Embodiment 1

[0104] Such as figure 1 As shown, the disposable micronon-invasive injection cervical dilator includes a dilator body, the dilator body includes an expansion part 2 and an assembly part 3, and the assembly part 3 is provided with a cavity, and the cavity extends to the expansion part 2 , for injecting liquid to promote the expansion of the expansion part 2.

[0105] Specifically in this embodiment, the cavity extends to at least half of the expansion part 2, and the inner diameter of the cavity gradually decreases, and a guide tube 4 is also provided in the cavity, and a liquid injection mechanism is used to inject liquid during use. The liquid outlet part communicates with the guide tube 4, and the liquid injection mechanism adopts a syringe.

[0106] A limiting boss is provided between the fitting part 3 and the expansion part 2 . A limit boss is set to ensure that only the expansion part 2 can enter the cervix, so as to avoid accidental contact of other parts with the ce...

Embodiment 2

[0118] Such as figure 2 As shown, the disposable micronon-invasive injection cervical dilator includes a dilator body, the dilator body includes an expansion part 2 and an assembly part 3, and the assembly part 3 is provided with a cavity, and the cavity extends to the expansion part 2 , the cavity is provided with a guide tube 4, the end of the assembly part 3 is detachably connected with a connector 6, one end of the connector 6 is detachably connected to the guide tube 4, and the other end is used for injecting liquid to promote the expansion of the expansion part 2.

[0119] Specifically in this embodiment, the assembly part 3 is provided with an assembly seat 5 outside, the connector 6 is clamped with the assembly seat 5, and the other end of the connector 6 is also clamped or screwed with an extension pipe 7, and the liquid is injected through the extension pipe 7 .

[0120] Specifically in this embodiment, the cavity extends to at least half of the expansion part 2, t...

Abstract

The invention relates to a disposable cervical dilator, in particular to a disposable minimally-invasive-noninvasive-injection cervical dilator and a processing method thereof. The disposable minimally-invasive-noninvasive-injection cervical dilator comprises a dilating rod body, the dilating rod body comprises a dilating part and an assembling part, the assembling part is provided with a cavity, and the cavity extends to the dilating part and is used for injecting liquid to promote expanding of the dilating part. The disposable minimally-invasive-noninvasive-injection cervical dilator and the processing method thereof have the advantages that a dilating rod is reasonable in structural design, high in expanding efficiency and adjustable in size after expanding, and dilating is carried out as required; the cervix can be dilated to the cervix required by a line hysteroscope in transitory time (30 s), and the disposable minimally-invasive-noninvasive-injection cervical dilator is quite convenient to clinically use.

Description

technical field [0001] The invention relates to a disposable micronon-invasive injection cervical dilator and a processing method thereof, belonging to the technical field of medical devices. Background technique [0002] Disposable cervical dilator is a medical and surgical instrument commonly used in obstetrics and gynecology. Commonly used gynecological minimally invasive diagnosis and treatment techniques, dilating the cervix is ​​very important for the smooth operation of hysteroscopy. Cervical dilators traditionally used clinically are dilators of different diameters made of metal or hard plastic, which dilate the cervix by physical rigid expansion. This method often results in longer operation time and greater pain for patients. And it is easy to cause adverse reactions such as uterine damage, embryo damage and bleeding. [0003] At present, in order to realize the slow expansion of the cervix, reduce the pain of patients, reduce the difficulty of surgery and the oc...
