Description

Cervical clamp capable of being assembled with endoscope

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a cervical clamp capable of being assembled with an endoscope.

Background

It is known that, in the conventional gynecological hysteroscopy, various surgical operations are performed by dilating the vagina with a speculum and then clamping the cervix with cervical clamps. However, in the current vaginal endoscopy technique, which is also called a non-contact hysteroscopy technique, the use of a vaginal speculum and a cervical clamp is not required in the whole process, so that the discomfort of a person to be examined is reduced to the maximum extent, but because the vaginal speculum and the cervical clamp are not used in the vaginal endoscopy hysteroscopy technique, the uterus cannot be expanded, and therefore, only a thinner endoscope body can be used for outpatient hysteroscopy. In clinical work, many patients need not only outpatient hysteroscopy but also further surgical treatment, so the patients need to be converted into conventional hysteroscopy surgical treatment again, and the rupture of hymen caused by using a vaginal speculum and performing surgical operation on the asexual life patients is also a difficult factor of the conventional hysteroscopy surgery for some special populations such as obesity, double-lower-limb abduction movement disorder, vaginal stenosis, cervical exposure difficulty and the like.

Therefore, if a visual cervical clamp is provided, the cervical clamp can be placed into the cervical clamp under direct vision to accurately clamp the cervix and visually expand the uterus under direct vision, and the uterus can be expanded without a vaginoscope, so that the hysteroscope operation is performed, and the application range of the vaginal endoscope is obviously widened.

The device can clamp the cervix accurately and expand the uterus under direct vision through the guidance of an optical system, which is irreplaceable for the image displayed after B-ultrasonic guidance. Because the resectoscope with larger diameter can enter the uterine cavity for operation only after full uterine dilatation through the cervical canal, and simultaneously, the operations of clamping and dilating the uterine neck and the like can be carried out without putting a vaginal speculum, the hysteroscope operation of the young girls needing diagnosis and treatment and the sexually-inactive women is not limited to hysteroscope examination, and can be applied to the hysteroscope operation (such as diseases of submucosal hysteromyoma, multiple endometrial polyps, intrauterine tumors and the like), thereby widening the range of operation treatment. Brings good news to women who are obese, have dysfunction in abduction of the lower limbs, have narrow vagina and have difficulty in exposing the cervix.
