Abstract
The invention discloses a micro brain-tissue sampler which belongs to the technical field of devices for bioscientific experimental researches. The micro brain-tissue sampler comprises a catheter, a needle core, a sampling tube and a rotary cutter, wherein one end of the sampling tube is provided with a serrated blade, and the inner wall of the sampling tube is provided with a thread; after the needle core is inserted into the catheter, the needle core and the catheter are both inserted into the head of an animal, then the catheter is fixed, the needle core is pulled out, and the sampling tube is inserted into the catheter; the sampling tube is lightly pressed and rapidly rotated for a plurality of circles so as to cut apart an envelope; the sampling tube continues to be lightly pressed and rotated, so that the sampling tube moves downwards, and after the sampling tube reaches a target position of the head according to the positioning depth of a limit head, the sampling tube is rotated again, so that a target brain-tissue is pushed into the sampling tube by the thread in the sampling tube; the rotary cutter is inserted into the sampling tube from an opening of the limit head of the sampling tube, and through rotating the rotary cutter, the connection between the tissue in the internal thread and downward tissues is cut off; and the catheter, the sampling tube and the rotary cutter are taken out together, and then the rotary cutter is taken out. The micro brain-tissue sampler disclosed by the invention is easy to operate, small in tissue damage, high in precision, simple instructure and low in manufacturing cost, and can be applied to the establishment of intravital nucleic acid sampling analysis, pathologic examination and special damage models.
Description
Technical field
The invention belongs to the life sciences experimental study and use the device technique field.
Background technology
In the life sciences experimental study, needing to use can be to the device of cerebral tissue living body sampling (to organ and accurately location and the sampling of nuclear group) and special focus modeling.Application number is that 01212276.9 Chinese patent file has been announced a kind of " biopsy gun for vacuum circular cutting ", this device is by negative pressure-pumping, it is a kind of instrument of drawing materials of tumor examination, not only require to support the use with suction device for medical use, and be not suitable for the sampling of cerebral tissue, because: the sampling quantity of negative pressure-pumping is difficult to control to be grasped, and easily damages surrouding brain tissue; The structure of its circular cutter can not be cut the cerebral dura mater that some brain district covers; Its needle point is sharp edge shape, easily punctures blood vessel in the process of inserting cerebral tissue, causes intracerebral hemorrhage.
Summary of the invention
The object of the present invention is to provide a kind of energy to be used for microcomponent's sampler of brain.
Apparatus of the present invention include:
One conduit;
One inserts the nook closing member that can move behind the conduit, and nook closing member one end is spherical crown or ellipsoid is crown, and the other end is established the spacing head that can limit the degree of depth of inserting conduit;
One inserts the sampling tube that can move behind the conduit, and sampling tube one end band saw dentation blade and inside pipe wall are threaded, the other end establish the degree of depth that can limit the insertion conduit, hollow and uncovered spacing head, this cavity of spacing docks perforation with the sampling tube cavity;
One peeling knife that behind spacing insertion sampling tube of sampling tube, can rotate, peeling knife one end is blade, the other end is established the spacing head that can limit the degree of depth of inserting sampling tube, establishes the hands handle on this spacing head;
Nook closing member and sampling tube do not contain the length of spacing head part all greater than catheter length, and the length that peeling knife can insert sampling tube is identical with the total length of the spacing head of sampling pipe racks.
As alternative parts, apparatus of the present invention can be pasted the stifled core of conduit that pipe inner wall moves after can also comprising an insertion conduit, stifled core one end of conduit is cylindric, the other end is established the spacing head that can limit the degree of depth of inserting conduit, and the length that the stifled core of conduit does not contain spacing head part is identical with the length that sampling tube does not contain spacing head part.
The use of apparatus of the present invention: first nook closing member inserted conduit, then insert in the lump the animal head, allow the nook closing member end gently be pressed in the destination organization surface.A/C is extracted nook closing member, and sampling tube is inserted conduit.Light press sampling tube and fast rotational a few, cut tunicle.Continue gently to press and rotate sampling tube it is moved down, behind the emplacement depth arrival brain target position by spacing head, rotate again sampling tube 3-10 circle, allow the target cerebral tissue be managed female thread and push in the pipe.With spacing the uncovered insertion sampling tube of peeling knife from sampling tube, rotate peeling knife 2-3 circle, cut off contacting of the interior tissue of female thread and lower covering weave.Conduit, sampling tube and peeling knife are together slowly taken out, take out peeling knife, can go out sampling tissue from spacing uncovered water filling of sampling tube.
If need to make cavity at the specific part of brain, then allow catheter retaining in brain, thereby the stifled core of conduit is inserted conduit blocks the cavity that sampling area stays, extract the stifled core of conduit after several days, the conduit below can form a cylindrical cavity, can supply the implantable neural stem cell, or put into particular chemicals etc. and come research experiment.
The beneficial effect of apparatus of the present invention: the microcomponent's sampler that provides a kind of energy to be used for brain, processing ease, tissue injury is little, precision is high, simple in structure, low cost of manufacture can be used for carrying out the foundation of the sampling analysis of live body nucleic acid, pathologic finding and special damage model.

The specific embodiment
See the embodiment of Fig. 1～6.The parts that the present embodiment device is made by following rustless steel form:
It is crown that nook closing member 2, one ends are ellipsoid, and the other end is established spacing 3 that can limit the degree of depth of inserting conduit 1,0.8 millimeter of nook closing member 2 bar section diameter, and the length that does not contain spacing 3 parts is 36 millimeters.
Stifled core 12, one ends of one conduit are cylindric, and the other end is established spacing 13 of the degree of depth that can limit insertion conduit 1, and conduit blocks up core 12, and not contain the length of spacing 13 parts identical with the length that sampling tube 4 does not contain spacing 7 parts.
The present embodiment device is used for carrying out the position sampling analysis of macaque brain stem inferior colliculus and making cavity work, and result of use is fine.
