rod 612 is fixedly installed on the inner bottom wall of the adjusting groove 5, and a clamping rod 613 is fixedly installed on the top of the electric telescopic rod 612.
[0031] The right side of the electric push rod 602 is fixedly connected to the left side of the micro-catheter body 3 , so that the electric push rod 602 can drive the micro-catheter body 3 to move, thereby adjusting the length of the micro-catheter body 3 .
[0032] The limiting plate 611 is located on the left side of the driven gear 603 and on the right side of the worm gear 606 , so that the limiting plate 611 will not affect the movement of the driven gear 603 and the worm gear 606 when rotating, thereby adjusting the microcatheter body 3 .
[0033] Among them, a through hole is opened on the right side wall of the inner cavity of the adjustment groove 5. The size of the through hole is adapted to the size of the connecting column 601, which plays a role in supporting the connecting column 601, making the connecting column 601 more stable when in use.
[0034] It should be added that the micromotor 608 is miniature and will not cause the microcatheter body 3 to vibrate during operation, thereby not causing harm to the patient during adjustment.
[0035] Among them, a sliding rod is fixedly installed on the top of the microcatheter body 3, and a sliding groove is opened on the inner wall of the mounting frame 1. The outer surface of the sliding rod is slidably connected to the inner wall of the sliding groove. The width of the sliding groove is larger than the width of the sliding rod. When it works, it can support the microcatheter body 3, and the microcatheter body 3 will not shake when it rotates.
[0036] Among them, the outer surface of the limit plate 611 is provided with a plurality of evenly distributed limit grooves, and the sizes of the plurality of limit grooves are adapted to the size of the clamping rod 613, thereby achieving the purpose of limiting the microcatheter body 3, so that the microcatheter body 3 can be fixed after adjustment, thereby improving the stability of the microcatheter body 3.
[0037] The electrical components in the present invention are all electrically connected to an external main controller, and the main controller can be a conventional known device for controlling a computer, etc. The circuits and controls involved in the present invention are all prior art and will not be elaborated on here.

By setting up the limit plate 611, the electric telescopic rod 612, and the clamping rod 613, the purpose is to limit the microcatheter body 3 so that the microcatheter body 3 can be fixed after adjustment, so that the microcatheter body 3 can work stably.
[0039] The working principle of the above embodiment is:
[0040] When the length and direction of the micro-catheter body 3 need to be adjusted, the length is adjusted first, and the electric push rod 602 is started first, so that the electric push rod 602 drives the micro-catheter body 3 to move to the right. When the length of the micro-catheter body 3 moving out of the mounting frame 1 is suitable for the patient, the electric push rod 602 is closed, and then the micro-motor 608 is started, so that the micro-motor 608 drives the fixed column 609 to rotate, the fixed column 609 drives the worm 610 to rotate, the worm 610 drives the worm wheel 606 to rotate, the worm wheel 606 drives the support rod 604 to rotate, the support rod 604 drives the driving gear 605 to rotate, so that the driving gear 605 drives the driven gear 605 to rotate. The gear 603 rotates, and the driven gear 603 drives the connecting column 601 to rotate, so that the connecting column 601 drives the electric push rod 602 to rotate, and the electric push rod 602 drives the microcatheter body 3 to rotate, and the microcatheter body 3 drives the slide bar to rotate in the slide groove, and the microcatheter body 3 drives the treatment component 4 to rotate. When the treatment component 4 rotates to a suitable position, the micromotor 608 is turned off, and the electric telescopic rod 612 is started at this time, so that the electric telescopic rod 612 drives the clamping rod 613 to move upward, so that the clamping rod 613 is clamped with the corresponding limit groove on the limit plate 611, and the steering and length adjustment of the microcatheter body 3 are completed.
