Description
Technical field
The present invention relates to a kind of orthopedic medical device more particularly to a kind of novel orthopaedics steel plates promoting union.
Background technology
Currently, the locking and pressurizing steel plate combination intramedullary nail used uses, have wound small, destruction of bone is few, angle stabilization
The good advantage of property.Conventional use of Lucking compression plate has wound small, the good advantage of stability.But when treating limbs fracture
Can only in art disposable loaded reset, due to locking nail fix after, screw is opposing stationary relative to fracture end, cannot to fracture
Hold persistent pressure.This is easy for after occurring fracture end bone information after surgery, bone nonunion caused by fracture gap increases occurs.
Therefore, locked pressurized bone plate can only disposably be pressurizeed in art, it cannot be guaranteed that after the bone information of postoperative fracture end
The problem of gap repressurization of appearance is closed, is easy to happen bone nonunion.
In order to solve above-mentioned clinical problem, this just needs a kind of " controllably continuing locking compress Medical orthopedic steel plate ", makes bone
End locking steel plate Ineffective internal fixation is rolled over, does not change locking steel plate stability, fracture is reached by own body weight and muscular contraction force
End realizes that the persistent pressure of controllable pressurization distance reduces bone nonunion to promote fracture end to heal.
Invention content
Controllably continuing locking compress Medical orthopedic steel plate it is an object of the present invention to provide a kind of, is not changing original locking
Under the premise of steel plate stability, the persistent pressure of controllable pressurization distance is realized by own body weight and muscular contraction force, promotes bone
End healing is rolled over, bone nonunion is prevented.
To achieve the above object, the technical solution adopted by the present invention is：
A kind of controllable persistently locking compress Medical orthopedic steel plate, including：Steel plate, screw, steel plate upper and lower ends are equipped with more spiral shells
Nail, wherein all screws of one end or whole screws on steel plate pressurize cushion block on pressing sliding groove by sliding, sliding
Pressurization cushion block is detachably connected with screw, and pressing sliding groove is along steel plate genesis analysis；After sliding pressurization cushion block is installed in place, sliding adds
Pressure pad block has longitudinal glade plane space on pressing sliding groove.
Controllably continue locking compress Medical orthopedic steel plate according to described, screw cap is threaded, and screw cap is threadedly coupled peace
On sliding pressurization cushion block.
Controllably continuing locking compress Medical orthopedic steel plate according to described, sliding pressurization cushion block left and right side is inclined-plane,
Its upper and lower end face is arc surface；Pressing sliding groove is equipped with side compatible with sliding pressurization cushion block and end face, pressing sliding groove side
Length is more than the length of sliding pressurization cushion block side.
Controllably continue locking compress Medical orthopedic steel plate according to described, steel plate both ends are distributed with 3-5 screw, wherein one
Pressing sliding groove is distributed in end, and screw mounting hole is distributed in the other end.
Controllably continue locking compress Medical orthopedic steel plate according to described, steel plate both ends are distributed with 3 screws.
Controllably continue locking compress Medical orthopedic steel plate according to described, the glade plane space of the sliding pressurization cushion block is 1-
6mm。
It is an advantage of the invention that:
1. the configuration of the present invention is simple, convenient to carry out.The original screw hole in one end of steel plate need to be only changed to pressurization and slided by the technical program
Slot, screw are mounted on sliding pressurization cushion block；Sliding pressurization cushion block can be slided freely up and down along pressing sliding groove.Steel plate is installed
When, all sliding pressurization cushion blocks should be mounted on pressing sliding groove distal end, and sliding pressurization cushion block end face and pressing sliding groove end face are close
Contact.That one end far from fracture site on so-called distal end, that is, pressing sliding groove.As shown in figure 5, in surgical procedure, take one in art
Secondary property loaded reset, using Interal fixation；It is postoperative there is fracture end bone information after, musculature pulling force or body gravity pressurization make
Under, sliding pressurization cushion block will slide to fracture site.
2. using the technical program, post-operative recovery is good.Present invention preserves locking steel plates to have wound small, blood supply damage
Few, the good advantage of stability improves the shortcomings that it is unable to fracture end dynamic pressurized, and allows fracture end pressurization distance root
According to fracture end reduction situation, maximum pressurization distance is set in advance.The stability of fracture end and the length of bone had both been maintained in this way,
It in turn ensures the enough stress stimulations of fracture end, and then promotes union.

Specific implementation mode
The present invention will be further described by 1-6 below in conjunction with the accompanying drawings.
Present invention preserves locking and pressurizing bones plate to have wound small, and destruction of bone is few, the good advantage of angle stability.This
Inventive technique scheme locks the design of nail hole by improving, and improves the shortcomings that it is unable to fracture end dynamic pressurized, makes fracture end
Maximum pressurization distance can be set in advance according to fracture end situation in distance of pressurizeing, to ensure that fracture end continue controllably plus
Pressure.Not only promote fracture end to heal, but also avoid the excessive cripetura of limbs, and function effect occur.The present invention is by technical side below
Case realizes above-mentioned function.
The present invention controllably continuing locking compress Medical orthopedic steel plate, including steel plate 1, screw 3, about 1 steel plate as a kind of
