Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more particularly to an examination device. Background Technology

[0002] Endoscopes such as hysteroscopy, cystoscopy, gastroscopy, colposcopy, bronchoscopy, laparoscopy, colonoscopy, and laparoscopy are inserted into the human body from outside through the body's natural cavities to examine certain parts of the body.

[0003] Traditional endoscopes are gradually being phased out due to their high cost, inconvenient operation, lack of portability, and susceptibility to hospital-acquired infections. In the future, the trend towards consumable endoscopes will be towards disposable endoscopes. A complete endoscope system typically consists of a lens system, an operation and control system, an image processing system, and a display system. Among these, the operation and control system, image processing system, and display system are the most expensive. To reduce the cost of using disposable endoscopes, the operation and control system, image processing system, and display system are usually designed as reusable devices. This means that the operation and control system, image processing system, and display system are designed as independent or integrated products that do not require contact with the human body, while the lens system is treated as a disposable consumable.

[0004] However, existing disposable endoscopes still pose problems such as easy cross-infection and contamination of image processing devices, resulting in low safety. Summary of the Invention

[0046] In clinical medicine, endoscopes are commonly used to examine target locations within the human body's internal cavities. Due to the high cost, complex structure, cumbersome operation, and susceptibility to infection associated with traditional endoscopes, the development and use of disposable endoscopes have gradually emerged.

[0047] However, disposable endoscopes in related technologies have problems such as unhygienic use and easy cross-infection due to operator contact during use, fluid leakage, and incomplete postoperative disinfection.

[0048] In view of this, embodiments of this application provide an inspection device, which includes a detachably connected manipulator and an image processing device. By providing a receiving cavity in the grip portion of the manipulator, the image processing device is installed within the receiving cavity. The grip portion encloses the image processing device, isolating it from the external environment and ensuring its hygiene and cleanliness. Furthermore, by providing a flared section at the end of the grip portion away from the manipulator, the flow-guiding effect of the flared section prevents liquid on the outer wall of the grip portion from contaminating the image processing device, thus avoiding cross-contamination and improving the safety of the inspection device. Additionally, by providing a protrusion on the outer wall of the image processing device at the end away from the manipulator, the protrusion, in conjunction with the flared section, limits the position of the image processing device, ensuring its positional accuracy and improving the assembly precision of the inspection device.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] Figure 1 A perspective structural diagram of an inspection device provided in an embodiment of this application; Figure 2 for Figure 1 An exploded view of the inspection device in the diagram; Figure 3 A perspective structural diagram of another inspection device provided in the embodiments of this application; Figure 4 for Figure 3 Exploded view of the inspection device.

[0051] Reference Figures 1 to 4 As shown in the figure, this application embodiment provides an inspection device 1, which includes an operator 100 and an image processing device 200. The operator 100 and the image processing device 200 are detachably connected. The operator 100 can be a disposable part, and the image processing device 200 can be a reusable part. As the names suggest, the disposable part is the part that cannot be reused, while the reusable part is the part that can be used repeatedly.

[0052] As a single-use part, the manipulator 100 may include parts that enter the human body and contact (or may contact) the human skin and tissues; as a reusable part, the image processing device 200 may include parts that do not need to enter the human body and can be reused.

[0053] By assembling the operator 100 and the image processing device 200 into an inspection device 1, the operator 100 is a disposable part and the image processing device 200 is a reusable part. On the one hand, the risk of the operator 100 being contaminated and cross-infection is reduced, which can improve the safety of the inspection device 1. On the other hand, by reusing the image processing device 200, material waste is avoided and the cost of using the inspection device 1 is reduced.

[0054] For example, the operator 100 can be sealed in a sterile bag before use, while the image processing device 200 can be disinfected and sterilized before and after use to ensure that the inspection device 1 is clean and hygienic.

[0055] As a single-use component, the manipulator 100 may include an operating part 110 and a gripping part 120, with the gripping part 120 connected to one axial end of the operating part 110. In use, the manipulator 100 extends toward the human body, at least partially penetrating the target area within the body, while the gripping part 120 is used by the operator to hold it, thereby controlling the inspection device 1.

[0056] The gripping part 120 is inclined to the operating part 110. In other words, there is an angle between the axis of the gripping part 120 and the axis of the operating part 110 to meet the angle requirements of operation. While ensuring that the operating part 110 can enter or reach the target part of the human body, it also ensures the comfort of the operator's grip and meets the space requirements of the operator to operate the inspection device 1.

[0057] In some examples, the grip portion 120 and the operating portion 110 can be fixedly connected, and a fixed tilt angle is maintained between the grip portion 120 and the operating portion 110. For example, the included angle between the grip portion 120 and the operating portion 110 can be between 90° and 150°, and the included angle between the grip portion 120 and the operating portion 110 can be, for example, 100°, 110°, 120° or 130°.

[0058] In other examples, the grip 120 and the operating part 110 can be rotatably connected. The grip 120 and the operating part 110 can be connected together by a structure such as a pivot or hinge. The angle between the grip 120 and the operating part 110 can be adjusted according to the operating requirements. For example, the angle between the grip 120 and the operating part 110 can be adjusted between 90° and 150°. Furthermore, a damping structure can be provided to stabilize the grip 120 and the operating part 110 in the required tilt state.

[0059] Among them, reference Figure 1 or Figure 2 As shown, in some embodiments, the manipulator 100 associated with the examination device 1 can be an endoscope with a long, thin tube that extends into the body. For example, the manipulator 100 associated with the examination device 1 can be a neuroscope, urethroscopy, electrocautery, laparoscope, arthroscope, sinusoscope, laryngoscope, or other endoscope.

[0060] At this time, the operating part 110 of the manipulator 100 may include a main body 111 and a scope tube 112. The scope tube 112 is installed on the side of the main body 111 opposite to the grip part 120, and the scope tube 112 is used to insert into the target part of the body. In addition, the operating part 110 may also include a knob 113, which is rotatably installed on one axial end of the operating part 110. The main body 111, the knob 113, and the grip part 120 together constitute an operating handle, and the scope tube 112 and the operating handle together constitute the manipulator 100.

[0061] The distal end of the endoscope tube 112 is typically equipped with components such as a camera (not shown in the figure) and a light source (not shown in the figure). During surgery, the endoscope tube 112 is inserted into the body, the target area is illuminated by the light source, and the image of the target area is observed using the camera. The operating handle contains tubing components (not shown in the figure) and cables (not shown in the figure). The tubing components are used to allow fluid to enter and exit the endoscope tube 112 to meet the needs during the surgery. The cables are used to electrically connect to the camera, light source, etc. at the distal end of the endoscope tube 112 to enable the examination device 1 to observe local fine tissues inside the body.

[0062] The knob 113 is used to rotate the scope tube 112, thereby moving the camera mounted at the distal end of the scope tube 112 to facilitate observation of different areas of the target body. The knob 113 can be mounted on the end of the main body 111 facing the grip 120 (as shown in the figure), and the knob 113 can drive the scope tube 112 to rotate via a component mounted inside the main body 111; alternatively, the knob 113 can be mounted on the end of the main body 111 away from the grip 120, and the knob 113 is sleeved on the scope tube 112, directly driving the scope tube 112 to rotate.

[0063] For example, the main body 111 and the gripping part 120 can be fixedly connected, or the main body 111 and the gripping part 120 can be rotatably connected. Taking the fixed connection of the main body 111 and the gripping part 120 as an example, Figure 2 As shown, the housing of the main body 111 may include two parts: an upper shell 1111 and a lower shell 1112. The upper shell 1111 and the lower shell 1112 are detachably connected to facilitate the installation of components inside the main body 111. The lower shell 1112 and the gripping part 120 may be fixedly connected by means of bonding, welding or mechanical connection, or the lower shell 1112 and the gripping part 120 may be an integrally formed structure.

[0064] Since the endoscope tube 112 needs to enter the body, the operating handle needs to be held by the operator and may come into contact with the skin or internal tissues. Furthermore, the fluid entering and exiting the body passes through a liquid control component installed in the operating handle, and the electrical control component installed in the operating handle needs to be connected to the distal end of the endoscope tube 112. Therefore, in this embodiment, the endoscope tube 112 and the operating handle are used as disposable parts of the examination device 1, which can reduce or even avoid the risk of contamination or cross-infection of the endoscope tube 112 and the operating handle.

[0065] Reference Figure 3 or Figure 4 As shown, in some other embodiments, the manipulator 100 associated with the examination device 1 can be a dilator. In this case, the image processing device 200 serves as an endoscope, for example, a colposcope or a nasal endoscope. In this case, the operating part 110 of the manipulator 100 can include mating duckbill-shaped dilators 114. The dilators 114 are connected to the gripping part 120, and the dilators 114 and the gripping part 120 together constitute the manipulator 100, i.e., the dilator.

[0066] The expansion wings 114 mounted on the grip portion 120 can open and close relative to each other. The expansion wings 114 are used to insert into the vagina or nasal cavity and to open the corresponding area. As shown in the figure, the expansion wings 114 may include an upper expansion wing 1141 and a lower expansion wing 1142. The lower expansion wing 1142 is connected to the top of the grip portion 120. The upper expansion wing 1141 is rotatably connected to the lower expansion wing 1142, and the upper expansion wing 1141 is located above the lower expansion wing 1142. The upper expansion wing 1141 and the lower expansion wing 1142 can open and close relative to each other in the vertical direction.

[0067] For example, the lower expansion wing 1142 and the grip portion 120 can be fixedly connected, or the lower expansion wing 1142 and the grip portion 120 can be rotatably connected. Taking the fixed connection of the lower expansion wing 1142 and the grip portion 120 as an example, ... Figure 4 As shown, the lower expansion wing 1142 can be fixedly connected to the gripping part 120 by means of bonding, welding or mechanical connection, or the lower expansion wing 1142 and the gripping part 120 can be an integrally formed structure.

[0068] In some examples, in addition to the upper expansion wing 1141 and the lower expansion wing 1142, the expansion wing 114 may also include a left expansion wing 114 and a right expansion wing 114. The left and right expansion wings 114 are located on the left and right sides of the upper expansion wing 1141 and the lower expansion wing 1142, respectively. The left expansion wing 114 and the right expansion wing 114 can open and close relative to each other in the horizontal direction. This embodiment does not limit this.

[0069] Reference Figure 2 or Figure 4 As shown, whether the image processing device 200 is used with an endoscope having a tube 112 or with an expander, the image processing device 200 can be detachably connected to the grip 120 to achieve a detachable connection with the operator 100.

[0070] The image processing device 200 may internally house components such as a lens, an image processor, and a motherboard (the imaging module, image processor, and motherboard are not shown in the figure). The image sensor is electrically connected to the motherboard, which can be electrically connected to an external device (such as a display). The image sensor converts digital signals captured by the camera at the distal end of the lens or lens tube 112 of the image processing device 200 into image signals. These image signals are transmitted to the motherboard so that the image of the target body part can be displayed on an external device.

[0071] It should be noted that by incorporating a lens into the image processing device 200, the image processing device 200 itself possesses a shooting function. When the image processing device 200 is paired with a manipulator 100 (e.g., an expander) that lacks a shooting function, it can capture images of target areas within the body. Furthermore, when the image processing device 200 is paired with a manipulator 100 equipped with a lens tube 112, the image sensor within the image processing device 200 can also acquire signals from a camera at the distal end of the lens tube 112 and transmit these image signals to an external device for display.

[0072] Thus, the image processing device 200 is more versatile and can be adapted to different types of endoscopes. Depending on the application scenario, different manipulators 100 can be used in conjunction with the image processing device 200, making the inspection device 1 more convenient and flexible to use.

[0073] Regarding the electrical connection between the image processing device 200 and external devices, such as Figure 2 or Figure 4 As shown, the image processing device 200 and the external device can be connected via a wired connection. The image processing device 200 can be provided with an interface 210, which enables the image processing device 200 to achieve an electrical connection with the external device. Of course, in some embodiments, the image processing device 200 and the external device can also communicate wirelessly. Based on this, by providing the interface 210 on the image processing device 200, the image processing device 200 and the external device can be connected wirelessly or via a wired connection, resulting in higher flexibility and reliability in signal transmission between the image processing device 200 and the external device.

[0074] The following description uses the image processing device 200 in conjunction with an endoscope having a tube 112 as an example to illustrate the structure of the examination device 1.

[0075] Reference Figure 2 or Figure 4 As shown, in this embodiment, the gripping portion 120 of the operator 100 has a receiving cavity 120a, which extends along the axial direction of the gripping portion 120. The image processing device 200 is installed in the receiving cavity 120a of the gripping portion 120. Thus, the gripping portion 120 encloses the image processing device 200, isolating the reusable image processing device 200 from the external environment. This ensures that the image processing device 200 remains hygienic and clean during use, effectively reducing the probability of contamination and improving the safety of the inspection device 1.

[0076] The bottom end of the grip portion 120 (the end of the grip portion 120 away from the operation portion 110) can be open, and the image processing device 200 can be inserted into the grip portion 120 from the opening of the grip portion 120. That is, the image processing device 200 can be inserted into the receiving cavity 120a of the grip portion 120 from the opening at the bottom end of the grip portion 120 along the axial direction of the grip portion 120.

[0077] To address this, the interface 210 on the image processing device 200 can be located at the bottom end of the image processing device 200. This exposes the interface 210 at the bottom of the grip portion 120, facilitating connection between the image processing device 200 and external devices. Furthermore, this avoids placing the interface 210 on the side wall of the image processing device 200, and consequently, avoids creating an opening in the side wall of the grip portion 120 to expose the image processing device 200, thus preventing liquid on the side wall of the grip portion 120 from entering the receiving cavity 120a and contaminating the image processing device 200.

[0078] In some embodiments, the image processing device 200 may be provided with only one interface 210, which may be located at the bottom of the image processing device 200. The interface 210 is used to enable the image processing device 200 to be electrically connected to an external device. Typically, the interface 210 is used to electrically connect the image processing device 200 to a display device so that the image acquired by the image processing device 200 can be displayed on the display device.

[0079] Figure 5 This is a bottom view structural diagram of an image processing apparatus provided in an embodiment of this application. (Refer to...) Figure 5 As shown, in other embodiments, the image processing device 200 may also be provided with two or more interfaces 210, each of which is used to connect to external devices. In this way, the image processing device 200 can connect to two or more external devices at the same time, making the image processing device 200 more functional and versatile, thereby improving the operational performance of the inspection device 1.

[0080] Taking an image processing device with two interfaces 210 as an example, the two interfaces 210 are a first interface 211 and a second interface 212, respectively. The first interface 211 is used to electrically connect to a first external device, and the second interface 212 is used to electrically connect to a second external device.

[0081] The first external device can be the aforementioned display device. In other words, the first interface 211 is used to electrically connect the image processing device 200 to the display device so as to display the image acquired by the image processing device 200 on the display device. The second external device can be, for example, some surgical instruments that require electrical control. In other words, the second interface 212 is used to electrically connect to the surgical instruments. In this way, the battery in the image processing device 200 can be used to power the surgical instruments, and the motherboard in the image processing device 200 can also control the surgical instruments, for example, it can control parameters such as the rotation speed of the surgical instruments.

[0082] All interfaces 210 on the image processing device 200, such as the first interface 211 and the second interface 212, can be located at the bottom of the image processing device 200, and the interfaces 210 are spaced apart to expose each interface 210 to the opening at the bottom of the grip portion 120, facilitating connection of each interface 210 to external devices. Furthermore, depending on the data transmission requirements between the image processing device 200 and different external devices, the types of different interfaces 210 can be the same or different; this embodiment does not impose any restrictions on this.

[0083] Continue to refer to Figure 2 or Figure 4 The figure shows the bottom opening of the grip 120, in which the bottom of the image processing device 200 is completely exposed within the opening of the bottom of the grip 120. At this time, the interface 210 at the bottom of the image processing device 200 is also exposed within the opening of the grip 120, allowing the image processing device 200 to be directly electrically connected to an external device.

[0084] In other embodiments, the inspection device 1 may also be provided with an end cap (not shown in the figure). The end cap, which can be opened and closed, is located at the bottom end of the grip portion 120. After the image processing device 200 is inserted into the receiving cavity 120a of the grip portion 120, the end cap encapsulates the image processing device 200 within the grip portion 120. The end cap can serve to fix and limit the image processing device 200. Alternatively, there may be no connection between the image processing device 200 and the grip portion 120, and the end cap can be used to completely limit the image processing device 200 within the receiving cavity 120a. Or, the image processing device 200 and the grip portion 120 may be connected together, and the end cap can be used for auxiliary limiting to prevent the image processing device 200 from falling out of the receiving cavity 120a.

[0085] At this time, an allowance opening can be provided on the end cover, which corresponds to the interface 210 at the bottom of the image processing device 200. The interface 210 of the image processing device 200 is exposed in the allowance opening of the end cover to facilitate the electrical connection between the image processing device 200 and external devices.

[0086] When the image processing device 200 has only one interface 210 at its bottom, only one clearance opening can be provided on the end cover. When the image processing device 200 has two or more interfaces 210 at its bottom, two or more clearance openings can be provided at the bottom of the image processing device 200, with each clearance opening corresponding to each interface 210, and each interface 210 exposed within the corresponding clearance opening.

[0087] Taking the image processing device 200 with a first interface 211 and a second interface 212 at the bottom as an example, a first clearance opening and a second clearance opening can be opened on the end cover. The first clearance opening and the second clearance opening correspond to the first interface 211 and the second interface 212 respectively. The first interface 211 is exposed in the first clearance opening, and the second interface 212 is exposed in the second clearance opening.

[0088] For example, the end cap can be connected to the bottom end of the grip 120. For instance, one side of the end cap is rotatably connected to the grip 120 via a pivot or hinge, and the other side of the end cap is snapped into the grip 120. Alternatively, the end cap can be fixed to the bottom end of the image processing device 200. Or, the end cap can be independent of the grip 120. For instance, the end cap can be screwed onto the grip 120 in a threaded connection.

[0089] Regarding the architecture of the grip 120, in some examples, the grip 120 can be a one-piece molded structure, which has good integrity and high reliability. In this case, the only option is to insert the image processing device 200 into the receiving cavity 120a axially from the opening at the bottom of the grip 120.

[0090] In other examples, the grip portion 120 may also be composed of two or more separate parts joined together. For example, the grip portion 120 may include two separate parts joined sequentially along the circumference. The parts may be fixedly connected together by snap-fit, adhesive, or mechanical connection. Alternatively, the adjacent sides of the two parts may be rotatably connected, while the other side may be snap-fitted. In this case, the grip portion 120 may be assembled first to form a complete grip portion 120, and the image processing device 200 may be inserted into the receiving cavity 120a through the opening at the bottom of the grip portion 120. Alternatively, the image processing device 200 may be placed into the grip portion 120 when the parts of the grip portion 120 are not fully assembled and the grip portion 120 is in an "open" state, and then the grip portion 120 may be assembled completely.

[0091] For the grip portion 120 which is assembled from separate parts, the section of the grip portion 120 near the bottom can be a single-piece structure, and the seam of the splicing part can be located on the side of the grip portion 120 facing away from the operation part 110, so as to prevent liquid (especially liquid flowing along the outer wall surface of the grip portion 120 facing the operation part 110) from entering the receiving cavity 120a through the seam of the grip portion 120, and to prevent liquid from contaminating the image processing device 200 in the receiving cavity 120a.

[0092] As for the outline shape of the grip portion 120, refer to Figure 2 or Figure 4 In one embodiment, the housing of the grip portion 120 may include a first wall portion 121 and a second wall portion 122. The first wall portion 121 forms a sidewall of the grip portion 120 facing away from the operating portion 110, and the second wall portion 122 is connected to the side of the first wall portion 121 facing the operating portion 110. The first wall portion 121 and the second wall portion 122 together form an accommodating cavity 120a. The curvature of the first wall portion 121 may be greater than 150°, in other words, the first wall portion 121 is flat. The cross-section of the second wall portion 122 may be similar to a "U" shape. The second wall portion 122 has a large curvature and occupies more planar space. The first wall portion 121 and the second wall portion 122 may have an arc transition.

[0093] This design provides several advantages. First, the cavity 120a formed by the first wall portion 121 and the second wall portion 122 has sufficient space to ensure that the image processing device 200 can be smoothly installed into the grip portion 120. Second, the flat first wall portion 121 facilitates the placement of the operating element 123, and the curved shape of the second wall portion 122 is ergonomic, making it easy to grip and improving the comfort of the grip portion 120. Furthermore, the different curvatures of the first wall portion 121 and the second wall portion 122 prevent the grip portion 120 from spinning in the operator's hand, thus preventing mistake-proofing.

[0094] Of course, in other examples, the outer contour of the grip portion 120 can be designed in other shapes. For example, the cross-section of the grip portion 120 can be circular, elliptical, hexagonal or octagonal, etc. This embodiment does not impose specific limitations.

[0095] Continue to refer to Figure 2 or Figure 4 As shown, a control panel 220 can also be provided on the side wall of the image processing device 200. The control panel 220 can have multiple buttons, each corresponding to a control component on a keypad (not shown) within the image processing device 200. The keypad can be electrically connected to the main board. By pressing the buttons to operate the corresponding control components, the human-computer interaction control function of the image processing device 200 can be realized. For example, each button can control functions such as image zooming, light source color switching, light source brightness adjustment, video freezing, and inputting and aspirating liquid (into the lens tube 112).

[0096] Corresponding to the control panel 220 on the side wall of the image processing device 200, an operating member 123 may be provided on the outer side wall of the grip portion 120. The operating member 123 may cover the control panel 220 of the image processing device 200, and the contour of the operating member 123 may match the contour of the control panel 220. By applying pressure to the corresponding area of ​​the operating member 123, the corresponding button on the control panel 220 is pressed.

[0097] For example, the operating part 123 can be made of soft materials such as silicone or rubber to make it easier to press down and increase the friction in the area where the operating part 123 is located, so as to ensure the accuracy of the operator's operation.

[0098] For ease of explanation, in this embodiment, the side surface of the grip 120 where the operating member 123 is provided is defined as the operating surface. The operating surface can be the side surface of the grip 120 facing away from the operating part 110. When operating the examination device 1, the operating part 110 of the manipulator 100 typically extends towards the target area inside the body, while the side of the grip 120 facing away from the operating part 110 faces the operator (e.g., a doctor). By using the side surface of the grip 120 facing away from the operating part 110 as the operating surface—in other words, by placing the operating member 123 on the side surface of the grip 120 facing away from the operating part 110—it is easier for the operator to observe and operate. Correspondingly, the control panel 220 on the image processing device 200 can be located on the side surface of the image processing device 200 facing away from the operating part 110.

[0099] In addition to providing a control panel 220 on the side of the image processing device 200 facing away from the operation unit 110, in some embodiments, a button (not shown in the figure) can also be provided on the outer side wall of the image processing device 200 facing the operation unit 110. Since it is on the side that is not easily observed from the operator's perspective, only one button can be provided on this side of the image processing device 200. This button is, for example, a switch that controls the image processing device 200 to be turned on and off. The part of the grip 120 corresponding to the button of the image processing device 200 can be provided with a clearance hole or covered with a soft rubber layer.

[0100] In this embodiment, the end of the grip portion 120 away from the operation portion 110 has a flared section 124, which is similar to a trumpet shape. In other words, the opening area of ​​the flared section 124 gradually increases along the direction close to the bottom end of the grip portion 120.

[0101] By providing a flared section 124 at the bottom of the gripping part 120, the opening area of ​​the gripping part 120 is increased, providing more assembly space for the image processing device 200 to be inserted into the receiving cavity 120a through the opening of the gripping part 120, reducing the assembly difficulty of the image processing device 200, and improving the assembly efficiency of the image processing device 200.

[0102] On the other hand, the flared section 124 can serve as a guide. For liquid flowing from the endoscope tube 112 or the operator's hand to the outer wall of the grip 120, the liquid flows along the outer wall of the grip 120 to the flared section 124 at the bottom of the grip 120. The outer wall of the flared section 124 can guide the liquid to the image processing device 200 away from the receiving cavity 120a, which can prevent the liquid from entering the receiving cavity 120a and adhering to the surface of the image processing device 200, thus preventing liquid from contaminating the image processing device 200. In particular, for liquid flowing out of the body, it can prevent cross-contamination of the image processing device 200, thereby improving the safety of using the examination device 1.

[0103] Additionally, refer to Figure 2 or Figure 4 As shown, in this embodiment, in addition to providing a flared section 124 at the bottom end of the gripping part 120, a protrusion 230 is also provided at the bottom end of the outer wall of the image processing device 200 (the end of the image processing device 200 away from the operation part 110), and the protrusion 230 protrudes to the periphery of the image processing device 200.

[0104] On the one hand, the protrusion 230 facilitates the operator's grip, enabling quick and smooth insertion and removal of the image processing device 200, thus achieving rapid assembly and disassembly of the image processing device 200. On the other hand, the protrusion 230 cooperates with the flared section 124 to limit the image processing device 200, accurately positioning its axial position, that is, the position where the image processing device 200 mates with the gripping part 120 in the axial direction, thereby improving the assembly accuracy of the inspection device 1.

[0105] Regarding the engagement between the flared section 124 of the grip portion 120 and the protrusion 230 of the image processing device 200, in some examples, the protrusion height of the protrusion 230 may be greater than the outward expansion (width of outward expansion) of the corresponding area of ​​the flared section 124, and the protrusion 230 may abut against the end of the flared section 124. In other words, the upper end of the protrusion 230 (the end of the protrusion 230 away from the bottom end of the image processing device 200) may abut against the bottom end surface of the grip portion 120. In other examples, the protrusion height of the protrusion 230 may be less than the widening of the corresponding area of ​​the flared section 124, and the protrusion 230 may extend into the flared section 124 a certain distance and abut against the inner wall surface of the flared section 124.

[0106] Continue to refer to Figure 2 or Figure 4 As shown, in one embodiment, the protrusion 230 at the bottom of the image processing device 200 can protrude on the side of the image processing device 200 facing away from the operation part 110. That is, the protrusion 230 corresponds to the side of the grip part 120 facing away from the operation part 110. As mentioned above, in use, the operation part 110 of the operator 100 extends into the target part inside the body, and the side of the grip part 120 facing away from the operation part 110 faces the operator. By providing the protrusion 230 on the side of the image processing device 200 facing away from the operation part 110, it is easier for the operator to observe the protrusion 230, which facilitates the smooth and quick assembly of the image processing device 200.

[0107] During surgery, fluid enters the target area inside the body through the endoscope tube 112 of the manipulator 100. Fluid within the body also flows along the endoscope tube 112 or the dilator towards the grip 120. Therefore, typically, more fluid adheres to the side of the grip 120 facing the manipulator 110. For this, refer to... Figure 6 As shown in the figure, Figure 1 In the side view of the inspection device, the outward expansion of the flared section 124 of the grip 120 facing the operation section 110 can be greater than the outward expansion of the flared section 124 facing away from the operation section 110. In this way, the flared section 124 of the grip 120 facing the operation section 110 can guide the liquid flowing along the outer wall of the grip 120 away from the grip 120, thereby preventing the liquid from entering the receiving cavity 120a and avoiding liquid contamination of the image processing device 200.

[0108] Figure 7 for Figure 1 An exploded view of the inspection device in the diagram. (Refer to...) Figure 7 As shown, in this embodiment, in addition to the flared section 124 at the bottom end of the gripping part 120, a guide groove 125 can also be provided on the outer wall of the gripping part 120. The guide groove 125 extends from the top end of the gripping part 120 (the end where the gripping part 120 is connected to the operating part 110) to the bottom end of the gripping part 120. For example, the guide groove 125 can extend along the axial direction of the gripping part 120. Liquid flowing along the outer wall surface of the operating part 110 to the outer wall surface of the gripping part 120 can enter the guide groove 125 and flow along the guide groove 125. The guide groove 125 can guide and restrict the liquid flow. In conjunction with the flared section 124 at the bottom end of the gripping part 120, liquid can be prevented from entering the receiving cavity 120a from the outer wall surface of the gripping part 120 (the bottom end of the gripping part 120 or the splice seam between the parts).

[0109] For example, the flow channel 125 can be an inwardly recessed groove on the outer wall of the grip portion 120, or the flow channel 125 can be formed by a flow guide strip protruding from the outer wall of the grip portion 120. By providing the flow channel 125 on the outer wall of the grip portion 120, an uneven surface is formed on the outer wall of the grip portion 120, which can increase the friction when the operator holds the grip and prevent the inspection device 1 from slipping.

[0110] Since the operating part 110 has a lot of liquid attached to it, and under the action of gravity, the liquid flows to the lower part of the operating part 110 and flows along the outer wall of the operating part 110 to the side of the grip part 120 facing the operating part 110, a lot of liquid accumulates on the outer wall of the grip part 120 facing the operating part 110. Therefore, the guide groove 125 can be set on the side of the grip part 120 facing the operating part 110. That is to say, the guide groove 125 can be located on the side of the grip part 120 away from the operating part 110.

[0111] In addition, continue to refer to Figure 7 As shown, the dashed box on the outer wall of the image processing device 200 indicates the location of the lens 240. A light-transmitting plate can be installed at this location on the housing of the image processing device 200 to allow light to pass through the plate and enter the lens 240. The lens 240 is typically located on the side of the image processing device 200 facing the operation section 110, and can be positioned at the top of the image processing device 200 near the operation section 110. This arrangement facilitates exposing the light-receiving surface of the lens 240 within the opening of the expansion wing 114 of the expander (see Figure 114). Figure 4 ( ), so that lens 240 can acquire images of the target area inside the body.

[0112] When the image processing device 200 is used with an endoscope having a tube 112, in some embodiments, an observation window 126 can be provided on the side wall of the grip 120 facing the operating part 110. The observation window 126 corresponds to the lens 240 of the image processing device 200. For example, the observation window 126 can be provided at the top of the grip 120 near the operating part 110, so that the lens 240 of the image processing device 200 is exposed inside the observation window 126. In this way, in addition to taking images of the target area inside the body through the tube 112, images of superficial tissues can also be taken using the lens 240 of the image processing device 200. Taking hysteroscopy as an example, the lens 240 of the image processing device 200 can take images of the area around the uterine cavity, helping doctors make a more comprehensive judgment and more accurately locate the position of the tube 112.

[0113] Regarding the connection between the image processing device 200 and the gripping part 120, a first connecting part (not shown in the figure) may be provided on the inner wall surface of the gripping part 120, and a second connecting part (not shown in the figure) may be provided on the outer wall surface of the image processing device 200. The positions of the first connecting part and the second connecting part correspond, and the image processing device 200 is fixed in the receiving cavity 120a of the gripping part 120 by the cooperation of the first connecting part and the second connecting part.

[0114] In one embodiment, the image processing device 200 and the gripping part 120 can be connected by a snap-fit ​​method. The first connecting part provided on the inner wall surface of the gripping part 120 can be the first snap-fit ​​part, and the second connecting part provided on the outer wall surface of the image processing device 200 can be the second snap-fit ​​part. The first snap-fit ​​part and the second snap-fit ​​part snap-fit ​​together to realize the connection between the image processing device 200 and the gripping part 120.

[0115] For example, one of the first and second latching portions can be a latching protrusion, and the other can be a latching groove. The latching protrusion engages with the latching groove to latch the image processing device 200 into the receiving cavity 120a of the gripping portion 120. For example, the inner wall surface of the gripping portion 120 is provided with a latching groove, and the outer wall surface of the image processing device 200 is provided with a latching protrusion.

[0116] The first latching portion can be located on the inner top wall of the grip portion 120 (the inner wall surface of the end of the grip portion 120 facing the operation portion 110), and correspondingly, the second latching portion can be located on the top surface of the image processing device 200 (the end surface of the image processing device 200 facing the operation portion 110). Alternatively, the first latching portion can also be located on the inner side wall of the grip portion 120, and correspondingly, the second latching portion can be located on the outer side wall of the image processing device 200.

[0117] Alternatively, the image processing device 200 can be inserted into the receiving cavity 120a by pressing and snapping. When inserting the image processing device 200, press the image processing device 200 inward, and the second snap-fit ​​part of the image processing device 200 snaps into the first snap-fit ​​part of the holding part 120, and the image processing device 200 is snapped into the receiving cavity 120a. When it is necessary to remove the image processing device 200, press the image processing device 200 again, and the second snap-fit ​​part of the image processing device 200 disengages from the first snap-fit ​​part of the holding part 120, and the image processing device 200 can be taken out from the receiving cavity 120a.

[0118] In another embodiment, the image processing device 200 and the gripping part 120 can be connected by magnetic attraction. The first connecting part provided on the inner wall of the gripping part 120 can be the first magnetic attraction part, and the second connecting part provided on the outer wall of the image processing device 200 can be the second magnetic attraction part. The first magnetic attraction part and the second magnetic attraction part are opposite to each other and attract each other to realize the connection between the image processing device 200 and the gripping part 120.

[0119] For example, the first magnetic attraction portion and the second magnetic attraction portion can be magnetic elements mounted on the outer surfaces of the grip portion 120 and the image processing device 200. The first magnetic attraction portion can be located on the inner top wall of the grip portion 120, and correspondingly, the second magnetic attraction portion can be located on the top surface of the image processing device 200 (the end face of the image processing device 200 facing the operation portion 110). Alternatively, the first magnetic attraction portion can also be located on the inner side wall of the grip portion 120, and correspondingly, the second magnetic attraction portion can be located on the outer side wall of the image processing device 200.

[0120] It is understandable that by using a snap-fit ​​or magnetic connection to connect the image processing device 200 and the gripping part 120, since the first snap-fit ​​part (second snap-fit ​​part) or the first magnetic part (second magnetic part) has a fixed position on the gripping part 120 (image processing device 200), the connection between the image processing device 200 and the gripping part 120 can play a positioning role and ensure the positional accuracy of the image processing device 200.

[0121] When the receiving cavity 120a of the gripping part 120 is a cylindrical cavity and the image processing device 200 is a cylindrical structure, the image processing device 200 and the gripping part 120 can also be connected by a threaded connection. The first connecting part provided on the inner wall surface of the gripping part 120 can be an internal thread, and the second connecting part provided on the outer wall surface of the image processing device 200 can be an external thread. The internal thread and the external thread match each other to realize the connection between the image processing device 200 and the gripping part 120.

[0122] For example, the internal thread on the grip 120 can be provided near the top of the grip 120, so that the internal thread can avoid the area on the grip 120 where the operating member 123 is provided; correspondingly, the external thread on the image processing device 200 can also be provided near the top of the image processing device 200, so that the external thread can avoid the area on the image processing device 200 where the control panel 220 is provided.

[0123] Figure 8 for Figure 1 A structural diagram of the operating handle of the inspection device in one view; Figure 9 for Figure 1 A schematic diagram of the image processing device in the inspection apparatus.

[0124] In the case where the image processing device 200 is paired with an endoscope having a tube 112, since the camera and light source, etc., mounted at the distal end of the tube 112 need to be electrically connected to the mainboard inside the image processing device 200, therefore, referring to... Figure 8 As shown, a first electrical contact 127 may be provided on the inner wall surface of the gripping part 120, referring to... Figure 9 As shown, a second electrical contact 250 may be provided on the outer wall of the image processing device 200. The first electrical contact 127 and the second electrical contact 250 are in contact with each other. The first electrical contact 127 can be electrically connected to the device at the far end of the lens tube 112, and the second electrical contact 250 can be electrically connected to the main board inside the image processing device 200, thereby realizing signal transmission between the device at the far end of the lens tube 112 and the main board inside the image processing device 200.

[0125] like Figure 8 and Figure 9 As shown, in some embodiments, the first electrical contact 127 may be provided on the inner top wall of the grip portion 120, and correspondingly, the second electrical contact 250 may be provided on the top surface of the image processing device 200 (the end surface of the image processing device 200 facing the operation portion 110). This method can be applied to the first electrical contact 127 and the second electrical contact 250 being connected along the axial direction of the grip portion 120, so that pressure is generated between the first electrical contact 127 and the second electrical contact 250 in the axial direction of the grip portion 120, ensuring reliable contact between the first electrical contact 127 and the second electrical contact 250.

[0126] The image processing device 200 can be inserted into the receiving cavity 120a by moving along the axial direction of the holding part 120, which is adapted to the first electrical contact 127 and the second electrical contact 250. In this case, the image processing device 200 and the holding part 120 can be connected by snap-fit ​​or magnetic attraction. In other words, the first connecting part provided on the inner wall of the holding part 120 can be a first snap-fit ​​part or a first magnetic attraction part, and the second connecting part provided on the outer wall of the image processing device 200 can be a second snap-fit ​​part or a second magnetic attraction part.

[0127] Of course, provided that the first electrical contact 127 on the inner top wall of the grip 120 and the second electrical contact 250 on the top surface of the image processing device 200 are accurately aligned, when the grip 120 has a cylindrical cavity 120a and the image processing device 200 is cylindrical, the grip 120 and the image processing device 200 can also be connected by a screw fit. In other words, the first connecting part on the grip 120 can be an internal thread provided on its inner wall surface, and the second connecting part on the image processing device 200 can be an external thread provided on its outer wall surface.

[0128] In cases where the grip portion 120 has a cylindrical cavity 120a and the image processing device 200 is cylindrical, and when the grip portion 120 and the image processing device 200 are connected by a screw fit, in order to ensure the reliability of the contact between the first electrical contact portion 127 and the second electrical contact portion 250, in some embodiments, the first electrical contact portion 127 can be disposed on the inner sidewall of the grip portion 120 (circumferential direction), and correspondingly, the second electrical contact portion 250 can be disposed on the inner sidewall of the image processing device 200 (circumferential direction). On the outer side wall, the first electrical contact 127 and the second electrical contact 250 can be in the same horizontal plane. As the image processing device 200 is screwed into the grip 120, the first electrical contact 127 and the second electrical contact 250 are joined together in the circumferential direction of the grip 120. Pressure is generated between the first electrical contact 127 and the second electrical contact 250 in the circumferential direction of the grip 120 (e.g., in the tangential direction of the cross section of the grip 120) to ensure reliable contact between the first electrical contact 127 and the second electrical contact 250.

[0129] Furthermore, when the first electrical contact 127 is disposed on the inner side wall of the grip 120 and the second electrical contact 250 is disposed on the outer side wall of the image processing device 200, when the image processing device 200 rotates until the second electrical contact 250 abuts against the first electrical contact 127 inside the grip 120, the image processing device 200 is restricted to its current position in the circumferential direction of the grip 120 and cannot continue to rotate. In this way, it also serves to position the image processing device 200 in the circumferential direction of the grip 120.

[0130] For example, one of the first electrical contact portion 127 and the second electrical contact portion 250 may include a plurality of conductive posts, and the other may include a plurality of conductive sheets, with the conductive posts abutting against the conductive sheets to achieve electrical contact between the two.

[0131] In one example, the first electrical contact 127 is disposed on the inner top wall of the grip portion 120, and the second electrical contact 250 is disposed on the top surface of the image processing device 200. The first electrical contact 127 on the inner top wall of the grip portion 120 includes a conductive post (see...). Figure 8 The second electrical contact 250 on the top surface of the image processing device 200 includes a conductive sheet (see image processing device 200). Figure 9 This allows the conductive post to pass through the operating part 110 and extend onto the top surface of the holding part 120. The conductive post can be electrically connected to the device at the far end of the mirror tube 112 via a cable provided inside the operating part 110.

[0132] In the case where the first electrical contact 127 is located on the inner side wall of the grip 120 and the second electrical contact 250 is located on the outer side wall of the image processing device 200, the first electrical contact 127 may include a conductive post and the second electrical contact 250 may include a conductive sheet, or the first electrical contact 127 may include a conductive sheet and the second electrical contact 250 may include a conductive post. In this case, the cable provided in the operation part 110 can be led out to the receiving cavity 120a of the grip 120 and connected to the first electrical contact 127.

[0133] Figure 10 for Figure 1 A structural diagram of the operating handle of the inspection device from another perspective. (Refer to...) Figure 10 As shown, in some embodiments, a support portion 128 may also be provided on the inner sidewall of the grip portion 120. The support portion 128 may protrude on the inner sidewall of the grip portion 120. The support portion 128 is used to support the image processing device 200. That is, the outer sidewall of the image processing device 200 may abut against the support portion 128.

[0134] In this way, the image processing device 200 can be positioned using the support part 128 to prevent the image processing device 200 from shaking in the receiving cavity 120a, ensuring that the image processing device 200 is securely fixed, and also helping to align the second electrical contact part 250 on the image processing device 200 with the first electrical contact part 127 in the holding part 120.

[0135] As an example, the support portion 128 may include support bars 128a disposed on the inner sidewall of the grip portion 120. The support portion 128 may include at least two support bars 128a, which are spaced apart. For example, the support portion 128 may include two, three, four or even more support bars 128a disposed at intervals. The outer sidewall of the image processing device 200 abuts against the support bars 128a to position the image processing device 200.

[0136] The support bar 128a extends along the length of the grip portion 120. While supporting the image processing device 200, the support bar 128a also guides the movement of the image processing device 200. A guide groove (not shown) can be provided on the outer wall of the image processing device 200. This guide groove can be, for example, a recessed groove on the outer wall of the image processing device 200 or a groove formed by protruding guide bars on the outer wall of the image processing device 200. The guide groove extends along the length of the image processing device 200. When assembling the image processing device 200, the support bar 128a on the inner wall of the grip portion 120 extends into the guide groove on the outer wall of the image processing device 200, and slides along the guide groove to guide the image processing device 200, ensuring accurate alignment of the image processing device 200.

[0137] As previously mentioned, in some embodiments, especially for endoscopes equipped with endoscope tube 112, the manipulator 100 also includes a tubing assembly 130. (Continuing with...) Figure 10 The tubing assembly 130 may include an inlet pipe 131 and an outlet pipe 132. Both the inlet pipe 131 and the outlet pipe 132 extend into the operating part 110 of the manipulator 100 and communicate with the endoscope tube 112. The inlet pipe 131 is used to deliver liquid into the endoscope tube 112 so that the liquid enters the target part of the body through the endoscope tube 112. The outlet pipe 132 is used to discharge the liquid in the endoscope tube 112 so that the liquid flowing back into the endoscope tube 112 from the body is discharged out of the examination device 1 through the outlet pipe 132.

[0138] Taking the application of the examination device 1 to hysteroscopy as an example, the inlet tube 131 can be used to deliver distending fluid into the endoscope tube 112. The distending fluid is sprayed from the distal end of the endoscope tube 112 into the uterine cavity. The distending fluid in the uterine cavity can also flow back into the endoscope tube 112 and be discharged through the outlet tube 132 of the distending fluid that flows back into the endoscope tube 112.

[0139] Reference Figure 10 As shown, in this embodiment, the inlet pipe 131 and outlet pipe 132 within the operating part 110 can extend into the gripping part 120, and can extend along the inner wall of the gripping part 120 and protrude from the opening at the bottom end of the gripping part 120. With this configuration, the inlet pipe 131 and outlet pipe 132 are completely sealed within the housing of the operator 100, allowing the operator 100 to limit and protect the inlet pipe 131 and outlet pipe 132, resulting in better stability. Furthermore, it avoids the inlet pipe 131 and outlet pipe 132 being exposed outside the gripping part 120, preventing obstruction of the operator's grip and preventing leakage to the outer wall of the gripping part 120, thus avoiding contamination of the operator 100.

[0140] Of course, in other embodiments, the inlet pipe 131 and the outlet pipe 132 can also extend directly from the operating part 110 to the outside of the operator 100. In this case, a recess can be provided on the side wall of the grip part 120 facing the operating part 110, and the inlet pipe 131 and the outlet pipe 132 can be accommodated in the recess to limit the inlet pipe 131 and the outlet pipe 132 and avoid obstructing the operator's grip.

[0141] Taking the extension of the inlet pipe 131 and the outlet pipe 132 along the inner wall of the grip portion 120 as an example, the inlet pipe 131 and the outlet pipe 132 can be located on the inner wall of the grip portion 120 near the operation portion 110. In other words, the inlet pipe 131 and the outlet pipe 132 extend along the inner wall of the grip portion 120 near the operation portion 110.

[0142] On the one hand, the inlet pipe 131 and the outlet pipe 132 both extend along the same side surface within the grip portion 120. The extension paths of the inlet pipe 131 and the outlet pipe 132 are short and can extend in a straight line, which can ensure smooth flow of liquid within the inlet pipe 131 and the outlet pipe 132. The inlet pipe 131 and the outlet pipe 132 occupy a small overall space, which helps to miniaturize the grip portion 120.

[0143] On the other hand, when in use, the side of the grip 120 away from the operation part 110 usually faces the sky, and the side of the grip 120 facing the operation part 110 usually faces the ground. By setting the inlet pipe 131 and the outlet pipe 132 on the inner side wall of the grip 120 near the operation part 110, the side wall of the grip 120 can support the inlet pipe 131 and the outlet pipe 132, thereby improving the reliability of the inlet pipe 131 and the outlet pipe 132.

[0144] For example, the inlet pipe 131 and the outlet pipe 132 can be integrally formed on the inner wall of the grip portion 120. In other words, the inlet pipe 131 and the outlet pipe 132 can be formed on the inner wall of the grip portion 120. In this way, the inlet pipe 131 and the outlet pipe 132 have good integrity with the grip portion 120, the pipe segments of the inlet pipe 131 and the outlet pipe 132 in the grip portion 120 are fixed in position, which is convenient for docking with the pipe segments in the operating portion 110. Moreover, the pipe segments of the inlet pipe 131 and the outlet pipe 132 in the grip portion 120 are all integral structures, which provides better sealing.

[0145] Additionally, refer to Figure 10As shown, when the inner wall of the grip 120 is provided with a support 128, the support 128 can also be used to separate separate spaces for the inlet pipe 131 and the outlet pipe 132. At this time, the support 128 can be provided on the periphery of the inlet pipe 131 and the outlet pipe 132, and the protrusion height of the support 128 is greater than the protrusion height of the inlet pipe 131 and the outlet pipe 132. When the image processing device 200 abuts against the support 128, there is a gap between the outer wall of the image processing device 200 and the inlet pipe 131 and the outlet pipe 132, which can prevent the image processing device 200 from interfering with the inlet pipe 131 and the outlet pipe 132 and avoid damage to the inlet pipe 131 and the outlet pipe 132.

[0146] In the figure, taking the support part 128 as the support bar 128a as an example, a support bar 128a can be set between the liquid inlet pipe 131 and the liquid outlet pipe 132, and a support bar 128a can be set on each of the opposite sides of the liquid inlet pipe 131 and the liquid outlet pipe 132. Alternatively, a support bar 128a can be set only on each of the opposite sides of the liquid inlet pipe 131 and the liquid outlet pipe 132.
