Description
Technical field
The present invention relates to medical operating assistive device field more particularly to a kind of knee joint x-ray image detection device and its
Application method.
Background technique
In kneed surgical procedure, often need to close the knee joint side coil structural stress testing experiment and knee of patient
The drawer stress test test of section front and back.Wherein, in knee joint side coil structural stress testing experiment: examining shank with respect to thigh
It after surveying the deflection that force in plane keeps certain, is taken pictures, while is assisted using line of force bar as shooting by C-arm x-ray machine
The reference analysis of film afterwards, and the test of drawer stress test also needs to exert a force before and after knee joint.
Currently, needing several medical staff to live shank is made to exist with respect to thigh with hand steered when C-arm x-ray machine is taken pictures
Detection plane keeps certain deflection, i.e., keeps patient to take pictures position without related para-operational device, meanwhile, line of force bar can only
The side of patient legs is placed into as reference, or is suspended the leg top of remaining patient by medical staff.
Above-mentioned there are many defects by the way of manually keeping patients surgery position: 1, increasing the labour of medical staff
The quantity of intensity and surgical staff；2, medical staff is due to needing that same posture is kept to be easy to produce fatigue for a long time, and then leads
It causes to operate unstable influence operation；3, medical staff is highly susceptible to the radiation of X-ray, this to the injury of medical staff compared with
Greatly；4, line of force bar cannot steadily place the surface with leg, artificially there is shake, cause to deviate best placement, lead
Cause cannot refer to the film of subsequent shooting；5, in ligamentous injury of knee joint detection, need to carry out the survey of front and back drawer stress
It has a try and tests, generally use the mode of nuclear magnetic resonance equipment detection expensive, high-definition, still, current middle and small scale
Hospital lack the economic nuclear magnetic resonance equipment of such nuclear magnetic resonance equipment or part can not shooting clear photo, and then cause
Treatment and detection difficult.
