Specifically, the upper end of the suspension balloon traction wire 22 is connected with the edge of the suspension balloon 2, the suspension balloon traction wire 22 sequentially passes through the traction tube 11, the catheter 3 and the connecting block 35 from top to bottom, and the lower end of the suspension balloon traction wire 22 is connected with the traction end 41.

The catheter 3 is detachably sleeved with an outer sleeve 5. Preferably, the outer sleeve 5 is of a rigid structure; the length of the outer sleeve 5 is greater than 2/3 of the length of the catheter 3.

Specifically, as shown in fig. 3 and 4, the connection portion between the main airbag 1 and the suspension bag 2 is a partition surface 12, the suspension air pipe 21 is provided on the partition surface 12, and the traction pipe is provided at the upper end of the partition surface 12.

As shown in fig. 8, the positions of the hanging air pipe 21 and the main air pipe 13 adjacent to the catheter 3 are respectively provided with an air pipe valve plate 24, and the air pipe valve plates 24 are of elastic structures and are kept in a normally open state under the action of external force; the air pipe valve plate 24 is connected with the valve plate traction wire 25 at one side adjacent to the guide pipe 3, and the tail end of the valve plate traction wire 25 passes through the connecting block 35 to be connected with the traction end 41. By means of the movement of the traction air pipe valve plate 24, the blocking and penetration of the suspension air pipe 21 and the main air pipe 13 are achieved, and therefore independent inflation and deflation of the suspension bag 2 and the main air bag 1 are conveniently achieved through the air pipe ports 39.

An inner diaphragm 31 is arranged in the catheter 3, and the inner diaphragm 31 separates the suspension bag pulling line 22 from the valve plate pulling line 25 and the air pipe orifice 39, so that the air inside the main air bag 1 and the suspension bag 2 is prevented from being overflowed due to the pulling of the suspension bag pulling line 22; the traction wire 22 of the suspension balloon 2 is positioned on one side of the inner diaphragm 31 deviating from the air nozzle 39; the valve plate traction wire 25 is positioned on one side of the inner diaphragm 31 adjacent to the air pipe opening 39, and the suspension bag traction wire 22 and the valve plate traction wire 25 are both arranged on the connecting block 35 in a penetrating way.

One end of the air tube valve plate 24 adjacent to the guide tube 3 is fixedly connected with an annular limit flange 23. The movement position of the air pipe valve plate 24 is limited by the limiting flange 23, so that the air pipe 21 and the main air pipe 13 can be blocked when the air pipe valve plate 24 is abutted against the limiting flange 23.

Preferably, the air pipe valve plate 24 is made of elastic material, and forms an inclination angle of 45 degrees to 60 degrees with the limit flange 23 when no external force acts on the air pipe valve plate 24, so that the air pipe 13 and the suspended air pipe 21 are kept in an open state when the air pipe valve plate 24 is not acted on by the pulling force of the valve plate pulling wire 25.

The upper part of the catheter 3 is provided with a support ring 32 adjacent to the main balloon 1, the support ring 32 being of a hard material. An inner ring groove 33 matched with the upper end of the outer sleeve 5 is arranged on the inner side of the lower end of the support ring 32. The inner ring groove 33 is matched with the supporting ring 32 and is connected with the upper end of the outer sleeve 5, so that the longitudinal movement of the outer sleeve 5 is limited.

The guide pipe 3 is positioned in the inner annular groove 33 at the lower side of the supporting ring 32 and is symmetrically provided with the abutting blocks 34, the upper end of the outer sleeve 5 is provided with the limiting grooves 52 matched with the abutting blocks 34, and the lateral movement of the outer sleeve 5 is limited by the matching of the limiting grooves 52 and the abutting blocks 34. Because the catheter 3 is soft material, the outer sleeve 5 is hard material, and the two are simply cooperated, the effect of fully limiting is difficult to realize. Through supporting ring 32, butt piece 34 and outer tube 5, spacing groove 52 structural fit, play the effect of restriction outer tube 5 and pipe 3 relative position jointly, realize rationally fully exposing in the actual operation.

Before operation, since the main balloon 1, the suspension balloon 2 and the catheter 3 are all in a contracted state when not inflated, they can be extended into the abdominal cavity through the outer sleeve 5, and then each structure is inflated through the air tube port 39.

Specifically, when the main airbag 1 is inflated, the valve plate traction wire 25 corresponding to the main airbag 1 is kept unchanged, and the valve plate traction wire 25 corresponding to the suspension airbag 2 is stretched, so that the suspension air pipe 21 is closed and the main air pipe 13 is opened, and the main airbag 1 is inflated; when the specific suspension bag 2 is inflated, the positions of the valve plate traction wires 25 corresponding to the suspension bag 2 are kept unchanged, other valve plate traction wires 25 are stretched, the main air pipe 13 and other suspension air pipes 21 are closed, and the suspension air pipes 21 corresponding to the target suspension bag 2 are opened, so that the specific suspension bag 2 is inflated.

Through setting up the cooperation structure of stopper 36 and stop collar 37 to set up magnet piece 38 therein, when the magnet piece 38 on stopper 36 and the stop collar 37 is relative, under the magnetic force effect, stopper 36 and stop collar 37 can keep fixing between relative position in a period, thereby keep the relative position of pull wire 22 fixed, after pulling the suspension bag 2 to target angle, guarantee the fixed position of suspension bag 2, in order to facilitate further observation. Or after the hanging bag 2 and the main air bag 1 are inflated, the positions of the air pipe valve plates 24 are ensured to be relatively fixed, and the internal air is prevented from overflowing.

In operation, when the hanging bag 2 needs to be moved up and down again to expose the abdominal cavity, the positions and angles of the hanging bag traction wire 22 and the connecting block 36 are fixed, and the relative rotation of the limiting block 36 and the limiting sleeve 37 is driven by rotating the hanging bag traction wire 22 or the traction section 41 until the magnet blocks 38 on the two are separated from each other, and the traction wire 22 corresponding to the main air pipe 13 or the hanging air pipe 21 automatically resets under the elastic action of the air pipe valve plate 24, so that the air pipe is opened, and the air charging and discharging effect is realized; the traction wire 22 connected with the suspension bag 2 can adjust the vertical angle position of the traction wire relative to the main air bag through traction, and when the traction wire is adjusted to the target position, the limiting block 36 is rotated, so that the limiting block 36 is attached to the magnet block 38 on the limiting sleeve 37, and the relative position of the limiting block and the magnet block is fixed again.

When the operation is finished, the suspension bag 2 and the main air bag 1 need to be deflated, the same operation as the above is adopted, the air pipe valve plate 24 and the limit flange 23 can be separated from close contact, the deflation is realized, and then the device is taken out, so that the operation is finished.
