Problems solved by technology

With the development of minimally invasive surgery, the use of minimally invasive surgery in orthopedic surgery is becoming more and more common, but there is no precedent for the use of minimally invasive surgery in the surgical treatment of clavicle fractures, especially the use of reduction plates for reduction and fixation is difficult to compare with minimally invasive surgery Combined, so minimally invasive surgery in clavicle fracture surgery has become an intractable problem

Embodiment Construction

[0021] The present invention consists of a proximal intramedullary nail 1, a distal intramedullary nail 2, a fixing screw 7, a proximal reset nail 8, a distal reset nail 9, a pull rod 10, a top wire 12, a front and back lock nut 13, and a positioning pin 15. , Take out rod 16 and form. When in use, the proximal intramedullary nail 1 and the distal intramedullary nail 2 are respectively inserted into the medullary cavity of the clavicular fracture on both sides, and the fixing screw 7 connects the proximal intramedullary nail 1 and the distal intramedullary nail 2 firmly. The proximal intramedullary nail 1 and the distal intramedullary nail 2 can be connected in two forms. The first type is in the shape of an "S" and matches the shape of the clavicle; the second type is in the shape of a straight nail. The corresponding pull rod 10 also has two shapes, which are compatible with the intramedullary nail. After the first connection, the overall shape is "S", which matches the shap...

Abstract

A minimally invasive intramedullary fixation device for clavicle fractures belongs to the technical field of orthopedic medical devices and is used for minimally invasive fixation of clavicle fractures. The technical scheme is: insert the proximal intramedullary nail and the distal intramedullary nail into the fractured bone medullary cavity of the clavicle fracture respectively, and fix the proximal intramedullary nail and the distal intramedullary nail with the fixing screws , the proximal reduction nail, the distal reduction nail and the pull rod tighten the two parts of the clavicle fracture toward the middle and reset them. After the fracture heals, an opening is opened at the distal end of the clavicle. The surgical procedure is carried out under minimally invasive conditions. The invention has the advantages of reasonable structure, simple operation and firm fixation, realizes minimum trauma and minimum X-ray exposure, and achieves the purpose of effectively fixing fractures. The invention is an innovation of minimally invasive surgery for fracture fixation, effectively avoids the disadvantages of traditional clavicle fracture fixation and incision, greatly shortens the operation time and recovery time, and effectively reduces the suffering of patients.

Description

technical field [0001] The invention relates to an intramedullary fixation device for minimally invasive fixation of middle clavicle fractures, and belongs to the technical field of orthopedic medical devices. Background technique [0002] Minimally invasive treatment is a new treatment method developed in the medical field in recent years, which represents a new direction for the development of surgical medical technology. Compared with traditional surgery, minimally invasive treatment has the advantages of small wounds, thin scars, less blood loss during surgery, less pain for patients after surgery, and faster recovery, and is more and more popular among doctors and patients. The development of contemporary science and technology provides a strong guarantee for minimally invasive treatment. Under the guidance of X-ray machines, CT and advanced electronic and optical equipment, doctors can use special instruments and various instruments to perform operations. With the dev...
