Problems solved by technology

[0003] The above-mentioned existing rib spreader has the following disadvantages: 1. Since the fixed spread arm and the movable spread arm are always parallel in the process of stretching the ribs, but the ribs are not parallel to each other when stretching, This can easily cause uneven stress on the ribs, resulting in damage or even fracture of the ribs, which increases the pain of the patient.

2. The shape of the existing fixed spreader arm and movable spreader arm is fixed (straight or with a fixed curved radian), and cannot be adjusted according to the rib shape of different patients. There are cases of incompatibility, which will also cause ribs Uneven force, leading to rib damage or even fracture
