The invention discloses a multi-channel catheter, a multi-channel endoscope and a using method of the multi-channel endoscope. The multi-channel catheter comprises a catheter body; at least one variable channel is arranged outside the catheter body; part or all of the catheter body of the variable channel is a soft film; the soft film is soft and foldable; the variable channel is sealed; and however, at least one liquid outlet is formed in the front end of the variable channel, and a liquid inlet is formed in the rear end of the variable channel. The multi-channel endoscope comprises a controlhandle and an endoscope tube connected with the control handle, wherein the endoscope tube is a multi-channel catheter. The variable channel is filled with air or liquid, so that the variable channelexpands to become larger, one more through channel can be added, and the functions of the catheter are added. Moreover, the area of a wound which the catheter enters does not need to be increased when channels are added, so that the catheter is more friendly to patients, and use is safer.
Description
technical field [0001] The invention relates to the field of medical instruments, in particular to a multi-channel catheter, a multi-channel endoscope and a method for using the multi-channel endoscope. Background technique [0002] In the medical field, various pipelines are usually used to establish channels to transport gas and liquid or medical devices, such as urinary catheters, suction tubes, or endoscopes, working channels in the guide sheath. Usually, a single pipe has only one through passage, can only have one passageway in and out, and can only realize one function. When it is necessary to establish multiple channels, it is necessary to insert multiple pipes, and a single channel cannot perform drainage and infusion at the same time, and a single channel gap is required for drainage and infusion, or multiple pipes are inserted for drainage and infusion respectively. Therefore, the single-channel pipeline has a single function, and the multi-channel pipeline will ...
