Lithotripsy device with lithotripsy device

Abstract

The invention discloses a calculus crushing device with a crushing stone suction device. The main points of the technical scheme are that it includes a catheter, a drainage tube is arranged on the catheter, and an introduction part is connected to the rear end of the catheter. The introduction part is provided with an introduction The drainage tube communicates with the catheter, and is connected with a negative pressure drainage machine that generates negative pressure in the drainage tube. The negative pressure drainage machine includes a negative pressure tube and a driving mechanism. A piston is arranged in the negative pressure tube, and the driving mechanism is used to drive The piston moves. The present invention has the following beneficial effects: the catheter is inserted into the ureter, thereby inserted into the renal pelvis or calices, and after the lithotripsy equipment crushes the stone, the driving mechanism drives the piston to move away from the drainage tube, so that negative pressure is generated in the drainage tube, To guide the catheter to suck out the urine with gravel, so that the gravel can be discharged as quickly as possible, so that the patient can recover as soon as possible.

Description

technical field [0001] The present invention relates to a kind of medical equipment, more specifically, it relates to a kind of calculus lithotripsy device with the stone suction device. Background technique [0002] Kidney stones are caused by the abnormal accumulation of crystal substances (such as calcium, oxalic acid, uric acid, cystine, etc.) in the kidneys, and are common diseases in the urinary system. Kidney stones are mostly located in the renal pelvis or calyces when they form, and larger stones compress, rub or cause water accumulation in the renal pelvis or calyces, resulting in distending pain or dull pain. When the pain cannot be relieved by drugs or the diameter of the stone is large, surgical treatment measures, such as transureteroscopic lithotripsy, should be considered. Ureteroscopic lithotripsy is a ureteroscope that enters the ureter from the urethra through the bladder. Under the ureteroscope, pneumatic lithotripsy machines, laser lithotripsy machines,...

AI Technical Summary

Problems solved by technology

After the stones are crushed, it is necessary to drink a lot of water, stone expulsion drugs and appropriate exercise to promote the self-discharge of the broken stone fragments, resulting in low efficiency of stone discharge and easy retention in the body, which is not conducive to the patient's rapid recovery of health
