Abstract

The utility model relates to a measuring rule for an endoscope, which is composed of a rule handle and a rule body. The utility model has the technical proposal that the upper end of the rule handle is provided with a fixed finger ring sleeve, and the lower end of the rule handle is connected with the rule body. Strip-shaped through slots are arranged on the obverse surface of the rule handle, and a graduated circle is arranged on the obverse surface of the rule handle; both sides of the rule handle are respectively provided with the strip-shaped through slot. The strip-shaped through slots at both sides of the rule handle are respectively provided with a sliding finger ring sleeve. The ends of the two sliding finger ring sleeves are respectively connected with an elastic steel wire ruler. The two elastic steel wire rules extend from two oblique holes at the end of the rule body through the internal diameter of the rule body. The utility model can measure the sizes of the focuses with various shapes, and has the advantages of accurate measurement and small error. Through the size changing before and after the treatment of the focus, a doctor can observe the curative effect and estimate the prognosis.

Description

Measuring ruler for endoscope

This utility model belongs to a kind of medical diagnosis utensil, particularly a kind of thin measurement chi that encloses of pathological changes size of measuring when being applicable to various splanchnoscopy.

At present, endoscope observes the pathological changes magnitude range down, lack a kind of reliably accurate objective indicator, generally all inner sight glass doctor eye estimate, because sight glass has amplification, operant level difference, and object lens in addition is difficult to control apart from the distance between the focus, adopt this kind method measure inaccurate, error is big.Someone adopts the urinary catheter conduit or with having scale circular elongated rubber bar, sends into gastral cavity from the endoscopic instrument hole or enteric cavity is directly measured focus, though convenient, limited by the position, can not fully measure, lack accuracy.The CN86209992 patent disclosure a kind of fibrescope dip stick, surveyors' staff is a quadrilateral connecting rod structure, and it is sent into gastral cavity from the endoscopic instrument hole, reaches the focus surface, promotes scale by connecting rod and opens, shape is directly used visualization in line.Because the unstability of quadrilateral structure, so two scales are difficult to shape in line, this is the accuracy of influence measurement just.And the limited length of scale, the not overall picture of the big pathological changes of energy measurement.

The purpose of this utility model provides a kind of endoscope measuring rule, and it can accurately measure various focus magnitude range, observes size variation before and after the lesions treatment, and for surgical operation provides the accurate position and the tumor size of pathological changes, to instruct the correct art formula of selecting.

The purpose of this utility model is achieved in that endoscope measuring rule, form by chi handle and blade, be provided with the fixing snare that refers in chi handle upper end, be connected with blade in chi handle lower end, on chi handle front, have the bar shaped groove and be provided with graduated disc, respectively have a bar shaped groove respectively in chi handle both sides, on its both sides bar shaped groove, respectively be provided with a slip respectively and refer to snare, two slips refer to that the snare end all respectively is connected with an elastic wire chi respectively, and two elastic wire chis stretch out at blade end two angling holes by the blade internal diameter.

Its operation principle: when concrete use, to carry on the slip fingerstall earlier to " 0 " scale, this moment, elastic wire chi top was just in blade, it is sent into the focus the place ahead that will measure from the endoscopic instrument hole, with the fixing snare that refers to of thumb control, control two slip fingerstall circles respectively with forefinger and middle finger, during measurement, mobile slip refers to snare, make the elasticity blade stretch out the blade lower end by angled angling hole, article two, steel wire chi top refers in the pathological changes both side edges, and read size on the graduated disc this moment, by triangulation calculation or look into the size that computer chart just can be known the spot size of surveying accurately.

The utility model has the advantages that: it so just make it be suitable for measuring the focus size of different shape, and measurement size is accurate owing to adopt two elasticity measurement chis and become certain included angle to measure lesions position, and error is little.

The utility model is described in further detail below with reference to accompanying drawing.

Fig. 1 is a kind of concrete structure sketch map of the present utility model.

Fig. 2 is a measurement size schematic diagram calculation of the present utility model.

With reference to Fig. 1, endoscope measuring rule, it is made up of chi handle 6 and blade 7, be provided with the fixing snare 3 that refers in chi handle 6 upper ends, be connected with blade 7 in chi handle 6 lower ends, on chi handle 6 fronts, have bar shaped groove 4 and be provided with graduated disc 2, respectively have a bar shaped groove respectively in chi handle both sides, on its both sides bar shaped groove, respectively be provided with a slip respectively and refer to snare 1 and 5, two slips refer to respectively to be connected with an elastic wire chi 10 and 8, two elastic wire chis 10 and 8 respectively in snare 1 and 5 ends, and 9 liang of angling holes stretch out in the blade end by blade 7 internal diameters.

With reference to Fig. 2, the angle between blade end 9 and two angling holes is 90 °, and when the blade diameter was φ, then the length accurate to be measured of focus was:

$\mathrm{L=}\sqrt{\mathrm{(<figure-callout\; id="1"\; label="L"\; filenames="932271510\_DRIMG1.png"\; state="\{\{state\}\}">L</figure-callout>}{}_1+\frac{\Phi }{\sqrt{2}}{)}^2{\mathrm{+(<figure-callout\; id="2"\; label="L"\; filenames="932271510\_DRIMG2.png"\; state="\{\{state\}\}">L</figure-callout>}}_2+\frac{\Phi }{\sqrt{2}}{)}^2}$

(wherein: L1 and L2 read from chi handle graduated disc respectively)

When dip stick was used for certain endoscope, the blade diameter phi was also constant, and for example: as φ=3mm, when L1=20mm, L2=30mm, can calculate L-value by above formula is 39.0mm.

The endoscope of different size can the adapted different size dip stick, can change angle and blade diameter phi between blade front end two angling holes according to different needs, can calculate different L-value tables respectively according to different triangle formulas, directly consult, reduce and calculate link and trouble so that measure.

Claims (1)

1, a kind of endoscope measuring rule, it is made up of chi handle and blade, it is characterized in that on the chi handle, being provided with the fixing snare that refers to, be connected with blade in chi handle lower end, on chi handle front, have the bar shaped groove and be provided with graduated disc, respectively have a bar shaped groove respectively in chi handle both sides, on its both sides bar shaped groove, respectively be provided with a slip respectively and refer to snare, two slips refer to that the snare end all respectively is connected with an elastic wire chi respectively, and two elastic wire chis stretch out at blade end two angling holes by the blade internal diameter.
