[0025] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] Please see Figures 1 to 3 , Figure 1 This is an assembly drawing of an endoscope system according to an embodiment of this application. Figure 2 This is a cross-sectional view of an endoscope system provided in one embodiment of this application. Figure 3 yes Figure 2 The endoscope system shown is partially magnified at point A.

[0027] This application provides an endoscope system 1000, which includes an endoscope assembly 100 and an endoscope host 300. The endoscope assembly 100 is pluggably mounted to the endoscope host 300 to assemble the endoscope system 1000. The endoscope assembly 100 can enter a target organ or target tissue through a natural opening or a small incision to observe the condition of the target organ or target tissue. The endoscope host 300 can present real-time images of the target organ or target tissue to medical personnel via a display device, allowing medical personnel to observe the condition of the target organ or target tissue in real time.

[0028] In some embodiments, the endoscope host 300 has a zoom function, allowing medical personnel to observe fine structures in target tissues or organs by adjusting the magnification of the endoscope host 300, thus enabling more accurate assessment of the condition of the target tissues or organs. The endoscope host 300 also has a light source control function, allowing medical personnel to adjust the brightness, color temperature, and illumination direction of the light source, enabling the endoscope system 1000 to be flexibly applied in different usage environments. The endoscope host 300 also has an image transmission function, enabling it to transmit acquired images or videos to other devices for remote application of the endoscope system 1000. The endoscope host 300 can also store acquired images or videos for later playback and review.

[0029] It is understood that in some other embodiments, depending on the application needs of the endoscope system 1000, the endoscope system 1000 may include only the endoscope assembly 100; or, the endoscope system 1000 may include only the endoscope host 300, and this application does not limit this.

[0030] Please see Figures 1 to 7 , Figure 4 This application provides a partial assembly of a lens assembly according to an embodiment. Figure 1 , Figure 5 This application provides a partial assembly of a lens assembly according to an embodiment. Figure 2 , Figure 6 This is a cross-sectional view of a lens assembly provided in one embodiment of this application. Figure 7 yes Figure 6 A partial method diagram of the lens assembly at point B.

[0031] This application provides an endoscope assembly 100 that can enter a target organ or target tissue through a natural opening or a small incision to observe the condition of the target organ or target tissue.

[0032] The endoscope assembly 100 includes a main body 110, a light guide 120, and a power receiver 130. The main body 110 includes a first end 110a and a second end 110b disposed opposite each other along the axial direction of the endoscope assembly 100. The first end 110a is used for insertion and connection with the endoscope host 300, and the second end 110b is used for entering the target organ or target tissue. The light guide 120 passes through the main body 110 and exposes the first end 110a. The light guide 120 is used to receive a high-brightness, highly focused light beam emitted from the endoscope host 300, enabling the endoscope assembly 100 to perform illumination and imaging functions. The power receiver 130 is located outside the main body 110 and connects to the portion of the light guide 120 that exposes the first end 110a of the main body 110. The power receiving component 130 is electrically connected to the main body 110 to receive wireless power generated by the endoscope host 300 so that the endoscope assembly 100 can function normally.

[0033] The endoscope assembly 100 provided in this embodiment receives wireless power through its power receiving component 130, thus avoiding the need for physical contact between the endoscope assembly 100 and the endoscope host 300, enabling the endoscope assembly 100 to operate normally. This reduces frictional losses caused by physical contact in the electrical connection between the endoscope assembly 100 and the endoscope host 300, lowering the risk of poor contact and making the electrical connection and signal transmission between them more stable and reliable, thereby improving the operational stability of the endoscope assembly 100.

[0034] Please see Figure 1 , Figure 4 , Figure 5 and Figure 8 , Figure 8 This is an exploded view of an endoscope host provided in one embodiment of this application.

[0035] This application also provides an endoscope host 300, which is used to connect to the endoscope assembly 100. The endoscope host 300 includes a host body 310 and a power supply unit 320. The host body 310 is used to generate an emitted high-brightness, high-convergence light beam to enable the endoscope assembly 100 to perform illumination and imaging functions. The host body 310 is also used to generate image information of the target organ or target tissue acquired by the endoscope assembly 100. The power supply unit 320 is used to transmit wireless power. In one embodiment, the host body 310 has a mounting hole 311, and the endoscope assembly 100 is inserted into the mounting hole 311 of the host body 310. The power supply component 320 is disposed in the main body 310. The power supply component 320 and the power receiving component 130 are configured such that, when the endoscope assembly 100 is inserted into the mounting hole 311 of the main body 310, the radio energy emitted by the power supply component 320 can be received by the power receiving component 130 of the endoscope assembly 100, so that the endoscope main body 300 supplies power to the endoscope assembly 100, thereby enabling the endoscope assembly 100 to operate normally. The power supply component 320 and the power receiving component 130 utilize the principle of electromagnetic resonance coupling, achieving energy transmission through the resonant frequency matching of the power supply component 320 and the power receiving component 130. This enables radio transmission, avoids contact-based electrical transmission, and reduces frictional losses between the power supply component 320 and the power receiving component 130.

[0036] The endoscope host 300 provided in this embodiment wirelessly powers the power receiving component 130 of the endoscope assembly 100 via its power supply component 320. This avoids the need for a physical contact between the endoscope assembly 100 and the endoscope host 300, enabling the endoscope assembly 100 to operate normally. This reduces frictional losses caused by physical contact in the electrical connection between the endoscope assembly 100 and the endoscope host 300, lowering the risk of poor contact and making the electrical connection and signal transmission between them more stable and reliable, thus improving the operational stability of the endoscope host 300.

[0037] Please see Figure 1 , Figures 3 to 5 and Figures 8 to 10 , Figure 9 This is a partial assembly drawing of an endoscope host provided in one embodiment of this application. Figure 10 yes Figure 9 The diagram shown is an exploded view of the endoscope unit.

[0038] In one embodiment, the endoscope host 300 includes a host body 310, a power supply component 320, and a support ring 330. The support ring 330 is disposed within a mounting hole 311 of the host body 310 and has a through hole 331 for the endoscope assembly 100 to pass through, the through hole 331 communicating with the mounting hole 311. The power supply component 320 is annular and is sleeved outside the support ring 330, located between the inner sidewall of the mounting hole 311 and the outer sidewall of the support ring 330. After the endoscope assembly 100 is installed in the endoscope host 300, the power supply component 320 is sleeved outside the power receiving component 130, that is, the power supply component 320 and the power receiving component 130 are aligned in the radial direction of the endoscope assembly 100, and the power receiving component 130 is used to receive wireless power transmitted by the power supply component 320.

[0039] The endoscope host 300 provided in this embodiment wirelessly supplies power to the power receiving component 130 of the endoscope assembly 100 via its power supply component 320. This avoids the electrical connection between the endoscope assembly 100 and the endoscope host 300 formed through physical contact, reducing frictional losses caused by physical contact and lowering the risk of poor contact. This makes the electrical connection and signal transmission between the endoscope assembly 100 and the endoscope host 300 more stable and reliable, improving the operational stability of the endoscope host 300. Furthermore, since the power supply component 320 is sleeved outside the power receiving component 130, the structural space occupied by the power supply component 320 and the power receiving component 130 is reduced, thus minimizing the contact area between the endoscope assembly 100 and the endoscope host 300. Furthermore, aligning the power supply component 320 and the power receiving component 130 in the radial direction of the endoscope assembly 100 improves the efficiency of radio transmission between them. Also, since the power supply component 320 is located between the inner wall of the mounting hole 311 and the outer wall of the support ring 330, it prevents direct contact between the endoscope assembly 100 and the power supply component 320 during insertion into the endoscope host 300. This avoids frictional damage between the endoscope assembly 100 and the power supply component 320, thus extending the service life of both the power supply component 320 and the endoscope host 300.

[0040] Please see Figure 1 , Figure 3 and Figures 8 to 10In one specific embodiment, a limiting portion 332 is provided on the support ring 330 of the endoscope host 300. The limiting portion 332 is located on the peripheral sidewall of the support ring 330 and is used to restrict the movement of the power supply component 320 relative to the support ring 330. A connecting position is provided on the limiting portion 332, which is used to connect with a connector on the inner sidewall of the mounting hole 311, so that the support ring 330 can be fixedly disposed within the mounting hole 311.

[0041] The endoscope host 300 provided in this embodiment restricts the power supply component 320 from moving along the axial direction of the endoscope assembly 100 on the support ring 330 by setting a limiting part 332 on the support ring 330, so that the power receiving component 130 and the power supply component 320 are kept aligned in the radial direction of the endoscope assembly 100, and the stability of radio transmission between the power receiving component 130 and the power supply component 320 is better.

[0042] Please see Figure 1 , Figure 3 , Figure 4 and Figure 8 In the endoscope system 1000 provided in this embodiment, the power receiving component 130 of the endoscope assembly 100 has a ring coil structure, and the power supply component 320 of the endoscope host 300 has a ring coil structure. When the endoscope assembly 100 is inserted into the endoscope host 300, the power supply component 320 is sleeved outside the power receiving component 130, and the power supply component 320 and the power receiving component 130 are aligned in the radial direction of the endoscope assembly 100. This reduces the structural space occupied by the power supply component 320 and the power receiving component 130 in the axial and radial directions of the endoscope assembly 100, thereby reducing the contact area between the endoscope assembly 100 and the endoscope host 300.

[0043] It is understood that in some other embodiments, the power receiving component 130 of the endoscope assembly 100 may be in the form of a planar structure or a cylindrical structure, etc., and the power supply component 320 of the endoscope host 300 may be in the form of a planar structure or a cylindrical structure, etc., as long as the power receiving component 130 can receive the radio waves generated by the power supply component 320, this application does not impose any restrictions on this.

[0044] Please see Figures 1 to 5 and Figure 7In one embodiment, the lens assembly 100 includes a main body 110, a light guide 120, a power receiving component 130, and a mounting portion 140. The mounting portion 140 is sleeved on the portion of the light guide 120 that exposes the first end 110a of the main body 110. The mounting portion 140 is located outside the main body 110, and the power receiving component 130 is sleeved outside the mounting portion 140, i.e., the mounting portion 140 is sandwiched between the light guide 120 and the power receiving component 130. The mounting portion 140 is preferably made of a softer material to reduce damage to the light guide 120 during assembly. The mounting portion 140 may be an insulating structure, for example, a plastic structure, to reduce interference between the power receiving component 130 and the light guide 120.

[0045] The mirror assembly 100 provided in this embodiment is clamped between the light guide 120 and the power receiving component 130 by the mounting part 140. This can avoid direct contact between the power receiving component 130 and the light guide 120, reduce the thermal impact between the power receiving component 130 and the light guide 120, and help improve the working stability of the light guide 120 and the power receiving component 130.

[0046] Please see Figures 1 to 5 and Figure 7 In one embodiment, the lens assembly 100 includes a main body 110, a light guide 120, a power receiver 130, a mounting portion 140, and a protective shell 150. The protective shell 150 is located outside the main body 110 and covers the power receiver 130 and the mounting portion 140. The light guide 120 passes through the protective shell 150, forming a structure in which the light guide 120, the mounting portion 140, the power receiver 130, and the protective shell 150 are sequentially arranged from the inside out.

[0047] The endoscope assembly 100 provided in this embodiment is sequentially fitted from the inside out by a light guide 120, a mounting part 140, a power receiving part 130, and a protective shell 150. The protective shell 150 can provide physical protection for the power receiving part 130, avoiding frictional damage between the power receiving part 130 and the endoscope host 300 during the process of inserting the endoscope assembly 100 into the endoscope host 300, which is beneficial to improving the assembly quality between the endoscope assembly 100 and the endoscope host 300.

[0048] Please see Figures 1 to 5 and Figure 7In one specific embodiment, the mounting portion 140 of the lens assembly 100 includes a first portion 141 and a second portion 142 connected along a first direction (the axial direction of the lens assembly 100). The first portion 141 is closer to the first end 110a of the main body portion 110 relative to the second portion 142. In a second direction perpendicular to the first direction (the radial direction of the lens assembly 100), the second portion 142 is larger than the first portion 141, and the power receiving component 130 is sleeved outside the first portion 141. The protective shell 150 of the lens assembly 100 has a receiving cavity 151, in which the first portion 141 and the power receiving component 130 are housed. The receiving cavity 151 includes a first opening 1511 and a second opening 1512 disposed opposite each other along the axial direction of the lens assembly 100. The periphery of the first opening 1511 seals against the end face of the first end 110a of the main body portion 110, and the periphery of the second opening 1512 seals against the side of the second portion 142 closest to the first portion 141. Thus, the power receiving component 130 is sealed within the main body 110, mounting portion 140, and protective shell 150 of the mirror assembly 100. The periphery of the first opening 1511 and the end face of the first end 110a of the main body 110 can be sealed using a sealing ring or sealant. Similarly, the periphery of the second opening 1512 and the side of the second portion 142 closest to the first portion 141 can be sealed using a sealing ring or sealant. This application does not impose any limitations on this aspect.

[0049] The endoscope assembly 100 provided in this embodiment requires frequent cleaning and disinfection. By sealing the power receiving component 130 with the main body 110, mounting part 140, and protective shell 150 of the endoscope assembly 100, it is possible to prevent cleaning agents and disinfectants from coming into contact with the power receiving component 130 of the endoscope assembly 100. This prevents the cleaning agents and disinfectants from corroding the surface of the power receiving component 130 of the endoscope assembly 100, which could lead to the failure of the power receiving component 130. This helps to ensure the quality of the power receiving component 130 during the cleaning and disinfection process, thereby improving the stability of the wireless connection and signal transmission between the power receiving component 130 of the endoscope assembly 100 and the power supply component 320 of the endoscope host 300. Moreover, since the endoscope assembly 100 has high requirements for cleaning and disinfection, by sealing the power receiving component 130 and the wireless connection between the power receiving component 130 and the power supply component 320 of the endoscope host 300, it is possible to avoid the power receiving component 130 being corroded by cleaning agents and disinfectants, which would require the power receiving component 130 to be replaced, thus helping to reduce the operating cost of the endoscope assembly 100.

[0050] Please see Figures 1 to 5 and Figure 7In a more specific embodiment, the light guide 120 of the lens assembly 100 passes through the first portion 141 and the second portion 142 of the mounting portion 140, with the light guide 120 exposed on the side of the second portion 142 away from the first portion 141. The lens assembly 100 also includes a seal 160, which seals between the light guide 120 and the second portion 142 of the mounting portion 140. The seal 160 can be a sealing ring during the assembly of the mounting portion 140 and the light guide 120, or it can be a sealant after the mounting portion 140 and the light guide 120 are assembled; this application does not limit this.

[0051] The endoscope assembly 100 provided in this embodiment requires frequent cleaning and disinfection. By sealing the gap between the light guide 120 and the second part 142 of the mounting part 140 with the sealing member 160, cleaning agents and disinfectants can be prevented from seeping into the gap between the light guide 120 and the second part 142 of the mounting part 140. This prevents the cleaning agents and disinfectants from coming into contact with the power receiving component 130 of the endoscope assembly 100, thereby preventing the cleaning agents and disinfectants from corroding the surface of the power receiving component 130 of the endoscope assembly 100 and causing the power receiving component 130 to fail. This helps to ensure the quality of the power receiving component 130 during the cleaning and disinfection process, and further improves the stability of the wireless connection and signal transmission between the power receiving component 130 of the endoscope assembly 100 and the power supply component 320 of the endoscope host 300.

[0052] In some other embodiments, the lens assembly 100 may include a main body 110, a light guide 120, a power receiver 130, a mounting portion 140, and a protective shell 150. The protective shell 150 is located outside the main body 110, covering the power receiver 130 and the mounting portion 140. The light guide 120 passes through the protective shell 150, forming a structure in which the light guide 120, mounting portion 140, power receiver 130, and protective shell 150 are sequentially arranged from the inside out. The protective shell 150 has a receiving cavity 151, in which the power receiver 130 and at least a portion of the mounting portion 140 are accommodated. The receiving cavity 151 includes a first opening 1511 and a second opening 1512. The periphery of the first opening 1511 is in sealed contact with one end of the mounting portion 140, and the periphery of the second opening 1512 is in sealed contact with the other end of the mounting portion 140, so that the space formed by the mounting portion 140 and the protective shell 150 can seal the power receiving component 130 of the mirror assembly 100.

[0053] Understandably, the periphery of the first opening 1511 can be in sealing contact with the peripheral sidewall of one end of the mounting portion 140, or it can be in sealing contact with the end face of one end of the mounting portion 140; this application does not impose any limitation on this. The periphery of the second opening 1512 can be in sealing contact with the peripheral sidewall of the other end of the mounting portion 140, or it can be in sealing contact with the end face of the other end of the mounting portion 140; this application does not impose any limitation on this.

[0054] The endoscope assembly 100 provided in this embodiment requires frequent cleaning and disinfection. By sealing the power receiving component 130 with the mounting part 140 and the protective shell 150 of the endoscope assembly 100, contact between the cleaning agent and the power receiving component 130 of the endoscope assembly 100 can be prevented. This prevents the cleaning agent and disinfectant from corroding the surface of the power receiving component 130 of the endoscope assembly 100, which could lead to the failure of the power receiving component 130. This helps to ensure the quality of the power receiving component 130 during the cleaning and disinfection process, thereby improving the stability of the wireless connection and signal transmission between the power receiving component 130 of the endoscope assembly 100 and the power supply component 320 of the endoscope host 300. Moreover, since the endoscope assembly 100 has high requirements for cleaning and disinfection, by sealing the power receiving component 130 and the wireless connection between the power receiving component 130 and the power supply component 320 of the endoscope host 300, it is possible to avoid the power receiving component 130 being corroded by cleaning agents and disinfectants, which would require the power receiving component 130 to be replaced, thus helping to reduce the operating cost of the endoscope assembly 100.

[0055] Please see Figure 1 , Figure 3 , Figure 5 and Figure 8 In one embodiment, the peripheral wall of the main body 110 of the endoscope assembly 100 has a first limiting step 111, which abuts against the endoscope host 300 to limit the depth of insertion of the endoscope assembly 100 into the endoscope host 300. Correspondingly, the inner sidewall of the mounting hole 311 of the endoscope host 300 has a second limiting step 312, which abuts against the endoscope assembly 100 to limit the depth of insertion of the endoscope assembly 100 into the mounting hole 311. In other words, when the endoscope assembly 100 is inserted into the endoscope host 300, the first limiting step 111 of the endoscope assembly 100 abuts against the second limiting step 312 of the endoscope host 300. At this time, the power receiving component 130 of the endoscope assembly 100 and the power supply component 320 of the endoscope host 300 are arranged opposite each other in the radial direction of the endoscope assembly 100.

[0056] The endoscope assembly 100 provided in this embodiment abuts against the endoscope host 300 via a first limiting step 111 of the endoscope assembly 100 and a second limiting step 312 of the endoscope host 300. This allows the power receiving component 130 of the endoscope assembly 100 and the power supply component 320 of the endoscope host 300 to be arranged opposite each other in the radial direction of the endoscope assembly 100. This prevents the power receiving component 130 of the endoscope assembly 100 and the power supply component 320 of the endoscope host 300 from being misaligned in the radial direction of the endoscope assembly 100 due to excessive or insufficient insertion depth of the endoscope assembly 100 in the endoscope host 300. This is beneficial for improving the assembly efficiency of the endoscope assembly 100 and the endoscope host 300.

[0057] Please see Figure 1 , Figure 3 , Figure 5 and Figure 8 In one embodiment, the peripheral wall of the main body 110 of the endoscope assembly 100 has a limiting groove 112, which engages with the endoscope host 300 to prevent the endoscope assembly 100 from falling out of the endoscope host 300. Correspondingly, the inner sidewall of the mounting hole 311 of the endoscope host 300 has an elastic limiting protrusion 313, which engages with the endoscope assembly 100 to prevent the endoscope assembly 100 from falling out of the mounting hole 311. In other words, when the endoscope assembly 100 is inserted into the endoscope host 300, the limiting groove 112 of the endoscope assembly 100 engages with the elastic limiting protrusion 313 of the endoscope host 300.

[0058] The endoscope assembly 100 provided in this embodiment engages with the elastic limiting protrusion 313 of the endoscope host 300 through the limiting groove 112 of the endoscope assembly 100, so that the stability of the endoscope assembly 100 after being inserted into the endoscope host 300 is better, which is conducive to ensuring the radio connection and signal transmission between the power receiving component 130 of the endoscope assembly 100 and the power supply component 320 of the endoscope host 300.

[0059] Understandably, in some other embodiments, the limiting groove 112 can be disposed on the inner sidewall of the mounting hole 311 of the endoscope host 300, and the elastic limiting protrusion 313 can be disposed on the peripheral sidewall of the main body 110 of the endoscope assembly 100. After the elastic limiting protrusion 313 cooperates with the limiting groove 112, the stability of the endoscope assembly 100 after being inserted into the endoscope host 300 can also be better. This application does not limit this.

[0060] In this embodiment, there are multiple limiting grooves 112, which are sequentially and spaced apart on the peripheral wall of the main body 110 around the axial direction of the endoscope assembly 100. There are also multiple elastic limiting protrusions 313, which are sequentially and spaced apart on the inner sidewall of the mounting hole 311 around the axial direction of the endoscope assembly 100. When the endoscope assembly 100 is inserted into the endoscope host 300, each limiting groove 112 corresponds to one elastic limiting protrusion 313. This further improves the stability of the endoscope assembly 100 after insertion into the endoscope host 300.

[0061] The above are some embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.
