Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a manual washing device for an endoscope. Background Art

[0002] Endoscopic surgery in hospitals is becoming more and more popular, including transurethral resection of the prostate, transurethral resection of bladder tumors, percutaneous nephroscopic surgery, ureteroscopy and gynecological hysteroscopy. During these surgeries, doctors must clean the surgical site with special fluids through tubes.

[0003] At present, the common practice is to flush the infusion bottle and flush with a large syringe. In the case of flushing with an infusion bottle, the flushing liquid is put into the infusion bottle and hung on the infusion stand beside the bed. The bottle is about 1 meter high from the patient. The liquid medicine enters the bladder through the pipeline for flushing. This flushing method has low pressure and is not clean enough. Flushing with a large syringe has a suitable pressure, but it cannot be flushed continuously. It can only be done intermittently, which is laborious and time-consuming. Each flushing requires extracting liquid medicine, injecting and flushing once, then extracting liquid medicine, and then injecting and flushing again, which is very inconvenient.

[0004] In addition, during the treatment of ureteroscopic lithotripsy, ureteronephrolithotomy and percutaneous nephrolithotomy, a large amount of saline will be injected into the surgical field to ensure a clear field of vision and, when necessary, to irrigate and crush the stones, causing a significant increase in the renal pelvic pressure. At this time, multiple components such as renal pelvic fluid, bacteria, and endotoxins will reversely osmose back into the renal capillaries and bile ducts. When a large amount of bacteria and endotoxins enter the body, fever and infection will occur, and in severe cases, sepsis will occur, and even endanger life. Therefore, in clinical surgical treatment, how to know the internal pressure of the human body in real time and achieve reasonable artificial hydronephrosis while fully irrigating is what doctors always pay attention to.
