Novel calculus flushing device for urology surgery

Abstract

The invention discloses a novel calculus flushing device for urology surgery, relating to a flushing device, wherein the front end of a liquid storage tube is provided with a tube head, and the tail end is provided with an airbag; a delivery tube is arranged at the front end of the tube head of the liquid storage tube; the delivery tube is movably connected with the tube head at the front end of the liquid storage tube; a flow velocity adjusting groove is positioned on the delivery tube; a flow velocity adjusting valve is arranged in the flow velocity adjusting groove; a long tube is arranged at the front end of the delivery tube; a hose tube is arranged at the front end of the long tube. The novel calculus flushing device disclosed by the invention can greatly improve the efficiency of flushing calculi in a kidney, brings about convenience for patients and medical staff, and has the high practicability; meanwhile, the device is simple in structure and convenient in use.

Description

technical field [0001] The invention relates to a medical flushing device, in particular to a novel calculus flushing device for urology. Background technique [0002] It is well known that kidney stones are common diseases of the urinary system, frequently-occurring diseases, more men than women, mostly in young adults, and there is no significant difference in the incidence rate between the left and right sides. 40% to 75% of patients with kidney stones have different degrees of low back pain. Larger stones with little movement, manifested as soreness and discomfort in the waist, or dull or dull pain when physical activity increases. Colic pain caused by small stones often occurs suddenly with severe pain in the waist and abdomen, which is paroxysmal. [0003] With the development of endourology, minimally invasive percutaneous nephrolithotomy (MPCNL) is gradually applied in clinic. At present, MPCNL is the most effective minimally invasive surgical method for the treatm...

AI Technical Summary

Problems solved by technology

[0004] At present, the flushing of rubble in the kidney is completed through the channel in the ureteroscope, but because the channel of the ureteroscope is relatively long, the diameter of the ureteroscope is small, and the flow rate of the perfusate is small, the flushing force of the flushing fluid is not enough, and the stones in the kidney The efficiency is relatively low, and the time to remove stones from the kidney is too long, and the operation is very inconvenient
