The utility model relates to medical instruments, in particular to a ureteral stent, which comprises a tube body and a traction line. The tube body is provided with a drainage hole, a closed end, a J-shaped end, a reinforcing rib, a semi-enclosed cavity and a cavity. The utility model is characterized in that a cross-shaped reinforcing rib is arranged in the inner part of the tube body, and the reinforcing rib divides the tube body into four independent cavities, including three through cavities and one semi-enclosed cavity, and a semi-enclose A drainage hole is arranged on the tube body, which contains two J-ends, one of which is a closed end at the top, and the traction wire is fixed at the J-end without a closed end. The utility model has simple structure. The reinforcing rib structure enhances the strength of the ureteral stent, avoids the flattened outflow caused by the insufficient strength of the ureteral stent in clinical use. At the same time, compared with the traditional product, the through-cavity structure design only passes through. Drainage hole for drainage, its drainage efficiency is higher, greatly reducing the risk of blockage, traction line design facilitates the removal after surgery.
【技术实现步骤摘要】
一种输尿管支架
本技术涉及一种医疗器械,具体说是一种不易扁瘪断流,引流效率高、堵塞风险低的输尿管支架。
技术介绍
我们知道,输尿管支架广泛应用于泌尿系各手术操作中。适用于肾结石、输尿管结石、肾积水、肾移植、肾及输尿管良性肿瘤等上述尿路手术以及碎石机碎石、输尿管狭窄的扩张等的治疗,输尿管支架可有效解除上尿路结石、输尿管水肿造成的暂时性上尿路梗阻,预防术后输尿管狭窄和漏尿的发生,利于患侧肾脏功能恢复。在泌尿系结石微创手术中,通过激光等碎石工具将结石击碎,较大的结石残片可通过水流冲出和套石篮取出,粉末化的结石(<2mm)往往需要术后自行排出,通过置入输尿管支架,结石粉末可沿着支架壁有序排出,输尿管支架的内引流作用保持尿路通畅,因为本身结构设计原因,输尿管支架在使用过程中容易因为输尿管挤压产生扁瘪,进而无法支撑输尿管;输尿管支架上的引流孔易堵塞,造成输尿管堵塞。
技术实现思路
本技术的目的是解决上述现有技术的不足,提供一种不易扁瘪断流,引流效率高、堵塞风险低的输尿管支架。本技术解决上述现有技术的不足所采用的技术方案是:一种输尿管支架,其包括支撑管体和牵引线,其特征在于支撑管体内部设有十字型加强筋,十字型加强筋将支撑管体内部分隔为四个独立的引流腔,四个引流腔的支撑管体侧壁上设有引流孔;支撑管体的两端弯曲、形成J型端,其中一个J型端顶部的支撑管体端部为封闭端,牵引线连接在另一个J型端处。本技术进一步改进,所述的四个引流腔中1-3个引流腔的支撑管体侧壁上沿其纵向设有纵向贯通的引流槽口。引流槽口即为该引流腔的引流孔,不易堵塞、引流效率高。本技术在临床使用时,导丝通过支撑 ...
