Abstract

PURPOSE:To accurately and easily measure the fine structure of an intracorporeal mucous membrane, by constituting the biopsy measure grasped by a biopsy forceps at the leading end thereof in a detachable manner by laminating two lusterless translucent ultrathin materials and providing a scale to the laminated part of both of them. CONSTITUTION:A biopsy measure is constituted by preliminarily applying a scale 62 to the surface of one ultrathin material 61a by printing and laminating the other ultrathin material 61b to the printed surface thereof. The dimension of the biopsy measure is below 1mm in a width and below 20mm in a length and graduations are provided at a 0.2mm-interval within a range of about 10mm. In actually measuring the lesion part generated in an intracorporeal mucous membrane, the grip part 63 of the biopsy measure 6 is grasped by a biopsy forceps 7 at the leading end thereof and inserted in an endoscope 1 from the forceps port 51 thereof to be allowed to reach the intracorporeal mucous membrane 8 from the forceps outlet 21 to be adhered to the lesion part 81. By observing this state under the illumination from an optical fiber, the dimension of the lesion part 81 can be accurately read.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention is a precision instrument used to measure the fine structure of the surface of the mucous membrane in the body in detailed examinations, treatments, etc. using a medical endoscope. This is related to an inspection measure (hereinafter referred to as a detailed inspection measure).

(Prior Art) Endoscopes are widely used for diagnosis and treatment of lesions in the duodenum, rectum, large intestine, esophagus, ear, nose, bladder, and the like.

In general, an endoscope 1 has a distal end section 2, which has a built-in I2 optical system, etc., and a bent section that can be moved vertically and horizontally by the operator's operation, as shown in Fig. 3. 3, a guiding section 4 and an operating section 5.

The operation section 5 is equipped with an operation knob for operating the bending section 3, various other operation buttons (not shown), a power supply section, etc., and a forceps port 51 for introducing the rough inspection forceps. It's branching out.

By the way, in the diagnosis or treatment of lesions using the endoscope described above, it is necessary to
It may be necessary to measure the dimensions of the

Conventionally, the measurement of lesions occurring on the surface of internal mucous membranes involves grasping a string-like object such as silk thread or rubber with the tip of M forceps, which is inserted through the forceps port of an endoscope, and inserting this into the lesion inside the body. However, this was done by measuring the dimensions of the lesion using marks attached to this string-like object.

(Problems to be Solved by the Invention) However, when measuring the fine structure of the intracorporeal mucosal surface such as a lesion using the above-mentioned conventional string-like object, the fine structure cannot be measured because marks can only be placed on the string-like object at intervals of about 5 nua. There was a problem in that not only could it not be possible to measure accurately, but also that the measurement accuracy decreased due to the thickness of the string-like material.

The present invention was achieved as a result of studies aimed at solving the problems of the conventional measuring tape for internal measurement described above.

Accordingly, an object of the present invention is to provide an excellent measuring tape for detailed endoscopic examination that can easily and accurately measure the fine structure (for example, a lesion) of the mucous membrane in the body.

[Structure 1 of the Invention (Means for Solving the Problems) In other words, the present invention provides a measuring tape for detailed examination which is detachably held at the tip of the fine examination forceps of an endoscope, and which is non-glossy and semi-finished. Made by laminating at least two sheets of transparent ultra-thin material,
It is characterized by having a scale on the pasted part.

(Function of the invention) The measuring tape of the present invention has an extremely thin structure because it has at least two sheets of glossy, translucent ultra-thin material laminated together, and a scale is provided on the laminated portion. A fine scale can be added, which can be grasped with fine inspection forceps,
By inserting it through the forceps port of an endoscope and reaching the microstructure of the mucous membrane such as a lesion that requires measurement inside the body, the target microstructure can be accurately and easily measured.

In addition, the measuring tape of the present invention has no distinction between the front and back sides, has good adhesion to the object, and has little measurement error due to thickness, and can also see through lesions at the same time as measuring them. Since there is no halation, the scale can be read accurately.

(Description of Embodiments) Hereinafter, embodiments of the measuring tape for maku-ken of the present invention will be described in detail with reference to the drawings.

FIG. 1(a) is a front view of the measuring tape for careful inspection of the present invention.
FIG. 2B is a side view of the same, and FIG. 2 is an explanatory diagram showing a measurement implementation situation using the measuring tape of the present invention.

As shown in FIG. 1, the measuring tape 6 for careful inspection of the present invention is
In this embodiment, two ultra-thin materials 61a and 61b are pasted together, a scale 62 is provided on the pasted part, and a gripping part 63 consisting of a protrusion or hole used for gripping with fine inspection forceps is provided at one end. It is constituted by providing.

Here, the ultra-thin material 61 is made of a matte and translucent material, such as cellophane, polyamide, polyester, polyethylene, polypropylene, Teflon, silicone, polyester, etc., and has a thickness of 20 to 200 microns. Preferably, the

The measuring tape of the present invention can be obtained by providing a scale 62 by printing or the like on the surface of one ultra-thin material 61a, and pasting the other ultra-thin material 61b to the printed surface.

In addition, the dimensions of the measuring tape 1 for careful inspection of the present invention are preferably less than 11 in width, less than 205 m in length, and less than 15 IllIl1 in width, and preferably have scales at intervals of 0.2III in a range of about 10 mm.

The measuring tape of the present invention is extremely thin and flexible, so it has good adhesion to lesions that occur on the surface of the mucous membranes in the body.Moreover, since it is translucent, it can be used to see through lesions and detect lesions. Dimensions can be accurately measured with high precision.

Next, in order to actually measure a lesion that has occurred in the mucous membrane of the body using the measuring tape of the present invention, as shown in FIG. 7 and insert it through the forceps port 51 of the endoscope 1 to reach the internal mucus 118 through the forceps outlet 21 and adhere to the lesion 81.

By observing this state using illumination from an optical fiber, the dimensions of the lesion 81 can be easily and accurately read.

In addition, since it is removable, when the target lesion 81 moves rapidly, it is also possible to place the measuring tape 6 on the lesion 81 for measurement.

After the measurement is completed, the precision measurement measure 6 may be retrieved from the body by handling the precision measurement forceps 7 from the forceps opening 51. Depending on the situation, the precision measurement measure 17-6 may be used for internal inspection as it is.
The endoscope 1 can also be left in the body and pulled out together with the endoscope 1.

[Effects of the Invention J] As explained in detail in the examples above, the measuring tape of the present invention has at least two sheets of non-glossy and semi-transparent wA thin material laminated together, and a scale is provided on the laminated portion. The structure is extremely thin and can be provided with fine scales, making it possible to accurately and easily measure microstructures such as lesions that require measurement inside the body.

In addition, the measuring tape of the present invention has no distinction between the front and back sides, has good adhesion to the object, and has little measurement error due to thickness, and can also see through lesions at the same time as measuring them. Since there is no halation, the scale can be read accurately.
