The utility model comprises a flushing soft port, a multifunctional channel, a channel with barbs, a sealing ring, a manual flushing ball, a set of automatic circulating water pump, a filtering device and a pressure meter. The device simple structure, easy and simple to handle adopts the heavy-calibre to wash the passageway, and the anti-calculus is returned, but the pressure is surveyed, manual, automatic dual mode washes, and water yield, water pressure all can be adjusted by oneself according to the operation needs, have removed patient postoperative and have failed secondary operation by oneself from the calculus removal, have removed frequent stone of getting from the operation in-process from, shorten the operation time, avoid the operation risk that the operation time is long to cause.

Description

Device for removing stones through ureter soft lens sheath

Technical Field

The utility model relates to the field of medical appliances, in particular to a device for removing stones through a ureteral soft lens sheath.

Background

Urinary calculi are common diseases of urinary surgery, the incidence rate of the urinary calculi accounts for 6% -10% of that of urinary system diseases, and the incidence rate of the urinary calculi has an increasing trend in recent years. Ureteroscope is a relatively advanced instrument of treatment urinary system calculus at present. Compared with a ureteroscope, the ureteroscope has the function of bending and folding the lens, and is suitable for treating stones in the kidney or on the upper section of the ureter. In the past, stones in the kidney are made by adopting percutaneous holmium laser lithotripsy, an incision is needed to be made in the waist of a patient, the kidney is penetrated into the renal pelvis, then the stone is broken, the bleeding risk is greatly increased, the patient is not needed to be cut and the kidney is penetrated by the ureteral soft lens at present, the natural cavity of the patient is directly taken, the natural cavity enters the bladder through the urethra, and then the natural cavity enters the ureter to reach the kidney. But ureteroscope has longer path than percutaneous nephroscope, small space and quite different stone clearing efficiency compared with percutaneous nephroscope.

Disclosure of Invention

The utility model mainly aims at the problem of low stone cleaning efficiency of the traditional ureteral soft lens. In the existing operation mode, the ureteroscope has two modes of automatically discharging or removing broken stones by a patient with the powdered stones through a stone removing basket, but has the disadvantages that: the powdered calculus needs to be discharged by the patient, and partial calculus is deposited under the kidney and cannot be completely discharged; the stone removal by fragmentation is complicated and needs to be repeatedly carried out in and out of the channel.

The utility model designs a device for removing stones through a ureteral soft lens sheath. The device simple structure, easy and simple to handle adopts the heavy-calibre to wash the passageway, and the anti-calculus is returned, but the pressure is surveyed, manual, automatic dual mode washes, and water yield, water pressure all can be adjusted by oneself according to the operation needs, have removed patient postoperative and have failed secondary operation by oneself from the calculus removal, have removed frequent stone of getting from the operation in-process from, shorten the operation time, avoid the operation risk that the operation time is long to cause.

The utility model provides a clear stone device of flexible sheath of ureter includes one washes soft mouth, a multi-functional passageway, a passageway that contains the barb, a seal ring, a manual washing ball, a set of automatic circulating water pump, a filter equipment, a manometer.

The soft mouth is further washed by a biocompatible soft head with the length of 5-8mm, the renal pelvis is not damaged, the soft head and the barb channel can reach the Fr9-Fr13 size according to the ureteroscope sheath, and the space of the perfusion circuit is far larger than that of the perfusion circuit operated under direct vision.

Further, the multifunctional channel can be used as a pressure measuring channel, a zebra guide wire or an ultra-smooth guide wire inlet, a water inlet is automatically flushed, and a standby channel is blocked by a large stone.

The length of the channel containing the barbs is 460mm (for men) and 360mm (for women), the length is the same as that of most ureteroscope sheaths, fr9-Fr13 can be achieved according to the ureteroscope sheaths, the outer wall is a super-smooth coating, the inner wall is provided with a plurality of multi-layer barb villus with a spacing of 3mm, stones can be effectively adsorbed in the flushing process, the small stones are blocked from flowing back to the renal pelvis, and the small stones can directly flow out of the channel when flushing is repeated.

The sealing ring is further used for sealing a ureteroscope sheath and a flushing channel gap, so that the hydraulic pressure and the flow can be adjusted.

Further, the manual flushing ball is made of a disposable semitransparent soft material, so that the discharge condition of stones can be observed.

The automatic circulating water pump further comprises a pump body, a water inlet, a water outlet and a water outlet connecting with the filtering device, and the water pressure and the flow can be adjusted.
