[0003] In existing solutions, the vast majority of endoscope tips are made of plastic and manufactured using a one-piece molding process. However, plastic materials inherently suffer from low thermal conductivity and poor electrical conductivity: the former severely hinders heat transfer and dissipation, causing the tip temperature to rise continuously during use; the latter cannot effectively conduct static electricity, affecting the user experience. These two problems work together to ultimately reduce comfort during endoscope use and significantly increase safety risks.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall apply. Reagents or instruments whose manufacturers are not specified are all conventional products that can be purchased commercially.

[0021] This invention provides an endoscope tip mount 100 made of graphene-copper composite material, wherein the graphene-copper composite material comprises alternating copper layers 120 and graphene layers 110, as shown in the schematic diagram of the graphene-copper composite material structure. Figure 1 .

[0022] The endoscope tip mount 100 of this application uses a graphene-copper composite material comprising alternating layers of copper 120 and graphene 110, which gives the tip mount 100 good thermal conductivity. When applied to an endoscope, it helps to effectively reduce the tip temperature and improve the tip's antistatic performance. Before the application of the graphene-copper composite material, the endoscope tip mount 100 would experience black screen freezing and other phenomena at ±6KV during the antistatic test. After the application of the graphene-copper composite material, the endoscope tip mount 100 can still pass the antistatic test at ±8KV.

[0023] In an optional embodiment, the graphene is formed on the copper layer 120 by deposition. Specifically, the graphene deposition method can be chemical vapor deposition, and the parameters of the chemical vapor deposition include a temperature of 1000-1050℃, a pressure of 185-215Pa, and a time of 870-930s. Forming the graphene layer 110 by deposition is beneficial for controlling the deposition thickness of the graphene layer 110 and for improving the uniformity of the graphene layer 110.

[0024] In an optional embodiment, the graphene-copper composite material is obtained by hot-pressing a copper layer with graphene deposited on it. Specifically, multiple single-layer graphene-copper composite materials are placed flat in a vacuum hot-pressing mold. The mold is then evacuated to a pressure of -98 kPa to -101.325 kPa. A pressure of 10 MPa is continuously applied to both ends of the mold, while the temperature is maintained at 840°C to 860°C for 30 minutes, ultimately yielding the graphene-copper composite material.

[0025] In an optional embodiment, in the tip holder 100, the heat flow is parallel to the interface between the copper layer 120 and the graphene layer 110, for example, with Figure 1 For example, in the tip holder 100, the orientation of the graphene-copper composite material needs to be adjusted so that the heat generated by the light source 300, etc., is directed along the direction of the graphene-copper composite material. Figure 1 It flows in the vertical direction.

[0026] In an optional embodiment, the graphene-copper composite material contains 81-85% copper and 5-8% carbon. And / or, the graphene-copper composite material also includes oxygen, with an atomic percentage content of 9-12%.

[0027] The composition of graphene-copper composites affects the efficiency of heat transfer. When the composition of graphene-copper composites is within the above range, the graphene-copper composites have better thermal conductivity.

[0028] In an optional embodiment, the tip mount 100 includes an instrument channel 130 and a mounting groove 140 for mounting the camera system 200 and the light source 300. The mounting groove 140 is provided with a through hole for the wire 310 to pass through. The specific structure of the tip mount 100 is as follows: Figure 2 As shown.

[0029] The present invention also provides an endoscope tip device, such as... Figure 3 As shown, the device includes the tip head 100, the bending portion, and the camera system 200 and the light source 300 mounted on the tip head 100 as described in any of the preceding embodiments. One end of the bending portion is connected to the tip head 100, and the other end is connected to the insertion tube.

[0030] The endoscope tip device of this application has good thermal conductivity, which helps to improve the comfort and safety during endoscope use.

[0031] In an optional embodiment, an inner cavity communicating with the mounting groove 140 is provided within the bent portion along the axial direction of the bent portion. A heat-conducting element 400 is disposed within the inner cavity. One end of the heat-conducting element 400 is connected to the tip head seat, and the other end extends out of the inner cavity. The structure of the heat-conducting element 400 is as follows: Figure 4 As shown, its presence can conduct heat contained in the tip mount 100 away, which is beneficial to reducing the temperature of the tip mount 100. In addition, the inner cavity is connected to the mounting groove 140 through a through hole, which facilitates the passage of wires 310 and other wires connected to the camera system 200 and the light source 300.

[0032] In an optional embodiment, the heat-conducting element 400 is selected from at least one of oxygen-free copper wire, gold wire, silver wire and aluminum wire, and has good thermal conductivity, which is beneficial to reducing the temperature of the tip head 100.

[0033] It should be noted that the heat-conducting element 400 in this application can be provided as one or multiple; in order not to affect the bending ability of the bending part, the heat-conducting element 400 is preferably made of a material with good thermal conductivity and deformability, and the shape can be filament, sheet, etc., preferably filament; for example, the heat-conducting element 400 can include two or more heat-conducting wires, which are arranged sequentially along the circumference of the snake bone 500. Preferably, the heat-conducting wires are evenly distributed around the axis of the snake bone 500, which is beneficial to keep the temperature of the tip head seat 100 relatively uniform.

[0034] In an optional embodiment, the curved portion includes a snake bone 500 and a snake bone support structure, as shown in this application. Figure 5 As shown, it is a flexible tubular metal structure, and the snake bone support structure can adjust the bending shape of the snake bone 500.

[0035] In an optional embodiment, the snake-bone support structure includes a support wire 520 and a mesh sleeve 510 arranged along the direction of the snake bone 500, such as... Figure 6 As shown, the snake bone 500 is provided with a threading groove, and two or more threading grooves are arranged sequentially along the axial direction of the snake bone 500. The support wire 520 passes through the threading groove in sequence, and the net sleeve 510 is sleeved on the outside of the snake bone 500.

[0036] There can be one or more support wires 520. The support wires 520 can be steel wires. For example, the support wires 520 can include two or more steel wires. The two or more steel wires are arranged sequentially along the circumference of the snake bone 500. Preferably, the steel wires are evenly distributed around the snake bone 500, which helps to provide a relatively uniform support force for the snake bone 500. The main function is to adjust the bending shape of the snake bone 500.

[0037] Because the snake bone 500 is formed by the movable connection of multiple "joints", gaps are generated at the joints, especially when the joints are bent. Therefore, a sleeve is placed on the outside of the snake bone 500 as follows: Figure 6 The mesh sleeve 510 shown can improve the smoothness of the outer surface of the snake bone 500, which helps reduce resistance when the curved part moves in the body, while improving comfort.

[0038] In alternative implementations, such as Figure 7 As shown, the instrument channel 130 is connected to a forceps tube 600 for instruments to pass through. Since the tip head 100 is made of graphene-copper composite material, the forceps tube 600 is usually a non-metallic flexible tube. In order to facilitate the connection between the tip head 100 and the forceps tube 600, a connecting tube 610 is provided in some embodiments. One end of the connecting tube 610 is fixed to the instrument channel 130, and the other end is fixed to the forceps tube 600. The connecting tube 610 can be made of stainless steel.

[0039] For example, the connecting tube 610 can be assembled onto the tip head 100 by means of interference fit or other means, such as being assembled into the instrument channel 130 of the tip head 100, and a limiting device is provided to ensure the stable connection of the connecting tube 610.

[0040] In an optional embodiment, the outer side of the curved portion is wrapped with an elastic sleeve 700, which helps to reduce friction and improve comfort.

[0041] In an optional embodiment, a tip head shell 800 is also sleeved on the outside of the tip head seat 100, and the tip head shell 800 can be made of plastic.

[0042] In an optional embodiment, the surfaces of the snake bone 500, the mesh sleeve 510, and the heat-conducting component 400 are coated with graphene, which can increase lubricity, reduce frictional resistance, and improve comfort.

[0043] The present invention also provides an endoscope, including the endoscope tip device as described in any of the foregoing embodiments, wherein the endoscope tip device is sequentially connected to an insertion tube and an endoscope handle.

[0044] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0045] Example 1 This embodiment provides an endoscope tip mount 100 made of graphene-copper composite material, the specific structure of which is as follows: Figure 1 As shown. The graphene-copper composite material comprises alternating copper layers 120 and graphene layers 110. The graphene is formed on the copper layer 120 by chemical vapor deposition, resulting in a single-layer graphene-copper composite material. The parameters of the chemical vapor deposition include temperature: 1025℃±25℃, pressure: 200Pa±15Pa, and time: 900s±30s. Multiple single-layer graphene-copper composite materials are placed flat in a vacuum hot press mold. The mold is evacuated to a pressure of -98KPa to -101.325KPa. A pressure of 10MPa is continuously applied to both ends of the mold, while the temperature is maintained at 850℃ for 30 minutes, ultimately yielding the graphene-copper composite material.

[0046] In the tip head 100, the heat flow is parallel to the interface between the copper layer 120 and the graphene layer 110; the tip head 100 includes an instrument channel 130 and a mounting groove 140 for mounting the camera system 200 and the light source 300, and the mounting groove 140 is provided with a through hole for the wire 310 to pass through.

[0047] A schematic diagram of the graphene-copper composite material used in this embodiment is shown below. Figure 1As shown, it includes alternating layers of copper 120 and graphene 110, and the sample image is shown below. Figure 8 As shown; the morphology test results of the graphene-copper composite material are as follows. Figure 9 The testing standard is GB / T 33834-2017, and the testing equipment is an S-3400N scanning electron microscope. Figure 9 As can be seen, the graphene-copper composite material exhibits a "layered morphology". This is because graphene is "grown" on copper through chemical vapor deposition (CVD) during the material preparation process. After repeated processes, a multilayer graphene / copper composite material is finally produced.

[0048] The scanning electron microscopy (SEM) energy dispersive spectroscopy (EDS) results of the graphene-copper composite material are as follows: Figure 10 The testing standard is GB / T 17359-2023, from... Figure 10 The results show the proportions of copper, oxygen, and carbon in the graphene-copper composite material. Copper accounts for 83.530% atomically and 95.692% by mass, carbon for 6.154% atomically and 1.333% by mass, and oxygen for 10.316% atomically and 2.975% by mass. The proportion of copper is significantly higher than that of oxygen and carbon. This is because copper, as the substrate, constitutes a large proportion during the preparation of the graphene-copper composite material, while graphene, as the reinforcement, constitutes a smaller proportion. Since metallic copper undergoes an oxidation reaction with oxygen in the air, an energy dispersive spectroscopy (EDS) spectrum of oxygen is observed in the scanning electron microscope (SEM) image.

[0049] Example 2 This embodiment provides an endoscope tip device, including the tip seat 100 described in embodiment 1, a curved portion, and a camera system 200 and a light source 300 mounted on the tip seat 100. The tip seat 100 is provided with a tip shell 800 made of plastic material. The bent portion is connected at one end to the tip head 100 and at the other end to the insertion tube. Specifically, it includes a snake-bone 500 support structure and a snake-bone 500 with an inner cavity communicating with the mounting groove 140. The inner cavity is arranged along the axial direction of the snake-bone 500, and contains five oxygen-free copper wires with a specification of φ0.18mm*300mm. One end of each oxygen-free copper wire is connected to the tip head, and the other end extends out of the inner cavity. The snake-bone 500 support structure includes five support wires arranged along the direction of the snake-bone 500. 20 and a mesh sleeve 510, the snake bone 500 is provided with a threading groove, two or more of the threading grooves are arranged sequentially along the axis of the snake bone 500, the support wire 520 passes through the threading groove in sequence, the mesh sleeve 510 is sleeved on the outside of the snake bone 500, and the outside of the mesh sleeve 510 is also wrapped with a rubber sleeve; a stainless steel connecting tube 610 is fixed on the instrument channel 130 of the tip head seat 100, and the end of the connecting tube 610 away from the instrument channel 130 is fixed to the forceps tube 600.

[0050] The assembly method of the endoscope tip device in this embodiment specifically includes the following steps: 1. Place the camera system 200 and the light source 300 in the mounting groove 140 of the tip head 100 and bond them to the tip head 100.

[0052] 3. Graphene is coated on the surfaces of snake bone 500, mesh sleeve 510, and oxygen-free copper wire, except for the welding area, to increase lubricity and reduce frictional resistance.

[0053] 4. Pass one end of the steel wire through the pre-reserved groove of the snake bone 500 and weld it to the end of the snake bone 500 near the tip head seat 100 for fixation.

[0055] 6. Pass the oxygen-free copper wire through the inner cavity of the snake bone 500 and fix it to the tip head seat 100 by welding.

[0058] 9. Connect the end of the bent part away from the tip head seat 100 to the end of the insertion tube, and extend the oxygen-free copper wire into the insertion tube.

[0059] 10. The rubber sleeve is installed on the outside of the mesh sleeve 510.

[0060] Example 3 This embodiment provides an endoscope tip device, which differs from Embodiment 2 only in that it does not include oxygen-free copper wire.

[0061] Comparative Example 1 This comparative example provides an endoscope tip device, which differs from Embodiment 3 only in that the tip holder 100 and the tip shell 800 are integrally formed and are made of plastic.

[0062] Comparative Example 2 This comparative example provides an endoscope tip device, which differs from Example 3 only in that the tip holder 100 is made of a different material. In this comparative example, the preparation method of the composite material used in the tip holder 100 includes: mixing a material containing copper powder and graphene powder by mechanical stirring through a spiral device, and then producing a graphene copper composite material by cold pressing, thereby obtaining a graphene copper composite material with the same composition as Example 2 but a different structure.

[0063] Comparative Example 3 This comparative example provides an endoscope tip device, which differs from Embodiment 3 only in that, in the tip holder 100, the heat flow is perpendicular to the interface between the copper layer 120 and the graphene layer 110, that is, the heat is conducted between the layers.

[0064] Comparative Example 4 This comparative example provides an endoscope tip device, which differs from Example 3 only in that the tip holder 100 is made of a different material. In this comparative example, the composite material used for the tip holder 100 includes a copper rod matrix and a graphene coating on the surface of the copper rod matrix. Specifically, a slurry containing graphene and solvent is coated on the copper rod matrix and then dried to obtain a graphene-copper composite material with the same composition as Example 2 but a different structure.

[0065] The endoscope tip device in each of the above embodiments and comparative examples was assembled onto the endoscope. Under an environment of 25°C, the camera system 200 and the light source 300 were turned on and the timing was started. After 15 minutes, the temperature of the tip holder 100 was tested. The test results are shown in Table 1.

[0066] Table 1

[0067] The endoscope tip devices of Example 2 and Comparative Example 1 were assembled onto the endoscope. In an environment of 25°C, the camera system 200 and the light source 300 were turned on, and the images captured by the endoscope were observed on a monitor. Antistatic tests were performed on the tip and biopsy port, respectively. The test results are shown in Table 2.

[0068] Table 2

[0069] As can be seen from the comparison of Embodiments 2-3 and Comparative Example 1, the use of the endoscope tip mount 100 in this application in an endoscope is beneficial to reducing the tip temperature and improving the antistatic performance of the tip, thereby improving the comfort and safety during the use of the medical endoscope. Furthermore, when the endoscope tip mount 100 in this application is connected to an oxygen-free copper wire, the heat of the tip mount 100 can be further reduced.

[0070] As can be seen from Examples 3 and Comparative Examples 2 and 4 of this application, the temperature of the endoscope tip 100 is related to the structure of the graphene-copper composite material.

[0071] As can be seen from Embodiment 3 and Comparative Example 3 of this application, the temperature of the endoscope tip mount 100 is related to the direction of the graphene-copper composite material used. In the tip mount 100, it is more conducive to reducing the tip temperature when the heat flow is parallel to the interface between the copper layer 120 and the graphene layer 110.
