Stem 100 serves as a skeleton of the laparoscopic surgery single port of the present invention, made of a hard material. In particular, the outer surface of the stem 100 is formed with a plurality of exhaust grooves 101 in the longitudinal direction. In addition, the outer surface of the stem 100 is formed with a collecting groove 102 in the circumferential direction so as to communicate with the plurality of exhaust grooves 101. Further, the stem 100 has a flat shape in its center, i.e., its upper and lower parts are lower than the center so that the lower part of the stem 100 is opened and the wide silicon lead 300 is positioned on the upper part of the stem 100. It has a shape with a wide diameter. In addition, the stem 100 has a cylindrical shape such that surgical instruments (not shown) are passed therein.

For example, the stem 100 described above may be configured to be divided into an upper stem 110 and a lower stem 120 to facilitate injection. The upper stem 110 forms an upper portion of the stem 100 and is made of a hard water material. The lower stem 120 forms a lower portion of the stem 100 and is made of a hard water quality material. At this time, the exhaust groove 101 is formed in succession on the outer surface of the lower stem 120 and the upper stem 110, and the collecting groove 102 is formed in the upper stem 110. In addition, since the incision 121 is connected to the exhaust groove 101 at the lower end of the lower stem 120, the gas flowing into the incision 121 is directly guided to the exhaust groove 101. The upper stem 110 and the lower stem 120 may be connected by the stem connecting unit 130. In detail, the stem connection part 130 includes an extension part 131 extending downward from the upper stem 110, a locking protrusion 132 protruding from the outer periphery of the extension part 131, and a lower stem 120. It includes a locking groove 133 is formed to penetrate through the inner circumference of the portion overlapping the extension portion 131 to correspond to the locking projection. In particular, as shown in FIG. 2, the upper stem 110 is rotated so as to be fastened to the lower stem 120, that is, when the upper stem 110 is rotated so that the locking protrusion 132 is properly guided and fastened. The groove 133 extends obliquely to the top of the lower stem.

In addition, the stem 100 described above surrounds the outer surface of the lower stem 120 and corresponds to the plurality of exhaust grooves 101 so that the plurality of exhaust grooves 101 described above are not blocked by the silicon cover 200 described later. It may further comprise a hard auxiliary member 140 formed with a plurality of auxiliary grooves 141 on the inner surface. In particular, as shown in FIG. 5, such that the auxiliary groove 141 of the auxiliary member 140 does not deviate from the exhaust groove 101, that is, the auxiliary member 140 does not rotate relative to the lower stem 120. The auxiliary member 140 may further include a location protrusion 142, and the lower stem 120 may have a location groove 125 corresponding to the location protrusion 142.

The silicon cover 200 surrounds the outer surface of the stem 100 made of the above-mentioned hard material, and is made of a soft silicone material to minimize the external injury of the body since it is a part directly contacting the body. In addition, the silicon cover 200 has a shape substantially similar to that of the stem 100 described above except for the lower portion thereof. The lower portion of the silicone cover 200 has a larger diameter and extends more than the lower portion of the stem 100 so that it does not fall out of the abdominal cavity 10 and is correctly seated. Of course, since the silicon cover 200 is made of a flexible silicone material, the silicon cover 200 may be smoothly inserted into the abdominal cavity 10 through the through hole 11. In particular, the inner surface of the silicon cover 200 is formed with a guide groove 201 in communication with the aforementioned collection groove 102.

For example, the silicon cover 200 described above may have a configuration divided into an upper cover 210 and a lower cover 220 to facilitate injection, such as the stem 100 described above. The upper cover 210 surrounds the upper stem 110 described above and is made of a flexible silicone material. The lower cover 220 surrounds the lower stem 120 and is made of a flexible silicone material. At this time, the guide groove 201 is formed on the inner surface of the upper cover 210. The upper cover 210 and the lower cover 220 may be connected by the cover connection unit 230. In detail, the cover connecting portion 230 has a structure in which the upper cover 210 and the lower cover 220 overlap each other, and the thickness thereof is set so that the thickness of the overlapping portion is not greater than the thickness of the other portion.

The silicon lead 300 covers the upper opening 202 of the silicon cover 200 and is fastened to the upper end of the upper cover 210 described above. In particular, a plurality of sleeves 500 are formed in the plane of the silicon lead 300. In addition, a discharge port 301 communicating with the guide groove 201 of the upper cover 210 is formed at one side of the plane of the silicon lead 300, and the gas discharge pipe 600 is connected thereto. In addition, a through hole 302 through which the gas injection pipe 400 to be described later passes is formed in the plane of the silicon lead 300. Furthermore, as the silicon lead 300 has a configuration separated from the silicon cover 200, when the sleeve 500 is required to be replaced, only the silicon lead 300 needs to be replaced, thereby significantly reducing the replacement cost.

The gas injection pipe 400 injects gas into the abdominal cavity 10 and is inserted into the through hole 302 of the silicon lead 300. In particular, the lower portion of the gas injection pipe 400 based on the silicon lead 300 is provided on the inner surface of the stem 100. As another example, although not shown, the length of the gas injection pipe 400 is positioned so that the lower end of the gas injection pipe 400 is located below the lower end of the exhaust groove 101 so as to directly inject gas into the abdominal cavity 10. Can be set. Although not shown, an installation groove (not shown) into which the gas injection pipe 400 may be fitted may be further formed on the inner surface of the stem 100. Therefore, since the gas injection pipe 400 is provided on the inner side of the stem 100 and is structurally securely divided from the exhaust groove 101 formed on the outer surface of the stem 100, the gas injection pipe 400 exits from the gas injection pipe 400. The gas does not flow directly to the outside and flows into the exhaust groove 101 through the abdominal cavity 10.
