Description

Translated fromChinese
具有安全标识的经皮肾镜导丝Percutaneous nephroscopic guide wire with safety sign

技术领域technical field

本发明涉及医用内窥镜的引导装置,具体是一种具有安全标识的经皮肾镜导丝。The invention relates to a guiding device for a medical endoscope, in particular to a percutaneous nephroscopic guide wire with a safety mark.

背景技术Background technique

经皮肾镜和经皮肾造瘘技术都是在泌尿外科领域内常用的治疗方法。经皮肾镜经常用于治疗肾内大于2厘米肾结石。治疗时首先使用穿刺针从皮肤穿刺到有结石肾盏、肾盂内,然后将一个J型导丝通过穿刺针放置到有结石的肾盏或肾盂内,去除穿刺针,通过导丝使用F8-F24的筋膜扩张器逐渐由细到粗扩张皮肾通道,在皮肤和肾内结石之间建立一个保留经皮肾镜治疗镜鞘的通道,最后通过该通道将结石粉碎并取出。以往该通道的建立是采用X线和B超两种定位和监测方法,X线定位和监测筋膜扩张器逐层扩张的准确性强,不会造成扩张过深或过浅等误损伤发生。但采用X线定位设备昂贵,又会造成病人和医生放射性伤害。所以目前很多医院都采用B超定位的方法,但该方法对于监测筋膜扩张器的扩张深度不准确,医生多是凭借个人的经验和手感来判断筋膜扩张器的扩张深度,有时扩张过深会造成肾脏损伤大出血的并发症,也会由于扩张过浅,重复扩张而导致扩张通道丢失的风险。Both percutaneous nephroscopy and percutaneous nephrostomy techniques are commonly used in the field of urology. Percutaneous nephroscopy is often used to treat kidney stones larger than 2 cm in the kidney. During the treatment, first use a puncture needle to puncture into the renal calyx and renal pelvis with stones from the skin, then place a J-shaped guide wire through the puncture needle into the renal calices or renal pelvis with stones, remove the puncture needle, and use F8-F24 through the guide wire The fascial dilator gradually expands the skin-renal channel from thin to thick, and establishes a channel between the skin and the intrarenal stone to retain the sheath of the percutaneous nephroscopic treatment. Finally, the stone is crushed and taken out through this channel. In the past, the channel was established using X-ray and B-ultrasound positioning and monitoring methods. The accuracy of X-ray positioning and monitoring of the layer-by-layer expansion of the fascial expander will not cause accidental damage such as too deep or too shallow expansion. However, X-ray positioning equipment is expensive, and it will cause radiation damage to patients and doctors. Therefore, many hospitals currently use the B-ultrasound positioning method, but this method is not accurate for monitoring the expansion depth of the fascial expander. Doctors mostly rely on personal experience and hand feeling to judge the expansion depth of the fascial expander, and sometimes the expansion is too deep. It will cause complications of kidney damage and massive hemorrhage, as well as the risk of loss of the expansion channel due to shallow expansion and repeated expansion.

目前市售的经皮肾镜导丝由不锈钢导丝制成,包括芯丝和外层的绕丝弹簧,导丝的末端呈“J”形。此类导丝分有三种不同构造,1.不锈钢J型导丝,仅在导丝的末端5厘米左右的长度带有外层的绕丝弹簧。2.带有PTFE涂层的J型导丝,包括芯丝和外层的绕丝弹簧,但在导丝的表面带有PTFE涂层的J型导丝,涂层的作用是可以增加导丝的光滑度。3.非全涂层PTFE的J型导丝,在带有PTFE涂层的J型导丝末端有5-7厘米距离里的绕丝弹簧没有PTFE涂层,该款导丝的设计是为了在使用筋膜扩张器的时候增加末端的摩擦力和手感。The current commercially available percutaneous nephroscopic guide wire is made of stainless steel guide wire, including a core wire and an outer coiled wire spring, and the end of the guide wire is in a "J" shape. This type of guide wire has three different structures. 1. The stainless steel J-shaped guide wire has an outer layer of wire-wrapped spring only at the end of the guide wire about 5 cm in length. 2. The J-type guide wire with PTFE coating, including the core wire and the outer wire spring, but the J-type guide wire with PTFE coating on the surface of the guide wire, the function of the coating is to increase the guide wire smoothness. 3. J-type guide wire with non-full coating PTFE. There is no PTFE coating in the wire spring at the end of the J-type guide wire with PTFE coating at a distance of 5-7 cm. Increase the friction and feel of the end when using the fascial expander.

中国专利CN 2683042 Y公开了“一种带有刻度的穿刺针针头”,其是在普通穿刺针头的基础上,增加了刻度标记。从针尖处始作为“0”刻度的起点,且不同长度单位的的刻度用不同的颜色及不同长短来表示,解决了现有穿刺针头因没有刻度,在穿刺过程中仅凭操作者的估计而缺乏精确度的问题,从而使穿刺操作更加数字化、准确化。Chinese patent CN 2683042 Y discloses "a puncture needle with a scale", which is based on an ordinary puncture needle with a scale mark added. The starting point of the "0" scale starts from the needle tip, and the scales of different length units are represented by different colors and different lengths. The problem of lack of precision makes the puncture operation more digital and accurate.
