A visual suction tube for high-definition observation with stable image transmission

Abstract

The present invention discloses a visual suction tube for high-definition observation and stable image transmission, which includes a tube body, a notch and a limiting ring formed on the surface of the tube body. The present invention mainly solves two pain points existing in the use process by medical staff. The first is that due to the heat generated by the LED lamp inside the transparent cover, it is easy to cause fogging inside the transparent cover, resulting in unclear imaging. The second is that since there are no more detailed requirements for the angles of the camera and the LED lamp during assembly, the LED lamp is likely to irradiate on the transparent cover and be reflected onto the camera to form a reflection spot. However, this application only needs to adopt a combination form of a closed space, an airbag and an airbag tube, and form air convection by repeatedly inflating gas to remove the water stains on the surface of the transparent cover. At the same time, when inflating gas, it can also prompt the camera to adjust back and forth, and accurately adjust the displacement amount according to the force of the medical staff pressing the airbag, effectively avoiding the formation of spots at the camera.

Description

Technical Field

[0001] The present invention relates to the field of visual suction tubes, and in particular to a visual suction tube for high-definition observation and stable image transmission. Background Art

[0002] Visual suction tubes are mainly used for observing the female uterus. By means of an in-built camera, it can penetrate into the human uterus to understand the lesion area. However, according to the feedback from medical staff, the following problems exist:

[0003] When the LED lighting lamp at the camera is in use, it will emit a large amount of heat. Since there is a small amount of humid air in the transparent cover, a little water stain will form on the inner surface of the transparent cover, resulting in the camera being unable to see the outside through the transparent cover.

[0004] Due to the low requirement for precision during assembly, the light emitted by the LED lamp may be reflected to the camera, forming light spots on the image feedback by the camera, and also making it impossible for the camera to obtain a clear image.

[0005] Therefore, in view of the above problems, a structure is needed to ensure the clarity of imaging.

[0006] For this reason, we propose a visual suction tube for high-definition observation and stable image transmission to solve the above problems. Summary of the Invention

[0007] The purpose of the present invention is to provide a visual suction tube for high-definition observation and stable image transmission to solve the problems raised in the above background art. The technical solution of the present invention provides a solution significantly different from the prior art for the technical problem that the prior art solution is too single.

[0008] To achieve the above purpose, the present invention provides the following technical solutions:

[0009] A visual suction tube for high-definition observation and stable image transmission includes a tube body, a notch and a limit ring opened on the surface of the tube body. One end of the tube body is connected to the limit ring. A camera is slidably connected inside the limit ring. A sealing ring is connected around the camera. A transparent cover is connected to the outer wall of the limit ring. Airbag tubes are connected to the front and back sides of the camera through openings, and the ends of the airbag tubes are connected to airbags.

[0010] In a further embodiment, a handle is provided on the outer wall of the tube body, and the surface of the handle is adhesively connected to the airbag.

[0011] In a further embodiment, the sealing ring, the transparent cover and the camera together form a sealed space, and this sealed space is connected to the airbag through the airbag tube.

[0012] In a further embodiment, a negative pressure interface is connected to one end of the tube body far away from the limiting ring, and the handle is located between the limiting ring and the negative pressure interface of the tube body and is close to the negative pressure interface.

[0013] In a further embodiment, a circuit wiring harness is connected to the back of the camera, and the bottom of the circuit wiring harness and the inner surface of the tube body jointly wrap the airbag tube.

[0014] In a further embodiment, a sliding groove is provided on the inner wall of the limiting ring, and sliding blocks are connected to both sides of the camera and are slidably connected to the sliding groove.

[0015] In a further embodiment, one end of the tube body located at the transparent cover is bent, and the notch is located at the bent section of the tube body.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] The present invention mainly solves two pain points existing in the use process of medical staff. The first is that due to the heat generated by the LED lamp on the inner side of the transparent cover, it is easy to cause fogging on the inner side of the transparent cover, resulting in unclear imaging. The second is that since there are no more detailed requirements for the angles of the camera and the LED lamp during assembly, the LED lamp is prone to irradiate on the transparent cover and reflect onto the camera to form reflection light spots. However, in this application, only a combination form of a closed space, an airbag, and an airbag tube is adopted. By repeatedly inflating gas to form air convection, the water stains on the surface of the transparent cover are removed. At the same time, when inflating gas, it can also prompt the camera to move back and forth, and the moving amplitude of the camera is adjusted according to the force applied by the medical staff pressing the airbag, effectively avoiding the formation of light spots at the camera.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1: Please refer to Figures 1-4 , in the embodiment of the present invention, a visible suction tube for high-definition observation and stable image transmission includes a tube body 1, a notch 2 opened on the surface of the tube body 1, and a limit ring 3. One end of the tube body 1 is connected to the limit ring 3. A camera 4 is slidably connected inside the limit ring 3. A sealing ring 6 is connected to the periphery of the camera 4. A transparent cover 7 is connected to the outer wall of the limit ring 3. Airbag tubes 5 are connected to the front and rear sides of the camera 4 through openings. The opening positions are located at the housing of the camera 4 and do not pass through the circuit board part, so it will not affect the normal operation of the camera 4.

[0027] The end of the airbag tube 5 is connected to an airbag 8. A handle is provided on the outer wall of the tube body 1, and the surface of the handle is adhesively connected to the airbag 8. The airbag 8 on the outside of the handle facilitates medical staff to press and trigger the airbag 8 at any time when holding it.

[0028] One end of the tube body 1 away from the limiting ring 3 is connected to a negative pressure interface 9. The handle is located between the limiting ring 3 and the negative pressure interface 9 of the tube body 1 and is close to the negative pressure interface 9. The negative pressure interface 9 is connected to a negative pressure pump through a pipeline, and the liquid in the uterus is adsorbed through the notch 2 at one end of the tube body 1 to avoid affecting the observation of the camera 4.

[0029] The back of the camera 4 is connected with a circuit cable. The bottom of the circuit cable and the inner surface of the tube body 1 jointly wrap the airbag tube 5. The circuit cable plays a role in transmitting image data outward, and an insulating coating is provided on the surface of the circuit cable. The circuit cable can also cover the airbag tube 5.

[0030] A chute 301 is provided on the inner wall of the limiting ring 3. Sliders are provided on both sides of the camera 4 and are slidably connected to the chute 301. The camera 4 can slide back and forth on the chute 301. The distance of the backward displacement of the camera 4 is controlled by injecting air into the airbag 8, so as to adjust the irradiation angle of the LED lamp on the transparent cover 7.

[0031] One end of the tube body 1 located at the transparent cover 7 is bent, and the notch 2 is located at the bent section of the tube body 1. The bent section of the tube body 1 fits the human body better, and the notch 2 on the surface of the tube body 1 facilitates the negative pressure adsorption of the liquid in the uterus.

[0032] Embodiment 2: Please refer to Figures 1-4 , which is different from Embodiment 1 in that: the sealing ring 6, the transparent cover 7 and the camera 4 jointly form a sealed space, and this sealed space is connected to the airbag 8 through the airbag tube 5. The airbag 8 squeezes the gas into the sealed space through the airbag tube 5 by pressing. When the airbag 8 is released, the gas in the sealed space will flow back under the reverse suction action of the airbag 8.

[0033] The working principle of the present invention is:

[0034] Medical staff hold the part of the handle of the visual suction tube and insert the camera 4 forward into the uterus of the human body. At the same time, turn on the LED lights on both sides of the camera 4 of the visual suction tube to provide illumination for the camera 4 part. When the LED lights are illuminated, the heat generated will be relatively large. Due to a small amount of humid air remaining in the transparent cover 7 during the assembly process, the heat generated by the LED lights will cause water stains in a regional shape on the inner surface of the transparent cover 7, affecting the observation. At this time, the medical staff only need to continuously press the airbag 8 manually, so that the gas in the airbag 8 is quickly input into the sealed space jointly formed by the sealing ring 6, the transparent cover 7 and the camera 4 through the airbag tube 5, and then quickly release the airbag. Repeating this way can achieve rapid air convection, eliminate the fog, accelerate the evaporation of the water stains through the way of air flow, and as the patient's body temperature is gradually transmitted to the outer surface of the transparent cover 7, the fog will gradually disappear.

[0035] When the LED lights are illuminating, due to factors such as the angle, the light will form reflections on the transparent cover 7, and the reflections on the camera 4 will form light spots, which will also cause the situation that the camera 4 is not clear. At this time, the medical staff can apply different pressing forces to the airbag 8. The greater the pressing force, the more gas will rush into the sealed space formed by the transparent cover 7 and the sealing ring 6. At this time, the camera 4 will slide backward on the basis of the sliding groove 301 under the extrusion of the gas, avoiding the light spots and adjusting the reflection angle to make the image clearer. When the airbag 8 is released, the gas in the sealed space will be drawn into the inner side of the airbag 8 through the airbag tube 5, so as to be able to pull the camera 4 in the reverse direction to help it reset;

[0036] This instrument can only be used once. After use, all of it should be uniformly treated as medical waste;

[0037] The material of the transparent cover 7 can be glass or a transparent material with good light transmittance, such as PMMA, etc.
