The clavicle is S-shaped and arranged between the sternum handle and the acromion, and is the only bone bracket for connecting the upper limb and the trunk. The clavicle is positioned under the skin and superficial, and is easy to fracture under the action of external force, and the incidence rate of the clavicle accounts for 5% -10% of that of the fracture of the whole body.
The traditional clavicle fracture operation needs to cut a large incision for operation, long scars can be left after the incision reduction and internal fixation, and skin nerves are easily damaged to cause local skin numbness, and the appearance is influenced especially for women. The minimally invasive clavicle fracture internal fixation operation is carried out as soon as possible. In minimally invasive internal fixation, tissue forceps, pointed bone holding forceps, reduction forceps and the like are generally used for reduction and fixation of clavicle fracture. Due to the complex shape of the clavicle (S-shaped, with the outer side 1/3 of the clavicle protruding flat up and down and rearward and the inner side 2/3 protruding forward in a triangular prism), these devices are difficult to fix relatively complex fracture sites and unstable fixation occurs. Therefore, the minimally invasive clavicle fracture reduction fixing device is invented to solve the existing problems. Application number is 200910014383.7 a clavicle fracture resetting means, characterized by that two nippers of the left and right sides are constituteed, every nipper comprises handle, pincers handle and tong arm, the hinge portion of two nippers of the left and right sides passes through ball head adjusting bolt and links as an organic whole, the ball head at ball head adjusting bolt both ends with set up the ball socket hinged joint of controlling the upper end of nipper tong arm, link together through the nut of taking forward and reverse screw thread in the middle of the ball head adjusting bolt. There are the following disadvantages: (1) the relative positions of the two grasping forceps are adjusted only by the ball head, the moving range of the grasping forceps is not large enough, and the grasping forceps are difficult to fix when meeting fracture parts with complex shapes; (2) the adjustable locking bolt and the adjustable locking nut at the lower end of the nipper arm have small operable space and are inconvenient to operate; (3) when the medical treatment device is fixed, the number of the positions needing to be adjusted reaches 8, so that the treatment time is delayed, the workload of medical staff is increased, and the pain of a patient is increased.
