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

The invention provides a minimally invasive intramedullary fixing device for clavicle fracture, belongs to the technical field of medical instruments of orthopedics and is used for minimally invasively fixing clavicle fracture at the intermediate piece. The technical scheme is as follows: a proximal intramedullary nail and a distal intramedullary nail are respectively inserted into fractured marrow cavities at the proximal end and the distal end of the clavicle fracture, the proximal intramedullary nail and the distal intramedullary nail are fixedly connected through a fixing screw, a proximal end reset nail, a distal end reset nail and a pull rod are used for tensioning and resetting the two parts of the clavicle fracture towards the middle, after the fracture is healed, the distal end of the clavicle is opened to take out the proximal intramedullary nail and the distal intramedullary nail from the clavicle through a taking out rod, and the operation is carried out under a minimally invasive condition. The minimally invasive intramedullary fixing device provided by the invention is reasonable in structure, simple in operation and firm to fix, achieves minimal invasiveness and minimal X ray exposure and effectively fix the fracture. The minimally invasive intramedullary fixing device provided by the invention is an innovation in minimally invasive fracture operation, effectively avoids the defects of traditional clavicle fracture fixation incision operation, greatly shortens the operation time and recovery time and effectively relieves the pain 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 ...
