Description

Technical Field

[0001] The present application relates to the technical field of stone flushing, and more specifically, to a urology stone flushing device. Background Art

[0002] Kidney stones are a common disease of the urinary system, more common in male patients. Once kidney stones occur, it will cause severe colic in patients. During surgical treatment of patients, the urinary system of the patient needs to be flushed and disinfected through the ureter. Usually, a stone flushing device is needed for flushing. The existing public technology number is CN215386423U, which proposes a urological stone flushing device. The device is provided with a push rod, and the angle of the push rod can be limited under the action of the arc groove and the stop block. When the push plate is located at the bottom end of the liquid storage cylinder, the push rod can be rotated to drive the sealing block to open the leakage hole, thereby avoiding the resistance of negative pressure to the reset of the push plate, facilitating the reset of the push plate and facilitating operation. , can provide sufficient flushing liquid, improve flushing efficiency, set sensitive spring and baffle, so that the flushing liquid will not flow back from the liquid outlet nozzle into the delivery tube, improve the cleanliness of the inside of the delivery tube, enhance the flushing effect of stones, but when in use, compared with the flushing device in the literature, the structure is relatively complex, the production cost is high, the use process is complicated, and it brings a strong labor rate to medical staff. After the cleaning liquid is pushed into the liquid storage cylinder, the fluid replenishment work is cumbersome and inconvenient to use. Moreover, the cleaning liquid used for flushing is located in the patient's urinary system and is difficult to empty, that is, the new and old cleaning liquid flow channels cannot be separated, which brings inconvenience to subsequent cleaning and maintenance work. In view of this, we propose a urology stone flushing device. Utility Model Content

The technical problem is that the medical staff can hold the handle and manually press the pressure plate to make the guide rod drive the piston plate to push along the liquid storage cylinder, and the urethra can be cleaned through the flushing tube, and the new and old flow channels of the cleaning liquid can be separated, which effectively avoids the cleaning liquid in the urethra from flowing back into the liquid storage cylinder to contaminate the new cleaning liquid. Because the ventilation valve and the liquid replenishment valve are fixedly connected on the liquid storage cylinder, the negative pressure problem caused by the loss of cleaning liquid in the liquid storage cylinder is avoided, and the medical staff can use it more conveniently. In addition, the liquid storage cylinder is provided with a liquid replenishment valve to facilitate liquid replenishment.
