Abstract
A kind of double sacculus cervical dilators, containing two sacculus of size, small sacculus is placed in big sacculus, and two sacculus are separately connected different cavities, and the aqueous vapor in cavity enters sacculus by stomata, is further connected with the gas connector that discharges water with the cavity tail portion of big sacculus connection.During operation; doctor often must clamp swelling gasbag with surgical clamp and be sent to cervix opening; easily swelling gasbag is clipped broken; cause top guide that can generate active force and hits uterus or cavity or baby head; and the buffering that the small sacculus in this utility model generates solves this technical problem just, protects uterus inner wall.
Description
Technical field
The present invention relates to medical instruments fields, and in particular to a kind of double sacculus cervical dilators.
Background technique
It is one of vital tissue organ in female reproductive system that uterine neck, which is also known as cervix, and uterine neck is located at uterus lower part, approximate
Cone, long 2.5-3cm, upper end are connected with corpus uteri, and vagina is goed deep into lower end, are mainly made of sheath, also containing smooth
Muscle fibre, blood vessel and elastic fibers, gynaecology and obstetrics operation such as take ring, put ring, induced abortion, examine erasion operation, in operation, by
It is tighter in cervix opening, thus often need to cervical dilator come cervix dilating mouth, to achieve the purpose that operation, such as: prolonged gestation,
Situations such as prolonged pregnancy, hapamnion, gestational diabetes have surpassed the expected date of childbirth fails nature during labor, and pregnant woman will be in face of two choosings
Select: spontaneous labor or cesarean section terminate to give a birth.To the pregnant woman for having spontaneous labor (vaginal delivery) condition, doctor can suggest pregnant
Woman's programed delivery, but uterine neck condition is immature and will increase the difficulty of vaginal delivery, to promote spontaneous labor, reduces pregnant woman and cuts open palace
Yield, so that it may use cervical dilator, made the pregnant woman of a programed delivery more selection and approach.
In the prior art, Chinese patent CN200620083154.2 discloses a kind of cervical dilator, it is by guide rod
It is constituted with swelling gasbag, the expansion tube being arranged in guide rod, swelling gasbag is connected to expansion tube and is fixed on guide rod together
On, swelling gasbag and expansion tube are also communicated with gas tube, will be swollen by way of injecting air or physiological saline into gas tube
Flatulence capsule slowly struts, to make cervix opening spreading.The cervical dilator reduces the pain of patient, but in actual use,
Be sent to cervix opening since doctor often must clamp swelling gasbag with surgical clamp, easily clip broken swelling gasbag, cause top guide by
Fetus is crashed into, needs to be improved.
In Chinese patent CN201220251974.3, use swelling gasbag for bilayer, it is swollen that medial expansion air bag is located at outside
Flatulence is intracapsular, and the gas tube interlinks with medial expansion air bag, this utility model due to the adoption of the above technical scheme, with hand
When art clamp handles swelling gasbag and is passed to cervix opening, medial expansion air bag is not easy to be clipped broken, although the expansion gas of this patent
Capsule has bilayer, but since, there is no spacer, doctor is easy to inside and outside two layers of air bag when using surgical clamp between double-layer air bag
It clips broken together, however it remains some problems.
Utility model content
To solve the above problems, the utility model is as follows using technical solution:
A kind of double sacculus cervical dilators, it is described including tube body, dilatation balloon and the matched locating bar used
Dilatation balloon is made of big sacculus and small sacculus, and small sacculus is placed in big balloon interior, and the tube body is hollow pipe, tubular body
It is provided with cavity one, cavity two and cavity, tube body head is provided with closing seam and is placed in the intracapsular top guide of bead, the pipe
Have the stomata one and stomata two for penetrating through big sacculus and cavity one and the small sacculus of perforation and cavity two on body, cavity one with
Aqueous vapor in cavity two can enter big sacculus and small sacculus, the tail portion of the cavity one by stomata one and stomata two respectively
It connects and discharges water gas connector and switch is installed.
The tail end of the cavity one and cavity two is separately installed with check valve one and check valve two, the check valve one
It is monodirectional locking air valve with check valve two.
Graduation mark is carved on the cavity.
The small sacculus and big sacculus are the ellipticity resilient bladder that sealing is socketed on tube body.
Effective expansion capacity of the small sacculus is 0-250ml, and it is 0-1000ml that the big sacculus, which effectively expands capacity,.
The utility model has the advantages that the big sacculus and small sacculus of the utility model pass in and out air water by two different cavities respectively, greatly,
It is isolated among small sacculus by air water, in gynaecology and obstetrics operation operation, is incited somebody to action since doctor must often clamp swelling gasbag with surgical clamp
It is sent into cervix opening, easily clips broken dilatation balloon, and top guide is easy to generate the head that impact force hits baby, and the utility model
In the case that in outside, big sacculus is destroyed, small sacculus can form buffering, avoid impact force caused by top guide.
