[0028] Please refer to Figures 1-3 , the present utility model provides a disposable multi-channel single-port laparoscopic trocar, which is provided in a sterile state, sterilized by ethylene oxide, and is for single use. The disposable multi-channel single-port laparoscopic trocar includes an incision protection sleeve 26, an incision dilator 13 and a multi-channel operation platform assembly. By expanding the incision protection sleeve 26 placed in the incision through the incision dilator 13, it can effectively prevent the incision from closing. The surgical instrument passes through the multi-channel operation platform assembly, the incision dilator 13, and the incision protection sleeve 26 and enters the incision, facilitating the operator to observe the situation inside the incision for laparoscopic surgery.

[0029] Please refer to Figures 2-3 , the incision protection sleeve 26 has a protection channel. Both ends of the protection channel penetrate through the two end faces of the incision protection sleeve 26 respectively, and a first opening and a second opening are formed on the two end faces of the incision protection sleeve 26. The first opening is for placement inside the incision, and the second opening is for placement outside the incision. In this way, after the surgical instrument enters the protection channel from the second opening, it enters the incision through the first opening. While protecting the incision tissue 360° and preventing incision infection, it can also stabilize and broaden the incision view. The incision protection sleeve 26 is made of a film material, and can be manually flipped to curl and shorten or stretch and elongate according to the surgical needs to adjust the channel length, and has uniform radial tension, which is especially suitable for small incision surgery. Specifically, the incision protection sleeve 26 is provided with an insertion ring 16 at the first opening and a connection ring 15 at the second opening. More specifically, the insertion ring 16 is circumferentially joined with the incision protection sleeve 26 along the first opening, and the connection ring 15 is circumferentially joined with the incision protection sleeve 26 along the second opening.

At least part of the area on the support member 25 is a visible area, and the visible area can correspond to the position of the second opening. By having a multi-channel operation platform main body and a support member 25 in the multi-channel operation platform assembly and setting a visible area on the support member 25, the operator can observe the situation inside the incision through the visible area to better complete the operation. Specifically, the diameters of the two groups of bases and the sleeves 3 are all different, so that the diameters of the formed operation channels are also different, so that the two groups of operation channels can be entered by surgical instruments with different diameters. This multi-channel design can effectively reduce the mutual collision of instruments. Of course, the number of bases can also be set to more than two groups, and the number of sleeves 3 matches the number of bases.

[0032] During specific implementation, please refer to Figures 1-4 , when the support member 25 is connected with the incision dilator 13, the visible area corresponds to the position of the dilation opening, so as to correspond to the position of the second opening.
