Detailed implementation manners

[0032] The core of the present invention is to provide an endoscope camera device. The structural design of the endoscope camera device prevents blood from contaminating the camera, enabling the doctor to obtain clear images during the operation and ensuring the smooth progress of the operation.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0034] Please refer to Figure 1 , Figure 1 Schematic diagram of the structure of the endoscope camera device provided by the embodiment of the present invention.

[0035] An endoscope camera device is disclosed in the embodiment of the present invention. The endoscope camera device includes a handle 1, a connecting tube 2, a camera 3, and a jet device.

[0036] Among them, the handle 1 is provided with an imaging module. The imaging module is used to convert the image signal collected by the camera 3 into a visible image and feedback it to the doctor through a display device. The doctor observes the surgical field and performs the operation based on the visible image.

[0037] One end of the connecting pipe 2 is connected to the handle 1. The connecting pipe 2 is used for the cable between the imaging module and the camera 3 and the air injection pipe of the air injection device to pass through. The connecting pipe 2 can be made of flexible bendable material or hard material.

[0038] The camera 3 is arranged at the other end of the connecting pipe 2. The cable of the camera 3 passes through the connecting pipe 2 and is connected to the imaging module. The air injection device includes a nozzle 307, an air injection pipe, an air injection control module 4 and a carbon dioxide gas source. The nozzle 307 is arranged on one side of the camera 3. One or more nozzles 307 can be arranged. In order to ensure the overall cleaning of the lens, it is best to arrange a plurality of nozzles 307 circumferentially. The air outlet of the nozzle 307 faces the lens of the camera 3. The air injection control module 4 is arranged on the handle 1. One end of the air injection pipe is connected to the nozzle 307, and the other end of the air injection pipe passes through the connecting pipe 2 and is connected to the carbon dioxide gas source through the air injection control module 4.

[0039] Compared with the prior art, when the endoscope camera device provided by the embodiment of the present utility model is applied, the air injection pipe continuously sprays carbon dioxide gas through the nozzle, while exhausting the air in the surgical field, preventing blood from contaminating the camera. The air injection control module 4 can adjust the flow rate of the carbon dioxide gas ejected, so as to adjust the purging strength for the camera 3. While the carbon dioxide gas purges the camera 3, carbon dioxide can be injected into the surgical field to exhaust the air. Since carbon dioxide dissolves in blood, compared with air inflation, carbon dioxide inflation can make the patient more comfortable and safe while expanding the space of the surgical field, effectively avoiding discomfort symptoms such as abdominal distension and adverse events such as gas emboli.

[0040] As Figure 2 shown, in the embodiment of the present utility model, the camera 3 includes a mounting base 301, a camera module 302 and a waterproof cap 303. The camera module 302 is arranged on the mounting base 301. The waterproof cap 303 is detachably connected to the mounting base 301. One or more sealing structures are arranged between the waterproof cap 303 and the mounting base 301 to prevent blood from entering. The waterproof cap 303 and the mounting base 301 cooperate to cover the camera module 302 inside. The lens of the camera 3 is arranged on the waterproof cap 303. The nozzle 307 is arranged on the inner side wall of the end of the waterproof cap 303 far from the mounting base 301, and the nozzle 307 and the camera module 302 are respectively located on both sides of the lens of the camera 3, that is, the nozzle 307 is used to purge and clean the outer side of the lens of the camera 3 that is easily contaminated by blood. Since blood is much more viscous than water, a nano-coating can be arranged on the lens of the camera 3 to achieve the hydrophobic effect of the lens of the camera 3, so that blood can be more easily taken away by the air flow and the purging effect is better.

[0041] Further optimizing the above technical solution, as Figure 2As shown in the figure, in the embodiment of the present utility model, a plurality of air nozzles 307 are circumferentially and spacedly arranged on the inner side wall of the waterproof cap 303. A first air passage 304 for connecting with the jet pipe is arranged inside the mounting seat 301. An air distribution ring groove 305 and a plurality of second air passages 306 are arranged inside the waterproof cap 303. One end of the air distribution ring groove 305 is used for communicating with the first air passage 304, and the other end of the air distribution ring groove 305 is respectively communicated with each second air passage 306. The second air passage 306 is communicated with the air nozzle 307. Since the air distribution ring groove 305 is annular, as long as the waterproof cap 303 is assembled in place with the mounting seat 301, the air distribution ring groove 305 can be communicated with the first air passage 304. When the jet control module 4 connects the carbon dioxide gas source with the jet pipe, the gas first enters the first air passage 304 along the jet pipe, then is distributed to each second air passage 306 through the air distribution ring groove 305, and finally is ejected from each air nozzle 307 to blow the lens.

[0042] It can be foreseen that during the blowing process, there may be situations where the air pressure is insufficient or the blowing angle is inappropriate. To solve this problem, in the embodiment of the present utility model, at least one air nozzle 307 is provided with a control valve, and the jet control module 4 is communicatively connected with the control valve. Of course, it is best to provide control valves for all the air nozzles 307. In this way, when the air pressure is insufficient, the opening of the control valve can be reduced or the control valves of some air nozzles 307 can be closed, thereby increasing the blowing force and adjusting the blowing angle to make the blowing effect better.

[0043] To reduce the burden on doctors and enable them to concentrate on the operation, in the embodiment of the present utility model, the above jet device further includes a light transmittance detection module for detecting the light transmittance of the lens of the camera 3. The light transmittance detection module is communicatively connected with the jet control module 4. The jet control module 4 is used to control the opening of the control valve to increase the number of air nozzles 307 for jetting air and / or increase the opening of the control valve at the air nozzle 307 when the light transmittance detection module detects that the light transmittance of the lens of the camera 3 is lower than a preset value, thereby increasing the jet volume.

[0044] To further optimize the above technical solution, the endoscopic imaging device further includes a pan-tilt device. The camera 3 is connected to the connecting pipe 2 through the pan-tilt device. The pan-tilt device includes a first base, a first rotation motor, a second base, a second rotation motor, and a control module 5. Among them, the first base is fixedly connected to the connecting pipe 2, the first rotation motor is arranged on the first base, the second base is arranged at the driving end of the first rotation motor, the second rotation motor is arranged on the second base, the driving end of the second rotation motor is connected to the camera 3, and the rotation axis of the first rotation motor and the rotation axis of the second rotation motor are arranged at an angle. In the embodiment of the present utility model, the rotation axis of the first rotation motor and the rotation axis of the second rotation motor are perpendicular. The control module 5 is communicatively connected with the first rotation motor and the second rotation motor respectively. The control module 5 is arranged on the handle 1, as Figure 1As shown, the control module 5 and the jet control module 4 are integrated. The control module 5 includes two knobs. The forward and reverse rotations of one knob can control the forward or reverse rotation of the first rotating motor, and the forward and reverse rotations of the other knob can control the forward or reverse rotation of the second rotating motor. The jet control module 4 includes a button and a knob. The button is used to control the jet of the jet control module 4, and the knob is used to adjust the opening degree of the control valve. Of course, the functions of the button and the knob can be integrated into a rotary button. When the rotary button is rotated, the opening degree of the control valve is adjusted. When the rotary button is pressed, the jet control module 4 starts to jet.

[0045] Preferably, the pan-tilt device further includes a first housing, a second housing, and a rolling bearing. The first base and the first rotating motor are arranged in the first housing, the second base and the second rotating motor are arranged in the second housing.
