However, percutaneous reduction and internal fixation for extremity fractures cannot be applied and no one has applied them.
[0003] In the existing external fixation brackets for fractures, some brackets cannot be adjusted, which leads to extreme inconvenience in use, but the adjustable brackets are often easy to twist because of the unstable structure, which will cause secondary damage to the affected part of the patient and aggravate the pain. patient suffering

Embodiment approach
[0040] The specific implementation method is as follows: the first limiting sleeve 10 is threadedly connected to the top of the nail bone pin 6, and the first limiting sleeve 10 meets the needle sleeve 5 to stop falling during the downward process of the nail bone pin 6, which is convenient for controlling the nailing depth and preventing insertion. Too deep will cause harm to the patient. Both the bracket base plate 1 and the extension frame 2 are made of high-strength engineering plastics to achieve high strength while ensuring lightness. The binding bandage 13 fixes the affected part of the human body, avoiding secondary damage to the human body caused by the shaking of the nail bone needle 6. In addition, the protruding slider 18 cooperates with the stopper 19 to prevent the extension frame 2 from slipping out, and the buffer spring 16 improves the movement of the extension frame 2. stability, the first scale bar 14 is convenient for controlling the pull-out length of the e...

The invention discloses an external fixing bracket for fracture, and particularly relates to the technical field of medical instruments. The bracket comprises a bracket substrate. Two ends of the bracket substrate are respectively provided with an extension frame. One end of each extension frame away from the bracket substrate is fixedly connected with a connecting rod, a fixed ferrule is fixedlyconnected to the outer side of each connecting rod, a needle guard is in rotating connection in the fixed ferrule, and a bone nail is arranged in each needle guard. A clamping groove, a first limitingsliding rod and a second limiting sliding rod are respectively matched with a rack plate, a first limiting sliding groove and a second limiting sliding groove, so that the extension frames and the bracket substrate slide. The movement track of the two extension frames is limited, a twisting handle is twisted to make a gear rotate to be meshed with a rack plate to adjust the extension length of the bracket substrate and the angle between the needle guards and the fixed ferrules is adjusted, so that the angle of the bone nails can be adjusted. The length and the angle can be flexibly adjusted to facilitate bone fixing, the stability of the bracket is improved, and the pain of a patient can be reduced.
Description
technical field [0001] The invention relates to the technical field of medical instruments, and more specifically, the invention relates to a fracture lateral fixation bracket. Background technique [0002] At present, fracture fixation includes internal fixation and external fixation techniques. Internal fixation is currently mainly internal fixation with steel plates and screws. The periosteum is often stripped and the reset process is complicated. The main problem is that if the fracture is not tightly aligned after the screw is driven in, it will not be able to adjust. Moreover, the blood supply of the fracture end is greatly damaged. In Weigao orthopedics and spine surgery, there are widely used screw-rod fixation systems for the spine. The structures of various screw-rod fixation systems are similar, and the fixation strength is high. They are mainly used for internal fixation of the thoracolumbar spine. And can't apply also nobody is applied to the percutaneous reduc...
