Description
Technical field
The utility model relates to artificial knee joint replacement field more particularly to a kind of operation joint space measuring instruments.
Background technique
Work knee replacements are just being widely used in congenital abnormality, wound, disease or degenerative arthritis etc..Its energy
It is ailing effectively to eradicate advanced stage knee joint, greatlys improve the quality of life of patient.This total knee replacement
Gap when most importantly correctly measuring lower limb buckling when operation and stretching.It needs to accurately measure kneed when operation
Buckling gap and stretching, extension gap, and in the buckling gap and stretch state of the measuring device in gap between knee joint
Under, it needs to maintain kneed gap with certain power.If existing device, which has a problem in that, improves accuracy, it is difficult to
Gap is maintained to reduce accuracy if gap can be maintained.If the gap of the artificial knee joint cannot accurately be measured,
In the state of the artificial knee joint replacement to human body, gap imbalance, joint instability, to occur will occur in knee joint
Arthralgia, insufficiency, even Prothesis failure.
Utility model content
The purpose of this utility model is to provide a kind of operations of precise measurement knee space while maintaining gap
With joint space measuring instrument.
To achieve the above object, the operation of the utility model joint space measuring instrument, it is characterised in that: including measuring hand
Handle, transmission rod and measurement fixed block, the measurement handle inner is hollow, and center is equipped with a regulation tie point, tie point two sides
It is respectively fixedly connected with a spring, the other end of spring is separately connected transmission rod, and the transmission rod is respectively from the two of measurement handle
End is stretched out outside measurement handle, and the measurement fixed block is removably attachable on transmission rod.
Further, measurement handle front transmission rod position is equipped with transparent scale window, and dial window is equipped with graduation apparatus,
The transmission rod is equipped with tuning drive gear.
It further, further include buckle and card slot, one end that transmission rod stretches out measurement handle is arranged in the buckle, described
Card slot setting is adapted on measurement fixed block with the buckle on transmission rod.
Further, the measurement fixed block is thickness difference dimensions.
Preferably, the measurement fixed block is a different size with a thickness of 2mm-10mm, every difference 1mm.
The present apparatus mainly has the advantage that
(1) design mutually assembled using measurement fixed block with measurement handle, measurement fixed block can be replaced flexibly, a measurement
Handle can mating multiple specifications measure fixed blocks, be easy to use, while saving memory space；
(2) measurement fixed block is stretched into dynamics and is converted into intuitive visual measurement data, facilitate doctor's clinic accurate judgement.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is buckle structure schematic diagram on transmission rod.
Fig. 3 is fixed-block-architecture (FBA) schematic diagram.
In figure: 1 is measurement handle, and 2 be transmission rod, and 3 be spring, and 4 be fixed connection point, and 5 be dial window, and 6 be that measurement is solid
Determine block, 7 be card slot, and 8 be buckle.
Specific embodiment
As shown in Figure 1, the operation of the utility model joint space measuring instrument, mainly by measurement handle 1,2 and of transmission rod
It measures fixed block 6 to form, wherein measurement 1 boring of handle, both ends open, measure center in the cavity of handle 1 and be equipped with
One fixed connection point 4, the two sides of fixed connection point 4 are separately connected a spring 3, the both ends of two springs 3 respectively with power transmission
Bar 2 connects, 2 one end connecting spring 3 of transmission rod, and the other end is stretched out from the aperture position at measurement 1 both ends of handle respectively, measures handle
12 position of transmission rod is dial window 5, and dial window 5 is equipped with pulling force scale, and transmission rod 2 corresponds to 5 position of dial window and is equipped with quarter
Spend pointer.
Stayed mast stretches out one end connection buckle 8 of measurement handle 1, while being equipped with and 8 phase of buckle on measurement fixed block 6
The card slot 7 of adaptation, measurement fixed block 6 have the various sizes of specification of thickness, with a thickness of 2mm-10mm, wherein every difference 1mm is one
A different specification, as shown in Figure 2.
In actual use, the measurement fixed block 6 of suitable dimension is selected according to different joint spaces first, and will surveyed
The card slot 7 of amount fixed block 6 is connect with the buckle 8 of transmission rod 2, as shown in Figure 3.Then measurement fixed block 6 is put into the pass stretched
It in internode gap, stretches out, passes through the pulling force scale under the pulling force calibration record on measurement handle 1.Then measurement is fixed again
Block 6 is put into bent position joint space, and records lower pulling force scale.
After completing measurement, the data measured more twice, if two data are consistent, it can be determined that Neck Flexion and Extension joint
Gap it is consistent.
Above-described specific embodiment has carried out further the purpose of the present invention, technical scheme and beneficial effects
It is described in detail, it should be understood that the foregoing is merely a specific embodiment of the invention, the guarantor that is not intended to limit the present invention
Range is protected, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should all be contained in this hair
Within bright protection scope.
