镜鞘鞘壁上设有出水孔的膀胱肾盂取石镜Bladder pyelonetomy mirror with outlet hole on the wall of mirror sheath

技术领域technical field

本实用新型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。The utility model relates to an apparatus for treating calculi in the body, in particular to a bladder and kidney pelvis stone-taking mirror.

背景技术Background technique

体内结石，如膀胱肾盂结石，是一种常见的疾病。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。Stones in the body, such as bladder and renal pelvis stones, are a common condition. Clinically, intracavitary minimally invasive techniques are often used for lithotripsy of bladder and renal pelvis stones.

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。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。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、摄取碎石和连续冲洗的功能，故临床上已很少使用。At present, the existing bladder lithotripsy adopts the principle of mechanical mechanics, and crushes the stones through the mechanical extrusion of the occlusal force of the lithotripsy forceps. However, it is difficult to crush the stones during operation, and it is also difficult to remove the stones after crushing the stones, and it is easy to damage the bladder and urethral mucosa in the process of crushing the stones. At the same time, the current bladder lithotripsy does not have the functions of fixing stones, providing a channel for crushing stones, flushing crushed stones, ingesting crushed stones, and continuously flushing, so it is rarely used clinically.

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，术中也不能连续冲洗。Various existing ureteroscopes and nephroscopes can provide operation channels for crushing stones by pneumatic ballistic lithotripsy or laser lithotripsy when they are used to treat bladder stones and renal pelvis stones, but there is no effective way to crush the stones after the stones are crushed Take it clean, and do not rinse continuously during the operation.

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。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。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。Existing various bladder and ureteral foreign body forceps are mainly used for ingesting foreign bodies, and can also be used for intraoperative stone removal. However, due to the defects in the design and structure of bladder and ureteral foreign body forceps, they have a single function and can only ingest smaller foreign bodies and broken stones. It cannot be used for intraoperative fixation of stones, lithotripsy, and lithotripsy, so its use in minimally invasive intracavitary lithotripsy is limited.

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。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。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。When the existing lithotripsy technology is used to treat bladder and renal pelvis stones, the stones cannot be fixed during the operation, and the stones are easy to slide in the bladder and renal pelvis, which brings difficulties to the lithotripsy operation. After the lithotripsy, there is no effective means to remove the stones in time. These problems have seriously affected the curative effect of minimally invasive surgery in the treatment of bladder and renal pelvis stones. Therefore clinically need a kind ofly be used in intracavity minimally invasive lithotripsy and can carry out lithotripsy after bladder, renal pelvis calculus are fixed, after calculus is pulverized, can flush rubble again, absorb the surgical instrument of rubble.
