Description

Technical Field

[0001] This utility model belongs to the field of endoscope insertion technology, and in particular relates to a dual-fluorescent endoscope insertion structure that prevents detachment. Background Technology

[0002] An endoscope is a medical device used to observe internal organs or cavities of the human body. With the help of an endoscope, doctors can observe ulcers or tumors in the stomach and see lesions that cannot be seen by X-rays, and formulate the best treatment plan accordingly. Therefore, it is widely used in diagnosis, treatment and minimally invasive surgery.

[0003] There are many types of endoscopes on the market. For example, a 4K dual-fluorescence rigid endoscope is disclosed on the Chinese Patent Network. Its announcement number is CN220608290U. This endoscope structure can be used in tumor detection, minimally invasive surgery assistance and other fields. However, there are some defects and shortcomings that need to be improved: (1) Most of the existing endoscopes are integrated structures. Once the various functional components are fixed together, they are difficult to disassemble at will, which makes it inconvenient to maintain and replace the relevant functional components; (2) When the endoscope is working, it needs to be electrically connected to the various functional components through optical fiber cables and other wires. However, due to the structural design of some existing endoscopes, when the wires are inserted into the corresponding interfaces, there is often a lack of effective fixing measures, which makes the wires easy to fall off, thus affecting the normal operation of the endoscope; (3) Some existing endoscopes use bolts and other fasteners to connect and fix the various functional components. Although this can prevent the wires from falling off, tools are needed for disassembly and assembly, which increases the difficulty of maintenance and replacement of components. Therefore, in view of the above problems, the anti-fall-off dual-fluorescence endoscope plug-in structure provided by this utility model is of great significance. Utility Model Content

[0004] This invention provides a dual-fluorescent endoscope connector structure designed to prevent detachment. Through modular design, each functional component can be disassembled as needed for maintenance and replacement. The connector, plug rod, and plug slot work together to secure it, effectively preventing detachment from the first and second connectors and thus preventing the first and second optical fibers from falling off. By rotating the first and second optical fibers and aligning the plug rod with the center of the plug hole, and then pulling the plug rod along with the plug rod out of the plug hole, the first and second optical fibers can be removed from the endoscope body for maintenance and replacement. The entire disassembly and assembly process requires no tools, significantly reducing the difficulty of maintenance and replacement, thus solving the problems in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a dual-fluorescent endoscope connector structure for preventing detachment, comprising an endoscope body, on which a first wiring port and a second wiring port are respectively provided. A connector is fixedly connected to the edge of each of the first and second wiring ports. The connector is circular, with a pair of connector holes and a pair of connector grooves on its surface. A first optical fiber and a second optical fiber are respectively connected to the first and second wiring ports. A connector is provided at one end of each of the first and second optical fibers, with the diameter of the connector being equal to the inner diameter of the first and second wiring ports. A pair of protrusions are fixedly connected to the outer wall of the end of each of the first and second optical fibers near the connector. A connector rod is fixedly connected to the protrusion, and a limit block is fixedly connected to the end of the connector rod. A mounting base is fixedly connected to one end of the endoscope body, and a scope tube is mounted on the mounting base. A light guide hole is provided at the end of the scope tube, and a camera is mounted at the end of the scope tube.

[0007] Furthermore, the insertion hole is circular, the insertion groove is arc-shaped with one end connected to the insertion hole, and the groove width is smaller than the hole diameter. The diameter of the insertion rod is equal to the groove width, and the center of each insertion rod corresponds one-to-one with the center of each insertion hole. The limiting block is circular, and its diameter is equal to the hole diameter.

[0008] Furthermore, the mounting base is circular, with its outer diameter being equal to the inner diameter of the mirror tube, and the outer wall of the mounting base and the inner wall of the mirror tube are respectively engraved with mutually mating external threads and internal threads.

[0009] Furthermore, the end of the end tube is a spherical end face.

[0010] Furthermore, the endoscope body is fitted with an anti-slip sleeve, the inner diameter of which is equal to the diameter of the endoscope body, and the surface of the anti-slip sleeve is engraved with herringbone anti-slip patterns.

[0011] Furthermore, the surface of the endoscope body is provided with several slots, and the inner wall of the anti-slip sleeve is provided with several blocks. The blocks and slots are both rectangular, and the number of blocks is the same. The thickness of the blocks is equal to the width of the slots.

[0012] The present invention has the following advantages over the prior art:

[0013] (1) In the present invention, the anti-detachment dual fluorescent endoscope plug-in structure is designed in a modular manner, and each functional component can be disassembled as needed for maintenance and replacement of the relevant components.

[0014] (2) When using the anti-detachment dual fluorescent endoscope plug-in structure of this utility model, the joint of the limiting block, plug-in rod and plug-in groove can fix the plug-in connector after plugging in, so as to effectively prevent the connector from detaching from the first wiring port and the second wiring port and causing the first optical fiber to detach from the second optical fiber.

[0015] (3) When using the anti-detachment dual fluorescent endoscope insertion structure of this utility model, by rotating the first optical fiber and the second optical fiber and aligning the limiting block with the center of the insertion hole, the insertion rod and the limiting block are pulled out of the insertion hole together, so that the first optical fiber and the second optical fiber can be removed from the endoscope body for maintenance and replacement of related components. The entire disassembly and assembly process does not require the use of tools, which greatly reduces the difficulty of maintenance and replacement of components.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Please see Figure 1-6As shown, this utility model discloses an anti-detachment dual-fluorescent endoscope connector structure, comprising an endoscope body 1. The endoscope body 1 has a first connector 2 and a second connector 3. Connectors 4 are fixedly connected to the edges of both the first and second connectors 2 and 3. The connector 4 is circular, with a pair of connector holes 5 and a pair of connector grooves 6 on its surface. A first optical fiber 7 and a second optical fiber 8 are connected to the first and second connectors 2 and 3, respectively. One end of each optical fiber 7 and optical fiber 8 has a connector 9, the diameter of which is equal to the inner diameter of the first and second connectors 2 and 3. The other ends of the first and second optical fibers 7 and 8 are electrically connected to a camera host and a dual-fluorescent light source, respectively. The camera host can transmit the images captured by the endoscope body 1 to an external display for image output. The dual-fluorescent light source provides dual-wavelength excitation light (such as blue light and near-infrared light) to the endoscope body 1. Each wavelength is specifically designed to excite different types of fluorescent dyes or probes. The excitation light source is alternately or synchronously irradiated, and different tissues emit fluorescence in different bands. Doctors can view the fused image on a monitor to clarify the location and extent of the lesion. A pair of protrusions 10 are fixedly connected to the outer wall of the first fiber optic cable 7 and the second fiber optic cable 8 near the connector 9. A plug rod 11 is fixedly connected to the protrusion 10, and a limit block 12 is fixedly connected to the end of the plug rod 11. A mounting base 13 is fixedly connected to one end of the endoscope body 1. A scope tube 14 is installed on the mounting base 13. A light guide hole 15 is opened at the end of the scope tube 14, and a camera 16 is installed at the end of the scope tube 14. The dual fluorescent light source can be transmitted to the light guide hole 15 through the first fiber optic cable 7 and the second fiber optic cable 8, and then transmitted to the working end of the endoscope body 1 through the light guide hole 15 to achieve uniform illumination. The camera 16 can simultaneously capture two fluorescent signals and convert them into image signals to obtain the required lesion imaging.

[0029] The insertion hole 5 is circular, and the insertion groove 6 is arc-shaped, with one end connected to the insertion hole 5. The groove width of the insertion groove 6 is smaller than the diameter of the insertion hole 5. The diameter of the insertion rod 11 is equal to the groove width of the insertion groove 6, and the center of each insertion rod 11 corresponds one-to-one with the center of each insertion hole 5. The limiting block 12 is circular, and its diameter is equal to the diameter of the insertion hole 5. When the connectors 9 on the first optical fiber 7 and the second optical fiber 8 are respectively inserted into the first connector 2 and the second connector 3, the insertion rod 11 and the limiting block 12 can be aligned and pass through the corresponding insertion hole 5. At this time, rotating the first optical fiber 7 and the second optical fiber 8 can cause the protrusion 10, along with the insertion rod 11 and the limiting block 12, to deflect along the insertion groove 6, causing the limiting block 12 to deviate from the center of the insertion hole 5. Since the diameter of the limiting block 12 is larger than the width of the insertion slot 6, the joint action of the limiting block 12, the insertion rod 11, and the insertion slot 6 can fix the connector 9 after insertion, effectively preventing the connector 9 from detaching from the first connection port 2 and the second connection port 3, which would cause the first optical fiber 7 and the second optical fiber 8 to fall off. When it is necessary to disassemble the first optical fiber 7 and the second optical fiber 8, rotate the first optical fiber 7 and the second optical fiber 8 again so that the limiting block 12 is aligned with the center of the insertion hole 5, and then pull the insertion rod 11 together with the limiting block 12 out of the insertion hole 5. The first optical fiber 7 and the second optical fiber 8 can then be removed from the endoscope body 1 for maintenance and replacement of related components. The entire disassembly and assembly process does not require tools, which greatly reduces the difficulty of maintaining and replacing components.

[0030] The mounting base 13 is circular, and its outer diameter is equal to the inner diameter of the lens tube 14. The outer wall of the mounting base 13 and the inner wall of the lens tube 14 are respectively engraved with matching external and internal threads. The lens tube 14 is made of flexible tubing and can be fixed to the mounting base 13 by threaded connection. The lens tube 14 can be removed from the mounting base 13 by twisting it to facilitate maintenance and replacement of related components.

[0031] The end of the endoscope tube 14 is a spherical end face. The spherical end face can effectively prevent the edge of the endoscope tube 14 from being too sharp when it is inserted into the patient's body, which could cause discomfort or even injury to the patient.

[0032] The endoscope body 1 is fitted with an anti-slip sleeve 17. The inner diameter of the anti-slip sleeve 17 is equal to the diameter of the endoscope body 1, and the surface of the anti-slip sleeve 17 is engraved with herringbone anti-slip texture. When the endoscope body 1 is held and operated, the anti-slip texture on the surface of the anti-slip sleeve 17 can increase the friction between the hand and the endoscope body 1, so as to play an anti-slip role and prevent slipping and displacement of the endoscope body 1 during operation.

[0033] The endoscope body 1 has several slots 18 on its surface and several blocks 19 on the inner wall of the anti-slip sleeve 17. Both the blocks 19 and the slots 18 are rectangular and the same number of them are provided. The thickness of the blocks 19 is equal to the width of the slots 18. When the anti-slip sleeve 17 is fitted onto the endoscope body 1, each block 19 can be aligned and inserted into the corresponding slot 18. The mutual cooperation between the blocks 19 and the slots 18 can play a limiting role to prevent the anti-slip sleeve 17 from deflecting or shifting.

[0034] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0035] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all connected to the external main controller and 220V mains power. The main controller is a conventional known device that can play a control role.

[0036] The working principle of this utility model is as follows:

[0037] In use, the connectors 9 on the first optical fiber 7 and the second optical fiber 8 can be inserted into the first wiring port 2 and the second wiring port 3 on the endoscope body 1, respectively. The other ends of the first optical fiber 7 and the second optical fiber 8 are electrically connected to the camera host and the dual fluorescent light source, respectively. By holding the endoscope body 1, the endoscope tube 14 can be inserted into the patient's abdominal cavity. The dual fluorescent light source can provide dual-wavelength excitation light (such as blue light and near-infrared light) to the endoscope body 1. The dual fluorescent light source can be transmitted to the light guide hole 15 through the first optical fiber 7 and the second optical fiber 8, and then transmitted to the working end of the endoscope body 1 through the light guide hole 15 to illuminate the target area. Then, the camera 16 can simultaneously capture the two fluorescent signals and convert them into image signals. The camera host can transmit the image captured by the endoscope body 1 to an external display for image output. The doctor can view the fused image on the display to clarify the location and extent of the lesion. When the connectors 9 are inserted into the first wiring port 2 and the second wiring port 3, the insertion rod 11 together with the limiting block 12 can be aligned and pass through the corresponding insertion hole 5. At this time, the first The fiber optic cable 7 and the second fiber optic cable 8 can cause the protrusion 10, along with the plug rod 11 and the limiting block 12, to deflect along the plug groove 6, and cause the limiting block 12 to deviate from the center of the plug hole 5. Since the diameter of the limiting block 12 is larger than the width of the plug groove 6, the joint action of the limiting block 12, the plug rod 11, and the plug groove 6 can fix the connector 9 after plugging, so as to effectively prevent the connector 9 from detaching from the first terminal 2 and the second terminal 3, causing the first fiber optic cable 7 and the second fiber optic cable 8 to fall off. When it is necessary to disassemble the first fiber optic cable 7, When connecting the second fiber optic cable 8, rotate the first fiber optic cable 7 and the second fiber optic cable 8 again so that the limiting block 12 is aligned with the center of the insertion hole 5. Then, pull the insertion rod 11 together with the limiting block 12 out of the insertion hole 5. The first fiber optic cable 7 and the second fiber optic cable 8 can then be removed from the endoscope body 1 for maintenance and replacement of related components. The entire disassembly and assembly process does not require tools, which greatly reduces the difficulty of maintaining and replacing components. The endoscope tube 14 can be removed from the mounting base 13 by twisting it to maintain and replace related components.
