JP2006015102A - Movable sheath for inserting large intestine endoscope - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To facilitate insertion of a large intestine endoscope and to allow insertion of the large intestine endoscope into intestinum ileum and coelenteron. <P>SOLUTION: The subject large intestine endoscope sheath is formed by connecting a connecting shaft 8 formed of a music wire of high elasticity, transmitting its rotating power through an external gear 7, an internal shaft 3 and an internal gear 4 to an internal ring 2 mounted to a sheath cylinder 1 for the large intestine endoscope and partially projected outward, covering the internal ring 2 with a ring cover 5 made of soft rubber with high extensibility, and transmitting the rotating power to an outer ring 10 partially recessed inside, to rotate a connected spiral hard rubber 11, thus advancing to the inner part. A stopper is provided at the tip of a large intestine endoscope fiber to prevent the sheath from going further ahead from the tip of the large intestine endoscope fiber. The movable sheath can thereby advance the large intestine endoscope fiber itself together to the inner part. The inside is shut off from the outside by the ring cover 5, an elastic cover 6 and a connecting shaft cover 9. Internal contamination can thereby be prevented to keep hygiene. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

Detailed Description of the Invention

  The present invention makes it possible to move the sheath body through the large intestine endoscope fiber further back and back by concentrically rotating a spiral hard rubber connected with a ring attached to the outside of the sheath. In order to prevent the sheath from going forward from the tip of the colonoscopy fiber, the colonoscopy fiber itself can be advanced to the back by providing a ring-shaped stopper at the tip of the colonoscopy fiber. Can be inserted into the ileum and the ileum.

Conventionally, insertion of a colonoscope fiber takes time even for a skilled doctor, and it is not a little painful for the patient. The reason is that there are not a few parts that can not go deeper unless the colonoscope fiber is pushed or pulled from the outside with a certain amount of force, and the force applied from the outside is transmitted to the tip of the colonoscope fiber It is caused by misunderstandings. Further, it has been impossible to use the large intestine endoscope as it is as an endoscope for the small intestine.

The present plan was devised to solve these problems. If the drawings are described, the rotational power of the connecting shaft 8 made of a piano wire rich in elasticity is transmitted to the internal shaft 3 by the external gear 7, As the internal shaft 3 rotates, the internal gear 4 rotates, and the internal ring 2 that is partially convex outward rotates. The inner ring 2 is covered with a thin elastic rubber ring cover 5 that is rich in extensibility, and a part of the ring cover 5 is pushed outward by the convex portion of the inner ring 2 and is concentrically formed. A sheath tube 1 for a colonoscope is moved by rotating a ring-shaped hard rubber 11 which is connected to the outer ring 10 which is moved outward and the inner ring 10 is concaved by the movement. You can go to the back. In addition, the same movable sheath can be connected to the front and rear by the connection shaft 8, and the motion performance can be increased. The interior of the movable sheath of the present plan is blocked from the outside by the ring cover 5, the elastic cover 6, and the connecting shaft cover 9, so that internal contamination can be prevented and hygiene can be maintained.

Because of such a structure, the movable sheath of the present proposal enables insertion of the colonoscopy fiber up to the ileum and the ileum, and can be used after washing as in the case of the colonoscopy fiber.

Claims (1)

A flexible rubber cover with excellent extensibility that connects the connecting shaft and transmits the rotational power to a ring-shaped rotating body with a convex part on the outside attached to the front colonoscopy sheath. It is a large intestine endoscope sheath that enables you to rotate and advance the spiral hard rubber connected by transmitting rotational power to the outer ring that is covered and partly concave inside, A movable sheath that can move the colonoscopy fiber itself to the back by providing a stopper at the end of the colonoscopy fiber so that the sheath does not go forward from the tip of the colonoscopy fiber. is there.
