Normally-closed suction flusher for endoscopic surgery and using method thereof

Abstract

The invention relates to a normally-closed suction flusher for endoscopic surgery and a using method thereof. According to the invention, an upper cover can rotate relative to a lower cover so as to cover the lower cover or release covering. A Y-shaped hose assembly comprises a straight pipe body, a flushing hose and a suction hose, wherein one end of the straight pipe body is branched to form theflushing hose and the suction hose; a flushing joint is inserted into the end part of the flushing hose, and a suction joint is inserted into the end part of the suction hose; the flushing button assembly is used for controlling communication and closing of the flushing hose and the straight pipe body, when the flushing button assembly is in a normal state, the flushing hose and the straight pipebody are normally closed, and when the flushing button assembly is pushed upwards, the flushing hose and the straight pipe body are communicated; the suction button assembly is used for controlling the suction hose and the straight pipe body to be communicated and closed, when the suction button assembly is in a normal state, the suction hose and the straight pipe body are normally closed, and when the suction button assembly is pushed upwards, the suction hose and the straight pipe body are communicated. The Y-shaped hose assembly is convenient to replace, and medical waste is reduced.

Problems solved by technology

[0002] During laparoscopic surgery, there will be blood or other residual tissues in the surgical area. At this time, it is necessary to use a suction irrigator to wash away the blood and other residues so that the next operation can be carried out smoothly. The existing suction Irrigators are generally divided into two types: disposable and replaceable suction tubes; disposable suction irrigators cannot be replaced because of their flushing tubes. Aspirators, on the one hand, increase the medical expenses of patients, on the other hand, they will generate more medical waste, which is not environmentally friendly; therefore, most hospitals currently advocate the use of suction irrigators with replaceable suction tubes.

[0003] However, due to the unreasonable structural design of the existing suction washer with a replaceable suction pipe, there is a shortcoming that the suction pipe is not easy to replace. One channel of the dual-channel interface is fixedly connected to the suction port with a hose, and the other channel is fixedly connected to the flushing port with a hose. The suction port and the flushing port are respectively snapped into the tail of the handle and fixed with a rear nut, which is inconvenient to disassemble. In addition, The suction button and suction button are installed on the upper side of the handle, and the doctor needs to use the thumb to press the button while holding the handle, which is inconvenient to operate
