Fig. 1 and Fig. 3 are please referred to, one end of the silicone tube 13 towards the conduit 10 is tied up by filament in the card slot
In 113, the bottom of the inner cavity of the silicone tube 13 is equipped with positioning region 131, the end and the positioning region 131 of the full head 12
Connection, and the end of the silicone tube 13 is extended.
Preferably, the silicone tube 13 forms silica gel sticking part 132, the silica gel fitting towards one end of the conduit 10
The effect in portion 132 is the end for preventing filament from skidding off the silicone tube 13.
Fig. 2 and Fig. 3 are please referred to, further, the positioning region 131 is the positioning column of an evagination, at this point, the full head
12 with full slot 125, the full slot 125 and the positioning column are recessed on the end face of the connecting pin of the positioning region 131
Connection.
Specifically, the cross sectional shape of the positioning column is circle in the present embodiment.Preferably, in other embodiments, institute
The cross sectional shape of positioning column is stated other than it can be circle, can also be triangle or rectangular, at this point, one side of the positioning column
Face can carry out axially position, on the other hand can also be positioned, be prevented between the silicone tube 13 and the full head 12
Axial-rotation and displacement slip.
Referring again to Fig. 3, the end of the silicone tube 13 is arc-shaped and outer diameter is gradually reduced, and arc-shaped can perform the operation
When reduce damage to uterine neck, outer diameter is gradually reduced so that the size that the silicone tube 13 enters in uterine neck incrementally increases, and is convenient for
Uterine neck adapts to protruding into for the silicone tube.
Specifically, the length of the silicone tube 13 is longer than the length of the connector in the present embodiment, and it is shorter than described fill
Be full of first 12 length.Preferably, the length range of the silicone tube 13 is 20mm~70mm, on the one hand in assembling process, is led to
The extension that the full head 12 realizes the length of the silicone tube 13 is crossed, that is, stretches the length of the silicone tube 13, so as to
Reduce the outer diameter of the silicone tube 13, i.e., so that reducing for the first time into the size of uterine neck, on the other hand can reduce the silica gel
Pipe 13 uses material.When the length of the silicone tube 13 is less than 20mm, the silicone tube 13 is drawn by the full head 12
After stretching, intensity increases and requirement is not achieved；When the length of the silicone tube 13 is greater than 70mm, the length of the silicone tube 13
The length of degree and the full head 12 is close, the effect of stretching is not achieved, i.e., the outer diameter of the described silicone tube 13 will not occur substantially
Variation, in addition, being increased using material for the silicone tube 13, increases cost.
It should be noted that in the present embodiment, the pressure-applying unit includes and the sequentially connected hose of the conduit, connector
With full device, the inside of the connector is equipped with check valve, is connected with pressure gauge on outer wall.By the full device to the expansion
It is filled with gas or liquid in component, gas or liquid charge are monitored by the pressure gauge.
Specifically, in the present embodiment, the full device is syringe, and the gas is air, the liquid be distilled water,
Purified water or physiological saline.
The utility model in use, will first suck gas or liquid in the full device, then with the connector
Connection, the full device fill Jie for what gas or liquid passed sequentially through connector, hose, conduit 10, connector 11 and full head 12
Matter channel 121 is slowly injected into the silicone tube 13, and the silicone tube 13 is externally expanded to realize the expansion to uterine neck, thus
Uterine neck, which is disposably slowly extended to, ensures the size that goes on smoothly of performing the operation, at the same by the pressure gauge real-time monitoring inside
The pressure condition of gas or liquid, when avoiding pressure too small, cervical dilatation is not in place, or avoids pressure change excessive, so that institute
The outer diameter variation for stating silicone tube 13 is excessive, leads to the damage to uterine neck.
To sum up, the utility model is connected through a screw thread, so that the connection between conduit 10, connector 11 and full head 12 is more
It is convenient；For the first time the extension for realizing the length of silicone tube 13 by filling head 12, on the one hand can reduce the outer diameter of silicone tube 13, i.e.,
Size into uterine neck reduces, and on the other hand can reduce silicone tube 13 uses material；It is passed sequentially through by gas or liquid
Conduit 10, connector 11 and filling medium channel 121 enter in the inner cavity of silicone tube 13, and silicone tube 13 is externally expanded to realize to palace
The expansion of neck mitigates the pain of patient so that uterine neck, which is disposably slowly extended to, ensures the size gone on smoothly of performing the operation, and reduces
Damage to cervical mucosa, to ensure to expand the safe and smooth progress of palace process.
