Description

Technical Field

[0001] The present application relates to the field of medical device technology, and in particular to endoscope technology. Background Art

[0002] Endoscopic technology plays an increasingly important role in modern medical diagnosis and treatment, especially duodenoscopes are widely used in the diagnosis and treatment of digestive system diseases. However, traditional duodenoscopes still face some technical challenges in their design and use.

[0003] At present, in the distal seat structure of the insertion part of most reusable duodenoscopes, the forceps lifter and the end seat are usually connected together by pins, while the end seat cap and the end seat are adhered together. Although this design has a certain stability during use, it also brings a series of problems:

[0004] Infection risk: This fixed structure makes it very difficult to reprocess the duodenoscope. If it is not properly reprocessed, the patient's tissue or body fluids may remain on the device, which may then enter the body of another patient during the next use, causing cross infection.

[0005] Complex reprocessing: Due to the fixed nature of the structure, the cleaning and disinfection process becomes complicated and time-consuming. In particular, it is difficult to ensure thorough cleaning of some small gaps and joints, which not only increases the workload of medical institutions, but may also affect the efficiency of equipment use.

[0006] Operational limitations: In traditional designs, the operation of the forceps lifter is often limited by the structure, making it difficult to achieve precise and flexible control, which may affect the effectiveness of certain complex operations performed by doctors.

[0007] Sealing issues: Fixed structures may experience reduced sealing performance after long-term use, increasing the risk of contaminants entering the interior or liquid seeping in, affecting the normal use and life of the equipment.

[0008] High maintenance cost: Since it is difficult to disassemble, when a part of the equipment has a problem, it is often necessary to replace the entire part or even the entire equipment, which greatly increases the maintenance cost.

[0009] In the face of these technical problems, a new type of electronic endoscope design is urgently needed that can effectively reduce the risk of infection, simplify the reprocessing process, and improve the convenience of operation while ensuring the effectiveness of use, while taking into account the equipment's sealing, waterproof performance and long-term economic benefits. Summary of the invention

[0010] The purpose of the present application is to provide a detachable sterile protection structure for an electronic endoscope to solve the problems raised in the above-mentioned background technology.

[0011] The present application discloses a detachable sterile protection structure of an electronic endoscope, comprising an end seat assembly and a disposable detachable distal cover detachably connected to the end seat assembly through a connecting structure, wherein:

[0012] The end seat assembly is a reusable part, comprising: an end seat; a tong lifting block arranged in the end seat, the tong lifting block being able to rotate within a range of 0° to 90°; and a transmission mechanism arranged in the end seat and connected to the tong lifting block, for driving the tong lifting block to rotate;

[0013] The disposable detachable distal cover comprises: a distal end seat cap; a lifting clamp block arranged in the distal end seat cap; wherein,

[0014] When the disposable detachable distal cover is connected to the end seat assembly, the forceps lifting and shifting block and the forceps lifting block are docked with each other, so that the forceps lifting and shifting block can drive the forceps lifting block to rotate synchronously within the range of 0° to 90°.

[0015] In a preferred embodiment, when the forceps lifting block is rotated to the 0° position, the disposable detachable distal end cover can be removed from the end seat assembly, so as to facilitate replacement of the disposable detachable distal end cover with a new one.

[0017] A gear set disposed within the end housing; and

[0018] An operating mechanism disposed outside the end seat and connected to the gear set,

[0019] Wherein, the gear set is used to transmit and convert the rotational motion of the operating mechanism.

[0020] The operating mechanism is transmission-connected to the tong lifting and shifting block via the gear set, and is used to drive the tong lifting and shifting block to rotate within a range of 0° to 90°.

[0021] In a preferred embodiment, the connection structure includes:

[0022] At least one annular groove disposed on the periphery of the end seat; and

[0023] At least one annular block disposed on the inner side of the disposable detachable distal end cover and corresponding to the annular groove;

[0024] The annular clamping block is designed to be elastically deformable and snap into the annular clamping groove, so as to realize a quick, reliable and detachable connection between the disposable detachable distal cover and the end seat assembly;

[0025] The joint surface of the annular groove and the annular block is designed to form a sealed contact in the connected state to prevent external contaminants from entering;

[0026] When the lifting forceps shift block is rotated to the 0° position, the annular clamp block can be disengaged from the annular clamp groove, so as to facilitate the removal and replacement of the disposable detachable distal end cover.

[0027] In a preferred embodiment, it also includes:

[0028] At least one elastic sealing ring, which is an annular structure and is arranged in the annular groove of the end seat or on the annular block of the disposable detachable distal cover;

[0029] Wherein, the elastic sealing ring is made of a material with good elasticity and sealing performance, such as silicone rubber or fluororubber;

[0030] When the disposable detachable distal cover is connected to the end seat assembly, the elastic sealing ring is compressed between the annular groove and the annular block to form a reliable sealing interface;

[0031] The design of the elastic sealing ring not only enhances the sealing effect in the connected state, but also improves the waterproof and dustproof performance of the entire structure, further preventing external pollutants from entering the interior of the endoscope.

[0032] In a preferred embodiment, it is characterized in that:

[0033] At least one protrusion structure is provided at the end of the lifting and shifting block;

[0034] The lifting clamp block is provided with at least one groove structure matching the shape and size of the protruding structure;

[0035] Wherein, when the disposable detachable distal cover is connected to the end seat assembly, the protrusion structure can be accurately inserted and slidably matched in the groove structure, so as to realize reliable docking between the lifting and pulling block and the lifting and pulling block;

[0036] This docking design ensures that the rotational movement of the forceps lifting and shifting block can be accurately transmitted to the forceps lifting block, thereby achieving precise control of the endoscopic surgical instrument;

[0037] The design of the protrusion structure and the groove structure also allows the forceps lifting and shifting block to be easily separated from the forceps lifting block when the disposable detachable distal end cover is removed, thereby facilitating replacement and cleaning.

[0038] In a preferred embodiment, the tip seat cap is made of a transparent material to facilitate observation of the working status of the endoscope.

[0039] In a preferred embodiment, the disposable detachable distal cover further comprises a waterproof sealing ring arranged on the distal seat cap to prevent liquid from entering the interior of the endoscope.

[0040] In a preferred example, the end seat assembly further includes a locking mechanism for locking the lifting and shifting block when the lifting and shifting block is rotated to a preset angle.

[0041] In a preferred embodiment, corresponding marks are provided on the end seat assembly and the disposable detachable distal cover to indicate the correct connection position.

[0042] In a preferred embodiment, the operating mechanism comprises:

[0043] A tie rod assembly, the tie rod assembly comprising:

[0044] a) a tie rod disposed in the end seat, the tie rod being movable in the longitudinal direction;

[0045] b) an elastic element connected to the pull rod, used to provide a return force for the pull rod;

[0046] c) an operating handle disposed outside the end seat and connected to the pull rod;

[0047] Wherein, the distal end of the pull rod is designed to be able to engage with a corresponding structure in the disposable detachable distal cover when the disposable detachable distal cover is connected to the end seat assembly, so as to control additional functions of the endoscope.

[0048] Compared with the prior art, the embodiments of the present application have at least the following differences and effects:

[0049] 1) Reduce infection risk: During the reuse process of traditional duodenoscopes, due to its structural design, it is difficult to reprocess. If it is not handled properly, it may cause cross infection. This application adopts a disposable detachable distal cover design, so that a new distal cover can be replaced after each use, avoiding the possible residual tissue or body fluid on the instrument from entering the body of others, thereby significantly reducing the risk of infection.

[0050] 2) Simplify the reprocessing process: Since the distal end seat and the forceps lifter of the traditional endoscope are connected by pins, and the end seat cap and the end seat are adhered together, the reprocessing is very complicated and time-consuming. The end seat assembly and the disposable detachable distal cover of the present application are connected by a snap-fit ​​structure, which is very convenient to install and disassemble, greatly simplifying the reprocessing process and improving the use efficiency.

[0051] 3) Improve operational convenience: This application realizes the operational control of the endoscope by docking the lifting forceps shifting block with the lifting forceps block. The lifting forceps shifting block can rotate within the range of 0° to 90°, driving the lifting forceps block to rotate synchronously, thereby controlling the angle of the medical device in the endoscope. This design not only improves the flexibility and accuracy of the operation, but also enhances the convenience of use.

[0052] 4) Maintaining sealing and waterproof performance: The present application is designed to ensure the sealing performance of the connection through structures such as sealing rings to prevent contaminants from entering the interior. At the same time, the tip seat cap is made of transparent material, which is convenient for observing the working status of the endoscope, and the waterproof sealing ring design prevents liquid from entering the interior of the endoscope, ensuring the normal use of the equipment.

[0053] 5) Equipment maintenance and cost control:

[0054] Due to the detachable design of the present invention, the end seat assembly can be reused, and the disposable distal cover can be easily replaced, which not only reduces the complexity and cost of equipment maintenance, but also improves the service life and economic benefits of the equipment.

[0055] The present application uses an innovative detachable design to ensure aseptic operation and reduce the risk of infection, while significantly simplifying the reprocessing process, improving the convenience of operation and the economy of equipment maintenance. These technical effects ensure the practicality and application value of the present application in the field of endoscopy.

[0056] The specification of the present application records a large number of technical features, which are distributed in various technical solutions. If all possible combinations of technical features of the present application (i.e., technical solutions) are to be listed, the specification will be too long. In order to avoid this problem, the various technical features disclosed in the above invention content, the various technical features disclosed in the various embodiments and examples below, and the various technical features disclosed in the accompanying drawings can be freely combined with each other to form various new technical solutions (these technical solutions are all deemed to have been recorded in this specification), unless the combination of such technical features is technically infeasible.

Technically, only one can be used, and it is impossible to use them at the same time. Feature E can be combined with feature C technically. Then, the solution of A+B+C+D should not be deemed to have been recorded because it is technically infeasible, and the solution of A+B+C+E should be deemed to have been recorded.

[0103] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0104] First embodiment

[0105] See also Figures 1 to 8 This embodiment proposes a detachable sterile protection structure for an electronic endoscope, including an end seat module 1, and a disposable detachable distal cover 2 detachably connected to the end seat module 1 through a connection structure that maintains a seal in a connected state.

[0106] Specifically, the end seat module 1 is a reusable part, including: an end seat 1-1, a lifting and shifting block 1-7 arranged in the end seat 1-1, and a transmission mechanism arranged in the end seat 1-1 and connected to the lifting and shifting block 1-7.

[0107] More specifically, the tongs lifting and shifting block 1-7 is arranged in the end seat 1-1, and the tongs lifting and shifting block 1-7 can rotate within the range of 0° to 90°.

[0108] In addition, a transmission mechanism disposed in the end seat 1 - 1 and connected to the tongs lifting and shifting block 1 - 7 is used to drive the tongs lifting and shifting block 1 - 7 to rotate.

[0109] On the other hand, the disposable detachable distal cover 2 includes: a distal seat cap 2-1, and a lifting forceps block 2-2 arranged in the distal seat cap 2-1.

[0110] Among them, when the disposable detachable distal cover 2 is connected to the end seat module 1, the lifting and shifting block 1-7 and the lifting and shifting block 2-2 are docked with each other, so that the lifting and shifting block 1-7 can drive the lifting and shifting block 2-2 to rotate synchronously within the range of 0° to 90°.

[0111] It should be noted that when the lifting forceps block 1-7 is rotated to the 0° position, the disposable detachable distal cover 2 can be removed from the end seat module 1, so as to facilitate replacement of the new disposable detachable distal cover 2.

[0112] Specifically, this embodiment provides a detachable sterile protection structure of an electronic endoscope. The structure mainly consists of two parts: an end seat module 1 and a disposable detachable distal cover 2. The two parts are detachably connected together through a connection structure that can maintain a seal in a connected state.

[0113] The end seat module 1 is a reusable part of the structure. It mainly includes the end seat 1-1, in which the forceps lifting block 1-7 and the transmission mechanism connected thereto are arranged. The design of the forceps lifting block 1-7 allows it to rotate within the range of 0° to 90°, and the transmission mechanism is responsible for driving the rotational movement of the forceps lifting block 1-7. This design provides precise control capabilities for endoscope operation.

[0114] The disposable detachable distal cover 2 is another important component of the structure. It includes a tip seat cap 2-1 and a lifting block 2-2 arranged inside it. When the disposable detachable distal cover 2 is connected to the end seat module 1, the lifting block 1-7 will dock with the lifting block 2-2. This docking design enables the lifting block 1-7 to drive the lifting block 2-2 to rotate synchronously within the range of 0° to 90°, thereby realizing precise operation control of the endoscope.

[0115] It is worth noting that when the lifting forceps block 1-7 is rotated to the 0° position, the disposable detachable distal cover 2 can be easily removed from the end seat module 1. This design feature greatly facilitates the replacement process of the new disposable detachable distal cover 2. Through this detachable design, not only the cleaning and maintenance process of the equipment is simplified, but also the risk of cross infection is significantly reduced, providing higher hygiene protection for each surgical operation.

[0116] This design scheme combining reusable parts and disposable parts not only ensures the economic efficiency of the equipment, but also ensures the sanitation and safety during use. It represents an important trend in the design of modern medical equipment, which not only focuses on functionality and operating accuracy, but also fully considers sanitation, safety and maintenance convenience.

[0117] Optionally, the transmission mechanism includes:

[0118] A gear set disposed in the end seat 1-1 includes a conversion gear 1-9; and

[0119] An operating mechanism disposed outside the end seat 1-1 and connected to the gear set,

[0120] Wherein, the gear set is used to transmit and convert the rotational motion of the operating mechanism.

[0121] The operating mechanism is transmission-connected to the tong lifting and shifting block 1-7 via the gear set, and is used to drive the tong lifting and shifting block 1-7 to rotate within a range of 0° to 90°.

[0122] Optionally, the operating mechanism includes: a pull rod assembly, and the pull rod assembly includes:

[0123] a) a pull rod 1-2 disposed in the end seat 1-1, the pull rod 1-2 being able to move in the longitudinal direction;

[0124] b) a return spring 1-3 connected to the pull rod 1-2, used to provide a return force for the pull rod 1-2;

[0125] c) an operating handle disposed outside the end seat 1-1 and connected to the pull rod 1-2;

[0126] Among them, the distal end of the pull rod 1-2 is designed to be able to engage with the corresponding structure inside the disposable detachable distal cover 2 when the disposable detachable distal cover 2 is connected to the end seat module 1, so as to control the additional functions of the endoscope.

[0127] Specifically, if Figure 3-Figure 5 As shown, the transmission mechanism includes: a gear set arranged in the end seat 1-1, including a conversion gear 1-9; and an operating mechanism arranged outside the end seat 1-1 and connected to the gear set. Specifically, the gear set is used to transmit and convert the rotational motion of the operating mechanism, and the operating mechanism is connected to the lifting and shifting block 1-7 through the gear set, and is used to drive the lifting and shifting block 1-7 to rotate within the range of 0° to 90°.

[0128] Optionally, the operating mechanism includes a pull rod assembly. The pull rod assembly includes a pull rod 1-2 disposed in the end seat 1-1, the pull rod 1-2 being movable in the longitudinal direction; a return spring 1-3 connected to the pull rod 1-2, for providing a return force for the pull rod 1-2; and an operating handle disposed outside the end seat 1-1 and connected to the pull rod 1-2.

[0129] Specifically, when the user drives the pull rod 1-2 to move longitudinally through the operating handle, the movement of the pull rod 1-2 is transmitted to the conversion gear 1-9. The conversion gear 1-9 converts the longitudinal movement of the pull rod 1-2 into rotational movement through the gear set, and transmits the rotational movement to the forceps lifting block 1-7. With this design, the forceps lifting block 1-7 can be accurately rotated within the range of 0° to 90°, thereby achieving precise control of the angle of the medical device during the endoscope operation.

[0130] When the disposable detachable distal cover 2 is connected to the end seat module 1, the distal end of the pull rod 1-2 can engage with the corresponding structure in the disposable detachable distal cover 2. At this time, every movement of the operating handle can be transmitted to the gear set through the pull rod assembly, and finally drive the rotation of the forceps lifting and shifting block 1-7. This design not only ensures the efficiency and reliability of the transmission mechanism, but also greatly simplifies the complexity of endoscope operation and improves the convenience of use of the device.

[0131] More specifically, optional, such as Figures 3 to 5As shown, the part where the pull rod 1-2 is connected to the conversion gear 1-9 has a special shape design. Specifically, this end of the pull rod 1-2 presents a unique structure: its cross section is trapezoidal, and the longitudinal direction is designed as an inclined rack structure. This composite design precisely meshes with the conversion gear 1-9 to form an efficient rack-pinion mechanism.

[0132] The trapezoidal cross section of the pull rod 1-2 is formed by precision machining to ensure that it can maintain stable meshing with the conversion gear 1-9 when moving longitudinally. At the same time, the inclined rack structure on its surface is the key to achieving motion conversion. When the pull rod 1-2 moves longitudinally, this inclined rack part can effectively drive the conversion gear 1-9 to rotate, thereby accurately converting the linear motion of the pull rod into the rotational motion of the gear.

[0133] The advantages of doing so are: 1) Efficient motion conversion: The inclined rack structure can efficiently convert the linear motion of the pull rod 1-2 into the rotational motion of the conversion gear 1-9, minimizing energy loss. 2) Precise control: By adjusting the inclination angle of the rack, the pitch of the tooth and the size of the gear, the conversion ratio of linear motion to rotational motion can be accurately controlled to achieve precise adjustment of the angle of the endoscopic surgical instrument. 3) Connection stability: The trapezoidal cross-section design enhances the meshing stability of the pull rod and the gear, ensuring that no slippage or disengagement occurs during the transmission process, providing a reliable transmission connection. 4) Smooth transmission: The optimized rack-pinion structure ensures the smoothness of the motion transmission process and effectively reduces vibration and noise during the transmission process. 5) Compact design: This structure allows complex motion conversion to be achieved in a limited space, making the entire transmission mechanism more compact and suitable for the limited space requirements of the endoscope. 6) Durable and reliable: Compared with other motion conversion mechanisms, this rack-pinion structure has higher durability and reliability and can withstand wear and tear from long-term use.

[0134] Through this innovative rack-and-pinion design, the longitudinal movement of the pull rod 1-2 can be efficiently and accurately converted into the rotational movement of the conversion gear 1-9, and then transmitted to the forceps lifting block 1-7 through the gear set, so as to achieve precise angle control of the endoscopic surgical instrument. This design not only improves the transmission efficiency and operation accuracy, but also simplifies the operation process, greatly improving the convenience of use and overall performance of the endoscope.

[0135] Through the above design, this embodiment realizes the precise control of the lifting and shifting blocks 1-7, so that the lifting and shifting blocks 2-2 can rotate synchronously, thereby improving the flexibility and accuracy of endoscopic surgery. At the same time, the introduction of the pull rod assembly not only ensures the reliability and stability of motion transmission, but also simplifies the operation process and improves the convenience and efficiency of use. This technical solution not only solves many problems encountered by traditional endoscopes during operation, but also significantly improves the performance and user experience of the equipment.

[0136] Optionally, at least one protruding structure is provided at the end of the lifting and shifting block 1-7;

[0137] The lifting clamp block 2-2 is provided with at least one groove structure matching the shape and size of the protruding structure;

[0138] When the disposable detachable distal cover 2 is connected to the end seat module 1, the protrusion structure can be accurately inserted and slidably matched in the groove structure, so as to realize reliable docking between the lifting and pulling block 1-7 and the lifting and pulling block 2-2;

[0139] This docking design ensures that the rotational movement of the forceps lifting and shifting block 1-7 can be accurately transmitted to the forceps lifting block 2-2, thereby achieving precise control of the endoscopic surgical instrument;

[0140] The design of the protrusion structure and the groove structure also allows the forceps lifting block 1-7 to be easily separated from the forceps lifting block 2-2 when the disposable detachable distal cover 2 is removed, so as to facilitate replacement and cleaning.

[0141] Specifically, if Figure 3 , Figure 7 and Figure 8 As shown, at least one rectangular protrusion structure is provided at the end of the lifting forceps block 1-7, and its short side is tangent to the circumferential contour of the lifting forceps block. The rectangular protrusion structure is formed by cutting a plane perpendicular to the axis, so that it has a flat surface for precise transmission and positioning; the lifting forceps block 2-2 is provided with at least one groove structure matching the shape and size of the protrusion structure. Wherein, when the disposable detachable distal cover 2 is connected to the end seat mold assembly 1, the protrusion structure can be accurately inserted and slidably fitted into the groove structure, so as to realize the reliable docking of the lifting forceps block 1-7 and the lifting forceps block 2-2. The docking design ensures that the rotational movement of the lifting forceps block 1-7 can be accurately transmitted to the lifting forceps block 2-2, thereby realizing precise control of the endoscopic surgical instrument; the design of the protrusion structure and the groove structure also allows the lifting forceps block 1-7 to be easily separated from the lifting forceps block 2-2 when the disposable detachable distal cover 2 is removed, which is convenient for replacement and cleaning.

[0142] In other words, at least one protrusion structure is provided at the end of the lifting and shifting block 1-7. The design of the protrusion structure enables it to provide stable connection and transmission when docking with the lifting and shifting block 2-2. The lifting and shifting block 2-2 is provided with at least one groove structure that matches the shape and size of the protrusion structure. The design of the groove structure ensures that when the protrusion structure is inserted, a precise sliding fit can be formed, thereby ensuring the reliability of docking. When the disposable detachable distal cover 2 is connected to the end seat module 1, the protrusion structure of the lifting and shifting block 1-7 can be accurately inserted and slidably fitted into the groove structure of the lifting and shifting block 2-2. This docking design enables the lifting and shifting block 1-7 to drive the lifting and shifting block 2-2 to rotate synchronously, thereby achieving precise control of the endoscopic surgical instrument. Through the above-mentioned docking design, the rotational movement of the lifting and shifting block 1-7 can be accurately transmitted to the lifting and shifting block 2-2. This transmission not only ensures the operating accuracy of the endoscopic surgical instrument, but also improves the flexibility and reliability of the operation. The design of the protrusion structure and the groove structure also allows the lifting block 1-7 to be easily separated from the lifting block 2-2 when the disposable detachable distal cover 2 is removed. This design greatly simplifies the replacement and cleaning process, and improves the maintenance convenience and operating efficiency of the equipment. Through the above design, this embodiment improves the operating accuracy and flexibility of the endoscopic surgical instrument while ensuring the docking reliability. At the same time, this docking design also facilitates the removal and replacement of the disposable detachable distal cover 2, simplifies the cleaning and maintenance process of the equipment, and reduces the risk of cross infection.

[0143] Optionally, the connection structure includes:

[0144] At least one annular groove disposed on the periphery of the end seat 1-1; and

[0145] At least one annular block disposed on the inner side of the disposable detachable distal end cover 2 and corresponding to the annular groove;

[0146] The annular clamping block is designed to be elastically deformable and snap into the annular clamping groove, so as to realize a quick, reliable and detachable connection between the disposable detachable distal cover 2 and the end seat module 1;

[0147] The joint surface of the annular groove and the annular block is designed to form a sealed contact in the connected state to prevent external contaminants from entering;

[0148] When the lifting forceps shift block 1-7 is rotated to the 0° position, the annular clamp block can be disengaged from the annular clamp groove, so as to facilitate the removal and replacement of the disposable detachable distal cover 2.

[0149] Specifically, see Figure 1 and Figure 2, the connection structure includes: at least one annular groove arranged on the periphery of the end seat 1-1; and at least one annular block arranged on the inner side of the disposable removable distal cover 2 and corresponding to the annular groove. Specifically, the annular block is designed to be elastically deformed and snapped into the annular groove, so as to achieve a quick, reliable and detachable connection between the disposable removable distal cover 2 and the end seat module 1. The mating surfaces of the annular groove and the annular block are designed to form a sealed contact in the connected state to prevent external contaminants from entering. When the lifting forceps block 1-7 is rotated to the 0° position, the annular block can be detached from the annular groove, which is convenient for disassembly and replacement of the disposable removable distal cover 2.

[0150] In other words, the annular groove is arranged on the periphery of the end seat 1-1. The annular groove is used to accommodate and fix the annular block of the disposable detachable distal cover 2. The design of the annular groove ensures the stability and sealing of the connection. The annular block is arranged on the inner side of the disposable detachable distal cover 2 and corresponds to the annular groove. The annular block is designed to be elastically deformable so that it can produce a certain elastic deformation when inserted into the annular groove, thereby achieving a tight fit. This elastic deformation characteristic of the annular block ensures the stability and reliability of the connection. When the disposable detachable distal cover 2 is connected to the end seat module 1, the annular block can be quickly and reliably inserted into the annular groove to achieve a tight connection. This design not only ensures the firmness of the connection, but also greatly improves the convenience of installation and disassembly. The joint surface of the annular groove and the annular block is designed to form a sealed contact in the connected state. This sealing design can effectively prevent external contaminants from entering the interior, thereby ensuring the sterile operating environment of the endoscope and improving the safety and service life of the equipment. When the lifting forceps block 1-7 is rotated to the 0° position, the annular clamp block can be disengaged from the annular clamp groove. This design allows the disposable detachable distal cover 2 to be easily disassembled, making it easy to replace the new distal cover. This not only simplifies the cleaning and maintenance process of the equipment, but also significantly reduces the risk of cross infection. Through the above design, this embodiment provides an efficient and reliable connection structure. The design of the annular clamp groove and the annular clamp block ensures a quick and reliable connection, and forms a sealed contact in the connected state to prevent external contaminants from entering. At the same time, when the lifting forceps block 1-7 is rotated to the 0° position, the disposable detachable distal cover 2 can be easily disassembled and replaced, which improves the maintenance convenience and operating efficiency of the equipment. While ensuring the functionality of the equipment, this design also greatly improves the convenience and safety of use.

[0151] Optionally, the detachable sterile protection structure of the electronic endoscope of this embodiment further includes:

[0152] At least one elastic sealing ring, which is an annular structure and is arranged in the annular groove of the end seat 1-1 or on the annular block of the disposable detachable distal cover 2;

[0153] Wherein, the elastic sealing ring is made of a material with good elasticity and sealing performance, such as silicone rubber or fluororubber;

[0154] When the disposable detachable distal cover 2 is connected to the end seat module 1, the elastic sealing ring is compressed between the annular groove and the annular block to form a reliable sealing interface;

[0155] The design of the elastic sealing ring not only enhances the sealing effect in the connected state, but also improves the waterproof and dustproof performance of the entire structure, further preventing external pollutants from entering the interior of the endoscope.

[0156] Specifically, the detachable sterile protection structure of the electronic endoscope of this embodiment also includes: at least one elastic sealing ring, which is an annular structure and is arranged in the annular groove of the end seat 1-1 or on the annular block of the disposable detachable distal cover 2. Wherein, the elastic sealing ring is made of a material with good elasticity and sealing performance, such as silicone rubber or fluororubber. When the disposable detachable distal cover 2 is connected to the end seat module 1, the elastic sealing ring is compressed between the annular groove and the annular block to form a reliable sealing interface. The design of the elastic sealing ring not only enhances the sealing effect in the connected state, but also improves the waterproof and dustproof performance of the entire structure, further preventing external contaminants from entering the interior of the endoscope.

[0157] In other words, the elastic sealing ring is an annular structure, which is specially designed to form a sealing interface in the annular groove of the end seat 1-1 or on the annular block of the disposable removable distal cover 2. The setting position of the elastic sealing ring ensures that the entry of external contaminants can be effectively prevented in the connected state. The elastic sealing ring is made of a material with good elasticity and sealing performance, such as silicone rubber or fluororubber. These materials not only have excellent elasticity and durability, but also can maintain good sealing performance in a compressed state, thereby ensuring the sterile environment of the endoscope. When the disposable removable distal cover 2 is connected to the end seat module 1, the elastic sealing ring is compressed between the annular groove and the annular block. The elastic sealing ring in a compressed state can form a reliable sealing interface to ensure the sealing effect of the connection. Whether in use or in the cleaning and maintenance process, the elastic sealing ring can effectively prevent the infiltration of liquids and particulate matter. The design of the elastic sealing ring not only enhances the sealing effect in the connected state, but also significantly improves the waterproof and dustproof performance of the entire structure. Through the action of the elastic sealing ring, external contaminants can be further prevented from entering the interior of the endoscope, thereby improving the safety and service life of the equipment. Due to the excellent sealing performance of the elastic sealing ring, the detachable sterile protection structure of the electronic endoscope of this embodiment can maintain high waterproof and dustproof performance in various environments. Whether in a humid operating environment or in a dusty operating environment, the internal structure of the endoscope can be effectively protected.

[0158] Through the above design, the detachable sterile protection structure of the electronic endoscope of this embodiment not only ensures efficient sealing, but also significantly improves the waterproof and dustproof performance of the equipment. The introduction of the elastic sealing ring not only enhances the reliability of the connection, but also effectively prevents the entry of external contaminants, thereby ensuring the safety and hygiene of the endoscope during use. This design not only ensures the functionality of the equipment, but also greatly improves the convenience of use and maintenance.

[0159] Optionally, the end seat module 1 further includes a locking mechanism for locking the lifting and shifting block 1-7 when it is rotated to a preset angle.

[0160] Specifically, see Figure 1 and Figure 6 The end seat module 1 also includes a locking mechanism for locking the lifting and shifting block 1-7 when it rotates to a preset angle. The design of the locking mechanism ensures that the lifting and shifting block 1-7 can maintain a stable angle during operation, thereby improving the accuracy and safety of endoscope operation.

[0161] More specifically, optionally, the end seat module 1 includes a specially designed locking mechanism, which is used to lock the lifting tongs block 1-7 when it is rotated to a preset angle. The main function of the locking mechanism is to ensure that the lifting tongs block 1-7 does not move accidentally at a specific operating angle, thereby improving the stability and safety of the operation. Optionally, the specific structure of the locking mechanism may include a spring-loaded locking pin or a gear brake. The locking pin can pop out and snap into the corresponding locking hole when the lifting tongs block 1-7 is rotated to a preset angle, thereby fixing the lifting tongs block 1-7 at this angle. The gear brake can lock the lifting tongs block 1-7 at a preset angle by gear engagement. When the lifting tongs block 1-7 is rotated to a preset angle, the locking mechanism is automatically activated to ensure the stability of the lifting tongs block 1-7. For example, when the lifting tongs block 1-7 is rotated to 90°, the locking mechanism will lock it to prevent angle deviation caused by external forces during operation. This design not only improves the accuracy of the operation, but also enhances the safety performance of the equipment. When it is necessary to adjust the angle of the lifting block 1-7, the user can release the locking mechanism through specific operations, such as pressing a specific unlocking button or rotating the control knob to disengage the locking pin or the gear brake device from the locked state. This design facilitates the operator to quickly adjust the angle of the lifting block 1-7 during different surgical procedures. Through the above design, this embodiment provides an efficient and reliable locking mechanism to ensure the stability and safety of the lifting block 1-7 at a preset angle. The locking mechanism not only enhances the operating accuracy of the equipment, but also improves the convenience and safety of use. During endoscopic surgery, the introduction of the locking mechanism can effectively prevent surgical risks caused by angle deviation, and further ensure the smooth progress of the operation.

[0162] Optionally, corresponding marks are provided on the end seat module 1 and the disposable detachable distal cover 2 to indicate the correct connection position.

[0163] Specifically, corresponding marks are provided on the end seat module 1 and the disposable detachable distal cover 2 to indicate the correct connection position. The design of these marks enables the user to quickly and accurately connect the disposable detachable distal cover 2 to the end seat module 1, ensuring the stability and safety of the device during use.

[0164] More specifically, the end seat module 1 and the disposable removable distal cover 2 are respectively provided with corresponding marks. These marks can be color marks, shape marks or text marks to help users quickly align the correct position when connecting. For example, red and blue marks can be set on the end seat 1-1 and the tip seat cap 2-1 respectively, and when the two are aligned, it is the correct connection position. The mark on the end seat 1-1 is usually set in a conspicuous position, which is convenient for users to observe and align during the installation process. Similarly, the mark on the tip seat cap 2-1 is also set in an obvious position, so that the two can be easily aligned, thereby achieving quick connection. These marks are used to indicate the correct connection position to ensure that all parts of the disposable removable distal cover 2 can be correctly docked and fixed when it is connected to the end seat module 1. The correct connection position can ensure the reliable docking of the lifting forceps block 1-7 and the lifting forceps block 2-2, and ensure the accuracy of transmission and operation. By setting these marks, when installing and removing the disposable removable distal cover 2, the user does not need to perform cumbersome alignment operations, and only needs to align the marks to complete the installation. This not only improves the convenience of use, but also reduces the possibility of incorrect installation, thereby improving the efficiency and safety of the equipment. The design of these marks should be clear and easy to understand, and can be clearly seen under different lighting conditions. Common designs include marks with strong color contrast, raised or recessed shape marks, and arrow marks with direction indication. This design ensures that users can complete the connection quickly and accurately even in a tense surgical environment.

[0165] Through the above design, this embodiment provides a convenient and fast marking system for indicating the correct connection position of the disposable detachable distal cover 2 and the end seat module 1. These marks not only improve the accuracy and convenience of the connection, but also enhance the safety of the device and prevent device failure or surgical risks caused by incorrect installation. This design not only ensures the functionality of the device, but also greatly improves the user's operating experience.

[0166] Optionally, the disposable detachable distal cover 2 also includes a waterproof sealing ring arranged on the distal seat cap 2-1 to prevent liquid from entering the interior of the endoscope.

[0167] Specifically, the disposable detachable distal cover 2 optionally further includes a waterproof seal ring disposed on the distal end cap 2-1 to prevent liquid from entering the interior of the endoscope. The design of the waterproof seal ring ensures that liquid does not penetrate into the interior of the device during the use of the endoscope, thereby improving the waterproof performance and service life of the device.

[0168] More specifically, optionally, the disposable removable distal cover 2 includes a waterproof seal ring, which is arranged on the tip seat cap 2-1. The main function of the waterproof seal ring is to prevent liquid from entering the interior of the endoscope and protect the internal components of the device from being damaged by liquid. The waterproof seal ring is usually made of a durable material with high sealing performance, such as silicone rubber or fluororubber. The waterproof seal ring is installed on the edge or inside of the tip seat cap 2-1, and when connected to the end seat 1-1, the seal ring can form a close contact. This design not only ensures the waterproof effect, but also enhances the overall sealing performance in the connected state to prevent liquid from entering the interior of the device. When the disposable removable distal cover 2 is connected to the end seat module 1, the waterproof seal ring is compressed between the two to form an effective waterproof barrier. The seal ring in this compressed state can block the liquid that may be generated during the operation and prevent it from entering the internal circuit and optical components of the endoscope. The provision of the waterproof seal ring not only improves the waterproof performance of the device, but also enhances the overall protection effect. By preventing liquid from entering the interior of the endoscope, equipment failures and damage caused by liquid intrusion are reduced, and the service life of the equipment is extended. The waterproof sealing ring is made of high-quality sealing materials, such as silicone rubber or fluororubber. These materials not only have excellent elasticity and durability, but also can maintain good sealing performance in high pressure and complex use environments. The choice of materials ensures that the waterproof sealing ring can maintain a stable waterproof effect during long-term use. Through the above design, this embodiment provides an efficient waterproof sealing structure, which ensures that the endoscope can effectively prevent liquid from entering the inside of the device during use. The provision of a waterproof sealing ring not only improves the protective performance of the equipment, but also enhances the durability and service life of the equipment. This design not only ensures the functionality of the equipment, but also greatly improves the user's operating safety and the reliability of the equipment.

[0169] Optionally, the tip seat cap 2-1 is made of a transparent material to facilitate observation of the working status of the endoscope.

[0170] Specifically, the tip seat cap 2-1 is optionally made of a transparent material to facilitate observation of the working state of the endoscope. The purpose of this design is to enable the operator to observe the working state of the endoscope in real time by using a transparent material, thereby ensuring the normal operation of the device during the operation and improving the safety and accuracy of the operation.

[0171] More specifically, the tip seat cap 2-1 is made of transparent materials, which may include transparent plastics or transparent glass. The selection of transparent materials not only ensures the strength and durability of the cap, but also provides good optical transmittance, so that the operator can clearly observe the working status of the endoscope. Due to the transparent characteristics of the tip seat cap 2-1, the operator can directly observe the situation inside the endoscope through the cap, such as the status of the internal optical components and electronic components. This design allows the operator to check whether the endoscope is working properly at any time during the operation, and to find and solve possible problems in time. Through the transparent tip seat cap 2-1, the operator can better monitor the working status of the endoscope and ensure that the equipment runs smoothly during the operation. This real-time monitoring capability greatly improves the safety of the operation and reduces the surgical risks caused by equipment failure. The selection of transparent materials should have high transparency and excellent mechanical properties, such as impact resistance, wear resistance and chemical corrosion resistance. Commonly used transparent materials include polycarbonate (PC), acrylic acid (PMMA) and optical glass. These materials not only provide excellent optical properties, but also ensure the durability and reliability of the tip seat cap 2-1. The optical properties of transparent materials are crucial to the normal use of the endoscope. High-quality transparent materials should have high light transmittance and low refractive index to ensure the clarity and accuracy of image transmission. In addition, the material should also have good anti-reflection properties to reduce the reflection of light on the surface of the material, thereby improving the observation effect. Through the above design, the tip seat cap 2-1 of this embodiment is made of transparent material, so that the operator can observe the working status of the endoscope in real time. This design not only improves the monitoring capability and operational safety of the equipment, but also enhances the accuracy and reliability of the operation. The selection and application of transparent materials ensure that the endoscope can operate stably during the operation, providing a strong guarantee for the success of the operation.

[0172] Working principle:

[0173] The working principle of the above embodiment is described below. During use, the end seat assembly 1 drives the lifting block 1-7 to rotate through the transmission mechanism inside it. When the pull rod 1-2 of the operating mechanism moves longitudinally under the drive of the operating handle, the movement of the pull rod 1-2 is transmitted through the conversion gear 1-9, and the linear movement of the pull rod 1-2 is converted into the rotational movement of the lifting block 1-7. The rotation range of the lifting block 1-7 is 0° to 90°, thereby driving the lifting block 2-2 in the disposable detachable distal cover 2 to rotate synchronously.

[0174] When installing the disposable detachable distal cover 2, first rotate the lifting block 1-7 to the 0° position, and then align the disposable detachable distal cover 2 with the corresponding mark of the end seat assembly 1 to ensure the correct connection position. At this time, the protruding structure of the lifting block 1-7 is accurately inserted into the groove structure of the lifting block 2-2 to form a reliable connection. As the lifting block 1-7 rotates, the lifting block 2-2 also rotates synchronously to achieve angle control of the medical device inside the endoscope.

[0175] After use, the lifting forceps block 1-7 is rotated to the 0° position again, and the user can easily remove the disposable detachable distal cover 2. Through this design, the end seat assembly 1 can be easily reprocessed, and when reused, only a new disposable detachable distal cover 2 needs to be replaced, achieving a disposable effect and avoiding the risk of cross infection.

[0176] During the whole process, the waterproof sealing ring of the end seat assembly 1 and the disposable detachable distal cover 2 and the transparent distal seat cap 2-1 ensure the sealing and visibility of the device, so that the operator can monitor the working status of the endoscope in real time to ensure the safety and smoothness of the surgical process. At the same time, the locking mechanism ensures the stability of the lifting forceps block 1-7 during the operation, prevents angle deviation, and improves the accuracy of the operation.

[0177] Through the above structure and working principle, the detachable sterile protection structure of the electronic endoscope of the present invention not only improves the operating convenience and safety of the endoscope, but also significantly reduces the complexity and cost of equipment maintenance, and improves the use efficiency.

[0178] The advantages of the above implementation are as follows:

[0179] 1) Reduce infection risk: During the reuse process of traditional duodenoscopes, due to their structural design, reprocessing is difficult, and if improperly handled, cross infection may occur. The above embodiment uses a disposable detachable distal cover design so that a new distal cover can be replaced after each use, thereby preventing tissue or body fluid that may remain on the instrument from entering the body of another person, thereby significantly reducing the risk of infection.

[0180] 2) Simplified reprocessing process: Since the distal end seat and the forceps lifter of the traditional endoscope are connected by pins, and the end seat cap and the end seat are adhered together, reprocessing is very complicated and time-consuming. The end seat assembly and the disposable detachable distal cover of the above embodiment are connected by a snap-fit ​​structure, which is very convenient to install and disassemble, greatly simplifying the reprocessing process and improving the use efficiency.

[0181] 3) Improve operational convenience: The above embodiment realizes the operation control of the endoscope by docking the lifting forceps shifting block with the lifting forceps block. The lifting forceps shifting block can rotate within the range of 0° to 90°, driving the lifting forceps block to rotate synchronously, thereby controlling the angle of the medical device in the endoscope. This design not only improves the flexibility and accuracy of the operation, but also enhances the convenience of use.

[0182] 4) Maintaining sealing and waterproof performance: The above embodiment is designed to ensure the sealing performance of the connection through structures such as sealing rings to prevent contaminants from entering the interior. At the same time, the tip seat cap is made of transparent material, which is convenient for observing the working status of the endoscope, and the waterproof sealing ring design prevents liquid from entering the interior of the endoscope, ensuring the normal use of the equipment.

[0183] 5) Equipment maintenance and cost control:

[0184] Due to the detachable design of the above embodiment, the end seat assembly can be reused, and the disposable distal end cover can be easily replaced, which not only reduces the complexity and cost of equipment maintenance, but also increases the service life and economic benefits of the equipment.

[0185] The above embodiment, through the innovative detachable design, significantly simplifies the reprocessing process while ensuring aseptic operation and reducing the risk of infection, and improves the convenience of operation and the economy of equipment maintenance. These technical effects ensure the practicality and application value of the above embodiment in the field of endoscopy.

[0186] In order to better understand the technical solution of the present application, a specific example is provided below for illustration. The details listed in the example are mainly for ease of understanding and are not intended to limit the scope of protection of the present application.

[0187] like Figure 1 , Figure 2As shown, the detachable sterile protection structure of the electronic endoscope in this example includes: an end seat assembly 1, a disposable detachable distal cover 2. The end seat module 1-7 lifting and shifting block can rotate within the range of 0°-90° under the drive of the 1-2 pull rod, and the disposable detachable distal cover 2-2 lifting and shifting block can rotate within the range of 0°-90° under the drive of the 1-7 lifting and shifting block. When the end seat assembly 1-7 lifting and shifting block is rotated to the 0° position, the disposable detachable distal cover 2-2 lifting and shifting block is also rotated to the 0° position, and the 2 disposable detachable distal cover can be inserted into the end seat assembly 1. At this time, the end seat assembly 1-7 lifting and shifting block can drive the disposable detachable distal cover 2-2 lifting and shifting block to rotate synchronously within the range of 0°-90°. After use, when the end seat assembly 1-7 lifting forceps block is turned to the 0° position, the disposable detachable distal cover 2 can be removed. After removal, the end seat assembly 1 is convenient for reprocessing, and when reused, only the new 2 disposable detachable distal covers need to be replaced to achieve the disposable use effect.

[0188] like Figure 3 , Figure 4 , Figure 5 As shown, the detachable sterile protection structure of the endoscope is subdivided into: end seat 1-1, pull rod 1-2, return spring 1-3, limit rod 1-4, positioning tube 1-5, lifting clamp block sealing ring 1-6, lifting clamp block 1-7, lifting clamp block positioning wheel bearing 1-8, conversion gear 1-9, gear baffle 1-10, sealing sheet 1-11, sealing plug 1-12, front end seat cap 2-1, lifting clamp block 2-2. The end seat 1-1 is the main load-bearing part in the assembly, and other parts are mainly matched with it. First, the lifting and pulling block sealing ring 1-6, the lifting and pulling block 1-7, and the lifting and pulling block positioning wheel bearing 1-8 are tightly fitted and sequentially installed into the side hole of the end seat 1-1, and then the pull rod 1-2, the return spring 1-3, the limit rod 1-4, the positioning tube 1-5 are sequentially installed, and then the conversion gear 1-9 (matched with the pull rod 1-2), the gear baffle 1-10, the sealing plate 1-11 (sealed and fixedly connected with the end seat 1-1), and the sealing plug 1-12 are sequentially installed, and the end seat assembly 1 is now complete. The lifting and pulling block 2-2 is installed in the rotating hole of the front seat cap 2-1 to complete the disposable detachable distal cover 2.

[0189] like Figure 4 , Figure 5 As shown, the pull rod 1-2, the return spring 1-3, the limit rod 1-4, the positioning tube 1-5 (sealed and fixed to the end seat 1-1), and the sealing plug 1-12 (sealed and fixed to the end seat 1-1) are sequentially installed into the hole of the end seat 1-1, and the conversion gear 1-9 is connected and matched with the pull rod 1-2 gear.

[0190] like Figure 4 , Figure 5As shown, the lifting and shifting block sealing ring 1-6 is installed in the side hole of the end seat 1-1 (sealed with the side hole of the end seat 1-1), the lifting and shifting block 1-7 is installed in the hole of the lifting and shifting block sealing ring 1-6 (with the functions of rotation and sealing), the lifting and shifting block positioning wheel bearing 1-8 is inserted into the lifting and shifting block 1-7 and tightly fixed with the side hole of the end seat 1-1, the conversion gear 1-9 is inserted into the square hole of the lifting and shifting block 1-7 and embedded (the conversion gear 1-9 drives the lifting and shifting block 1-7 to rotate together), the gear baffle 1-10 (prevents the conversion gear 1-9 from moving), and the sealing plate 1-11 (brazed and sealed with the end seat 1-1).

[0191] Here's how this example works:

[0192] During use, the end seat assembly 1 drives the lifting block 1-7 to rotate through the transmission mechanism inside it. When the pull rod 1-2 moves longitudinally under the drive of the operating handle, the conversion gear 1-9 converts the linear motion of the pull rod 1-2 into the rotational motion of the lifting block 1-7. The rotation range of the lifting block 1-7 is 0° to 90°, thereby driving the lifting block 2-2 in the disposable detachable distal cover 2 to rotate synchronously.

[0193] When installing the disposable detachable distal cover 2, first rotate the lifting block 1-7 to the 0° position, and then align the disposable detachable distal cover 2 with the corresponding mark of the end seat assembly 1 to ensure the correct connection position. At this time, the protruding structure of the lifting block 1-7 is accurately inserted into the groove structure of the lifting block 2-2 to form a reliable connection. As the lifting block 1-7 rotates, the lifting block 2-2 also rotates synchronously to achieve angle control of the medical device inside the endoscope.

[0194] After use, the lifting forceps block 1-7 is rotated to the 0° position again, and the user can easily remove the disposable detachable distal cover 2. Through this design, the end seat assembly 1 can be easily reprocessed, and when reused, only a new disposable detachable distal cover 2 needs to be replaced, achieving a disposable effect and avoiding the risk of cross infection.

[0195] During the whole process, the waterproof sealing ring of the end seat assembly 1 and the disposable detachable distal cover 2 and the transparent distal seat cap 2-1 ensure the sealing and visibility of the device, so that the operator can monitor the working status of the endoscope in real time to ensure the safety and smoothness of the surgical process. At the same time, the locking mechanism ensures the stability of the lifting forceps block 1-7 during the operation, prevents angle deviation, and improves the accuracy of the operation.

[0196] Through the above structure and working principle, the detachable sterile protection structure of the electronic endoscope of the present invention not only improves the operating convenience and safety of the endoscope, but also significantly reduces the complexity and cost of equipment maintenance, and improves the use efficiency.
