[0046] Furthermore, a lifting ring 231 is fixedly connected to the upper end of the spring 230, for example, by bonding or tight fitting; the lifting ring 231 is sleeved on the inner wall of the sealing sleeve 110, and an inner ring 111 is provided on the inner wall of the sealing sleeve 110 near its top, and the lifting ring 231 is clamped in the cavity above the inner ring 111, thereby supporting the lifting ring 231 to pull the spring 230 to rebound and reset; the inner diameter of the inner ring 111 is larger than the major diameter of the spring 230, so that the spring 230 does not touch the inner side of the inner ring 111 and interfere with the movement when it bounces.

[0047] In addition, a liquid absorbent group 300 is provided on the outer side of the top of the wound cover 100 to absorb waste liquid overflowing from the abdominal wound and the wound cover 100; the liquid absorbent group 300 includes a round absorbent cotton 310 and a liquid storage bag 320 covering the absorbent cotton 310; the absorbent cotton 310 has a central opening and is connected to the wound cover 100 so that it can contact the abdominal wound and absorb liquid in time, and is wrapped and stored in the liquid storage bag 320 to avoid overflow; a number of liquid outlet heads 322 are provided at equal intervals on the outer side of the liquid storage bag 320, and a rubber plug is provided inside the liquid outlet head 322, and the rubber plug is opened to release the liquid absorbed by the absorbent cotton 310 inside the liquid storage bag 320.

[0048] Furthermore, a liquid inlet 321 is provided at the center of the liquid storage bag 320, and the inner diameter of the liquid inlet 321 is larger than the central hole of the liquid absorbent cotton 310, and the upper and lower edges of the liquid inlet 321 are bonded to the upper and lower surfaces of the liquid absorbent cotton 310, so that the inner circle of the liquid absorbent cotton 310 absorbs the liquid and penetrates into the liquid storage bag 320 along its own cotton threads for temporary storage;

[0049] The liquid storage bag 320 is made of PP material and is in the shape of a closed membrane on the outside and is connected to a plurality of liquid outlet heads 322. The outer diameter of the liquid storage bag 320 is larger than the outer diameter of the absorbent cotton 310 to form a liquid storage cavity. The outer sleeve of the liquid outlet head 322 is provided with a drainage tube 323, through which the waste liquid is drained out of the patient's body.

[0050] It is worth noting that, in order to enable the liquid-absorbing cotton 310 to discharge waste liquid in time, an auxiliary pressing piece 400 is provided on one side of the sealing sleeve 110, and the auxiliary pressing piece 400 includes a square pressing handle 410 and a pressing roller 430 suspended below the pressing handle 410; a collar 411 sleeved with the outer wall of the sealing sleeve 110 is provided on one side of the pressing handle 410, and the central axis of the pressing roller 430 points to the center of the collar 411; a supporting ring 113 for limiting the collar 411 is provided on the outer side of the bottom of the sealing sleeve 110; by pressing the pressing handle 410 and rotating it around the sealing sleeve 110, the pressing roller 430 is used to roll on the liquid storage bag 320, thereby squeezing out the waste liquid absorbed by the liquid-absorbing cotton 310 and discharging it from the drainage tube 323;

[0051] A lever 420 is provided on the top surface of the outer end of the pressing handle 410 so that the pressing handle 410 can be rotated by pinching the lever 420; a suspension rod is fixedly connected to the outer end of the lever 420 and the lower end of the suspension rod is rotationally connected to the pressing roller 430 via a pin.

[0052] When the wound holding support with waste liquid absorption function for laparoscopic minimally invasive surgery of the present invention is used, the assembled wound cover 100 is clamped inside and outside the abdominal wound as a whole, and after the expansion bag 200 is lifted, the plurality of pulling posts 122 are pulled by the plurality of pull rods 222 to expand the plurality of membrane notches 121 to form a surgical incision, so that surgical instruments can be inserted into the abdominal cavity for surgery; during the surgery, liquid will overflow into the expansion bag 200, and at this time, the waste liquid needs to be cleaned to provide a good environment for the surgery; before sucking out the waste liquid, the expansion bag 200 is pressed down and the linkage cover 220 is rotated to be threadedly connected and positioned with the sealing cover 110, so that the plurality of pull rods 222 pull the plurality of pulling posts 122 to twist and close the plurality of membrane notches 121, so as to seal the internal space of the expansion bag 200, and then the suction needle is inserted from the valve seat 210 to suck out the liquid generated during the surgery;

[0053] In addition, liquid may overflow between the wound cover 100 and the abdominal wound. By rotating the pressure handle 410 mounted on the outside of the sealing cover 110 and using the pressure roller 430 at the bottom of the pressure handle 410 to roll on the liquid storage bag 320, the waste liquid absorbed by the absorbent cotton 310 placed at the wound can be squeezed out and discharged from the drainage tube 323 in time, thereby ensuring a clean environment required for the operation.
