Description

Technical Field

[0001] The present invention belongs to the technical field of endoscopes, and in particular relates to a high-refresh imaging medical endoscope and a refresh control method. Background Art

[0002] With the continuous development of medical technology, endoscopic technology plays an increasingly important role in clinical diagnosis and treatment.

[0003] Traditional medical endoscopes mainly rely on low frame rate imaging technology. Although this technology can meet basic visual needs, its imaging quality and real-time performance often cannot meet clinical needs in application scenarios such as dynamic observation, fine structure detection, and real-time surgical guidance. In addition, the head end of existing endoscopes is mostly cylindrical. When the endoscope enters the body cavity, the body cavity has a certain degree of elasticity. In some small spaces, the body cavity easily covers the end of the endoscope head, thereby affecting its imaging effect. Summary of the invention

[0004] The present invention aims at solving the problems in the prior art and proposes the following technical solutions:

[0005] A high-brush imaging medical endoscope, comprising a head end, a tail end, a connecting line, an image sensor and an image processing unit, the endoscope further comprising an additional middle end threadedly mounted between the head end and the tail end, the additional middle end comprising a cylindrical middle end body, an outer ring wall of the middle end body is provided with an outer ring groove, a latex film is fixedly connected to the outer ring wall of the middle end body, and the latex film covers the outer ring groove to form a closed annular cavity, and the annular cavity is interconnected with an air inlet pipe;

[0006] The air inlet pipe injects air into the annular cavity to increase the internal air pressure, and the latex membrane expands and deforms to prop up the endoscope observation area outward. The outer ring wall of the middle end body is fixedly connected to a plurality of fixing strips located on the periphery of the latex membrane, and the expanded and deformed latex membrane is constrained by the fixing strips to form a recessed area.

[0007] As a preferred embodiment of the above technical solution, the head end includes a head end body, an aperture and a lens assembly, and the head end of the head end body is provided with a top cover, and the outer diameter of the top cover is larger than the outer diameter of the head end body.

[0008] As a preferred embodiment of the above technical solution, the outer edge of the head end of the top cover is processed with a rounded corner, and the tail end of the top cover is processed with a liquid storage ring groove.

[0009] As a preferred embodiment of the above technical solution, a plurality of gaskets are fixedly sleeved on the outer ring wall of the outer ring groove.

[0010] As a preferred embodiment of the above technical solution, the image sensor adopts a CMOS sensor.

[0011] A refresh control method is applied to the above-mentioned high-refresh imaging medical endoscope, and the refresh control method is:

[0012] The image processing unit is provided with a dynamic refresh control module, which intelligently adjusts the image refresh frequency by real-time monitoring of the image signal strength and motion state;

[0013] When a moving object or a rapidly changing image is detected, the refresh rate is automatically increased to obtain a clear image; otherwise, the refresh rate is reduced to save energy.

[0014] The beneficial effects of the present invention are:

[0015] 1. The air inlet pipe injects air into the annular cavity to increase the internal air pressure. The increased air pressure causes the latex membrane to expand and deform and prop up outward, thereby expanding the area around the affected part, so that the affected part can be better observed. The latex membrane in the present invention is made of elastic rubber material, which can prevent the latex membrane from expanding and damaging the body cavity. Due to the deformation and expansion of the latex membrane, the tissue fluid in the expanded body cavity wall is squeezed and flows. In order to prevent this part of the flowing tissue fluid from flowing to the head end, resulting in blurred lens, the outer ring wall of the middle end main body of the present invention is fixedly connected with a plurality of The fixed strips around the endoscope are used to constrain the expanded and deformed latex film to form a concave area. In this way, the tissue fluid of the expanded body cavity wall will be squeezed and flow to the concave area, reducing the probability of the tissue fluid blocking the lens. At the same time, the head end of the head end body is provided with a top cover, and the tail end of the top cover is processed with a liquid storage ring groove. With the liquid storage ring groove, it can further prevent the tissue fluid from blocking the lens, so that the observation effect is better; in addition, when the endoscope continues to move inward or outward, the formed concave area can act as a "drainage groove", which can effectively prevent the accumulation of tissue fluid and thus affect the observation effect;

[0016] 2. The image sensor uses a CMOS sensor. Compared with traditional CCD sensors, CMOS sensors are small in size, low in power consumption, and can achieve high frame rate and high-resolution imaging. A dynamic refresh control module is set in the image processing unit to intelligently adjust the image refresh frequency by real-time monitoring of image signal strength and motion status; when a moving object or a rapidly changing image is detected, the refresh rate is automatically increased to obtain a clear image; otherwise, the refresh rate is reduced to save energy.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0023] Example

[0024] like Figure 1 , Figure 3 As shown, a high-brush imaging medical endoscope includes a head end 10, a tail end 20, a connecting line 30, an image sensor, and an image processing unit. The first internal thread 111 at the tail end of the head end body 11 and the first external thread 21 at the head end of the tail end 20 are adapted to observe some locations with larger body cavities (such as the gastrointestinal tract), the tail end of the head end 10 and the head end of the tail end 20 can be directly connected to form a conventional endoscope head end, and then used.

[0025] like Figure 4 As shown, when the observed body cavity space is small (such as the urinary system), the endoscope further includes an additional middle end 40 threadedly installed between the head end 10 and the tail end 20, and the additional middle end 40 includes a cylindrical middle end body 41, and the head end and the tail end of the middle end body 41 are respectively provided with a second external thread 411 and a second internal thread 412, and the outer ring wall of the middle end body 41 is provided with an outer ring groove 42, and the outer ring wall of the middle end body 41 is fixedly connected with a latex film 44, and the latex film 44 covers the outer ring groove 42 to form a closed annular cavity, and the annular cavity is interconnected with an air inlet pipe 46;

[0026] When in use, the whole device is first pushed to the affected part, and then the air inlet pipe 46 injects air into the annular cavity to increase the internal air pressure. The increased air pressure causes the latex membrane 44 to expand and deform and prop up outward, thereby expanding the area around the affected part, so that the affected part can be better observed; in the present invention, the latex membrane 44 is made of elastic rubber material, which can prevent the latex membrane 44 from expanding and damaging the body cavity;

[0027] Due to the deformation and expansion of the latex membrane 44, the tissue fluid in the expanded body cavity wall is squeezed and will flow. In order to prevent this part of the flowing tissue fluid from flowing to the head end 10 and causing the lens to be blurred, the outer ring wall of the middle end body 41 of the present invention is fixedly connected with a plurality of fixing strips 45 located at the periphery of the latex membrane 44. The expanded and deformed latex membrane 44 is constrained by the fixing strips 45 to form a recessed area. In this way, the tissue fluid in the expanded body cavity wall is squeezed and will flow to the recessed area, reducing the probability of it blocking the lens. At the same time, the head end of the head end body 11 is provided with a top cover 12, and the tail end of the top cover 12 is processed with a liquid storage ring groove 122. Together with the liquid storage ring groove 122, it can further prevent tissue fluid from blocking the lens, thereby achieving a better observation effect. Furthermore, when the endoscope continues to move inward or outward, the formed recessed area can act as a "drainage trough", which can effectively prevent the accumulation of tissue fluid and thus affect the observation effect.

[0028] like Figure 2 As shown, the head end 10 includes a head end body 11, an aperture 13 and a lens assembly 14, and the outer diameter of the top cover 12 is larger than the outer diameter of the head end body 11. By setting the top cover 12 with a large outer diameter, it is not only convenient to install a larger aperture 13, but the larger aperture 13 can improve the light collection ability and obtain a clearer image in a low light environment.

[0029] The outer edge of the head end of the top cover 12 is processed with a rounded corner 121. By setting the rounded corner 121, when the endoscope is pushed inward, the accumulation of tissue fluid in front of the lens assembly 14 can be avoided, and the outer edge of the head end of the top cover 12 can be avoided from being too sharp to damage the body cavity.

[0030] A plurality of gaskets 43 are fixedly sleeved on the outer ring wall of the outer ring groove 42. By providing the gaskets 43, it is possible to prevent the latex film 44 from excessively fitting the outer ring wall of the outer ring groove 42, thereby preventing the air inlet pipe 46 from injecting air into the annular cavity.

[0031] As a preferred embodiment of the above technical solution, the image sensor adopts a CMOS sensor. Compared with the traditional CCD sensor, the CMOS sensor is small in size, low in power consumption, and can achieve high frame rate and high resolution imaging.

[0032] A refresh control method is applied to the above-mentioned high-refresh imaging medical endoscope. The refresh control method is:

[0033] A dynamic refresh control module is set in the image processing unit to intelligently adjust the image refresh frequency by real-time monitoring of image signal strength and motion status;

[0034] When a moving object or a rapidly changing image is detected, the refresh rate is automatically increased to obtain a clear image; otherwise, the refresh rate is reduced to save energy.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
