Abstract
The utility model discloses a novel bone fracture plate, which belongs to medical equipment. A through hole of a bone fracture plate body goes through the bone fracture plate body from the top side surface to the bottom side surface and is formed by connecting a spherical hoe or a screwed hole and a bolt displacement hole; the bottom side surface is arc-shaped; side arc bosses are formed on two sides of the bone fracture plate body; and two bone fracture plate bodies are mutually connected into a whole body through an arc notch board. The spherical hoe is convenient for the novel bone fracture plate to be connected and fixed to a spherical cap screw; the novel bone fracture plate ensures that bone screws are fixed at different angles along the axis of the bone fracture plate; the screwed hole ensures that a gap is formed between the bone fracture plate and the surface of a bone, no pressure exists between the bone fracture plate and cortex of bone, and normal blood supply is guaranteed; the side arc bosses prevent periost from being destroyed, and reduce the fracture healing period; and arc groove performs molding on the bone fracture plate, and effectively connects and fixes bone stumps.
Description
Affiliated technical field:
This utility model belongs to a kind of medical apparatus and instruments, and the internal fixation apparatus that particularly a kind of bone surgery is used has the novel blade plate in limit arc boss, arc groove and screw displacement hole.
Background technology:
Blade plate is the equipment commonly used that connects the skeleton broken ends of fractured bone in the bone surgery, and the blade plate of selecting for use according to different parts does not possess the project organization of this utility model.So skeleton produced blocks stress, periosteum is produced certain pressure, very easily cause the local osteoporosis of skeleton and fracture again.The screw of blade plate and outfit also becomes flexible owing to the skeleton delayed union or ruptures.
The utility model content:
The technical problem that this utility model solved is to overcome above-mentioned technical deficiency, be designed to rational in infrastructure, easy to use, stressed evenly, shorten the novel blade plate of clinical healing phase.
The technical scheme of the problems referred to above that this utility model solved is: a kind of novel blade plate; It is characterized in that: it comprises the blade plate body; The blade plate body comprises the bottom side and the through hole of top side face, contact bone; Through hole passes the blade plate body from top side face to bottom side and is communicated with, through hole be by from top side face spherical pore along blade plate thickness or screwed hole and from bottom side the screw displacement hole along the blade plate thickness direction is connected and forms, screw displacement hole has female thread; The bottom side of blade plate body is a circular shape; The dual-side of bottom side is provided with limit arc boss, connects as one with the arc notch board between two blade plate bodies, and the blade plate body connects into straight type one blade plate.
Said screw displacement hole be go up short long down, be trumpet-shaped screw hole.
Said blade plate body is connected to the special-shaped blade plate of edge bifurcated.
The advantage and the beneficial effect of this utility model are:
1, in the blade plate body of this utility model, the design of spherical pore is convenient to various bone screws and is connected according to the fracture site wound degree and fix;
2, the design in screw displacement hole can guarantee that bone screw carries out the fixing of multi-angle along the blade plate axis, particularly to pulverizing the fixing of bone piece;
3, the design of screwed hole can make blade plate and bone surface keep certain interval, and making between blade plate and cortical bone does not have plus-pressure, guarantees that blood fortune is normal, alleviates the influence to the fracture peripheral soft tissues;
4, limit spaced apart, the both sides of blade plate arc boss, to reduce the stress shielding to skeleton, so periosteum is not produced pressure, the protection periosteum is not destroyed, thereby shortens the union of fracture phase;
5, the design of arc groove can be carried out plastotype to blade plate, the more effective connection of carrying out bone stump and fixing;
6, the internal fixation principle of following in neurosurgery, the bone surgery designs, and anti-fatigue performance is high, and moulding excellent performance is suitable for the fracture fixation at cranium jaw face, brothers and extremity position, is applicable to clinical demand more.

The specific embodiment:
Embodiment: shown in Fig. 1-3; This utility model is further specified: a kind of novel blade plate that has limit arc boss, arc groove and screw displacement hole; It comprises blade plate body 1; Blade plate body 1 comprises the bottom side 3 and the through hole 4 of top side face 2, contact bone, and through hole 4 passes blade plate body 1 from top side face 2 to bottom side 3 and is communicated with, and through hole 4 is that 6 linkings of the screw displacement hole along thickness direction form along the spherical pore 5 of blade plate thickness with from bottom side 3 by top side face 2; Screw displacement hole 6 be go up short long down, be trumpet-shaped screw hole; Be provided with female thread, the design of spherical pore is convenient to various bone screws and is connected according to the fracture site wound degree and fix, and is convenient to fix with being connected of spherical cap screw; The design in screw displacement hole can make bone screw carry out the fixing of multi-angle along the blade plate axis, is specially adapted to the fixing of syntripsis; The bottom side 3 of blade plate body 1 is an arc structure 9, matches with the skeleton surface, can guarantee firm fixing; Bottom side 3 dual-sides of blade plate body 1 are provided with limit arc boss 7, are connected to the integrative-structure of straight type between a plurality of blade plate bodies 1 with arc notch board 8; The effect of limit arc boss can reduce the stress shielding to bone surface, and periosteum is not produced pressure, and the protection periosteum is not destroyed, and prevents that skeleton from fractureing again, thereby shortens the union of fracture phase; The design of arc groove can be convenient to blade plate is carried out plastotype, the more effective connection of carrying out bone stump and fixing;
The blade plate body is connected to the abnormally-structured design of edge bifurcated among Fig. 4-5, is convenient to clinical mouldingly, guarantees blade plate and skeleton kissing merging firm fixation.
The blade plate that above structure is formed can adapt to the bone surgery various disease conditions, and postoperative does not influence the growth of periosteum, and the bone stump growth is fast, and makes patient's early recovery.
