Description

膀胱肾盂取石镜 Bladder stone mirror renal pelvis

技术领域 FIELD

[0001] 本发明涉及一种治疗体内结石的器械,具体涉及一种膀胱肾盂取石镜。 [0001] The present invention relates to a method of treating the instrument body calculus, renal pelvis particularly relates to a bladder stone mirror. 背景技术 Background technique

[0002] 体内结石,如膀胱肾盂结石,是一种常见的疾病。 [0002] vivo stones, renal pelvis such as bladder stones, is a common disease. 临床上多采用腔内微创技术进行膀胱、肾盂结石的碎石治疗。 Multi-cavity using minimally invasive techniques bladder, pelvic stones gravel clinical treatment.

[0003] 目前,现有膀胱碎石镜采用机械力学原理,通过碎石钳咬合力的机械挤压将结石粉碎。 [0003] Currently, conventional gravel bladder mirror using mechanical mechanics, gravel jaw bite force by mechanically extruding the crushed stone. 但是由于操作时很难将结石粉碎,结石粉碎后也很难将碎石取净,并且在粉碎结石的过程中容易损伤膀胱、尿道黏膜。 However, due to the difficult operation of crushed stone, crushed stones is difficult to take the net gravel, crushed stones and easily damaged during bladder, urethral mucosa. 同时,目前的膀胱碎石镜也不具有固定结石、提供碎石通道、冲吸碎石、摄取碎石的功能,故临床上已很少使用。 Meanwhile, the current mirror does not have a fixed bladder gravel stones, gravel provide channel impulse absorbing macadam, gravel uptake function, it is rarely used clinically.

[0004] 现有的各种输尿管镜和肾镜在用于治疗膀胱结石和肾盂结石时,可为气压弹道碎石技术或激光碎石技术粉碎结石提供操作通道,但是结石粉碎后却缺乏有效方法将碎石取净。 [0004] The various existing in ureteroscopy and nephroscopy used to treat bladder stones and renal pelvis stones, provides operating channels pneumatic lithotripsy technique or laser lithotripsy stone grinding, but the grinding stone, but the lack of effective methods take the gravel net.

[0005] 现有的各种膀胱、输尿管异物钳主要用于摄取异物,也可用于术中取石。 [0005] Various conventional bladder, ureter forceps mainly for foreign body ingestion, may also be used intraoperatively stone. 但是由于膀胱、输尿管异物钳设计结构上的缺陷,作用单一,只能摄取体积较小的异物和碎石。 However, due to defects in the bladder, ureter forceps design structure, functions as a single, smaller volume ingested only foreign matter and debris. 不能用于术中固定结石,不能进行碎石操作,不能冲吸碎石,因此在腔内微创碎石手术中使用有限。 Can not be used intraoperatively fixed stones, gravel can not operate, withdrawing not be washed gravel, the use of limited Endovascular lithotripsy procedure.

[0006] 采用现有的碎石技术治疗膀胱、肾盂结石时,术中无法固定结石,结石容易在膀胱、肾盂内滑动,给碎石操作带来困难,碎石后又缺乏有效手段将碎石及时取出。 [0006] The conventional lithotripsy treatment of bladder, pelvic stones, stones can not be fixed surgery, bladder stones easily, sliding pelvis, difficult to operate gravel, crushed gravel and then the lack of effective means to promptly removed. 这些问题严重影响了腔内微创手术治疗膀胱、肾盂结石的疗效。 These problems seriously affected minimally invasive endovascular surgery, bladder efficacy of renal pelvis stones. 因此临床上需要一种用于腔内微创碎石术中能将膀胱、肾盂结石固定后再进行碎石,结石粉碎后又能冲吸碎石,摄取碎石的手术器械。 Therefore a need for clinical capable bladder, pelvic stones after lithotripsy fixed Endovascular lithotripsy, crushed stone can suck red gravel, gravel uptake surgical instrument.
