Description

Technical Field

[0001] The utility model relates to the technical field of anatomical auxiliary equipment, in particular to an arm fixing device for anatomical use. Background Art

[0002] Currently, when dissecting human specimens, they are usually placed on a dissecting table for support and fixation. However, after being perfused with formalin, the human specimens gain weight and their limbs become stiff, so that local fixation is unstable and flipping is inconvenient during field operations.

[0003] Patent No. 202320497886.X discloses an anatomical support adapter. When dissecting a human arm, the first servo motor is started to drive the rotating block to rotate as needed, thereby driving the second support seat to rotate, thereby driving the forearm and the upper arm to rotate, and the second servo motor is started to drive the connecting block to rotate, thereby driving the first support seat to rotate, and then lifting and lowering the root of the upper arm. During the installation process, the arm of the human specimen needs to pass through the first positioning frame and the second positioning frame, and then the first inflatable bag and the second inflatable bag are used to clamp and restrict. The arm is placed on the first support seat, the second support seat and the third support seat, and the arm can be rotated and swung through the rotating block, the rotating shaft and the connecting block. There are the following problems during use:

[0004] 1. Due to the stiffness of the limbs of the human specimen, it is cumbersome to insert the arm into the first positioning frame and the second positioning frame each time the arm is fixed. When the arm needs to be turned over, the first and second air bags need to be reduced first, so that the first support seat and the second support seat are in a straight line before turning over, and then inflate and press tightly, which makes it impossible to quickly and effectively fix the arm;

[0005] 2. When the arm is bent, the first servo motor and the second servo motor are required to control the swing, which is costly and requires waiting for the movement time of the motor, and lacks flexibility. Utility Model Content

[0011] As a preferred solution, the clamping claw is hinged on the telescopic sleeve via a hinge shaft, and an adjusting nut for pressing and fixing the clamping claw and the telescopic sleeve is also provided at the hinge shaft.

[0012] As a preferred solution, the accommodating slot is a U-shaped slot.

[0013] As a preferred solution, a rope threading hole is provided on the groove edge of the card receiving groove.
