Intelligent collecting system for uterus expanding liquid in hysteroscope operation

Abstract

The invention relates to a collecting device for a uterus expanding liquid, in particular to an intelligent collecting system for a uterus expanding liquid in a hysteroscope operation. The system comprises a collecting membrane in contact with a patient, wherein the collecting membrane guides the uterus expanding liquid flowing out during the operation to the collecting device, and the collectingdevice weighs and displays the collected uterus expanding liquid in real time. The intelligent collecting system for the uterus expanding liquid in the hysteroscope operation has the advantages that the uterus expanding liquid flowing out during the operation can be intelligently monitored through the collecting membrane and the collecting device; in the case of knowing the pumping amount of the uterus expanding liquid, the absorption amount of the uterus expanding liquid can be effectively judged in real time by monitoring the collection amount, the system is conductive to a surgeon's overallgrasp of the patient's condition, the occurrence of TURP is effectively prevented, and the safety of the operation is improved.

Description

technical field [0001] The invention relates to a collection device for uterine distention fluid, in particular to an intelligent collection system for uterine distension fluid in hysteroscopic surgery. Background technique [0002] In endoscopic operations such as gynecological hysteroscopic surgery, ureteroscopic surgery, transurethral resection of the prostate, transurethral resection of bladder tumors and percutaneous nephrolithotomy, in order to maintain a clear surgical field of view, a large number of The flushing fluid washes away the removed tissue, residue, blood or urine in time at a certain speed and pressure and maintains the size of the surgical cavity through pressure. In these endoscopic operations, the flushing fluid is in a flowing state. Under a certain pressure, part of the uterine distention fluid will enter the circulatory system through open blood vessels and venous sinuses. When more flushing fluid enters the blood circulation, it will cause blood dil...

AI Technical Summary

Problems solved by technology

In these endoscopic operations, the flushing fluid is in a flowing state. Under a certain pressure, part of the uterine distention fluid will enter the circulatory system through open blood vessels and venous sinuses. When more flushing fluid enters the blood circulation, it will cause blood dilution, Electrolyte disturbance and circulatory overload are the main features of prostate resection syndrome (TURP, TURP syndrome is currently the main cause of death in hysteroscopic surgery in mainland China), and hyponatremia can cause brain cell edema, nerve excitability The reduction and inhibition of myocardial activity will cause patients to experience unexplained abnormal blood pressure fluctuations, bradycardia, nausea and vomiting, irritability, chest tightness and chest pain and other discomfort symptoms during the operation, although such risks are clearly related to the operation time. However, the operation time alone cannot fully reflect the patient's absorption of the uterine distention fluid, and the specific absorption of the uterine distension fluid is also related to various factors such as the patient himself and the surgical wound. Estimating the specific amount of irrigating fluid absorbed by the patient will make it difficult for the operator to grasp the remaining operation time, and in severe cases, it will also affect the effect of the operation

At present, the uterine distention fluid flowing out during the operation is collected simply by using a collection bucket, and there is no special device to collect the uterine distension fluid, which may cause leakage, resulting in inaccurate collection of the uterine distension fluid, resulting in surgical risks
