Description
Technical field
The present invention relates to a kind of aided measurement devices to belong to doctor more particularly to articular ligament injuries auxiliary examination device
Learn measuring appliance technical field.
Background technique
With "sport for all", the rise of nationwide fitness programs and universal, joint motions damage includes that ligamentous injury of knee joint, wrist close
It is increasing to save ligament injury, ligament injuries of ankle joint, ligament of shoulder joint damage etc..Ligament injury is clinical relatively conventional movement
Damage easily influences the stability in joint, leads to a series of sequelae, and some patientss often because of outpatient service mistaken diagnosis or are treated not in time, indulged in
Accidentally best occasion for the treatment, rehabilitation effect are good.
Current checkout and diagnosis means include side stress test, drawer test, pivot shift test, patient from master trip and drawing
Ke Man (Lachman) test.These detection means accuracys are poor and judgement is more subjective, while being easy tough to what is damaged
Band causes secondary injury.Either front drawer test or Lachman test, all exist and miss because applying due to inspection person's dynamics is different
The problem of difference, i.e., same patient can obtain different conclusions in different physicians physical examination.
Pure mechanical size measurement is relatively primitive, and measurement inaccuracy also be easy to cause and fails to pinpoint a disease in diagnosis or mistaken diagnosis.It and is not special
Door is that articular ligament injuries are detected and developed, and specific aim is not strong.In practical physical examination, clinician is only capable of obtaining substantially with feel
Qualitative judgement, it is difficult to accomplish more accurate quantitative check.Advanced CT or nuclear magnetic resonance check (MRI) are although detection accuracy
Relatively high, but equipment is prohibitively expensive, testing cost is higher, and burden of patients is heavier, and it is this kind of big not to be that every hospital is all equipped with
Type high end equipment.It on the other hand, cannot after some patients are because of implantation heart metallic support, pacemaker or internal fixation material
Or be not suitable for carrying out CT or MRI inspection, therefore the objective basis of ligament injury can not be obtained.Being badly in need of a kind of measuring device can provide
Objective determination is as a result, instruct clinical position.
Patent CN201720340045.2 provides a kind of knee-joint cross ligament damage measuring device.But this is specially
Benefit has the following problems: 1) using original mechanical scale measurement as inspection foundation；2) before application range is only limitted to knee joint
Cruciate ligament inspection is not suitable for other ligaments (posterior cruciate ligament of knee, interior lateral collateral ligament etc.) of knee joint, is less suitable for
The inspection of other articular ligaments.
When much articular ligament injuries suspected patient is to hospital, part doctor is due to lacking the tool accurately checked, no
Patient is just advised to carry out CT or nuclear magnetic resonance check after training physical examination or simple progress physical examination, by the property made a definite diagnosis that price is relatively expensive
Diagnostic techniques causes unnecessary society, economy and medical resource waste as initial screening means.In addition, even if part
Young doctor has carried out training physical examination, but because correctly cannot skillfully grasp articular ligament injuries physical examination method, to light moderate lesion
Patient has carried out early stage negative exclusion, and then delays treatment.On the other hand, after ligament injury operation is repaired, it is also desirable to a kind of
Tool carries out preoperative with postoperative measurement of comparison, the effect and quality performed the operation with objective data judge.Therefore compel the joint that is essential at present
Improvement training physical examination based on quantitative biomethanics inspection, pass can accurately be measured by shirtsleeve operation by how designing one kind
The degree of injury of surrounding ligaments is saved, and can be suitably used for the measuring tool of all kinds of articular ligament injuries inspections of human body, becomes urgent need solution
Technical problem certainly.
