Problems solved by technology

[0008] However, there is a problem that since the tube is made of a material having high flexibility so that the tube can be bent along a tortuous path in the body, the torque transmission performance is low. Twisting the base end of the tube also does not allow the front end of the tube to rotate about the length axis

Embodiment Construction

[0046] Hereinafter, a medical tube 1 according to an embodiment of the present invention will be described with reference to the drawings.

[0047] Such as figure 1 As shown, the medical tube 1 of the present embodiment has a tube body 2 made of a flexible material such as silicone resin, and a mouthpiece 3 attached to the proximal end of the tube body 2 .

[0048] The tube main body 2 has: a first lumen 4 penetrating in the longitudinal axis direction at approximately the center of the cross section of the tube main body 2; and a plurality of second lumens 5, 5a around the first lumen 4 They are arranged at intervals in the circumferential direction.

[0049] The first lumen 4 has a diameter into which the endoscope 6 can be inserted, and forms a channel for the endoscope. In the state where the second lumen 5a is not inserted with the treatment instrument 7, Figure 2A As shown, it is crushed, and when the treatment instrument 7 is inserted, it is Figure 2B As shown, it i...

Abstract

It not only maintains high flexibility, but also makes the treatment instrument protrude at a proper position relative to the endoscope. Provided is a medical tube, which has: a first lumen (4), which penetrates in the longitudinal axis direction of a tube body (2) made of a flexible material to form a channel for an endoscope; a plurality of second tubes cavities (5, 5a), which are spaced circumferentially around the first lumen (4) and pass through in the direction of the length axis of the tube main body (2) to form a channel for treatment instruments; the first mark ( 12) It is arranged on the inner surface near the front end of the first lumen (4), and determines the circumferential position of any second lumen (5, 5a) relative to the first lumen (4); And the second mark (13), which is arranged at the base end of the tube main body (2), displays the second lumen (5a) determined by the first mark (12).

Description

technical field [0001] The present invention relates to medical tubes and medical systems. Background technique [0002] Conventionally, a tube having a plurality of lumens into which an endoscope or a treatment instrument is inserted is known (for example, refer to Patent Document 1). [0003] The tube disclosed in Patent Document 1 has an expandable lumen in order to ensure a small tube diameter at the time of insertion and a large channel for insertion of a treatment instrument or the like. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese PCT Publication No. 2008-538709 Contents of the invention [0007] The problem to be solved by the invention [0008] However, there is a problem that since the tube is made of a material having high flexibility so that the tube can be bent along a tortuous path in the body, the torque transmission performance is low. Twisting the base end of the tube also does not allow the front end of...
