Description
Technical field
This utility model relates to a kind of medical auxiliary apparatus, is specifically related to a kind of Cervical cerclage assistor.
Background technology
Incompetence,cervical is the one of the main reasons that cervix uteri Silent Neuritis expansion mid trimester of pregnancy causes repeatedly late abortion, premature labor.Therapeutic Method is to reinforce lax cervix uteri by cervical cerclage, extends pregnant time, improves fetus survival rate.
There is risk in cervical cerclage, except infecting, also has a material risk may cause rupture of membranes exactly, especially at palace mouth, has been expanded to when quite large.Document " utilizes air bag to return to receive the fetal membrane of bulging palace mouth in order to row emergency case cervical cerclage " (< < foreign medical science obstetrics and gynecology fascicle > >, the 29th the 2nd phase of volume in 2002) a kind of apparatus with air bag is disclosed, this apparatus is 1 plastic catheter, air bag is equipped with on top, end is installed with the equipment that can regulate and control inflation and aerofluxus, there is connector its side, there is union piece ball one end of inflation, during use, people's connector is inserted in this ball one end, return and receive fetal membrane and carry out cervical cerclage.But still there is following shortcoming:
1, the suppleness of air bag is bad, can not initiatively deacclimatize the variation of fetus water pocket, and fetus water pocket still has the danger of breaking;
2, can accurately fixed placement position, easily damage birth canal;
3, under air bag without load-carrying construction, fetus water pocket is subject to one direction when extruding, may cause and break because pressure is excessive.
Utility model content
In order to solve the problems of the technologies described above, this utility model provides a kind of Cervical cerclage assistor, before carrying out Cervical cerclage, amniotic sac is upwards touched, and gives the enough spaces of operator and sews up, and amniotic sac is played a good protection.
For achieving the above object, this utility model adopts following technical scheme:
Cervical cerclage assistor, is characterized in that: comprise cavity, hollow ram, Y-pipe, water pocket chamber; Described Y-pipe, a drainage tube for connection water pocket chamber, one is water injection pipe, one is outlet pipe, and outlet pipe is sealed tube, and the front end of described hollow ram is provided with water pocket holder, described drainage tube is through hollow ram, and water pocket chamber is positioned at water pocket holder, and described hollow ram is through cavity; Two or two the above wings of described water pocket holder for drawing in.
While not using, the water pocket restitope of push rod is in cavity; Before operation, cavity front end is softly positioned over to intravaginal, proficiency fixed cavity, another have gentle hands push rod, exposes water pocket holder, then water filling in the water injection pipe outside vaginal orifice, make water pocket chamber in water pocket holder full, continue to touch push rod, allow on full artificial water pocket and push away fetus water pocket, expose cervix uteri, carry out cervical cerclage; During end, by empty needle pipe suction outlet pipe, extract the water injecting in artificial water pocket out, draw back push rod, water pocket holder can be retracted back in cavity, slowly from intravaginal, takes out cavity, uses and finishes.
When this utility model utilizes water pocket and fetus water pocket interaction force, pressurized is balanced, is difficult for causing fetus water pocket to break.
Described water pocket chamber is half elliptic, ellipse be on while pushing away fetus water pocket, make fetus water pocket balanced with the contact surface of artificial water pocket, pressurized is also balanced, reduces the risk of breaking.
Preferably, described water pocket holder is half elliptic, adapts with the shape in water pocket chamber.With semielliptical water pocket holder, be for fixing artificial water pocket, and keep its ovalize.
Preferably, be provided with contractile outthrust on described push rod, be provided with aperture on cavity, described outthrust is corresponding with aperture.When push rod is upwards shifted correct position onto, outthrust just in time sticks into corresponding aperture, so that fixing.
The material in described water pocket chamber is elastic material.
The beneficial effects of the utility model are:
1, with pushing away fetus water pocket on water pocket, the suppleness of water pocket is good compared with air bag, can initiatively deacclimatize the variation of fetus water pocket, thereby shares the pressure of fetus water pocket, reduces the incidence rate that fetus water pocket breaks.
2, Cervical cerclage assistor of the present utility model is provided with cavity, hollow ram, the built-in drainage tube of hollow ram, upper accepting water capsule, because soft birth canal is a state in closing, vaginal wall and cervix uteri matter are soft, and the design of cavity is fixed placement position very accurately, and stationarity is strong.
3, make for having elastic material in the water pocket chamber of this patent, and its water injection rate, without fixing, can carry out personalization adjustment according to fetus water pocket and cervix uteri hypomere diameter; The water pocket holder designing under water pocket can make water pocket keep oval, by the more effective fetus water pocket of holding, has increased compression area, while not allowing fetus water pocket be subject to one direction extruding, because excessive the causing of side's pressure broken.
