During the operation, one doctor usually uses his hand to aim the ultrasound probe at the lesion site, while another doctor performs the operation. For longer operations, the arms of medical staff holding the ultrasound probe are prone to fatigue, and auxiliary devices are needed to support the arms to reduce the difficulty of the medical staff's work.

[0003] During the application of the existing arm auxiliary bracket for ultrasonic interventional treatment, the bracket itself has a single structure and function, and can only achieve the adjustment of the arm support angle, and mostly adopts a threaded method for angle control. It needs to be rotated multiple times to adjust to the appropriate angle. The operation is cumbersome, and the support height adjustment cannot be combined with the support angle adjustment. The arm support height is fixed, and the operation and use are limited. Summary of the invention

The two manual nuts are tightened and contacted with the assembly base to fix the support vertical rod, thereby ensuring the stability of the support vertical rod and allowing the medical staff's arms to work at a comfortable height.

[0015] In addition, the positioning plane and the limiting plane slide in cooperation to prevent the lifting sleeve from twisting. The lifting sleeve can be adjusted up and down according to the different support angles required for the arm. The lifting sleeve drives the arm support arc plate to rotate through the transmission support rod, thereby changing the angle of the arm support arc plate, which is better suitable for arm support needs at different angles. During ultrasonic interventional treatment, the medical staff's arms can work at a comfortable angle, reducing the difficulty of the medical staff's work. After the lifting sleeve is moved and adjusted, the locking outer hole and the through hole are in a connected state, and the locking pin located inside the locking outer hole moves inward, so that the inner end of the locking pin is inserted into the locking inner hole, and the lifting sleeve is fixed by the locking pin to ensure the stability of the arm support arc plate.

[0016] In addition, the spring plays an elastic reset effect on the unlocking active ring.

The unlocking active ring drives the locking pin to move inward, so that the inner end of the locking pin is inserted into the locking inner hole, ensuring the stability of the locking pin state. When the angle of the arc plate of the support arm needs to be adjusted, the unlocking movable circle is moved downward, the spring is compressed and force is accumulated, the linkage block gradually moves from the bottom end to the top end of the inclined sliding hole, and the unlocking movable circle drives the locking pin to move outward, so that the inner end of the locking pin is separated from the locking inner hole, and the movement of the lifting sleeve is unrestricted, the lifting sleeve can be moved up and down for adjustment, and the angle of the arc plate of the support arm can be adjusted.
