Abstract
The utility model relates to an elastic inside fixation steel plate which comprises an inserting plate with a T-shaped head and two base plates which are identical in shape and are provided with T-shaped grooves; the two base plates are mutually locked and welded to be fixed, the T-shaped head of the inserting plate is movably wrapped in the T-shaped grooves, intervals exist between the terminals of the T-shaped head of the inserting plate and the terminals of the T-shaped grooves of the two base plates, spring grooves are arranged at the terminal of the T-shaped grooves of the two base plates, a spring is arranged in each spring groove, and the T-shaped head of the inserting plate is elastically lapped with the spring; and the inserting plate and the two base plates are provided with bone nail threaded holes. The utility model can movably expand and contract in a certain limitation, can realize inching control on a fracture part, and can stimulate tissue metabolism of a fracture face to accelerate fracture healing.
Description
Technical field
This utility model relates to orthopedic medical device, particularly a kind of elasticity internal fixation steel plate.
Background technology
Fracture is people's normal diseases that take place in daily routines; its Therapeutic Method is various; wherein, the operation of internal fixation treatment closed fracture is extensively adopted, but in clinical practice; owing to use traditional internal fixation steel plate that the mutual alignment between two sections knochenbruch of postoperative is immobilized; in the process of union of fracture, the osteonecrosis that the broken ends of fractured bone has 1～2mm absorbs, and causes fracture end not connect; fracture face can not get stress stimulation, influences union of fracture.On the other hand, steel plate is fixing in the past needs big otch, cause the damage of fracture site muscle fiber, and the periosteum stripping marrow enlarges, destruction that can be in various degree the blood fortune of bone itself, also influenced the healing of fracturing.
Summary of the invention
For overcoming the shortcoming of prior art, goal of the invention of the present utility model provides a kind of elasticity internal fixation steel plate, this elasticity internal fixation steel plate has the plate of T shape head by a slice and seat board elasticity that a slice has T-slot connects and composes, this elasticity internal fixation steel plate can be in certain limit movable telescopic, can realize fracture site fine motion control, can stimulate fracture face tissue metabolism, accelerating union of bone fracture.
The purpose of this utility model is achieved in that a kind of elasticity internal fixation steel plate, and described elasticity internal fixation steel plate comprises that a slice has the seat board of the identical T of the having connected in star with 2 plate shapes of plate of T shape head; It is fixing that described 2 seat boards fasten welding mutually, a T shape active packet of described plate is overlayed in the described T connected in star, gapped between the T connected in star end of the T shape cephalic par of described plate and described 2 seat boards, the T connected in star end of described 2 seat boards is provided with spring groove, spring is housed, the T shape cephalic par of described plate and described spring overlap joint in the spring groove; Described plate and described 2 seat boards are provided with the nail screwed hole.
The T connected in star place of described 2 seat boards is provided with the nail screwed hole, and the T shape head of described plate is provided with the nail perforation, and described nail perforation is corresponding with the nail screwed hole that described T connected in star place is provided with, and described nail perforation is greater than the nail screwed hole.
The beneficial effect that this utility model produces is:
1, connects and composes by plate and 2 seat board elasticity that have the T connected in star that a slice has T shape head owing to this utility model, plate and seat board can be in certain limit movable telescopic, fracture site fine motion control can be realized, fracture face tissue metabolism can be stimulated, accelerating union of bone fracture.
2, because clinically when using this utility model, the big otch that does not need depth, need not carry out periosteum stripping, only need the percutaneous incision skin tissue that this utility model is fixed knochenbruch with the full thread nail, again skin histology is sewed up, can not cause damage of fracture site muscle fiber and periosteum stripping marrow to enlarge, can not destroy the blood fortune of bone itself, the healing that helps fracturing.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is this utility model front view;
Fig. 2 is that the C of Fig. 1 is to view;
Fig. 3 is the A-A cutaway view of Fig. 1;
Fig. 4 is the B-B cutaway view of Fig. 2.
The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, present embodiment has provided preferred forms of the present utility model.Elasticity internal fixation steel plate in the present embodiment comprises that a slice has the seat board 1,4 of the identical T of the having connected in star 5 with 2 plate shapes of plate 2 of T shape 9; The T shape active packet that 2 seat boards fasten mutually with plate overlays in the T connected in star, and 2 seat board binding faces welding interfix 2 seat boards.The T connected in star end of gapped 8,2 seat boards is provided with spring groove 6 between the T connected in star end of the T shape cephalic par of plate and 2 seat boards, and spring 7 is housed in the spring groove, the T shape cephalic par of plate and spring overlap joint; Plate and 2 seat boards are provided with nail screwed hole 3.
When using this utility model clinically, do not need the big otch of depth, need not carry out periosteum stripping, only need the percutaneous incision skin tissue this utility model and knochenbruch to be fixed together, again the skin histology stitching is got final product with the full thread nail.Because this utility model is connected and composed by plate and 2 seat board elasticity that have the T connected in star that a slice has T shape head, plate and seat board can be in certain limit movable telescopic, can realize fracture site fine motion control, can stimulate fracture face tissue metabolism, accelerating union of bone fracture, and can not cause damage of fracture site muscle fiber and periosteum stripping marrow to enlarge, can not destroy the blood fortune of bone itself, the healing that helps fracturing.
In the present embodiment, the T connected in star place of described 2 seat boards is provided with nail screwed hole 10, the T shape head of described plate is provided with nail perforation 11, and described nail perforation is corresponding with the nail screwed hole that described T connected in star place is provided with, and described nail perforation is greater than the nail screwed hole.Promptly 2 nail fixed bits are set again, can improve the stability of this utility model fixation of bone fragments in the junction of plate and 2 seat boards.
