Abstract
The utility model provides a low friction bone aspiration biopsy needle relates to medical field, and its main technical characteristics is equipped with sawtooth (5), (6) of taking the gradient on the ring of sleeve pipe (1) left end portion, and its right-hand member is equipped with handle (2), and nook closing member (4) cooperatees with sleeve pipe (1), passes sleeve pipe (1) from the right side left side, installs in it, and the left end of nook closing member (4) is equipped with syringe needle (7) of a pyramid, exposes outside sleeve pipe (1), and its right-hand member is equipped with handle (3). The utility model discloses big to the tissue specimen of getting, it is light because of the little compression of frictional force, and the diagnosis coincidence rate is high, its reasonable in design, simple structure, convenient operation.
Description
This utility model provides a kind of low friction bone aspiration biopsy pin, relates to medical domain.Be specifically related to take out in the human body apparatus of medium.
Traditional body bone tissue biopsy, the method for employing are surgical incision cutter saws or take osseous tissue inspection that the method existence creation is big, expense is high, take length, and the big shortcoming of chance of tumor diffusion.Though have the people to take the method for other biopsies in recent years, more preceding method has had the advantage of bigger progress.But the tissue mass of getting is little limits to owing to also there is institute in this method, and because of its apparatus friction is big, to the tissue compression important disadvantages, so the coincidence rate of pathological diagnosis is subjected to very big influence.Little as No. 902140272 " spiral tumor biopsy pin " institutes of Chinese patent specimen amount of getting, broken and limitation; No. 902175599, Chinese patent, " core sleeve sampler ", though several sampling methods are arranged, the specimen of getting is organized little and is limited to, big with the internal surface of sleeve pipe friction because of bone sample surface again, compression is serious, influences the coincidence rate of pathological diagnosis.
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of reasonable in design, simple in structure, and it is large and complete to take a sample, and friction is little, makes a definite diagnosis the high low friction bone aspiration biopsy pin of coincidence rate.
The technical solution adopted in the utility model is the sawtooth that is provided with the band gradient on the annulus of telescopic left part, is provided with a pyramid syringe needle at the nook closing member left end, and the merging that matches of nook closing member and sleeve pipe leaves that the structural design of certain interval realizes.
Major technique feature of the present utility model is sawtooth (5), (6) that are provided with the band gradient on the annulus of sleeve pipe (1) left part, its right-hand member is provided with handle (2), nook closing member (4) matches with sleeve pipe (1), right-to-left passes sleeve pipe (1), install within it, the left end of nook closing member (4) is provided with pyramidal syringe needle (7), is exposed to outside the sleeve pipe (1), and its right-hand member is provided with handle (3).
The sawtooth (5) of the band gradient on the left part annulus of sleeve pipe (1), (6) tilt in the direction of the clock, and its gradient β is 50 degree, and between sawtooth (5) and (6) every a tooth, be sawtooth (5), inwardly dial a gradient from the tooth root portion of sawtooth (6), its gradient is 75 degree; Its sleeve pipe (1), nook closing member (4) are made with stainless steel; The handle (2) of sleeve pipe (1), the handle (3) of nook closing member (4), respectively with argon arc welding with itself and sleeve pipe (1), nook closing member (4) welds together.
The utility model has the advantages that: (1), this utility model is light because of the little compression stage of friction to getting tissue specimen, the diagnosis rate height.By 21 comparative study with general trephine type puncture needle, its result has the difference of highly significant.（P＜0·01）。Through pathologic finding, without improved puncture needle,, have only 62% can make tentative diagnosis or clarify a diagnosis, and tissue specimen that this utility model is got all can be clarified a diagnosis because of tissue is compressed, diagnosis rate can reach 100%.(2) tissue specimen that this utility model is got, large and complete of volume can be represented the overall picture of its osteopathia kitchen range, obviously is better than other sampling apparatuses, thereby has improved the coincidence rate of diagnosis.(3) modern design of the present utility model, reasonable, simple in structure, easy to operate, wound is little, and expense is low, and the patient suffering is few.Be easy to popularize in hospitals at different levels.
Description of drawings:
Fig. 1 is a structural front view of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the expansion sketch map of Fig. 2;
Fig. 4 is a structure vertical view of the present utility model;
Below in conjunction with the embodiment in the accompanying drawing, this utility model is described in detail.
With reference to figure 1, Fig. 2, Fig. 3, Fig. 4, this utility model is by sleeve pipe (1), handle (2), sawtooth (5), (6) and the nook closing member (4) of band gradient, handle (3), syringe needle compositions such as (7).In the present embodiment, sleeve pipe (1), nook closing member (4) are used the stainless steel manufacturing, its handle (2), handle (3) with argon arc welding respectively with sleeve pipe (1), nook closing member (4) welds together; In the present embodiment, sawtooth (5), (6) of band gradient on the annulus of sleeve pipe (1) left part, tilt in the direction of the clock, its gradient β is 50 degree, is sawtooth (5) every a tooth between its sawtooth (5), (6), a gradient is inwardly dialled by tooth root portion from sawtooth (6), its gradient is 75 degree, to guarantee the making internal diameter of the diameter of the specimen post of being got less than sleeve pipe (1), to reduce its friction, this utility model is easy to operate, also is suitable for doing bone decompression or drain and uses.
