[0049] The endoscope handheld main body 2 includes handle part 21, insertion part 22 and tip part 23, one end of the insertion part 22 is connected with the handle part 21, the other end of the insertion part 22 is connected with the tip part 23;The handle part 21 includes handle body 211 and imaging interface 215, and the imaging interface 215 is opened on the handle body 211;The tip part 23 is provided with imaging port 234;Imaging channel 224 passing through the insertion part 22 is arranged between the imaging port 234 and the imaging interface 215;

[0050] When the endoscope imaging device 1 and the endoscope handheld main body 2 are in the connection state, the cable first end 111 is passed from the imaging interface 215, passes through the imaging channel 224, reaches the position in the tip part 23 and close to the imaging port 234, and the first interface component is connected with the imaging interface 215.

[0051] In the embodiment, the above-mentioned imaging cable 11 is used for transmitting image data and light source signal. The imaging cable 11 has a certain length, is arranged in the first interface component 12, and the first interface component 12 is arranged at a preset distance from the cable first end 111 of the imaging cable 11. The preset distance can be designed according to the front end structure size of the endoscope handheld main body 2 for accommodating the imaging cable 11. Specifically, when the endoscope imaging device 1 and the endoscope handheld main body 2 are installed in place, i.e. the cable first end 111 of the imaging cable 11 is passed into the endoscope handheld main body 2, and the cable first end 111 is close to the front end of the endoscope handheld main body 2, the first interface component 12 is connected with the endoscope handheld main body 2 at this time, the installation of the endoscope imaging device 1 and the endoscope handheld main body 2 is realized, and the position of the cable first end 111 is fixed. By reasonably setting the preset distance of the first interface component 12 from the cable first end 111, the cable first end 111 can be made as close as possible to the part to be examined of the patient, so that the effect of improving the accuracy of examination is realized.

In a specific embodiment, the handle body 211 can be designed by pressing two relatively opposite shells to form a complete shell.

[0055] The imaging interface 215 is used to achieve connection 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.

[0056] The insertion part 22 can be rigid or semi-rigid, made of high-strength, corrosion-resistant, and low-friction materials, such as metal, for example, stainless steel, to ensure smooth movement in a complex internal environment.

[0057] When the doctor uses it, holds the handle part 21, inserts the insertion part 22 and the end part 23 into the patient's body to the target position. The in-vivo situation is observed through the display screen of the image processing terminal device 3 connected with the endoscope imaging device 1. After use, the endoscope imaging device 1 is detached from the imaging interface 215, and the endoscope imaging device 1 is cleaned and disinfected separately for the next reuse.

A water outlet channel 223 passing through the insertion portion 22 is arranged between the water outlet port 233 and the water outlet interface 214.

[0089] In the embodiment, the instrument interface 212 can adopt a standardized Luer interface for quick connection and disconnection of various medical instruments. The medical instrument is extended into the instrument channel 221 through the instrument interface 212, and then reaches the instrument port 231. In operation, the instrument port 231 is extended to perform medical operation on the part of the patient to be examined.

[0090] 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 through the water inlet port 232 to flush the surgical area. The flushing liquid is extracted through the water outlet port 233 by the water outlet channel 223 to ensure the cleanliness of the surgical area.

[0091] 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 of the endoscope imaging device 1.

[0092] In one specific embodiment, the instrument channel 221, the water inlet channel 222, the water outlet channel 223, and the imaging channel 224 are all made of flexible materials, so as to be bent to adapt to the structure of the endoscope hand-held body. For example, polyurethane (PU), silicone rubber, polyvinyl chloride (PVC), thermoplastic polyurethane elastomers (TPU), elastomer copolymers such as ethylene-vinyl acetate copolymer (EVA), thermoplastic polyester elastomer (TPEE), and the like can be used for preparation.

[0093] In one specific embodiment, the tip portion 23 and the insertion portion 22 are not integrally connected. In assembling the endoscope hand-held body 2, the opposite two side shells of the handle body 211 are first separated for assembly. One end of the instrument channel 221, the water inlet channel 222, the water outlet channel 223, and the imaging channel 224 are respectively connected to the instrument port 231, the water inlet port 232, the water outlet port 233, and the imaging port 234 of the tip portion by bonding or any other feasible way. The other end of each channel is respectively passed through the insertion portion 22 and placed in the instrument interface 212, the water inlet interface 213, the water outlet interface 214, and the imaging interface 215 of the handle portion. The other end is connected to the corresponding interface by bonding or any other feasible way. Finally, the opposite two side shells of the handle body 211 are closed to complete the assembly of the endoscope hand-held body 2.

[0094] The doctor uses the handle part 21 to insert the insertion part 22 and the tip part 23 into the patient's body to the target position. The situation in the body is observed through the display screen of the image processing terminal device 3 connected with the endoscope imaging device 1, and the diagnosis or treatment is performed by operating the instrument connected to the instrument channel 221. The flushing liquid enters the body through the water inlet channel 222 and the water inlet 232, and removes the blood, tissue fragments and the like in the field of view to keep the field of view clear. The flushing liquid after use is discharged through the water outlet 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. The endoscope imaging device 1 is cleaned and disinfected separately for the next repeated use. The endoscope hand-held main body 2 is directly discarded as disposable consumables.

[0095] Referring to Figure 5 and Figure 12 In one specific embodiment, the imaging port 234 is provided with a sealing part 235, which is arranged on the outer end surface of the tip part 23 and covers the imaging port 234, and the sealing part 235 is made of transparent material.

[0096] In the embodiment, the sealing part 235 is used to prevent the front end of the endoscope imaging device 1 from being contaminated, while not affecting the imaging quality. Therefore, the transparent material used for the sealing part 235 needs to have high light transmittance, and the preferred materials include but are not limited to optical grade glass and high light transmittance polymers (such as polycarbonate, acrylic resin, etc.). The sealing part 235 can be bonded to the structure of the tip part 23 around the imaging port 234. Alternatively, a low surface tension coating can be further provided on the surface of the sealing part 235 to reduce contamination and facilitate flushing. The thickness of the sealing part 235 ranges from 0.1 mm to 0.5 mm. Within the thickness range of the sealing part 235, the endoscope imaging device 1 can be sufficiently protected without affecting the imaging quality.

[0097] Referring to Figure 6 In one specific embodiment, the insertion part 22 includes a first insertion section 225 and a second insertion section 226 connected with each other, the first insertion section 225 is arranged at one end of the insertion part 22 close to the handle part 21, the second insertion section 226 is arranged at one end of the insertion part 22 close to the tip part 23, and the included angle between the first insertion section 225 and the second insertion section 226 ranges from 15° to 30°.

[0098] In this embodiment, the front end of the insertion part 22 is provided with a curved portion (i.e. the second insertion section 226) for the case of needing to bend or turn to enter a complex cavity for imaging. The above-mentioned included angle range is the acute angle formed by the extension line of the first insertion section 225 and the second insertion section 226. The above-mentioned included angle range can adapt to different examination environments and spatial limitations to bypass the curved structure in the body, such as the intestinal tract, etc., so as to reach the target area for imaging.

[0099] Referring to Figure 6 In one specific embodiment, the tip part 23 is located in the extension direction of the second insertion section 226, and the tip part 23 is smoothly connected with the second insertion section 226. The outer shell of the tip part 23 is in the extension line of the outer shell of the second insertion section 226.

[0100] Referring to Figure 12 In one specific embodiment, it further comprises a protective layer 24, which covers the insertion part 22 and the tip part 23.

[0101] In this embodiment, the protective layer 24 can be made of a flexible and durable plastic, such as polyethylene, polypropylene, polyurethane or other high molecular elastomers, which can reduce the friction with the internal tissue to a certain extent when the insertion part 22 and the tip part 23 are inserted into the human body, and improve the comfort of the patient. The protective layer 24 can be wrapped around the outer periphery of the insertion part 22 and the tip part 23 by adhesion or any other feasible way.

[0102] In one specific embodiment, the wall thickness of the instrument channel 221 is in the range of 0.05mm~0.2mm, and the wall thickness of the imaging channel 224 is in the range of 0.05mm~0.2mm.

[0103] In this embodiment, the above-mentioned wall thickness range of the instrument channel 221 is beneficial to the insertion and removal operation of the instrument, on the one hand, a relatively thin wall thickness is maintained to reduce the overall diameter of the insertion part; at the same time, a certain wall thickness is also needed to provide better structural strength to ensure that the instrument channel will not be damaged by the instrument during use.

[0104] The above-mentioned wall thickness range of the imaging channel 224 is beneficial to the insertion and removal operation of the endoscope imaging device 1, on the one hand, a relatively thin wall thickness is maintained to help reduce the overall diameter of the insertion part; at the same time, a certain wall thickness is also needed to provide better structural strength to ensure that the imaging channel will not be damaged by the endoscope imaging device 1 during use.
