Description
Technical field
The present invention relates to technical field of cell biology, more particularly to a kind of electronic ovarian follicle revulseur.
Background technology
Ovary is the Main Reproductive Organs of female mammal, and ovarian follicle is the main constituents in ovary.Primordial follicle
It is made up of the individual layer scales granular cell of egg mother cell and surrounding, granular cell participates in regulation and control ovarian follicle from growing maturation
The whole process of ovulation, they will undergo primary, secondary follicle and antral follicles stage successively, be ovulated subsequently into graaffian follicle
Phase.From primordial follicle to Graafian follicle or atretic follicle is a complicated and accurate process, the granular cell of differentiation with
Egg mother cell, which is formed, closely to be combined and provides the exchange of information substance, while granular cell can secrete progesterone, estrogen etc.
Hormone and expression specificity acceptor（FSHR）, for example ovulated with this to coordinate the ripe and subsequent activity of Oocyte Development,
Promote fertilization and early embryonic development etc..Granular cell forms entirety functionally with egg mother cell, when granular cell withers
The locking of ovarian follicle will be caused by dying, ovarian follicle once locking can not normal development, ultimately result in female reproduction function associated disorders
With disease.
Primary gonad granulocyte in-vitro culture model is established, is easy to carry out granular cell growth under in vitro conditions, is increased
Grow, differentiation and the research of apoptosis, provided to study the researchs such as female Ovarian Physiological Function, ovary relevant disease and Reproductive toxicology
Good means.The gene of mouse is highly similar to the mankind, and its all kinds of biochemical reactions and people are basically identical, and have and be easy to
Feeding cost is low to wait many merits, therefore is the optimal selection of experimental animal.First, the ovarian granulosa for obtaining a large amount of high quality is thin
Born of the same parents are the important foundations of this aspect research.Mouse granulosa cells separation is mostly shown using experimenter stereoscopic in document at present
Stainless steel punctures ovarian follicle is used under micro mirror, granular cell is discharged into the method in culture medium [1-4].This method is turned out
The primary granular cell purity come is high, and growth and proliferation of cell ability is strong.But there is also weak point, first experimenter to hold
Stainless pin scalp acupuncture pierces ovarian follicle, and efficiency very lowly takes time and effort, and difficult to realize be needled into each ovarian follicle and make granular cell
Thoroughly release, this will largely reduce the collecting amount of granular cell.And if experimenter is in order to collect more granular cells
And abundant acupuncture ovarian follicle, it can generally take again long, granular cell as being transferred in the environment of suitable growth not in time, the death rate
It can increase.Meanwhile the operating time is long, cell is easier contaminated.The result of questionnaire also reflects these problems, mostly
The experimenter that number does the primary granulosa cell culture of ovary has this puzzlement --- and experiment is required for expending great effort pin every time
Many mouse ovarians are pierced, enough primary granular cell quantity could be obtained, this enthusiasm for greatly reducing researcher also hinders
The progress of correlative study is hindered.
The content of the invention
Wasted time and energy the low present situation of efficiency to solve the existing primary granular cell extracting method of ovary, the invention provides
A kind of electronic ovarian follicle revulseur.
In order to realize the purpose of the present invention, the technical solution adopted by the present invention is：
A kind of electronic ovarian follicle revulseur, including fuselage support, the inside of the fuselage support are provided with puncture channel, and described puncture is led to
Matched guide rod is provided with road, one end of the guide rod is past via puncture channel described in electric drive unit drives edge
Multiple motion, the other end stretch out the puncture channel and are connected with asepsis injector syringe needle.
The electric drive unit includes motor and the toggle being driven by motor, the crank connecting link machine
Structure includes driving gear, the reduction gearing engaged with driving gear, and the driving gear forms train of reduction gears with reduction gearing,
The power transmission shaft of bias is provided with the card of the reduction gearing, the transmission outer shaft sleeve is equipped with axle sleeve, and the axle sleeve passes through company
Bar is connected with guide rod, the wheel axis connection of the motor and driving gear, and battery, the electricity are additionally provided with beside the motor
Machine switch is arranged on fuselage support side.
Battery is provided with beside the motor.
The asepsis injector syringe needle and guide rod connected mode are clamping or grafting.
The asepsis injector syringe needle is dismountable disposable sterilized injector syringe needle.
The beneficial effects of the present invention are：
Whole device substantially reduces by the way that simply cleverly design improves the deficiency that existing ovarian follicle needle point method obtains granular cell
The work load of experimenter, has been obviously improved conventional efficient.The mock-up produced also achieves well in an experiment
Effect, compared to former manual needle point method, the more better quality of granular cell obtained using electronic ovarian follicle revulseur,
Required time is shorter, efficient quick, obtains the consistent favorable comment of multidigit user.
Brief description of the drawings
The present invention is described further with case study on implementation below in conjunction with the accompanying drawings.
Fig. 1 is the top view of the present invention；
Fig. 2 is the front view of the present invention.
Wherein, 1 asepsis injector syringe needle, 2 guide rods, 3 switches, 4 puncture channels, 5. fuselage supports, 6. connecting rods, 601 axles
Set, 7 reduction gearing, 701 power transmission shafts, 8 batteries, 9 motors, 901 driving gears.
Embodiment
The present invention is further described with reference to the accompanying drawings and examples：
Referring to Fig. 1-2.
The invention discloses a kind of electronic ovarian follicle revulseur, including fuselage support 5, the inside of the fuselage support 5 is provided with
Puncture channel 4, the puncture channel 4 is interior to be provided with matched guide rod 2, and one end of the guide rod 2 is via motorized motions
