Danger, furthermore, it would be desirable to bestow certain forward thrust to uterus raising device, such requirement is more demanding to the outer wall support of uterus raising device,
So the external module for also resulting in uterus raising device is complex, when being pressed using man-hour manually hand-held, there is also biggish working strengths；
And more seriously, under the thrusting action, when uterus is cut off from from uterine neck, the moment, uterus raising device can pushing tow uterus
On the one hand Forward is possible to cause damaging surrounding tissue, on the other hand also exacerbating uterus falls into abdominal cavity or intrauterine group
Knit the risk that liquid stream enters abdominal cavity；
And using the uterine wall of present embodiment occlusion end A be engaged by the way of, due to using be engaged by the way of can be real
Now to the fixation in uterus, so not needing to ensure that uterus is fixed by bestowing pushing tow pressure, so can substantially reduce even
The requirement that jacking force is bestowed to uterus is avoided, so, the extruding to uterine wall is not only further reduced, but also also reduce
Requirement to uterus raising device outside operator or device also reduces equipment while medical staff's working strength is greatly reduced
Cost；Another further aspect also avoids uterus and is cut off from uterine neck the moment, the risk that uterus moves forward by thrust, further
The risk that uterus falls into abdominal cavity or intrauterine tissue fluid flows into abdominal cavity is reduced, operation safety is greatly improved.
It is as shown in FIG. 6 as preferred embodiment, be between the uterine wall occlusion end A and the gripper end
Dismountable connection.In the uterus raising device scheme of the application, it is component easy to wear that uterine wall, which is engaged end A, so uterine wall is stung
