Abstract

The invention relates to the field of medical surgical instruments, in particular to a circulating flushing endoscope sheath which comprises a supporting assembly, a sheath tube, a holding portion and a functional assembly, the supporting assembly comprises a base, a water outlet pipe and a water inlet pipe, liquid enters the base through the water inlet pipe, the discharged liquid is discharged from the water outlet pipe, and the sheath tube comprises a sheath body, a first tube and a switching valve. The sheath body is inserted into a human body during use, the switching valve is used for switching the water inlet and the water outlet, and during normal flushing, the water inlet of the switching valve is opened to be communicated with the first pipe and closed to be connected with the water outlet, so that inlet water can enter the human body through the first pipe for flushing, and then turbid liquid can pass through the sheath body to be used for flushing. After the operation is completed or under the condition of blockage, the water inlet pipe is closed, then the water inlet of the switching valve is closed, and the water outlet is opened, so that the hydrops can be discharged through the water outlet along the first pipe, and the discharge efficiency is improved.

Description

technical field [0001] The invention relates to the field of medical surgical instruments, in particular to a circulating flushing endoscope sheath. Background technique [0002] Speculum sheaths are widely used in medical clinical practice, and there are many types. There is a type of endoscope sheath mainly used in urological transurethral surgery and gynecological transvaginal and cervix endoscope sheaths. Bacterial fluid was used to rinse the surgical area. In the case of complex surgery, easy bleeding, and long operation time, two sheath tubes are needed to flush the liquid from the inner sheath and flow out the liquid from the gap between the outer sheath and the inner sheath to form continuous irrigation. [0003] The channel of the existing single-tube mirror sheath is small when draining liquid, which reduces the efficiency of draining liquid. Contents of the invention [0004] The object of the present invention is to provide a circulating flushing endoscope s...
