Description
Technical field
The present invention relates to a kind of length measurement method, measuring motion and measuring appliances, more particularly to one kind is for measuring body
The long method, apparatus of survey in vivo and its seal wire ruler of interior cavity physical length.
Background technology
Currently, measurement of length mainly uses the equipment such as gage, length measuring instrument, since these long methods of survey or instrument are
It is directly measured from the outside of measurand, however, urethra is located in the bodies such as human body, animal, due to bodies such as human body, animals
Blocking leads to not the length for the measurand surveyed using equipment such as existing gage, length measuring instruments, it is, therefore, desirable to provide
A kind of measurement method and measuring device can obtain human body, animal body using or by this measurement method and measuring device
The physical parameter of urethral length, the length of vessel of equal internal bodies etc..
Internal cavity includes urethra, blood vessel etc..Ankylurethria is one of Urology Surgery common disease, long section ankylurethria
Processing is one of Urology Surgery problem, and although ankylurethria measurement of length is not belonging to operative treatment, but need root due to preoperative
Determine operation plan according to the length of ankylurethria, less than 1cm it is narrow can otomy in row cystoscope ankylurethria, for super
Crossing the narrow of 1cm needs open surgery, length to be more than the ankylurethria of 3cm or even need that buccal mucosa or periglottis is taken to be transplanted to
On narrow section urethra bed, therefore, preoperative physical parameter i.e. its narrow length for being necessary to accurately measure ankylurethria.Face at present
The length for assessing ankylurethria on bed using the method for urethrography estimates ankylurethria segment length, nothing using X-ray examination
It is required to the x-ray radiation by larger dose by medical staff and patient, currently without dedicated for internal cavity physical length
Device, can only be tended to out without reference to object as scale by means of other instruments, the narrow segment length of "ball-park" estimate
Now estimate the situation to go wrong, for long section ankylurethria, even more can not accurately calculate ankylurethria length, or even influence hand
The formulation of art scheme needs to change operation plan in art, increases the wound to patient, reduces the success rate of operation, made to patient
At great pain.
Invention content
The present invention, which provides, a kind of can accurately, intuitively measure internal cavity narrow length and easy to operate for measuring
The long method, apparatus of survey in vivo and its seal wire ruler of internal cavity physical length.
The present invention uses following technical solution：
A kind of long method of survey in vivo for measuring urethra physical length of the present invention：Prepare a conduit, a seal wire ruler and
Contrast agent, the seal wire ruler include elastic filament bar, and salient point is equipped on elastic filament bar, and the density of salient point material therefor is more than
Contrast agent, and each spacing between adjacent salient point is equal, and conduit and seal wire ruler are then inserted to be measured section of internal cavity, then
Contrast agent is injected into cavity using conduit, after contrast agent is full of to be measured section of cavity, stops contrast agent injection, simultaneously by x-ray
Using density more than the to be measured section of cavity that the salient point and contrast agent of contrast agent are shown, directly read to be measured on seal wire ruler
The salient point sum measured between origin and destination for measuring section cavity, finally uses the salient point of the spacing and to be measured section of cavity between salient point total
Number obtains the physical length of to be measured section of cavity.
A kind of internal measuring motion for measuring internal cavity physical length of the present invention, including conduit and seal wire
Ruler, the conduit are used to inject contrast agent to urethra, and the seal wire ruler includes elastic filament bar, are equipped on elastic filament bar convex
The density of point, salient point material therefor is more than contrast agent, and each spacing between adjacent salient point is equal.
A kind of seal wire ruler used in the internal survey for measuring internal cavity physical length is long of the present invention, packet
Elastic filament bar is included, salient point is equipped on elastic filament bar, the density of salient point material therefor is more than contrast agent, and each to adjacent convex
Spacing between point is equal.
Compared with prior art, the invention has the advantages that：
（1）The present invention can accurately obtain length parameter with intuitive way, and it is long that the present invention can not only measure linear cavity
Degree, can accurately more measure the cavity bending length of bending.
The present invention is higher than the seal wire ruler of contrast agent using density, and seal wire ruler is being inserted to ankylurethria section and is injecting contrast agent
Afterwards, it is easily achieved the coincidence of the salient point and cavity start position to be measured of the head end of seal wire ruler under X-ray examination, avoids seeking repeatedly
Cavity starting point to be measured is looked for, the complete display image being inserted in seal wire ruler in ankylurethria section can be obtained by x-ray, thereby clearly
Clear complete image, internal linear measure longimetry is converted to macroscopic externally measured, and the outside for realizing internal length is intuitively surveyed
Amount, and it is made to be converted into the simple measurement method such as common ruler.
In complete display image, salient point clearly indicates in the picture, and can accurately and directly read and fall
The salient point sum of ankylurethria section to be measured, through simple computation, i.e. ankylurethria section to be measured can be obtained by being multiplied by spacing with salient point sum
Length, therefore, the present invention can obtain accurate internal length parameter.
The present invention can accurately measure the cavity bending length of bending.The seal wire ruler of the present invention is inserted into the chamber to be measured of bending
Behind road, as shown in figure 8, seal wire ruler bends therewith, and is presented the curved shape to match with the cavity to be measured of bending, to
So that the length shown on seal wire ruler is equal to the bending length that chamber is surveyed in bending, behind clearly to be measured section of origin and destination, so that it may with
Accurately measures bending line or be bent the length of curve of cavity containing bending line.
（2）Conduit is equipped with graduation mark and can directly be surveyed when seal wire ruler to be inserted to the starting point of to be measured section of internal cavity
The beginning or end of to be measured section of internal cavity is measured at a distance from cavity, such as：Ankylurethria length is measured when using the present invention
When, so that it may directly to measure the beginning or end of ankylurethria section the distance between to orificium urethrae externum.
（3）Contrast agent is injected by the conduit of the present apparatus, contrast agent enters cavity to be measured, such as：It is narrow for measuring urethra
When narrow section of length, the urethra of narrow section is entered by the trepanning of body portion front end, specifies narrow section proximally and distally, passes through meter
Number narrow section urethra proximally and distally between steel wire segment number to calculate the length of narrow section urethra.
