Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as restriction of the present utility model.
Embodiment
Shown in Fig. 1 and Fig. 2, Fig. 1 is the structural representation of stylophore in a kind of modified model Percutaneous lung puncture pin of the present utility model, and Fig. 2 is the syndeton schematic diagram of stylophore and syringe needle in a kind of modified model Percutaneous lung puncture pin of the present utility model.
A kind of modified model Percutaneous lung puncture pin of the present utility model, comprise stylophore 1, syringe needle 2 and garter spring 3, syringe needle 2 is arranged in stylophore 1 by garter spring 3 separably, wherein, needle tubing 4 outer round surface of stylophore 1 head sets gradually some round dot grooves 91 by needle point to stylophore 1 direction, needle tubing 4 length can be 8 centimetres or 12 centimetres of two kinds of specifications, thickness is identical, and some scale marks 91 on needle tubing 4 surface comprise red spots labelling, blue round dot labelling, yellow round dot labelling, purple round dot labelling and green round dot labelling.
As shown in Figure 2, in further embodiment of the present utility model, the needle tubing that the percutaneous lung being 8 centimetres for the length of needle tubing 4 is threaded a needle, the position relationship of the scale mark on needle tubing surface is divided into as follows by needle point to stylophore 1 direction,
