When the air bag sealing device is used, the air bag assembly 9 is sleeved outside the stop levers 6, the plug-in pipelines 27 are inserted into the corresponding air holes 10 below, and the sealing rings 24 play a sealing role in the air holes 10, so that the sealing performance between the plug-in pipelines 27 and the air holes 10 is improved, and gas leakage is not easy to occur. The insertion rods 16 are then inserted into the first insertion hole 11 and the second insertion hole 12, respectively, so that the stop lever 6 can both internally support the airbag module 9 and define the position of the airbag module 9 in the vertical direction by means of the insertion rods 16. The air bag component 9 is more stable in use, is not easy to fall off, and is more efficient and safer in the supporting process of the tool setting opening.

After the incision on the body of the patient is formed, the air outlet end of the external air pump is connected with the air pipe connector 3, all the valves 2 are opened, and all the supporting air bags 14 are filled with air in advance, so that the air bag assembly 9 is unfolded. Then the air bag component 9 is plugged into the incision of the operation, the air pump is used for filling air into the air bag component 9, the volume of the air bag component 9 is increased, the inner wall of the incision is gradually expanded, and then medical staff can smoothly check the condition of the focus inside the body of the patient through the top seat 1 and the inner cavity of the air bag component 9. The body tissue at the bottom end inside the bottom of the knife edge can not shield the focus.

The air bag component 9 below can be swung by slightly shifting the top seat 1 in the operation, and the range of looking over at the focus inside the body of a patient can be enlarged under the condition that the incision is not enlarged after the air bag component 9 swings, so that the working efficiency of medical staff in the operation and the accuracy of the operation can be improved.

If the muscle or fat layer of the patient body is thick, the body tissues under the inner part of the operation incision are close to each other to influence the visual line of the operation. The bottom plate 5 can be pushed downwards, and then the air bag component 9 can be driven to move downwards, so that the depth of knife edge expansion is increased. When the bottom plate 5 moves downwards, the moving rod 17 moves downwards along with the moving rod, the return spring 20 is stretched, then the limiting bolt 4 is screwed to move downwards until the bottom end of the limiting bolt 4 is abutted to the top end of the top plate 21, the top plate 21 is blocked by the limiting bolt 4, the bottom plate 5 can keep the set position and cannot be changed easily, and the airbag module 9 can keep stable support after being unfolded downwards. When the bottom plate 5 contracts upwards, the limiting bolt 4 is screwed upwards, and the return spring 20 can pull the bottom plate 5 to move upwards. Because the supporting air bag 14 is limited by the two inserting rods 16, the top of the air bag assembly 9 cannot be separated from the bottom of the top seat 1, the air pump can be kept to charge air into the air bag assembly 9, and the air cannot leak outwards.

If a certain position of the inner wall of the incision needs to be further expanded to support in the operation, the valve 2 at the air inlet of other supporting air bags 14 can be closed, so that air can only enter the supporting air bags 14 to be further expanded, the incision can be expanded in the operation in an all-around way, the expansion opening can be finely adjusted according to actual requirements, the incision is prevented from being expanded, and unnecessary injury to the body of a patient is avoided.

Utilize air bag subassembly 9 to support, can keep the compliance, avoid causing the damage to health tissue in the tool setting mouth, can play fine supporting role again, support comparatively softly, the difficult phenomenon that the edge of a knife is torn appears. The resistance groove 13 can be clamped with body tissues in the inner wall of the incision, so that the friction force is increased, and the air bag assembly 9 is prevented from falling off from the incision.

The driving gear 23 can be twisted to rotate in the operation to drive the toothed plate 7 to move, so that the size of the notch on the top seat 1 can be adjusted, the channel observed by medical staff is enlarged, and the accuracy in the operation is improved. And some medical instrument pipelines needing to enter the incision in the operation can enter from the notches and are clamped through the buckles 26, so that the stability is improved, and the operation is more convenient and efficient. When in use, the air bag assembly 9 can be freely detached and replaced, and the air bag assembly 9 cannot be used due to damage or other reasons in use, so that the air bag assembly can be replaced, and the use cost is saved.

The preferred embodiments of the invention disclosed above are intended to be illustrative only. The preferred embodiments are not intended to be exhaustive or to limit the invention to the precise embodiments disclosed. Obviously, many modifications and variations are possible in light of the above teaching.
