Description
Technical field
Type of the present invention belongs to scientific experiment equipment, and it is solid to be related to a kind of noninvasive femur for rat knee joints angle measurement
Determine device.
Background technology
Range of motion (Range of motion, ROM) is also known as range of motion, reachable when referring to joint motion
The movement maximum radian arrived.The measurement of range of motion be evaluate muscle, bone, neural disease damage patient basic step, be
Evaluate one of the index of the range and degree of joint motions functional lesion.Main purpose is:Determine whether joint motion by
Limit, the reason of finding to influence joint motion；Determine the limited degree of joint motion;Determine that suitable therapeutic purpose, judgement may
The degree of rehabilitation；Objective basis is provided for selection therapeutic modality appropriate, method;The progress feelings of objective measurement range of motion
Condition, to evaluate the effect of rehabilitation, training；Power is provided for patient and treatment medical worker, objective materials are provided for scientific research
Deng.
In zoopery, we obtain the effect assessment number of drug or therapeutic scheme by measuring the passive ROM of rat
According to.Its principle is as follows：Postanesthetic rat femur is fixed on toggle, knee joint position leads in torsion sensor central point
Traction rat fibula is crossed, femur is made to generate certain angle displacement (generally expandable maximum angle with fibula）, turn round simultaneously
Power apparatus obtains the torque value under the displacement angle in real time, and the numerical value that can be studied between ROM and torque in this way is corresponding
Relationship evaluates the movable function in joint with this.Torque force device can also be made to reach a certain even twisting moment by traction fibula,
The ROM under this torque value is read and recorded in real time, is closed according to the numerical value change of ROM under different experiments stage same torque to evaluate
The development situation and development trend for saving movable function, to realize the objective evaluation to drug effect or rehabilitation scheme.
The research that research at present measures rat ROM is seldom, and difficult point is effective fixation of femur, and visible research is equal at present
Using invasive mode, i.e., the homemade triangle fixing device of implantation at rat femur, and when needing to measure, by this triangle device
It is connected and fixed with toggle, then implements to measure.Such mode advantage is good fixing effect, and data redundancy is good, but disadvantage
It is also obvious, under invasive environment, experimental animal easily infects, and raises and nurse that difficulty is big, and sample survival rate is low.
The present invention is mainly a kind of special fixture, to realize the noninvasive fixation of rat femur.Precision torsion meter is one
The common torque rating equipment of kind, there are many brand and model are available in the market.Present invention is generally directed to most normal in the market
The HP-10 type torsiometers seen are designed manufacture, can match application well.
Invention content
It is an object of the invention to solve the above problems, provide a kind of noninvasive for rat knee joints angle measurement
Femur fixing device.The present invention can be measured while realizing rat torque with angle in the case that noninvasive fixed, can be with
Realize preferable repeatability, compared to invasive mode, the survival rate of the sample both ensured also reduces the operation difficulty of experiment,
It is a kind of feasible gedanken experiment utensil.The present invention have it is simple in structure, easy to operate, experimental data is reproducible, ensure
The features such as survival rate of sample.
The object of the present invention is achieved like this：Including pedestal, horizontal moving frame, vertically move frame, lifting bolt, semicircle
Shape kerve, semicircle indent and angle scale；It is characterized in that：Pedestal is U-shaped structure, and base rear end is equipped with slide slot, in slide slot
Equipped with horizontal moving frame, horizontal moving frame upper end is connect by lifting bolt with frame is vertically moved, and vertically moves frame leading portion montant
Low side is equipped with semicircle indent, and lifting bolt upper end is equipped with knob, and pedestal is equipped with semicircle kerve, semicircle between two front ends
Shape kerve is connected centrally through the angle scale and connecting pin of rotary shaft and lower section.
Description of the drawings
The present invention will be further described with reference to the accompanying drawings.
Fig. 1 is front view of the present invention.
Fig. 2 is type left side view of the present invention.
Fig. 3 is vertical view of the present invention.
Specific implementation mode
As shown in Figure 1, Figure 2 and Figure 3, a kind of noninvasive femur fixing device for rat knee joints angle measurement, packet
It includes pedestal, horizontal moving frame, vertically move frame, lifting bolt, semicircle kerve, semicircle indent and angle scale.
Pedestal 1 is U-shaped structure, and 1 rear end of pedestal is equipped with slide slot 10, horizontal moving frame 2 is equipped in slide slot 10, and level is moved
2 upper end of moving frame is connect by lifting bolt 4 with frame 3 is vertically moved.
It vertically moves 3 leading portion montant low side of frame and is equipped with semicircle indent 6,4 upper end of lifting bolt is equipped with knob 5.
Semicircle kerve 7 is installed, semicircle kerve 7 is centrally through rotary shaft and lower section between 1 two front ends of pedestal
Angle scale 8 and connecting pin 9 connect.
Application method of the present invention is as follows：
1）Connecting pin 9 is inserted into HP-10 type torsiometer square holes, the fixing bolt on torsiometer is used in combination to lock, opens torsiometer,
It is set as the parameter needed.
2）By rat anesthesia, leg thigh to be measured end is placed at semicircle kerve 7, femur all in semicircle kerve 7,
Rat knee joints midpoint is overlapped with connecting pin midpoint.
3）Semicircle indent 6 is placed in suitable position above rat thigh by mobile and horizontal movable stand 2.
4）Turn knob 5, the pushing of lifting bolt 4 vertically move frame 3, semicircle indent 6 are pressed at rat thigh, and is given
Certain pressure is given, femur in thigh is made to be compacted.
5）Rat shank is stirred with finger, sees whether the rotation of knee joint angle is horizontal plane, if any deviation, can suitably be put
Loose semicircle indent 6 is locked again after finely tuning thigh angle.
6）After fixing, under natural conditions, removes the peel and reset on torsiometer, preparation starts to test.
7）Slowly traction rat shank stops and keeps, and read on angle scale 8 until torsiometer reaches predetermined value
Corresponding angle value is taken, and is recorded.
8）After being measured, turn knob 5, lifting bolt 4 rises, and rat huckle is taken out from fixture, in repetition
State the test that step starts next sample.
