BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mainly used for the treatment and diagnosis of biliary tract diseases and kidney diseases by inserting a drainage tube into the affected area of the body to remove bile and urine, and by removing and inspecting gallstones. The present invention relates to a set for placing an indwelling tube for inserting an endoscope into the affected area for performing the operation.

2. Description of the Related Art Percutaneous treatment using a tube is performed for various diseases in the bile duct, gallbladder, renal pelvis, and ureter. That is, when a large-diameter tube or a tube having an outer diameter of about 5 mm necessary for inserting an endoscope is percutaneously inserted into a luminal organ such as a bile duct, gallbladder, or renal pelvis that requires treatment, This is a method in which fibrosis occurs as a foreign body reaction of the living body around the tube, and as a result, a fistula is formed, and the tube is taken in and out through this fistula.

By the way, in the conventional percutaneous treatment using a tube, the tube of narrow diameter is gradually replaced with the tube of large diameter at intervals of several days to one week, and it takes 5 weeks to replace the tube.
Although a fistula having a large diameter of about mm is formed, it takes a long time until the fistula is formed, and it causes a great deal of pain to the patient every time the replacement procedure is performed, which is a serious problem. As a method of shortening the period required for such surgical operation and treatment,
Japanese Utility Model Laid-Open No. 62-78938 discloses a small-diameter tube into which a guide wire can be inserted, a medium-diameter tube that covers the outer circumference of the small-diameter tube, and an outer diameter that covers the outer circumference of the small-diameter tube and is larger than the medium-diameter tube. Disclosed a biliary drainage expansion set consisting of a large, large diameter tube.

However, in order to insert an endoscope for the purpose of diagnosis, lithotripsy, excision of polyps, recovery of excised tissue, etc., the fistula between the chest wall and the liver or between the retroperitoneum and the kidney should be solid. It is necessary to settle. Therefore, it is necessary to indwell a large-diameter drainage tube for 2 to 3 weeks to wait for the formation of a fistula, and there is a problem that a long period of time is required when performing diagnosis or treatment with an endoscope. Further, as a method of shortening the period required for diagnosis and treatment by an endoscope, JP-A-3-195533 and JP-A-3-22296.
Japanese Patent No. 5 discloses an endoscope which is formed so that a plurality of tubes of different sizes can be inserted stepwise, a guide wire or a puncture needle can be inserted into the smallest diameter tube, and the largest diameter tube has a tear line. An insertion hole forming set is disclosed.

However, not only is it necessary to perform expansion and replacement operations several times until the maximum outer diameter product is placed, but this is not only complicated, but in the normal replacement operation, the length of the thin tube is 2 times that of the tube to be replaced. Need double the length,
In a minimum diameter tube, the length becomes extremely useless. In addition, if all of them are to be inserted one after another for one-time insertion, they are not integrated and are individually displaced, which makes smooth insertion operation difficult. Furthermore, in these systems, it is necessary to prepare a tube to be finally placed separately, which is costly in addition to the unnecessary length. In addition, the maximum diameter tube can be placed in double with the purpose of preventing damage and deviation of the indwelling tube, but it is necessary to expand the fistula up to the outer diameter of the indwelling tube, which requires extra expansion. It was supposed to increase pain.

The integrated indwelling tube set is extrapolated along the guide wire introduced into the affected area by the Seldinger method or ultrasonic puncture method to reach the affected area. As a method not using a guide wire, a method of inserting the puncture needle into the dilator and inserting it temporarily,
Furthermore, it can be appropriately arranged depending on conditions such as inserting into a detention tube without using a dilator and having a large puncture site, or requiring a small diameter tube to be detained. Here, by separating the sheath connector (7) and the connecting tool, removing the indwelling tube, dilator, and guide wire, and leaving only the peel-away sheath, it becomes possible to insert the endoscope, and diagnose, crush stone, etc. Can be treated. After the diagnosis and treatment are completed, the indwelling tube is inserted again from the peel-away sheath, and the sheath is removed while tearing the indwelling tube to complete the indwelling of the indwelling tube. In addition, if the purpose is only to place the tube without diagnosing or treating with an endoscope, it is not always necessary to integrate the peel-away sheath beforehand, but the connection required when fixing the indwelling described later. It is important that the device is externally placed on the indwelling tube.

After the tube is placed, the tube is fixed on the body using a tube fixing tool as shown in FIG. From the side of the indwelling catheter, a catheter fixing tool with a cut (11) opened is fitted. Then, the connecting portion (1) at the rear end of the tube fixing portion (9)
The indwelling tube and the tube fixing tool are integrated by fittingly connecting the connecting tool to 0). The tube fixing device is fixed to the body surface by suture fixing using a thread hooking hole (12), tape, or the like. Further, the catheter connector (4) of the indwelling tube is appropriately connected to a line such as a container for storing drainage drainage.

As described above, since the indwelling tube set according to the present invention can insert the endoscope and indwell the tube with a single insertion operation, the pain of the patient can be minimized by a short-term treatment. Since each component is integrated and fixed, it has excellent insertion operability and prevents the tube from deviating due to respiratory movement after tube placement, and also uses the indwelling tube itself for route expansion. This is useful as a more economical set.
