Problems solved by technology

[0002] In many uterine operations, the cervix needs to be dilated, and the cervix is ​​often small, and medical instruments cannot be inserted into the cervix.
Existing cervical dilators are various rod-type devices of different thicknesses, which require repeated operations to allow the contractile cervix to expand naturally under external pressure, which is very inconvenient; another rod-type dilator contacts and rubs against the inner wall of the cervix many times. , it is easy to cause cervical damage, and the expansion effect is very poor

Abstract

The invention belongs to dilators and particularly relates to a cervical dilator. The cervical dilator comprises a dilating head, a dilating frame, an inner core, a connecting rod and bilateral side handles which are sequentially connected mutually; the rear end of the dilating head is connected with the dilating frame; the dilating head and the dilating frame are in circular hollow structures; the dilating frame comprises an upper portion fan-shaped side, a lower portion fan-shaped side and symmetrical dilating sheets on bilateral sides. According to the cervical dilator, the dilating effect is good, the utilization method which is similar to that of original pliers and scissors is convenient, a cervix uteri is externally opened through the dilating sheets, collecting and releasing functions of opening are achieved according to the principle of a fan-shaped shed-shaped support and in combination with matching of the inner core and the dilating frame through flexible hinged supporting points installed at support joints, cervical damage caused by normal dilation is avoided.

Description

technical field [0001] The invention belongs to dilators, in particular to a cervical dilator. Background technique [0002] In many uterine operations, the cervix needs to be dilated, and the cervix is ​​often small, and medical instruments cannot be inserted into the cervix. Existing cervical dilators are various rod-type devices of different thicknesses, which require repeated operations to allow the contractile cervix to expand naturally under external pressure, which is very inconvenient; another rod-type dilator contacts and rubs against the inner wall of the cervix many times. , It is easy to cause cervical damage, and the expansion effect is very poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an easy-to-use cervical dilator aiming at the shortcomings of the prior art. [0004] In order to achieve the purpose of the present invention, the following technical solutions are adopted: a cervical dilat...
