[0003] Medical electronic endoscopes can be divided into soft endoscopes and hard endoscopes. Currently, the soft endoscope systems and hard endoscope systems on the market are independent of each other and incompatible. Among them, due to the inconsistency of the video signal types and control signals, the video processing methods are also inconsistent, the interface structure is incompatible and other reasons, the processor of the soft endoscope system is not compatible with the scope body of the hard endoscope, and the processor of the hard endoscope system is not compatible with the scope body of the soft endoscope.

[0004] The interface between the body of a medical electronic endoscope and the endoscope processor requires high reliability and good shielding performance, and also has high requirements for plug-in life. Due to the inconsistency in the use of hard and soft endoscopes, the body of the soft endoscope needs to be immersed and disinfected as a whole. Therefore, the interface of the soft endoscope body needs to meet the IPX7 waterproof requirements; however, the hard endoscope does not need to be immersed and disinfected, so it does not need to meet the waterproof requirements. The two have inconsistent requirements for interface connectors, and the connectors of the soft endoscope system and the hard endoscope system are usually not set up for compatible matching. The above situations have led to incompatibility between the use of soft and hard endoscopes, causing inconvenience in the use of endoscopes.

[0050] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0051] The core of the present application is to provide an endoscope electrical signal connection device, which is used to realize the connection and transmission of endoscope electrical signals. It can be applicable to two different types of endoscopes, hard endoscopes and soft endoscopes. It can effectively realize a set of endoscope processors to adapt to multiple endoscope body types, thereby improving the compatibility and versatility of the endoscope system and reducing the cost of the equipment.

[0052] Another core of the present application is to provide an endoscope system including the above-mentioned endoscope electrical signal connection device.

[0053] Please refer to Figure 1 The present application provides an endoscope electrical signal connection device for realizing the connection between the endoscope body side and the endoscope processor side, and structurally comprises a plug 1 connected to the endoscope body, and the plug 1 is used to be plugged into a socket 2 provided on the endoscope processor. The endoscope processor can be specifically an endoscope image processor.

[0054] Please refer to Figure 2 and Figure 3 The plug 1 includes an interface board 131 and a waterproof and corrosion-resistant shell 11 arranged outside the interface board 131.

[0055] The interface board 131 is electrically connected to the endoscope body, and a plurality of waterproof and corrosion-resistant conductive terminals 132 are provided at the front end of the interface board 131. The conductive terminals 132 can be conductive contacts with a gold-plated surface, such as gold fingers, wherein the gold-plated contacts are also waterproof and corrosion-resistant because gold has a strong oxidation resistance.

[0056] The waterproof and corrosion-resistant housing 11 is sealed and wrapped around the outside of the interface board 131, and the conductive terminal 132 is at least partially exposed from the waterproof and corrosion-resistant housing 11 to be electrically connected to the socket 2 to achieve transmission of electrical signals. Specifically, the waterproof and corrosion-resistant housing 11 can completely seal and wrap the interface board 131 except for the position where the conductive terminal 132 is formed, so that the waterproof and corrosion-resistant housing 11 can effectively provide waterproof and corrosion-resistant protection for other circuit structures formed on the interface board 131 except for the conductive terminal 132.

[0057] When the endoscope body connected to the endoscope electrical signal connection device is a hard endoscope, the interface board 131 is a non-waterproof or non-corrosion-resistant substrate board;

[0058] When the endoscope body connected to the endoscope electrical signal connection device is a flexible endoscope, the interface board 131 is a waterproof and corrosion-resistant substrate board.

[0059] In this embodiment, the circuit structure formed on the interface board 131, except for the conductive terminal 132, can be effectively protected from water and corrosion by the waterproof and corrosion-resistant shell 11, and the conductive terminal 132 itself also has waterproof and corrosion-resistant properties; therefore, the waterproofness and / or corrosion resistance of the plug 1 as a whole mainly depend on the waterproofness and / or corrosion resistance of the interface board 131. Therefore, different interface boards 131 can be set according to different connected mirror bodies. When used as the plug 1 of a hard mirror, the commonly used PCB substrate board can meet the use requirements of the hard mirror, so the interface board 131 can use a non-waterproof or non-corrosion-resistant substrate board to reduce the cost; when used as the plug 1 of a soft mirror, because the soft mirror needs to be cleaned and disinfected, the waterproof and corrosion-resistant properties of the plug 1 are required to be higher, so the interface board 131 can use a waterproof and corrosion-resistant substrate board to avoid the water immersion and corrosion caused by the soft mirror cleaning and disinfection process.

[0060] In this embodiment, by setting the plug 1 as an external waterproof and corrosion-resistant structure and setting different interface boards 131 for different scope types, the plugs 1 of the hard scope and the soft scope can be unified in structure so as to be plugged into the same socket 2 on the endoscope processor side.

[0061] The endoscope electrical signal connection device provided in the present application unifies the structure of the plug 1, and only the interface board 131 needs to be changed to achieve adaptation to hard mirrors and soft mirrors, thereby meeting the needs of soft mirror disinfection and achieving cost control for hard mirrors without disinfection requirements, thereby facilitating design and production; at the same time, due to its unified structure, it can be adapted to the same type of socket, so as to unify the connection structure on the endoscope processor side, thereby simplifying the setting and layout on the endoscope processor side.

[0062] In view of the scheme of setting different interface plates 131 for the above-mentioned different types of mirror bodies, different materials of the interface plates 131 can be selected in order to further control the structural cost.

[0063] In the plug 1 applicable to the hard mirror, the non-waterproof or non-corrosion-resistant substrate board can be specifically a FR-4 substrate board or a FR-5 substrate board. FR-4 substrate boards include common insulating boards, epoxy boards, and epoxy resin boards, etc., which usually have a certain hardness and have characteristics such as flame retardancy. At the same time, they have a certain water absorption, so they can only be used in the hard mirror product environment. In addition, the gold finger process of FR-4 substrate boards is relatively mature and the price is relatively low. Applying them to hard mirrors that do not require waterproofing can save costs.

[0064] In the plug 1 applicable to the soft mirror, the waterproof and corrosion-resistant substrate plate may specifically include a plastic substrate plate or a PCB composite substrate plate. The plastic substrate plate and the PCB composite substrate plate have waterproof and corrosion-resistant effects. The interface board 131 is made of the above-mentioned material, which can prevent the part of the interface board 131 exposed to the waterproof and corrosion-resistant shell 11 from being immersed in water or corroded to produce structural changes. Of course, it can be understood that the above-mentioned materials are not the only options in this application, and similar materials can be selected according to actual conditions.

[0065] Specifically, the above-mentioned plastic substrate board can be formed by injection molding. After the injection molding operation is completed, one end of the conductive terminal 132 (i.e., the end used to connect to the socket 2) is exposed from the injection molding structure of the plastic substrate board, and the other end of the conductive terminal 132 is wrapped in the injection molding structure to be electrically connected to other circuit structures in the interface board 131.

[0066] The PCB composite substrate board may be a composite substrate board including two or more materials and having a low water absorption rate. For example, a composite substrate board including hydrocarbon / ceramic / glass cloth material has a water absorption rate of about one tenth of that of the FR-4 substrate board, and has the characteristics of corrosion resistance, and has a mechanical strength similar to that of the FR-4 substrate board, and can realize multiple plug-in and pull-out connections of the conductive terminal 132.

[0067] In order to further improve the waterproof and corrosion-resistant performance of the plug 1, the conductive terminal 132 can be a conductive terminal 132 that does not leak base copper, formed by a gold finger gold plating process of etching and wiring inside the PCB composite substrate board.

[0068] It should be noted that the traditional gold finger gold plating process is to set leads and main conductors at the front end of the conductive terminal 132, and connect them to the edge of the interface board 131 to achieve the connection of electrical functions. After gold plating, the leads are removed by wet film etching or hand tearing to obtain a conductive terminal 132 gold-plated on three sides. However, there is a part of the copper structure exposed at the front end, so that corrosion often occurs at the copper leakage position during the disinfection operation.

[0069] In order to avoid the problem of copper leakage at the front end, for the PCB composite substrate board, the lead is transferred to the board, for example, the end of the conductive terminal 132 and the lead connected to the end can be located in the PCB composite substrate board or in the pad, so as to realize the form of wiring inside the board, and then the lead inside the board is etched to remove the copper leakage hole caused by the lead at the front end of the conductive terminal 132, so as to obtain the conductive terminal 132 without base copper leakage, so that the conductive terminal 132 can be fully gold-plated. The above-mentioned wiring inside the board or setting the pad is a common setting, and the specific implementation can refer to the existing technology.

[0070] In this embodiment, the leads are adjusted to leads inside the board or inside the pad by means of internal leads of the interface board 131, so that a conductive terminal 132 without copper leakage is obtained after etching, and the conductive terminal 132 is fully gold-plated. The above method can improve the waterproof and corrosion resistance of the conductive terminal 132 and the interface board 131.

[0071] The above two embodiments achieve the waterproof and corrosion-resistant effect of the conductive terminal 132 in different ways. The interface board 131 obtained by reasonable combination based on the above material design, structural relationship or process mode belongs to the protection scope of this application.

[0072] Since the endoscope electrical signal connection device needs to be electrically connected to the endoscope body, the interface board 131 is connected to the endoscope body via the cable 12 to achieve the transmission of electrical signals between the endoscope body and the interface board 131 .

[0073] Specifically, a soldering pad electrically connected to the conductive terminal 132 is formed on the interface board 131, and various electronic components are welded on the soldering pad to form a related circuit structure on the interface board 131. One end of the cable 12 is connected to the soldering pad, and the other end is connected to the endoscope body.

[0074] The cable 12 includes a wire core 122, a shielding layer 121 and a rubber coating layer which are arranged in sequence from the inside to the outside, wherein the wire core 122 is welded to the soldering pad of the interface board 131 to be electrically connected to the circuit structure on the interface board 131; the shielding layer 121 is connected to the socket 2 through the waterproof and corrosion-resistant shell 11 to achieve suspended grounding of the shielding layer 121.

[0075] With respect to the structure of the waterproof and corrosion-resistant shell 11 mentioned above, the present application provides a specific embodiment, wherein the waterproof and corrosion-resistant shell 11 includes: a silicone shell 113 and a metal shielding structure 10.

[0076] The silicone shell 113 mainly seals and wraps the interface board 131 except for the exposed part of the conductive terminal 132, and the end of the cable 12 connected to the interface board 131, so as to provide waterproof and anti-corrosion protection for the wrapped area. The manufacturing process is sealed and injection-molded on the outside of the interface board 131, and the conductive terminal 132 is at least partially exposed at the front end of the silicone shell 113. The silicone shell 113 is injection-molded on the outside of the interface board 131 to form a full cover. The use of the silicone shell 113 can achieve a good waterproof effect. At the same time, the silicone has high stability and can also achieve a corrosion-resistant effect. The above-mentioned sealed injection molding refers to the coating of the interface board 131 by the injection molding structure, and no gaps are provided at the front end or the rear end for water to enter the interior. The above-mentioned silicone shell 113 can be made by injection molding of silicone after the interface board 131 and the metal shielding structure 10 are set.

[0077] The metal shielding structure 10 is used to connect the shielding layer 121 of the cable 12 and the socket 2 , and may specifically include: a metal shell 112 and a fixing member 111 .

[0078] The metal shell 112 is sleeved on the front end of the silicone shell 113 . The front end of the metal shell 112 is used to connect with the socket 2 , and the rear end of the metal shell 112 is embedded in the silicone shell 113 .

[0079] The fixing member 111 is disposed in the silicone shell 113 and is used to connect the metal shell 112 and the shielding layer 121 so that the shielding layer 121 is connected to the socket 2 .

[0080] Among them, Figure 4 As shown, the fixing member 111 includes a harness fixing clamp 1111 and a harness fixing seat 1112. One end of the harness fixing seat 1112 can be connected to the metal shell 112 by screw connection or the like, and the other end cooperates with the harness fixing clamp 1111 to clamp the shielding layer 121. The harness fixing clamp 1111 and the harness fixing seat 1112 are both conductive structures, so that the shielding layer 121 can be electrically connected to the socket 2 through the harness fixing clamp 1111, the harness fixing seat 1112 and the metal shell 112 to achieve a stable shielding effect.

[0081] In one embodiment, the shielding layer 121 of one end of the cable 12 used to connect the fixing member 111 is exposed from the rubber coating along the length direction of the cable 12 , so that the wire harness fixing clamp 1111 and the wire harness fixing seat 1112 cooperate to clamp the exposed shielding layer 121 .

[0082] In another embodiment, the shielding layer 121 and the wire core 122 at one end of the cable 12 used to connect the fixing member 111 are in a separated state, the shielding layer 121 is folded outward to the outside of the rubber coating layer, and the wiring harness fixing clamp 1111 clamps the folded shielding layer 121 on both sides of the wire core 122.

[0083] The shielding layer 121 is folded toward the location of the outer rubber layer, causing the rubber layer to overlap itself. Due to the elastic effect of the rubber layer itself, it has the function of driving the shielding layer 121 to reset. At the same time, the shielding layers 121 on both sides of the diameter direction of the wire core 122 are subjected to radial outward reset forces. At this time, the wire harness fixing clamp 1111 and the wire harness fixing seat 1112 cooperate to clamp the shielding layers 121 on both sides of the wire core 122. The reset force prevents the clamping force from directly acting on the wire core 122, thereby preventing the wire core 122 from being damaged.

[0084] In a specific embodiment, the plug 1 further includes a shielding cover 114 , which is disposed on the pad of the interface board 131 and is used to shield the circuit structure in the pad for signals.

[0085] Please refer to Figure 7 , wherein the shielding cover 114 is fixed on the interface board 131, and the portion covered by the shielding cover 114 is where the pad is located. Specifically, a positioning structure (such as a positioning hole) is provided on the periphery of the pad, and the shielding cover 114 can be positioned with the pad using the positioning structure and fixed to the pad by welding. In addition, it can be understood that in this embodiment, the interface board 131 is a double-sided circuit board, and accordingly, Figure 2 , Figure 4 or Figure 6 As shown, the shielding cover 114 may include two cover plates, which are respectively disposed on both sides of the interface board 131. In other embodiments, when the interface board 131 is a single-sided circuit board, only one shielding cover may be disposed on the side where the circuit structure is formed.

[0086] In addition, considering that the endoscope electrical signal connection device provided in the present application can be used for both hard and soft endoscopes, the structure of the interface board 131 can be adjusted to have a modular multiplexing structure so as to reduce structural changes accordingly.

[0087] Specifically, the conductive terminals 132 of the interface board 131 may include multiplexing terminals, which are terminals that can be shared by the soft mirror and the hard mirror, such as terminals for connecting power, buttons, and I2C signals of EEPROM, etc. Through multiplexing, the number of terminals is reduced, saving space and materials. In addition, to avoid signal conflicts, the conductive terminals 132 may also include dedicated terminals, which may include dedicated terminals for the soft mirror and dedicated terminals for the hard mirror, wherein the dedicated terminals for the soft mirror are used to transmit signals used independently by the soft mirror, and the dedicated terminals for the hard mirror are used to transmit signals used independently by the hard mirror.

[0088] In addition, other terminals may be provided in the conductive terminal 132 to provide a new signal interface for upgrading the endoscope processor, so that the old versions of the soft endoscope and the hard endoscope can continue to match and use the new version of the endoscope processor.

[0089] The endoscope electrical signal connection device provided in the above-mentioned embodiments includes a plug 1. Since it has the same external structure for hard endoscopes and soft endoscopes and only differs in the interface board 131, it can be fully adapted to the same socket 2 structure, thereby simplifying the design of the socket 2 and reducing the design and use costs.

[0090] In a specific embodiment, the endoscope electrical signal connection device also includes a socket 2, and the plug 1 can be plugged into the socket 2, the plug 1 is located on the endoscope body side, and the socket 2 is located on the endoscope processor side.

[0091] The socket 2 comprises a socket housing 22 , a connector female socket 23 and a metal member 21 .

[0092] The socket housing 22 is fixed to the insulating housing of the endoscope processor and is used for plugging and connecting with the metal housing 112 of the plug 1 .

[0093] The connector socket 23 is disposed on the socket housing 22 for connecting the conductive terminal 132 .

[0094] The metal member 21 is fixed to the socket housing 22 , and one end thereof is connected to the insulating housing of the endoscope processor.

[0095] When the socket shell 22 is plugged into the metal shell 112, the connector socket 23 is connected to the conductive terminal 132 to realize the transmission of electrical signals; at the same time, the other end of the metal part 21 contacts the metal shell 112 to connect the shielding layer 121 of the cable 12 to the insulating shell of the endoscope processor to achieve suspended grounding.

[0096] Specifically, please refer to Figure 5 , Figure 6 and Figure 8A socket panel 24 is disposed at the front end of the socket housing 22. The socket panel 24 and the socket housing 22 are used together to connect the metal shell 112 of the plug 1. The socket panel 24 can guide the insertion direction.

[0097] The connector female socket 23 is disposed in the middle of the socket housing 22, and a plug-in structure for plugging the conductive terminal 132 is disposed therein. The plug-in structure can connect the conductive terminal 132 with the internal circuit of the endoscope processor.

[0098] The metal part 21 can be a metal spring or a conductive structure with elastic force, one end of which abuts against the insulating shell of the endoscope processor, and the other end is bent toward the plug-in channel formed in the socket shell 22. Therefore, when the socket shell 22 is plugged into the metal shell 112, the bent part of the metal part 21 abuts against the outer surface of the metal shell 112. Under the elastic force of the metal part 21, a stable conductive connection can always be maintained between the metal part 21 and the metal shell 112.

[0099] The socket 2 provided in this embodiment can be adapted to the above-mentioned plug 1 and achieve a stable connection effect. For the above-mentioned plug 1 structure, the above-mentioned socket 2 can be used regardless of whether it is a hard lens or a soft lens.

[0100] Since the plug 1 needs to be adapted to a hard or soft mirror, the endoscope processor using the socket 2 during use can determine the type of the current mirror body through a preset structure or information when facing different mirror bodies, so as to facilitate the selection of different data collection methods and processing methods for different mirror body types. Specifically, the endoscope processor also includes an identification code processing device, and the socket 2 is communicatively connected to the identification code processing device, so that the identification code processing device obtains the identification code of the endoscope body connected to the socket 2 through the socket 2, and determines the mirror body type according to the identification code.

[0101] It should be noted that the identification code can be stored in the chip of the scope, or in the interface board 131 of the plug 1.
