Description

A kind of knee joint stably measured instrument

Technical field

This utility model relates to medical device technical field, is related specifically to a kind of knee joint stably measured instrument.

Background technology

Knee-joint cross ligament damage is the most relatively conventional athletic injury, in the past only by clinical training body Inspection and imaging examination diagnose, and this method often lacks the quantizating index that can compare and add up, thus easily causes Fail to pinpoint a disease in diagnosis or mistaken diagnosis.Furthermore while the reparation of anterior cruciate ligament or reconstruction operations have become ripe, but the stability of postoperative ligament is entered Row quantitative evaluation still lacks a kind of effective method.For a long time, the KT1000 knee joint the most always used stably is surveyed Amount instrument, although approved the most in the industry, but there is also some problems: 1, non-telescoping regulation, it is impossible to be installed on not the same year With the patient of age and different lower-leg length, especially it is unsuitable for child patient；2, volume large and bulky, not readily portable, no Adapt to patient examination；3, price comparison is expensive, and needs import.Therefore these shortcomings all cannot meet clinical needs.Research and development one Telescopically adjustable, it is possible to be installed on the patient of all ages and classes and different lower-leg length simple and light, take the most with oneself It is firm with human contact's end comfortable that band is applied to patient examination, cheap, easily popularization, the knee joint that accuracy of measurement is high Stably measured instrument, is the art task of having needed.

Summary of the invention

The purpose of this utility model is to provide a kind of simple and light, is easily carried and human contact's end is firm easypro Suitable, cheap, accuracy of measurement is high, it is adapted to be mounted to all ages and classes and knee joint that different lower-leg length patients use is stable Measuring instrument.

In order to achieve the above object, this utility model following structure of employing: a kind of knee joint stably measured instrument, by arch torr Frame, the most glutinous binder, displacement impression dish, expansion link with a scale, external thread sleeve, nut, fixing screw and the most glutinous binder form, its Feature is: arched planes protruding in the middle part of steel plate arcuate cradle is provided with two uniform vertical through hole, and external thread sleeve passes One through hole, is clamped arcuate cradle by two nuts after sleeve pipe two ends screw in sleeve pipe respectively, and the circular displacement impression face of trying to get to the heart of a matter is Plane, the vertical fixing band in center scale expansion link above displacement impression dish, the expansion link other end slides through in external thread sleeve Forming free end, circular displacement is experienced plane of trying to get to the heart of a matter and is in same plane, arcuate cradle with base angle, arcuate cradle two ends lower plane On base angle, two ends, planar screw fixes the most glutinous binder of bar shaped of certain length, thus constitutes a kind of knee joint stably measured instrument.

Scale on described expansion link, its longitudinal extent is 30mm, and scale intermediate value is parallel to external thread sleeve top End, scale interval value is 1mm.

This utility model applies scalable high intensity arch steel bracket as main body, saves KT1000 knee joint and stably surveys The shell that amount instrument is very large, simple and light；After the base angle at bracket two ends carries out build adaptive processes, fixing certainly sticking is stretched tight respectively Band, firm fixing after patella front and distal tibia front are wound around, add the comfortableness of patient, on steel plate arcuate cradle Two through holes, can be respectively mounted displacement impression dish to adapt to the needs of the different long patient of lower limb.

During use, patient goes down on one's knees 30 degree and fixes measuring instrument, a hands immobilized patients foot, is placed in tibia with another hands Near-end rear, pushes away the most maximum manually position of proximal tibia before initial position, and impression dish can be tied with tibia in conjunction with expansion link with a scale Joint reach and wriggle up and down, read shift value by exposing scale on expansion link surface, external thread sleeve top, by than Relatively suffer from strong side reading difference, understand Ipsilateral and strong side slackness difference, it is judged that its knee Stability.

This utility model is simple and light, is easily carried firm with human contact's end comfortable, cheap, measurement standard Exactness is high, and the patient being adapted to be mounted to all ages and classes and different lower-leg length carries out knee Stability measurement, has reached invention Purpose.

Detailed description of the invention

Further illustrating this utility model below in conjunction with the accompanying drawings, Fig. 1 and Fig. 2 shows structure of the present utility model, one Plant knee joint stably measured instrument, by arcuate cradle 1, the expansion link 3 of displacement impression dish 2, with a scale 4, external thread sleeve 5, nut 6, fixing screw 7 and the most glutinous binder 8 form, and arched planes protruding in the middle part of steel plate arcuate cradle 1 is provided with two uniform hanging down Clear opening 9, external thread sleeve 5 is through a through hole 9, by two nuts 6 gripping bow after sleeve pipe 5 two ends screw in sleeve pipe 5 respectively Shape bracket 1, circular displacement impression dish 2 bottom surface is plane, and the displacement impression dish 2 vertical fixing band in center above carves the degree expansion link of 4 3, expansion link 3 other end forms free end, circular displacement impression dish 2 baseplane and arch torr in sliding through external thread sleeve 5 Base angle, frame 1 two ends lower plane is in same plane, and on base angle, arcuate cradle 1 two ends, planar screw 7 fixes the bar shaped of certain length From glutinous binder 8, thus constitute a kind of knee joint stably measured instrument.

Its longitudinal extent of scale 4 on described expansion link 3 is 30mm, and the intermediate value scale of scale 4 is parallel to outer spiral shell The top of stricture of vagina sleeve pipe 5, scale 4 spacing value is 1mm.
