Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to an endoscope imaging technology. Background Art

[0002] An endoscope is a medical device used for medical diagnosis and treatment. By introducing an optical imaging system and a lighting system into the human body, images of internal organs and tissues can be obtained, providing intuitive visual information for doctors to diagnose diseases and perform minimally invasive surgery. Since the advent of endoscope technology in the 1950s, it has been widely used in many clinical fields such as gastrointestinal, respiratory, urological, and gynecological.

[0003] Traditional endoscopes usually use the axial imaging method, that is, the optical axis of the imaging lens is parallel to the axis of the insertion part of the endoscope. This type of endoscope can also be called a linear endoscope. Although this imaging method has a simple structure, it has a limited field of view and is difficult to achieve ideal imaging effects in some application scenarios.

[0004] Therefore, it is necessary to improve and optimize the structure of the endoscope, propose a new endoscope module, adopt a more reasonable lens installation method and lighting layout, and simplify the overall structure of the endoscope, in order to obtain better imaging effects, improve the availability and reliability of the endoscope, reduce production costs, and promote the further development of endoscope technology. Utility Model Content

[0005] The purpose of the utility model is to provide an endoscope module to solve the problems raised in the above-mentioned background technology.

[0006] The present application discloses an endoscope module, comprising:

[0007] An endoscope lens, disposed at the front end of the endoscope module, for capturing images, the endoscope lens having an optical axis;

[0008] A head end seat, the front end of which comprises an upper inclined surface and a lower inclined surface, wherein the upper frame and the lower frame of the endoscope lens are in contact with the upper inclined surface and the lower inclined surface respectively, so that the endoscope lens is fixedly connected to the front end of the head end seat, and the endoscope lens is positioned so that its optical axis forms a preset angle of 30°-60° with the axial direction of the head end seat;

[0009] A housing, coaxially connected to the head end seat, surrounding the rear end of the head end seat, for providing protection and cooperating with handheld operation;

[0010] LED lights are arranged on the left and right sides of the endoscope lens to provide lighting;

[0011] A flexible circuit board is electrically connected to the endoscope lens and is used to transmit image signals.

[0012] In a preferred example, the optical axis of the endoscope lens forms a preset angle of 30° with the axial direction of the head end seat.

[0013] In a preferred embodiment, a space for accommodating surgical instruments is provided on the lower inclined surface of the head end seat, the space is located below the endoscope lens, and the surgical instruments are selected from the following group: biopsy forceps, strong grasping forceps, double-opening straight scissors, and single-opening micro scissors.

[0014] In a preferred example, the angle between the upper inclined surface of the front end of the head end seat and the axial direction is 124°-150°, and the angle between the lower inclined surface of the front end of the head end seat and the axial direction is 100°-130°.

[0015] In a preferred example, the LED lights are a pair of LED lights arranged symmetrically on both sides of the endoscope lens.

[0016] In a preferred example, the maximum width of the endoscope lens ranges from 1.15 mm to 1.48 mm.

[0017] Compared with the prior art, the embodiments of the present invention have at least the following differences and effects:

[0018] First, the endoscope lens of the utility model forms an angle of 30-60 degrees with the axial direction of the head end seat, so that the lens field of view is skewed. Compared with the traditional direct-view endoscope, this oblique design can effectively observe the inner wall of the human cavity and the side of the organ, expanding the observation range. At the same time, by rotating the endoscope, the field of view direction can be flexibly changed, and different parts can be observed in an all-round way, reducing blind spots and improving the accuracy of diagnosis and treatment.

[0019] Furthermore, the endoscope head of the utility model adopts a carefully designed head end seat, the edges of which are rounded to avoid irritation and damage to human mucosa and tissues by sharp corners. The head end seat is made of smooth, corrosion-resistant medical materials, and the surface is polished or coated to minimize trauma to the human body during insertion and rotation. At the same time, the close fit between the head end seat and the housing and sleeve also effectively prevents the entry of cavity liquid and dirt, ensuring the cleanliness and safety of the endoscope.

[0020] Furthermore, the inclined surface above the endoscope lens of the utility model is not only used to fix the lens, but also has the function of supporting the inner wall of the cavity. During the insertion process, the inclined surface can gently open the cavity, broadening the field of vision and operating space. At the same time, the inclined surface also has a guiding function, facilitating the smooth advance and retreat of the endoscope along the cavity direction. This ingenious structural design not only improves the observation effect, but also provides convenience for endoscopic treatment operations.

[0021] In summary, the endoscope module provided by the utility model has achieved remarkable results in expanding the field of view, improving observation flexibility, protecting human tissue, and improving operational convenience through a number of optimization measures such as oblique-angle lenses, rounded head ends, supporting bevels, and integrated design. It has very broad application prospects in the fields of medical diagnosis and treatment.

[0022] The specification of the utility model records a large number of technical features, which are distributed in various technical solutions. If all possible combinations of technical features of the utility model (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 utility model 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 such a combination of 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.

[0038] First embodiment

[0039] See also Figure 1 The endoscope module of this embodiment includes:

[0040] An endoscope lens 10, disposed at the front end of the endoscope module, for capturing images, and the endoscope lens 10 has an optical axis;

[0041] A head end seat 20, the front end of which includes an upper inclined surface 20a and a lower inclined surface 20b, wherein the upper frame and the lower frame of the endoscope lens 10 are in contact with the upper inclined surface 20a and the lower inclined surface 20b respectively, so that the endoscope lens 10 is fixedly connected to the front end of the head end seat 20, and the endoscope lens 10 is positioned so that its optical axis forms a preset angle of 30°-60° with the axial direction of the head end seat 20;

[0042] The housing 30 is coaxially connected to the head end base 20 and surrounds the rear end of the head end base 20 to provide protection and cooperate with hand-held operation;

[0043] LED lights 40 are symmetrically arranged on the left and right sides of the endoscope lens 10 to provide lighting;

[0044] The flexible circuit board 50 is electrically connected to the endoscope lens 10 and is used to transmit image signals.

[0045] Optionally, the endoscope module of this embodiment further includes an outer sleeve and an inner sleeve, wherein the outer sleeve structure cooperates with the outer shell 30 to enhance the overall strength of the module, and the inner sleeve is arranged in the head end seat 20 and is equipped with a wiring harness channel for organizing and protecting the wiring harness extending from the flexible circuit board 50.

[0046] Optionally, the optical axis of the endoscope lens 10 forms a preset angle of 30° with the axial direction of the head end seat 20 .

[0047] The present embodiment is further explained below.

[0048] Endoscope lens 10:

[0049] Optionally, the endoscope lens 10 adopts a wafer-level optical lens, and the size can be made very small, for example, the maximum width ranges from 1.15 mm to 1.48 mm.

[0050] The endoscope lens 10 is located at the front end of the endoscope module. Its function is to collect optical images of internal organs and tissues of the human body and transmit them to the image processing and display system at the back end. The endoscope lens 10 is usually composed of a plurality of lenses, including an objective lens, an intermediate lens group and an eyepiece. By reasonably designing the structural parameters and arrangement of the lens, an imaging effect with high resolution, low distortion and large depth of field can be obtained.

[0051] In this embodiment, the endoscope lens 10 has its own optical axis.

[0052] Optionally, the endoscope lens 10 and the flexible circuit board 50 are electrically connected and fixed by welding.

[0053] The endoscope lens 10 and the head end seat 20 are installed in a matching manner so that the optical axis of the endoscope lens 10 forms a certain angle, for example, 30°-60°, relative to the axial direction of the head end seat 20. This "squint" optical design can broaden the field of view of the endoscope, so that it is not limited to the area directly in front, but can observe the side of the organ wall, which is conducive to comprehensive and accurate diagnosis.

[0054] At the same time, the endoscope lens 10 and the head end seat 20 are embedded, and the upper and lower frames of the lens are respectively fitted with the upper inclined surface 20a and the lower inclined surface 20b of the head end seat 20. The structure is compact, the force is evenly distributed, the fixation is reliable, and it is not easy to produce relative movement or looseness.

[0055] Head end seat 20:

[0056] The head end seat 20 is cylindrical in shape as a whole, but its front end (the end close to the endoscope lens 10 ) is not straight, but forms two upper and lower inclined surfaces to accommodate and fix the endoscope lens 10 .

[0057] Optionally, the upper bevel 20a has an axial angle of about 124°-150° with the head end seat 20, and is used to connect to the upper frame of the endoscope lens 10; the lower bevel 20b has an axial angle of about 100°-130°, and is connected to the lower frame of the lens.

[0058] Optionally, the optical axis of the endoscope lens 10 forms an angle of 30°-60° with the axial direction of the head end seat 20. In a preferred embodiment, the angle is 30°. In this case, the maximum peripheral dimension of the endoscope can be minimized while ensuring a good field of view, so as to ensure that the outer diameter of the endoscope product is small.

[0059] The upper frame of the endoscope lens 10 is connected to the upper inclined surface 20a of the head end seat 20, and the lower frame of the endoscope lens 10 is connected to the lower inclined surface 20b of the head end seat 20, so that the endoscope head presents an oblique angle.

[0060] The inclined design of the upper and lower slopes 20b promotes smooth contact between the endoscope module and surrounding tissues, reducing the risk of damage to patient tissues.

[0061] Furthermore, this innovative design of the head end seat 20 improves the clinical application performance of the endoscope by optimizing the viewing angle of the endoscope lens 10, provides a better operating experience and observation conditions, and also increases the safety of the lens in contact with the surrounding tissue, and effectively reduces the space required for the head of the endoscope. In addition, the design of the entire endoscope not only ensures functionality, but also pays attention to the comfort and medical safety of the patient, reflecting a high degree of ergonomic considerations.

[0062] Optional, such as Figure 2 and Figure 3 As shown, a space is also provided on the lower inclined surface 20b of the head end seat 20, and the space is located below the endoscope lens 10. This space can be used to accommodate minimally invasive surgical instruments, such as biopsy forceps, strong grasping forceps, double-open straight scissors, single-open micro scissors and other surgical instruments.

[0063] This ingenious layout makes full use of the limited space under the endoscope head, and provides the possibility of integrating minimally invasive treatment functions into the endoscope without increasing the overall size of the module. By introducing the treatment instrument into this space and extending it from the front end of the head end seat 20, the diseased tissue can be accurately treated under direct endoscope vision, simplifying the surgical operation process and reducing the risk of complications.

[0064] At the same time, the transition design of the lower bevel 20b also facilitates the introduction of therapeutic instruments. The instruments can be introduced from the rear of the housing 30 along the inner cavity of the head end seat 20, and extend from the front end of the head end seat 20 after being guided by the lower bevel 20b, achieving flexible and controllable movement.

[0065] SHELL 30:

[0066] like Figure 2 and Figure 4 As shown, the housing 30 is a hollow cylindrical structure with one end open, and the inner diameter of the open end matches the outer diameter of the other end of the head end seat 20 to achieve smooth assembly of the two. The rear outer diameter of the head end seat 20 is precisely matched with the inner diameter of the front opening of the housing 30 to ensure coaxial connection and improve the concentricity of the endoscope module.

[0067] like Figure 1 and Figure 4 As shown, the housing 30 is a hollow cylindrical structure, and its axial direction is coaxial with the head end seat 20. One end of the housing 30 is open and surrounds the rear end of the head end seat 20, while the other end is closed. The head end seat 20 fits tightly with the housing 30, and coaxial fixation is achieved by matching connection to ensure that the endoscope module has good coaxiality. The housing 30 protects the rear part and internal components of the head end seat 20, and provides a suitable gripping surface for handheld operation.

[0068] Optionally, the connection method between the head end seat 20 and the housing 30 can be selected and optimized according to specific needs.

[0069] Optionally, an optional solution is to use interference fit, that is, the outer diameter of the rear part of the head end seat 20 is slightly larger than the inner diameter of the opening of the shell 30, and a close fit is achieved by pressing in, and a reliable fixation is achieved by friction. This connection method has the advantages of simple structure and high assembly efficiency.

[0070] Alternatively, another option is to add a medical adhesive to the sleeve joint, and firmly connect the head end seat 20 and the shell 30 as a whole by bonding. Compared with interference fit, the bonding connection strength is higher and not easy to loosen, but the assembly process requires more time and effort.

[0071] In practical applications, the appropriate connection method can be flexibly selected based on factors such as the use environment, performance requirements, and production costs of the endoscope module.

[0072] Optionally, the shell 30 can be made of high-strength, corrosion-resistant medical-grade stainless steel or titanium alloy or other metal materials to meet the use requirements of the endoscope in the complex environment of the human body. The surface is polished or coated, which can not only improve the appearance quality, but also reduce the risk of irritation and damage to human tissues and improve the comfort of patients.

[0073] LED Light 40:

[0074] The endoscope module of the present invention cleverly utilizes the limited space between the endoscope lens 10 and the head end seat 20, and sets an LED lamp 40 for lighting. Specifically, the LED lamp 40 is located on the endoscope lens 10 and is arranged on the left and right sides of the lens.

[0075] This layout of LED lights 40 fully utilizes the space in the endoscope head, and achieves efficient lighting without increasing the overall size of the module. The left and right distributed LED lights 40 can evenly illuminate the area in front of and around the endoscope lens 10, eliminating blind spots in the field of vision and improving image quality.

[0076] Optionally, the LED lamp 40 selected in this embodiment has the advantages of small size, high brightness, low power consumption, long life, etc. The compact package size is convenient for integration in a small space, and the excellent optical performance ensures that the endoscope obtains clear images in a complex human body environment.

[0077] The circuit connection of the LED lamp 40 has also been optimized. The lamp bead is reliably connected to the flexible circuit board 50 through micro leads, and the brightness adjustment and switch control are achieved through the control circuit on the circuit board. The streamlined wiring solution reduces the complexity of the connection and improves the reliability of the endoscope module.

[0078] Flexible circuit board 50:

[0079] The flexible circuit board 50 is used to realize the functions of image signal transmission and electrical interconnection. The endoscope lens 10 is electrically connected and fixed to the flexible circuit board 50 by welding to form a highly integrated imaging unit.

[0080] Optionally, micro welding technology, such as hot pressing welding or laser welding, can be used to achieve reliable connection between the endoscope lens 10 and the flexible circuit board 50 while minimizing the size of the solder joint and reducing the impact on the imaging quality of the lens.

[0081] The welded endoscope lens 10 and the flexible circuit board 50 form a compact imaging module, which can be easily assembled with the head end seat 20, simplifying the assembly process of the endoscope module. At the same time, the bending resistance of the flexible circuit board 50 enables it to adapt to the limited space of the endoscope lens head, thereby optimizing the spatial layout.

[0082] The flexible circuit board 50 integrates an image sensor interface circuit, a signal conditioning circuit, and other necessary electronic components for converting the analog image signal collected by the endoscope lens 10 into a digital signal, and transmitting it to the main control unit of the endoscope via a flexible cable for subsequent processing and display.

[0083] In summary, the flexible circuit board 50 serves as an electrical connection link for endoscope imaging and lighting. Its reliable welding with the endoscope lens 10 and its optimized design play a decisive role in improving the performance and reliability of the endoscope module.

[0084] Assembly and fixing:

[0085] The assembly process of the endoscope module requires strict sequence and precise alignment to ensure seamless fit and reliable fixation between the various components. The endoscope lens 10 and the flexible circuit board 50 after welding are first assembled with the head end seat 20 to form the core imaging unit of the endoscope module.

[0086] The head end seat 20 is made of precision machined metal material, and is provided with a mounting groove and a fixing structure matching the endoscope lens 10 and the flexible circuit board 50. Optionally, the lens and the circuit board are firmly fixed on the head end seat 20 by means of snaps, screws or bonding, and the optical axis and the axial direction of the head end seat 20 are ensured to maintain a preset angle.

[0087] The assembled endoscope core imaging unit is further assembled with the housing 30 to form a complete endoscope module. Optionally, the housing 30 is lightweight, made of high-strength engineering plastics or metal materials, and surface-treated to have good corrosion resistance and wear resistance. Optionally, the housing 30 is coaxially connected to the head end seat 20 in a precise matching manner, and a variety of connection methods such as thread, snap or glue can be selected to ensure the reliability of the connection and consider the convenience of assembly and maintenance.

[0088] Working principle:

[0089] The endoscope module of this embodiment utilizes a unique optical design and structural layout to achieve all-round observation and high-quality imaging of the inner wall of the human cavity.

[0090] The endoscope lens 10, as the core imaging device of the module, is arranged at the front end of the head end seat 20. Unlike traditional endoscopes, the optical axis of the lens is at a certain angle (30°-60°) to the axial direction of the head end seat 20, so that the field of view of the lens is tilted. This tilted viewing angle design expands the field of view of the endoscope, enabling it to observe the image information of the side wall of the cavity and reduce the blind spot during use. By rotating the endoscope, the doctor can flexibly change the viewing angle of the lens, obtain images of different areas in the cavity, and achieve panoramic observation.

[0091] In order to obtain clear images, the endoscope module also integrates an efficient LED lighting system. The LED lights 40 are cleverly arranged on the left and right sides of the lens. This layout makes full use of the limited space and achieves uniform illumination of the inner wall of the cavity without blocking the lens field of view. At the same time, the brightness of the LED light 40 can be adjusted by the control circuit to meet different observation needs. The optimized light guide design and the selection of optical materials effectively reduce problems such as glare and light spots, ensuring the overall quality of the image.

[0092] The head end seat 20 of the endoscope module not only has the function of fixing the endoscope lens 10, but its unique inclined surface design also plays a role in expanding and supporting the human cavity. The upper inclined surface 20a and the lower inclined surface 20b at the front end of the head end seat 20 are like a pair of wedges. During the insertion of the endoscope, they can appropriately open the cavity wall to widen the field of vision and operating space. At the same time, the smooth surface treatment and rounded edge design minimize the stimulation and damage to human tissues and improve the comfort of patients.

[0093] The housing 30 of the endoscope module provides reliable protection for the internal precision components. The housing 30, made of medical-grade materials, has excellent strength, corrosion resistance and insulation properties, can effectively isolate external pollution and withstand certain external forces. The outer sleeve is closely matched with the housing 30, which further enhances the protective performance of the endoscope and is also convenient for cleaning and disinfection. The humanized appearance design not only improves the aesthetics of the endoscope, but more importantly, reduces the psychological pressure on patients and improves the compliance of the examination.

[0094] In summary, the endoscope module of this embodiment realizes efficient observation and imaging of human cavities through the optimized design and coordinated work of multiple components such as the optical system, lighting system, head end seat 20 and housing 30, effectively broadens the field of view of the endoscope, improves image quality, and reduces blind spots during use. The carefully designed ergonomic features maximize the user experience and comfort of both doctors and patients. These optimized design concepts and technical solutions provide more advanced and reliable tools for endoscopic examinations and surgeries, and have broad prospects for clinical application.

[0095] Application scenarios:

[0096] For example, the endoscope module according to some embodiments of the utility model has unique advantages in gynecological hysteroscopy. There are anatomical bends and folds near the fallopian tube at the bottom of the uterus. It is difficult to directly observe these areas with traditional direct-view endoscopes, which easily lead to blind spots. Doctors often need to adjust the angle of the endoscope with force, or even push against the uterine wall to obtain an ideal field of view, but this may cause pain and discomfort to the patient and risk damaging the uterus.

[0097] The oblique endoscope lens designed in the utility model forms a certain angle with the axial direction of the head end seat. By rotating the endoscope, the viewing angle can be flexibly changed, and the hidden area at the bottom of the uterus can be easily observed, avoiding the situation of forcibly pressing the uterus. At the same time, the head end seat has a rounded and smooth appearance, which reduces the stimulation and damage to the endometrium. The upper inclined surface of the endoscope lens can also serve as a support, opening the uterine cavity and further improving the observation conditions. In short, the utility model can effectively broaden the field of view, reduce blind spots, improve diagnosis and treatment efficiency and patient comfort in gynecological hysteroscopy, and at the same time maximize medical safety.

[0098] In addition to gynecological applications, the embodiments of the utility model can also be widely used in multiple clinical fields such as arthroscopy, otolaryngology, gastroscopy, and colonoscopy. Human cavities and lumens generally have complex structures such as bends and recesses. The field of view of traditional endoscopes is limited, and the advantages of strabismus endoscopes are fully reflected. The utility model is expected to further broaden the scope of application of endoscopes and play a greater role in the field of minimally invasive diagnosis and treatment.

[0099] The above implementation has the following technical effects:

[0100] 1) The endoscope lens of the above embodiment is at an angle of 30-60 degrees to the axial direction of the head end seat, so that the lens field of view is skewed. Compared with the traditional direct-view endoscope, this oblique design can effectively observe the inner wall of the human cavity and the side of the organ, expanding the observation range. At the same time, by rotating the endoscope, the field of view can be flexibly changed to observe different parts in an all-round way, reducing blind spots and improving the accuracy of diagnosis and treatment.

[0101] 2) The endoscope head of the above embodiment adopts a carefully designed head end seat, and its edges are rounded to avoid irritation and damage to human mucosa and tissues by sharp corners. The head end seat is made of smooth, corrosion-resistant medical materials, and the surface is polished or coated to minimize trauma to the human body during insertion and rotation. At the same time, the close fit between the head end seat and the housing and sleeve also effectively prevents the entry of cavity liquid and dirt, ensuring the cleanliness and safety of the endoscope.

[0102] 3) The inclined surface above the endoscope lens of the above embodiment is not only used to fix the lens, but also has the function of supporting the inner wall of the cavity. During the insertion process, the inclined surface can gently open the cavity, broadening the field of vision and operating space. At the same time, the inclined surface also has a guiding function, which facilitates the smooth advance and retreat of the endoscope along the cavity direction. This ingenious structural design not only improves the observation effect, but also provides convenience for endoscopic treatment operations.

[0103] 4) The endoscope module of the above embodiment adopts a highly integrated design, which compactly arranges the imaging, lighting, transmission and other functions in the limited space of the head end seat and the shell. The key components such as the endoscope lens, LED light, and flexible circuit board have been optimized and miniaturized to minimize the volume and diameter of the head. This not only reduces the space occupied by the endoscope head in the human body cavity and alleviates the patient's discomfort, but also facilitates the flexible passage of the endoscope in narrow and curved cavities, expanding the scope of application of the endoscope.

[0104] In summary, the endoscope module of the above embodiment has achieved remarkable results in expanding the field of view, improving observation flexibility, protecting human tissue, and improving operational convenience through multiple optimization measures such as oblique-angle lens, rounded head end seat, support slope, and integrated design. These advantages not only improve the performance and user experience of the endoscope, but also provide a more powerful tool for clinical diagnosis and treatment, and have broad application prospects.
