The clinical basic of the measurement of row biomechanicss and analysis is reset into maneuver, causes the technology secular stagnation in experiential operating rank
Section, it is impossible to form standardized working specification, cause quality of reduction uneven, success rate go fromes bad to worse, increasing trouble
Person is improper due to resetting, and is forced to be treated surgically.Thus cause nearly 10,000,000,000 extra medical expense every year, occupy greatly
Medical resource, and heavy financial burden is caused to national governments and patient individual.This trend also runs counter to " minimally invasive or even nothing
Wound treatment " becomes the core concept and historical development trend of current disease treatment.To radius far-end fracture reset and device for measuring force
Exploitation, the success rate of traditional method reset can be greatly improved, reduce the ratio for receiving operative treatment, a large amount of so as to save
Medical expense.On the other hand, the medical development trend of non-invasive therapy has been also conformed to.
Radius far-end fracture reset and device for measuring force are studied, by installing " mechanics sensor " and " angle positioning additional
The components such as device " obtaining key mechanics parameter and the related angle of traction and reset force, are the standardization of the reduction of the fracture, quantitative
Change, precision operation provides theoretical foundation and approach in the cards.Additionally, the research also helps exploration proposes a set of being based on
The standardized repositioning method of the product and step, to improve quality of reduction and promote resetting technique standards and norms process,
Allow more doctors skillfully to grasp this technology, so as to reduce the Proportion of patients of operative treatment, significantly reduce medical treatment cost, every year
Several hundred million first medical expenses can be saved.

Information such as drift angle, hauling distance, and these joint parameters rarely have research at present and report, are the standardization of the reduction of the fracture, quantitative
Change, precision operation provides theoretical foundation and approach in the cards.
(4) present invention is easy to operate, and completely compatible traditional traditional Chinese medical science bonesets and doctor trained in Western medicine reduction of the fracture technology, and is particularly suitable for
One man operation, learning curve are short.And conventional radius far-end fracture traditional method resets, many doctors and assistant is needed to grasp simultaneously
Make, time-consuming effort, reset effect vary, it is difficult to make extensive patients and family members' satisfaction.The present invention can aid in doctor and improve
Reset success rate, when technology maturation, is suitable for clinic spread.
(5) beating after the presence without prejudice to doctor of forward and backward alternative expression arm-supporting splint system of the invention is to patient's manual reduction
Gypsum Fibrosum is operated.When keeping the wrist palm to incline with chi off normal, the forearm of patient must have a fixed fulcrum to patient.But the fulcrum
Presence, it will affect doctor to carry out the operation of plaster fixing to the forearm of patient.So the forward and backward alternative expression arm-supporting splint of design
System, alternately provides fulcrum by forward and backward alternative expression arm-supporting splint system, and being easily accomplished doctor carries out Gypsum Fibrosum to patient forearm
Fixed operation.
(6) present invention, is made whole from the material that some can be had an X-rayed under C arm X-ray machines by the optimization to some parts
Reseting procedure can be had an X-rayed under monitoring in C arms X-ray machine and carry out, and allow C arms X-ray machine clearly positive and lateral can have an X-rayed patient
Wrist, to doctor's Real Time Observation patient reset effect provide facility.
