fig. 2 is a schematic view of a partial section structure of a steel plate in the orthopedic internal fixation device of the present invention.
In the figure: the steel plate is 1, the fixing holes are 2, the locking holes are 3, the pressurizing holes are 4, the moving holes are 5, the first placing grooves are 6, and the second placing grooves are 7.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, an internal fixation device for orthopedics comprises a steel plate 1.
The 1 corner of steel sheet is the fillet setting, and then can reduce steel sheet 1 and to the stimulation of human body, reduce the painful sense of postoperative, and the cross section of steel sheet 1 is ARC structure, and then makes steel sheet 1 and skeleton laminate more, further reduces the stimulation of steel sheet 1 to the human body, and steel sheet 1 all realizes the fixed to the skeleton through low grub screw, and then reduces the thickness of screw tip, and then reduces the stimulation of screw tip to the human body.
The steel plate 1 is provided with a plurality of 8-shaped fixing holes 2 symmetrically arranged about a fixing center, the fixing center of the steel plate 1 is a fracture part, the fixing holes 2 are composed of locking holes 3 and pressurizing holes 4, the locking holes 3 are communicated with the side walls of the pressurizing holes 4, and the diameter of each pressurizing hole 4 is larger than that of each locking hole 3.
The pressurizing hole 4 can pressurize the bone, and after pressurization is finished, the steel plate 1 and the bone are locked through the locking hole 3.
As shown in fig. 2, the top end of the sidewall on one side of the pressurizing hole 4 is an inclined arc structure, and the pressurizing holes 4 in the fixing holes 2 which are arranged oppositely are all provided with inclined arc structures on the sidewall on one side which is far away from each other.
When the screw is pressed down in the pressurizing hole 4, the screw can generate certain offset under the action of the inclined cambered surface part of the pressurizing hole 4, so that the two sections of fractured bones are driven by the screw to be close to each other, the bone is pressurized by the screw, the screw is automatically pressurized when being fixed, and the screw is not required to be fixed by an additional pressurizer.
