Description

Accurate gas-liquid collection and sample collection device for operation

Technical Field

The utility model relates to an auxiliary instrument that the operating room was used, in particular to accurate gas-liquid is collected and sample collection system for operation.

Background

In the prior art, transurethral resection of prostate (TURP) is performed endoscopically by means of a camera system, and a doctor cannot look directly at the operation area. In order to keep the operation field clear, the perfusion liquid is continuously used to wash the wound surface in the operation process, the blood stain, urine and other waste liquid generated by the operation are discharged through the continuous flowing of the perfusion liquid, and the operation field clear is kept. However, if the pressure of the perfusate is too high, the flow rate is too fast or the water is not smooth, the perfusate can be absorbed to tissue cells, and serious complications such as hyponatremia and water poisoning can be caused. Therefore, the operation time and the perfusion liquid amount must be strictly controlled, and the perfusion liquid is ensured to be smoothly discharged to prevent the occurrence of the syndrome.

Continuous perfusion is needed in the prostate electrosection (TRP) operation, on one hand, the operation position needs to be kept full, so that the tissue is favorably electrically cut, and on the other hand, the visual field can be kept clear due to circular flushing, so that bleeding points can be clearly seen in the operation process, and the continuous operation is convenient.

Meanwhile, in the prostate operation process, a great amount of electrocautery smoke and unpleasant odor are generated due to the use of high-energy electric cutting tissues, and the smoke and the unpleasant odor escape out of the body along with water flow to pollute the environment of the whole operation room. Therefore, the perfusate, the smoke and the waste gas which are simultaneously discharged in the operation are a gas-liquid mixture, the strong burnt peculiar smell and the smoke remained by the high-energy electrical cutting tissue exist, the gas-liquid also contains urine, blood stain and the like, and the smell is very dirty and smelly.

At present, the TURP operation adopts an open drain pipe, one end of the drain pipe is connected with a water outlet of an electric cutting handle, the other end of the drain pipe directly flows into a common open bucket, and perfusion fluid discharged in the operation is collected in an open mode, but waste gas is completely released in the operation room, the taste of the waste gas cannot be removed, and the waste gas can be scattered and volatilized at will in the operation room, and is dirty and foul; because the discharge pipe is not fixed on the open bucket, the irrigation liquid can flow to the floor to cause water accumulation or be stained on the trouser legs of the operating doctor; greatly influences the air, ground environment and sanitation of an operating room, and also greatly influences the mood of doctors and patients during operation; meanwhile, more waste liquid is generated during operation, and the waste liquid is inconvenient to carry; in addition, the samples of human tissue and pathological specimens (such as tissue fragments and blood clots) discharged during the operation are inconvenient to sample and test, and the pathological specimens generated in the whole operation process cannot be completely collected, which is not favorable for accurately analyzing the etiology and the illness state of the patient.
