Abstract
The invention relates to a kidney stone clearing operation sheath with a circulating water system, and aims to shorten operation time and prevent renal plevis internal pressure to be over high or too low, thus keeping a clear visual field; the kidney stone clearing operation sheath is convenient in dismounting; the kidney stone clearing operation sheath comprises an outer sheath (1), an outer sheath close device (6), an inner sheath (2), and a suction joint (3); the outer sheath is in a tubular shape, the head portion is provided with a water outlet, the rear portion is provided with a water inlet valve (4), and the end portion of the outer sheath is connected with the inner sheath (2); one side of the suction joint (3) is provided with a washing joint (5), and a water outgoing and stone path is provided; the head of the outer sheath close device (6) is in a conical form.
Description
Technical field
The present invention relates to the clear stone operation of a kind of kidney sheath, is the clear stone operation of a kind of kidney with circulation sheath.
Technical background
Urological department treatment kidney stone is applied through the clear stone art of the micro-fistulization rubble of skin kidney more at present, first does percutaneous puncture through the clear stone art of the micro-fistulization rubble of skin kidney, then expands puncturing hole, until can update sheath. But, at present, in China's Minimally Invasive Surgery apparatus, only have single tube for the kidney operation sheath through the clear stone art of the micro-fistulization rubble of skin kidney, and through the clear stone art of the micro-fistulization rubble of skin kidney often in conjunction with negative pressure, owing to only having single channel, should intake, water outlet again, should carry out operating theater instruments operation, carry out again vacuum suction, be difficult to ensure that the visual field continues clear, need the time to wait for, calculifragous efficiency is had to certain influence. And rubble process renal plevis internal pressure is too high, easily retrograde infection, causes the complication such as septicopyemia, septicemia. Therefore, design the clear stone operation of a kind of kidney with circulation sheath and avoid above-mentioned situation to occur, there is important clinical meaning.
Summary of the invention
The present invention aims to provide the clear stone operation of a kind of kidney with circulation sheath, and the object of its invention is: in order to shorten operating time, avoid renal plevis internal pressure too high or too low, remain and get a clear view, easy accessibility.
In order to realize foregoing invention object, the clear stone operation of kidney of the present invention sheath, it is made up of epitheca, epitheca obturator, interior sheath, attraction joint. Epitheca profile tubulose, head is with apopore, and rear portion is with water intaking valve, and end is connected with interior sheath. Interior sheath end is connected with attracting joint. Epitheca obturator head becomes coniform.
Described epitheca end and interior sheath are locked with rotary lock structure with conical surface location.
Described epitheca end and epitheca obturator are locked with rotary lock structure with conical surface location.
Described interior sheath sheath end is locked with plug structure with attracting joint conical surface location.

Detailed description of the invention
With reference to Fig. 1 and Fig. 2, the present invention is by epitheca 1, epitheca obturator 6, and interior sheath 2, attracts joint 3 to form. Epitheca obturator 6 inserts in epitheca 1, punctures by after conical surface positioning and locking. After puncture, extract epitheca obturator 6, interior sheath 2 is inserted in epitheca 1, by conical surface positioning and locking. To attract joint 3 to insert in interior sheath 2, by conical surface positioning and locking. Water intaking valve 4 provides intake tunnel, enters in body by epitheca 1 middle external tube front end circular hole. Flush-through connection 5 provides water outlet and goes out calculus passage, discharges by interior sheath tube cavity road 7 in interior sheath 2.
