Description

Technical Field

[0001] This invention belongs to the field of endoscopy technology, and particularly relates to a high refresh rate imaging medical endoscope and a refresh control method. Background Technology

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

[0003] Traditional medical endoscopes primarily rely on low-frame-rate imaging technology. While this technology can meet basic visual needs, its imaging quality and real-time performance often fall short of clinical requirements in applications such as dynamic observation, fine structure detection, and real-time surgical guidance. Furthermore, most existing endoscope lenses are cylindrical in shape. When the endoscope enters a body cavity, the cavity's elasticity can cause it to enclose the lens tip in confined spaces, thus affecting imaging performance. Summary of the Invention

[0004] To address the problems in the prior art, the present invention proposes the following technical solution:

[0005] A high refresh rate imaging medical endoscope includes a head end, a tail end, a connecting wire, an image sensor, and an image processing unit. The endoscope also includes an additional middle end threaded between the head end and the tail end. The additional middle end includes a cylindrical middle end body. An outer ring groove is formed on the outer ring wall of the middle end body. A latex membrane is fixedly connected to the outer ring wall of the middle end body, and the latex membrane covers the outer ring groove to form a sealed annular cavity. An air inlet pipe is interconnected with the annular cavity.

[0006] The air inlet pipe injects air into the annular cavity, increasing the internal air pressure. The latex membrane expands and deforms, supporting the endoscope observation area. The outer ring wall of the middle main body is fixedly connected with multiple fixing strips located around the latex membrane. The expanded and deformed latex membrane is constrained by the fixing strips to form a concave 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. 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 top end of the top cover is machined with rounded corners, and the tail end of the top cover is machined 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 is a CMOS sensor.

[0011] A refresh control method, applied to the aforementioned high refresh rate imaging medical endoscope, wherein the refresh control method comprises:

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

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

[0014] The beneficial effects of this invention are as follows:

[0015] 1. Air is injected into the annular cavity through the air inlet pipe, increasing the internal air pressure. This increased pressure causes the latex membrane to expand and deform outward, thus enlarging the area around the affected area and allowing for better observation. In this invention, the latex membrane is made of elastic rubber to prevent it 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 compressed and flows. To prevent this flowing tissue fluid from flowing to the tip and causing lens blur, this invention has multiple components fixedly connected to the outer annular wall of the middle main body, located outside the latex membrane. The expansion and deformation of the latex membrane, constrained by the fixing strip, forms a recessed area. This forces the tissue fluid from the expanded cavity wall to flow into the recessed area, reducing the probability of it clogging the lens. Simultaneously, the head end of the main body is equipped with a top cover, and the tail end of the top cover is machined with a fluid reservoir. This, combined with the fluid reservoir, further prevents tissue fluid from clogging the lens, resulting in better observation. Furthermore, as the endoscope continues to move inward or outward, the resulting recessed area acts as a "drainage channel," effectively preventing the accumulation of tissue fluid and thus avoiding any impact on observation.

[0016] 2. The image sensor uses a CMOS sensor. Compared with traditional CCD sensors, CMOS sensors are smaller, consume less power, and can achieve high frame rates and high-resolution imaging. The image processing unit is equipped with a dynamic refresh control module, which intelligently adjusts the image refresh rate by monitoring the image signal strength and motion status in real time. When a moving object or a rapidly changing image is detected, the refresh rate is automatically increased to obtain a clear image; conversely, the refresh rate is reduced to save energy.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions 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-refresh-rate imaging medical endoscope includes a head end 10, a tail end 20, a connecting wire 30, an image sensor, and an image processing unit. The first internal thread 111 at the tail end of the head end 11 and the first external thread 21 at the head end of the tail end 20 are adapted to each other. When observing some locations with large 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 lens for use.

[0025] like Figure 4 As shown, when the observed body cavity space is small (e.g., the urinary system), the endoscope also includes an additional middle end 40 threaded between the head end 10 and the tail end 20. The additional middle end 40 includes a cylindrical middle end body 41. 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. The outer ring wall of the middle end body 41 is provided with an outer ring groove 42. A latex membrane 44 is fixedly connected to the outer ring wall of the middle end body 41, and the latex membrane 44 covers the outer ring groove 42 to form a closed annular cavity. The annular cavity is interconnected with an air inlet pipe 46.

[0026] When in use, first push the whole thing to the affected area, then the air inlet tube 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 outward, thereby expanding the area around the affected area, so that the affected area can be better observed. In this 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] As the latex membrane 44 deforms and expands, the tissue fluid in the expanded cavity wall is squeezed and flows. To prevent this flowing tissue fluid from flowing to the head end 10 and causing lens blurring, the present invention has multiple fixing strips 45 fixedly connected to the outer ring wall of the middle body 41, located around the latex membrane 44. The expanded and deformed latex membrane 44 is constrained by the fixing strips 45 to form a concave area. In this way, the tissue fluid in the expanded cavity wall is squeezed and flows to the concave area, reducing the probability of it clogging 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 machined with a liquid storage ring groove 122. With the liquid storage ring groove 122, tissue fluid can be further prevented from clogging the lens, resulting in better observation effect. Furthermore, when the endoscope continues to move inward or outward, the formed concave area can act as a "drainage channel", 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 easier to install a larger aperture 13, but the larger aperture 13 can also improve the light-gathering ability, resulting in clearer images even in low-light environments.

[0029] The outer edge of the top end of the top cover 12 is machined with a rounded corner 121. By setting the rounded corner 121, the accumulation of tissue fluid on the front of the lens assembly 14 can be avoided when the endoscope is pushed inward, and the excessive sharpness of the outer edge of the top end of the top cover 12 can also be avoided to prevent damage to the body cavity.

[0030] Multiple gaskets 43 are fixedly fitted on the outer ring wall of the outer ring groove 42. By setting the gaskets 43, the latex film 44 can be prevented from excessively adhering to the outer ring wall of the outer ring groove 42, thereby preventing the air intake 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 traditional CCD sensors, CMOS sensors are smaller in size, consume less power, and can achieve high frame rates and high-resolution imaging.

[0032] A refresh control method is provided, which is applied to the aforementioned high refresh rate imaging medical endoscope. The refresh control method is as follows:

[0033] The image processing unit is equipped with a dynamic refresh control module, which intelligently adjusts the image refresh rate by monitoring the image signal strength and motion status in real time.

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

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
