Abstract

The invention discloses a percutaneous threaded marrow core bone tumor biopsy puncture needle. The percutaneous threaded marrow core bone tumor biopsy puncture needle comprises a threaded biopsy extractor, a cancellous bone way opening needle, a holding handle, an opening forming needle, a pushing rod, a first sleeve and a second sleeve. The cancellous bone way opening needle and the opening forming needle are both stylets with sharp bottoms. The opening forming needle goes deep into the holding handle, and the opening forming needle and the holding handle are combined into a puncture needle body. According to the percutaneous threaded marrow core bone tumor biopsy puncture needle, a special bone window opening tool is arranged, window opening can be easily conducted on the cortex of a bone and the spongiosa of the bone, the puncture needle can reach a diseased region, and the problem that other puncture needles cannot be used for conducting biopsy in the bone or are used for conducting biopsy in the bone difficultly is solved. If a window formed in sclerotin is too large, the pushing rod of the puncture needle can be used for implanting a bone block back through the first sleeve or the second sleeve, and therefore a bony defect is prevented from being too large. After the puncture needle reaches diseased tissue, threads can be screwed in easily to cut the diseased tissue, the screw-in depth can be decided at will, the screws can be directly taken out after sampling is completed, other devices such as a negative-pressure device is not needed, the diseased tissue is easy to collect, and the damage to peripheral tissue is small.

Description

经皮螺纹髓芯骨肿瘤活检穿刺针 Bone marrow core thread percutaneous puncture needle tumor biopsies

技术领域[0001] 本发明属于医疗器械领域,尤其涉及一种经皮螺纹髓芯骨肿瘤活检穿刺针。 Technical Field [0001] The present invention belongs to the field of medical devices, in particular, it relates to a percutaneous bone screw pith tumor biopsy needle.

背景技述 BACKGROUND TECHNOLOGY said

[0002] 骨肿瘤是发生于骨骼或其附属组织的肿瘤,是临床常见的一种疾病。 [0002] Bone tumors occur in bone tissue of the tumor or its subsidiary, it is a common clinical disease. 术前获取病检材料的唯一途径是活检,因此在确保安全的前提下,尽可能获取较多的标本,这样对提高活检诊断正确率十分重要。 The only way to get pathological examination preoperative biopsy material, and therefore under the premise of ensuring safety, get more specimens as possible, so to improve the diagnostic accuracy of biopsy is very important. 目前骨肿瘤穿刺针主要有意大利GALLINI公司的BiomidTrocar穿刺针,德国Ackeman针等,这类针多为经皮套管针,采用岩芯穿刺活检或负压吸取。 Bone tumor puncture needle main current Italian company BiomidTrocar GALLINI needle, Germany Ackeman needles etc., such as a multi-needle stylet through the leather, using core needle biopsy or vacuum suction. 类似的还有美国Cook公司、德国Angiomed公司的弹抢式活检针等。 There are similar American Cook, Germany Angiomed's bomb grab biopsy needles. 目前骨穿刺活检最大的问题是取得的标本组织太少、片面,无法诊断,甚至误诊,造成活检组织少的主要原因之一是活检穿刺针的组织切取结构为凹槽型,凹槽太小;或倒钩形,不能钩出足够多的病理组织;或者为岩芯穿刺,常常不能完整取出。 The biggest problem is the bone biopsy tissue specimens taken too one-sided, not diagnose or even misdiagnosed, one of the main causes fewer biopsy needle biopsy of tissue is cut a groove-type structure, the groove is too small; or barbed, hook can not be more than enough histopathology; or a piercing core, often can not be removed intact.

[0003] 要穿刺获得更多的病理组织,可以采用较粗的穿刺针获取更多的组织,也可以在最佳穿刺层面多点穿刺。 [0003] To obtain more puncture pathology, thick needle can be used to get more organized, can multi-point puncture in the best puncture level. 但这些方法对组织损伤比较大,取材次数的增多还可能引起出血、感染,增加病人痛苦。 However, these methods are relatively large tissue damage, increase in the number drawn is also likely to cause bleeding, infection, increased patient suffering.

发明内容 SUMMARY

[0004] 本发明的目的在于提供一种经皮螺纹髓芯骨肿瘤活检穿刺针,旨在解决现有的骨肿瘤活检穿刺针存在的提取活检组织太少,需要负压装置配套使用且取样过程对病变组织损伤较大的问题。 [0004] The object of the present invention is to provide a percutaneous bone screw pith tumor biopsy needle, biopsy extraction to solve the problems of the prior bone tumor biopsy needle too, requires the use of negative pressure device and supporting the sampling process diseased tissue injury bigger problem.

[0005] 本发明是这样实现的,一种经皮螺纹髓芯骨肿瘤活检穿刺针包括七个组件:①螺纹活检取出器松质骨开路针;③扶持把手开口针推进杆;⑥第一套筒;⑦第二套筒。 [0005] The present invention is achieved in a sheath core threaded bone marrow tumor biopsy needle comprises seven components by: ① thread extractor cancellous bone biopsy needle open; ③ the needle push rod support handle opening; ⑥ first set cylinder; ⑦ second sleeve. 所述的松质骨开路针和开口针均为尖底针芯;所述的开口针深入到扶持把手中,两者组合形成穿刺针。 The cancellous bone pin and open the bottom opening of the needle are pointed needle core; said opening enabling the hands deep into the needle, the puncture needle is formed a combination of both.

[0006] 进一步,所述的螺纹活检取出器的远端2cm处设置有深螺纹,平底。 [0006] Further, the distal end of the extractor screw biopsies provided at 2cm deep threads, flat.

[0007] 本发明的经皮螺纹髓芯骨肿瘤活检穿刺针配备有专门的开骨窗工具,可以轻松的将骨皮质和松质开窗,到达病变部位。 Bone marrow core thread percutaneous puncture needle tumor biopsies [0007] The present invention is equipped with a special tool to open bone window, you can easily be cancellous and cortical bone window, reach the lesion. 解决了其它穿刺针不能或难以做骨内活检的难题,如果骨质开窗太大,可以使用该装置的推进杆经第一套筒或第二套筒将骨块回植上去,避免骨质缺损太大;到达病变组织后螺纹可以轻松的旋进并切割病变组织,旋入深度可以自由决定,取样结束直接取出即可,不需要负压等其它装置,病变组织收集方法简单,对周围组织的损伤小,并且可以同时获得不同深度的病理组织,对肿瘤的分析有重要意义。 Not solve the other needle biopsy or a bone difficult problem, if the window is too big bone, the apparatus can use the pusher sleeve by the first sleeve or the second bone replantation up, to avoid bone defect is too large; precession threads can easily reach the diseased tissue and cut after the lesion, insertion depth can be determined freely, the end of the sample taken directly to another device, no negative pressure, diseased tissue collection simple method, to the surrounding tissue little damage, and pathological tissue can be obtained simultaneously at different depths, it is important for the analysis of the tumor.
