Description

一种多功能肾穿刺针 A multi-functional renal biopsy needle

[0001] 【技术领域】 [0001] TECHNICAL FIELD

[0002] 本发明涉及一种肾穿刺针,具体地说本发明涉及一种多功能肾穿刺针。 [0002] The present invention relates to a renal biopsy needle, and more particularly the present invention relates to a multifunctional renal biopsy needle.

[0003] 【背景技术】 [0003] BACKGROUND

[0004] 公知的,肾脏是人体的重要器官,结构复杂,担负多种功能,肾穿刺活体组织检查及病理诊断是当今肾脏病学的一个重要组成成分,是病理学的一个重要分支,是肾脏疾病诊断必不可少的手段;肾穿刺renopuncture即肾活检,也称肾穿刺活检术;肾穿刺活检的开展,可帮助临床医师制定诊疗计划;可以确定移植肾排斥反应的有无、病理类型和严重程度,并对移植肾的急性肾小管坏死、环孢素中毒、复发和再发性肾小球肾炎作出明确的病理诊断;目前临床上大多采用超声引导进行穿刺作业,由于现有的穿刺针结构大多为注射器针头式结构,也就是在管状针头前端制作一个斜面形成针尖;由于管状针头前端的针尖在穿刺时,针尖后部管口的刃面会同步切下皮肉组织并隐藏在针管内,这样不仅给病人带来极大痛苦,而且皮肉组织混杂在肾活体组织中,影响后 [0004] known, kidneys are vital organs of the human body, complex structure, responsible for a variety of functions, biopsy and pathological diagnosis of renal biopsy is an important component of today's nephrology, is an important branch of pathology, kidney an indispensable means of diagnosis; renal needle biopsy that is renopuncture, also known as renal biopsy; to carry out renal biopsy can help clinicians to develop treatment plans; presence or absence of pathology can determine the type of graft rejection and severe degree, and renal transplant acute tubular necrosis, cyclosporine toxicity, recurrence and recurrent glomerulonephritis make a clear pathological diagnosis; currently mostly used ultrasound-guided puncture on clinical work, due to the existing structure of the needle mostly syringe needle structure, i.e. a bevel formed tip of the tubular needle distal production; needle tip of the tubular needle distal end at the time of puncturing, the blade surface of the rear tip of the spout synchronized cut flesh tissue and hidden within the needle, so that not only after the tremendous suffering to the patient, and flesh mixed in kidney tissue biopsy, the impact of 期病理诊断的准确性。 The accuracy of pathological diagnosis period.
