Description
Technical field
The present invention relates to a kind of medical instrument, especially a kind of fetus interventional operation equipment.
Background technique
With the development of modern medicine, some fetal congenital diseases can carry out operative treatment in fetal period, thus
Birth defects are repaired during development of fetus, reduce birth defect and birth defect bring Newborns
It is dead.But carry out fetus intervention operation when, have huge risk, the main source of risk first is that due in hand
During art, need to pierce through surgical instrument the bag of waters, and the pierced bag of waters is likely to result in amniotic fluid outflow, causes fetus
There are the adverse effects such as anoxic, deformity in growth course, while being easily broken after bag of waters puncture causes fetus premature labor even dead
It dies.Although operation can treat fetal congenital disease, operation bring risk is also very important.
Summary of the invention
Goal of the invention of the invention is：In view of the above problems, one kind is provided when carrying out fetus intervention operation,
It is injected between fetal membrane and uterus and seals medical glue, it is pre-sealed to be pierced place's progress to the bag of waters, then carries out penetrating fetal membrane
Intervention operation reduces the fetus interventional operation equipment of bring operation risk after the bag of waters is pierced.
The technical solution adopted by the present invention is as follows：
A kind of fetus interventional operation equipment of the invention, including hollow puncture pipe, the puncture pipe is embedded to be cased with propulsion
Device, the propeller middle part, which is equipped with above sap cavity described in sap cavity, is equipped with push rod, and the propeller front end is connected with two tablettings,
The two tablettings mirror symmetry setting, two tabletting can be rotated by midpoint of tie point.
By adopting the above-described technical solution, two tablettings are unfolded, after piercing through pipe and puncturing uterine wall in fetal membrane and uterus
Between prop up a fritter gap, by sap cavity medical glue injection gap in, to pierced place carry out it is pre-sealed after, then into
Row penetrates the intervention operation of fetal membrane, to reduce bring risk after the bag of waters is pierced.It can be uniform right by two tablettings
Fetal membrane presses, and the tip for piercing through pipe is avoided accidentally to puncture fetal membrane in the operating process for propping up gap.
A kind of fetus interventional operation equipment of the invention, the tabletting middle part is hollow, passes through flexible hair in the middle part of the tabletting
Tubule is connected to sap cavity, and the tabletting medial surface and sap cavity bottom surface are provided with several water seepage holes, the tabletting medial surface and sap cavity bottom
Face is covered with water-permeable membrane, and the water-permeable membrane is water-tight in its natural state, and the water-permeable membrane seeps water under pressure state.
By adopting the above-described technical solution, when advancing downwardly push rod, pressure is generated after gap is propped up in two tablettings,
Medical glue in sap cavity is released into filling chink.
A kind of fetus interventional operation equipment of the invention, the length for piercing through pipe are 6cm, diameter 0.27cm；It is described
The length of propeller is 10cm, diameter 0.13cm；The height of the sap cavity is 1.4cm；The length of the push rod is 11cm；Institute
The length for stating tabletting is 0.12cm, with a thickness of 0.4mm；The water-permeable membrane with a thickness of 490nm；The diameter of the water seepage hole is
0.7μm。
By adopting the above-described technical solution, above-mentioned having a size of optimum size, wound caused by piercing through to the bag of waters is minimum.
A kind of fetus interventional operation equipment of the invention, the puncture bottom of the tube have inclined-plane, the inclined-plane and vertical side
To angle be 30 °.
By adopting the above-described technical solution, the angle can convenient for puncturing, caused by wound it is smaller, puncturing the bag of waters
When, it avoids amniotic fluid excessive from wound two sides, influences the performance of medical glue.
A kind of fetus interventional operation equipment of the invention, the puncture pipe top inner wall is equipped with several protrusions, described convex
It rises and is made of flexible silica gel, the radius of the protrusion is 0.07cm.
By adopting the above-described technical solution, protrusion and propeller between have larger frictional force, avoid propeller due to
Larger displacement variation occurs for the effect of gravity, guarantees that propeller only can be just subjected to displacement in artificial push, avoids as operation
Risk is brought,
A kind of fetus interventional operation equipment of the invention, the tabletting bottom are in arc-shaped, and the tabletting medial surface has
Inclined-plane, the inclined-plane with 20 ° of vertical direction angle.
By adopting the above-described technical solution, tabletting, during pushing, arc surface, which can be avoided, makes the bag of waters
At accidental destruction, and the angle on inclined-plane can take advantage of a situation convenient for tabletting and be unfolded to both sides.
A kind of fetus interventional operation equipment of the invention, the diameter of the flexible capillaries are 0.07mm, the flexibility hair
Tubule is by 27 parts of polyacrylonitrile of mass parts, 7 parts of polybutadiene, 14 parts of polycarbonate, 3 parts of quartzs, 5 parts of nano phase ag_2 os and 29
Part circular acrylic resin composition.
By adopting the above-described technical solution, the flexibility of flexible capillaries is preferable, at the same be able to bear it is biggish hydraulic,
Tube wall can be avoided to rupture when liquid is flowed into tabletting.
