Liquid collecting device for hysteroscope operation

Technical Field

The invention relates to the technical field related to hysteroscopic surgery, in particular to a liquid collecting device for hysteroscopic surgery.

Background

The gynecological hysteroscope operation needs to infuse five percent of glucose solution or physiological saline into uterus for uterus dilatation, firstly, air between a hysteroscope sheath and an optical lens tube is emptied, the hysteroscope is slowly placed into the hysteroscope for operation, liquid infused into the uterus in the process flows out through the vagina, and the liquid collecting device is used for collecting liquid, and tissue flowing out of the uterus is also required to be collected for inspection after the operation is finished, so that the liquid collecting device for the hysteroscope operation can be used;

in the liquid collecting device for gynecological hysteroscope operation disclosed in publication No. CN210785610U, liquid enters the interior of a liquid collecting bag through a liquid inlet disc and a liquid input pipe, the liquid inlet speed of the liquid inlet disc is regulated by regulating a first valve, the liquid is collected through the liquid collecting bag, and the liquid collecting bag is supported by a device support, the device is stable to place, liquid formed in operation is collected through the liquid inlet disc and enters the interior of the liquid collecting bag, so that the liquid is prevented from polluting the ground and a bed body, cleaning and disinfection are facilitated, the liquid can be separated from tissues through a screen after entering the interior of the device support, manual pick-up is avoided, the working efficiency is high, the liquid is separated from the tissues in the interior of the liquid collecting bag, the influence of contact air on the quality of the tissues is avoided, and the detection accuracy is improved;

in a liquid collecting device for hysteroscopy operation disclosed in publication number CN219021584U, a collecting cylinder is placed in a protective cylinder, a connecting column on a first filter screen is inserted into a sleeve, a fixed cylinder is placed in a supporting ring, then a cover plate is covered in the collecting cylinder, a liquid receiving pipe is placed below an affected part of an operator to receive liquid generated in the operation, the liquid flows to a second filter screen and the first filter screen along the liquid receiving pipe, the liquid is filtered into the collecting cylinder, a transverse column is rotated to enable the second filter screen to rotate to the top, then the transverse column is kept fixed, and then the fixed cylinder is rotated to enable the first filter screen and the second filter screen to rotate, so that the liquid between partial tissues inside the first filter screen and the second filter screen is rotated out;

however, the above solution has the following problems in the use process: when collecting liquid, all directly contact with the lower external portion of patient through the feed liquor dish, then collect liquid, and the feed liquor dish can not fine laminating with the patient, collect inconvenient, cause ground, bed body pollution, be unfavorable for cleaning and disinfecting, and when not using, the feed liquor dish directly exposes outside, and then the time that needs to spend to take longer to clear up in using, and when handling the tissue that drops in the liquid, collect through independent filter screen and can not separate tissue and liquid, still there is a large amount of liquid between the tissue on the filter screen, when taking independent tissue to detect, and need not contain unnecessary liquid, need the manual work to get rid of unnecessary liquid, and then increased work load, be inconvenient for getting rid of unnecessary liquid on the tissue.
