[0039] Inside the endoscope hand-held main body 2, an instrument channel 221 passing through the insertion part 22 is arranged between the instrument port 231 and the instrument interface 212, a water inlet channel 222 passing through the insertion part 22 is arranged between the water inlet port 232 and the water inlet interface 213, a water outlet channel 223 passing through the insertion part 22 is arranged between the water outlet port 233 and the water outlet interface 214, and an imaging channel 224 passing through the insertion part 22 is arranged between the imaging port 234 and the imaging interface 215.
[0040] In the embodiment, the handle body 211 is used for holding by the doctor during operation, although the handle does not directly contact the pathogen, but the doctor may contact the pathogen with the hand during operation, and then bring the pathogen to the handle body 211, so the handle body 211 is also designed as a disposable component of the endoscope, which is directly discarded after use. In a specific embodiment, the handle body 211 can be formed by pressing two relatively shell bodies to form a complete shell body.
[0041] The instrument interface 212 can adopt a standardized luer interface, which is convenient for quick connection and disconnection of various medical instruments. The medical instrument is inserted into the instrument channel 221 through the instrument interface 212, and then reaches the instrument port 231, which is used for medical operation on the part to be examined of the patient during operation.
[0042] The water inlet interface 213 and the water outlet interface 214 are respectively used for connecting the input and output pipelines of the flushing liquid; the flushing liquid is input through the water inlet channel 222, and then flushed out from the water inlet port 232 to flush the operation area; the flushing liquid is extracted from the water outlet port 233 through the water outlet channel 223 to ensure the cleaning of the operation area.
[0043] The imaging interface 215 is used for connecting with the endoscope imaging device 1. The endoscope imaging device 1 is inserted into the imaging channel 224 through the imaging interface 215, and then reaches the imaging port 234.
[0044] The instrument channel 221, the water inlet channel 222, the water outlet channel 223 and the imaging channel 224 are isolated from each other, so as to avoid cross contamination, especially to avoid contamination to the endoscope imaging device 1.
[0045] In one embodiment, the instrument channel 221, the water inlet channel 222, the water outlet channel 223 and the imaging channel 224 are made of flexible material, so as to facilitate bending to adapt to the structure of the endoscope hand-held body. Exemplarily, polyurethane (PU), silicone rubber, polyvinyl chloride (PVC), thermoplastic polyurethane elastomers (TPU), elastomeric copolymers such as ethylene-vinyl acetate copolymer (EVA), thermoplastic polyester elastomer (TPEE) and the like can be used.
[0046] The insertion part 22 described above can be rigid or semi-rigid design, made of high-strength, corrosion-resistant, low-friction coefficient material, for example, can use stainless steel and other metals, to ensure smooth movement in complex internal environment.
[0047] In one embodiment, the tip part 23 and the insertion part 22 are not integrally connected. When assembling the endoscope hand-held body 2, first separate the opposite two side shells of the handle body 211 to facilitate assembly, and then connect one end of the instrument channel 221, the water inlet channel 222, the water outlet channel 223 and the imaging channel 224 to the instrument port 231, the water inlet port 232, the water outlet port 233 and the imaging port 234 of the tip part respectively by bonding or any other feasible way, and then pass the other end of each channel through the insertion part 22 and place it in the instrument interface 212, the water inlet interface 213, the water outlet interface 214 and the imaging interface 215 of the handle part, and then connect the other end to the corresponding interface by bonding or any other feasible way, and finally close the opposite two side shells of the handle body 211 to complete the assembly of the endoscope hand-held body 2.

The in-vivo situation is observed through the display screen of the image processing terminal device 3 connected to the endoscope imaging device 1, while the instrument connected to the instrument channel 221 is operated to perform diagnosis or treatment. The flushing liquid enters the body through the water inlet channel 222 and the water inlet port 232, and removes blood, tissue fragments and the like in the field of view to keep the field of view clear. The used flushing liquid is discharged through the water outlet port 233 and the water outlet channel 223. After the operation is completed, the flushing liquid pipeline is disconnected, and then the endoscope imaging device 1 is removed from the imaging interface 215, and the endoscope imaging device 1 is cleaned and disinfected separately for repeated use next time. The endoscope hand-held body 2 is directly discarded as disposable consumables.
