The first sliding block 322 and the second sliding block 323 are connected with, first sliding block 322 is fixedly installed rotatable second connecting seat 42,
Second sliding block 323 is fixedly installed rotatable 3rd connecting seat 43, and second connecting seat 42 is removably connected with
Two parallel bars 332, first parallel bar 331 have been rotatably connected first level bar with 332 top of the second parallel bar
341, second parallel bar 332 is provided with the 4th connecting seat 44, the 3rd connecting seat 43 and the 4th connecting seat 44 it
Between be removably connected with rotatable locating rod 51, be rotatably connected draw bar 61 on the second connecting rod 312, described first
341 slidable connection of horizon bar has guiding piece 62, and the guiding piece 62 is provided with L-shaped locating piece 621, the guiding piece 62 and institute
It states draw bar 61 to connect by metal cables (not shown), is provided with and is used to support between two first parallel bars 331
The fabric or metallic rod of thigh are provided with the fabric for being used to support shank between two first level bars 341.
The following detailed description of the operation principle of the draft gear provided by the utility model for fracture of tibia operation.When
It needs when carrying out tibial surgical to the shank of patient in operating table (not shown), first can select to close according to the build of patient
The suitable first connecting rod 311 and the second connecting rod 312 connects two base rods 32, so as to ensure described in two
Base rod 32 can be located at the both sides of patient thigh when being placed on operating table, so also mean that in thigh projecting direction
Structural member (such as second parallel bar 332 and described first level bar 341) can positioned at patient thigh both sides (while
Mean that the both sides positioned at patient's shank), so as to can ensure that comfort that patient uses and ensure will not be to surgical procedure
In ray equipment perspective cause to interfere, so as to can be selected the high metal material of intensity prepare the utility model for tibial bone
Roll over the structural member of the draft gear of operation.
The first connecting rod 311 and the second connecting rod 312 can be pairs being inserted by plug in the base rod 32
Jack is answered, so easy to disassemble and replacement, certainly, the first connecting rod 311 and the second connecting rod 312 can also utilize weldering
The telescopic rod (such as self-locking pneumatic bar) that modes are fixedly connected between two base rods 32 such as connect, as long as can be convenient for
The distance between two described base rods 32 of adjustment.
When patient thigh rests on the fabric set between two first parallel bars 331 or metallic rod (is not shown in figure
Go out) when, patient's shank is rested in the fabric (not shown) between two first level bars 341, due to described
One parallel bar 331 and second parallel bar 332 can synchronous rotary, therefore, patient is adjusted rotating first parallel bar 331
During the flexion angle of thigh and shank, the holding of patient's shank can be made horizontal.Between two first parallel bars 331 and two institutes
It can be the fabrics such as bandage or canvas to state the fabric between first level bar 341, can provide certain support strength and avoid
Ray equipment perspective during operation is impacted.Certainly, since surgical procedure needs to carry out traction drawing to patient's shank
It stretches, therefore, Demountable metallic bar (not shown) is may also set up between two first parallel bars 331, so as to logical
It crosses raising and rests against rigidity to ensure the positioning in drawing process to thigh.
First connecting seat 41, second connecting seat 42, the 3rd connecting seat 43 and the 4th connecting seat 44
Bulb bearing is may each be, can so ensure that each connecting seat is capable of providing larger angle rotatable scope.
First sliding block 322 can slide on first guide rail 321 and pass through bolt (not shown) and lock, this
Sample can provide support according to the first level bar 341 of the size selection different length of patient's shank.
Second sliding block 323 can slide on first guide rail 321 and pass through bolt (not shown) and lock, this
Sample is after first parallel bar 331 is adjusted in place with second parallel bar 332, by locking second sliding block 323, i.e.,
The position of first parallel bar 331 and second parallel bar 332 is fixed using the locating rod 51.
As shown in Fig. 2, the first level bar 341 may be provided with dovetail slideway, the guiding piece 62 may be provided with pair
The swallow-tail form guide groove answered so can ensure that the guiding piece 62 can be slided along the first level bar 341, so as to adjustable
The position assurance patients feet of the guiding piece 62 is located at the L-shaped locating piece 621 and is bonded.The L-shaped locating piece 621 can be set
The woven belt (not shown) of binding patients feet is useful for, patients feet can be so firmly fixed to the L-shaped and determined
On the block 62 of position.
The guiding piece 62 is connected with the draw bar 61 by metal cables (not shown), firm in patients feet
After being fixed on the L-shaped locating piece 62, by rotating the draw bar 61, you can so that the guiding piece 62 is along described
One horizon bar 341 slides, and so as to implement stretching and drawing to patient's shank, shin bone fracture location also can just be made to reset alignment.
The draw bar 61 can be used ratchet structure with the second connecting rod 312 and be connected, so can be after traction in place really
Guarantor will not occur to spring back displacement.
The draw bar 61 can connect metal cables in middle and lower part, can so provide the larger arm of force to operator, so as to
Substantially reduce physical demands of the operator when carrying out stretching and drawing.
First parallel bar 331 and second parallel bar 332 may be provided with U-lag, and the first level bar 341 can
It is provided with to be inserted into the auricle of U-lag, so using pin by the first level bar 341 and first parallel bar
331 and second parallel bar 332 be rotatably connected.Likewise, the locating rod 51 may also set up U-lag, and described
Four connecting seats 44 can be set to be inserted into the auricle of U-lag, so also can easily pass through the pin locating rod
51 and the 4th connecting seat 44 be rotatably connected.
Draft gear provided by the utility model for fracture of tibia operation, easy to operate convenient for assembling, support is steady
It is fixed, the workload and labor intensity of medical staff are greatly reduced, and can ensure shin bone fracture location in surgical procedure well
Reset alignment.
