Detailed Description
The first embodiment is a tibia proximal end positioning module for a tibia high-level osteotomy guide plate, which comprises a tibia proximal end fixing plate 01 formed by 3D printing and a Kirschner wire guide column 02 fixed on the tibia proximal end fixing plate, wherein Kirschner wire guide holes are formed in the corresponding positions of the tibia proximal end fixing plate and the Kirschner wire guide column. During operation, the inner surface of the proximal tibia fixing block is attached to the bone surface, the proximal tibia fixing block is fixed by hands, the Kirschner wire is drilled into the bone along the guide hole, then the proximal tibia positioning module is detached, and then the bone is cut along the Kirschner wire by the swing saw, so that the operation time is shorter, the position of the bone is positioned accurately, the X-ray exposure times in the operation are less, the operation incision is short, and the soft tissue trauma is small.
In the second embodiment, a k-wire fixing column 03 is fixedly arranged on the proximal tibia fixing plate, and k-wire fixing holes are formed in the corresponding positions of the proximal tibia fixing plate and the k-wire fixing column. The purpose of design is earlier with the kirschner wire along the fixed hole drilling bone in, fixes to tibia near-end positioning module through the kirschner wire, avoids the condition that tibia near-end positioning module and bone face are inaccurate when the kirschner wire is bored along the guiding hole drilling bone in to appear.
In a third embodiment, the kirschner wire guide column and the kirschner wire fixing column are both provided with a metal insert 04, and the metal insert is provided with a kirschner wire hole corresponding to the kirschner wire guide Kong Jike kirschner wire fixing hole. The purpose of design is that the kirschner wire can not touch fixed orifices or guiding holes in the drilling process, because the material of the proximal tibia positioning module is a nonmetallic material, powder can be produced in the drilling process, the curative effect of surgery can be influenced, or the physical health of a patient can be harmed, and metal inserts are arranged on the kirschner wire guiding column and the kirschner wire fixing column, so that the kirschner wire is not in direct contact with the guiding holes and the fixing holes, and the powder is prevented from being produced in the drilling process.
Further, a connecting rod 05 is fixedly arranged on the tibia proximal end fixing plate, and during operation, the inner ankle and outer ankle positioning module is fixed with the inner ankle and outer ankle of a human body, and then the tibia proximal end positioning module is connected with the inner ankle and outer ankle positioning module through the connecting rod. The aim of the design is to prevent the dislocation movement of the proximal tibia positioning module in the process of drilling the kirschner wire, thereby affecting the curative effect of the operation or endangering the physical health of patients.
Further, the proximal tibia fixing plate is of a split structure and comprises a first fixing plate, a second fixing plate and a connecting piece 06 fixedly connected between the first fixing plate and the second fixing plate, and the Kirschner wire guide post is fixedly arranged on the first fixing plate.
