Description
Technical field
The auxiliary device used in performing the operation the utility model is related to a kind of Cervical cerclage, and in particular to one kind will be for that will protrude
The bag of waters outside uterine neck internal orifice pushes back intrauterine device.
Background technology
Incompetence,cervical be second trimester of pregnancy uterine neck Silent Neuritis expansion the main reason for leading to late abortion repeatedly, premature labor it
One.Therapy is that loose uterine neck is reinforced by cerclage of cervix, extends pregnant time, improves fetus survival rate.
Cerclage of cervix, and find that the length of uterine neck becomes the emergent cerclage of cervix used in short-term in ultrasonic examination
(Urgent Cerclage) etc..As amnion expansion be projected into outside cervical orifice when, the best approach carry out, being will be outstanding
After amnion pushes back intrauterine cavity, the operation method of uterine neck is sutured.
It hangs one's head supine posture as the method that the amnion protruded from outside cervical orifice is pushed back intrauterine cavity
Saline solution input method in (trendelenburg position), bladder utilizes wet sponge pincers (Sponge Forcep) or not
The method etc. that amnion is inserted in intrauterine cavity by Lei Shi catheters (Foley Catheter).
The method of lying on the back of hanging one's head be puerpera to lie low in the state of, to make amnion enter original position, lift foot and push away naturally
Into method, saline solution input method is that the saline solution of specified amount is put into bladder in bladder, and sheep is pushed away by the saline solution
The method of film is the method clamped the sponge got wet with pliers and be inserted into amnion using the method that wet sponge clamps.
Mainly using the method using wet sponge pincers in the existing cerclage of cervix, and the method is sharp because of its structure
And amnion is damaged, it is particularly present and amnion is inserted in after intrauterine cavity when taking out wet sponge, amnion can be again from intrauterine cavity
Distinct issues.
Also, the existing insertion method using not Lei Shi catheters substantially uses when cervical dilatation is small, in sheep
When membrane swelling, since the not Lei Shi catheters are bent and are difficult to be operated with this.
In the prior art, Chinese Patent Application No.:201420437676.2 notification number CN203953773U, title:" one
Kind can be used for the silica gel support in cerclage of cervix ", disclose a kind of device for pushing the bag of waters outside prominent uterine neck.It should
Device is front end made of silica gel with downward projection of supporting part and is fixed on the handle of supporting part lower end and forms
's.The drawbacks of this device, is:1, supporting part is made of silica gel, and harder than amnion is more, and silica gel substantially will not in force process
It deforms as pressure becomes larger, so as to cause the stress much larger than other parts is formed at individual points on amnion surface, holds
Easily puncture the bag of waters;2, supporting part size is fixed, and can not adapt to the different projecting degree of the bag of waters width different with cervical dilation
Degree.Greater risk and difficulty are brought to operation.
Chinese patent, application number:CN201420270793.4, notification number:CN203873843U, entitled " Cervical cerclage
Assistor " discloses another bag of waters pusher.It secures water pocket support and water pocket in push rod front end, but public from it
From the point of view of the picture and word of cloth, the edge of water pocket support is it is possible to form the stress concentration point for puncturing amnion.In addition, water pocket
Shape there is no limit its visible water pocket is elliposoidal from its attached drawing, and this shape makes, push component can not will be outstanding
The bag of waters wraps, and can form the face that stress is concentrated on water pocket top, is easy the compressing bag of waters, is also easy that push component is made to exist
Bag of waters surface slidably reciprocates, and improves the probability of bag of waters breakage.
Chinese patent, application number:CN201310263604.0, title:" amnion insertion apparatus " discloses a kind of top and fills
Gas, bag of waters pusher.In actual use, inflation is once to complete to the device.But if air bag, which crosses conference, to be caused to push away
Difficulty is sent, or excessively stimulates uterine neck, leads to stress reaction, air bag size can not be easily adjusted very much in art.If air bag is too small again
It is easy to puncture the bag of waters.And inflation is supplied by inflator or air pump, the adjustable air demand of unit is very big, can not be to air bag size
It is finely adjusted.Therefore, to reach accurately effect, it is extremely difficult.
Invention content
The purpose of this utility model is to provide a kind of cerclage of cervix bags of waters convenient for accurate adjustment air bag size
Propulsion device.
To achieve the goals above, the utility model include a handle and swelling gasbag, the top end opening of the handle,
