Description
Technical field
The present invention relates to medical appliance fields, particularly relate to a kind of four side butterfly steel plates for the locking of children's epiphysis.
Background technique
Long bone both ends enlargement is known as epiphysis, and epiphysis and epiphyseal plate are all the growth districts of immature long bone of limbs,
It is the most important position of growth of children's bone.Epiphysis congenital dysplasia or epiphyseal injury can cause the growth of metaphysis to hinder
Hinder, leads to limb shortening or joint deformity.
Currently, cacomelia caused by epiphyseal dysplasia or epiphyseal injury mostly uses osteotomy to add the operation side of steel plate screw
Method, this method damages larger, the incidence height of postoperative complication to infant sclerotin result, including infects, deformity recurrence, straightens crooked
Cross just, Plate break, osteotomy surface delayed union and the problems such as disunion.
Summary of the invention
The purpose of the present invention is to provide a kind of four side butterfly steel plates for the locking of children's epiphysis, for solving existing skill
The problems such as sclerotin injury is greatly in art and the incidence of complication is high.
To achieve the above object, the present invention provides following technical scheme：
A kind of four side butterfly steel plates for the locking of children's epiphysis are in the steel plate ontology of four side butterflies including shape, described
There is angle between steel plate body upper part and the steel plate body lower part, 4-6 are laid on the steel plate ontology and is used to admittedly
Determine the threaded hole of attachment screw, and between the screw and the steel plate ontology have angle, the steel plate ontology it is symmetrical in
Location hole and groove are equipped at the heart.
Wherein, it is mounted on the screw of the steel plate body upper part and is mounted on the screw of the steel plate body lower part mutually not
In parallel.
Wherein, be mounted on angle between the screw of the steel plate body lower part and the steel plate body lower part in 105 °-
115°。
Wherein, the angle between the steel plate body upper part and the steel plate body lower part is in 155 ° -165 °.
Wherein, be mounted on angle between the screw of the steel plate body upper part and the steel plate body upper part in 105 °-
115°。
Above-mentioned technical proposal of the invention has the beneficial effect that：
In above scheme, after the screw is fixed on steel plate ontology, with the growth of children's epiphysis, by described
The angle between angle and steel plate ontology and screw between steel plate body upper part and the steel plate body lower part can elasticity
The epiphysis of children is locked, the growth of children's side seam epiphysis is temporarily blocked, correction has deformed limbs；It is mounted on the steel plate ontology
The screw on top is not parallel mutually with the screw for being mounted on the steel plate body lower part, increases the resisting pull out forces of the screw；This
The design of the steel plate and screw of invention reduces the vertical stress that epiphyseal growth generates screw, reduces the wind of screw breakage
Danger；Steel plate of the invention to children to because caused by epiphyseal dysplasia cacomelia orthopedic effect it is good, reduce it is postoperative simultaneously
Send out the incidence of disease.

Specific embodiment
To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool
Body embodiment is described in detail.
The present invention provides a kind of use for existing sclerotin injury in the prior art is big and the high problem of incidence of complication
In four side butterfly steel plates of children's epiphysis locking.
As shown in Figs. 1-3, the embodiment of the invention provides a kind of four side butterfly steel plates for the locking of children's epiphysis, packets
The steel plate ontology 1 that shape is in four side butterflies is included, is had between the steel plate body upper part 101 and the steel plate body lower part 102
Angle, is laid with the 4-6 threaded holes for being used to be fixedly connected screw 4 on the steel plate ontology 1, and the screw 4 with it is described
There is angle, angle is adjustable, preferably 4 screws, is equipped at the symmetrical centre of the steel plate ontology 1 between steel plate ontology 1
Location hole 3 and groove 6.
The shape of the steel plate ontology 1 of the invention is in four side butterflies, can effectively prevent the rotation of steel plate ontology.It is described
Location hole 3 plays the role of positioning, and guide pin passes through the location hole 3 on steel plate ontology of the invention, determines steel plate and children's epiphysis 5
Positional relationship.Recessed grain of the invention adapts to anti-rotational holder, and the groove 6 plays the work for preventing steel plate ontology 1 from rotating
With under the cooperation of anti-rotational holder, the location hole 3 and the groove 6 increase the holding of steel plate ontology 1 and can operate
Property.
Wherein, it is mounted on the screw 4 of the steel plate body upper part 101 and is mounted on the spiral shell of the steel plate body lower part 102
Nail 4 is not parallel mutually, increases the resisting pull out forces of the screw 4.
Wherein, the angle being mounted between the screw 4 of the steel plate body lower part 102 and the steel plate body lower part 102
In 105 ° -115 °, preferably 110 °.
Wherein, the angle being mounted between the screw 4 of the steel plate body upper part 101 and the steel plate body upper part 101
In 105 ° -115 °, preferably 110 °.
Wherein, the angle between the steel plate body upper part and the steel plate body lower part is in 155 ° -165 °, preferably
160°。
Steel plate of the invention in application process, under the cooperation by location hole 3, groove 6 and anti-rotational holder, incite somebody to action this
The steel plate ontology of invention is positioned on children's epiphysis 5, is turned at this point, the shape of the steel plate ontology can effectively prevent steel plate
It is dynamic.
After percutaneous plate of the invention to children's epiphysis 5, with the growth of children's epiphysis 5, pass through the steel plate ontology
The angle between angle and steel plate ontology 1 and screw 4 between top 101 and the steel plate body lower part 102 can elasticity
The epiphysis 5 of children is locked, temporarily blocks the growth of children's side seam epiphysis 5, correction has deformed limbs, while can also reduce
Epiphysis 5 grows the vertical stress generated to screw 4, reduces the risk of the fracture of screw 4.Steel plate of the invention is to children to because of bone
Cacomelia orthopedic effect is good caused by 5 dysplasia of epiphysis.
In above scheme, after the screw 4 is fixed on steel plate ontology 1, with the growth of children's epiphysis 5, pass through
Between angle and steel plate ontology 1 and screw 4 between the steel plate body upper part 101 and the steel plate body lower part 102
Angle can temporarily block the growth of children's side seam epiphysis 5 with the epiphysis 5 of elastic locking children, and correction has deformed limbs；Installation
The steel plate body upper part 101 screw 4 be mounted on the steel plate body lower part 102 screw 4 mutually it is not parallel, increase
The resisting pull out forces of the big screw；The design reduction growth of epiphysis 5 of steel plate and screw of the invention generates screw 4 vertical
Stress reduces the risk of the fracture of screw 4；Steel plate of the invention to children to because caused by 5 dysplasia of epiphysis limbs it is abnormal
Shape orthopedic effect is good, reduces the incidence of postoperative complications.
