Abstract
The invention discloses a kind of cervix dilators, include screw rod, the inner thread sleeve for rotating and sliding on screw rod is socketed on the screw rod, it is slided between the screw rod and inner thread sleeve equipped with multiple with inner thread sleeve by the enlarged portion of cervical dilatation, the enlarged portion includes first expansion part hinged with screw tip, the first expansion part other end is sequentially hingedly connected with the second expansion part, third expansion part, the third expansion part other end is articulated and connected with inner thread sleeve, being rotated by inner thread sleeve and screw flight makes shrapnel deform upon the expansion for realizing cervix.
Description
[technical field]
The present invention relates to a kind of cervix dilators.
[background technology]
During prior art expansion cervix, quantitatively cervix need to be carried out using the different expander of multiple caliber standards
It gradually expands, such as opens cervix first with the expander that caliber standard is 5mm, recycle the expander of other caliber standards afterwards
Gradually expand cervix, this causes user to need to operate repeatedly, and the time is caused to waste, while replace expander expansion when it is easy
Cause secondary injury.
[invention content]
The invention overcomes the shortcomings of the above-mentioned technology and provides a kind of cervix dilators, pass through inner thread sleeve and spiral shell
The threads turn of bar makes shrapnel deform upon the expansion for realizing cervix.
To achieve the above object, present invention employs following technical proposals：
A kind of cervix dilator, includes screw rod, and the interior spiral shell for rotating and sliding on screw rod is socketed on the screw rod
Line sleeve is slided with inner thread sleeve by the enlarged portion of cervical dilatation between the screw rod and inner thread sleeve equipped with multiple,
The enlarged portion includes first expansion part hinged with screw tip, and the first expansion part other end is sequentially hingedly connected with
Second expansion part, third expansion part, the third expansion part other end are articulated and connected with inner thread sleeve.
The screw rod be equipped be slidably connected and with inner thread sleeve slide and slide sliding sleeve, the third expansion part with
Sliding sleeve connects.
The enlarged portion is equipped with elastic rubber layer.
The enlarged portion is four, and the enlarged portion is uniformly arranged on screw rod surrounding around screw rod.
The screw tip, which is equipped with, is oriented to spherical surface.
The beneficial effects of the invention are as follows：
The present invention by rotating inner thread sleeve, when inner thread sleeve moved on screw rod, so as to push shrapnel that shape occurs
Become, cervical dilatation during arcuation deformation, and the present invention can rotate inner screw sheath according to the cervical dilatation width of actual demand
Cylinder, without operating repeatedly, can expand according to actual demand variable, avoid secondary injury and save the time.
[description of the drawings]
Fig. 1 is structure sectional view of the present invention；
Fig. 2 is use state sectional view of the present invention.
[specific embodiment]
It is described in further detail below in conjunction with the accompanying drawings with embodiments of the present invention：
As depicted in figs. 1 and 2, a kind of cervix dilator includes screw rod 1, is socketed on the screw rod 1 in screw rod 1
Upper rotation and the inner thread sleeve 2 slided, are equipped between the screw rod 1 and inner thread sleeve 2 and multiple are slided with inner thread sleeve 2
The dynamic enlarged portion 3 by cervical dilatation, the enlarged portion 3 includes first expansion part 31 hinged with 1 top of screw rod, described
First expansion part, 31 other end is sequentially hingedly connected with the second expansion part 32, third expansion part 33, and the third expansion part 33 is another
One end is articulated and connected with inner thread sleeve 2.
Wherein, the screw rod 1 is equipped with the sliding sleeve 4 for being slidably connected and sliding and sliding with inner thread sleeve 2, the third
Expansion part 33 is connect with sliding sleeve 4.
Enlarged portion 3 is stretched into cervix in use, holding 1 end of screw rod, is then expanded according to the cervix of actual demand
Zhang Kuandu rotates inner thread sleeve 2, and inner thread sleeve 2 is made to be rotated to screw rod 1 top and is slided, at this time 2 top of inner thread sleeve
Sliding sleeve 4 is pushed to be slided to top, due between sliding sleeve 4 and third expansion part 33, third expansion part 33 and the second expansion part 32
Between, be hingedly connected between the second expansion part 32 and the first expansion part 31, between the first expansion part 31 and screw rod 1 so that
When sliding sleeve 4 drives third expansion part 33 to slide, 33 and first expansion part 31 of third expansion part props up the second expansion part 32, from
And make cervical dilatation, it is safe and efficient.
1 top of screw rod, which is equipped with, is oriented to spherical surface, convenient for enlarged portion 3 is sent into cervix.
The enlarged portion 3 is equipped with elastic rubber layer 5, preferably cervix inner wall is protected to preserve from.
The enlarged portion 3 is four, and the enlarged portion 3 is uniformly arranged on 1 surrounding of screw rod around screw rod 1, preferably by uterus
Neck is expanded around.
