[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This muscle and soft tissue dissection needle, through the setting of a fixed rod, needle bar, limiting slider, and limiting block, allows for the following operation: when the needle bar is pulled, the fixed rod limits its movement, while the limiting slider slides on the inner wall of the fixed rod, thus limiting the needle bar. When the needle bar is pulled to a certain length, the limiting block engages with the groove on the inner wall of the fixed rod, thereby fixing the position of the needle bar. This allows for adjustment of the overall length of the needle to adapt to different surgical sites, improving the adaptability of the device and avoiding the limitations of traditional dissection needles where the length is fixed and difficult to adjust, and the need for dissection varies depending on the location of the tissue to be dissected.

[0014] 2. This muscle and soft tissue dissection needle, through the design of the needle, protective sleeve, connecting rope, connecting ring, connecting plate, and locking block, is used by placing the connecting ring on the surface of the device, then fitting the two connecting plates together, so that the locking block is engaged in the groove on the surface of the other connecting plate, thereby fixing the position of the connecting ring. Then, the protective sleeve is placed on the surface of the needle to protect the needle, thereby enhancing safety and avoiding the situation where the needle surface is not protected during transportation or storage, which could easily lead to accidental needle punctures on medical personnel.
