Abstract
The invention relates to a fish gonadal tissue taking device fast to manufacture. The fish gonadal tissue taking device fast to manufacture comprises a bone marrow biopsy puncture needle, the bone marrow biopsy puncture needle is provided with a needle core and a casing pipe, the needle core is provided with a handle and sleeved with the casing pipe, the needle core and the casing pipe are respectively and correspondingly provided with an inclined incision deepening gradually from rear to front, each incision is stopped at the position 0.5cm away from the needle tip of the front end of the needle core, and the depth of the incisions is the radius of the needle core/ the pipe section of the casing pipe. The fish gonadal tissue taking device is easy and fast to manufacture, can penetrate into a fish from the exterior of the fish to take out the gonadal tissue, and can be widely used for fish sex identification and artificial reproduction.
Description
Technical field
The fish gonadal tissue sampling device that the present invention relates to aquatic products experiment and production field, refers to a kind of making fish gonadal tissue sampling device efficiently especially.
Background technology
Realize the large-scale cultivation of a kind of fish, important approach carries out artificial propagation exactly, and the development condition of understanding in time fish sexual gland is the key of artificial propagation success or not.Most of fish cannot be distinguished male and female from profile at anestrous season, and this has just further increased the difficulty of timely grasp fish gonad development situation.Safe for energy, to check fast fish gonad development situation, will be used some small tools to check conventionally, and modal is exactly to get egg apparatus.
More existing for checking that the egg apparatus of getting of fish mostly is self-control, material differs, and the efficiency of collection is lower, and can not guarantee the safety of fish.Also there are in the market the special-purpose fish of sale to get egg apparatus, all adopt the whole processing of stainless steel material, can only be by factory by special equipment processing and fabricating, other people cannot self manufacture.The general unit that cultivates can only buy on market, not only price is higher, increase the operating cost of cultivation unit, and specification, model aspect also cannot meet the requirement of cultivation unit completely, therefore the general unit that cultivates can not rely on the product on market to meet user demand completely, need the quick and effective fish sexual gland harvester of a kind of makings, for solve carry out that fish sex is identified and gonadal tissue live body is taked during gonad development status checkout fast with efficiently.
Summary of the invention
For the problems referred to above, main purpose of the present invention is to provide a kind of making fish gonadal tissue sampling device efficiently, and what while carrying out fish sex evaluation and gonad development status checkout to realize, gonadal tissue live body was taked is quick and efficient.
The present invention solves the technical scheme that its technical problem takes: a kind of fish gonadal tissue sampling device, it is characterized in that comprising: a myeloid biopsy needle, described myeloid biopsy needle has a nook closing member with handle, an and sleeve pipe that is set in described nook closing member outside, correspondingly respectively on described nook closing member and sleeve pipe be provided with one by dark angular cutouts gradually before backward, described otch ends in apart from described nook closing member front end needle point 0.5 centimeters, and the degree of depth is the radius of described nook closing member/described sleeve pipe pipeline section.
In the technical scheme of the invention described above, the gradient of described otch is 30 degree.
The length of described otch is apart from front end needle point 0.5 centimeters to 2 centimeters.
Described sleeve pipe and described nook closing member are that stainless steel is made, and described handle is that plastic material is made,
Described handle and described nook closing member are structure as a whole, and the front end of described nook closing member is prismatic needle point.
Adopt technique scheme, material source of the present invention is convenient, with low cost, processing is without specific equipment, and process easy, quick, operating personnel can effectively be taked fish gonadal tissue and can be avoided fish injured by shirtsleeve operation, therefore can be widely used in fish sex and differentiate and artificial propagation
Accompanying drawing explanation
Fig. 1 is combining structure schematic diagram of the present invention;
Fig. 2 is the schematic diagram of nook closing member of the present invention;
Fig. 3 is the schematic diagram of sleeve pipe of the present invention.
Embodiment
In order to describe structure of the present invention, Characteristic in detail, the following preferred embodiment of existing act also coordinates accompanying drawing to be described as follows.
A kind of fish gonadal tissue sampling device provided by the present invention, it adopts commercially available myeloid biopsy needle to process.As shown in Figure 1 to Figure 3, myeloid biopsy needle comprises that sleeve pipe 2 and nook closing member 1 are stainless steel with the nook closing member 1 of handle 3 and sleeve pipe 2 two parts of being set in nook closing member 1 outside, and handle 3 is plastic material, with nook closing member 1 being integrated property structure.
The front end of nook closing member 1 is prismatic needle point, core body pipeline section is provided with one by dark angular cutouts 4 gradually before backward, the length of otch 4 is apart from front end prismatic needle point 0.5 centimeters to 2 centimeters, apart from the degree of depth of front end prismatic needle point 0.5 centimeters, is the radius of nook closing member 1 core body pipeline section, and gradient is 30 degree.On sleeve pipe 2, be provided with the otch corresponding with the otch 4 of nook closing member 14 ＇, the degree of depth of otch 4 ＇ front ends is the radius of sleeve pipe 2, and gradient is similarly 30 degree.
The present invention can select according to the size of the size of required inspection fish body and fish-egg the size of used myeloid biopsy needle.Because the myeloid biopsy needle model on market is abundant, and cheap, be easy to buy, therefore greatly open material source of the present invention, has reduced material cost, simultaneously also greatly improved use flexibility of the present invention, and the handling safety can guarantee to check fish time.
Processing method of the present invention is, utilize hacksaw apart from front end needle point 0.5 centimeters, cutting respectively half of nook closing member 1 and sleeve pipe 2, apart from front end needle point 2 centimeters, with 30 degree angles, cutting sth. askew forward, join and just form otch 4 with anterior otch, with Rhizoma Sparganii file, polish smooth and just completed processing of the present invention again, only needing 5-10 minute just can be by the fish gonadal tissue sampling device of common marrow puncture needle processing cost patent.In process, keep incision site and shape on nook closing member 1 consistent with incision site and the shape of sleeve pipe 2.Therefore, processing of the present invention, without specific equipment, is processed easy, quick.
During use, sleeve pipe 2 is enclosed within on nook closing member 1, the handle 3 that hand grips sampling device thrusts at oblique 30 degree of fish body belly (sexual gland top), thrust after sexual gland 2-3 centimetre, by nook closing member 1 together with the sleeve pipe 22 centimetres of left and right of dropping back, otch by sleeve pipe 2 front ends can scrape off gonadal tissue in the otch of falling into nook closing member 1, then sampling device is taken out in fish body, finally nook closing member 1 is taken out from outer sleeve 2, the gonadal tissue that is attached to its otch 4 places can be taken out for differentiating sex or observing gonad development situation.
It should be noted that, the gradient of otch 4 of the present invention is not that strict demand is 30 degree, even if there is deviation not affect use of the present invention yet.
Finally, what must again illustrate is, the content that the present invention disclosed is in the aforementioned embodiment only for illustrating, and those skilled in the art can make various changes or modification to the present invention, and these equivalent form of values fall within the application's appended claims limited range equally.
