Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to an endoscope system. Background Art

[0002] An endoscope is a detection instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. It usually has an image sensor, optical lens, light source, mechanical device, etc. It can enter the stomach through the mouth or enter the body through other natural orifices. The endoscope can be used to see lesions that cannot be displayed by X-rays, so it plays a very useful auxiliary role in the doctor's treatment activities.

[0003] However, in order to accurately observe the images of the lesion site, traditional endoscopes need to use radiation and contrast agents to be delivered into the patient's body, which poses a risk of kidney damage and radiation exposure, and has problems such as low treatment reliability, poor results, and great safety hazards. Summary of the invention

[0004] Based on this, it is necessary to provide an endoscope system to address the problems of low treatment reliability and potential safety hazards.

[0005] The present application proposes an endoscope system, which comprises:

[0007] a supporting tube, one end of which is connected to one end of the operating handle, and a tube cavity of the supporting tube is communicated with the installation cavity; and

[0008] A camera is mounted on an end of the supporting tube away from the operating handle, and the camera is electrically connected to the image processing chip.

When in use, the carrier tube is inserted into the body through the hole or opening on the patient's body and delivered to the lesion site. At this time, the camera preset at the end of the carrier tube can face the lesion site, and then can directly capture the real-time image of the lesion site. The acquired image data is transmitted to the image processing chip, and after pre-processing, it is transmitted to the external in vitro display through a shielded wire. In this way, the doctor can observe the image of the lesion site on the in vitro display in real time, so as to effectively grasp the lesion condition of the lesion site, perform auxiliary surgery, etc. Compared with the existing technology, it can also abandon the use of radiation and contrast agents, eliminate the risks and hidden dangers of kidney damage and radiation exposure, and improve the safety and reliability of treatment.

[0017] In one embodiment, the endoscope system further comprises a snake-bone structure, wherein the snake-bone structure is mounted at an end of the supporting tube away from the operating handle, and an outer surface of the snake-bone structure is coated with a hydrophilic coating.

[0018] In one embodiment, the endoscope system also includes a bending control mechanism, which is movably mounted on the operating handle and is drivingly connected to the snake-bone structure to drive the snake-bone structure to bend so as to change the shooting angle of the camera.

[0019] In one embodiment, the bending control mechanism includes a rotating wheel, a first traction member, a second traction member and a handle member. The rotating wheel is rotatably arranged on the operating handle, one end of the first traction member is wrapped around the rotating wheel, and the other end of the first traction member is used to connect to one side of the snake-bone structure, one end of the second traction member is wrapped around the rotating wheel, and the other end of the second traction member is connected to the other side of the snake-bone structure, and the handle member is fixed to the rotating wheel to drive the rotating wheel to rotate in both directions.

If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0037] See also Figure 1 and Figure 2 , is an endoscope system 100 shown in one embodiment of the present application, which includes an operating handle 10, a supporting tube 30 and a camera 40.

[0038] The operating handle 10 is the main structural component of the endoscope system 100 , and serves to load functional components such as the integrated support tube 30 and the camera 40 , while facilitating the doctor to hold the endoscope system 100 during use.

[0039] The operating handle 10 has a contoured design that fits the curled palm well, thereby improving the comfort and experience of holding.

[0040] The operating handle 10 can be made of any one of plastic, metal, composite material, etc., and can be flexibly selected according to actual needs.

[0041] Please continue reading Figure 3 and Figure 4 An installation cavity is formed inside the operating handle 10, and an image processing chip is arranged in the installation cavity. The image processing chip is electrically connected to a shielded wire 20, and one end of the shielded wire 20 away from the image processing chip extends to the outside of the operating handle 10; one end of the supporting tube 30 is connected to one end of the operating handle 10, and the tube cavity of the supporting tube 30 is connected to the installation cavity; the camera 40 is installed at the end of the supporting tube 30 away from the operating handle 10, and the camera 40 is electrically connected to the image processing chip.

[0042] Furthermore, compared with ordinary wires, the shielded wire 20 is covered with a shielding structure layer on the outside, which can form a shielding effect against electromagnetic interference in the external environment, thereby ensuring the accuracy of image transmission.

[0043] One end of the shielded wire 20 extending outside the operating handle 10 is connected to a pluggable interface 20a, such as a medical-grade USB-C interface, so as to be plugged into an external display to present the image captured by the camera 40 on the external display in real time.

[0044] The camera 40 used in the present application may be, but is not limited to, a CMOS camera 40 with a pixel of more than 2 million.

[0045] In summary, the implementation of the technical solution of this embodiment will achieve the following beneficial effects: the endoscope system 100 of this solution can be applied to auxiliary treatment activities of cardiovascular, neurovascular, peripheral vascular and other lesion sites. When in use, the carrier tube 30 is inserted into the body from the hole or opening on the patient's body and delivered to the lesion site. At this time, the camera 40 preset at the end of the carrier tube 30 can face the lesion site, and then can directly capture the real-time image of the lesion site. The acquired image data is transmitted to the image processing chip, and after pre-processing, it is transmitted to the external in vitro display through the shielded wire 20. In this way, the doctor can observe the image of the lesion site on the in vitro display in real time, so as to effectively grasp the lesion condition of the lesion site, perform auxiliary surgery, etc. Compared with the prior art, it can also abandon the use of radiation and contrast agents, eliminate the risks and hidden dangers of kidney damage and radiation exposure, and improve the safety and reliability of treatment.

[0046] Please continue reading Figure 3 and Figure 4 On the basis of the above embodiment, a guide cavity 31 is formed inside the carrier tube 30, and the inside of the guide cavity 31 is used to pass a guide wire. The guide cavity 31 is used to pass a guide wire and is installed inside it, so that the guide wire can extend from the end of the carrier tube 30 away from the operating handle 10. The guide wire is used to guide the endoscope into the human organ (such as the blood vessel 200 in this case). Especially in narrow or complex anatomical structures, the guide wire can help the endoscope pass through these areas smoothly, ensuring that the endoscope can reach the target position.

[0047] For example, the inner diameter of the guide cavity 31 is 0.3 mm to 8 mm, and can accommodate guide wires of 0.014 inches, 0.018 inches, 0.035 inches, and 0.038 inches.

[0048] Furthermore, in order to facilitate the support tube 30 to pass through narrow or complex anatomical structures smoothly, in one embodiment, a conical structure is formed on the tube end wall of the support tube 30 away from the operating handle 10 and corresponding to one end of the guide cavity 31 .

[0049] It is easy to understand that the tapered structure allows the supporting tube 30 to have better passability and reduce the resistance of body tissues or organs during movement.

[0050] Furthermore, in order to reduce the resistance of the back suction moving in the guide cavity 31 , in an optional embodiment, the cavity wall of the guide cavity 31 is provided with a lubricating medium.

[0051] Specifically, the lubricating medium may be any one of a PTFE (polytetrafluoroethylene) lubricating layer, lubricating grease, lubricating oil, etc., and may be flexibly selected according to actual needs.

[0052] Please continue reading Figure 3 In addition, based on any of the above embodiments, the endoscope system 100 further includes a light source 50 , which is mounted at one end of the supporting tube 30 away from the operating handle 10 , and the light source 50 is arranged in cooperation with the camera 40 .

[0053] It is easy to understand that the camera 40 inserted into the human tissue or organ (such as the blood vessel 200 in this case) is in a closed and dark environment, which is extremely unfavorable for the camera 40 to obtain bright and clear images, or it increases the difficulty of the camera 40 to obtain high-quality images, and puts higher requirements on the performance of the camera 40 itself, thereby increasing the cost. By integrating the light source 50 at the end of the supporting tube 30 near the camera 40, the light source 50 provides auxiliary light after lighting, which can provide the camera 40 with a bright shooting field of view, which is helpful for obtaining higher quality shooting images and reducing costs.

[0054] Optionally, the light source 50 adopts an LED light source, which can be any one of LED lamp beads, LED lamp tubes, LED light strips, etc., and can be flexibly selected according to actual needs.

[0055] Please continue reading Figure 4In addition, in one embodiment, the endoscope system 100 also includes a light signal line 60 and an image signal line 60a, both of which are inserted into the lumen of the carrier tube 30, and one end of the light signal line 60 and the image signal line 60a are electrically connected to the image processing chip, the other end of the light signal line 60 is electrically connected to the light source 50, and the other end of the image signal line 60a is electrically connected to the camera 40.

[0056] That is, by setting the light signal line 60 and the image signal line 60a, a wired signal connection between the light source 50 and the camera 40 and the image processing chip is achieved, which can ensure the accuracy of communication and has higher reliability and stability than wireless communication.

[0057] Please continue reading Figure 1 , Figure 6 and Figure 7 Furthermore, the endoscope system 100 also includes a balloon 70 and a connector 70a. The balloon 70 is installed at one end of the supporting tube 30 away from the operating handle 10, and the connector 70a is installed at one end of the operating handle 10 close to the supporting tube 30. A liquid flow cavity 32 is formed inside the supporting tube 30, and the liquid flow cavity 32 connects the balloon 70 and the connector 70a.

[0058] For example, when the lesion site is the blood vessel 200, the camera 40 needs to be inserted into the interior of the blood vessel 200, and the connector 70a is connected to the external liquid supply device, so that the liquid can be injected into the balloon 70 through the connector 70a and the liquid flow cavity 32, so that the balloon 70 expands and becomes larger to block and cut off the blood in the blood vessel 200, thereby preventing the blood from filling the field of view of the camera 40 and affecting the shooting clarity.

[0059] Furthermore, a flushing liquid cavity is formed inside the supporting tube 30, and the flushing liquid cavity is used to guide the flushing liquid to flush the diseased blood vessel 200 to flush out the residual blood, obtain a clearer and cleaner field of view, and improve the clarity and quality of the image taken by the camera 40.

[0060] Optionally, the liquid used to inject the balloon 70 and flush the diseased blood vessel 200 may be, but is not limited to, physiological saline or the like.

[0061] Optionally, the length of the balloon 70 is 8 mm to 15 mm, the material is polyurethane, and the bursting pressure is ≥30 atm.

[0062] The proximal end of the balloon 70 (ie, the end close to the operating handle 10 ) is also provided with two or more radioactive marking points to facilitate tracking and positioning of the position of the balloon 70 in the patient's body.

[0063] Optionally, the connector 70a adopts a Luer connector, which is easy to install and disassemble, and the operation is convenient and labor-saving.

[0064] Please continue reading Figure 1 and Figure 5 In addition, based on any of the above embodiments, the endoscope system 100 further includes a snake-bone structure 80, which is installed at one end of the supporting tube 30 away from the operating handle 10, and the outer surface of the snake-bone structure 80 is coated with a hydrophilic coating.

[0065] Furthermore, the endoscope system 100 also includes a bending control mechanism 90, which is movably mounted on the operating handle 10 and is drivingly connected to the snake-bone structure 80 to drive the snake-bone structure 80 to bend so as to change the shooting angle of the camera 40.

[0066] The snake-bone structure 80 has the ability to bend and deform, and can flexibly change the shooting angle of the camera 40 so as to capture images of different angles at different parts of the lesion, which is convenient for doctors to have a more comprehensive understanding of the lesion and provide more accurate treatment and surgical plans.

[0067] Since the snake-bone structure 80 also needs to penetrate into human tissues such as the blood vessels 200 , the hydrophilic coating provided on the surface of the snake-bone structure 80 can prevent blood and other human tissue fluids from being contaminated on the snake-bone structure 80 .

[0068] For example, the hydrophilic coating uses polyvinyl pyrrolidone (PVP) with a thickness of 2μm~5μm and a friction coefficient of ≤0.1 (ASTMD1894 standard).

[0069] When in use, the doctor can flexibly adjust the curvature, curvature direction, etc. of the snake bone structure 80 by operating the curvature control mechanism 90 .

[0070] Specifically, in the above embodiment, the bending control mechanism 90 includes a rotating wheel 91, a first traction member 92, a second traction member 93 and a handle member 94. The rotating wheel 91 is rotatably arranged on the operating handle 10, one end of the first traction member 92 is wrapped around the rotating wheel 91, and the other end of the first traction member 92 is used to connect to one side of the snake-bone structure 80, one end of the second traction member 93 is wrapped around the rotating wheel 91, and the other end of the second traction member 93 is connected to the other side of the snake-bone structure 80, and the handle member 94 is fixed to the rotating wheel 91 to drive the rotating wheel 91 to rotate in both directions.

[0071] It is easy to understand that when the operating handle 94 drives the rotating wheel 91 to rotate in the clockwise direction, the first traction member 92 is released and the second traction member 93 is retracted. At this time, the second traction member 93 forms a pulling effect on the snake-bone structure 80, thereby driving the snake-bone structure 80 to bend in the first direction; similarly, when the operating handle drives the rotating wheel 91 to rotate in the counterclockwise direction, the first traction member 92 is retracted and the second traction member 93 is released. At this time, the first traction member 92 forms a pulling effect on the snake-bone structure 80, thereby driving the snake-bone structure 80 to bend in the second direction. The first direction and the second direction can also be two opposite directions or any angle direction less than 180°. In this way, the snake-bone structure 80 can drive the camera 40 to change the shooting angle to obtain images of different parts of the lesion.

[0072] For example, the snake-bone structure 80 is composed of 12-24 sets of titanium-nickel alloy joint rings, and the bending radius is 2mm~15mm.

[0073] For example, the first traction member 92 and the second traction member 93 may be traction wires with a diameter of 0.1 mm.

[0074] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
