Description

[Detailed description of the invention] [Industrial application field] The present invention is particularly applicable to an endoscope treatment method that utilizes a hanging tool provided in a locker-type storage case, etc., and stores the endoscope by hanging it there. Regarding ingredients.

[Conventional technology]

As is well known, forceps, which are an example of this type of treatment tool, are used to insert a flexible tube section with a forceps section attached to the tip so that it can be opened and closed through the forceps channel of an endoscope to remove tissue fragments within the body cavity. Although they are used for collecting and treating them, it is most rational to store them when they are not in use, usually by hanging them due to storage space or convenience of storage and removal. It has been said that there is.

By the way, this type of treatment instrument can also be used for endoscopes with an insertion section of about 2.5 m in length, such as a duodenoscope, so the length of the flexible tube section is inevitably long. I have no choice but to become. At this time, when considering the height of the person handling the instrument, there is a limit to the height of the hook or other hanging device from which the treatment instrument is hung, so the flexible tube of the treatment instrument must be larger than the height of the hanging device. The remaining parts were left lying on the floor, which was not only unhygienic, but in some cases could even be stepped on and damaged.

Therefore, the present applicant has developed a method as described in Japanese Patent Publication No. 62-19172, but when using this method, when storing forceps, which is a type of treatment tool, the length of the forceps is reduced by about half. The cup-shaped double-opening forceps section at the tip is opened and locked into the engagement hole of the operator.

[Problem that the invention attempts to solve]

However, in the conventional treatment instrument,
Since the collars formed at predetermined intervals on the operator are disk-shaped, when this treatment instrument is hung and stored in a locker-type storage case, the collars come into contact with the wall of the case, There is a problem that a large storage space is required and the storage space is wasted. Further, when such a treatment instrument is placed on a desk or the like, if the flange of the operator is formed into a disk shape, there is a drawback that it is easy to roll and easily fall off the desk or the like.

The present invention was developed in view of these circumstances, and aims to propose an endoscopic treatment instrument that does not take up storage space in a storage case and can be prevented from rolling over from a desk, etc. The purpose is

[Means for solving problems]

The present invention is a hand-operated operating unit equipped with an operating element that is slidable along the axial direction of a shaft-like operating body that has a hanging part for a hanging tool provided in a locker-type storage case, etc. a flexible section whose base end is connected to the distal end of the shaft-like operating body; and an operating element provided at the distal end of the flexible section and along the axial direction of the shaft-like operating body. A treatment part that is operated by reciprocating sliding via an operating wire, and a pair of flanges formed on the operator, and an engagement hole through which the treatment part is formed in at least one of the flanges. The endoscopic treatment instrument is characterized in that at least one side of the flange of the operator is cut out and formed into a flat shape.

[Effect]

In the endoscopic treatment instrument of the present invention, the disc-shaped collar formed on the operator is cut out on one side and formed flat, so it does not roll off from a desk, etc. It can be prevented. In addition, even when storing the instrument by hanging it in a locker-type storage case, the flange of the operator is cut out and formed into a flat shape, so the treatment instrument must be stored tightly. I can do it. In addition, the engagement holes for locking the distal end of the flexible tube of the treatment instrument are located in a pair of flanges formed at a predetermined interval on the operator so as to follow the curved shape of the flexible tube. Since the tubes are staggered, there is no tendency for the flexible tube to curl even when the endoscopic treatment instrument is suspended and stored in a locker-type storage case.

〔Example〕

Preferred embodiments of the endoscopic treatment instrument according to the present invention will be described in detail below with reference to the accompanying drawings.

The endoscopic treatment instrument according to the present invention will be explained with reference to FIGS. 1 and 2. First, the endoscopic treatment tool includes a hand operation section 10 that the operator uses during operation, and an insertion section 12 that is inserted into the forceps channel of the endoscope.
It consists of First, to explain the hand operation section 10, there is a shaft-shaped body 14 in the center of the hand operation section 10.
An operator 16 is slidably fitted into this shaft-like body 14. The operator 16 has a cylindrical central portion and flanges 18 and 20 at its upper and lower ends. There are screws 22 in the radial direction on the lower collar 20.
is drilled, and this screw 22 is screwed into a slider 24 that is slidably disposed within the shaft-like body 14, whereby the operator 16 and the slider 24 are integrally connected. The screw 22 is positioned and guided within a guide groove 23 formed in the shaft-like body 14. A rear end portion of an operating wire 26 is fixed to the slider 24, and a tip end portion of the wire 26 is connected to a forceps portion 34 as described later. A ring-shaped finger hook 28 is formed at the upper end of the shaft-like body 14 . During operation, the thumb is inserted into the finger hook 28, and in this state, the operator 16 is operated using the index finger and middle finger. When this operator 16 is operated, a forceps section 34 connected via a wire 26 opens and closes, as will be described later.

Next, the structure of the insertion section 12 will be explained. The outer circumference of the insertion section 12 is formed of a flexible tube 30, and the upper proximal end 32 of the flexible section 30 has a shaft-shaped body 14 of the operating section 10. It is fixed at the bottom end. The wire 26 is inserted into the flexible tube 30 up to its tip. A forceps portion 3 is provided at the tip of the flexible tube 30.
4 is formed. The tip of the wire 26 is fixed to a connecting block 36.
Links 40 and 42 are rotatably supported via pins 38. The other ends of the links 40, 42 are rotatably connected via pins 44, 46 to forceps pieces 48, 50 formed in a substantially dogleg shape. The forceps pieces 48 and 50 are pivotally supported by a pin 52 on the forceps main body at their overlapping portions. Therefore, when the operator 16 is moved up and down and the operating wire 26 is pushed or pulled in, the forceps pieces 48 and 50 rotate in opposite directions about the pin 52 to perform opening and closing operations.

Furthermore, the sides of the collars 18 and 20 that are 180 degrees opposite each other are notched to form flat portions 18A, 18A, and 20.
A, 20A are formed. Also, this tsuba 18,
20 is formed with engagement holes 18B and 20B for the forceps portion. These engagement holes 18B and 20B are connected to the flexible tube 3.
They are formed with their positions shifted from each other so as to follow the curved shape of 0.

According to the endoscopic treatment instrument according to the present invention configured as described above, in order to store it in the locker type storage case 50 shown in FIG. The forceps section 34 is inserted into the engagement holes 18B and 20B, and then the forceps section 34 is opened and engaged with the operator 16, and in this state, the finger hook section 28 is inserted into the storage case 50.
It is hung from the L-shaped hanging tool 52 inside. In this case, the flanges 18 and 20 are cut out on both sides and are formed flat, so that they are in close contact with the wall 50A inside the storage case 50, thereby saving storage space.

In addition, the engagement holes 18 formed in the flanges 18 and 20
B and 20B are formed with their positions shifted from each other, and are formed in the flexible tube position when the flexible tube 30 is bent and bent, so that the flexible tube 30 does not have a tendency to curl.

Further, since the engagement holes 18B and 20B are formed at different positions, a frictional force acts on the insertion portion 12, and the forceps can be locked without opening the forceps.

The engagement hole may be only the lower hole 20B. In this case, the tip of the insertion part 12 comes into contact with the outer peripheral edge of the flange part 18, thereby generating a frictional force between the insertion part 12 and the engagement hole 20B and locking the insertion part 12 and the engagement hole 20B.

In addition, the flat parts of the flanges 18 and 20 prevent the endoscopic treatment instrument from rolling when placed on a desk or the like.
The endoscopic treatment tool will not fall off the desk or the like if it is not needed.

In the embodiments described above, forceps were used as an example of the treatment tool, but the present invention can also be applied to treatment tools such as an electric scalpel used endoscopically, such as a high-frequency snare.

[Effect of idea]

As explained above, according to the endoscopic treatment instrument according to the present invention, at least one side of the flange is formed flat, so when the endoscopic treatment instrument is stored by hanging it in a storage type rocker case. In addition to being able to save storage space,
It prevents it from rolling and does not fall easily from the top of a desk, etc.
