Below in conjunction with drawings and Examples, this utility model is further described.
As shown in figures 1-8, biopsy function percutaneous puncture device got by this band, comprises sampling outer tube 1, puncture needle core 2, degree of depth screens 3, protective casing 4, and pipe 5 in sampling; Sampling outer tube 1 comprises Sampled Hand Grip 6, straight tube 7, teeth portion 8, first recess 9, second recess 10,3rd recess 11, first projection the 12, four recess 13, Sampled Hand Grip internal thread part 14, Sampled Hand Grip external thread part 15, teeth portion 8 is placed in the end of straight tube 7, and Sampled Hand Grip 6 and straight tube 7 connect as one, and the first recess 9, second recess 10, the 3rd recess 11, first projection 12, the 4th recess 13 are arranged on Sampled Hand Grip 6, Sampled Hand Grip internal thread part 14 is arranged on the side of Sampled Hand Grip 6, and Sampled Hand Grip external thread part 15 is arranged on the opposite side of Sampled Hand Grip 6; After in sampling, required specimen embraced by pipe 5, the teeth portion 8 of sampling outer tube 1 cuts this specimen lower, is convenient to sample this; Teeth portion 8 is annular, and teeth portion 8 comprises multiple cutting edge, is preferably 5-7 cutting edge.
Puncture needle core 2 comprises pin stem 16, nook closing member handle 17, and pin stem 16 and nook closing member handle 17 connect as one, and the end of pin stem 16 is set to tapered point; Puncture needle core 2, for prick skin, vertebral body, enters ad-hoc location; Protective casing 4, sampling outer tube 1 surface are provided with scale; As shown in Figure 4, it is in operation process in degree of depth screens 3, and utilize the scale on protective casing 4, sampling outer tube 1, the clear lower pin degree of depth instructing puncture needle core 2, to avoid piercing through vertebral body, brings negative effect to operation; Protective casing 4 comprises cannula portion 18, protective casing connecting portion 19, and protective casing external thread part 20; Cannula portion 18 is connected with protective casing connecting portion 19, and protective casing external thread part 20 is arranged on the end of protective casing connecting portion 19; Degree of depth screens 3 is enclosed within the outside of the cannula portion 18 of protective casing 4, and one end of degree of depth screens 3 is resisted against one end of protective casing connecting portion 19; In sampling, pipe 5 comprises main body 21, slide block 22, and main body 21 comprises main body shank 25, body recess 24 and hooks blade 23, hooks the end that blade 23 is arranged on body recess 24, slide block 22 is arranged the 5th recess 27, second projection 26; Hook blade 23 and comprise multiple hook-shaped sword, at least one hook-shaped sword is end is point, and at least one hook-shaped sword is end is arc; Be preferably two hook-shaped swords, one of them hook-shaped sword is end is point, and another hook-shaped sword is end is arc.
As shown in Figure 9, slide block 22 can slide up and down at main body shank 25 slide block movement schematic diagram; Protective casing 4 is enclosed within outside sampling outer tube 1, and is connected with Sampled Hand Grip internal thread part 14 by protective casing external thread part 20; In sampling, pipe 5 is arranged on sampling outer tube 1 inside; It is inner that puncture needle core 2 is arranged on pipe 5 in sampling; First protruding 12 of sampling outer tube 1 is abutted against each other together with the second projection 26 of pipe 5 in sampling, makes pipe 5 in sampling cannot by the bottom of the first recess 9 to sampling outer tube 1.The width of the first projection 12 is equal with the width of the second projection 26.As shown in figs. 10-12, because slide block 22 is arranged to said structure, pipe 5 in sampling is utilized to sample this time, can by slide block 22 upward sliding (or slide downward), and then make pipe 5 in sampling by the bottom of the first recess 9 to sampling outer tube 1, now, upper and lower both sides second projection 26 embeds the 3rd recess 11 and the second recess 10(or upper and lower both sides second projection 26 respectively and embeds the second recess 10 and the 3rd recess 11 respectively).In order to make pipe 5 in sampling cooperatively interact with sampling outer tube 1, the width of the second projection 26 is equal with the width of the 3rd recess 11, second recess 10 respectively.
Introduce the sampling theorem that biopsy function percutaneous puncture device got by this band below, as shown in figs. 10-12, by slide block 22 upward sliding (or slide downward), pipe 5 in sampling is pressed downwards, in sampling process, when in sampling, pipe 5 travels forward, in sampling, the interaction process of the hook blade 23 of pipe 5 and the teeth portion 8 of sampling outer tube 1 as shown in figure 13, realizing principle is: when in sampling, pipe 5 moves downward, insertion specimen is inner, because the internal diameter sampling outer tube 1 end diminishes, under the squeezing action of sampling outer tube 1 end, in sampling, the hook blade 23 of pipe 5 is out of shape to the inside, thus tightly embrace specimen, after required specimen embraced by pipe 5 in sampling, rotate Sampled Hand Grip 360 degree, cut the connection bit below specimen by the teeth portion 8 sampling outer tube 1 end.
The operational approach of biopsy function percutaneous puncture device got by this band, and operating procedure is as follows:
(1) as shown in figure 14, this band is got biopsy function percutaneous puncture device and break through cortical bone, arrive when needing sampling starting position and remove puncture needle core 2.
(2) as shown in figure 15, after removing puncture needle core 2, degree of depth screens 3 is pushed into and is close to skin site.
(3) as shown in figure 16, this band is got under biopsy function percutaneous puncture device after pin to desired depth, the slide block 22 of pipe 5 in sampling of sliding up or down.
(4) as shown in figure 17, press pipe 5 in sampling downwards and carry out specimen locking, rotate Sampled Hand Grip 360 degree, connection bit below cutting specimen.
(5) as shown in figure 18, take out pipe 5 in sampling, complete living body sampling.
But, those of ordinary skill in the art will be appreciated that, above embodiment is only used to this utility model is described, and be not used as restriction of the present utility model, as long as in spirit of the present utility model, all will drop in Claims scope of the present utility model the change of the above embodiment, modification.
