Description
Technical field
The present invention relates to human fertility tries hard to keep deposits technical field, more particularly to a kind of human ovarian organizes frozen under liquid nitrogen
Device.
Background technology
Heavy dose of systemic chemotherapy or radiotherapy in cancer healing process can have a strong impact on the fertility of young woman, there is statistics
The young patient that malignant tumor is suffered from display receives after Radiotherapy chemotherapy 1/3 will be infertile.At present, the side of tumor patient fertility is protected
Method mainly has 3 kinds：Embryo cryopreservation, oocyte freezing and ovary tissue freezing.But embryo cryopreservation is unsuitable for preadolescence or does not have
Have with occasionally without the women of tribute essence；Oocyte freezing then needs the longer induced ovulation cycle, there is delay treatment tumor most
The risk on good opportunity；Ovary tissue freezing is drawn materials not by time restriction, in female fertility because can simultaneously preserve a large amount of follicles
Preservation aspect has wide potential applicability in clinical practice.
At present ovary tissue is frozen there is no unified standard, conventional cryopreservation methods to have sequencing freezing and vitrification at a slow speed cold
Freeze.But sequencing freezing needs the Slow-rate freezing instrument of purchasing expensive, freezing whole process to need 2-4 hours, and operation is relative complex, and vitrification
Freezing, then can make ovary tissue be in glassy state, it is to avoid intracellular ice in the temperature-fall period being exceedingly fast and in the extremely short time
Brilliant formation, with it is quick, efficient, easily and economically the characteristics of and be used widely.
Conventional Vitrification of Ovarian Tissue method has:Frozen tube method, microdroplet Vitrification, solid surface vitrification
Method and metallic sieve method.
Different from embryo and oocyte, ovary tissue has, cortex follicles regions sensitivity many containing cell quantity, species
Fragile the features such as.Therefore, select suitable cryopreservation device most important during glass freezing, cooling is improved as far as possible
Speed, makes ovary tissue reach glassy state, while reduce the stimulation to sensitive cortex follicles regions damaging.Frozen tube method because
In operation first by ovary tissue tubulation seals, liquid nitrogen is subsequently put into again, actual is a kind of mediate contact liquid nitrogen method, its drop
Warm speed is far below contact method, causes Follicles quantity and proliferation activity after recovery to be significantly lower than remaining method.Microdroplet
Vitrification, solid surface vitrification method are direct liquid nitrogen contact method, although be attained by preferable rate of temperature fall, but throwing
To enter be both needed to after liquid nitrogen and under liquid nitrogen ovary tissue is fitted in cryovial with tweezers, because liquid nitrogen has volatility, tubulature operation
Interference is big, and tweezers grips that dynamics is wayward under liquid nitrogen, and physical property extruding damage is easily caused to sensitive cortex follicle area
Wound.Metallic sieve method is that first ovary tissue is placed on metal grill, is loaded into again in stored frozen bag after input liquid nitrogen, though
The directly contact of tweezers and ovary tissue is so avoided, but stored frozen bag resists mechanical stretch ability not as freezing at -196 DEG C
Pipe is deposited, it is easy to crack, and stored frozen bag shape do not fix, and is difficult frozen in order.
The content of the invention
For the deficiencies in the prior art, the present invention provides a kind of effect that can reach very fast cooling, is avoided that again to quick
The stimulation of sense cortex follicles regions is damaged, at the same can ensure that under liquid nitrogen it is easy to operate accurately, store it is safe and reliable, compatible in order,
And the human ovarian of nontoxic pollution-free organizes cryopreservation device under liquid nitrogen.
Technical proposal that the invention solves the above-mentioned problems is：
A kind of human ovarian organizes cryopreservation device under liquid nitrogen, including for deposit human ovarian tissue body, the pipe
One end of body is provided with opening, and opening is furnished with closure, and the closure is detachably connected with the body, closure and body
Enclose closed parking space；
The inner top surface of the closure is provided with the fork for taking human ovarian's tissue for fork and takes device.
Further, the fork takes device including some fine needles be arrangeding in parallel, and the fixing end of fine needle is vertically fixed on close
On the inner face of capping, free end axially the extending into body along body of fine needle.
Further, the fork takes device including 3 fine needles, and 3 fixing ends of 3 fine needles of first place connection constitute one positive three
It is angular, and the center of circle of closure inner face is the center of the equilateral triangle.
Further, the material of the fine needle is argent, and the diameter range of the fine needle is 0.3mm～0.4mm.
Further, the body is hollow cylinder shape, and the outside wall surface at body open is provided with external screw thread, closure
Internal face is provided with the female thread being engaged with the external screw thread.
Further, the material of the body and the closure is the polypropylene for being resistant to -196 DEG C of low temperature.
Further, a diameter of 26mm of the body, a diameter of 27mm of closure.
Further, sealing ring is provided with the closure, the sealing ring is silicon gum gasket ring.
Fine needle of the present invention is used to fix direct plunge into Liquid Nitrogen after ovary tissue so that tissue fritter can be straight with liquid nitrogen
Contact, and fine needle adopts the higher argent of heat conductivity as material, then cause ovary tissue to lower the temperature in liquid nitrogen faster,
Glass freezing effect can preferably be reached；The medullary substance part of ovary tissue is fixed with acupuncture needle, then effectively prevent tweezer under liquid nitrogen
Sub-folder takes and the physical stimulation of the cortical section of follicle enrichment is damaged.
And the design of inventive closure formula then avoids other pollutions of iatrogenic material to ovary tissue in liquid nitrogen container；Carefully
The arrangement of pin is set to equilateral triangle, and fine needle diameter range is set to 0.3mm～0.4mm, then can effectively by ovary tissue
A plane is fixed on, and the diameter of body and closure is respectively set to the 2 of conventional 2ml spermatozoa cryopreservation pipe pipe shafts and lid
Times, the parking space of ovary tissue had both been ensure that, cause the cryopreservation device to be put into conventional freezing storing box with compatibility again and (cut with blade
Go to be connected " cross " plastic support in 4 little square storage element lattice central authorities, that is, make the big pros that capacity is 4 times
Shape storage element lattice).
The hickey part colours of closure and body are set to assertive colours (redness) so that in the feelings for having liquid nitrogen to volatilize
Both identifications that also can be apparent under condition, and accurately carry out screwing operations；Closure and body are adopted and are resistant to -196 DEG C
The polypropylene material of low temperature, and through ethylene oxide sterilization processes, it is to avoid body breach and material caused by ultralow temperature
Toxic action to ovary tissue itself.The present invention is repeatable after sterilized to be utilized, and can be made marks on outer wall of the present invention,
It is easy to long-term preservation.
Beneficial effects of the present invention are mainly manifested in：
1st, fork of the invention takes device and had both avoided under liquid nitrogen with the gripping of tweezers blindness to follicle enrichment in ovary tissue
The physical damnification of cortical section, turn avoid the cross-contamination with other iatrogenic materials in liquid nitrogen container, and fork takes device for solid
Determine the medullary substance part of ovary tissue, simple structure, facilitate handy.
2nd, fine needle adopts the higher argent of heat conductivity as material so that ovary tissue can reach faster under liquid nitrogen
To glass freezing effect.
3rd, device is repeatable after sterilized utilizes, economical environment-protective.
