Abstract
The invention discloses a ligament rupture knee joint dislocation measuring device which comprises a dial indicator, a fixing block, a screw, a bracket and a bandage for binding the entire measuring device on the crus of a patient; the fixing block is firmly connected with the bracket; the screw passes through an internal threaded hole of a lug below the abdomen of the dial indicator and round holes at the two ends of the fixing block; the dial indicator is mounted above the bracket; a nut for axial positioning is mounted on the end part of the screw; a measuring head capable of keeping contact with the patient knee under the effect of a spring in the dial indicator is fixedly mounted at the front end of the dial indicator; and the bondage is fixed on the bracket. The entire device is bound on the crus of the patient by the bondage through the bracket, the measuring head of the dial indicator directly contacts with the patient knee, and when the doctor moves the crus of the patient back and forth, the knee joint dislocation caused by ligament hurt can be displayed on the dial indicator. The measuring device has a simple structure and low cost, and is convenient to use, quick, accurate and easy to popularize.
Description
Technical field
The present invention relates to measuring technique and field of medical, in particular to a kind of measuring device of contact ligament rapture knee joint dislocation.
Background technology
Knee ligament fracture or damage are a kind of more common sufferers, are more common in teenager, and the male is more than the women, and is especially common in the athlete, often in training or match, cause because of violent motion.Sometimes can hear the sound of ligament rapture when injured, just can not continue motion very soon again, or swelling, tenderness and hydrops appear in the knee joint place because of having an intense pain; The knee muscular spasm, the stiff knee of patient, knee joint is in compulsive position; Or stretch, or flexing, the breaks of knee joint side para-ligament has tangible pressure pain point; Sometimes also can touch the ligament broken ends of fractured bone of rolling up, be one of big disease of harm.
Present detection diagnostic means comprises that side stress test, drawer test, pivot shift test, patient are from master trip and the graceful test of clarke.These detection meanss not only fall behind but also are dangerous, easily the ligament that has damaged are caused the secondary injury.And pure mechanical yardstick detection is very original, and precision is low, measures inaccurate.Though it is relatively good that advanced CT detects effect, equipment is very expensive, and testing cost is high, and is not to develop for ligamentous injury of knee joint detects specially, and specific aim is not strong.
Therefore, develop a kind of easy to use, measure and to be specifically designed to diagnostic instrumentation---the ligamentous injury of knee joint checkout gear that detects ligamentous injury of knee joint accurately, be the task of top priority.
From the initial stage in age 90 o'clock 20th century so far; Surgical operation diagnosis automatization has obtained develop rapidly, and medical automatization auxiliary diagnosis is alleviating working doctor intensity, alleviates the patient suffering, improves diagnosis efficiency, improves the diagnosis degree of accuracy, improving the patient and seek medical advice and huge performance space is arranged aspect environment or the like.Yet being specifically designed to both at home and abroad at present fast and accurately diagnoses the device of ligamentous injury of knee joint not appear in the newspapers as yet.
Summary of the invention
The objective of the invention is to for ligamentous injury of knee joint provides easy accurate ligament rapture knee joint dislocation measuring device, thereby improve the auxiliary medical equipment of ligament injury diagnosis.
For realizing the object of the invention, adopt following technical scheme:
A kind of ligament rapture dislocation measuring device comprises dial gauge, fixed block, screw rod, support and is used for entire measuring device is bundled in the binder on patient's the shank that fixed block and support are fastenedly connected; Screw rod passes the internal thread hole of lug below the dial gauge abdominal part and the circular hole at fixed block two ends, dial gauge is installed in the top of support; The nut as axial location is equipped with in the screw rod end; The front end of dial gauge is installed with can keep the gage outfit that contacts with patient's knee under the inner spring action of dial gauge; Rotary screw can drive dial gauge and on support, move to regulate the initial position when measuring along the screw axis direction; Said binder is fixed on the support.
In the above-mentioned ligament rapture dislocation measuring device, said gage outfit is discoid; Said fixed block is fastenedly connected with sunk screw and support; Said binder is screwed on support.
In the above-mentioned ligament rapture dislocation measuring device, said support comprises the vertical part and the bending part that is used to install dial gauge that is used to install binder.
Because ligament injury or fracture are serious more, the knee joint dislocation is also just big more, so we need measure kneed magnitude of misalignment.The present invention is a survey tool with business-like dial gauge, and its front end is fixed a gage outfit (discoid), and the spring that relies on dial gauge inside to be equipped with keeps gage outfit to contact with patient's knee.The knee joint dislocation can show on dial gauge when moving patient's shank before and after the doctor, thereby concludes the degree of ligament injury.
Compared with prior art, the present invention has following advantage: doctor front and back in diagnostic procedure promote patient's shank, can consequent dislocation be measured through apparatus of the present invention, and then diagnosing patients ligamentum patellae degree of injury.This device energy measurement has advantages such as simple in structure, easy to operate, that certainty of measurement is high, cost is low, be easy to popularize because of the maximum magnitude of misalignment of knee joint that ligament rapture causes.
Description of drawings
Fig. 1 is the appearance assumption diagram of measuring device in the embodiment;
Fig. 2 is the partial sectional view of facing of device shown in Figure 1;
Fig. 3 is the work sketch map of adorning shown in the embodiment.
The specific embodiment
In order to understand the present invention better, be described further below in conjunction with accompanying drawing, but enforcement of the present invention is not limited thereto.
As Fig. 1, shown in Figure 2 be the structure chart of ligament rapture knee joint dislocation measuring device in this embodiment, comprise support 1, gage outfit 2, dial gauge 3, fixed block 4, screw rod 5, nut 6, binder 7.Gage outfit 2 is through the fixedly front end of dial gauge 3 that is threaded.Said support comprises two parts up and down, and the bottom is divided into the vertical part that is used to install binder, and top is divided into the bending part that is used to install dial gauge.Four sunk screws of fixed block 4 usefulness and support 1 are fastenedly connected, and screw rod 5 passes the internal thread hole (with the screw rod coupling) of lug below dial gauge 3 abdominal paries and the circular hole at fixed block 4 two ends, dial gauge 3 are installed in the upper section of support 1.Nut 6 is equipped with in screw rod 5 ends, as axial location.Rotary screw 5 can drive dial gauge 3 and on support 1, move to regulate the initial position when measuring along screw rod 5 axis directions.Binder 7 is screwed on support 1, entire measuring device is bundled on patient's the shank.
When the doctor uses, whole device is bundled on the shank of patient's bending earlier with three binders 7 on the support 1, then with gage outfit 2 roof pressures on patient's knee, rotary screw 5 can guarantee the initial position that contacts.Doctor front and back in diagnostic procedure promote patient's shank, and dial gauge 3 can measure consequent dislocation come, and then diagnosing patients ligamentum patellae degree of injury.
