Description

一种推进式输尿管取石装置 A propulsion apparatus of formula ureteral stone

技术领域 FIELD

[0001] 本发明涉及医用器械技术领域,具体涉及一种推进式输尿管取石装置。 [0001] The present invention relates to the technical field of medical instruments, in particular to a device propelled ureteral stone.

背景技术 Background technique

[0002] 输尿管结石为引起肾、输尿管积水以及肾绞痛的主要原因,常继发于肾结石或上端输尿管体外震波碎石术后,结石排出受阻嵌顿于输尿管而引起。 [0002] to cause renal ureteral calculi, and the main reason hydroureter renal colic, often secondary to the upper end of the ureter or kidney stones after extracorporeal shock wave lithotripsy, ureteral obstruction caused by impaction in the stone discharge. 由于输尿管有3个生理性狭窄,且最窄处仅有4_,为结石的产生及形成构建了解剖学基础。 Since there are three physiological ureteral stenosis, and only 4_ narrowest, and is formed to produce stones constructed anatomical basis.

[0003]目前,输尿管结石的主要治疗方法有:体外震波碎石(ESWL),输尿管切开取石及输尿管镜碎石取石术。 [0003] Currently, the main method of treatment of ureteral calculi are: extracorporeal shock wave lithotripsy (ESWL), and ureterolithotomy ureteroscopic lithotripsy. 由于体外震波碎石是在X线定位下进行碎石,对于不含钙的阴性结石显影不佳,无法定位而不能行体外震波碎石治疗,并且针对于与周围组织粘连或嵌顿的结石疗效甚微。 Since extracorporeal shock wave lithotripsy is performed under X-ray positioning gravel, stones for not developing a negative calcium poor, unable to locate not extracorporeal shock wave lithotripsy treatment line, and is directed to the surrounding tissue adhesion and efficacy stones or incarcerated little. 体外震波碎石虽无创,但反复行体外震波碎石则会加重结是与周围组织粘连,而不得不改为开放手术治疗。 Extracorporeal shock wave lithotripsy Although there is no record, but repeated line of extracorporeal shock wave lithotripsy will increase the junction with the surrounding tissue adhesion, and had replaced open surgery. 输尿管镜治疗大多数输尿管结石疗效显著,主要有气压弹道碎石或激光碎石等。 Lithotripsy of ureteral calculi most significant effect, mainly pneumatic lithotripsy or laser lithotripsy and so on. 但现有输尿管镜由于其碎石环境在管腔内且与输尿管壁直接接触,碎石过程中极有可能损伤输尿管,甚者引起输尿管穿孔。 However, because of its conventional lithotripsy ureteroscopy and in direct contact with the environment within the lumen of the ureter, during gravel likely to damage the ureter, ureteral perforation caused worse. 而且对于输尿管内活动度较大的结石,碎石过程中结石还可能被上推至肾盂或进入肾盏,而引起肾脏结石,增大手术难度。 But also for the larger stones ureteral activity, during gravel stones may also be pushed up to the pelvis or into the renal calyx, renal stones cause increased difficulty of operation. 此外,碎石时,结石碎渣对手术视野的干扰亦可影响手术效率,延长手术时间,增加手术风险。 In addition, gravel, stone debris interference with the surgical field may affect the operation efficiency, prolonged operative time, increase the risk of surgery.
