Osteotomy device, belong to orthopedic medical device technical field.
Background technique
Knee joint osseous arthritis is the elderly's one of the most common type joint disease, and causes the elderly's lower limb disability
Main cause drastically influences the daily routines and quality of life of the elderly.Knee joint osseous arthritis refers to due to knee joint
A kind of chronic Bones and joints illness caused by cartilage degeneration, osteoproliferation is clinically mainly shown as gonalgia and not
With the dysfunction of degree, partially there are arthroncus, hydrops, joint space narrows, joint margins spur is formed for x-ray performance, soft
Osteosclerosis and cystis degeneration under bone.X-ray film has knee joint osseous arthritis shower about 60% in 55 years old or more crowds, wherein 35%--
50% has clinical manifestation.When gerontal patient's gonitis knee joint varus (turning up), stress concentrates on kneed inside (outside)
Part, and accelerate the degenerative change progress that on the inside of knee (outside) occurs, in this case, proximal ends of tibia osteotomy
Art is common therapeutic method of surgery, and this method opens up osteotomy gap (referring to Fig. 1) in proximal ends of tibia side first, then uses
Osteotomy gap is strutted and is fixed after width appropriate using bone plate by dilator, smooth with the posterior articular surface that ensures to heal,
Restore the lower limb line of force, avoid the occurrence of postoperative traumatic arthritis.It is found by a large amount of clinical practice, at present High Tibial Osteotomy
Existing main problem is: bone plate is generally plate armature, has a single function, and when operation stitches osteotomy first with dilator
Gap struts width appropriate, and plate fixation in osteotomy and then is removed dilator by stand-by screw.This synthetism mode
Not only complicated for operation, working efficiency is low, and during removing dilator, it is easy to because screw interporal lacuna is big, osteotomy is returned
The reasons such as bullet cause osteotomy gap to change, to reduce surgical quality.Thus, it is quite necessary to existing bone plate
It improves.
Summary of the invention

It is above-mentioned that there is the osteotomy device for strutting and fixing sutura function, it is further fixed on the turning handle of the rotating handle type dilator
The coaxial stabiliser bar with locating shaft.
Above-mentioned to have the osteotomy device for strutting and fixing sutura function, the depth for pushing away bone plate insertion osteotomy gap is 3
~5 millimeters, the angle for pushing away bone plate and sliding between push plate is 120 °~150 °.
It is above-mentioned that there is the osteotomy device for strutting and fixing sutura function, the sliding push plate and lengthening connecting plate and osteotomy to stitch
The corresponding position of gap is equipped with slit width Measurement scales.
Above-mentioned to have the osteotomy device for strutting and fixing sutura function, the fixed plate is equipped with pawl limit screw, institute
State the side that pawl limit screw leans against the separate rack gear of pawl.
The present invention utilizes by gear-rack drive, by the sliding push plate that pawl positions and struts sutura, not only easy to operate, fast
Victory, procedure efficiency are high, and since this osteotomy device is first fixed rear distraction sutura, can avoid screw interporal lacuna, osteotomy
The influence to osteotomy gap control precision such as rebound ensure that the treatment of Osteoarthritis to effectively increase surgical quality
Effect.

Specific embodiment
The present invention provides a kind of slide type osteotomy device, which not only has the function of fixed osteotomy, but also can have
Effect improves surgical quality and procedure efficiency.
Referring to Fig. 2~Fig. 8, the invention mainly comprises fixed plates 3, sliding push plate 4, rotating handle type dilator 5, limit screw 6
With pawl 7.Wherein, fixed plate 3, sliding push plate 4, limit screw 6 and pawl 7 are the devices for fixing osteotomy, and rotating handle type
Dilator 5 is an auxiliary tool, the only use when strutting sutura, and sutura is removed after strutting.
In figs. 3 and 4, fixed plate 3 is T-type plate, and the two sides of in-between straight-arm are equipped with straight 3-4, and two straight lines are sliding
Pawl shaft 3-2, dilator location hole 3-3 and set screw hole 3-5 are processed between slot 3-4, are additionally provided in fixed plate 3 more
A screw hole 3-1, for fixed plate 3 to be fixed on to treated shin bone or femur.
In fig. 5 and fig., the main body for sliding push plate 4 is rectangular slab, and the front end of rectangular slab, which processes, pushes away bone plate 4-2, rear end
Process rack gear 4-1.Two straight 3-4 being inserted into two sides of rectangular slab respectively after completion of processing in fixed plate 3
It is interior, then pawl 7 is mounted on pawl shaft 3-2 by torsional spring.The pawl point of pawl 7 is caught in rack gear 4-1 under the effect of torsion spring
Two teeth between, only allow a rack gear 4-1 unidirectionally move.
In figures 7 and 8, rotating handle type dilator 5 is made of locating shaft 5-1, gear 5-2, turning handle 5-3 and stabiliser bar 5-4,
Locating shaft 5-1 and stabiliser bar 5-4 coaxially to each other and is separately mounted to the two sides of turning handle 5-3, and gear 5-2 is fixed on locating shaft 5-1
On, the diameter of locating shaft 5-1 is slightly less than the diameter of the dilator location hole 3-3 in fixed plate 3.
It is of the invention use process is as follows:
It is placed on treated shin bone or femur after fixed plate 3, sliding push plate 4 and pawl 7 are assembled, and makes to slide push plate
The bone plate 4-2 that pushes away of 4 front ends is protruded into osteotomy gap 2, and then fixed plate 3 is fixed on treated shin bone or femur with screw
(as shown in Figure 9 and Figure 10).Then by the dilator location hole 3- in the locating shaft 5-1 insertion fixed plate 3 of rotating handle type dilator 5
In 3, hand steered live in a stabiliser bar 5-4 makes gear 5-2 and rack gear 4-1 positive engagement, another hand operates turning handle 5-3, makes gear
5-2 slowly rotates, and gear 5-2 driving sliding push plate 4 is moved along straight 3-4, pushes away bone plate 4-2 by 4 end of sliding push plate
Osteotomy gap 2 is supportted greatly.After osteotomy gap 2 reaches the width of setting, remove rotating handle type dilator 5, at this time slide push plate 4 by
Pawl 7 positions, and cannot move backward, and pawl 7 fails in order to prevent, pawl limit screw 6 can be screwed in set screw hole 3-5
In (as is illustrated by figs. 11 and 12).
It, can be in the fixed lengthening connecting plate 4- in the front end of sliding push plate 4 in order to be reliably fixed osteotomy referring to Figure 13 and Figure 14
3, after osteotomy gap 2 reaches the width of setting, connecting plate 4-3 will be lengthened with screw and is connected to treated shin bone or femur
Together, osteotomy device entire in this way can be stronger.In order to facilitate the adjusting in osteotomy gap 2, in sliding push plate 4 and can also add
Slit width Measurement scales 4-4 is arranged in position corresponding with osteotomy gap 2 on long connecting plate 4-3.
Compared with traditional osteotomy device, operation of the present invention step is few, can save operating time, improves procedure efficiency, and
The degree of regulation in osteotomy gap is high, and surgical quality can be improved, guarantee the therapeutic effect of Osteoarthritis.
