Description
Technical field
The utility model belongs to technical field of medical instruments, more particularly, to a kind of biopsy of brain aspirator.
Background technology
For the focus of brain, before not clear and definite pathological diagnosis, therapeutic scheme should not be arbitrarily determined, it is swollen for brain encephalic
Knurl, the rate of accuracy reached more than 95% of brain biopsy diagnosis, and for some special nature pathologies such as inflammation, demyelinating disease, AIDS
Deng the accuracy rate of biopsy diagnosis can also be up to more than 85%, and brain biopsy diagnosis are often conclusive.Biopsy of brain is taken out
Haustorium is the usual means of brain biopsy, but existing biopsy device cannot be sampled to different directions, the sample number of acquisition
The less and sharp when in use puncture portion of amount easily causes expendable loss to brain, and security performance is poor.
The content of the invention
The purpose of this utility model is for the problems referred to above, there is provided a kind of biopsy of brain aspirator, with simple structure, operation
The advantage of safety.
To reach above-mentioned purpose, the utility model employs following technical proposal：This biopsy of brain aspirator, including suction group
Part, is connected with dismountable sample storage bottle on described pumping components, be removably connected with sidepiece and have on described sample storage bottle
The absorption syringe needle of opening, described pumping components include the outer sleeve with inner chamber, be provided with and take out in the inner chamber of described outer sleeve
Pull bar, is connected with piston, the pull for preventing pull excessive is provided between described pumping rod and outer sleeve on described pumping rod
Control structure.
Preferably, described one end for drawing syringe needle for inserting is to justify puncture portion that is blunt and closing, described absorption
The other end grafting of syringe needle is connected with sample storage bottle and with inside sample storage bottle.
Preferably, described pull control structure includes the internal thread being arranged in outer sleeve, on described pumping rod
It is provided with the external screw thread with screw-internal thread fit.
Preferably, described pumping rod is located at the one end outside outer sleeve is provided with rotation dish, set in described rotation dish
There is rotation holding rod.
Preferably, the smooth section positioned at internal thread front end is provided with described outer sleeve, described piston is arranged at flat
In sliding section.
Compared with prior art, the utility model has the advantage of：By opening up for taking in the sidepiece for drawing syringe needle
Different directions can be sampled on same target spot by the opening of sample, and be open in strip, and the amount of sampling is more, while
Justify blunt blind end in site of puncture, it is to avoid the damage to cerebral vessels, security performance is high, while pull control structure can be controlled
The speed of sample is produced, prevents that drawing velocity is too fast to cause brain injury.
Description of the drawings
Fig. 1 is the structure chart of the biopsy of brain aspirator that the utility model is provided.
Specific embodiment
As shown in figure 1, this programme includes pumping components 1, it is characterised in that dismountable storage is connected with pumping components 1
Sample bottle 2, is removably connected with the absorption syringe needle 3 that sidepiece has opening 31 on sample storage bottle 2, pumping components 1 are included with inner chamber
Outer sleeve 11, pumping rod 12 is provided with the inner chamber of outer sleeve 11, piston 4, pumping rod 12 and overcoat on pumping rod 12, is connected with
The pull control structure 13 for preventing pull excessive is provided between cylinder 11.This programme by draw syringe needle 3 sidepiece open up for
Different directions can be sampled on same target spot by rotating absorption syringe needle 3, and be open 31 in length by the opening 31 of sampling
Strip, the amount of sampling are more, while pull control structure can control the speed for sampling, prevent that drawing velocity is too fast to cause brain
It is impaired.
Specifically, one end that drawing syringe needle 3 is used to insert is to justify puncture portion 32 that is blunt and closing, draws the another of syringe needle 3
One end grafting is connected with sample storage bottle 2 and with inside sample storage bottle 2, while the blunt blind end of 32 circle of position of puncture portion, it is to avoid inhale
Damage of the syringe needle 3 to cerebral vessels is taken, security performance is high.
Specifically, pull control structure 13 includes the internal thread a being arranged in outer sleeve 11, pumping rod 12 be provided with
The external screw thread b that internal thread a coordinates.
Specifically, pumping rod 12 is located at the one end outside outer sleeve 11 and is provided with rotation dish 13, and rotation dish 13 is provided with and turns
Dynamic holding rod 14.
Specifically, the smooth section 15 positioned at internal thread a front ends is provided with outer sleeve 11, piston is arranged at smooth section 15
It is interior, with good sealing property, improve the efficiency of sampling.
Specific embodiment described herein is only explanation for example to the utility model spirit.The utility model institute
Category those skilled in the art can make various modifications or supplement or using similar to described specific embodiment
Mode substitute, but without departing from it is of the present utility model spirit or surmount scope defined in appended claims.
