Wherein, described button is two, and this two button is relatively arranged on the both sides of described tube core cover.
Wherein, described button is the spring button that is provided with back-moving spring.
Wherein, described gear is engaged in described movable tube core by the big sawtooth of being located at week in it.
Wherein, the periphery of described gear is provided with and is used for anti-skidding little sawtooth.
Wherein, the rear end of described movable tube core is provided with solid piston shape structure bolt, and the afterbody of this solid piston shape structure bolt is provided with handle.
Wherein, described handle is provided with anti-skidding shallow grooves.
In sum, this utility model provides a kind of pinpoint accuracy, easily flushing, has saved flushing liquor and easy to operate embryo transplanter for the test-tube baby operation.
For further setting forth this utility model is technological means and the effect that the predetermined purpose of realization is taked, see also following about detailed description of the present utility model and accompanying drawing, believe the purpose of this utility model, feature and characteristics, should obtain thus going deep into and concrete understanding, yet accompanying drawing only provides reference and explanation usefulness, is not to be used for this utility model is limited.
Description of drawings
Below in conjunction with accompanying drawing,, will make the technical solution of the utility model and other beneficial effects apparent by the specific embodiment of the present utility model is described in detail.
In the accompanying drawing,
Fig. 1 is the cross-sectional view of this utility model embryo transplanter one preferred embodiment.
The specific embodiment
As shown in Figure 1, it is the cross-sectional view of this utility model embryo transplanter one preferred embodiment, and this embryo transplanter comprises tube core cover 1, fixedly tube core 2, movable tube core 3, solid metal 4, button 5, rule 6, gear 7; It is bore end 8 that this tube core overlaps 1 front end, this fixedly tube core 2 fixed covers be loaded in the front end of tube core cover 1, this fixedly the central authorities of tube core 2 be provided with elongated pipeline 20 and be communicated with described bore end 8, this activity tube core 3 is set in tube core and overlaps in 1 the rear end; These solid metal 4 one ends are fixed in the front end of this activity tube core 3, and its other end inserts in the described pipeline 20 and can slide along pipeline 20; Fixedly be reserved with an intersegmental crack between tube core 2 and the movable tube core 3, described button 5 passes the wall of tube core cover 1 and is close to movable tube core 3, and its underpart was positioned at tube core cover 1 and backstop activity tube core 3 when button 5 was pressed; Described gear 7 is articulated in tube core and overlaps 1 rear end and be meshed with the set sawtooth in movable tube core 3 surfaces, and the part of this gear 7 exposes to this tube core cover 1, stirs this gear 7 and can slide along tube core cover 1 by drive activity tube core 3; Described rule 6 is positioned on the wall that tube core overlaps 1 rear end and is close to described button 5.
In this preferred embodiment, about 0.44 millimeter of bore end 8 overall diameters of tube core cover 1, big or small syringe-like; It is the high rule of microlitre 6 that unit is arranged on the tube wall that button 5 and gear are 7, and this unit value degree of accuracy height is convenient to user control.What link to each other with rule 6 is gear 7, the big sawtooth 71 in week and the little sawtooth 72 of periphery in gear 7 comprises, and little sawtooth 72 plays anti-skidding effect, and big sawtooth 71 can interlock be fixed movable tube core 3; Moment when the design of the dual sawtooth of employing inner periphery and the outer periphery can strengthen handsetting gear 7, thus be convenient to operation.Button 5 is two spring buttons that are provided with back-moving spring, and is relatively arranged on the both sides of tube core cover 1.Can backstop fix movable tube core 3 after pressing the button 5; Press the button 5 by rising during operation, it can be in tube chamber, movable tube core 3 pushed ahead contact the back with surface 21 and connect grafts, move movable tube core 3 backward then and utilize vacuum effect to draw culture fluid, until the front end of movable tube core 3 position above button 5 at bore end 8.Before drawing the embryo, earlier button 5 is pressed, more movable tube core 3 is passed until touching button 5 to button 5, operate according to routine absorption embryo's program again.Be provided with spring in the button 5, can conveniently regulate.About 0.5 millimeter of solid metal 4 diameters, therefore, rule 6 per 5 millimeters scales are represented 1 microlitre.The rear end of movable tube core 3 is provided with solid piston shape structure bolt 31, and the afterbody of this solid piston shape structure bolt 31 is provided with handle 32, and handle 32 is provided with anti-skidding shallow grooves, is convenient to operation.
Than existing embryo transplanter, embryo transplanter of the present utility model has increased structures such as solid metal 4, button 5, rule 6 and gear 7 newly; Solid metal 4 can be saved flushing liquor, and button 5, rule 6 and gear 7 all are to draw and degree of accuracy when intrauterine is transferred the embryo in order to control, and the embryo transplanter of this structure is the operation migration process better, raising embryo's survival rate.
