眼部だけを分離させた内視鏡が考案されている。[Prior Art] Recently, a television camera is attached to the eyepiece optical system of the endoscope so that the observation image guided to the eyepiece optical system of the endoscope can be viewed by a plurality of observers on a monitor television, or A method has been adopted in which an observation image guided to an eyepiece optical system of a mirror is recorded by a video system and repeatedly reproduced to improve the accuracy of diagnosis. By the way, the above method is also adopted in an endoscope used during treatment of an affected part such as an angioscope, but an endoscope used during treatment of the affected part is used by a user during treatment of the affected part. There is a distinction between a clean area that the user can touch and a dirty area that the user cannot touch. In this case, the TV camera is generally structured such that disinfection and sterilization cannot be performed. Therefore, the TV camera and the eyepiece of the endoscope to which the TV camera is connected should be touched by the user during the treatment of the affected area. It becomes a filth zone that can not be done. Therefore, as shown in JP-A-59-232311, an endoscope has been devised in which only the eyepiece is separated from the operating portion of the endoscope that the user frequently touches during treatment of the affected area. There is.

があった。[Problems to be Solved by the Invention] Generally, an endoscope having a thin insertion portion such as a blood vessel endoscope is not equipped with a bending mechanism. Therefore, the endoscope travels through the insertion portion of this type of endoscope. When inserting into a complicated lumen or changing the observation direction, it is necessary to rotate the insertion portion of the endoscope. However, in an endoscope in which the eyepiece is fixed by a TV camera, the TV camera is large and heavy, so that in the conventional configuration, it is difficult to rotate the insertion part of the endoscope, and the operability is poor. There's a problem. Furthermore, the connecting tube that connects the operation section of the endoscope body and the observation section has a structure that is difficult to twist to protect the built-in objects, so it is impossible to force the endoscope by applying a large force. When an attempt is made to rotate the insertion portion, a large force acts in the rotation direction on the optical fiber bundle, the treatment instrument insertion channel, the insertion portion, and the like arranged in the endoscope body. Therefore, the optical fiber bundle may be broken, the treatment instrument insertion channel or the insertion portion may be buckled, and the endoscope may be seriously damaged.

性が悪くなる問題があった。Further, Japanese Utility Model Laid-Open No. 56-26721 discloses a flexible tube in which an engaging portion is formed at a tip edge of a fixed tube portion provided in an operation main body portion of an endoscope and a tip is connected to a hard tip portion. The other end that connects the rear end portion to the hollow connecting member, rotatably fits the hollow connecting member into the fixed pipe portion, and further engages the hollow connecting member with the engaging portion of the fixed pipe portion. A hollow connecting member rotating member having a hollow portion is slidably fitted onto the hollow connecting member rotating member in an unrotatable state, and the engaging portion of the hollow connecting member rotating member and the engaging portion of the fixed pipe portion are engaged with each other. There is shown a configuration in which the flexible tube can be rotated together with the hollow connecting member while the fixed tube portion remains stationary by releasing the engagement. However, in this case, normally, the structure is such that the engagement between the hollow connecting member rotating member and the engagement portion of the fixed tube is held in the engaged state by the spring force of the spring, When rotating the flexible tube, first, the hollow connecting member rotating member is slid in the axial direction against the spring force of the spring to engage the engaging portion of the hollow connecting member rotating member with the fixed pipe portion. There is a problem that operability deteriorates because a troublesome work for releasing the engagement with the part is required.

It is possible to rotate the insertion portion 6 up to an arbitrary angle without the rotation of the insertion portion 6 being hindered by the cord or the like attached to the eyepiece portion 7 when rotating the insertion portion 6. Furthermore, due to the flexibility of the connecting tube 4 that connects the insertion portion 6 side and the eyepiece portion 7, the insertion portion 6 side can be moved not only with respect to the eyepiece portion 7 but also horizontally and vertically. It was done like this.

る。Therefore, in the structure described above, the rotary connection mechanism section 5 is provided between the operation section 2 of the endoscope body 1 and the connection tube 4 on the observation section 3 side.
Since the rotary connection mechanism section 5 allows the operation section 2 of the endoscope body 1 and the connection tube 4 on the observation section 3 side to be freely rotated, it is possible to use the rotation connection mechanism section 5 like an angioscope. When the insertion portion 6 of the endoscope in which the bending mechanism is not attached is inserted into the complicated lumen of traveling or the observation direction is changed, the observation portion 3 side is held in a fixed state, The operation section 2 side of the mirror body 1 can be rotated together with the insertion section 6. Therefore, even if the endoscope has the eyepiece 7 fixed by the television camera, when the insertion portion 6 is rotated around the axis, the insertion portion 6 is attached by the light guide cord 8 or the like attached to the eyepiece 7. It is possible to rotate up to an arbitrary angle without the risk of being hindered from rotating. Furthermore, due to the flexibility of the connecting tube 4 that connects the insertion portion 6 side and the eyepiece portion 7, the insertion portion 6 side can be moved not only with respect to the eyepiece portion 7 but also horizontally and vertically. Therefore, the operability of the insertion portion 6 can be improved. Furthermore, since it is not necessary to force the endoscope 6 to rotate by force when the insertion portion 6 is rotated, unlike the conventional case, the optical fiber bundle disposed inside the endoscope body 1 is not required. Therefore, there is no fear that a large force acts in the rotational direction on the treatment instrument insertion channel, the insertion portion 6, or the like. Therefore, it is possible to eliminate the possibility that the optical fiber bundle is broken, the treatment tool insertion channel or the insertion portion is buckled, and it is possible to prevent damage to the endoscope and improve the durability. Also, the small diameter portion 18a of the fixing ring 18
The first stopper pin 20 projecting on the outer end surface of the and the second stopper pin 21 projecting on the outer peripheral surface of the coupling ring 15 are between the operation portion 2 side and the observing portion 3 side coupling pipe 4. Are arranged at positions rotated by 180 ° while being held at the neutral position of the rotation operation, and the neutral position is associated with the rotation operation between the operation unit 2 side and the connection pipe 4 on the observation unit 3 side. The first stopper pin 20 and the second stopper pin 21 in a state where they are both rotated clockwise and counterclockwise by 180 °.
And the rotation between them are regulated, so that it is possible to reliably prevent an excessive rotation between the operation section 2 side and the connection tube 4 on the observation section 3 side. it can.
