Specific embodiment

Below in conjunction with Figure of description, specific embodiment of the present utility model is described in further details.

For the puncture needle of Internal Medicine-Cardiovascular Dept., including enter tissue and carry out extract body hollow tubular puncture needle needle Body 200, the needle section 201 of common needle body directly chamfers formation, therefore the needle section 201 of needle body only has the function of puncturing, But when there is particulate material in the part extracted, extraction process is often obstructed, and causes extraction efficiency low, in order to improve It extracts in effect this patent scheme and extends a cutting part in the end of needle body, cutting part has both the function of puncture and cutting, cuts The end for cutting portion 203 is still tip 205, and the two sides of cutting part are then cutting edge 204, and the region between cutting part and needle section is equipped with The transition region 202 of one arc can carry out little trick and shake cutting part pair when carrying out cutting tissue to expand absorption range Tissue carries out transverse cuts, and the absorption range of such syringe needle will will increase, to get rid of or avoid graininess obstruction.

Replacement puncture needle needle body, one end of needle body are equipped with the lid 206 mating with socket, lid for convenience simultaneously Cooperated by grafting and socket removable seal, in order to protect puncture needle needle body, the protective case of a tubulose be also socketed with outside needle body, Protective case is made of polythene material, and edge is equipped with lining 208 made of plastic rubber in one end of protective case 207, lining Internal diameter is slightly less than the outdoor scene of lid, is socketed on the lid by the elasticity of lining, realizes the installation of protective case.

After carrying out in use, needle body enters lesion, the sample liquid drawn through needle body can carry out extraction dress by tubular sections It sets, tubular sections can also be used and carry out storage lesion liquid sample.Specifically, tubular sections include being wholely set with linkage section by hard Rigid section 104 made of material further include the stretch section 105 connecting with 104 other end of rigid section, and rigid section is in order to needle body Take and install, and compliant section be then when needing to draw a small amount of lesion liquid, by squeeze compliant section reach suction The purpose taken, when need it is a large amount of draw lesion liquid sample when, it is mating by slit and syringe or pass through linkage section Be tightly connected and realize with the inlet tube of extracting device, after extraction, tubular sections to want one end to carry out by end cap 300 close Envelope, when being taken, end cap is vertically taken as bottom, one end of plug as upper end, and plug is by cock body or blocks up Head be sealed, tubular sections directly as Sample preservation pipe carry out using.

In order to guarantee the flexible deformation of tubular sections, as depicted in figs. 1 and 2, the stretch section includes by polyethylene material system At, cylindric base layer 106, elastic layer 108 of the inner wall of the base layer 106 along collective's layer circumferential surface laying, the bullet Property layer be made of elastic rubber, the base layer outer peripheral surface be equipped with multiple elastic ribs 107 being spaced apart, the rib 107 one end is protruded into the rigid section 104 and is fixed, and the other end of the rib extends to the end of compliant section, described Rib flaky texture made of spring steel, each rib are fixed on the outer peripheral surface of the base layer by way of bonding On.

In one embodiment, as shown in Figure 1, connection in order to realize end cap and tubular sections, an end face of the end cap 300 It is equipped with the annular trough body 301 cooperated with linkage section wall body, the groove body inner wall is equipped with the helicitic texture cooperated with linkage section, institute End cap is stated to be threadedly coupled by screw thread with linkage section.

In one embodiment, as shown in Figure 1, the sealing 400 is made of the rubber or silica gel of elasticity, slit passes through bullet Property material effect realize sealing, sealing includes the fixed part 401 being adhesively fixed with end cap face, and the fixed part extends outwardly shape At protrusion 402, the slit 403 is located at convex center, and the through-hole of connection is equipped at the corresponding end cap central of slit.

Compared with prior art, the utility model has the beneficial effects that the aspiration end of even section and pumping equipment can be passed through It is connected and sealed, can also be attached by the slit of sealing and the air inlet of syringe by screw thread, to realize to group Knit the extraction of affected area.Can change Smoking regime rapidly and efficiently, avoid replacing different types of puncture needle and give patient's bring Pain.Syringe needle, if the lesion sample of larger particles enters needle end during suction, causes when entering correct target spot When the suction of lesion liquid is unfavorable, traversing cutting is carried out to tissue to obtain the sample liquid of target spot by the cutting edge of cutting part, is The preliminary developing in subsequent procedures conduct direction establishes in vitro to the channel in internal official jargon.

The utility model is described in detail above by specific embodiment and embodiment, but these are not structure At limitations of the present invention.In the case where not departing from the utility model principle, those skilled in the art can also be made Many modification and improvement, these also should be regarded as the protection scope of the utility model.
