Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment 1
As shown in Figure 1, the present embodiment is a kind of collection anesthetic needle, puncture needle, positioning needle Trinity sting device of the use when carrying out diagnosis and treatment to mammary gland, comprises sleeve pipe stylophore 1, puncture needle 2 and positioning needle 3 three major parts.
Sleeve pipe stylophore 1 comprises soft sleeve pipe 12 and is arranged on the handheld terminal 11 of sleeve pipe 12 initiating terminal.Is provided with the passage 14 is communicated with sleeve pipe 12 in the middle of handheld terminal 11, puncture needle 2 and positioning needle 3 can be inserted in pipe by this passage 14, also can subcutaneously output other apparatus for diagnosis and treatment, medicine in soft tissue or body.The sleeve pipe 12 of sleeve pipe stylophore 1 can be rubber tube or silica gel tube and other soft pipeline, and handheld terminal 11 generally adopts PVC material or PP material, and transparent is good.The side of the handheld terminal 11 of sleeve pipe stylophore 1 is provided with the 3rd interface 15, tilting towards handheld terminal 11 direction to sleeve pipe stylophore 1 of 3rd interface 15, when puncture needle 2 is sleeved on sleeve pipe stylophore 1, 3rd interface 15 direction is less than 90 ° with the angle towards puncture needle 2 Handheld Division 21, like this, when puncture needle 2 is not sleeved in sleeve pipe stylophore 1, to be convenient to by the 3rd interface 15 through sleeve pipe 12 to organizing delivering medicament, 3rd interface 15 communicates with passage 14, the device being similar to check valve sample is provided with in the 3rd interface 15, make to be injected in passage by the 3rd interface 15 and make agent and other medicament, can not aspirate in passage.
Puncture needle 2 comprises the hollow needle body 22 of rigidity and is arranged on the Handheld Division 21 of hollow needle body 22 initiating terminal, Handheld Division 21 towards hollow needle body 22 side, there is the first interface 25 matched with handheld terminal 11 outer lateral side 13; Hollow needle body 22 end is provided with the sword head 23 of cutting sth. askew; Body 22 is inserted in sleeve pipe 12 from passage 14, and when first interface 25 and handheld terminal 11 outer lateral side 13 match, sword head 23 stretches out from the front end of sleeve pipe 12; The hollow needle body 22 of puncture needle 2 is general by rustless steel, and Handheld Division 21 equally with the handheld terminal 11 of sleeve pipe stylophore 1 can adopt PVC material or PP material, and transparent is good.Owing to there being sword head 23, therefore, when sleeve pipe stylophore 1 be enclosed within puncture needle 2 outer time, the soft sleeve pipe 12 of piercing process middle sleeve stylophore 1 also penetrates into lesion tissue with the hollow needle body 22 of puncture needle 2, and puncture needle 2 itself slowly can be extracted out from soft sleeve pipe 12, at the reverse side towards hollow needle body 22 side of the Handheld Division 21 of puncture needle 2, also be provided with second interface 24 that to be connected with syringe 4 needle tubing, some medicines can be added to the lesion tissue of site of puncture by syringe 4, as anesthetis etc., as shown in Figure 6.When not accessing syringe 4 as shown in Figure 4, need to add a lid, in order to avoid pollute at the second interface 24 place.
Positioning needle 3 is a solid needle, comprise needle body 31 and be arranged on the barb 32 of needle body front end, in the present embodiment, positioning needle 3 itself be a thinner solid needle as shown in Figure 3, conveniently, one end relative with barb 32 on positioning needle 3 needle body 31 is also provided with severity control mark 33, and severity control mark 33 is flexibly connected with needle body 31, after positioning needle 3 places from sleeve pipe stylophore 1, as shown in Figure 5, can remove, like this, sleeve pipe stylophore 1 just can be extracted out.The needle point of barb 32 has related device, just row (to the motion of needle point direction) does not open, and (open when moving to backshank direction, needle body has related device in pumpback, needle point is made to be fixed on inside tumor, to prevent from scratching patient's finger tip when peeling off excision lump.
The product of the present embodiment is suitable for carrying out diagnosis and treatment activity under ultrasound wave display, therefore, needle body 31 component of the sleeve pipe 12 of sleeve pipe stylophore 1, the hollow needle body 22 of puncture needle 2 and positioning needle 3 is provided with the special surface for ultrasonic display, and special polishing is carried out on surface, under microscope, have marked feature.Special polishing is carried out to needle body 31 surface of the sleeve pipe 12 of sleeve pipe stylophore 1, the hollow needle body 22 of puncture needle 2 and positioning needle 3, under microscope, has marked feature.The needle body 31 that positioning needle 3 starts from barb 32 tip is provided with equidistant mark (1cm large-spacing circle, be divided into 10 1mm down scales, with colour code degree of depth such as red, orange, yellow, green, blue, blue, purple), investigate thoroughly in order to patient, avoid barb to hurt finger.As shown in Figure 2.
Special polishing is carried out on needle body 31 and barb 32 surface of hollow needle body 22, sword head 23 and positioning needle 3, makes its rough surface, under microscope, has marked feature; And x-ray molybdenum target can show needle body 31 and the barb 32 of the hollow needle body 22 of puncture needle 2, sword head 23 and positioning needle 3.The tiny right-handed screw that barb 32 needle body develops under iconography is housed, locate, backpitch as shown in Figure 2, make barb be equidistant reflection to all directions, protect this 15cm length positioning needle molding standard.Barb 32 has related device, and in sleeve pipe stylophore, just row (to the motion of needle point direction) does not open; Pumpback (when moving to backshank direction) after entering focus of puncturing is opened.
In the present embodiment, the puncture needle of whole sting device is made up of the gum cover pipe soft sleeve pipe 12 of said sleeve pipe stylophore 1 (namely above) of outside and the hollow pipe puncture needle (i.e. the hollow needle body 22 of the puncture needle 2 of the inside) of the inside.The soft sleeve pipe 12 of the present embodiment, the tubular body be formed in one, its top is hard gum cover PVC, is soft tube below sleeve pipe.Central authorities are the hollow needle body of puncture needle 2, are longer than hard rubber trocar.
Before Needle localization, to focus and the local infiltration anesthesia of surrounding tissue row.On second interface 25 of the puncture needle 2 of the present embodiment, end connector can be connected syringe body, is used as syringe needle and is used as local anaesthesia.
Position operating process: ultrasound guidance, after puncture needle is slowly thrust target focus, operator arrests positioning needle 3 Handheld Division, the blade 23 of the hollow needle body 22 of ultrasound observation puncture needle 2 and the position relationship of focus, under guiding, blade 23 is aimed at focus and periphery appropriate area is slowly thrust, until location blade 23 end enters intralesional.Extract the hollow needle body 22 of puncture needle 2, be detained the soft sleeve pipe 12 of sleeve pipe stylophore 1.By homemade aseptic positioning needle 3 by the soft sleeve pipe 12 of sleeve pipe stylophore 1, slowly thrust, iconography display is until after positioning needle 3 front end arrives at focus, slowly exit sleeve pipe stylophore 1, backward needle 3, allow barb 32 be fixed on focus.Barb 32 and the lesions position relation of ultrasonic expliciting the position pin 3, positioning needle 3 tail end covers fixing with gauze.
