Description
Technical field
This utility model relates to medical apparatus technical field, particularly a kind of Urology Surgery ureter stone taking device with shutoff function.
Background technology
Urinary system calculus sickness rate, up to 5%-10%, is found in any position of kidney, ureter, bladder and urethra, with kidney and ureteral calculus the most common.The primary treatments of ureteral calculus has: extracorporeal shock-wave lithotomy (ESWL), urethral smooth muscle and ureteroscope rubble lithotomy.Because ureteroscope rubble lithotomy carries out rubble through human body natural's tract, there is Wicresoft and the definite advantage of rubble.But also there is certain deficiency in current ureteroscope rubble lithotomy: 1. in ureter, epimere calculus and stone debris be easily poured the recoil strength refunds renal pelvis of current or rock breaking tool or enter renal calices, and cause kidney stone, increases operating difficulty; 2. the intraluminal residual calculus chip of ureter lacks mode efficiently and effectively and takes out.
Being blockaded above ureteral calculus by instrument is prevent ureteral calculus by the important means of the kidney that recoils back, also has some ureter stoppers clinically at present, and this type of calculus instrument of stopping also has the function of taking out calculus concurrently under normal circumstances.But still there is certain shortcoming in actual use in these ureter stoppers.
Cover stone indigo plant is that calculus the most frequently used at present stops taking-up instrument, and its rear distraction above leap calculus is netted thus plays the effect preventing calculus chip from upwards drifting about, and meanwhile, cover stone is blue as getting lapicide's tool, and little calculus chip is caught and taken out.But the blue volume of cover stone is comparatively large, is not easy to place, also may promotes calculus and make it be shifted in put procedure; And cover stone indigo plant to get the amount of stone limited at every turn, often need repeatedly to enter mirror, the risk that mirror then can increase Remaining debris drift is entered in water filling repeatedly; In addition, ureter tube chamber can not seal by cover stone indigo plant completely, still there is the probability that calculus is slipped through the net; Moreover the calculus fin in cover stone basket is easily extruded from Lan Kongzhong, and drag when getting stone and easily scratch ureter tube wall, severe patient leads to complications.
Chinese patent literature CN201520227160.X, relates to medical apparatus technical field, particularly relates to a kind of Urology Surgery ureter stone taking device with shutoff function.Comprise the delivery sheath of a hollow, be provided with the inner core sleeve pipe of a hollow in delivery sheath, described delivery sheath front end is connected with basket, and rear end is connected with gripping handle; The front end of described inner core sleeve pipe is provided with a guide head, and rear end is connected with drawing handle; Described basket front end is connected with guide head, and rear end is connected with delivery sheath.This utility model structure is simple, reasonable in design, production cost is low, easy to use, by the plugging film that basket periphery is provided with, intra-ureteral calculus can be placed in closed basket and carry out rubble, and to surrounding tissue not damaged, procedure efficiency and effect can be significantly improved, alleviate misery and the burden of patient.But, although it can utilize plugging film to reach the effect of shutoff, but because plugging film is thinner, and involve great expense, good plugging effect can not be played, and adopt wire netting to make due to basket, may swipe and easily scratch ureter tube wall, and basket expansion is too stiff, is unfavorable for that basket is expanded smoothly.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of Urology Surgery ureter stone taking device with shutoff function, thinner to solve in prior art the above-mentioned plugging film caused, and involve great expense, good plugging effect can not be played, and due to basket adopt wire netting make, may swipe and easily scratch ureter tube wall, and basket expansion is too stiff, is unfavorable for the defect that basket is expanded smoothly.
For achieving the above object, this utility model provides following technical scheme: a kind of Urology Surgery ureter stone taking device with shutoff function, comprise carrier pipe, contiguous block, ball sealer and inflatable ball, be hollow structure in described carrier pipe, inside is provided with connection tube, one end of carrier pipe is provided with hands handle, carrier pipe is fixedly connected with handle, the outside of handle is provided with stretching handle, and one end of connection tube is connected with stretching handle through handle, other one end of connection tube is connected with contiguous block, carrier pipe is provided with trachea branch near one end of handle, trachea branch is connected with inflatable ball, ball sealer is located at the other end of carrier pipe, and ball sealer and carrier pipe connect, the inner side of ball sealer is provided with basket.
Preferably, described basket is the wire netting of metal wire knitted, and be taper shape after expansion, tapering point is fixedly connected with carrier pipe, and round nose is provided with gas tube, and basket is fixedly connected with contiguous block by gas tube, and being connected with carrier pipe of gas tube.
Preferably, the density of described basket tapering point grid is greater than the density of round nose grid.
Preferably, described ball sealer adopts containing the medical balloon of thermoplastic elastomer (TPE).
Preferably, after described ball sealer inflation, shape is semicircle, and radius is greater than the radius of described basket round nose.
The beneficial effect of above technical scheme is adopted to be: it is complete that this utility model reaches shutoff by ball sealer, prevent the defect that Gallstone slide is omitted, disposable object of getting stone, the incidence rate of Incarcerated stone can be reduced again, utilize ball sealer to support ureter tube wall simultaneously, the tinsel of basket can be avoided to scratch ureter tube wall, utilizing outside inflatable ball, handle and the get stone operation of stretching handle to inside control, inflatable ball makes gassy in ball sealer and gas tube, play the effect supporting ureter tube wall and basket, stretching handle control basket open size and angle, handle controls the turnover of whole stone taking device, structure is simple, reasonable in design, production cost is low, easy to use, calculus can not be promoted to drive in the wrong direction back kidney, also not easy damaged ureter tube wall, reduce the friction of rubble and ureter tube wall, procedure efficiency and effect can be significantly improved, obviously alleviate misery and the burden of patient.
