技术领域technical field
本实用新型涉及一种医疗器械技术，尤其是一种肺结节定位穿刺针套件。The utility model relates to a medical device technology, in particular to a lung nodule positioning puncture needle set.
背景技术Background technique
肺结节是指肺内孤立性的类圆形病灶，直径小于4cm，无肺炎和局部淋巴结的增大。近年来，肺结节的患者越来越多，肺结节的早期诊断较为困难，临床上缺乏特异性，影像学上表现形态多样，良、恶性不易断定，常常造成误诊而耽误治疗。临床上对该类患者主张外科手术治疗，均取得了较好的效果。外科手术过程中，无论是采用开胸切口，还是采用胸腔镜胸部小切口手术切除肺结节，都需要在术中寻找肺结节，在胸腔镜下肺小结节的寻找，往往成为手术成败的关键，因此术前定位穿刺非常重要。Pulmonary nodules refer to solitary quasi-circular lesions in the lung, less than 4 cm in diameter, without pneumonia and enlargement of regional lymph nodes. In recent years, there have been more and more patients with pulmonary nodules. The early diagnosis of pulmonary nodules is difficult, lacks clinical specificity, and has various imaging forms. It is difficult to determine benign and malignant, which often leads to misdiagnosis and delayed treatment. Clinically, surgical treatment is advocated for such patients, and good results have been achieved. During the surgical operation, no matter whether a thoracotomy is used or a thoracoscopic small chest incision is used to remove pulmonary nodules, it is necessary to find pulmonary nodules during the operation. Finding small pulmonary nodules under thoracoscopic surgery often becomes the success or failure of the operation. Therefore, preoperative positioning of the puncture is very important.
近年来CT定位下细针肺穿刺技术应用于肺结节手术已经被医学界认同。目前，临床上肺穿刺所用的细针穿刺定位后，术中极易发生移位，甚至脱落，易导致手术失败或者切除肺部组织过多，不甚理想。In recent years, the application of fine-needle lung puncture under CT positioning in pulmonary nodule surgery has been recognized by the medical community. At present, the fine-needle puncture used in clinical lung puncture is very prone to shift or even fall off during the operation, which may easily lead to operation failure or resect too much lung tissue, which is not ideal.

Together, the visceral pleura is pierced with the core needle 31 .
本实用新型的肺结节定位穿刺针套件还包括一根内芯推针，请参考图4，所述内芯推针21为中空管结构且头部没有刃头，用于推送定位导丝，如图6的定位导丝40的尾部可以插入到内芯推针的中空管中，V形倒钩露出在内芯推针的头部位置，当所述内芯推针21插入到外管针11内部，所述定位导丝的V形倒 钩折叠后塞入外管针11，所述内芯推针21的尾部与一芯针基部22相配接，利用芯针基部22的卡扣23、外管针基部13的卡槽14，将芯针基部22、外管针基部13相固定，固定后所述内芯推针21的头部露出外管针，所述定位导丝40的V形倒钩也露出外针管。The pulmonary nodule positioning puncture needle set of the present utility model also includes an inner core push needle, please refer to Figure 4, the inner core push needle 21 is a hollow tube structure and the head has no blade, and is used to push the positioning guide wire , the tail of the positioning guide wire 40 as shown in Figure 6 can be inserted into the hollow tube of the inner core push pin, and the V-shaped barb is exposed at the head position of the inner core push pin, when the inner core push pin 21 is inserted into the outer Inside the tube needle 11, the V-shaped barb of the positioning guide wire is folded and inserted into the outer tube needle 11, the tail of the inner core push pin 21 is matched with a core needle base 22, and the buckle of the core needle base 22 is used to 23. The card slot 14 of the base of the outer tube needle 13 fixes the base of the core needle 22 and the base of the outer tube needle 13. After fixing, the head of the inner core push pin 21 exposes the outer tube needle, and the positioning guide wire 40 The V-shaped barb also exposes the outer needle barrel.
在本实施例中，所述内芯推针的长度与内芯针的长度相同，在其他实施例中，所述内芯推针的长度也可以大于内芯针的长度。In this embodiment, the length of the inner core push pin is the same as that of the inner core needle, and in other embodiments, the length of the inner core push pin may also be longer than that of the inner core needle.
在具体实施例中，先将内芯针31套入到外管针11中，在CT引导及穿刺专用带呼吸门控监护仪配合引导下，将所述内芯针31、外管针11穿刺肺部小结节病灶，通过管壁的刻度测量内芯针31尖至脏层胸膜表面距离，将定位导丝剪去多余长度，使V形倒钩至导丝尾部正好与针尖至脏层胸膜距离一致。将导丝蘸水后从头部插入到内芯推针21内，直至V形倒钩抵到内芯推针21。拔出内芯针31后，将定位导丝V形尖端对折，定位导丝连同内芯推针21插入外管针11，缓慢推送至肺内，定位导丝的头部露出外管针后，定位导丝V形倒钩打开，定位导丝留在肺结节中，然后分别撤出内芯推针21和外管针11。In a specific embodiment, the inner core needle 31 is inserted into the outer tube needle 11 first, and under the guidance of CT and a dedicated puncture monitor with a respiratory gating control, the inner core needle 31 and the outer tube needle 11 are punctured. For small pulmonary nodules, measure the distance from the tip of the inner core needle 31 to the surface of the visceral pleura through the scale on the tube wall, and cut off the excess length of the positioning guide wire, so that the V-shaped barb reaches the tail of the guide wire and is exactly the same as the needle tip to the visceral pleura The distance is the same. After the guide wire is dipped in water, insert it into the inner core push pin 21 from the head until the V-shaped barb reaches the inner core push pin 21 . After pulling out the inner core needle 31, fold the V-shaped tip of the positioning guide wire in half, insert the positioning guide wire together with the inner core push needle 21 into the outer tube needle 11, and slowly push it into the lung, after the head of the positioning guide wire is exposed to the outer tube needle, The V-shaped barb of the positioning guide wire is opened, the positioning guide wire stays in the pulmonary nodule, and then the inner core push pin 21 and the outer tube needle 11 are withdrawn respectively.
现有的穿刺针都是外管针具有刃头，利用外管针刺破人体组织，但外管针是中空管结构，中空的外管针容易被人体组织堵住，且具有刃头的穿刺针长时间放置在肺结节中，可能会刺伤其他部位。而在本实用新型中，由于是通过内芯针31的刃头穿刺肺部小结节病灶，外管针不具有刃头，且所述外管针的头部端面为平面，长时间放置在肺结节中也不怕刺伤其他人体组织，不会造成病人的二次痛楚。Existing puncture needles all have outer tube needles with a blade head, which are used to puncture human tissue, but the outer tube needle is a hollow tube structure, and the hollow outer tube needle is easily blocked by human tissue, and has a blade head. If the puncture needle is placed in the lung nodule for a long time, it may puncture other parts. However, in the present utility model, since the blade head of the inner core needle 31 is used to puncture the small nodular focus of the lung, the outer tube needle does not have a blade head, and the head end face of the outer tube needle is a plane, so it is placed on the surface for a long time. Pulmonary nodules are not afraid of stabbing other human tissues, and will not cause secondary pain to the patient.
最后应说明的是：本实用新型虽然以较佳实施例公开如上，但其并不是用来限定本实用新型，任何本领域技术人员在不脱离本实用新型的精神和范围内，都可以做出可能的变动和修改，因此本实用新型的保护范围应当以本实用新型权利要求所界定的范围为准。Finally, it should be noted that: although the utility model is disclosed as above with preferred embodiments, it is not used to limit the utility model, and any person skilled in the art can make Possible changes and modifications, so the protection scope of the utility model should be defined by the claims of the utility model as the criterion.
