As shown in figures 1 and 2, the utility model provides an intracavity vision adjusting and pressure balancing system, which comprises a combined endoscope and an image processing part, wherein the combined endoscope 14 comprises a fiber optic endoscope 15, a multi-cavity tube 16 and a handle 24, the multi-cavity tube 16 is provided with a pressure probe channel 17, an image channel 18, a perfusion channel 19, a drainage channel 20 and an image and perfusion shared channel. The pressure probe channel 17 is internally provided with a pressure monitoring device as a pressure acquisition unit, the pressure monitoring device is a flexible pressure probe with a signal wire, the pressure monitoring device is inserted into the pressure probe channel of the combined endoscope to the front end and is used for detecting the pressure in the cavity and transmitting a detected signal to the control unit.

The handle 24 is fixedly connected with the multi-cavity tube 16, and the wireless transmitting module 23 in the triggering module is arranged on the handle 24; the fiber optic endoscope 15 is inserted into the image channel 18 of the multilumen tubing 16 to assemble a combination endoscope.
The optical fiber endoscope 15 is provided with a light source 11, the light source 11 is connected with an optical fiber endoscope light source interface 21, and light is guided into the cavity through a light guide fiber arranged in the optical fiber endoscope to provide illumination. The image acquisition unit 9 is positioned inside the fiber optic endoscope 15 and is connected with an ocular lens 22 of the fiber optic endoscope, converts the intracavity image observed by the ocular lens 22 into an electric signal to be displayed on the display module 10 and simultaneously transmits the electric signal to the image capture unit.
The image processing part comprises a wireless receiving module 8, an image capturing unit 7, an image preprocessing unit 6, a feature storage unit 4 to be evaluated, a poor visual field feature storage unit 5, a visual field judging unit 2, a pressure acquisition unit 1 and a control unit 2 in a triggering module.
The image capturing unit 7 acquires an intraluminal visual field image by two ways of automatic capturing and manual capturing: in the operation process, an operator feels that a visual field image is fuzzy by observing the image on the display module 10, touches the wireless transmitting module 23 on the handle of the combined endoscope to send an instruction, the wireless receiving module 8 receives the instruction, the image capturing unit 7 starts to capture the visual field fuzzy image from the image acquisition unit 9 and transfers the visual field fuzzy image to the image preprocessing unit 6 for image processing, and after the image processing is finished, an index range of image fuzziness is obtained, the characteristic is stored in the poor visual field characteristic storage unit 5, and meanwhile, the characteristic is sent to the characteristic storage unit 4 to be evaluated; in the operation process, when the wireless transmitting module is not touched, the image capturing unit 7 automatically captures a plurality of images every second, and the images are transferred to the image preprocessing unit 6 for processing, the range of the image fuzziness index obtained after the image processing is finished is obtained, and the characteristics are stored in the characteristic storage unit 4 to be evaluated.
The image preprocessing unit 6 processes the image by:
1) the image processing unit converts the captured image into a gray image after receiving the captured image;
2) acquiring the edge of a gray level image by using an edge detection technology;
3) filtering the marginalized image;
4) and calculating the gray information of the edges before and after filtering, and taking the ratio of the statistical information as the characteristic value of the intra-cavity visual field image.

The characteristic storage unit 4 to be evaluated is used for automatically capturing a plurality of images per second by the image capturing unit in the operation process, and storing the characteristics of the captured images obtained by the image processing unit.
The visual field judging unit 3 compares the features stored in the feature storage unit 4 to be evaluated in real time with all the features in the poor visual field feature storage unit 5, judges that the visual field is fuzzy when recognizing that the features stored in the storage unit to be evaluated after the automatic captured image in a certain period is processed are similar to any one feature in the poor visual field feature storage unit, and feeds back the fuzzy visual field to the control unit 2.
The pressure acquisition unit 1 acquires the pressure detected by the flexible pressure probe in the cavity in real time, and when the detected pressure exceeds a set safe pressure value, the pressure is automatically fed back to the control unit 2.
When the control unit 2 receives the feedback information, the control unit controls the perfusion speed of the perfusion pump 12 and the drainage speed of the negative pressure suction pump 13, for example, when the control unit 2 receives a visual field fuzzy signal fed back by the visual field judging unit 3, the speed of the perfusion pump 12 and the negative pressure suction pump 13 is increased, so that the circulation of liquid in the cavity is increased, the liquid in the cavity becomes clear, the tissue in the cavity can be clearly observed through endoscopic observation, and clear images are transmitted in real time for an operator to observe; when the control unit 2 receives the real-time pressure fed back by the pressure acquisition unit 1 and is close to the set safe pressure value, the perfusion speed of the perfusion pump 12 is reduced, the drainage speed of the negative pressure suction pump 13 is accelerated, so that the pressure in the cavity can quickly reach the set safe pressure value range, the safe pressure is ensured all the time in the operation process, and the operation risk is controlled.
