[0086] In this reference example, if Figure 6 As shown, the medical port 101 includes a sheath 12 that is harder than the cylindrical member described in the above-mentioned embodiment, and a panel 2A formed at one end of the sheath 12 . The panel 2A includes a main body 103 , a port portion 104 , an air supply duct 106 , and an air intake duct 107 . A tool insertion hole (not shown) that communicates the inside of the sheath 12 with the outside is formed in the port portion 104 . The sheath 12 of this reference example has such a hardness that a single body maintains a cylindrical shape in a normal use state. And, the above-mentioned air supply pipeline 106 is opened on the surface of the sheath 12 side of the panel 2A, and the above-mentioned air suction pipeline 107 is fixed on the inner surface of the sheath 12 and is connected to the opening end of the sheath 12 (with the panel 2A disposed thereon). end on the opposite side) opening.

[0087] The panel 2A is different...

[0090] Such as Figure 7 As shown, in this reference example, the medical port 111 is different in that, in addition to the sheath 12 described in the above-mentioned first reference example, an inner sheath 12A penetrating through the inside of the sheath 12 is also provided. .

[0091] A gap is opened between the sheath 12 and the inner sheath 12A. In addition, a gap between the sheath 12 and the inner sheath 12A functions as an air intake duct 117 . In addition, the gap between the sheath 12 and the inner sheath 12A may function as an air supply duct.

[0092] In this reference example, when the gap between the sheath 12 and the inner sheath 12A is used as the suction duct 117 , gas can be sucked from any position on the entire circumference of the sheath 12 . And, when the medical port 111 is inserted into the rectum, gas circulates in the rectum as follows: at the center of the rectum, gas is supplied to the back of the rectum; near the wall of the rectum, gas is suppl...

Abstract

The medical port includes: a panel (2), which is formed with a through hole; an annular fixing ring (9), the inner diameter of the opening end on one side of which is smaller than the outer diameter of the panel (2); and A moving member (10), which is connected to the fixed ring (9) and the panel (2), moves the fixed ring (9) relative to the panel (2) to draw the fixed ring closer to the panel (2) side (9); the above-mentioned fixing ring (9) has a tapered outer peripheral surface, and the opening end of the side of the outer peripheral surface with a smaller outer diameter faces the side of the above-mentioned panel (2).

Description

technical field [0001] The invention relates to a medical port. This application claims priority based on US Patent Provisional Application No. 61 / 579,118 filed in the US on December 22, 2011, and its content is cited here. Background technique [0002] Conventionally, when surgical treatment is performed in the digestive canal or body cavity, medical instruments such as endoscope devices and treatment instruments are sometimes inserted into the digestive canal or body cavity for treatment. In such surgical treatment, for the purpose of securing the surgical field of view for observation and treatment of the treatment target site using the medical instrument, or efficiently guiding a plurality of medical instruments to the treatment target site, a pair of inserting these medical instruments is used. Auxiliary medical port. [0003] As the medical port, a medical port attached to a natural opening such as an anus (for example, see Patent Document 1), a medical port attached...
