[0002] A fracture is a disruption to the integrity or continuity of a bone. In most cases, fractures can be treated through non-surgical methods such as rest, immobilization, and rehabilitation. However, in some cases, fractures may require surgery to repair and fix them. During fracture surgery, the doctor will use a fracture positioning jig to assist the operation in aligning the fracture ends and keeping them in the correct position.

[0003] However, in the prior art, although the existing fracture positioning clamp can align the two ends of the fractured bone and keep them in the correct position during actual use to facilitate the operation, it does not have the function of providing positioning and punching for fixing the steel plate, which means that the doctor has to use other positioning devices to perform positioning and punching operations on the bone later, which increases the complexity of the operation and increases the operation time, which not only reduces the scope of use of the fracture positioning clamp, but also reduces the efficiency of the use of the fracture positioning clamp.

[0004] Therefore, we propose a fracture positioning fixture to solve the technical problems raised in the background technology. Utility Model Content

[0027] The effect achieved is that when the doctor needs to use the fracture positioning fixture to provide positioning and punching operations for the fixed steel plate during the fracture surgery, the two ends of the fractured bone are first aligned and kept in the correct position, and then the shell 1 is moved to the fracture position so that the fracture position is inside the shell 1, and then the position of the shell 1 is adjusted so that the first rectangular hole 201 is directly above the hole where the fixed steel plate needs to be punched. When the position of the shell 1 is adjusted, the four second hand-tightening bolts 4 are rotated in turn. At this time, each of the rotated second hand-tightening bolts 4 will drive the corresponding soft pad 6 to move with the cooperation of the bolt hole 3 and the cylindrical plate 5 until each soft pad 6 is in contact with the bone.
