Description
Technical field
The utility model belongs to suckling mouse cochlea dissecting needle technical field, is related to a kind of multi-functional cochlea dissecting needle.
Background technique
Cochlea dissection is always the basis of inner ear research, more particularly to the research of Spiral Ganglion nerve cell.
Experimenter also needs can completely to come out cochlea anatomical isolation while needing the skilled anatomical structure for understanding cochlea, this
To the more demanding of laboratory technician.Cochlea when dissected is being carried out to the suckling mouse being just born, due to suckling mouse cochlea undeveloped mature, cochlea
Hardenability is inadequate, is dissected according to currently marketed microforceps, and the dissecting forceps of common diameter 0.15mm is in high power
It is still relatively thick under microscope, it is unfavorable for accurate operation, is extremely easy to discerp in the spiral ganglion tissue in spiral case and spiral case, thus
It can not achieve complete materials.And the smallest microdissection tweezer diameter about 0.05mm of diameter and flexibility having in the market are inadequate, power
Degree does not reach requirement, and is easy to happen bending, and expensive.In addition, i.e. using taking-up cochlea also nerve cell is caused
Very macrolesion is unfavorable for testing in next step, very time-consuming and laborious.Simultaneously because the improper wave for also resulting in many experimental mouses of dissection
Take, all brings some unnecessary losses to country and school.Moreover in experimental study, the study of new group member is often related to,
If not good disscting instrument auxiliary exercise, new group member is very difficult to skillfully to grasp anatomy in a short time and (utilizes market
Upper existing dissection equipment, the two sides cochlea that a mature laboratory technician dissects a nascent experimental mouse probably need half an hour.
One newcomer uses to skilled, probably needs one-year age).The waste of many experimental mouses is just caused in this, together
When also delay experiment smoothly carry out.Now disclose a kind of toy brain anatomy work of Patent No. CN201520984997.9
Tool, including hold handle, be respectively equipped with brain anatomy needle at the both ends for holding handle and take brain spoon, brain anatomy needle is hollow tubular knot
Structure, and the syringe needle back side is arc surface, front is scarf；Take brain spoon quadrangle to be passivated, take in the middle part of brain spoon be equipped with wait dissect
The arc-shaped curved surface of toy brain volume matched.A kind of toy brain anatomy tool disclosed by the utility model, it is multiple for one
Conjunction tool is respectively set brain anatomy needle at the both ends for holding handle and takes brain spoon, and a tool possesses multiple functions.The tool knot
Rationally, easy to manufacture, easy to use, principle is simple, the efficiency of toy brain anatomy can be improved, and effectively reduce and take for structure design
Sample pollution.
For shortage currently on the market with targetedly cochlea disscting instrument, cochlea dissecting needle can allow user to experience
Using feel and facilitate user to more good and skillfully dissect process within the shorter time, can also choose out snail
More completely they are separated when shell and chorista.To reach saving experiment materials the time and improve cochlear tissue from
The survival rate of body culture, save country and school research funding, can more preferably carry out experiment, greatly promote experimental study into
Degree.
