JP2003204921A - Transparent hood with cleaning function for endoscope - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a transparent hood capable of simultaneously executing a care/treatment action and a cleaning action by adding a lesion cleaning function to the transparent hood itself mounted at the tip of an endoscope, and enabling to execute this function without using a forceps hole of the endoscope. <P>SOLUTION: An oblique hole 5 is bored on a cap part 1 of the transparent hood, and the tip of a two meter long tube 3 is fitted and bonded to the hole. A connecter 4 capable of mounting the tip of a syringe is mounted on the opposite side. The oblique hole 5 of the cap part 1 sets an angle so as the tip of a water line (imaginary line 6) of the poured cleaning water and the tip of a care/treatment tool (imaginary line 7) to touch the lesion part. By mounting the hole 5 on the outer side of the endoscope, the inside of the cap part 1 can always be cleaned via the tube 3, and the forceps hole of the endoscope body is used exclusively for inserting the care/treatment tool, and thus, the care/ treatment action and the cleaning action can be simultaneously executed. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to add a cleaning function directly to a transparent hood attached to the distal end of a medical endoscope, and the added cleaning function does not use forceps holes of the endoscope. The present invention relates to a technique for facilitating treatment / treatment with an endoscope by enabling simultaneous treatment / treatment and washing by enabling washing.

2. Description of the Related Art When performing treatment / treatment under an endoscope,
There are cases where the patient's respiratory fluctuation is so strong that a certain distance from the target lesion site cannot be maintained, or no matter how the endoscope body is operated, the target lesion site cannot be viewed from the front. With a transparent hood that is attached to the tip of a conventional endoscope, the tip of the endoscope with this transparent hood is pressed near the lesion to maintain a constant distance from the lesion and to front the lesion. I was able to see it. In other words, the purpose was to ensure a good visual field of the lesion by keeping the distance from the tip of the endoscope.

[0003]

However, in the conventional transparent hood, no consideration has been given to securing a visual field by solving stains such as mucus or bleeding on the lesion. Usually, dirt such as mucus or bleeding in the lesion is solved by inserting a syringe filled with washing water into the forceps hole of the endoscope body and injecting the washing water, but there is only one forceps hole in the endoscope body. Therefore, only one of the cleaning action and the treatment / treatment action of the lesion that can be performed only by using the forceps hole can be performed. There are many mucus and bleeding lesions in the organs.First, the lesion is cleaned, and then the treatment / treatment device is inserted into the forceps hole of the endoscope to move to treatment / treatment. Is often encountered when the patient's vision cannot be maintained and treatment cannot be continued. In particular, in the case of hemostatic treatment for hemorrhagic lesions, in a conventional transparent hood, there is a case where the bleeding blood is stored in the cap portion and deteriorates the visual field. In such a case, cleaning and treatment of the lesion area have been performed until now.
In order to continue the treatment, the treatment / treatment device was repeatedly inserted and removed with the forceps hole of one endoscope, and cleaning and treatment / treatment were alternated. Therefore, in the present invention, a function of enabling the cleaning action is added to the transparent cap itself, which secures the visual field only by keeping the distance from the lesion, and the added cleaning function does not use the forceps hole of the endoscope. By making it possible to wash without doing this, it is an object to eliminate this withdrawal and insertion, and to be able to perform treatment / treatment and washing at the same time.

[0004]

Means for Solving the Problems A side hole is formed in a cap portion of a conventional transparent hood, and a washing tube is adhered thereto from the outside of the cap portion. The transparent hood with a cleaning function for an endoscope according to the present invention is conventionally put on the tip of the endoscope, and the tube is tape-fixed to the endoscope body. By attaching a connector to the opposite side of the tube and injecting washing water from there, it is possible to always wash through the tube in the transparent hood. By externally attaching this tube to the endoscope body, it can be washed without using the forceps hole of the endoscope, so the forceps hole of the endoscope body is dedicated to the treatment and treatment instruments.
You will be able to perform treatment and cleaning at the same time.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION A cap portion 1 of a conventional transparent hood.
Make a bevel 5 less than 2 mm in the area corresponding to
180 that is longer than the body of the endoscope
To 230 cm of tube 3 is glued. The oblique hole 3 formed in the cap portion 1 is the water line tip of the injected washing water (imaginary line 6), the tip of the treatment / treatment device (imaginary line 7) and the tip of the cap that are ejected from the forceps hole of the endoscope body. Set the angle so that they intersect. The tube 3 is fixed to the outside of the endoscope main body with a tape, so that the outer diameter of the tube 3 is set to less than 2 mm so as not to hinder the insertion of the endoscope into the subject. On the other hand, on the opposite side of the tube 3, a connector 4 to which the tip of a normal syringe can be attached is attached. In this completed hood, the endoscope mounting portion 2 is covered on the tip of the endoscope as usual, the tube 3 is tape-fixed to the main body at about 5 places, and the tip of the syringe filled with washing water is fitted into the connector portion 4. The device is ready and the actual treatment / treatment is performed. As a result, the inside of the cap portion 1 can always be cleaned through the tube 3, and the forceps hole of the endoscope main body can be treated and treated.
It is dedicated to medical treatment equipment and can perform treatment / treatment and cleaning at the same time.

[0006]

[Examples] When hemostasis of hemorrhagic lesions of the digestive tract is performed, the transparent hood with a cleaning function for an endoscope according to the present invention is attached as described above, and the endoscope is inserted into a subject. An instrument for hemostatic treatment, for example, a clip device is inserted into the forceps hole of the endoscope main body, the tip of the clip device is pulled out from the tip of the endoscope, and the clip is opened. Hold. When the opened clip is located right above the bleeding site (point) by operating the endoscope body, the distal end of the cap part 1 is pressed against the digestive tract wall. The bleeding site (point) is washed while injecting the washing water from the syringe filled with the washing water to secure the field of view and surely stop the bleeding by sandwiching the clip.

[0007]

EFFECT OF THE INVENTION The transparent hood with a cleaning function for an endoscope according to the present invention creates an environment for facilitating treatment / treatment by enabling treatment / treatment and washing at the same time.
In addition, the inspection time and treatment / treatment time can be shortened. In addition, hemorrhagic lesions also lead to a reduction in blood loss.
