技术领域technical field
本发明涉及医疗检测器械设备技术领域，尤其涉及一种经皮穿刺活检针。The invention relates to the technical field of medical detection equipment, in particular to a percutaneous biopsy needle.
背景技术Background technique
随着医疗水平的不断发展，近几年通过超声引导下细针穿刺细胞学活检在日常医疗中的应用越来越多。该方法是在超声监视下应用，通过提插方式获得浅表器官组织靶目标细胞进行病理诊断，如乳腺、甲状腺、肾、肝脏、淋巴结等，是早期诊断靶目标良恶性的最快捷、简便与安全的方法。相对于以往的组织学活检而言，具有损伤小、风险小、结果同样可靠等优点。这就涉及到一个非常重要的工具——穿刺针。With the continuous development of the medical level, ultrasound-guided fine-needle aspiration cytology biopsy has been more and more used in daily medical treatment in recent years. This method is applied under ultrasonic monitoring, and the target cells of superficial organ tissues are obtained by lifting and inserting for pathological diagnosis, such as breast, thyroid, kidney, liver, lymph nodes, etc. Safe way. Compared with the previous histological biopsy, it has the advantages of less damage, less risk, and equally reliable results. This involves a very important tool - the puncture needle.
目前所用的穿刺针为中空的极细的圆管状结构，外径14～25G依次对应的外径尺寸为2.1mm～0.4mm，可配有实体针芯，实体针芯刚好填充穿刺针的中空部分，实体针芯的作用是在穿刺过程中防止组织碎屑及其他非靶目标组织进入穿刺针的中空部分内，干扰或影响诊断结果；之所以超声引导下穿刺针细胞学活检安全，是因为穿刺针的穿刺路径能够始终在操作医师直视下进行，在实际穿刺过程中，操作医师必须一只手把握探头，另一只手执穿刺针，如果使用不带实体针芯的的穿刺针，组织碎屑或非靶目标细胞则很容易进入穿刺针内，干扰或影响对靶目标良恶性判定的准确性；如果使用带实体针芯的穿刺针可尽量避免上述情况，但也存在一定的实际应用问题，当穿刺针到达靶目标时需拔出实体针芯，如果此时操作医师放弃对穿刺针的把持来拔出实体针芯，并把针芯放到安全的地方，由于软组织的柔软性和弹性，穿刺针就会发生移位，损伤靶目标周围重要组织和器官的风险大大增加。The puncture needles currently used are hollow and extremely thin round tubular structures, with an outer diameter of 14-25G, corresponding to an outer diameter of 2.1mm-0.4mm, which can be equipped with a solid needle core, which just fills the hollow part of the puncture needle , the role of the solid needle core is to prevent tissue debris and other non-target tissues from entering the hollow part of the puncture needle during the puncture process, interfering with or affecting the diagnostic results; the reason why the ultrasound-guided needle cytology biopsy is safe is because the puncture The puncture path of the needle can always be carried out under the direct vision of the operator. During the actual puncture process, the operator must hold the probe with one hand and the puncture needle with the other hand. If a puncture needle without a solid needle core is used, the tissue Debris or non-target cells can easily enter the puncture needle, which interferes or affects the accuracy of judging whether the target is benign or malignant; if a puncture needle with a solid needle core is used, the above situation can be avoided as much as possible, but there are also certain practical applications The problem is that when the puncture needle reaches the target, the solid needle core needs to be pulled out. If the operator gives up holding the puncture needle to pull out the solid needle core at this time, and put the needle core in a safe place, due to the soft tissue softness and If there is no elasticity, the puncture needle will be displaced, and the risk of damaging important tissues and organs around the target is greatly increased.
