Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to endoscope technology. Background Art

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

[0003] Currently, in the distal seat structure of the insertion part of most reusable duodenoscopes, the elevator and the end seat are usually connected together with pins, and the end seat cap and the end seat are adhesively integrated. Although this design has a certain stability during use, it also brings a series of problems:

[0004] Infection risk: This fixed structure makes the reprocessing of duodenoscopes very difficult. If the reprocessing is not done properly, it may cause the patient's tissue or body fluid to remain on the instrument and then enter the body of other patients during the next use, resulting in cross-infection.

[0005] Complex reprocessing: Due to the fixed structure, the cleaning and disinfection processes become complex and time-consuming. Especially for some small gaps and connections, it is difficult to ensure thorough cleaning, which not only increases the workload of medical institutions but also may affect the use efficiency of the equipment.

[0006] Operation limitation: In the traditional design, the operation of the elevator is often restricted by the structure and it is difficult to achieve precise and flexible control, which may affect the effect of some complex operations performed by doctors.

[0007] Sealing problem: The fixed structure may experience a decline in sealing performance after long-term use, increasing the risk of contaminants entering the interior or liquid seeping in, affecting the normal use and lifespan of the equipment.

[0008] High maintenance cost: Due to the difficulty of disassembly, when a part of the equipment fails, it is often necessary to replace the entire component or even the entire equipment, which greatly increases the maintenance cost.

[0009] Facing these technical problems, there is an urgent need for a new type of electronic endoscope design that can effectively reduce the infection risk, simplify the reprocessing process, improve the operation convenience, while taking into account the sealing performance, waterproof performance of the equipment and the economic benefits of long-term use while ensuring the use effect. Utility Model Content

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

[0011] The present application discloses a detachable sterile protection structure for an electronic endoscope, including an end seat assembly and a disposable detachable distal cap detachably connected to the end seat assembly through a connection structure. Among them,

[0012] The end seat assembly is a reusable part, including: an end seat; a forceps lifting block disposed in the end seat, the forceps lifting block being capable of rotating within a range of 0° to 90°; and a transmission mechanism disposed in the end seat and connected to the forceps lifting block for driving the forceps lifting block to rotate;

[0013] The disposable detachable distal cap includes: a distal end seat cap; a forceps lifting block disposed in the distal end seat cap; among them,

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

[0015] In a preferred example, when the forceps lifting block rotates to the 0° position, the disposable detachable distal cap can be detached from the end seat assembly, facilitating the replacement of a new disposable detachable distal cap.

[0016] In a preferred example, the transmission mechanism includes:

[0017] A gear set disposed in the end seat; and

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

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

[0020] The operating mechanism is in transmission connection with the forceps lifting block through the gear set for driving the forceps lifting block to rotate within a range of 0° to 90°.

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

[0022] At least one annular slot 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 cap corresponding to the annular slot;

[0024] Among them, the annular block is designed to be elastically deformable and snap into the annular slot to achieve a quick, reliable and detachable connection between the disposable detachable distal cap and the end seat assembly;

[0025] The mating surfaces of the annular slot and the annular block are designed to form a sealed contact in the connected state to prevent external contaminants from entering;

[0026] When the lifting force pliers block rotates to the 0° position, the annular block can be disengaged from the annular slot, facilitating the disassembly and replacement of the disposable detachable distal cap.

[0027] In a preferred example, it further includes:

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

[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 cap is connected to the end seat assembly, the elastic sealing ring is compressed between the annular slot 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 whole structure, further preventing external contaminants from entering the endoscope.

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

[0033] At least one convex structure is provided at the end of the lifting force pliers block;

[0034] At least one groove structure matching the shape and size of the convex structure is provided on the lifting force pliers block;

[0035] Wherein, when the disposable detachable distal cap is connected to the end seat assembly, the convex structure can be accurately inserted and slidably fitted into the groove structure to achieve reliable docking of the lifting force pliers block and the lifting force pliers block;

[0036] This docking design ensures that the rotational movement of the lifting force pliers block can be accurately transmitted to the lifting force pliers block, thereby achieving precise control of the endoscope surgical instrument;

[0037] The design of the convex structure and the groove structure also allows the lifting force pliers block to be easily separated from the lifting force pliers block when disassembling the disposable detachable distal cap, facilitating replacement and cleaning.

[0038] In a preferred example, the tip seat cap is made of a transparent material to facilitate observing the working state of the endoscope.

[0039] In a preferred example, the disposable detachable distal cap further includes a waterproof sealing ring provided on the tip seat cap for preventing 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 forceps block when it rotates to a preset angle.

[0041] In a preferred example, corresponding marks are provided on the end seat assembly and the disposable detachable distal cap for indicating the correct connection position.

[0042] In a preferred example, the operating mechanism includes:

[0043] A pull rod assembly, and the pull rod assembly includes:

[0044] a) A pull rod disposed in the end seat, and the pull rod can move longitudinally;

[0045] b) An elastic element connected to the pull rod for providing a return force to 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 engage with a corresponding structure inside the disposable detachable distal cap when the disposable detachable distal cap is connected to the end seat assembly, for controlling the 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) Reducing the risk of infection: During the reuse process of traditional duodenoscopes, due to their structural design, reprocessing is difficult. Once the processing is improper, cross-infection may occur. Through the design of the disposable detachable distal cap in the present application, a new distal cap can be replaced after each use, avoiding the entry of residual tissue or body fluid on the instrument into others' bodies, thereby significantly reducing the risk of infection.

[0050] 2) Simplifying the reprocessing process: Since the distal seat and the lifting forceps of traditional endoscopes are connected by pins, and the end seat cap and the end seat are adhered together, the reprocessing is very complex and time-consuming. The end seat assembly and the disposable detachable distal cap in the present application are connected by a snap structure, and the installation and disassembly are very convenient, greatly simplifying the reprocessing process and improving the use efficiency.

[0051] 3) Improve operation convenience: Through the docking of the lifting forceps block and the lifting forceps piece, the operation control of the endoscope is realized in this application. The lifting forceps block can rotate within the range of 0° to 90°, driving the synchronous rotation of the lifting forceps piece, thereby controlling the angle of the medical device inside the endoscope. This design not only improves the flexibility and accuracy of operation but also enhances the convenience of use.

[0052] 4) Maintain sealing and waterproof performance: In the design of this application, the sealing performance of the connection is ensured through structures such as sealing rings to prevent pollutants from entering the interior. At the same time, the tip seat cap is made of transparent material, facilitating the observation of the working state of the endoscope, and through the waterproof sealing ring design, preventing liquid from entering the interior of the endoscope, ensuring the normal use of the device.

[0053] 5) Equipment maintenance and cost control:

[0054] Due to the detachable design of this application, the end part seat assembly can be reused, and the disposable distal cap can be conveniently replaced. This not only reduces the complexity and cost of equipment maintenance but also improves the service life and economic benefits of the equipment.

[0055] Through the innovative detachable design, this application significantly simplifies the reprocessing process while ensuring aseptic operation and reducing the risk of infection, improving the operation convenience and the economy of equipment maintenance. These technical effects ensure the practicality and application value of this application in the field of endoscopes.

[0056] A large number of technical features are recorded in the specification of this application, distributed in various technical solutions. If all possible combinations of technical features (i.e., technical solutions) of this application are to be listed, the specification will become overly long. To avoid this problem, each technical feature disclosed in the above-mentioned utility model content, each technical feature disclosed in the following embodiments and examples, and each technical feature disclosed in the drawings can be freely combined with each other to form various new technical solutions (these technical solutions are all regarded as having been recorded in this specification), unless the combination of such technical features is technically infeasible. For example, in one example, features A + B + C are disclosed, and in another example, features A + B + D + E are disclosed, and features C and D are equivalent technical means that play the same role and only one of them can be used technically and they cannot be used simultaneously. Feature E can be combined with feature C technically. Then, the solution of A + B + C + D should not be regarded as having been recorded due to technical infeasibility, while the solution of A + B + C + E should be regarded as having been recorded.

[0103] To make the objectives, technical solutions, and advantages of this application clearer, the following will further describe in detail the embodiments of this application with reference to the accompanying drawings.

[0104] First Embodiment

[0105] See 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 cap 2 detachably connected to the end seat module 1 through a connection structure that maintains sealing in the connected state.

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

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

[0108] And, the transmission mechanism arranged inside the end seat 1-1 and connected to the pliers lifting block 1-7 is used to drive the pliers lifting block 1-7 to rotate.

[0109] On the other hand, the disposable detachable distal cap 2 includes: a tip seat cap 2-1, and a pliers lifting piece 2-2 arranged inside the tip seat cap 2-1.

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

[0111] It should be noted that when the pliers lifting block 1-7 rotates to the 0° position, the disposable detachable distal cap 2 can be detached from the end seat module 1, facilitating the replacement of a new disposable detachable distal cap 2.

[0112] Specifically, this embodiment proposes a detachable sterile protection structure for an electronic endoscope. This structure mainly consists of two parts: an end seat module 1 and a disposable detachable distal cap 2. These two parts are detachably connected together through a connection structure that maintains sealing in the 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 for providing a return force to 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] Wherein, the distal end of the pull rod 1-2 is designed to engage with a corresponding structure inside the disposable detachable distal cap 2 when the disposable detachable distal cap 2 is connected to the end seat module 1, for controlling additional functions of the endoscope.

[0127] Specifically, as Figures 3 - 5 shown, the transmission mechanism includes: a gear set disposed inside the end seat 1-1, including a conversion gear 1-9; and an operating mechanism disposed 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 drivingly connected to the forceps lifting block 1-7 through the gear set for driving the forceps lifting block 1-7 to rotate within a 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 inside the end seat 1-1, the pull rod 1-2 being capable of moving longitudinally; a return spring 1-3 connected to the pull rod 1-2 for providing a return force to 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 a rotational movement through the gear set and transmits the rotational movement to the forceps lifting block 1-7. Through this design, the forceps lifting block 1-7 can rotate precisely within a range of 0° to 90°, thereby achieving precise control of the angle of the medical device during the operation of the endoscope.

[0130] When the disposable detachable distal cap 2 is connected to the end seat module 1, the distal end of the pull rod 1-2 can engage with a corresponding structure inside the disposable detachable distal cap 2. At this time, each 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 block 1-7. This design not only ensures the high efficiency and reliability of the transmission mechanism, but also greatly simplifies the complexity of the endoscope operation and improves the convenience of use of the device.

[0131] More specifically, optionally, 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 longitudinally it is designed as an inclined rack structure. This composite design precisely meshes with the conversion gear 1-9, forming an efficient rack-and-gear 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 during longitudinal movement. At the same time, the inclined rack structure on its surface is the key to realizing motion conversion. When the pull rod 1-2 moves longitudinally, this inclined rack part can effectively drive the conversion gear 1-9 to rotate, thus precisely converting the linear motion of the pull rod into the rotational motion of the gear.

[0133] The advantages of this are as follows: 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 tooth pitch, and the size of the gear, the conversion ratio from linear motion to rotational motion can be precisely controlled, achieving precise adjustment of the angle of the endoscopic surgical instrument. 3) Connection stability: The trapezoidal cross-section design enhances the meshing stability between the pull rod and the gear, ensuring that there is no slippage or disengagement during the transmission process, providing a reliable transmission connection. 4) Smooth transmission: The optimized rack-and-gear structure ensures the smoothness of the motion transmission process, effectively reducing vibrations and noises during the transmission. 5) Compact design: This structure allows for complex motion conversion within 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-and-gear structure has higher durability and reliability and can withstand the wear of long-term use.

[0134] Through this innovative rack-and-gear design, the longitudinal motion of the pull rod 1-2 can be efficiently and precisely converted into the rotational motion of the conversion gear 1-9, and then transmitted to the lift clamp block 1-7 through the gear set, achieving 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 enhancing the usability and overall performance of the endoscope.

[0135] Through the above design, this embodiment realizes precise control of the lift clamp block 1-7, enabling the lift clamp 2-2 to rotate synchronously, thereby improving the flexibility and precision 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, improving the usability and efficiency. This technical solution not only solves many problems encountered in the operation of traditional endoscopes but also significantly improves the performance and user experience of the device.

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

[0137] At least one groove structure matching the shape and size of the convex structure is provided on the forceps lifting block 2-2;

[0138] Wherein, when the disposable detachable distal cap 2 is connected to the end seat module 1, the convex structure can be accurately inserted into and slidably fitted in the groove structure to achieve reliable docking of the forceps lifting block 1-7 and the forceps lifting block 2-2;

[0139] This docking design ensures that the rotational movement of the forceps lifting 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 convex 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 cap 2 is disassembled, facilitating replacement and cleaning.

[0141] Specifically, as Figure 3 , Figure 7 and Figure 8 shown, at least one rectangular tab structure is provided at the end of the forceps lifting block 1-7, and its short side is tangent to the circumferential contour of the forceps lifting block. This rectangular tab structure is formed by cutting with a plane perpendicular to the axis, so that it has a flat surface for achieving precise transmission and positioning; at least one groove structure matching the shape and size of the convex structure is provided on the forceps lifting block 2-2. Wherein, when the disposable detachable distal cap 2 is connected to the end seat module 1, the convex structure can be accurately inserted into and slidably fitted in the groove structure to achieve reliable docking of the forceps lifting block 1-7 and the forceps lifting block 2-2. This docking design ensures that the rotational movement of the forceps lifting block 1-7 can be accurately transmitted to the forceps lifting block 2-2, thereby achieving precise control of the endoscopic surgical instrument; the design of the convex 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 cap 2 is disassembled, facilitating replacement and cleaning.

[0142] In other words, at least one convex structure is provided at the end of the lifting forceps shifting block 1-7. The design of the convex structure enables it to provide stable connection and transmission when docking with the lifting forceps block 2-2. At least one groove structure matching the shape and size of the convex structure is provided on the lifting forceps block 2-2. The design of the groove structure ensures that when the convex structure is inserted, an accurate sliding fit can be formed, guaranteeing the reliability of the docking. When the disposable detachable distal cap 2 is connected to the end seat module 1, the convex structure of the lifting forceps shifting block 1-7 can be accurately inserted and slidably fitted into the groove structure of the lifting forceps block 2-2. This docking design enables the lifting forceps shifting block 1-7 to drive the lifting forceps block 2-2 to rotate synchronously, achieving precise control of the endoscopic surgical instrument. Through the above docking design, the rotational movement of the lifting forceps shifting block 1-7 can be accurately transmitted to the lifting forceps block 2-2. This transmission not only ensures the operation accuracy of the endoscopic surgical instrument, but also improves the operation flexibility and reliability. The design of the convex structure and the groove structure also allows the lifting forceps shifting block 1-7 to be easily separated from the lifting forceps block 2-2 when the disposable detachable distal cap 2 is disassembled.

[0156] Specifically, the detachable sterile protection structure of the electronic endoscope in this embodiment further includes: at least one elastic sealing ring, the elastic sealing ring being of an annular structure, is disposed in the annular slot of the end seat 1-1 or on the annular block of the disposable detachable distal end cap 2. Wherein, the elastic sealing ring is made of a material having good elasticity and sealing performance, such as silicone rubber or fluororubber. When the disposable detachable distal end cap 2 is connected to the end seat module 1, the elastic sealing ring is compressed between the annular slot 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 of an annular structure and is specifically designed to form a sealing interface within the annular card slot of the end seat 1-1 or on the annular clamping block of the disposable detachable distal end cap 2. The setting position of the elastic sealing ring ensures effective prevention of the entry of external contaminants in the connected state. The elastic sealing ring is made of materials 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 the compressed state, thus ensuring the sterile environment of the endoscope. When the disposable detachable distal end cap 2 is connected to the end seat module 1, the elastic sealing ring is compressed between the annular card slot and the annular clamping block. The elastic sealing ring in the compressed state can form a reliable sealing interface to ensure the sealing effect at the connection. Whether during use or during cleaning and maintenance, 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, it is possible to further prevent external contaminants from entering the inside of the endoscope, thereby improving the safety and service life of the device.

[0159] Optionally, the end seat module 1 further includes a locking mechanism for locking the lifting forceps dial 1-7 when it rotates to a preset angle.

[0160] Specifically, referring to Figure 1 and Figure 6 , the end seat module 1 further includes a locking mechanism for locking the lifting forceps dial 1-7 when it rotates to a preset angle. The design of this locking mechanism ensures that the lifting forceps dial 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 for locking the lifting clamp block 1-7 when it rotates to a preset angle. The main function of the locking mechanism is to ensure that the lifting clamp 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 braking device. The locking pin can pop out and engage with the corresponding locking hole when the lifting clamp block 1-7 rotates to the preset angle, thereby fixing the lifting clamp block 1-7 at this angle. The gear braking device can lock the lifting clamp block 1-7 at the preset angle by means of gear engagement. When the lifting clamp block 1-7 rotates to the preset angle, the locking mechanism will be automatically activated to ensure the stability of the lifting clamp block 1-7. For example, when the lifting clamp block 1-7 rotates to 90°, the locking mechanism will lock it to prevent angle deviation caused by external forces during the operation. This design not only improves the operation accuracy but also enhances the safety performance of the device. When it is necessary to adjust the angle of the lifting clamp block 1-7, the user can release the locking mechanism through a specific operation, such as pressing a specific unlocking button or rotating a control knob to disengage the locking pin or the gear braking device from the locked state. This design facilitates the operator to quickly adjust the angle of the lifting clamp 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 clamp block 1-7 at the preset angle. The locking mechanism not only enhances the operation accuracy of the device but also improves the convenience and safety of use. During the endoscopic surgery process, the introduction of the locking mechanism can effectively prevent surgical risks caused by angle deviation and further ensure the smooth progress of the surgery.

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

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

[0164] More specifically, corresponding markings are provided on the end seat module 1 and the disposable detachable distal cap 2 respectively. These markings can be color markings, shape markings or text markings to help the user quickly align the correct position during connection. For example, markings of red and blue can be respectively set on the end seat 1-1 and the tip seat cap 2-1. When the two are aligned, it is the correct connection position. The marking on the end seat 1-1 is usually set in a conspicuous position for the user to observe and align during the installation process. Similarly, the marking on the tip seat cap 2-1 is also set in an obvious position so that the two can be conveniently aligned, thus achieving quick connection. These markings are used to indicate the correct connection position to ensure that when the disposable detachable distal cap 2 is connected to the end seat module 1, all components can be correctly docked and fixed. The correct connection position can ensure the reliable docking of the lift forceps block 1-7 and the lift forceps piece 2-2, ensuring the accuracy of transmission and operation. By setting these markings, when the user installs and disassembles the disposable detachable distal cap 2, there is no need to perform cumbersome alignment operations, and only need to align the markings to complete the installation. This not only improves the convenience of use, but also reduces the possibility of incorrect installation, thereby improving the use efficiency and safety of the device. The design of these markings should be clear and easy to understand and can be clearly seen under different light conditions. Common designs include markings with strong color contrast, raised or sunken shape markings, and arrow markings with indicating directions. Through this design, it is ensured that even in a tense surgical environment, the user can quickly and accurately complete the connection.

[0165] Through the above design, this embodiment provides a convenient and fast marking system for indicating the correct connection position between the disposable detachable distal cap 2 and the end seat module 1. These markings not only improve the accuracy and convenience of connection, but also enhance the use safety of the device, preventing equipment failures or surgical risks caused by incorrect installation. While ensuring the functionality of the device, this design also greatly improves the operation experience of the user.

[0166] Optionally, the disposable detachable distal cap 2 further includes a waterproof sealing ring provided on the tip seat cap 2-1 for preventing liquid from entering the interior of the endoscope.

[0167] Specifically, optionally, the disposable detachable distal cap 2 further includes a waterproof sealing ring provided on the tip seat cap 2-1 for preventing liquid from entering the interior of the endoscope. The design of this waterproof sealing ring ensures that liquid will not seep 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 detachable distal cap 2 includes a waterproof sealing ring disposed on the tip seat cap 2-1. The main function of the waterproof sealing ring is to prevent liquid from entering the interior of the endoscope and protect the internal components of the device from liquid damage. The waterproof sealing ring is usually made of a durable material with high sealing performance, such as silicone rubber or fluororubber. The waterproof sealing ring is installed at the edge or inside of the tip seat cap 2-1. When connected to the end seat 1-1, the sealing ring can form a tight 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 device interior. When the disposable detachable distal cap 2 is connected to the end seat module 1, the waterproof sealing ring is compressed between the two to form an effective waterproof barrier. The sealing ring in this compressed state can block the liquid that may be generated during the operation and prevent it from entering the internal circuits and optical components of the endoscope. The setting of the waterproof sealing 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, it reduces equipment failures and damages caused by liquid intrusion and extends the service life of the device. 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 under high pressure and complex usage environments. The material selection 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 to ensure that the endoscope can effectively prevent liquid from entering the device interior during use. The setting of the waterproof sealing ring not only improves the protection performance of the device but also enhances the durability and service life of the device. This design not only guarantees the functionality of the device but also greatly improves the operating safety of the user and the reliability of the device.

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

[0170] Specifically, optionally, the tip seat cap 2-1 is made of a transparent material to facilitate observing the working state of the endoscope. The purpose of this design is to enable the operator to observe the working condition 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 glasses. The selection of transparent materials not only ensures the strength and durability of the cap, but also provides good optical transmission performance, enabling the operator to clearly observe the working state of the endoscope. Due to the transparent characteristics of the tip seat cap 2-1, the operator can directly observe the internal situation of the endoscope through the cap, such as the state of the internal optical components and electronic elements. This design allows the operator to check whether the endoscope is working properly at any time during the operation, and promptly discover and solve possible problems. Through the transparent tip seat cap 2-1, the operator can better monitor the working state of the endoscope, ensuring the stable operation of the device during the operation. This real-time monitoring ability greatly improves the safety of the operation and reduces the surgical risks caused by equipment failures. The selected transparent materials should have high transparency and excellent mechanical properties, such as impact resistance, abrasion resistance, and chemical corrosion resistance. Commonly used transparent materials include polycarbonate (PC), acrylic (PMMA), and optical glass, etc. 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 the transparent materials are crucial for 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 materials should also have good anti-reflection properties to reduce the reflection of light on the material surface, thereby improving the observation effect. Through the above design, the tip seat cap 2-1 of this embodiment is made of transparent materials, enabling the operator to observe the working state of the endoscope in real time. This design not only improves the monitoring ability and operation safety of the device, but also enhances the precision and reliability of the operation. The selection and application of transparent materials ensure the stable operation of the endoscope 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 portion seat assembly 1 drives the forceps 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 forceps lifting block 1-7. The rotation range of the forceps lifting block 1-7 is from 0° to 90°, thereby driving the forceps lifting block 2-2 inside the disposable detachable distal cap 2 to rotate synchronously.

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

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

[0176] Throughout the process, the waterproof seals and transparent tip seat cap 2-1 of the end seat assembly 1 and the disposable detachable distal cap 2 ensure the sealing and visibility of the device, enabling the operator to monitor the working state of the endoscope in real time and ensuring the safety and smoothness of the surgical process. At the same time, the locking mechanism ensures the stability of the forceps lifting block 1-7 during operation, prevents angle deviation, and improves the accuracy of operation.

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

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

[0179] 1) Reducing the risk of infection: In the process of reusing traditional duodenoscopes, due to their structural design, reprocessing is difficult. Once the processing is improper, cross-infection may occur. Through the design of the disposable detachable distal cap in the above embodiments, a new distal cap can be replaced after each use, avoiding the entry of residual tissue or body fluid on the instrument into others' bodies, thus significantly reducing the risk of infection.

[0180] 2) Simplifying the reprocessing process: Since the distal seat and forceps lifter of traditional endoscopes are connected by pins, and the end seat cap is adhered to the end seat, the reprocessing is very complex and time-consuming. The end seat assembly and the disposable detachable distal cap in the above embodiments are connected by a snap structure, which is very convenient for installation and disassembly, greatly simplifies the reprocessing process, and improves the use efficiency.

[0181] 3) Improve operation convenience: Through the docking of the lifting force pliers block and the lifting force pliers, the above embodiments realize the operation control of the endoscope. The lifting force pliers block can rotate within the range of 0° to 90°, driving the lifting force pliers to rotate synchronously, thereby controlling the angle of the medical device inside the endoscope. This design not only improves the flexibility and accuracy of operation, but also enhances the convenience of use.

[0182] 4) Maintain sealing and waterproof performance: In the above embodiments, the sealing performance of the connection is ensured through structures such as sealing rings to prevent pollutants from entering the interior. At the same time, the tip seat cap is made of transparent material, which is convenient for observing the working state of the endoscope, and through the waterproof sealing ring design, it prevents liquid from entering the interior of the endoscope, ensuring the normal use of the device.

[0183] 5) Equipment maintenance and cost control:

[0184] Due to the detachable design of the above embodiments, the end portion seat assembly can be reused, and the disposable distal cap can be conveniently replaced. This not only reduces the complexity and cost of equipment maintenance, but also improves the service life and economic benefits of the equipment.

[0185] Through the innovative detachable design, the above embodiments significantly simplify the reprocessing process while ensuring aseptic operation and reducing the risk of infection, improving the operation convenience and the economy of equipment maintenance. These technical effects ensure the practicality and application value of the above embodiments in the field of endoscopes.

[0186] In order to better understand the technical solution of the present application, a specific example will be described below. The details listed in this example are mainly for the convenience of understanding and do not limit the protection scope of the present application.

[0187] Such as Figure 1 、 Figure 2As shown in the figure, the detachable sterile protection structure of the electronic endoscope in this example includes: an end seat assembly 1 and a disposable detachable distal cap 2. The lifting forceps dial block 1-7 of the end seat module can rotate within the range of 0° - 90° driven by the 1-2 pull rods, and the lifting forceps block 2-2 of the disposable detachable distal cap 2 can rotate within the range of 0° - 90° driven by the lifting forceps dial block 1-7. When the lifting forceps dial block 1-7 of the end seat assembly rotates to the 0° position, the lifting forceps block 2-2 of the disposable detachable distal cap also rotates to the 0° position, and the 2 disposable detachable distal caps can be sleeved onto the end seat assembly 1. At this time, the lifting forceps dial block 1-7 of the end seat assembly can drive the lifting forceps block 2-2 of the disposable detachable distal cap to rotate synchronously within the range of 0° - 90°. After use, when the lifting forceps dial block 1-7 of the end seat assembly rotates to the 0° position, the disposable detachable distal cap 2 can be disassembled. After disassembly, the end seat assembly 1 is convenient for reprocessing, and when reused, only a new 2 disposable detachable distal cap needs to be replaced to achieve the effect of single use.

[0188] As Figure 3 , Figure 4 , Figure 5 shown, the detachable sterile protection structure of this endoscope is subdivided into: an end seat 1-1, a pull rod 1-2, a return spring 1-3, a limit rod 1-4, a positioning tube 1-5, a lifting forceps dial block seal ring 1-6, a lifting forceps dial block 1-7, a lifting forceps dial block positioning wheel bearing 1-8, a conversion gear 1-9, a gear retaining piece 1-10, a sealing piece 1-11, a sealing plug 1-12, a distal end seat cap 2-1, and a lifting forceps block 2-2. The end seat 1-1 is the main load-bearing part in the assembly, and other parts are assembled with it as the main body. First, the lifting forceps dial block seal ring 1-6, the lifting forceps dial block 1-7, and the lifting forceps dial block positioning wheel bearing 1-8 are tightly fitted and sequentially installed into the side holes of the end seat 1-1. Then, the pull rod 1-2, the return spring 1-3, the limit rod 1-4, and the positioning tube 1-5 are sequentially installed, and then the conversion gear 1-9 (matched with the pull rod 1-2), the gear retaining piece 1-10, the sealing piece 1-11 (sealingly and fixedly connected to the end seat 1-1), and the sealing plug 1-12 are installed. At this time, the end seat assembly 1 is complete. The lifting forceps block 2-2 is installed into the rotating hole of the distal end seat cap 2-1 to complete the disposable detachable distal cap 2.

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

[0190] As Figure 4 , Figure 5As shown, the pliers-lifting block sealing ring 1-6 is installed in the side hole of the end seat 1-1 (sealing with the side hole of the end seat 1-1), the pliers-lifting block 1-7 is installed in the hole of the pliers-lifting block sealing ring 1-6 (with the functions of rotation and sealing), the pliers-lifting block positioning wheel bearing 1-8 is sleeved on the pliers-lifting block 1-7 and is tightly and fixedly fitted with the side hole of the end seat 1-1, the conversion gear 1-9 is sleeved in the square hole of the pliers-lifting block 1-7 and is in embedded fit (the conversion gear 1-9 drives the pliers-lifting block 1-7 to rotate together), the gear retaining piece 1-10 (prevents the conversion gear 1-9 from moving axially), and the sealing piece 1-11 (is brazed and sealed and fixed with the end seat 1-1).

[0191] The working principle of this example is as follows:

[0192] During use, the end seat assembly 1 drives the pliers-lifting block 1-7 to rotate through the internal transmission mechanism. 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 pliers-lifting block 1-7. The rotation range of the pliers-lifting block 1-7 is from 0° to 90°, thereby driving the pliers block 2-2 in the disposable detachable distal cap 2 to rotate synchronously.

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

[0194] After use, the pliers-lifting block 1-7 rotates to the 0° position again, and the user can easily disassemble the disposable detachable distal cap 2. Through this design, the end seat assembly 1 can be conveniently reprocessed, and only a new disposable detachable distal cap 2 needs to be replaced during reuse, achieving the effect of single use and avoiding the risk of cross-infection.

[0195] Throughout the process, the waterproof sealing rings of the end seat assembly 1 and the disposable detachable distal cap 2 and the transparent tip seat cap 2-1 ensure the sealing and visibility of the device, enabling the operator to monitor the working state of the endoscope in real time and ensuring the safety and smoothness of the surgical process. At the same time, the locking mechanism ensures the stability of the pliers-lifting block 1-7 during operation, prevents angle deviation, and improves the accuracy of operation.

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