Description
Technical field
The invention belongs to clinical medicine medical instruments field, relate to a kind of extractor being applicable to pull out double J pipe in males.
Background technology
Double J pipe has another name called ureter rack tube, double pigtail catheter or D-J pipe, applies very extensive in urological surgery.Be applicable in the therapeutic process such as expansion of the Upper urinary tract operation such as renal calculus, ureteral calculus, hydronephrosis, renal transplantation, kidney and ureter benign tumor and lithotrite rubble, stricture of ureter.It can play drainage of urine after implanting ureter, prevent the important function of stricture of ureter and adhesion blocking.The double J pipe of all indwellings all needs to pull out after certain time limit, pull out double J pipe method at present and be mainly cystoscope, but cystoscope operating condition is higher, section office need special Cystoscopy Room, and operating theater instruments, operation table, sterilizing equipment decontaminating apparatus will be equipped with, and the doctor that need operate and nurse.A lot of civilian hospital does not possess special Cystoscopy Room.In addition, for patient, under cystoscope, tube drawing costly.
Summary of the invention
technical problem:the invention provides a kind of construct exquisiteness, easy to operate, reduce double J pipe extractor in cost, convenient and safe males.
technical scheme:double J pipe extractor in males of the present invention, comprise mesh basket, can the pliers of opening and closing, the overcoat flexible pipe of silica gel matter, the inner sleeve flexible pipe of silica gel matter, flexible elasticity seal wire, operating grip and tail end action bars, described pliers is arranged on the front end of overcoat flexible pipe, and link with operating grip, described inner sleeve flexible pipe is nested in overcoat flexible pipe, the back segment of inner sleeve flexible pipe is outside exposed, mesh basket is arranged on the front end of inner sleeve flexible pipe, tail end action bars plug is at the tail end of inner sleeve flexible pipe, described elastic bendable seal wire is arranged in inner sleeve flexible pipe, elastic bendable seal wire one end is connected with the seal wire of mesh basket, the other end is connected with tail end action bars.
Further, in apparatus of the present invention, described overcoat flexible pipe inside middle portion is provided with annular projection, and the front end outer side of described inner sleeve flexible pipe is provided with the rounded tabs corresponding with annular projection, can locate after inner sleeve flexible pipe suction overcoat flexible pipe.
Further, in apparatus of the present invention, described pliers and operating grip are respectively by being pivotally mounted on overcoat flexible pipe, operating grip is connected by bifilar seal wire and controls pliers, the inside edge of described overcoat flexible pipe is provided with duct, and bifilar seal wire is all laid in duct, and wherein external control seal wire one end passes from overcoat flexible pipe front end one aperture, outside pliers, tractive makes it open, and internal control seal wire makes it close in inner tractive pliers; The external control seal wire other end is to arrange around thorny handle wheel shaft counterclockwise, the internal control seal wire other end is to arrange around thorny handle wheel shaft clockwise, during handle abduction, external control seal wire tightens tractive, and internal control seal wire loosens, and pliers is opened, time receiving in handle, internal control seal wire tightens tractive, and external control seal wire loosens, and pliers is drawn in.
Further, in apparatus of the present invention, described pliers is two semi-cylindricals, in cylindric after closing up, the built-in latch of pliers, when entirety is closed up, latch can not touch mesh basket, and when mesh basket is with double J pipe, then pliers can firm grip mesh basket together with seal wire.
Apparatus of the present invention can replace double J pipe in traditional cystoscope gripping males, does not need in Cystoscopy Room operation, can people's complete independently, easy to operate.
In this males, the operating procedure of double J pipe extractor is:
(1) operate identical with cystoscope before operation, allow patient take plain abdominal radiograph, determine double J pipe position, get rid of double J pipe and slip into the medium special circumstances of ureter.
(2) during operation, patient lies low, both legs flexing abduction, and routine disinfection also, after penis of sterilizing, spreads aseptic towel.
(3) pipe extractor is smeared paraffin oil, insert urethra and enter bladder (the similar routine of process plugs in catheter), with reference to 20cm place graduation mark, when seeing that urine flows out from two side handles, continue to enter 3-5cm.
(4), after entering, with two side handle opening clamp, and pipe extractor of drawing back is obstructed to gently drawing, and now pliers is stuck in urethra and bladder joint.
(5) by promoting tail handle, the clamping apparatus of activity is ejected, and promote gently until there is obvious resistance (because there is rubber head end mesh basket front end, can not tissue be injured).
(6) pull tail end handle after fixing inner sleeve flexible pipe, open mesh basket.
(7) a little after left rotation and right rotation mesh basket, tighten up mesh basket, then fix two side handles and to pull back inner sleeve flexible pipe, until obvious resistance.
(8) close pliers and clamp, pipe extractor entirety is taken out.
beneficial effect:compared with prior art, the present invention has the following advantages:
(1) tradition uses cystoscope to pull out patient's double J pipe and need to be equipped with special Cystoscopy Room, and need special doctor, nurse operates, also need a whole set of disinfection apparatus, cystoscope apparatus and display device etc., require higher to operating condition; In addition, the cystoscope operating time is long, needs a whole set of cystoscope to operate, and as mirror of sterilizing, get, anesthesia, slotting mirror, look for double J pipe, tube drawing etc., and centre constantly needs nurse to assist, operating procedure is many, the time is longer.But with after the present invention, can simplify the operation step greatly, medical personnel at more than ten minutes end of operations, can effectively avoid the waste of medical resource, cystoscope are used for the real cystoscopic patient of needs;
(2) traditional cystoscope tube drawing is higher to conditional request, and a lot of civilian hospital there is no cystoscope condition, and thus a lot of needs of patients is gone to a doctor to relative large hospital, and increase large hospital is gone to a doctor pressure;
(3) the present invention is easy to operate, is convenient to popularize, especially basic unit not possess hospital's demand of Cystoscopy Room large;
(4) the present invention constructs exquisiteness, and cost reduces greatly relative to cystoscope, traditional cystoscope tube drawing four or five hundred yuan easily, and uses the cost that The present invention reduces patient.
