[0002] An endoscope is a medical device that enters the body through natural cavities or tiny incisions for observation, diagnosis, or treatment. It can transmit images inside the body in real time and is widely used in disease examination and minimally invasive surgery in fields such as gastroenterology, respiratory medicine, and urology. An endoscope generally consists of a tip, a curved section, and an insertion section. The curved section is located between the tip and the insertion section. The tip houses the camera lens and illumination source, while the curved section contains the serrated edge and various tubing.

[0003] To obtain higher quality video footage, a high-brightness lighting source is usually required. However, a high-brightness lighting source will generate a lot of heat at the front end, causing the temperature of the front end to rise rapidly. This not only affects the lifespan of the camera system and sensor components, but also can easily burn the patient. Summary of the Invention

[0004] This invention provides an endoscope tip and its manufacturing method, which can reduce the temperature of the tip while ensuring high-brightness illumination.

[0005] The embodiments of the present invention can be implemented as follows: An embodiment of the present invention provides an endoscope tip, comprising: The tip holder has a honeycomb structure. Snake bone, the end of the snake bone is connected to the tip head seat; The pipe is inserted into the tip head seat. The pipe is located inside the snake bone and forms a spacer chamber between the pipe and the snake bone. The heat-conducting structure has one end that is adapted to and fits the honeycomb structure, and the other end of the heat-conducting structure is provided with a plug, which seals the heat-conducting structure in the partition cavity.

[0006] Optionally, the snake bone is covered with a mesh sleeve and a soft covering layer, with the soft covering layer covering the outside of the mesh sleeve, and the mesh sleeve having multiple micropores distributed on it.

[0007] Optionally, the thermally conductive structure includes thermally conductive particles that can pass through micropores.

[0008] Optionally, the heat-conducting structure includes a sheath, a sleeve, and heat-conducting particles. One end of the sleeve is connected to the tip head seat and communicates with the honeycomb structure, and the other end of the sleeve is connected to the sheath. The sheath and the inside of the sleeve are filled with heat-conducting particles.

[0009] Optionally, the heat-conducting structure includes a hollow corrugated tube and heat-conducting particles, with both ends of the hollow corrugated tube connected to a tip head seat and a plug, respectively, and the heat-conducting particles filling the interior of the hollow corrugated tube.

[0010] Optionally, the inner and outer walls of the hollow corrugated pipe are coated with a thermally conductive coating.

[0011] Optionally, the thermally conductive particles are nanoscale graphene particles or graphene-silicone grease composite particles.

[0012] Optionally, the plug is provided with a honeycomb structure, the honeycomb structure is filled with thermally conductive silicone grease, and the thermally conductive silicone grease is in contact with the thermally conductive particles.

[0013] Optionally, the snake bone is coated with a thermally conductive coating.

[0014] An embodiment of the present invention also provides a manufacturing method for manufacturing the above-mentioned endoscope tip, comprising the following steps: The heating element is assembled to the tip head base and fixedly connected to the tip head base; Weld the steel wire to the snake bone; The snake bone with welded steel wire is connected to the tip head seat equipped with the heating element. Install and secure the tubing inside the snake skeleton; The heat-conducting structure is placed in the partition chamber, so that the end of the heat-conducting structure is connected to the honeycomb structure of the tip head seat; Install the plug and fix it to the snake bone or the tube body connected to the snake bone to prevent the heat-conducting structure from coming off.

[0015] Beneficial effects of the embodiments of the present invention: The endoscope tip of this invention includes a tip base, a snake-like skeleton, a tube, and a heat-conducting structure. The tip base has a honeycomb structure. The end of the snake-like skeleton is connected to the tip base. The tube is inserted into the tip base and is located inside the snake-like skeleton, forming a spacer chamber between the tube and the skeleton. One end of the heat-conducting structure is adapted to and fits the honeycomb structure, and the other end of the heat-conducting structure has a plug that seals the heat-conducting structure within the spacer chamber. This invention provides a heat-conducting structure inside the snake-like skeleton, which connects to the tip base. This allows heat from the tip base to be guided to the rear end of the snake-like skeleton, thereby reducing the temperature of the tip base. Simultaneously, the honeycomb structure on the tip base provides a large heat transfer area between the heat-conducting structure and the tip base, increasing the speed of heat transfer and preventing a rapid temperature rise in the tip base. This not only ensures the lifespan of the camera lens or sensor components but also eliminates the risk of burning the patient.

[0016] The manufacturing method includes assembling the heating element to the tip head and fixing it to the tip head; welding the steel wire to the serpentine frame; connecting the serpentine frame with the welded steel wire to the tip head containing the heating element; assembling and fixing a pipe inside the serpentine frame; placing a heat-conducting structure in the partition chamber, with the end of the heat-conducting structure connected to the honeycomb structure of the tip head; installing a plug and fixing the plug to the serpentine frame or the pipe connected to the serpentine frame to prevent the heat-conducting structure from detaching. Since this manufacturing method is used to manufacture the aforementioned endoscope tip, the method for manufacturing the aforementioned endoscope tip possesses all the functions of an endoscope tip.

[0027] It should be noted that, for the sake of simplicity, the aforementioned method embodiments are all described as a series of actions.

[0028] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0029] As described in the background section, a medical electronic endoscope is a medical device that enters the body through natural cavities or tiny incisions for observation, diagnosis, or treatment. It generally includes an endpiece containing a lens and illumination source, a curved section, a slender insertion section, an operating section for medical personnel to hold, an image processing system, etc., capable of transmitting in-body images in real time, and widely used in disease examination and minimally invasive surgery in fields such as gastroenterology, respiratory medicine, and urology. The curved section is located between the endpiece and the insertion section; the endpiece houses the camera lens and illumination source (heating component), while the curved section contains a serrated edge and various tubing.

[0030] To obtain high-quality video footage, a high-brightness illumination source is usually required. However, this high-brightness illumination source generates a lot of heat at the tip. In addition, to allow the tip of the endoscope to enter small-diameter cavities, it is molded as a single piece, making the tip smaller. The heat-generating high-brightness illumination source installed on the smaller tip results in poor heat dissipation, causing the tip temperature to rise rapidly. This not only affects the lifespan of the camera system, illumination source, and sensor components, but also easily burns the patient.

[0031] Therefore, embodiments of the present invention provide an endoscope tip and a method for manufacturing the same, which can solve the above-mentioned problems, and will be described in detail below.

[0032] Please refer to Figures 1 to 5 The endoscope tip includes a tip base 1, a snake bone 2, a tube 3, and a heat-conducting structure 5. The tip base 1 is provided with a honeycomb structure 10. The end of the snake bone 2 is connected to the tip base 1. The tube 3 is inserted into the tip base 1. The tube 3 is located inside the snake bone 2 and forms a spacer chamber 4 between the tube 3 and the snake bone 2. One end of the heat-conducting structure 5 is adapted to and fits the honeycomb structure 10. The other end of the heat-conducting structure 5 is provided with a plug 6, which seals the heat-conducting structure 5 in the spacer chamber 4.

[0033] In this embodiment of the invention, the endoscope tip has a heat-conducting structure 5 inside the snake bone 2, which is connected to the tip mount 1. The heat-conducting structure 5 conducts heat from the tip mount 1 to the rear end of the snake bone 2, thereby reducing the temperature of the tip mount 1. Simultaneously, the tip mount 1 has a honeycomb structure 10, which increases the heat-conducting contact area between the heat-conducting structure 5 and the tip mount 1, improving the speed of heat transfer and facilitating rapid cooling of the tip mount 1. While maintaining a high-brightness lighting environment and a small tip size, the upper limit of the tip's operating temperature is reduced. This not only ensures the lifespan of the camera lens or sensor components at the tip but also eliminates the risk of burning the patient, resulting in a better surgical experience. In this embodiment, the honeycomb structure 10 of the tip mount 1 further increases the heat-conducting contact area while ensuring its supporting strength.

[0034] The endoscope includes a heating element 7 mounted on the tip head 1. This heating element 7 comprises a camera system or a special probe and sensor. The camera system includes a camera lens and an illumination source, which can be an LED light. The camera system's wiring harness passes through the tip head 1 and the serpentine frame 2, extending to the insertion section. The serpentine frame 2 is located at the curved section of the endoscope. Inside the serpentine frame 2 are arranged pipes 3, which are a general term for various types of pipes, including wiring harness pipes, clamp pipes, water supply pipes, and air supply pipes. These pipes are all inserted into the tip head 1, which has corresponding insertion openings. The two ends of the tip head 1 are connected to the serpentine frame 2 and the tip head shell 11, respectively. The tip head shell 11 is inserted into and bonded to the tip head 1, and the serpentine frame 2 is fitted onto the tip head 1. Alternatively, when the tip head 1 is manufactured as a single piece, the tip head 1 and the tip head shell 11 can be made as a single unit.

[0035] A steel wire 8 is welded and fixed to the snake bone 2. One end of the steel wire 8 is fixed to the end of the snake bone 2 near the tip head seat 1, and the other end of the steel wire 8 passes through the wire groove on the inner side wall of the snake bone 2 and extends to the insertion part. A mesh sleeve 20 and a covering soft layer 21 are also provided on the outside of the snake bone 2. The mesh sleeve 20 is in contact with the outer surface of the snake bone 2, and the covering soft layer 21 covers the outside of the mesh sleeve 20. A heat-conducting structure 5 is disposed between the tip head seat 1 and the plug 6. The plug 6 is fixed to the end of the snake bone 2 or fixed to the insertion part connected to the snake bone 2 to prevent the heat-conducting structure 5 from detaching from the tip head seat 1. The heat-conducting structure 5 can take many forms; several examples will be listed below.

[0036] Example 1 refer to Figure 3 and Figure 4The heat-conducting structure 5 consists of heat-conducting particles 50, which fill the spacer chamber 4 formed by the snake bone 2 and the pipe 3. The mesh sleeve 20 has multiple micropores, the diameter of which is larger than the particle size of the heat-conducting particles 50, allowing them to pass through and enter the outside of the mesh sleeve 20. Because the mesh sleeve 20 is covered with a soft covering layer 21 (generally a rubber sleeve of suitable thickness can be used), the heat-conducting particles 50 will not leak out, nor will they enter the pipe 3. The heat-conducting particles 50 need to have excellent thermal conductivity so that they can quickly conduct heat from the tip head seat 1 to the rear of the snake bone 2 during contact with the honeycomb structure 10 of the tip head seat 1.

[0037] The thermally conductive particles 50 can be nanoscale graphene particles or composite particles made of graphene and silicone grease. Graphene has excellent thermal conductivity and heat dissipation, and its thermal conductivity is superior to that of traditional metal materials such as copper and aluminum. This allows for highly efficient heat exchange with the tip mount 1, transferring heat from the tip mount 1 to the rear end of the snake bone 2. This effectively prevents the tip mount 1 from overheating, resulting in a better surgical experience and improved surgical safety. For example, if the graphene particles have a diameter of less than 500 nanometers and the micropores of the mesh sleeve 20 have a diameter greater than 500 nanometers, the graphene particles can contact the covering soft layer 21 through the micropores of the mesh sleeve 20. When the snake bone 2 bends, the covering soft layer 21 deforms and has a certain degree of resilience. The graphene particles will change position with the deformation of the covering soft layer 21, allowing the snake bone 2 to bend and be manipulated normally. The filled graphene particles will not affect the normal bending and use of the snake bone 2. Of course, composite particles made of graphene and silicone grease also have excellent thermal conductivity and heat dissipation performance, and will not affect the normal bending and use of the snake bone 2.

[0038] In addition, graphene particles also have a lubricating function. When graphene particles are filled inside the snake bone 2, they can reduce the friction between the steel wire 8 and the snake bone 2, reduce the friction between the mesh sleeve 20 and the snake bone 2, and reduce the friction between the soft covering layer 21 and the mesh sleeve 20. This makes the bending operation of the bending part smoother during use.

[0039] Alternatively, graphene particles are generally made into spherical shapes. Spherical graphene particles have low friction with each other, which can effectively avoid hindering the bending of the snake bone 2.

[0040] A plug 6 is installed at the end of the snake bone 2, and the plug 6 is fixed to the snake bone 2. The plug 6 is used to seal the graphene particles and prevent the graphene particles from overflowing into the insertion part. Of course, the plug 6 has holes that extend through both ends of the plug 6, and these holes allow the installed pipe 3 to pass through. Alternatively, a honeycomb structure 10 can be installed on the plug 6, so that the honeycomb structure 10 comes into contact with the graphene particles to achieve rapid heat conduction and dissipation.

[0041] To increase the heat transfer efficiency between graphene particles and the snake bone 2, a thermally conductive coating can be applied to the outer wall of the snake bone 2 to improve the heat conduction and transfer rate. The material of the thermally conductive coating can be a composite material of copper and diamond, or nano-carbon or graphene materials. Similarly, in order to enable heat to be quickly transferred from the snake bone 2 to the covering soft layer 21 and thus achieve heat dissipation, a thermally conductive coating can also be provided on the mesh sleeve 20.

[0042] Example 2 refer to Figure 5 The heat-conducting structure 5 includes a sheath 51, a sleeve 52 and heat-conducting particles 50. One end of the sleeve 52 is connected to the tip head seat 1 and communicates with the honeycomb structure 10. The other end of the sleeve 52 is connected to the sheath 51. The sheath 51 and the sleeve 52 are filled with heat-conducting particles 50.

[0043] Specifically, the sleeve 52 is a thin-walled metal tube, with its two ends connected to the tip head 1 and the sheath 51, respectively. The interior of the sleeve 52 is connected to the honeycomb structure 10 of the tip head 1. The interior of the sheath 51 is filled with heat-conducting particles 50, which can enter the honeycomb structure 10 to achieve heat conduction and heat exchange with the tip head 1. The honeycomb structure 10 is adapted to the heat-conducting particles 50, thus providing a large heat conduction and heat exchange area. For example, if the honeycomb structure 10 is a circular honeycomb groove, then the heat-conducting particles 50 are preferably also spherical particles. Of course, the honeycomb structure 10 can also be a hexagonal honeycomb groove, a partition-type honeycomb groove, or other shapes of honeycomb grooves, which are not limited. In this embodiment, the heat-conducting particles 50 can also be graphene particles or composite particles made of graphene and silicone grease.

[0044] Meanwhile, the number of sheaths 51 and sleeves 52 is multiple, which helps to increase the heat conduction and heat transfer rate. Sheaths 51 can be made of soft and elastic plastic or rubber. Sleeves 52 can be made of metal tubes such as copper or aluminum.

[0045] Example 3 The heat-conducting structure 5 includes a hollow corrugated tube and heat-conducting particles 50. The two ends of the hollow corrugated tube are connected to the tip head seat 1 and the plug 6, respectively. The interior of the hollow corrugated tube is hollow, and the heat-conducting particles 50 are filled inside the hollow corrugated tube.

[0046] The hollow corrugated pipe can be a commercially available double-wall corrugated pipe. Both the double-wall corrugated pipe and the tip seat 1 are made of metal. The double-wall corrugated pipe is snap-fitted or welded to the tip seat 1, allowing heat transfer from the tip seat 1 to the double-wall corrugated pipe. Similarly, the plug 6 is also made of metal and is welded to the double-wall corrugated pipe. The plug 6 also has a honeycomb structure 10. Both the honeycomb structure 10 of the plug 6 and the honeycomb structure 10 of the tip seat 1 are filled with thermally conductive silicone grease, which mixes and contacts with the thermally conductive particles 50. Simultaneously, thermally conductive silicone grease is also filled within the interlayer of the double-wall corrugated pipe. Of course, besides filling the interior of the double-wall corrugated pipe with thermally conductive particles 50, thermally conductive silicone grease can also be used, or no thermally conductive material may be selected.

[0047] Thermal grease can include fillers such as diamond powder, graphene, boron nitride, aluminum nitride, aluminum oxide, and zinc oxide to increase the heat transfer rate. In addition to its good thermal conductivity and sealing properties, thermal grease also has a certain degree of lubrication, which can reduce friction between pipe 3 and plug 6.

[0048] Optionally, the inner and outer walls of the hollow corrugated pipe are coated with a thermally conductive coating. The material of the thermally conductive coating can be a composite material of copper and diamond, or nano-carbon or graphene.

[0049] In this embodiment of the invention, the endoscope tip has a honeycomb structure 10 on the tip seat 1, and a highly thermally conductive material such as graphene is placed inside the snake bone 2. When the endoscope is working, the heat generated by the high-heat illumination source can be quickly transferred to the snake bone 2 and the rear end of the snake bone 2 through the heat-conducting structure 5, which increases the heat dissipation area, avoids heat concentration at the tip, effectively prevents the tip temperature from becoming too high, makes the surgical experience better, and improves the safety of the surgery.

[0050] An embodiment of the present invention also provides a manufacturing method for manufacturing the above-mentioned endoscope tip, comprising the following steps: S1: Assemble the heating element 7 onto the tip head seat 1 and fix it to the tip head seat 1; if a tip head shell 11 is provided, the tip head shell 11 needs to be installed on top of the tip head seat 1 and glued together. S2: Weld the steel wire 8 to the snake bone 2; S3: Connect the snake bone 2 with the welded steel wire 8 to the tip head seat 1 equipped with the heating element 7. S4: Assemble and fix the pipe 3 inside the snake bone 2; the pipe 3 can be of various types, and the installation and fixing of each pipe is adapted to the channel port on the tip head seat 1. The pipe 3 is inserted into the tip head seat 1. S5: The heat-conducting structure 5 is placed in the spacer chamber 4, so that the end of the heat-conducting structure 5 is connected to the honeycomb structure 10 of the tip head seat 1; for example, graphene particles are added in the spacer chamber 4; or, a sheath 51 and a sleeve 52 are arranged, and graphene particles are added in the sheath 51 and the sleeve 52; or, a hollow corrugated pipe is arranged. S6: Install the plug 6 and fix the plug 6 to the snake bone 2 or the tube body connected to the snake bone 2 to prevent the heat conduction structure 5 from coming out; the wire harness, steel wire 8 and each tube of the heating element 7 pass through the hole of the plug 6.

[0051] In addition, before S4, a mesh sleeve 20 can be welded to the outside of the snake bone 2, and a soft covering layer 21 can be applied to the outside of the mesh sleeve 20.

[0052] In this embodiment, the heating component 7 includes a camera and a lighting source.

[0053] The manufacturing method of this invention can produce an endoscope tip with rapid heat dissipation without affecting the small-sized structure of the tip, while achieving rapid heat dissipation.

[0054] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
