Manual fluid continuous perfusion device used in ureter soft lens operation

Technical Field

The utility model relates to a manual structure of filling indicates a manual fluid that is arranged in ureter soft mirror art to last perfusion device especially.

Background

The kidney stone is a urinary system disease and has the characteristics of common and frequent occurrence, the kidney stone is generally positioned in a renal pelvis or a renal calyx when being formed, and can be discharged into a ureter and a bladder, if proper treatment cannot be timely carried out, inflammation infection is easy to cause, patients are increasingly painful, hydronephrosis, uremia and even canceration can be caused in serious cases, so that timely treatment is needed, and otherwise, the human body is greatly injured.

At present, the treatment method of the kidney stone mainly comprises 1) physical stone removal, 2) extracorporeal shock wave stone breaking, 3) an excision stone extraction operation, 4) percutaneous nephrolithotomy stone extraction, 5) minimally invasive operation and the like. Firstly, the physical calculus removal is to carry out urination and calculus removal through a large amount of drinking water, is only suitable for calculus with small size, and cannot take effect on calculus with large size; secondly, the external shock wave lithotripsy is realized by generating shock waves through an external lithotripsy machine, aiming at stones after the shock waves are focused by the machine, and breaking stones in the body through releasing energy for many times so as to be discharged out of the body along with urine, but the method needs to carefully consider the physical quality of a patient, has more unfavorable situations, possibly causes complications after treatment, and therefore cannot be treated efficiently and properly; secondly, the operation of removing the calculus needs to perform incision and calculus removal on the kidney or partial or total removal of the kidney according to the renal calculus condition of a patient, the operation mode has large trauma, high residual calculus rate and slower postoperative recovery, and can also cause various complications and have more hidden dangers; the percutaneous nephrolithotomy is to establish a channel from skin to kidney at waist, insert nephrolithotomy into kidney through the channel, and use lithotripsy tools such as laser, ultrasound and the like to smash and take out nephrolithotripsy, which is mainly used for treating calculi with the size of more than 2cm at present, but the method has hidden troubles of causing wound, nephrohemorrhage, infectious shock and the like of human body and has high complication incidence rate; the minimally invasive surgery mainly utilizes a thin mirror with the diameter of about 3mm, namely a ureter soft mirror, to be inserted into a ureter through a urethra and a bladder, ureteral calculus or kidney calculus is broken and taken out, natural urinary system cavity of a human body is utilized, no incision is made on the body, the minimally invasive surgery is a pure endoscopic minimally invasive surgery of the urinary surgery, compared with an open excision surgery, ureter endoscopic lithotripsy has the advantages of small damage, light pain, quick recovery and the like, and the minimally invasive surgery is also a treatment method which is popularized and applied at present, has better curative effect and has minimum wound.

In the application process of the ureteroscope minimally invasive surgery, physiological saline is required to be filled into a ureter and a kidney cavity according to needs, so that the ureteroscope can keep clear vision on one hand, and a part of crushed calculus can be washed out on the other hand. The conventional method still has many problems during the normal saline perfusion, the normal saline perfusion is generally carried out by adopting a syringe perfusion or an electric perfusion pump mode, when the syringe perfusion is adopted, the treatment cost is low, but because the capacity of the syringe is limited and the liquid inlet and the liquid outlet of the syringe are at the same position, the normal saline needs to be continuously and manually sucked repeatedly for many times and then is perfused, the method can cause the operation fatigue of medical workers, and the treatment efficiency is relatively reduced; when the electric perfusion pump is adopted, although the intellectualization is adopted to replace the manual operation, the treatment cost is higher, and the burden of a patient is heavier, so that the two injection modes have certain defects at present.
