Referring to fig. 6, fig. 6 is a schematic diagram illustrating a method and a state of use of the single port laparoscopic instrument system for V-NOTES surgery according to the present invention. When in use, the proximal end of one connecting sleeve 12 is cut off, then the air bag 2 is put into the elastic connecting member body 11 from the distal end opening of the elastic connecting member body 11, the air bag body 21 is made to be inclined in the elastic connecting member body 11, and then the proximal end of the inflation tube 22 is taken out from the proximal end opening of one connecting sleeve 12 and fixed by the fixing member 4, for example, a silk thread is wound outside the connecting sleeve 12. The proximal end of the preferred connector sleeve 12 is then cut out in a corresponding (e.g., three) number and location, depending on the number of surgical instruments to be used, and the proximal end of each cut-out connector sleeve 12 is assembled with a channel body 31. Specifically, the channel body 31 is inserted into the connection sleeve 12 such that the distal end of the channel body 31 is flush with the distal end of the connection sleeve 12, and then the channel body 31 and the connection sleeve 12 are secured using the securing member 4, such as by winding wire around the outside of the connection sleeve 12. After the assembly is completed, the elastic connecting piece body 11 is firstly placed into the natural cavity 6 to a proper depth, the proximal end of the inflation tube 22 is connected with the air injector for inflation, the interior of the air bag body 21 is inflated and expanded, the elastic connecting piece body 11 is supported, the vaginal wall is expanded, and meanwhile, the elastic connecting piece body 11 is pressed tightly to fix the device, so that a closed single-hole state is formed. The carbon dioxide gas injection tube 5 is connected to the smoke exhaust tube 322 of one of the surgical instrument channels 3 while the elastic connection member 1 is compressed to expand. One of the surgical instrument channels 3 is placed into a laparoscopic source lens. Other surgical instruments 3 are respectively placed into surgical operation instruments such as separating forceps, needle holder, ultrasonic knife, etc. through the surgical instruments channel inlets, and the smoke generated by the electrical operation in the surgical process can be discharged from the smoke discharge tube 322 by opening the valve 323, so as to ensure a clear surgical field. That is, in the use state, the air bag body 21 of the air bag 2 is inclined and positioned in the elastic connecting piece body 11 of the elastic connecting piece 1, and the proximal end of the inflation tube 22 of the air bag 2 extends out from the connecting sleeve 12 and is fixedly sealed by the fixing piece 4; the channel body 31 of the surgical instrument channel 3 is inserted into the other connecting sleeve 12, and the distal end of the channel body 31 is flush with the distal end of the corresponding connecting sleeve 12 and is fixedly sealed by the fixing piece 4; the air bag body 21 of the air bag 2 is in an inflated and expanded state, and the elastic connecting piece body 11 is pressed and fixed on the vaginal wall by the air bag body 21; the elastic connecting piece 1 is in an expanded state, and the distance between the connecting sleeves 12 is increased; the valve 323 is in an open state for discharging smoke.
It should be noted that, herein, the "proximal end" refers to an end closer to the operator during the operation, whereas the "distal end" refers to an end farther from the operator during the operation.
The elastic connection 1 has elasticity and thus has several advantages: firstly, after the pneumoperitoneum is formed by inflating the abdominal cavity, the elastic connecting piece 1 expands to be larger, each connecting sleeve 12 also expands, and the distance between the connecting sleeves 12 becomes larger, so that the operation of each surgical instrument is not interfered with each other; secondly, when operating the surgical instrument, the operator can realize the axial movement of the human body of the surgical instrument and the radial offset to various angles, so that the flexibility is high; thirdly, can deform, be convenient for put into and take out. The arrangement and spacing of the individual connection sleeves 12 in the proximal end region of the elastic connector body 11 is not limited, and may be arranged in one row, two rows, or other arrangements. The proximal end of the connection sleeve 12 is designed to be closed, facilitating the operator's choice of cutting the appropriate location and number of connection sleeves as desired without affecting the overall tightness. The number of connecting cannulas 12 is preferably four or more to meet the requirements of V-NOTES surgery.
The air bag 2 is used for effectively fixing the elastic connecting piece 1 in an inflated state to ensure that the elastic connecting piece is not easy to fall off, form a good sealing environment and maintain a pneumoperitoneum state, and is convenient for controlling the size of a cavity channel by regulating and controlling the inflation quantity so as to meet different operation demands. The air bag 2 is designed to be inclined in the elastic connecting piece 1 when in use, so that the elastic connecting piece 1 with a larger length can be fixed in the axial direction of the cavity, the fixing effect is better, and the air bag does not occupy excessive cavity space and does not hinder the operation of the surgical instrument. The balloon 2 is preferably made of a material having a certain hardness so as to be easily inserted.

The inner diameter of the handle 32 is larger than that of the channel body 31, and the smoke exhaust pipe 322 is arranged on the side wall, so that smoke formed by electric mechanical operation in the abdominal cavity can be timely and efficiently exhausted, and a clear operation field is always maintained.
The fixing piece 4 is used for fixing the connecting sleeve 12 and the inflation tube 22 or fixing the connecting sleeve 12 and the channel body 31 so as to ensure the tightness of the inside of the cavity. The fixing member 4 is not limited to a wire but may be a loop having elasticity or the like.
The number of the connecting sleeve 12, the surgical instrument channel 3 and the fixing piece 4 is not limited to the embodiment, and can be set according to the requirements, but the embodiment is the best, so that the operation of abdominal inflation of the clinical V-NOTES surgery and the operation of the conventional surgical instruments can be satisfied.

The handle 32 has a surgical instrument channel inlet 321 in the center of the proximal end, a smoke exhaust pipe 322 on the side wall, and a valve 323 on the smoke exhaust pipe 322. The surgical instrument channel 3 can be integrally formed, is hard and can be made of transparent medical high polymer materials.
That is, the shape of the handle 32 is not limited to a cylindrical shape, but may be other shapes such as a prismatic shape, so long as the area of the distal end face of the handle 32 is ensured to be larger than the area of the proximal end face of the channel body 31, so as to ensure that the handle 32 has a larger inner cavity, and the smoke is discharged conveniently. The handle 32 is still optimally cylindrical and is most convenient for the operator to hold.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and additions may be made to those skilled in the art without departing from the method of the present invention, which modifications and additions are also to be considered as within the scope of the present invention.
