Abstract
The utility model provides a percutaneous kidney channel sheath which comprises an outer sheath, wherein the outer sheath comprises a rod (1) of the outer sheath, a joint (2) of the outer sheath and a water valve (3) of the outer sheath, the three ends of the joint (2) of the outer sheath are provided with openings, the position of an opening at the lower end of the joint (2) of the outer sheath is connected with the rod (1) of the outer sheath, the position of an opening at the side end of the joint (2) of the outer sheath is connected with the water valve (3) of the outer sheath, and the end of the rod (1) of the outer sheath is also provided with a side hole. The percutaneous kidney channel sheath can be repeatedly used and also aims at the defect of a traditional single cylindrical shape. By redesign, the percutaneous kidney channel sheath has various functions, so that the percutaneous kidney channel sheath can be suitable for the traditional percutaneous nephrolithotomy of a micro channel and a standard channel and the traditional percutaneous nephrolithotomy of a big channel. Moreover, the defect of each operation mode is eliminated.
Description
Technical field
This utility model relates to operating theater instruments, particularly relates to a kind of percutaneous kidney operation path sheath with multiple function.
Background technology
Set up a kind of effective operation method that percutaneous kidney passage is the treatment urologic disease by puncture, expansion and indwelling passage sheath, be widely used in the foundation of skin kidney passage in the PCN rubble lithotomy at present, and the percutaneous kidney drainage of disease such as hydronephrosis due to the urinary tract obstruction.The passage sheath of current use is mainly single cylindric, its material is mainly plastics, its advantage is simply, when carrying out micro channel via-skin kidney mirror rubble lithotomy, the calculus fragment is removed by passage or is gone out by current, and its shortcoming is to recycle current when going out calculus, and renal pelvis is intrinsic pressure too high, and current soak the aseptic list of operation and patient's sterile gown, easily cause infect taking place, and can not rubble and get stone and carry out simultaneously; When carrying out standard channel PCN rubble lithotomy, because the passage sheath is single cylindric, even utilize negative pressure ultrasound to attract rubble in the art, still there is the possibility of soaking into aseptic operation list and operating coat in current in the passage sheath, and because by the water inlet of kidney mirror, when seeking calculus and rubble and get stone, calculus is easily washed away by current, causes operating time to prolong and the possibility of residual stones; In addition because the material major part of passage sheath is disposable medical plastic, tension force is little, and easy deformation is after dilator nephrectasia essence, the passage sheath of plastic material is difficult for keeping somewhere, and because plastic material passage sheath easily causes intraoperative hemorrhage more to kidney essence compressing deficiency; From economy and environmental angle,, increased medical burden and be unfavorable for environmental conservation though disposable passage sheath is easy to use.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of percutaneous kidney passage sheath is provided, this passage sheath is that metal is made, can reuse, and at existing single defective cylindraceous, make it have multiple function through redesign, make it can be fit to existing microchannel and standard channel PCN rubble lithotomy, and the PCN rubble lithotomy of traditional major path, and eliminate the drawback of every kind of modus operandi.
The technical scheme that its technical problem that solves this utility model adopts is: percutaneous kidney passage sheath comprises epitheca, epitheca comprises epitheca bar, epitheca joint and epitheca penstock, epitheca joint three end openings, the lower ending opening place of epitheca joint is connected with the epitheca bar, the side opening part of epitheca joint is connected with the epitheca penstock, and the end of epitheca bar also is provided with side opening.
Further, this passage sheath comprises interior sheath, epitheca and epitheca capping three parts, the size of passage sheath is as the criterion with the epitheca internal diameter, from F14.6, each 2F that increases, up to F36.6, the passage sheath of totally 12 different models, the passage sheath of each model all comprises the interior sheath and the epitheca capping of corresponding bore.
Advantage of the present utility model: serve many purposes, can be fit to existing microchannel, standard channel PCN rubble lithotomy by single with the combination of epitheca, epitheca and epitheca capping and the combination of epitheca and interior sheath, and the PCN rubble lithotomy of traditional major path.Single solved that plastic of conduit sheath expansion back is difficult for keeping somewhere and can not reusable shortcoming with epitheca, the combination of epitheca and epitheca capping and the combination of epitheca and interior sheath have solved in existing microchannel, standard channel and the traditional major path percutaneous nephrolithotomy low pressure and the excessive problem of current in the renal pelvis.Difficult the moving of calculus makes rubble more effective during the epitheca water inlet, and calculus fragment sucking-off synchronously when vacuum suction makes air pressure trajectory and holmium laser lithotripsy has solved rubble and got the problem that can stone effectively carry out simultaneously.
