Assembled and adjustable clavicle fixing device with reduction function and use method of assembled and adjustable clavicle fixing device

Abstract

The invention discloses an assembled and adjustable clavicle fixing device with a reduction function and a use method of the assembled and adjustable clavicle fixing device. The device comprises fixing blocks which are respectively arranged on a clavicle, an adjusting block and two connecting cables, wherein each fixing block comprises a base plate I, channels I formed in the left side and the right side of the base plate I in the axis direction and a screw hole formed in the top end of the corresponding first base plate; the adjusting block is arranged on the clavicle; the adjusting block comprises a base plate II, and second channels which are close to the side walls of the two ends of the base plate II and are symmetrical about the center line; the connecting cables sequentially penetrate through the channels I and the channels II in the two sides of the fixing blocks and the adjusting block respectively and then are fixed through lock catches, and according to the assembled and adjustable clavicle fixing device with the reduction function and the use method of the assembled and adjustable clavicle fixing device with the reduction function, the fixing blocks and the adjusting block are used in an assembled mode; and the device has the characteristics of synchronous fixation and reduction, adjustability, universality, simplicity in operation and the like, can be used for various clavicle fractures, and has a better effect.

Description

technical field [0001] The invention relates to the technical field of orthopedics clinical application, in particular to a modular adjustable clavicular fixation device with a reset function and a method for using the same. Background technique [0002] Clavicle fractures are common clinically and require surgical treatment in severe cases. Most fractures are fixed with bone plates after reduction. Shape design and production of anatomical bone plates, plate screws can be locked or even customized, etc., but there are still some problems that need to be effectively resolved, such as: [0003] 1. At present, bone plates are mainly used to maintain reduction and fixation, and do not have the function of fracture reduction; [0004] 2. The bone plate cannot be extended or shortened, and the distance of the fixation hole cannot be adjusted individually. Therefore, a large number of different types of bone plates are required for surgery, and they may not be suitable; [0005]...

AI Technical Summary

Problems solved by technology

[0003] 1. At present, bone plates are mainly used to maintain reduction and fixation, and do not have the function of fracture reduction;

[0004] 2. The bone plate cannot be extended or shortened, and the distance of the fixation hole cannot be adjusted individually. Therefore, a large number of different types of bone plates are required for surgery, and they may not be suitable;

[0005] 3. Fractures around the joint sometimes need to be fixed across the joint, resulting in loss of joint function;

[0006] 4. The shape of the clavicle is irregular, and the adjustment method and degree of the existing bone plate are limited, and the operation process is complicated;

[0007] 5. The traditional clavicular bone plate is rigidly fixed, which is prone to stress concentration at the fracture site, and complications such as plate loosening, fracture, and fracture nonunion after surgery
