Abstract

The invention relates to the technical field of medical instruments and provides cervical dilation equipment. The cervical dilation equipment comprises a cervical dilator and a positive-negative pressure generator. The cervical dilator comprises a cervical guide-in tube, a cervix opening dilation balloon and a cervix dilation balloon. The tail end of the cervical guide-in tube is connected with aconnection seat, and a first tube and a second tube are arranged in the cervical guide-in tube. One end of the first tube penetrates the cervical guide-in tube to communicate with the cervix opening dilation balloon while the other end is connected with the connection seat; one end of the second tube penetrates the cervical guide-in tube to communicate with the cervix dilation balloon while the other end is connected with the connection seat. The connection seat comprises a first passage, a second passage and a third passage. The positive-negative pressure generator comprises a water injectionmechanism, a negative-pressure suction mechanism and a connection plug. The connection plug is provided with a first insertion needle, a second insertion needle and a third insertion needle.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a cervical dilation device. Background technique

[0002] Now the traditional cervical dilation technique requires a vaginal examination before dilating the cervix to understand the tendency of the uterus. The probe is used to detect the depth of the uterine cavity, and then the cervix is ​​dilated sequentially with a metal dilator. However, due to the hard material of metal instruments, it is easy to damage the uterine cavity to form sinuses, and even perforate. And because of intrauterine adhesions, cervical canal adhesions, and excessive tilt of the uterus to form an included angle, it is often difficult to enter the probe. Contents of the invention

[0003] The object of the present invention is to provide a cervical dilation device, so as to alleviate the technical problem that the existing metal cervical dilator will cause harm to the patient during use. [000...
