But the technical proposal disclosed by the utility model has the defects of poor air tightness. During the abdominal surgery, a doctor inflates the abdominal cavity of a patient with gas under a certain pressure to facilitate observation and operation of instruments, and at this time, since the inside of the glove is communicated with the abdominal cavity of the patient, a certain gas pressure is also present inside the glove, and although a continuous small leakage of the inflated gas is allowed during the surgery, if the leakage is too fast, the surgery is troublesome and even the life safety of the patient is compromised. The technical scheme disclosed has higher requirements on experience of a maker in practice, otherwise, the problem of too fast gas leakage is easy to occur, but if the surgical instrument is too tightly matched with the instrument penetrating pipe (3), the surgical instrument is dragged by the gloves in the moving process, so that the medical staff is difficult to grasp and make the product.
There is therefore a need for improvements in the structure and method of making existing access channels.

Detailed Description
The present invention will be further described with reference to the following examples.
Example 1
As shown in fig. 1 to 5, the access passage of the single port laparoscope of the present embodiment includes: a glove 11, a tube 12 and a binding 13.
Wherein, the glove-shaped member 11 is an operating glove, and the whole glove-shaped member is made of thin-wall elastic airtight material; the tube 12 is a fitting on a medical delivery tube; the binding 13 is a medical suture.
As shown in fig. 1, 5 fingers 111, 112, 113, 114, 115 are formed on the glove member 11, one or more of which may be optionally modified to form a tool channel as desired. The present embodiment is to be modified by the finger 113 located at the center.
as shown in fig. 1, 2 and 3, the finger 113 is cut transversely from the finger tip to form a through hole 14, and then about 3/4 of the transversely cut finger is turned inside the glove 11 to form the instrument channel 15, and the turned-in portion is passed through the lumen of the tube 12, which is now inside the glove 11. The remaining approximately 1/4 of the transected finger remains on the outside of the glove 11, at the location of the finger, which is secured to the tube 12 by the binding 13.
As shown in fig. 4 and 5, when the access passage is filled with gas under a certain pressure and the surgical instrument 16 is inserted, the instrument passage 15 becomes narrower and narrower by the gas pressure, and finally comes into close contact with the outer surface of the surgical instrument 16, and the higher the gas pressure is, the closer the instrument passage is. In use, surgical instrument 16 may also be coated with a medical lubricant to reduce friction between surgical instrument 16 and instrument channel 15.
Example 2
As shown in fig. 6 and 7, the present embodiment is different from embodiment 1 in that: the opening of the through hole is turned back to partially cover the pipe 22, the turned back portion of the opening of the through hole is fixed to the pipe 22 by the second binding member 27, and the air passing hole 221 is formed in the pipe 22. The second binding 27 is also a medical suture.
As shown in fig. 8 and 9, when gas is injected into the inlet passage, the gas passes through the gas holes 221 and enters a space between the tool passage 25 and the inner wall of the tube 22, which is referred to as a passage expansion chamber 28. As the gas pressure increases, the volume of the channel expansion chamber 28 increases and the instrument channel 25 becomes narrower until it is hermetically sealed. After the surgical tool 26 is inserted into the tool passage 25, the tool passage 25 is always closely attached to the outer surface of the surgical tool 26 to prevent the gas in the glove member from leaking to the outside.
This structure reduces the drag force on the surgical instrument 26 compared to the structure of example 1, and makes the operation of the surgical instrument 26 more flexible and convenient.
Example 3
as shown in fig. 10 and 11, the present embodiment differs from embodiment 2 in that: a flange 321 is also formed at one end of the pipe member 32 near the through hole. The flange 321 prevents the reversed part of the opening of the through hole from being loosened.
Example 4
this embodiment is a method for manufacturing an access channel of the single port laparoscope of embodiment 1.
the method comprises the steps of penetrating 1 finger part of a glove-shaped part through an inner cavity of a pipe fitting, transversely cutting the tail end of the finger part to form a through hole, turning the glove-shaped part inside and outside, and fixing the transversely cut finger part and the pipe fitting together from the outside by using a binding piece.
The manufacturing method can simply manufacture the access channel with better effect than the existing access channel.
Example 5
