First-aid reduction device for open tibia fracture

Abstract

The invention discloses a first-aid reduction device for open tibia fracture. The first-aid reduction device comprises a supporting body and a traction reduction mechanism detachably fixed to the supporting body. A patient lies flat, the feet of the patient are fixed on the lower supporting section, and the fracture can be reduced and the length of the lower limbs can be recovered by controlling the lower supporting section to move away from or close to the middle supporting section. The lower supporting section can rotate leftwards and rightwards relative to the main body, and the tiptoe of a patient faces upwards through rotation adjustment, so that inward rotation or outward turning of broken bones at the far end of a fracture line is corrected; then the near end of the lower supporting section is driven to rise, so that the patient is in a knee bending state, the patella of the patient faces upwards, and inward rotation or outward turning of broken bones at the near end of the fracture line can be corrected in the knee bending process. A three-dimensional traction frame acts on the traction nail, and by pulling the traction nail to move up and down and left and right, traction reduction of lateral angulation deformity and front and back angulation deformity at the near end and the far end of a fracture line can be carried out.

Description

technical field [0001] The invention relates to the technical field of orthopedic medical devices, in particular to an emergency reduction device for tibial open fractures. Background technique [0002] Femoral fracture is a common clinical fracture. Due to the strong muscle strength of the leg, patients with tibial fractures often experience shortening deformity under the pull of the muscle. It is difficult to reset, restore its length and maintain it effectively during the operation. If the anatomical reduction cannot be performed during the operation, complications such as malunion and poor alignment of the lower limbs may occur after the operation, which may lead to traumatic arthritis or osteoarthritis, seriously affecting the limb function and quality of life of the patient. [0003] Intramedullary nailing or percutaneous minimally invasive bone plate implantation are commonly used treatment methods for tibial fractures, and intraoperative traction is an important mean...

AI Technical Summary

Problems solved by technology

At present, when implanting intramedullary nails or percutaneous minimally invasive implantation of bone plates, two assistants are generally required to help traction the patient. The two assistants hold the proximal end and the distal end of the broken bone respectively to reset the tibia. However, this method often cannot Stable maintenance of fracture reduction and lower limb length, the reduction effect is not ideal, which affects the treatment effect; and the two assistants will occupy the space of the surgeon, affecting the operation of the surgeon
