Description

A kind of capillary glass pin operation instrument

Technical field

The utility model belongs to Bioexperiment apparatus field, and in particular to a kind of capillary glass pin store tools.

Background technology

The embryology such as fertilization-embryo transfer, transgenosis, nuclear transfer and Experiment of Zoology room are, it is necessary to gamete in vitro（Essence Son and egg mother cell）And embryo carries out various manipulation in vitro.These manipulation in vitro are required for the capillary glass by different inner diameters Glass pin is completed.For example, about 200-250 microns of the glass needle internal diameter shifted for mankind's blastaea, for human oocytes And about 180-200 microns of the glass needle internal diameter of embryo transfer, it is big to the glass needle internal diameter of human oocytes progress degranulation About 120-150 microns.The capillary glass pin of these different inner diameters is exactly topmost gamete and the manipulation in vitro instrument of embryo.

These capillary glass pins need to use specific instrument to be operated, and most common operation instrument is that glue head and mouth are inhaled Pipe.After capillary glass pin is connected with mouth suction pipe and glue head, by changing the pressure inside glass needle, it becomes possible to by gamete or embryo Tire is sucked or discharge glass needle, so as to complete the transfer and operation of sample.

But, there is certain defect during use in these operation instruments.Because glue head bore is larger, it is necessary to Can be with thinner capillary glass pin using special sealing ring（Rear end external diameter is about 0.5mm）Connection.Further, since capillary Glass needle limited length（About 60-70mm）, desired capillary glass pin of being fixed with finger is relatively difficult in operating process, while easily Pollute the leading portion of capillary glass pin.Therefore, the relatively more suitable working length of glue head is longer, the thicker pasteur pipet of external diameter, without It is suitable to operate not only short but also thin capillary glass pin.

Mouth suction pipe is usually one section homemade plastics or rubber hose, and one end is connected with capillary glass pin, and the other end can To be contained in operator mouthful, operator controls capillary glass pin by changing intraoral air pressure.But mouth suction pipe has following 3 Individual defect：First, the use of mouth suction pipe needs higher skill, it is necessary to the close fit in hand and oral cavity, it is necessary to pass through repeatedly Exercise could be grasped skillfully；Secondly, using during mouth suction pipe, for the not intraoral air pressure of interference effect, operator Mute, coughing and sneeze, or even swallow saliva is also very careful.And, it is necessary to operator during certain operations Checked and linked up with support staff, it is now then inconvenient；Finally, mouth suction pipe is usually Reusability, in embryology And Experiment of Zoology room has some biological specimens, such as blood, liquor folliculi, seminal fluid and animal sample, it may carry Pathogenic microorganism.These cause pathogeny imcrobe infections operator's risk will likely be dramatically increased using mouth suction pipe.Therefore, some countries Human in vitro Fertilization laboratory, do not allow operator to be operated using mouth suction pipe.

At present, there is no the capillary glass pin operation instrument of standardization, how it is simple and safe operate effectively capillary glass pin, It is many embryology laboratories, the problem of especially Human in vitro Fertilization laboratory is not yet solved very well." a workman wants to do his work well, must First its device of profit ", makes a kind of simple and safe effective capillary glass pin operation instrument, it will significantly improve gamete and the body of embryo Outer operating efficiency, and farthest the risk of hospital-acquired infection occurs for reduction operator.

The content of the invention

The utility model is intended to overcome the deficiencies in the prior art that there is provided a kind of capillary glass pin operation instrument.

In order to achieve the above object, the technical scheme of the utility model offer is：

The capillary glass pin operation instrument includes the hollow tubular action bars of one end open and located at action bars openend Air bag；The operation bar side wall of the air bag present position is provided with extruded hole；The one end of the air bag towards action bars openend Provided with pin hole, the pinhole diameter ＜ capillary glass pin external diameter.

Wherein, the action bars is made up of metal or bio-safety level plastics, and surface is handled by frosted.

With reference to design principle, the utility model is described in further detail：

The capillary glass pin operation instrument, including action bars and air bag.The action bars is the hollow cylindrical of tubulose, It is easy to operator to hold, action bars one end open, for installing capillary glass pin；The air bag is located in action bars to be opened close to it At mouthful, air bag is having a pin hole close to the position of action bars opening, for fixing capillary glass pin；The action bars of air bag side There is extruded hole on the wall of side, the pressure in air bag is controlled for operator.During use, operator is by the afterbody of capillary glass pin In the pin hole for inserting air bag, action bars is then held with the posture for holding pen, i.e., behaviour is held with thumb, forefinger and middle finger front portion Make front portion of the bar at opening, wherein thumb or forefinger is covered in the top of extruded hole.Now, 3 can be passed through in operation Individual finger, simply and easily moves capillary glass pin and while controls the pressure in pin.

Wherein, the action bars is by metal（Fine aluminium, aluminium alloy or stainless steel）Or bio-safety level plastics（It is polypropylene, poly- Styrene or makrolon）It is made, surface carries out frosted processing.

Wherein, the air bag is made up of elastomeric material, such as silica gel or rubber, and pinhole diameter is less than outside capillary glass pin Footpath, air bag is fixed on inside action bars by the tension force of itself.

The operation instrument size can according to be customized using the type of capillary glass pin, conventional capillary glass pin Exemplified by（Total length 60mm, external diameter 0.5mm, internal diameter 0.3mm）The long 100-150mm of action bars, external diameter is 6-8mm, and wall thickness is 1-2mm, internal diameter is 4-6mm；The a length of 10-15mm of air bag, external diameter is 4-6mm, and wall thickness is 2-3mm, and pinhole diameter is 0.4mm；Extruding hole width is 3-4mm, and degree is 6-8mm.All edges using polishing Passivation Treatment, prevent incised wound from grasping Author's skin.

In use, operator only needs to holding operation bar to the capillary glass pin operation instrument, without touching capillary Glass needle, it is to avoid the possibility of secondary pollution；Operator meets most of operations to hold the gesture operation capillary glass pin of pen The custom of person, operating process simple and stable, is easily mastered；The probability for directly contacting operator with biological specimen in operating process Minimize, it is to avoid the risk of cause pathogeny imcrobe infection.

In a word, capillary glass pin operation instrument of the present utility model, being capable of simple and safe reliable operation knitting wool glass needle Manipulation in vitro is carried out to gamete and embryo.The defect of traditional operation instrument is overcome, gamete and the external behaviour of embryo is significantly improved Make efficiency, and farthest reduction secondary pollution and hospital-acquired infection odds.
