Abstract

The present invention relates to an endoscope measuring ruler which is composed of a ruler handle and a ruler body. The present invention has the technical scheme that the upper end of the ruler handle is arranged on a fixed finger ring; the lower end of the ruler handle is connected with the ruler body; the front face of the ruler handle is provided with a bar-shaped through groove and a scale disc; both sides of the ruler handle are respectively provided with a bar-shaped through groove; the bar-shaped through grooves at both sides of the ruler handle are respectively provided with a sliding finger ring; the two sliding finger rings are respectively connected with an elastic steel wire ruler; the two elastic steel wire rulers extend out of two oblique holes at the end parts of the ruler body through inner diameters of the ruler body. The present invention can measure sizes of focal parts of various shapes with exact measurement and small error. Curative effects can be observed by the variation of the sizes of the focus parts before and after treatment, and the prognosis can be estimated.

Description

Endoscope measuring rule

The invention 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 invention is to provide a kind of endoscope measuring rule, 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 object of the present invention is achieved like this: 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, having the bar shaped groove and be provided with on chi handle front is with graduated ruler respectively to 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 the size of graduated ruler of reading tape this moment is by triangulation calculation or look into the size that computer chart just can be known the spot size of surveying accurately.

Advantage of the present invention is: 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 invention will be further described below with reference to accompanying drawing.

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

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

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:

L = \sqrt{{(L_{1} + \frac{φ}{\sqrt{2}})}^{2} + {(L_{2} + \frac{φ}{\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, 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, having the bar shaped groove and be provided with on chi handle front is with graduated ruler respectively to 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.
