Lower limb resetting device for intramedullary nail surgeries

Abstract

The invention discloses a lower limb resetting device for intramedullary nail surgeries. The lower limb resetting device for intramedullary nail surgeries comprises a rectangular bottom plate, a telescopic shank supporting plate, a thigh backup plate, a kirschner wire and a tensioning bow, wherein the rectangular bottom plate is horizontally placed on an operating bed; the telescopic shank supporting plate is hinged with the upper end of the thigh backup plate; the lower end of the telescopic shank supporting plate and the lower end of the thigh backup plate are respectively hinged with the two ends of the rectangular bottom plate; in surgery, the thigh and the shank of a patient lean against the upper portion of the thigh backup plate and the upper portion of the telescopic shank supporting plate respectively, the kirschner wire penetrates through the far end of the ankle bone or the tibia of the patient, the two ends of the kirschner wire are connected to the two ends of the tensioning bow respectively, and each end of the tensioning bow is connected with the telescopic shank supporting plate through an adjustable support. The patient can be kept in a leg bending state, the tibiaor thighbone of the patient can be reliably pulled, all parts are not higher than the lower limb of the patient, and surgical operation is not affected. The lower limb resetting device can ensure that a tibia or femoral intramedullary nail implantation operation is smoothly carried out, and the operation quality and efficiency are improved.

Description

technical field [0001] The invention relates to a lower limb reset device suitable for femoral and tibial intramedullary nail implantation operations, and belongs to the technical field of orthopedic medical devices. Background technique [0002] Tibial fractures are common clinical fractures. Due to the strong muscle strength of the legs, patients with tibial fractures often experience shortening deformities under the pull of the muscles. 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 is a common treatment method for tibial or femoral fractures, and intraoperative traction is an important means to re...

AI Technical Summary

Problems solved by technology

At present, during intramedullary nail implantation, two assistants are generally required to help traction the patient. The two assistants respectively hold the proximal end and the distal end of the tibia or femur to reduce the tibia or femur. However, this method often cannot stably maintain 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

[0004] Using a traction device to reset the fractured tibia or femur can overcome the above-mentioned shortcomings, but the existing traction devices generally need to occupy the upper part of the patient's lower limb space, which affects the operation, and the existing traction devices all make the lower limbs straight, and the marrow The inner nail is implanted from the end of the tibia or femur, and the patient must maintain a bent-leg posture for surgery
