Abstract
The utility model relates to a kind of novel Polar body biopsy pipes, belong to reproductive medicine micromanipulation technical field of tools in vitro fertilization.It is made of glass tube rod and glass tube head, glass tube head is to 30 degree of angles of glass tube rod direction bending, and production has a spill annulus on glass tube head, and distance of the spill annulus apart from bending arc is 100 microns, the width of spill annulus is 10 microns, and the depth of spill annulus is 5 microns.The utility model has a spill annulus due to making at 100 microns of bending arc in glass tube head, it avoids and uses when carrying out micromanipulation because suction is excessive or too small, cause cell to be sucked out the problem of can not find or be not inhaled into outside field of microscope range, operator is facilitated to carry out micromanipulation；And after glass tube head is bent to glass tube rod direction, no matter curved too long or too short of glass tube head, spill annulus above glass tube head scoots about after all preventing cell from entering in glass tube rod, reduces the operation difficulty that can not be shifted in operating process because egg mother cell is run.
Description
Technical field
The utility model relates to a kind of novel Polar body biopsy pipes, belong to reproductive medicine micromanipulation tool technique neck in vitro fertilization
Domain.
Background technique
In vitro fertilization is that a kind of sperm is combined a kind of fereilizing style for generating gamete with ovum in vitro in female.At this
In kind extracorporeal fertilization process, the polar body of egg mother cell can be used as material to carry out genetic analysis diagnosis, reaching selection just
In normal embryo transfer to maternal uterine, thus improve pregnancy rate and avoid the fetus implantation with genetic disease, birth.Polar body is living
Inspection pipe is exactly the syringe needle to be used of Polar body biopsy, can draw the polar body in egg mother cell by it to do genetic diagnosis.But it is existing
It is had following defects that in some Polar body biopsy pipe use processes
1, the bad grasp of suction, it is that cell can be sucked out field of microscope range and can not find outside when suction is excessive sometimes,
Sometimes when suction is too small, cell is not inhaled into again, brings great inconvenience to operator.
2, after glass tube head is bent to glass tube rod direction, it may appear that the cell of absorption is easy to go from place to place in glass tube rod
It is dynamic, the phenomenon that bad fixed egg mother cell.
Summary of the invention
The purpose of this utility model is that in view of the above shortcomings of the prior art, providing one kind in glass tube rod and glass
Below the bending arc of tube head appropriate location production have a spill annulus, avoid the cell for being drawn into glass tube head scoot about and
It can not find, thus the very well novel Polar body biopsy pipe by cell injection vessel.
The utility model is to realize above-mentioned purpose by the following technical solutions:
A kind of novel Polar body biopsy pipe, it is made of glass tube rod and glass tube head, it is characterised in that: glass tube rod is circle
Cylindricality, glass tube head are cone made of heating is drawn, and pass through taper made of drawing between glass tube rod and glass tube head
Funnel structure connection；For glass tube head to the direction bending of glass tube rod, the bending angle a of glass tube rod and glass tube head is 30 degree；
The length b of the glass tube head is 550 microns, and the diameter of glass tube rod is 780 microns, glass tube head made of heating is drawn
Path be 15 microns, production has a spill annulus on glass tube head, and distance c of the spill annulus apart from bending arc is 100 microns,
The width of spill annulus is 10 microns, and the depth of spill annulus is 5 microns.
The beneficial effect of the utility model compared with prior art is:
1, the novel Polar body biopsy pipe makes at 100 microns of bending arc in glass tube head has a minimum diameter for 10-
12 microns of spill annulus is avoided using, because suction is excessive or too small, cell is sucked out aobvious when the progress micromanipulation of this product
The problem of microscope fields range can not find outside or cell is not inhaled into, facilitates operator easily to carry out micromanipulation.
2, due on glass tube head production have spill annulus, when glass tube head to glass tube rod direction be bent after, no matter glass
Curved too long or too short of glass tube head, the spill annulus above glass tube head can all prevent the cell drawn from entering in glass tube rod
Portion scoots about, convenient for operation.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of novel Polar body biopsy pipe；
Fig. 2 is after glass tube rod and glass tube head bending and the structural schematic diagram of spill annulus.
In figure: 1, glass tube rod, 2, glass tube head, 3, spill annulus, 4, bending arc.
Specific embodiment
The novel Polar body biopsy pipe is made of glass tube rod 1 and glass tube head 2, and glass tube rod 1 is cylinder, glass tube head
2 be cone made of heating drawing, is connected between glass tube rod 1 and glass tube head 2 by conical hopper structure made of drawing
It connects；For glass tube head 2 to the 1 direction bending of glass tube rod, the bending angle a of glass tube rod 1 and glass tube head 2 is 30 degree；Described
The length b of glass tube head 2 is 550 microns, and the diameter of glass tube rod 1 is 780 microns, and the path of glass tube head 2 is 15 microns, glass
Production has a spill annulus 3 on glass tube head 2, and distance c of the spill annulus 3 apart from bending arc 4 is 100 microns, the width of spill annulus 3
Degree is 10 microns, and the depth of spill annulus 3 is 5 microns.
The novel Polar body biopsy pipe is made by glass material, draws ovum mother carefully for being fertilized in microscopic procedure in vitro
Polar body in born of the same parents does genetic diagnosis.Before use, first to check whether product specification is consistent with demand.In use, by herein
Tail of product pressurization, the polar body in egg mother cell is drawn by negative pressure, then the polar bodies of oocyte of absorption is transferred to culture
In ware, the polar body (special cells left outside egg mother cell) of egg mother cell is used to examine as material to carry out genetic analysis
It is disconnected.The Polar body biopsy pipe should be in the environment of being protected from light, drying, divulge information and 16-26 DEG C of environment temperature, relative humidity are no more than 50%
Storage, when transport, should handle with care, and against pressure, shatter-resistant, rain and snow leaching are splashed.
The above is the preferred embodiment of the utility model, and the example above illustrates the not reality to the utility model
Matter content makes any form of restriction, and person of an ordinary skill in the technical field is after having read this specification according to this reality
It is taken off with novel technical spirit to any simple modification or deformation made by the above specific embodiment, and possibly also with above-mentioned
The technology contents shown are changed or are modified to the equivalent embodiment of equivalent variations, still fall within technical solutions of the utility model
In range, without departing from the spirit and scope of the utility model.
