Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an airtight and constant pressure controlled waterproof and poisoning auxiliary device for hysteroscopic surgery. Background technique [0002] At present, in the hysteroscopic operation of the uterus, it is necessary to fill the uterus with water to expand the uterus, and then perform the operation. During the operation, if the internal expansion is not enough, the space of the uterine cavity is small, so the operation cannot be performed, but If the internal pressure is too high, the internal water will flow through the cut blood vessels into the circulatory system and fallopian tubes, and then into the abdominal cavity, which will easily lead to pulmonary edema, which can be serious or even life-threatening. Therefore, it is difficult to control the internal pressure during the operation, and each person's blood pressure is different, and the parts of the uterus undergoing sur...

Problems solved by technology

[0002] At present, in performing hysteroscopic surgery on the uterus, it is necessary to fill the uterus with water to expand the uterus, and then perform the operation. During the operation, if the internal expansion is not enough, the space of the uterine cavity is small, so the operation cannot be performed, but If the internal pressure is too high, the internal water will flow through the cut blood vessels into the circulatory system and fallopian tubes, and then into the abdominal cavity, which will easily lead to pulmonary edema, which can be serious or even life-threatening

Therefore, it is difficult to control the internal pressure during the operation, and each person's blood pressure is different, and the parts of the uterus undergoing surgical resection are different. In the prior art, the pressure inside the uterine cavity cannot be dynamically detected and controlled. In the actual operation process , the outside water keeps a certain flow rate into the uterine cavity, which causes excessive pressure on the cervix
