An outer sleeve 5 is detachably sleeved on the catheter 3 . Preferably, the outer sleeve 5 is of a hard structure; the length of the outer sleeve 5 is greater than 2/3 of the length of the catheter 3 .

Specifically, as shown in FIGS. 3 and 4 , the connecting portion of the main airbag 1 and the suspension bag 2 is a separation surface 12 , the suspension air pipe 21 is arranged on the separation surface 12 , and the traction tube is arranged at the upper end of the separation surface 12 . By setting the separation surface 12, to increase the contact surface between the main airbag 1 and the suspension bag 2, avoiding the lateral movement of the suspension bag 2 relative to the main airbag 1 that is not controlled by the traction line 22, and improving the controllability of the movement of the suspension bag 2 sex.

As shown in Figure 8, the suspension trachea 21 and the main trachea 13 are provided with a trachea valve plate 24 adjacent to the position of the conduit 3, the trachea valve plate 24 is an elastic structure, and is kept in a normally open state without external force; the trachea valve plate 24 is adjacent to One side of the conduit 3 is respectively connected to the valve traction wire 25 , and the end of the valve traction wire 25 passes through the connecting block 35 and is connected to the traction end 41 . By pulling the movement of the trachea valve plate 24, the suspension trachea 21 and the main air pipe 13 are blocked and penetrated, so that the suspension bag 2 and the main air bag 1 are inflated and deflated separately from the trachea port 39 .

An inner diaphragm 31 is arranged in the catheter 3, and the suspension bag pulling wire 22 is separated from the valve pulling wire 25 and the trachea port 39 by the inner diaphragm 31, so as to prevent the pulling of the suspension bag pulling wire 22 from causing the main airbag 1 and suspension bag 2 internal gas overflow; suspension bag 2 traction line 22 is located on the side of the inner diaphragm 31 away from the trachea opening 39; Both the pulling wire 22 and the valve pulling wire 25 pass through the connecting block 35 .

One end of the trachea valve plate 24 adjacent to the conduit 3 is fixedly connected to the annular limiting flange 23 . The moving position of the trachea valve plate 24 is limited by the limiting flange 23 to play a sealing role. When the trachea valve plate 24 abuts against the limiting flange 23, the suspension trachea 21 and the main trachea 13 can be blocked.

Preferably, because the bottom of the trachea valve plate 24 is made of elastic material, when no external force acts on it, it has an inclination angle of 45 to 60 degrees with the limiting flange 23 and remains open so that the trachea valve plate 24 is not pulled by the valve plate. When the tension of the line 25 acts, the unimpeded state of the main air pipe 13 and the suspension air pipe 21 is maintained.

A support ring 32 is provided on the upper part of the catheter 3 adjacent to the main airbag 1, and the support ring 32 is made of hard material.

The upper end of the outer sleeve 5 is provided with a limit groove 52 that cooperates with the abutment block 34, and cooperates with the abutment block 34 through the limit groove 52. , restricting the lateral movement of the outer sleeve 5 . Since the catheter 3 is made of soft material and the outer sleeve 5 is made of hard material, the simple cooperation of the two makes it difficult to achieve a sufficient position-limiting effect. Through the structural cooperation of the support ring 32, the abutment block 34, the outer sleeve 5, and the limit groove 52, they jointly play the role of limiting the relative position of the outer sleeve 5 and the catheter 3, and achieve reasonable and sufficient exposure in actual operation.

By setting the matching structure of the limit block 36 and the limit sleeve 37, and setting the magnet block 38 therein, when the magnet block 38 on the limit block 36 and the limit sleeve 37 is opposite, under the magnetic force, the limit block 36 and the limit sleeve 37 can keep the relative position fixed for a period of time, thereby keeping the relative position of the pulling wire 22 fixed, after pulling the suspension bag 2 to the target angle, the position of the suspension bag 2 is guaranteed to be fixed, so as to facilitate further observe. Or after the suspension bag 2 and the main air bag 1 are inflated, ensure that the position of the trachea valve plate 24 is relatively fixed, so as to avoid the internal gas from overflowing.

During the operation, when it is necessary to move the suspension bag 2 up and down again to expose the position of the abdominal cavity, since the positions and angles of the suspension bag traction line 22 and the connecting block 36 are fixed, by rotating the suspension bag traction line 22 or the traction section 41, the The relative rotation of the limit block 36 and the limit sleeve 37 is until the magnet blocks 38 on the two are separated from each other, and the traction line 22 corresponding to the main air pipe 13 or the suspension air pipe 21 is automatically reset under the elastic action of the air pipe valve plate 24, The trachea is opened to realize the effect of inflation and deflation; the traction line 22 connected to the suspension bag 2 can be adjusted by pulling its upper and lower angle positions relative to the main air bag, and when adjusted to the target position, the stop block 36 is rotated to make the limit The position block 36 fits with the magnet block 38 on the position-limiting sleeve 37 to re-fix the relative position of the two.

When the operation is over, when it is necessary to deflate the suspension bag 2 and the main airbag 1, the same operation as above can be adopted to break away from the tight contact between the trachea valve plate 24 and the limiting flange 23, and to realize deflation. The device is then removed to complete the procedure.
