Specific embodiment
The utility model is described in detail with reference to the accompanying drawing.
In figure, the device for Convenient table in replacement knee in arthroplasty includes leg-clamping devic, leg support device, lifting device；
Wherein, the leg support device is used to support leg, and installs fixture on the leg support device, and the fixture is solid for being clamped in
On earnest, leg support device is fixed, so that it will not generate to shake.
The leg-clamping devic is mounted on the side of leg support device, and effect is the two sides for clamping leg；The leg
Rest device, leg-clamping devic jointly fix leg, and when operation, leg will not be tampered；The lifting device is mounted on leg support
The lower section of device, the height of lifting device the adjustment leg-clamping devic and leg support device, to be applicable in the leg of different length, flexibility
It is high.
The specific structure of each component is described below:
The leg support device includes pedestal 1, support column 2, guiding axis 3, support rod 4；Sliding slot is set on the pedestal 1, institute
Stating sliding slot is open-work, and the support column 2 is mounted on the centre of pedestal 1, supports support column 2 by pedestal 1；The support column 2
Axial direction pass through guiding axis 3, guiding axis 3 is used to install the swing arm 6 of leg-clamping devic；Wherein, the one or both sides peace of pedestal 1
Support rod 4 is filled, the fixture is mounted on support rod 4, and whole device is fixed on the T-type side rail of operating bed by fixture.
The leg-clamping devic includes 5, two swing arms 6 of two clamping plates, a block pressur plate 10；Two swing arms 6 are located at support column 2
Two sides, and guiding axis 3 passes through the lower end of two swing arms 6；One piece of clamping plate 5 is installed in the upper end of the swing arm 6 respectively, clamping plate 5 with
The side of leg is contacted, and the medial surface of clamping plate 5 is arcuate structure, to adapt to the curve of leg, and the area of clamping plate 5 compared with
Greatly, when clamping is exerted oneself, patient will not feel good.
It is preferred that support column 2 lower end be arranged a groove, pressing plate 10 pass through support column 2 groove and be adapted to be accommodated in cunning
In slot, meanwhile, the sky formed between the lower end groove for being accommodated in support column 2 being also adapted to and pressing plate 10 of two swing arms 6
In, so that swing arm 6 is fixed；The setting of pressing plate 10 is understood in subsequent descriptions and is retell mainly for positioning two swing arms 6
It is bright.
The bottom mating of sliding slot has bottom plate 22, and the bottom plate 22 is fixed on the bottom of pedestal 1 by connector, such as screw
Portion, bottom plate 22 provide basis for the force of pressing plate 10；The bottom plate 22 setting spiral shell corresponding with the bottom middle position of pressing plate 10
Wire hole one, one inner button installation and adjustment screw rod 1 of screw hole can jack up pressing plate 10 during one 7 knob of adjusting screw rod
Come；The two sides of the screw hole one, the corresponding setting screw hole two on bottom plate 22 and pressing plate 10 simultaneously, the screw hole
The position of the installation and adjustment screw rod 2 11 being adapted in two, screw hole two is corresponding with the position that pressing plate pushes down swing arm end simultaneously；
The bar portion of adjusting screw rod 2 11 is socketed spring 12, and after pressing plate 10 is come up by the top of adjusting screw rod one, the lower end of swing arm 6 is filled in
In space between pressing plate 10 and support column 2, adjusting screw rod 2 11 exerts a force later, and the lower end of swing arm 6 is held out against by pressing plate, thus will
The position of swing arm 6 is fixed, and so as not to voluntary activity, realizes the fixation of 6 position of swing arm.
The pressing plate 10 includes plate-like body, and the upper surface of plate-like body is arcuate structure, and plate-like body adaptation is located
In sliding slot, the centre of the plate-like body has a limiting slot, the bottom of the pedestal 1 can holding in limiting slot, limitation
The axial activity of pressing plate.
It is preferred that the end outward bending of swing arm 6 has a flanging, flanging is inserted into the space between support column 2 and pressing plate 10,
It is exerted a force by adjusting screw rod and compresses flanging.
When needing to loosen swing arm 6, adjusting screw rod 2 11 is unclamped, spring 12 springs back, will push away under adjusting screw rod two, press simultaneously
Plate 10 follows adjusting screw rod two to fall, and swing arm loses oppressive force and can arbitrarily adjust position or unload.
Swing arm 6 mainly undertakes the effect of leg-supporting, and the weight of leg can all be implemented on swing arm 6, therefore swing arm 6
The stability of position is extremely important, and in order to further fix the position of swing arm 6, the outside of swing arm is installed respectively on guiding axis 3
Structure is seized, the position of swing arm 6 is locked, is fixed by the structure that seizes.
Band-type brake structure includes locking nut 8, and screw thread, the spiral shell of locking nut 8 and guiding axis 3 can be set in the both ends of guiding axis
Line cooperates knob, so that the position of swing arm 6 is locked, is fixed by locking nut 8.
Locking nut 8 is loosened because of external force in order to prevent, in the lower end installation locking handle 9 of swing arm 6, the locking screw
Groove is set on female surface, the set lever 9 can be pressed in the groove of locking nut, thus by the position of locking nut 8
Set fixation.
Transfer is installed, the bottom of the clamping plate 5 includes a downwardly convex hemisphere between the clamping plate 5 and swing arm 6
Hemispherical groove is arranged on the convex block 13 in shape convex block 13；The transfer includes two hemisphere, handle 14, nut 15, spiral shell
Bar 16；Described two hemisphere are respectively outer hemisphere 17, interior hemisphere 18, and what the interior hemisphere 18 was adapted to is fitted in the hemispherical of convex block
In groove, what the convex block 13 was adapted to is fitted in the groove of outer hemisphere 17, and the convex block 13 can be centered on outer hemisphere 17
It is rotated；16 free end of screw rod sequentially passes through the center of interior hemisphere 18, convex block 13 and outer hemisphere 17, the spiral shell across center
Connecting handle 14 and nut 15 are successively covered on bar, the head of screw rod 16 is located on the end face of interior hemisphere 18 as limitation end.It is preferred that hand
Arc groove is also provided on handle 14, what the outer hemisphere 17 can be adapted to is located in arc groove, when needing strap side
To when, the component on screw rod 16 is successively locked by nut 15.
When needing to adjust the angle of clamping plate, it is movable on support column 2 that leg first rides over, and finds the angle of oneself needs,
Transfer can follow the movement auto-steering of leg, and after angle is adjusted, locking nut fastens swing arm, and handle 14 is locked, and turn
It is no longer arbitrarily rotated to device, when needing to adjust steering again, release handle repeats above-mentioned step, until finding conjunction
Suitable angle.
The fixture includes band-type brake 19, side rail fixture 20, and handle 21 and locking device are installed on band-type brake 19, and handle can incite somebody to action
Locking device is tightened and is loosened, and the band-type brake 19 and side rail fixture 20 are all mounted on support rod 4, and the side rail fixture 20 is installed
On the side rail of operating bed, particularly when rail fixture 20 is caught in the T-type of operating bed on rail, so that pedestal be fixed, keep away
The shaking of leg support device when exempting from deep.Since band-type brake 19 can work as needs on rail while rail fixture 20 is locked at operating bed
When adjusting the height of leg support device, band-type brake 19 is unclamped using handle 21, leg support device is slided along support rod 4 later, works as height
After degree determines, by handle locking band-type brake 19, so that the height of leg support device be fixed.
The above is only the preferred embodiments of the utility model embodiment, are not intended to limit the utility model implementation
Example, all within the spirit and principle of the utility model embodiment, any modification, equivalent replacement, improvement and so on should all wrap
It is contained in the protection scope of the utility model embodiment.
