Abstract

The utility model discloses a focus measurer under an endoscope. The focus measurer comprises a flexible outer sleeve, measurement inner cores arranged in the outer sleeve, and a handle arranged at the first end of the outer sleeve, wherein two through holes are formed in the tail end of the outer sleeve, an angle being less than 180 DEG is formed between the two through holes, the measurement inner cores extend out of the through holes, the other ends of the measurement inner cores are fixed on a vernier sleeved on the handle, the vernier is capable of sliding on the handle, and distance scales are arranged on the handle. The focus measurer has the beneficial effects that the focus measurer is matched with the endoscope for use, the tail end of the outer sleeve extends to the focus along with the endoscope, the position of the focus is determined by the endoscope, then the measurement inner cores extend out of the outer sleeve through in vitro operation of the vernier so that the size of the focus is measured, and the size of the focus is directly read from the distance scale on the handle, thus the operation is extremely convenient; the focus measurer is simple in structure, low in production cost and suitable for popularization.

Description

Focus measuring device under scope

Technical field

This utility model relates to medical apparatus and instruments, relates in particular to focus measuring device under a kind of scope.

Background technology

At present, in medical apparatus and instruments by endoscopic views patient focus, lack a kind of measuring device that can Measurement accuracy focus size, doctor can only be by the image range estimation size of tumor shown in scope, this just to clinical treatment stayed erroneous judgement may, for example gastric ulcer is greater than 2cm and will considers canceration, polyp is greater than 2cm will consider surgical operation therapy etc., once little saying is large, can bring huge mental burden and financial burden to patient.In addition, can not accurately judge that size of tumor also just cannot evaluate therapeutic effect, for example, evaluate the therapeutic effect of gastric ulcer, ulcer treatment has got well how many, is 30%, 60% or 90%, and accurate measurement just cannot do not judged; Polyp treatment diminishes polyp, concrete little how much also cannot judge, if just broadly range estimation just cannot compare, the evaluation of the treatment measures such as medicine is lacked scientific, can delay patient's treatment process, be there is to great threat in patient's health.

Application number is that 201220410951 patent discloses a kind of body lumen measuring device using in scope, but it exists following problem: one, product structure is complicated, makes trouble, and cost is high, and it is more difficult to promote; Two, under mirror, be difficult to control survey direction, cannot guarantee that outlet is towards the length of lesion or wide; Thereby three, be subject to the extruding of focus or mucosal surface and change angle and cannot guarantee 90 degree angulations, unwarrantable words are accurate size up just; Four, cannot measure the focus at knuckle place; Five, under mirror, reading is more difficult, run into common mucus or foreign body and disturb, or focus is far away, just cannot read at all; Six, 4 holes are different in size, also will try one by one enough length, troublesome poeration.

Utility model content

The technical problem that this utility model mainly solves is to provide focus measuring device under a kind of scope simple in structure, size that can Measurement accuracy focus.

For solving the problems of the technologies described above, the technical scheme that this utility model adopts is: focus measuring device under a kind of scope is provided, comprises the trocar sheath of a flexibility, the hands handle that is loaded on the measurement inner core in this trocar sheath and is arranged on trocar sheath head end; The tail end of described trocar sheath is provided with two through hole, between two through hole, have the angle that is less than 180 degree, described measurement inner core can stretch out from this through hole, and the other end of measuring inner core is fixed on the vernier being socketed on handle, described vernier can slide on handle, and described handle is provided with distance scale.

Wherein, the angle between described through hole is 60 degree.

Wherein, to stretch out the inner core end bending of described through hole be round end shape to described measurement inner core.

The beneficial effects of the utility model are: be used in conjunction with scope, trocar sheath tail end is extended to affected area with scope, by scope, determine lesions position, then by vernier, operate in vitro measurement inner core is stretched out to trocar sheath to measure focus size, and direct size of reading focus from the distance scale of handle, it is very convenient to operate, and the structure of itself is very simple, production cost is low, is suitable for promoting.

Main element symbol description: 10, trocar sheath; 11, trocar sheath head end; 12, trocar sheath tail end; 13, through hole; 20, measure inner core; 21, inner core end; 30, hands handle; 31, vernier; 32, distance scale; 40, scope; 50, digestive tract; 60, focus.

The specific embodiment

By describing technology contents of the present utility model, structural feature in detail, being realized object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.

Refer to Fig. 1, present embodiment is focus measuring device under a kind of scope, comprise a flexibility trocar sheath 10, be loaded on the measurement inner core 20 in this trocar sheath 10 and be arranged on the handle 30 on trocar sheath head end 11.

See also Fig. 1 and Fig. 2, described trocar sheath tail end 12 is provided with two through hole 13, between two through hole 13, there is the angle of 60 degree, described measurement inner core 20 can stretch out from this through hole 13, the other end of measuring inner core 20 is fixed on the vernier 31 being socketed on handle 30, described vernier 31 can slide on handle 30, and described handle 30 is provided with distance scale 32.

Refer to Fig. 3, measuring inner core end 21 bendings that inner core 20 stretches out the part of through hole 13 is round end shape, can prevent from like this cannot stretching out because misoperation causes measuring in inner core 20 retraction trocar sheaths 10 again.

Refer to Fig. 4, in practical operation, present embodiment and scope 40 are used in conjunction with, trocar sheath tail end 12 is extended to focus 60 places on digestive tract 50 with scope 40, by scope 40, determine focus 60 positions, then the duct that the operation by handle 30 is shifted out scope 40 by trocar sheath 10 a bit, vernier 31 operates in vitro and from through hole 13, stretches out the edge that trocar sheath tail end 12 makes two inner core ends 21 prop up focus 60 and can measure the size of focus 60 measuring inner core 20, and directly from the distance scale 32 of handle 30, reads the size of focus 60.Owing to measuring inner core 20 for thering is the bifurcated form of certain angle, can not shelter from the visual field of scope 40, and only need confirm whether inner core end 21 props up edge, can not cause cannot measuring and reading because mucus, food debris or feces etc. cling measurement inner core 20.In addition, if desired rotation direction is measured major diameter or the wide footpath of focus 60, can rotate by the shank of rotary handle 30 or rotation scope 40 direction of inner core end 21.

With respect to the prior art of mentioning in background technology, survey measurements of the present utility model carries out in vitro, comparatively directly perceived, also can complete operation when substantially unclear in the visual field, and operation is very convenient easily grasps, and the structure of itself is very simple.In addition, this utility model also has to be made simply, and cost is low, is applicable to promoting, and under direct-view, measures advantage accurately.

The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes this utility model description and accompanying drawing content to do; or be directly or indirectly used in other correlative technology fields, be all in like manner included in this utility model scope of patent protection.
