DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an endoscope system provided with an endoscope used in an endoscopy or an operation under an endoscope, and equipment for treatment.

[0002]

2. Description of the Related Art Conventionally, by inserting an elongated insertion portion into a body cavity, an organ or the like in the body cavity can be observed, and if necessary, a treatment device (also referred to as a treatment tool) inserted into a treatment channel. Medical endoscopes capable of performing various types of treatments using a medical device are widely used.

[0003] The treatment instrument has a treatment instrument channel of an endoscope whose diameter is small (about 3 mm) and long (2 m).
It has a slender structure so that it can be inserted into a lumen. For this reason, when inserting this slender treatment instrument into the treatment channel of the endoscope, there is a possibility that the treatment instrument may be broken or damaged. Had to pay close attention to it.

For example, Japanese Unexamined Patent Publication (Kokai) No. 64-80335 discloses that in order to prevent damage during insertion of the treatment instrument, a member having appropriate elasticity is used for treatment equipment or the tip shape is made smooth. This shows an endoscope that improves the insertability.

[0005] Further, when performing a treatment endoscopically, since the endoscope and the treatment tool are independent, a medical technician can use both hands to operate a complicated endoscope and operate the treatment tool. And
Since several persons, including an attendant, must operate the endoscope and the treatment tool, skilled operation techniques are required. For this reason, in order to facilitate the operation between the endoscope and the treatment device, there is a device in which the operation unit of the treatment device is connected and fixed to the endoscope operation unit.

[0006]

However, as disclosed in JP-A-64-80335, improving the material and making the shape curved does not solve the fundamental problem. When a material is used, there are problems in that it is difficult to obtain the material, the manufacturing method is complicated, and it is not suitable for mass production, and the treatment tool becomes expensive.

In order to facilitate the operation between the endoscope and the treatment tool, in the case where the endoscope and the treatment tool are connected and fixed, the operation section of the endoscope interferes with the operation section of the treatment tool. Therefore, there was a problem that operability deteriorated.

Further, after the treatment, when performing post-treatment such as washing and disinfecting of the slender treatment equipment, there is a problem that it is difficult to wash, and it takes time for the post-treatment. When performing management, there is a problem that a storage space becomes large because the treatment tool is slender.

The present invention has been made in view of the above circumstances, and provides an endoscope system which prevents damage to a treatment tool, is easy to operate under an endoscope, and can be stored in a small space. It is aimed at.

[0010]

According to the endoscope system of the present invention, an endoscope module having at least one or more treatment means is attached to the distal end of the endoscope insertion portion via detachable means. It is possible.

According to this configuration, the endoscope module having the treatment means is attached to the distal end portion of the endoscope insertion section to perform an endoscopic treatment, and the endoscope module is connected to the endoscope insertion section. It can be stored in a state where it is removed from.
