Abstract
The utility model discloses a tumour sampler, including the cylinder, cylinder inside is provided with first piston, the export of cylinder has the syringe needle through threaded connection, inside first spacing ring and the second spacing ring of being provided with of syringe needle to be provided with the second piston between first spacing ring and second spacing ring. This tumour sampler promotes the second piston through the first piston production high pressure that promotes in the cylinder, the second piston will puncture the syringe needle through the puncture needle bar again and release the syringe needle, and get into focus department along with the syringe needle, the negative pressure that the rethread promoted the first piston production in the cylinder stimulates the second piston, negative pressure that the syringe needle front end produced is then inhale the tissue of focus department, the in -process that the puncture needle bar was retrieved along with the second piston, the tissue that sucks in the syringe needle and the contact between the outside tissue will be cut off to the shear force that produces between overhead barb of the pjncture needle of puncture needle bar front end and the syringe needle.
Description
Technical field
This utility model relates to technical field of medical instruments, is specially a kind of tumor sampler.
Background technology
At present, the clinical inspection to tumor generally adopts cytolgical examination and histological examination method, cytolgical examination checks with the cell of Fine needle aspiration affected area, histological examination rule makes it produce negative pressure by the piston promoted in syringe, the cell of affected area is sucked in syringe needle, then cut off the cell of affected area by the barb cutter stretched in syringe needle and suck contacting between syringe needle cell tissue, but this method is when implementing, because the pin chamber in syringe needle is too small, the barb cutter stretched in syringe needle may be caused being sucked syringe needle cell tissue release syringe needle by negative pressure and sample unsuccessfully, for this reason, we propose a kind of tumor sampler.
Utility model content
The purpose of this utility model is to provide a kind of tumor sampler, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of tumor sampler, comprise syringe, described syringe inside is provided with first piston, and first piston is connected with the one end of the piston rod stretched in syringe, the outlet of described syringe has been threaded connection syringe needle, described needle wall is provided with the first spacing ring and the second spacing ring, and between the first spacing ring and the second spacing ring, be provided with the second piston, described second piston is connected with one end of the puncture shank through the second spacing ring, the described puncture shank other end extends to syringe needle outside and is connected with the barbed conical piercing needle of band.
Preferably, the front end of described syringe needle is frustum, and the slope of frustum is identical with the conical surface slope of piercing needle.
Preferably, the outer surface of described second piston is provided with sealing ring.
Preferably, the surface of described second spacing ring is provided with ventilative through hole.
Preferably, the diameter of described puncture shank is identical with the penetration hole diameter on the second spacing ring.
Compared with prior art, the beneficial effects of the utility model are: this tumor sampler produces high pressure by the first piston promoted in syringe and promotes the second piston, piercing needle is released syringe needle by puncture shank again by the second piston, and enter affected area with syringe needle, the negative pressure produced by the first piston promoted in syringe again pulls the second piston, the cell tissue of affected area then sucks by the negative pressure that needle tip produces, in the process that puncture shank reclaims along with the second piston, agnail on the piercing needle of puncture shank front end and between syringe needle the shearing that produces suck contacting between cell tissue in syringe needle and external cellular tissue by cutting off.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure: 1 syringe, 2 first pistons, 3 piston rods, 4 syringe needles, 5 first spacing rings, 6 second spacing rings, 7 second pistons, 8 puncture shank, 9 piercing needles.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
Refer to Fig. 1, this utility model provides a kind of technical scheme: a kind of tumor sampler, comprise syringe 1, syringe 1 inside is provided with first piston 2, and first piston 2 is connected with the one end of the piston rod 3 stretched in syringe 1, the outlet of syringe 1 has been threaded connection syringe needle 4, syringe needle 4 inside is provided with the first spacing ring 5 and the second spacing ring 6, and between the first spacing ring 5 and the second spacing ring 6, be provided with the second piston 7, the outer surface of the second piston 7 is provided with sealing ring, sealing ring improves the sealing of syringe 1 and syringe needle 4 inside, second piston 7 is connected with one end of the puncture shank 8 through the second spacing ring 6, the surface of the second spacing ring 6 is provided with ventilative through hole, ventilative through hole prevents the pressure between the second spacing ring 6 and the second piston 7 excessive thus causes the shank 8 that punctures cannot extended needle 4, the diameter of puncture shank 8 is identical with the penetration hole diameter on the second spacing ring 6, second spacing ring 6 of same apertures limits the direction of motion of puncture shank 8, prevent from puncture shank 8 from departing from its direction of motion piercing needle 9 cannot be regained and cause and sample unsuccessfully, puncture shank 8 other end extends to syringe needle 4 outside and is connected with the barbed conical piercing needle 9 of band, high pressure is produced to promote the second piston 7 by the first piston 2 promoted in syringe 1, piercing needle 9 is released syringe needle 4 by puncture shank 8 again by the second piston 7, and enter affected area with syringe needle 4, the negative pressure produced by the first piston 2 promoted in syringe 1 again pulls the second piston 7, the cell tissue of affected area then sucks by the negative pressure that syringe needle 4 front end produces, in the process that puncture shank 8 reclaims along with the second piston 7, agnail on the piercing needle 9 of puncture shank 8 front end and between syringe needle 4 shearing that produces suck contacting between cell tissue in syringe needle 4 and external cellular tissue by cutting off, the front end of syringe needle 4 is frustum, and the slope of frustum is identical with the conical surface slope of piercing needle 9, the front end of syringe needle 4 be frustum identical with the slope of the conical surface of piercing needle 9 time, shearing between syringe needle 4 and piercing needle 9 is maximum.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
