Waterproof poisoning auxiliary device for hysteroscopic surgery controlled by airtight constant pressure

Abstract

A water-proof poisoning auxiliary device for hysteroscopic surgery controlled by airtight constant pressure, including a surgical sleeve, a waterproof plug, a plug feeder and a sealed closed-mouth forceps. A water pressure sensor is fixed on the outer wall of the upper end of the surgical sleeve. The wire is connected to the water pressure controller, and the water pressure controller controls the solenoid valve through the second waterproof wire. There is a water injection port on the outside of the lower end of the surgical sleeve, a drug injection port on the outer side of the lower end of the surgical sleeve, and a rubber injection port on the inner side of the lower end of the surgical sleeve. , the inner side of the rubber is fixed with an instrument channel that runs through the surgical sleeve, a first water pipe is provided in the water injection port, the first water pipe is connected to the outlet of the solenoid valve, the water inlet of the solenoid valve is connected to the second water pipe, the second water pipe is connected to the water pump, and the plug feeder A placement groove is arranged on the upper plane, a handle groove is arranged at the center of the bottom end of the placement groove, and a connecting channel is arranged at the center of the bottom end of the handle groove.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a water-proof poisoning auxiliary device for hysteroscopic surgery controlled by airtight constant pressure. 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 surgical...

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
