Abstract

The utility model relates to a fibrous endoscope measuring scale. The size of the gastral cavity (or the intestinal cavity) of the human body is measured by means of the endoscope. The fibrous endoscope measuring scale is characterized in that a new measuring ruler is adopted, the fibrous endoscope measuring scale comprises three parts: the operation, the guide and the measurement; the scale can be opened or closed by a thumb ring sleeve, and the measure of the focus can be completed. The utility model has the advantages of convenient operation, high precision, and direct viewing. The fibrous endoscope measuring scale is suitable for various cavity lenses to be provided with and be used.

Description

Fibrous endoscope measuring scale

This utility model belongs to the chamber of visual examination human body or the instrument of villous themeda, is specially adapted to the measurement of human body gastral cavity, enteric cavity inner disease foci.

Observe the internal lesions size at present following method arranged:

1, use endoscope's direct observation because sight glass has amplification, operant level difference in addition, object lens are difficult to control apart from the distance between the focus, adopt this kind method measure inaccurate, error is big.

2, use the scope scale, have and adopt the urine villous themeda to lead villous themeda or, send into gastral cavity (or enteric cavity) from the endoscopic instrument hole and directly measure focus with having the elongated rubber bar of scale garden shape, though convenient, limited by the position, can not fully measure the shortage accuracy.

The purpose of this utility model is for overcoming above shortcoming, provide a kind of novel dip stick, observes under endoscope and determines the pathological changes size, differentiates the good, pernicious of pathological changes, and lapsing to of tracing study ulcer pathological changes curative effect and precancerous lesion can be given accurate measurement.

This utility model is a dip stick, and operation part is made up of thumb snare, sliding sleeve, spring and body, and leader is made up of helical silk villous themeda and core bar, and measure portion is made up of scale, connecting rod and slide block.Make core bar in the in-draw of helical silk villous themeda by operation part, scale is opened or closure under the connecting rod effect, be placed on the focus after opening and measure the focus size.

Its operation principle, when dip stick is in closed condition, it is sent into gastral cavity from the endoscopic instrument hole, reaches the condition of illness surface,, make core bar protruding in helical silk villous themeda then with holding tight thumb circle and sliding sleeve, promoting scale by connecting rod opens, shape is directly used visualization in line, opens openhanded after the measurement, scale is drawn close state in line by pulling back of connecting rod, with after can take out from endoscope.

Description of drawings:

Fig. 2 is an endoscope measuring rule drive part schematic diagram

The accompanying drawings embodiment:

Dip stick provided by the utility model is by scale (1) (2), connecting rod (3) (4), slide block (5), core bar (6) are formed, operation part is made up of thumb snare (8), sliding sleeve (9), spring (10), body (11) and helical silk villous themeda (12), (as shown in Figure 1) be carved with scale on the scale, full chi is about 20mm, its middle finger snare is connected with slide block (5) by the core villous themeda, because functional unit work is easy to make scale to open or closure.

This utility model advantage: simple in structure, easy to use, measure accurately, directly perceived, be fit to be equipped with and use by various chambeies mirror.

Claims

1, a kind of fibrescope dip stick, it is made up of operation, guiding, measurement three parts, the slide block (5) that is characterised in that described measure portion by connection core bar (7) of the present utility model, one end is fixed on the slide block (5), in addition two ends be separately fixed at the pull bar (3), (4) at dip stick (1), (2) two ends and wherein an end be fixed on two dip sticks (1), (2) composition on the core bar (6).

2,, stretch out or closed dip stick (1), be carved with scale above (2) but it is characterized in that the left and right sides is straight by the described fibrescope dip stick of claim 1.
