Problems solved by technology

[0008] In the surgical treatment of the digestive canal and body cavity using conventional medical ports, when energy devices such as high-frequency knife are used, the surgical field of view may become poor
In addition, in surgical procedures, for example, when a conventional medical port is inserted into the anus, it may be difficult to properly fix it to the anus.

[0086] In this reference example, as Image 6 As shown, the medical port 101 includes a sheath 12 that is harder than the cylindrical member described in the above-described 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 , a duct 106 for air intake, and a duct 107 for air supply. The port part 104 is formed with a device insertion hole (not shown) that communicates the inside of the sheath 12 with the outside. The sheath 12 of this reference example has such a hardness that it can be maintained in a cylindrical shape by itself in a normal use state. Further, the air supply duct 106 is opened on the surface of the panel 2A on the side of the sheath 12 , and the air intake duct 107 is fixed to the inner surface of the sheath 12 , and the open end of the sheath 12 (on the same side as the panel 2A is arranged) the end on the opposite side) is open.

[0087] The panel 2A is different in that there is no...

[0090] like 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 which penetrates the inside of the sheath 12 is provided. .

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

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

Abstract

This medical port comprises: a face plate (2) in which a through hole is formed; a circular anchor ring (9), an inner diameter measurement thereof in one aperture end is smaller than an outer diameter measurement of the face plate (2); a moving member (10) which is coupled to the anchor ring (9) and the face plate (2), and which moves the anchor ring (9) relative to the face place (2) to bring the anchor ring (9) toward the face plate (2). The anchor ring (9) further comprises a tapering outer circumference face, and the aperture end of the smaller outer diameter measurement of the outer circumference face is faced toward the face plate (2) side.

Description

technical field [0001] The present invention relates to a medical port. This application claims priority based on US Patent Provisional Application No. 61 / 579,118 filed in the United States on December 22, 2011, the contents of which are incorporated herein by reference. Background technique [0002] Conventionally, when performing surgical treatment in the digestive tract or body cavity, medical instruments such as an endoscope apparatus and a treatment instrument are sometimes inserted into the digestive canal or the body cavity to perform the treatment. In such surgical treatment, in order to ensure the observation of the treatment target site by using the medical instrument, the surgical field of view for treatment, or to efficiently guide a plurality of medical instruments to the treatment target site, use of the medical instruments for insertion of these medical instruments Auxiliary medical port. [0003] As the medical port, a medical port attached to a natural ope...
