Description
Technical field
This utility model belongs to medical instruments field, particularly relates to the improving technology of Nonpalpable Breast Lesions positioning needle.
Background technology
At present, existing Nonpalpable Breast Lesions mainly relies on the preoperative location of Intraductal lesions, but the plentiful degree of breast, tissue looseness's degree is different, easily causes positioning needle to be shifted and (as breast waves when patient walks or rises and retires, protects not good; Medical practitioner sterile or misoperation etc.), cause operation difficulty even failed.Simple syringe methylene blue staining can be used for breast lesion location, and without displacement risk, but it is only limitted to the location of ultrasound guidance, locates under cannot being applied to breast molybdenum target or nuclear resounce.
Summary of the invention
For the defect existed in prior art and technical problem, this utility model provides a kind of breast lesion positioning needle, addition of methylene blue staining positioning function, realizes positioning needle/dyeing Dual positioning, reduce the displacement risk of simple positioning needle location, also expand the scope of application of methylene blue staining.
For solving the problems of the technologies described above, this utility model have employed following technical scheme: a kind of breast lesion positioning needle, comprises puncture needle, syringe and steel pipe, and described syringe comprises syringe, be located at the piston rod in syringe and be located at the union joint of syringe head; Described Puncture needle sleeve is connected on the union joint of syringe head, comprises puncture needle body and is located at the positioning guide wire in puncture needle body; Described steel pipe is located in syringe, and its tail end is through the piston rod in syringe, and front end is located in union joint, and front end is also provided with the through hole for liquid in the syringe that circulates.
As preferably, the outer of front end of described steel pipe is arranged with outer tube, and steel pipe and outer tube are directly connected and fixed by multiple fixed cylinder, and forms multiple through hole.
As preferably, described steel pipe front end thickeies, and is provided with at thickening position the through hole for liquid in the syringe that circulates run through.
As preferably, in described syringe, be provided with methylthioninium chloride injection.
As preferably, described positioning guide wire is formed by least two strands of steel wire windings, and its head separately can form hook in its natural state.
As preferably, described steel pipe is made of plastics.
As preferably, the front end of described steel pipe is also provided with sealing valve block, thus can prevent the backflow of methylene blue.
Beneficial effect: relative to prior art, this utility model is simple and practical, achieves methylene blue staining location and positioning guide wire Dual positioning, avoids the location caused due to individual variation to be forbidden, reduces displacement risk.

Detailed description of the invention
Below in conjunction with accompanying drawing and with specific embodiment, illustrate this utility model further.These embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of this utility model, after having read this utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As shown in Figure 1, breast lesion positioning needle of the present utility model, comprises puncture needle, syringe and steel pipe, and described syringe comprises syringe, be located at the piston rod in syringe and be located at the union joint of syringe head; Described Puncture needle sleeve is connected on the union joint of syringe head, comprises puncture needle body and is located at the positioning guide wire in puncture needle body; Described steel pipe is located in syringe, its tail end is through the piston rod in syringe, front end is located in union joint, and front end is also provided with the through hole for methylene blue in the syringe that circulates, thus make methylene blue can from the through hole of steel pipe front end through and be expelled to breast lesion location through puncture needle and carry out labelling.
Preferably embodiment, as shown in Figure 4, outer tube is set in the periphery of the front end of described steel pipe, and outer tube and and steel pipe between to arrange fixed cylinder fixing as support, thus form multiple through hole between outer tube and steel pipe front end, thus methylene blue is can be used for pass through.Another embodiment as shown in Figure 5 again, the front end of steel pipe can be thickeied process, thus at the multiple through hole parallel with steel pipe of the arranged outside thickening position for methylene blue circulation, further, steel pipe front end after thickening and between steel pipe body junction can be in smoothing junction (namely, increase gradually from body toward the thickness of front end), also can be increase suddenly.Further, the material of steel pipe can be rustless steel, also can be plastics.
During operation, check out Nonpalpable Breast Lesions by breast ultrasound, breast molybdenum target or mammary gland MR, and the syringe needle of guided puncture needle body is to lesions position, a little to lesions position injection methylene blue solution through side injection orifice by 5ml syringe, carry out dyeing location; Then, slowly exit puncture needle body, now the head of positioning guide wire is opened, and hooks lesions position; So far, lesion localization operation terminates.
