Sims rectal speculum experience

Does anyone have experience with the sims rectal speculum? (search for: "sims speculum fenestrated") The moment after insertion and especially when I pull it out my sphincter muscle spams and it's very painful as it forces the speculum closed and tissue gets pinched between the blades. Similar experience anyone? How to avoid this, prevent this, thoughts, comments?

I only have bad experience , I hate it I throw it away after two times.

All other speculums are better.

Exactly, thanks for the response @julle1976 I was thinking the same, like..how can anyone use this? Does it get used on real patients? Perhaps it's only meant to be used during surgeries (during which the patients are usually under anesthesia or/and muscle relaxants).

I gave mine away for the same reason. It should be removed before being completely closed. It is much easier to use on another person with careful understanding than on yourself. Mistress was grateful to receive it and I was nicely rewarded for the gesture.

I have a number of rectal speculums, you just have to make sure that when you squeeze open the blades, if the patient feels any discomfort to close them slightly. As for the withdraw, I always keep the blade slightly open to avoid pinching.

For me the Collins speculum and plastic gyno speculum always working best. I know what you're talking about in your post. It's best to remove it slowly, when it's slightly open.
