Description

Preoperative uterine dilator

Technical Field

The utility model relates to the technical field of hysteroscopic surgery, in particular to a preoperative uterine dilator.

Background

Hysteroscopy is so advanced, but two problems are faced when performing hysteroscopy. The first problem is that the cervical canal of most women, especially the infertile women, is narrow, and the hysteroscope body cannot be directly inserted, so the cervix needs to be moderately dilated before the operation to facilitate the insertion of the hysteroscope body during the operation. At present, the cervical softening effect is mainly achieved by softening the cervix clinically through a vaginal medicine application method, but the medicines do not directly act on the cervix, so that the cervical softening effect is not exact and some side effects exist. The second problem is that the cervical canal of a female who has born a birth, especially a female who has been born in a multiple natural birth, is relatively loose, and when the hysteroscopy operation is performed on the female, a large gap still exists between the hysteroscopy body and the cervical canal, so that uterus swelling liquid is easy to leak, the uterus swelling pressure is insufficient, the uterine cavity cannot be completely swelled, and the diagnosis and treatment of uterine cavity lesion are influenced.

At present, the endoscope body is tightened by overlapping and clamping redundant cervical tubes of the cervical clamps to prevent the leakage of uterine distention liquid clinically, but the treatment measure needs one hand of a main knife or an assistant to fix the cervical clamps, which limits and influences the operation flexibility of the main knife, and the cervical clamps often slip. Meanwhile, due to the fact that the cervical clamp is clamped for a plurality of times and for a long time, the possibility of damaging organs around the cervix, such as the bladder, the urethra and the rectum, is greatly increased. Therefore, in summary, the two inevitable 'small' problems in practical operation greatly affect the accuracy, safety and effect of the operation, and therefore, the existing requirements are not met, and a preoperative uterine dilator is provided.
