イデイングチユーブに関するものである。[Detailed description of the invention] (Field of industrial application) This invention is a fiberscope, commonly known as a scope, which is used for observation, examination, diagnosis, and sometimes treatment of the inside of the large intestine. This invention relates to a sliding tube for guiding the insertion of a scope, which is used for various purposes.

があつた。(Prior art) An endoscope, that is, a scope, is passed from the rectum through the sigmoid colon, which is bent in a marked S-shape, to the descending colon.
Furthermore, the scope is inserted into the left colonic flexure and into the transverse colon, and the scope is moved back and forth and rotated while observing, testing, diagnosing, and sometimes treating the inside of the large intestine. Not to mention forward, backward, and rotation operations, as well as insertion into and withdrawal from a body cavity, were particularly difficult.

てきた。 Therefore, with the intention of alleviating this kind of difficulty, the scope is inserted from the rectum through the sigmoid colon, which has a marked degree of curvature, to the descending colon, and then straightened and fixed, allowing the scope to move forward and backward. Various sliding tubes for guiding scope insertion have been developed and proposed to facilitate rotational operation.

To create a straight line from the rectum through the sigmoid colon to the descending colon, attach this to the scope, place it on the hand control section, and first move the scope from the rectum through the sigmoid colon to the descending colon. This method aims to maintain a straight line from the rectum to the descending colon by inserting the insertion guide after achieving a certain degree of straightness. Many of the drawers had some problems.

のである。(Means for Solving the Problems) In view of the above-mentioned actual situation, the present invention was developed for the purpose of inserting a scope into a body cavity, withdrawing it from the body cavity, moving it back and forth within the body cavity, and rotating the scope. The bendable sliding tube body of the sliding tube for guiding the insertion of a scope is formed of an inner tube and an outer tube. The joint ring portions are arranged so as to be bendable in four directions, and the joint ring portions up to the other base cylinder side are arranged so as to be bendable in only one of the four directions. , is characterized in that it is designed to eliminate the various problems mentioned above.

ることができる。(Function) The sliding tube for guiding scope insertion according to the present invention has the above-mentioned configuration.
When inserting this into the descending colon from the rectum through the sigmoid colon, which has a marked S-shaped bend, the tip of the insertion section of the scope, such as a colonoscope, should be slightly wider than the tip of the sliding tube. If the tip is inserted while maintaining the protruding state and aligning the plane including the bending direction of the segmental rings, which are connected so as to be bendable in only one direction, with the plane including the bending surface of the sigmoid colon. The joint ring part of the sliding tube body near the section and the joint ring part up to the other base tube side are as follows:
Since it will bend according to the degree of curvature, such as the rectum, the S-shaped colon, which has a severe degree of curvature, and the descending colon, the sliding tube body can be moved to the desired location without any resistance. can be inserted.

ようになる。 Once the tip of the sliding tube has been inserted to the desired location within the body cavity, the base tube can be rotated 90 degrees in either direction, and the tip and the main body of the sliding tube can also be rotated 90 degrees. At this time, the segmental ring part of the sliding tube body near the tip, which can be bent in four directions, is bent according to the degree of curvature of the intestine in which it is placed. However, since the segmental ring part up to the other base tube side, which can be bent only in one direction, gradually straightens as it rotates, the sigmoid colon part, which is extremely bent, is also bent along with the large intestine part. Gradually, it becomes straight and maintains this state.

を極めて容易ならしめることとなる。 In other words, the distal end of the sliding tube body for forming the sliding tube for guiding scope insertion follows the shape of the intestine, and is straightened from the distal end, which can be bent in four directions, to the base tube side. This makes it extremely easy to move the scope forward and backward and rotate it.
そして、この挿入案内具の引出しは、上記と逆
の操作により極めて容易に行ない得る。 The insertion guide can be pulled out very easily by reversing the operation described above.

易に挿入することができる。 Since the sliding tube of the former embodiment of the present invention is constructed as described above, when it is inserted from the rectum into the descending colon via the sigmoid colon, which is bent into a marked S-shape, , the insertion part of a scope (not shown) is inserted into this, and its tip is slightly exposed, and the articulated rings 4 3 , 4 1 are connected to each other so as to be bendable only in one direction in the sliding tube body 1 . , 4 After aligning the plane including the bending direction of 1 with the plane including the bending plane of the rectum, sigmoid colon, and descending colon, insert the insertion part
When inserted together with the scope from the distal end 10 of the tube, the segment rings 4 4 , 4 2 . . . , 4 2 of the sliding tube body 1 near the distal end 10 and the segment rings 4 1 . , 4 1 , 4 3 are the rectal area and S
Since the tube body 1 can be bent freely depending on the degree of curvature, such as the sigmoid colon and the descending colon, which have a severe degree of curvature, the sliding tube body 1 can be easily moved to the desired location without any resistance. Can be easily inserted.

After inserting the tube to the desired location, by rotating the base tube Y by 90 degrees in one direction, the insertion portion X consisting of the distal end 10 and the sliding tube body 1 can also be rotated by 90 degrees. . At this time, the node rings 4 4 , 4 2 , which are bendable in four directions inside the sliding tube body 1 near the tip 10 ,
4 2 is bent according to the degree of curvature of the intestine in which it is placed, but the articulating ring 4 1 ..., 4 1 , 4 up to the other base tube Y can be bent only in one direction.
3 is gradually straightened as it rotates at this time, so the sigmoid colon, which is extremely bent, is gradually straightened together with the large intestine without any strain, and the sliding tube body 1 does not lose its shape. , this state will be maintained.

た。 That is, the distal end of the sliding tube body 1 itself for forming a sliding tube for guiding the insertion of a scope inserted into a body cavity conforms to the shape of the intestine in which it is placed, and is bendable in four directions. By straightening the intestines, which are extremely inconvenient when operating the scope, the intestines are straightened closer to the base of the tube, making it painful for the patient not only to move the scope forward and backward, but also to rotate it. It turned out to be extremely easy to do.

and the internal tube 3, the internal tube 3 is brought into close contact with the outer periphery of the flexible tube portion of the scope inserted into the body cavity through the sliding tube,
This will prevent leakage of gas introduced through the scope.

チユーブの提供を可能とするものである。(Effects of the invention) As is clear from the above explanation, according to the invention, when the invention is inserted into a body cavity, the insertion is made to the desired point while being bent according to the shape of the body cavity's curvature. The operation is extremely smooth, quick, and easy, reducing discomfort for the patient, and after insertion, it can be rotated by 90 degrees in either direction. Depending on the degree of rotation, the base tube side gradually straightens, and as this transition to straightening occurs, the bending of the body cavity itself gradually straightens very naturally, causing less pain to the patient. Moreover, it is a scope insertion guide that does not lose its shape, allows the insertion of the scope, and subsequent operations such as advancement/retraction and rotation without causing pain or discomfort to the patient. This makes it possible to provide a sliding tube.
