[0046] In clinical medicine, endoscopes are often used to inspect the target position of the internal cavity of the human body. Due to the shortcomings of traditional endoscopes, such as high cost, complex structure, cumbersome operation, and easy infection, the development and use of disposable endoscopes have gradually emerged.

[0047] However, the disposable endoscopes in the related art are unhygienic and prone to cross infection due to the operator's touching during use, liquid leakage and incomplete disinfection after surgery.

[0048] In view of this, an embodiment of the present application provides an inspection device, which includes a detachably connected operator and an image processing device. By providing a receiving cavity on the gripping portion of the operator, the image processing device is installed in the receiving cavity, and the gripping portion wraps the image processing device to isolate the image processing device from the external environment, thereby ensuring that the image processing device is hygienic and clean. In addition, by providing a flared section at one end of the gripping portion away from the operator, the diversion effect of the flared section can prevent the liquid on the outer wall of the gripping portion from contaminating the image processing device, thereby avoiding cross infection and improving the safety of the inspection device. In addition, by providing a protruding portion on the outer wall of the image processing device away from the operator, the protruding portion and the flared section are used to limit the image processing device, thereby ensuring the position accuracy of the image processing device and improving the assembly accuracy of the inspection device.

[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] Figure 1 A three-dimensional structural diagram of an inspection device provided in an embodiment of the present application; Figure 2 for Figure 1 An exploded structural diagram of an inspection device from one perspective; Figure 3 A three-dimensional structural diagram of another inspection device provided in an embodiment of the present application; Figure 4 for Figure 3 Exploded structure diagram of the inspection device in .

[0051] Reference Figures 1 to 4 As shown, the embodiment of the present application 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 name implies, the disposable part is a non-reusable part, and the reusable part is a repeatedly used part.

[0052] Among them, as a disposable part, the operator 100 may include a part that enters the human body and contacts (or may contact) the human epidermis and tissue; as a reusable part, the image processing device 200 may include a part that does not need to enter the human body and can be reused.

[0053] The inspection device 1 is assembled by setting an operator 100 and an image processing device 200. 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 causing cross infection is reduced, which can improve the safety of using the inspection device 1. On the other hand, by reusing the image processing device 200, material waste is avoided and the use cost of the inspection device 1 is reduced.

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

[0055] As a disposable part, the operator 100 may include an operating portion 110 and a gripping portion 120, wherein the gripping portion 120 is connected to one axial end of the operating portion 110. When in use, the operator 100 is extended toward the human body, and the operator 100 at least partially extends into the target part of the body, and the gripping portion 120 is used for the operator to hold it to realize the control of the inspection device 1.

[0056] Among them, the holding portion 120 is inclined to the operating portion 110. In other words, there is an angle between the axial direction of the holding portion 120 and the axial direction of the operating portion 110 to meet the angle requirement of the operation. On the basis of ensuring that the operating portion 110 can enter or reach the target part of the human body, the comfort of the operator's holding is guaranteed, and the space requirement of the operator for operating the inspection device 1 can also be met.

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

[0058] In other examples, the holding portion 120 and the operating portion 110 can be rotatably connected, and the holding portion 120 and the operating portion 110 can be connected together by a structure such as a rotating shaft or a hinge. The angle between the holding portion 120 and the operating portion 110 can be adjusted according to operational requirements. For example, the angle between the holding portion 120 and the operating portion 110 can be adjusted between 90° and 150°, and a damping structure can be provided to stabilize the holding portion 120 and the operating portion 110 in a desired tilted state.

[0059] Among them, refer to Figure 1 or Figure 2 As shown, in some embodiments, the operator 100 used with the inspection device 1 can be an endoscope having a slender tube extending into the body. For example, the operator 100 used with the inspection device 1 can be an endoscope such as a neuroscope, a urethral cystoscope, an electroresectoscope, a laparoscope, an arthroscope, a sinusoscope, or a laryngoscope.

[0060] At this time, the operating part 110 of the operator 100 may include a main body 111 and a mirror tube 112, the mirror tube 112 is installed on the side of the main body 111 away from the gripping part 120, and the mirror tube 112 is used to extend into the target part of the body. In addition, the operating part 110 may also include a knob 113, which is rotatably installed at one axial end of the operating part 110, the main body 111, the knob 113 and the gripping part 120 together constitute an operating handle, and the mirror tube 112 and the operating handle together constitute the operator 100.

[0061] The distal end of the mirror tube 112 is usually equipped with components such as a camera (not shown in the figure), a light source (not shown in the figure), etc. During surgery, the mirror tube 112 is extended into the body, the target part is illuminated by the light source, and the image of the target part is observed by the camera. A pipeline assembly (not shown in the figure) and a cable (not shown in the figure) are installed in the operating handle. The pipeline assembly is used to realize the inflow and outflow of liquid in the mirror tube 112 to meet the needs during the operation. The cable is used to electrically connect to the camera, light source, etc. at the distal end of the mirror tube 112 to achieve the purpose of the inspection device 1 to observe local fine tissues in the body.

[0062] The knob 113 is used to drive the mirror tube 112 to rotate, and then to move the camera installed at the far end of the mirror tube 112, so as to observe different areas of the target part in the body. The knob 113 can be installed at one end of the main body 111 facing the grip 120 (as shown in the figure), and the knob 113 can drive the mirror tube 112 to rotate through the components installed in the main body 111; or the knob 113 can also be installed at one end of the main body 111 away from the grip 120, and the knob 113 is sleeved on the mirror tube 112, and the knob 113 directly drives the mirror tube 112 to rotate.

[0063] For example, the main body 111 and the gripping portion 120 may be fixedly connected, or the main body 111 and the gripping portion 120 may be rotatably connected. Figure 2 As shown in the figure, the shell of the main body 111 may include 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 in the main body 111; wherein the lower shell 1112 and the holding portion 120 may be fixedly connected by bonding, welding or mechanical connection, or the lower shell 1112 and the holding portion 120 may be an integrally formed structure.

[0064] Since the mirror tube 112 needs to enter the body, the operating handle needs to be held by the operator and may also contact the human epidermis or internal tissues. In addition, the liquid entering and leaving the body passes through the liquid control components installed in the operating handle, and the electric control components installed in the operating handle need to be connected to the far end of the mirror tube 112. Therefore, in this embodiment, the mirror tube 112 and the operating handle are used as disposable parts of the inspection device 1, which can reduce or even avoid the risk of contamination or cross infection of the mirror tube 112 and the operating handle.

[0065] Reference Figure 3 or Figure 4 As shown, in other embodiments, the manipulator 100 used with the inspection device 1 can be a dilator. In this case, the image processing device 200 serves as an endoscope, for example, the image processing device 200 can serve as a colposcope or a nasal cavity endoscope. In this case, the operating portion 110 of the manipulator 100 can include duckbill-shaped dilating wings 114 that cooperate with each other. The dilating wings 114 are connected to the gripping portion 120. The dilating wings 114 and the gripping portion 120 together constitute the manipulator 100, that is, the dilator.

[0066] The expansion wings 114 installed on the gripping portion 120 can be relatively opened and closed, and the expansion wings 114 are used to extend into the vagina or nasal cavity and other parts, and to open the corresponding parts. As shown in the figure, the expansion wings 114 may include an upper expansion wing 1141 and a lower expansion wing 1142, and the lower expansion wing 1142 is connected to the top of the gripping 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 be relatively opened and closed in the vertical direction.

[0067] For example, the lower expansion wing 1142 and the grip portion 120 may be fixedly connected, or the lower expansion wing 1142 and the grip portion 120 may be rotatably connected. Figure 4 As shown, the lower expansion wing 1142 can be fixedly connected to the gripping portion 120 by bonding, welding or mechanical connection, or the lower expansion wing 1142 and the gripping portion 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 respectively located on the left and right sides of the upper expansion wing 1141 and the lower expansion wing 1142. The left expansion wing 114 and the right expansion wing 114 can be relatively opened and closed in the horizontal direction, which is not limited in this embodiment.

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

[0070] Among them, the image processing device 200 may be installed with components such as a lens, an image processor, and a mainboard (the imaging module, the image processor, the mainboard, and the like are not shown in the figure), the image sensor is electrically connected to the mainboard, and the mainboard may be electrically connected to an external device (such as a display). Among them, the image sensor is used to convert the digital signal collected by the lens of the image processing device 200 or the camera at the far end of the mirror tube 112 into an image signal, and the image signal is transmitted to the mainboard so that the image of the target part in the body can be displayed on the external device.

[0071] It should be noted that by providing a lens in the image processing device 200, the image processing device 200 itself has a shooting function. When the image processing device 200 is used with an operator 100 (such as a dilator) that does not have a shooting function, the image of the target part in the body can be captured by the image processing device 200. In addition, when the image processing device 200 is used with an operator 100 having a mirror tube 112, the image sensor in the image processing device 200 can also obtain the signal of the camera at the far end of the mirror tube 112, and transmit the image signal to an external device for display.

[0072] In this way, the image processing device 200 is more versatile and can be adapted to different types of endoscopes. Depending on the application scenario, different operators 100 can be replaced for use with the image processing device 200, making the inspection device 1 more convenient and flexible to use.

[0073] As for the electrical connection between the image processing apparatus 200 and external devices, Figure 2 or Figure 4 As shown, the image processing apparatus 200 and the external device may be connected by wire, and the image processing apparatus 200 may be provided with an interface 210, and the image processing apparatus 200 uses the interface 210 to realize electrical connection with the external device. Of course, in some embodiments, the image processing apparatus 200 and the external device may also communicate wirelessly, and on this basis, by providing the interface 210 on the image processing apparatus 200, the image processing apparatus 200 and the external device may be connected wirelessly or by wire, and the flexibility and reliability of signal transmission between the image processing apparatus 200 and the external device are higher.

[0074] The structure of the inspection device 1 is described below by taking the use of the image processing device 200 in combination with an endoscope having a scope tube 112 as an example.

[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, and the image processing device 200 is installed in the receiving cavity 120a of the gripping portion 120. In this way, the gripping portion 120 wraps the image processing device 200 therein, isolating the reusable image processing device 200 from the external environment, and the image processing device 200 can always be kept hygienic and clean during use, which can effectively reduce the probability of the image processing device 200 being contaminated, and can improve the safety of the inspection device 1.

[0076] Among them, the bottom end of the holding portion 120 (the end of the holding portion 120 away from the operating portion 110) can be open, and the image processing device 200 can be inserted into the holding portion 120 from the opening of the holding portion 120, that is, the image processing device 200 can be inserted into the accommodating cavity 120a of the holding portion 120 along the axial direction of the holding portion 120 and from the opening at the bottom end of the holding portion 120.

[0077] In this regard, the interface 210 on the image processing device 200 can be set at the bottom of the image processing device 200, so that the interface 210 at the bottom of the image processing device 200 can be exposed to the opening at the bottom of the grip 120, which is convenient for the image processing device 200 to be connected to an external device. In addition, it is avoided that the interface 210 on the image processing device 200 is opened on the side wall of the image processing device 200, and accordingly, it is also avoided that an opening is opened on the side wall of the grip 120 to expose the opening of the image processing device 200, so as to avoid the liquid on the side wall of the grip 120 from entering the accommodating cavity 120a through the opening, thereby preventing the image processing device 200 from being contaminated.

[0078] In some embodiments, only one interface 210 may be provided on the image processing device 200, and the interface 210 may be provided at the bottom of the image processing device 200. The interface 210 is used to electrically connect the image processing device 200 to an external device. Typically, the interface 210 is used to electrically connect the image processing device 200 to a display device so as to display the image acquired by the image processing device 200 on the display device.

[0079] Figure 5 This is a bottom view of the structure of an image processing device provided in an embodiment of the present application. Figure 5 As shown, in other embodiments, more than two interfaces 210 may be provided on the image processing device 200, and each interface 210 is used to connect to an external device. In this way, the image processing device 200 can be connected to more than two external devices at the same time, so that the image processing device 200 has richer functions and wider applications, thereby improving the control performance of the inspection device 1.

[0080] For example, the image processing apparatus is provided with two interfaces 210 , the two interfaces 210 are respectively a first interface 211 and a second interface 212 , the first interface 211 is used for electrically connecting to a first external device, and the second interface 212 is used for electrically connecting to a second external device.

[0081] Among them, 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, for example, be some surgical instruments that require electrical control. In other words, the second interface 212 is used to electrically connect to the surgical instrument. In this way, the battery in the image processing device 200 can be used to power the surgical instrument, and the surgical instrument can also be controlled through the mainboard in the image processing device 200. For example, parameters such as the rotation speed of the surgical instrument can be controlled.

[0082] All interfaces 210 on the image processing device 200, such as the first interface 211 and the second interface 212, can be arranged at the bottom of the image processing device 200, and the interfaces 210 are arranged at intervals, so that the interfaces 210 are exposed at the opening at the bottom of the grip 120, so as to facilitate the connection of the interfaces 210 with external devices. In addition, according to the data transmission method requirements between the image processing device 200 and different external devices, the types of different interfaces 210 can be the same or different, and this embodiment does not limit this.

[0083] Continue to refer to Figure 2 or Figure 4 The figure shows that the bottom end of the holding portion 120 is open and the bottom end of the image processing device 200 is completely exposed in the opening at the bottom end of the holding portion 120. At this time, the interface 210 at the bottom end of the image processing device 200 is also exposed in the opening of the holding portion 120, and the image processing device 200 can be directly electrically connected to an external device.

[0084] In other embodiments, the inspection device 1 may also be provided with an end cover (not shown in the figure), and the end cover is an openable cover provided at the bottom end of the gripping portion 120. After the image processing device 200 is loaded into the accommodating cavity 120a of the gripping portion 120, the end cover encapsulates the image processing device 200 in the gripping portion 120. The end cover may play a role in fixing and limiting the image processing device 200. There may be no connection between the image processing device 200 and the gripping portion 120, and the image processing device 200 may be completely limited in the accommodating cavity 120a by the end cover; or the image processing device 200 and the gripping portion 120 may be connected together, and on this basis, the end cover is used for auxiliary limiting to prevent the image processing device 200 from escaping from the accommodating cavity 120a.

[0085] At this time, a clearance opening may be opened 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 clearance opening of the end cover to facilitate electrical connection between the image processing device 200 and external equipment.

[0086] When only one interface 210 is provided at the bottom of the image processing device 200, only one avoidance opening may be provided on the end cover. When more than two interfaces 210 are provided at the bottom of the image processing device 200, more than two avoidance openings may be provided at the bottom of the image processing device 200, each avoidance opening corresponds to each interface 210, and each interface 210 is exposed in the corresponding avoidance opening.

[0087] Taking the image processing device 200 having a first interface 211 and a second interface 212 at the bottom as an example, a first avoidance opening and a second avoidance opening may be opened on the end cover, the first avoidance opening and the second avoidance opening respectively corresponding to the first interface 211 and the second interface 212, the first interface 211 is exposed in the first avoidance opening, and the second interface 212 is exposed in the second avoidance opening.

[0088] Exemplarily, the end cap may be connected to the bottom end of the holding portion 120, for example, one side of the end cap is rotatably connected to the holding portion 120 via a rotating shaft or a hinge, and the other side of the end cap is snap-fitted to the holding portion 120; alternatively, the end cap may be fixed to the bottom end of the image processing device 200; alternatively, the end cap may be independent of the holding portion 120, for example, the end cap may be screwed onto the holding portion 120 in a threaded manner.

[0089] As for the structure of the grip portion 120, in some examples, the grip portion 120 may be an integrally formed structure, and the grip portion 120 has good integrity and high reliability. In this case, the image processing device 200 can only be inserted into the accommodating cavity 120a from the opening at the bottom of the grip portion 120 along the axial direction.

[0090] In other examples, the gripping portion 120 may also be formed by splicing more than two parts. For example, the gripping portion 120 includes two parts spliced ​​in sequence along the circumferential direction. The parts may be fixedly connected together by snapping, bonding or mechanical connection, or the adjacent sides of the two parts are connected by rotation and the other sides are snapped. In this case, the gripping portion 120 may be spliced ​​to form a complete gripping portion 120 first, and the image processing device 200 may be inserted into the accommodating cavity 120a from the opening at the bottom of the gripping portion 120; or, when the parts of the gripping portion 120 are not fully spliced ​​and the gripping portion 120 is in an "open" state, the image processing device 200 may be placed in the gripping portion 120, and then the gripping portion 120 may be spliced ​​to be complete.

[0091] For the holding portion 120 formed by splicing separate parts, a section of the holding portion 120 near the bottom can be an integral structure, and the splicing gap of the splicing part can be located on the side of the holding portion 120 facing away from the operating portion 110, so as to prevent liquid (especially liquid flowing along the outer wall surface of the holding portion 120 facing the operating portion 110) from entering the accommodating cavity 120a through the splicing gap of the holding portion 120, thereby preventing the liquid from contaminating the image processing device 200 in the accommodating cavity 120a.

[0092] As for the contour shape of the grip portion 120, refer to Figure 2 or Figure 4 As an 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 constitutes a side wall of the grip portion 120 facing away from the operating portion 110. 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 enclose a receiving 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, and 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 plane space. The first wall portion 121 and the second wall portion 122 may transition in an arc shape.

[0093] With such arrangement, on the one hand, the accommodation cavity 120a formed by the first wall portion 121 and the second wall portion 122 has enough space to ensure that the image processing device 200 can be smoothly loaded into the grip portion 120; on the other hand, the flat first wall portion 121 is convenient for arranging the operating member 123, and the curved surface shape of the second wall portion 122 conforms to ergonomics, is convenient for gripping, and can improve the comfort of the grip portion 120. In addition, the first wall portion 121 and the second wall portion 122 have different curvatures, which can prevent the grip portion 120 from spinning in the operator's hand, and is conducive to preventing foolishness.

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

[0095] Continue to refer to Figure 2 or Figure 4 As shown, a control panel 220 may be provided on the side wall of the image processing device 200, and a plurality of buttons may be provided on the control panel 220, each of which may correspond to each control element on a keypad (not shown) provided in the image processing device 200, and the keypad may be electrically connected to the main board. By pressing the button to control the corresponding control element, the human-computer interaction control function of the image processing device 200 is realized, for example, each button may control image zooming, light source color switching, light source brightness adjustment, video freezing, liquid input (into the mirror tube 112) and liquid aspiration, and other functions.

[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, and 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 on the corresponding area of ​​the operating member 123, the corresponding button on the control panel 220 is pressed.

[0097] Exemplarily, the operating member 123 may be made of soft materials such as silicone, rubber, etc., so that the operating member 123 is easier to be pressed down and the friction force in the area where the operating member 123 is located is increased to ensure the accuracy of the operator's operation.

[0098] For ease of explanation, in this embodiment, the side surface of the gripping portion 120 on which the operating element 123 is provided is defined as the operating surface, wherein the operating surface may be the side surface of the gripping portion 120 facing away from the operating portion 110. When operating the inspection device 1, the operating portion 110 of the operator 100 is usually extended toward the target part in the body, and the side of the gripping portion 120 facing away from the operating portion 110 faces the operator (e.g., a doctor). By using the side surface of the gripping portion 120 facing away from the operating portion 110 as the operating surface, in other words, the operating element 123 is provided on the side surface of the gripping portion 120 facing away from the operating portion 110, it is convenient for the operator to observe and operate. Accordingly, the control panel 220 on the image processing device 200 may be located on the side surface of the image processing device 200 facing away from the operating portion 110.

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

[0100] In this embodiment, the end of the grip portion 120 away from the operating portion 110 has a flared section 124 , which is shaped like a trumpet. In other words, the opening area of ​​the flared section 124 gradually increases along the direction approaching the bottom end of the grip portion 120 .

[0101] By providing a flared section 124 at the bottom end of the holding portion 120, on the one hand, the opening area of ​​the opening of the holding portion 120 is increased, which provides more assembly space for the image processing device 200 to be inserted into the accommodating cavity 120a from the opening of the holding portion 120, reduces the assembly difficulty of the image processing device 200, and improves the assembly efficiency of the image processing device 200.

[0102] On the other hand, the flared section 124 can play a diversion role. For the liquid flowing from the mirror tube 112 or the operator's hand to the outer wall of the holding portion 120, the liquid flows along the outer wall of the holding portion 120 to the flared section 124 at the bottom of the holding portion 120. The outer wall of the flared section 124 can divert the liquid to the image processing device 200 away from the accommodating cavity 120a, thereby preventing the liquid from entering the accommodating cavity 120a and adhering to the surface of the image processing device 200, thereby preventing the liquid from contaminating the image processing device 200, and especially for the liquid flowing out of the body, cross infection to the image processing device 200 can be avoided, thereby improving the safety of use of the inspection device 1.

[0103] In addition, refer to Figure 2 or Figure 4 As shown, in this embodiment, based on the flared section 124 being provided at the bottom end of the gripping portion 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 operating portion 110), and the protrusion 230 protrudes toward the peripheral side of the image processing device 200.

[0104] On the one hand, the raised portion 230 is convenient for the operator to hold, which helps to quickly and smoothly plug and unplug the image processing device 200, and realize the rapid assembly and disassembly of the image processing device 200. On the other hand, the raised portion 230 is used to cooperate with the flared section 124 to limit the image processing device 200 and accurately locate the axial position of the image processing device 200, that is, the position where the image processing device 200 cooperates with the gripping portion 120 in the axial direction, so as to improve the assembly accuracy of the inspection device 1.

[0105] As for the cooperation between the flared section 124 of the gripping portion 120 and the raised portion 230 of the image processing device 200, in some examples, the raised height of the raised portion 230 may be greater than the outward expansion (the width of the expansion outward) of the corresponding area of ​​the flared section 124, and the raised portion 230 may abut against the end of the flared section 124. In other words, the upper end of the raised portion 230 (the end of the raised portion 230 away from the bottom end of the image processing device 200) may abut against the bottom end surface of the gripping portion 120; in other examples, the raised height of the raised portion 230 may be less than the widening amount of the corresponding area of ​​the flared section 124, and the raised portion 230 may extend into the flared section 124 for 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, as an embodiment, the protrusion 230 at the bottom of the image processing device 200 may be protruded on the side of the image processing device 200 facing away from the operating portion 110, that is, the protrusion 230 corresponds to the side of the gripping portion 120 facing away from the operating portion 110. As mentioned above, when in use, the operating portion 110 of the operator 100 extends toward the target part in the body, and the side of the gripping portion 120 facing away from the operating portion 110 faces the operator. By arranging the protrusion 230 on the side of the image processing device 200 facing away from the operating portion 110, it is convenient for the operator to observe the protrusion 230, which is conducive to smooth and rapid assembly of the image processing device 200.

[0107] During surgery, liquid will enter the target part of the body from the mirror tube 112 of the manipulator 100, and the liquid in the body will also flow along the mirror tube 112 or the dilator to the gripping part 120. Therefore, usually more liquid is attached to the side of the gripping part 120 facing the manipulating part 110. Figure 6 As shown in the figure, Figure 1 In the side view structure of the inspection device, the outward expansion degree of the flared section 124 of the holding portion 120 facing the operating portion 110 may be greater than the outward expansion degree of the flared section 124 on the side facing away from the operating portion 110. In this way, the flared section 124 on the side of the holding portion 120 facing the operating portion 110 may guide the liquid flowing along the outer wall of this side of the holding portion 120 in a direction away from the holding portion 120, thereby preventing the liquid from entering the accommodating cavity 120a and preventing the liquid from contaminating the image processing device 200.

[0108] Figure 7 for Figure 1 Another perspective of the inspection device in the exploded structure diagram. Figure 7 As shown, on the basis of providing the flared section 124 at the bottom end of the grip portion 120, in this embodiment, a guide groove 125 may be provided on the outer wall of the grip portion 120, and the guide groove 125 extends from the top end of the grip portion 120 (the end where the grip portion 120 is connected to the operating portion 110) to the bottom end of the grip portion 120, for example, the guide groove 125 may extend along the axial direction of the grip portion 120. Liquid flowing along the outer wall surface of the operating portion 110 to the outer wall surface of the grip portion 120 may enter the guide groove 125 and flow along the guide groove 125, and the guide groove 125 may guide and restrict the liquid, and cooperate with the flared section 124 at the bottom end of the grip portion 120 to prevent the liquid from entering the accommodating cavity 120a from the outer wall surface of the grip portion 120 (the bottom end of the grip portion 120 or the joint seam between the split parts).

[0109] Exemplarily, the guide groove 125 may be an inwardly recessed groove on the outer wall of the gripping portion 120, or the guide groove 125 may be surrounded by a guide strip protruding from the outer wall of the gripping portion 120. By providing the guide groove 125 on the outer wall of the gripping portion 120, an uneven surface is formed on the outer wall of the gripping portion 120, which can also increase the friction when the operator grips and prevent the inspection device 1 from slipping.

[0110] Since there is a lot of liquid attached to the operating part 110 and under the action of gravity, the liquid flows to the lower part of the operating part 110 and flows along the outer wall surface of the operating part 110 to the side of the holding part 120 facing the operating part 110. There is more liquid accumulated on the outer wall of the holding part 120 facing the operating part 110. Therefore, the guide groove 125 can be set on the side of the holding part 120 facing the operating part 110, that is, the guide groove 125 can be located on the side of the holding part 120 facing away from the operating part 110.

[0111] In addition, continue to refer to Figure 7 As shown in the figure, the dotted frame on the outer wall of the image processing device 200 shows the position where the lens 240 of the image processing device 200 is located. A light-transmitting plate can be provided at this position of the housing of the image processing device 200 so that light can pass through the light-transmitting plate and enter the lens 240. The lens 240 of the image processing device 200 is usually arranged on the side of the image processing device 200 facing the operating part 110, and the lens 240 can be located at the top of the image processing device 200 close to the operating part 110. Such an arrangement facilitates exposing the light-collecting surface of the lens 240 to the opening of the expansion wing 114 of the expander (see Figure 4 ) so that the lens 240 can collect images of the target part in the body.

[0112] When the image processing device 200 is used with an endoscope having a mirror tube 112, in some embodiments, an observation window 126 may be provided on a side wall of the gripping portion 120 facing the operating portion 110, and the observation window 126 corresponds to the lens 240 of the image processing device 200. For example, the observation window 126 may be provided at the top of the gripping portion 120 close to the operating portion 110, so that the lens 240 of the image processing device 200 is exposed in the observation window 126. In this way, on the basis of taking images of the target part of the body through the mirror tube 112, the lens 240 of the image processing device 200 may also be used to take images of superficial tissues. Taking a hysteroscope as an example, the lens 240 of the image processing device 200 may take images around the uterine cavity, which helps doctors make more comprehensive judgments and can more accurately locate the position of the mirror tube 112.

[0113] As for the connection between the image processing device 200 and the holding portion 120, the inner wall surface of the holding portion 120 may be provided with a first connecting portion (not shown in the figure), and the outer wall surface of the image processing device 200 may be provided with a second connecting portion (not shown in the figure), and the positions of the first connecting portion and the second connecting portion correspond to each other. Through the matching connection between the first connecting portion and the second connecting portion, the image processing device 200 is fixed in the accommodating cavity 120a of the holding portion 120.

[0114] As an embodiment, the image processing device 200 and the holding portion 120 can be connected by a snap-fitting manner. The first connecting portion provided on the inner wall surface of the holding portion 120 can be a first snap-fitting portion, and the second connecting portion provided on the outer wall surface of the image processing device 200 can be a second snap-fitting portion. The first snap-fitting portion and the second snap-fitting portion are snap-fitted to realize the connection between the image processing device 200 and the holding portion 120.

[0115] Exemplarily, one of the first clamping portion and the second clamping portion may be a clamping protrusion, and the other may be a clamping groove, and the clamping protrusion is clamped into the clamping groove to clamp the image processing device 200 into the accommodating cavity 120a of the gripping portion 120. For example, the inner wall surface of the gripping portion 120 is provided with a clamping groove, and the outer wall surface of the image processing device 200 is provided with a clamping protrusion.

[0116] The first clamping portion may be located on the inner top wall of the gripping portion 120 (the inner wall surface of one end of the gripping portion 120 facing the operating portion 110), and correspondingly, the second clamping portion may be located on the top end surface of the image processing device 200 (the end surface of one end of the image processing device 200 facing the operating portion 110). Alternatively, the first clamping portion may also be located on the inner side wall of the gripping portion 120, and correspondingly, the second clamping portion may be located on the outer side wall of the image processing device 200.

[0117] In addition, the image processing device 200 can be installed in the accommodating cavity 120a by pressing and snapping. When installing the image processing device 200, press the image processing device 200 inward, and the second snap-in portion of the image processing device 200 snaps into the first snap-in portion of the holding portion 120, and the image processing device 200 is snapped into the accommodating cavity 120a; when the image processing device 200 needs to be disassembled, press the image processing device 200 again, and the second snap-in portion of the image processing device 200 disengages from the first snap-in portion of the holding portion 120, and the image processing device 200 can be taken out of the accommodating cavity 120a.

[0118] As another embodiment, the image processing device 200 and the holding portion 120 can be connected by magnetic attraction. The first connecting portion provided on the inner wall surface of the holding portion 120 can be a first magnetic attraction portion, and the second connecting portion provided on the outer wall surface of the image processing device 200 can be a second magnetic attraction portion. The first magnetic attraction portion and the second magnetic attraction portion are relative to and attracted to each other to achieve the connection between the image processing device 200 and the holding portion 120.

[0119] Exemplarily, the first magnetic attraction portion and the second magnetic attraction portion may be magnetic parts installed on the outer surfaces of the grip portion 120 and the image processing device 200. The first magnetic attraction portion may be located on the inner top wall of the grip portion 120, and correspondingly, the second magnetic attraction portion may be located on the top surface of the image processing device 200 (the end surface of the image processing device 200 facing the operating portion 110). Alternatively, the first magnetic attraction portion may also be located on the inner side wall of the grip portion 120, and correspondingly, the second magnetic attraction portion may be located on the outer side wall of the image processing device 200.

[0120] It can be understood that the image processing device 200 and the holding portion 120 are connected by snapping or magnetically attracting each other. Since the first snapping portion (second snapping portion) or the first magnetic portion (second magnetic portion) has a fixed position on the holding portion 120 (image processing device 200), it can play a positioning role when the image processing device 200 and the holding portion 120 are connected, thereby ensuring the position accuracy of the image processing device 200.

[0121] When the accommodating cavity 120a of the holding portion 120 is a cylindrical cavity and the image processing device 200 is a cylindrical structure, the image processing device 200 and the holding portion 120 can also be connected by means of threaded matching. The first connecting portion provided on the inner wall surface of the holding portion 120 can be an internal thread, and the second connecting portion 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 holding portion 120.

[0122] Exemplarily, the internal thread on the grip portion 120 can be set close to the top of the grip portion 120, so that the internal thread can avoid the area on the grip portion 120 where the operating member 123 is set; correspondingly, the external thread on the image processing device 200 can also be set close to the top of the image processing device 200, and the external thread can avoid the area on the image processing device 200 where the control panel 220 is set.

[0123] Figure 8 for Figure 1 A structural diagram of an operating handle of an inspection device in one viewing angle; Fig. 9 for Figure 1 A schematic structural diagram of an image processing device in an inspection device.

[0124] In the case where the image processing device 200 is used with an endoscope having a mirror tube 112, since the camera and light source and other devices installed at the far end of the mirror tube 112 need to be electrically connected to the main board in the image processing device 200, Figure 8 As shown, the inner wall surface of the grip portion 120 may be provided with a first electrical contact portion 127, referring to Fig. 9 As shown, a second electrical contact portion 250 may be provided on the outer wall surface of the image processing device 200, the first electrical contact portion 127 and the second electrical contact portion 250 are in contact with each other, the first electrical contact portion 127 may be electrically connected to the device at the far end of the mirror tube 112, and the second electrical contact portion 250 may be electrically connected to the main board in the image processing device 200, thereby realizing signal transmission between the device at the far end of the mirror tube 112 and the main board in the image processing device 200.

[0125] like Figure 8 and Fig. 9 As shown in, in some embodiments, the first electrical contact portion 127 can be disposed on the inner top wall of the holding portion 120, and correspondingly, the second electrical contact portion 250 can be disposed on the top end surface of the image processing device 200 (the end surface of the image processing device 200 facing the operating portion 110). This method can be suitable for the axial docking of the first electrical contact portion 127 and the second electrical contact portion 250 along the holding portion 120, so that pressure is generated between the first electrical contact portion 127 and the second electrical contact portion 250 in the axial direction of the holding portion 120, thereby ensuring that the first electrical contact portion 127 and the second electrical contact portion 250 are in reliable contact with each other.

[0126] Adapting to the axial docking of the first electrical contact portion 127 and the second electrical contact portion 250 along the holding portion 120, the image processing device 200 can be moved along the axial direction of the holding portion 120 and extended into the accommodating cavity 120a. At this time, the image processing device 200 and the holding portion 120 can be connected by snapping or magnetic attraction. In other words, the first connecting portion provided on the inner wall surface of the holding portion 120 can be a first snapping portion or a first magnetic attraction portion, and the second connecting portion provided on the outer wall surface of the image processing device 200 can be a second snapping portion or a second magnetic attraction portion.

[0127] Of course, under the premise that the first electrical contact portion 127 on the inner top wall of the holding portion 120 and the second electrical contact portion 250 on the top surface of the image processing device 200 can be accurately aligned, when the holding portion 120 has a cylindrical receiving cavity 120a and the image processing device 200 is cylindrical, the holding portion 120 and the image processing device 200 can also be connected by means of a spiral fit. In other words, the first connecting portion on the holding portion 120 can be an internal thread arranged on its inner wall surface, and the second connecting portion on the image processing device 200 can be an external thread arranged on its outer wall surface.

[0128] In the case where the gripping portion 120 has a cylindrical receiving cavity 120a and the image processing device 200 is cylindrical, and when the gripping 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 other embodiments, the first electrical contact portion 127 can be arranged on the inner side wall of the gripping portion 120 (in the circumferential direction), and correspondingly, the second electrical contact portion 250 can be arranged on the inner side wall of the image processing device 200 (in the circumferential direction). On the outer wall, the first electrical contact portion 127 and the second electrical contact portion 250 can be in the same horizontal plane. As the image processing device 200 is screwed into the holding portion 120, the first electrical contact portion 127 and the second electrical contact portion 250 are connected along the circumference of the holding portion 120, and pressure is generated between the first electrical contact portion 127 and the second electrical contact portion 250 in the circumferential direction of the holding portion 120 (for example, in the tangential direction of the cross section of the holding portion 120), thereby ensuring that the first electrical contact portion 127 and the second electrical contact portion 250 are in reliable contact with each other.

[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 thereon abuts against the first electrical contact 127 in the grip 120, the image processing device 200 is restricted to the current position in the circumferential direction of the grip 120 and cannot continue to rotate. In this way, the image processing device 200 is positioned in the circumferential direction of the grip 120.

[0130] Exemplarily, one of the first electrical contact portion 127 and the second electrical contact portion 250 may include a plurality of conductive pillars, and the other may include a plurality of conductive sheets, and the conductive pillars are disposed against the conductive sheets to achieve electrical contact between the two.

[0131] In which, taking the first electrical contact portion 127 being disposed on the inner top wall of the grip portion 120 and the second electrical contact portion 250 being disposed on the top surface of the image processing device 200 as an example, the first electrical contact portion 127 on the inner top wall of the grip portion 120 includes a conductive column (see Figure 8 ), the second electrical contact portion 250 on the top surface of the image processing device 200 includes a conductive sheet (see Fig. 9 ), so that it is convenient for the conductive column to pass through the operating portion 110 and extend out to the top surface of the holding portion 120, and the conductive column can be electrically connected to the device at the far end of the mirror tube 112 through the cable arranged in the operating portion 110.

[0132] For the case where the first electrical contact portion 127 is arranged on the inner wall of the holding portion 120 and the second electrical contact portion 250 is arranged on the outer wall of the image processing device 200, the first electrical contact portion 127 may include a conductive column and the second electrical contact portion 250 may include a conductive sheet, or the first electrical contact portion 127 may include a conductive sheet and the second electrical contact portion 250 may include a conductive column. In this case, the cable arranged in the operating portion 110 may be led out to the accommodating cavity 120a of the holding portion 120 and connected to the first electrical contact portion 127.

[0133] Fig.10 for Figure 1 The structure diagram of the operating handle of the inspection device in another perspective. Fig.10 As shown, in some embodiments, a support portion 128 may be further provided on the inner wall of the holding portion 120. The support portion 128 may protrude from the inner wall of the holding portion 120. The support portion 128 is used to support the image processing device 200. That is, the outer wall of the image processing device 200 may abut against the support portion 128.

[0134] In this way, the support portion 128 can be used to position the image processing device 200 to prevent the image processing device 200 from shaking in the accommodating cavity 120a, ensure that the image processing device 200 is firmly fixed, and also help to align the second electrical contact portion 250 on the image processing device 200 with the first electrical contact portion 127 in the holding portion 120.

[0135] As an example, the support portion 128 may include a support bar 128a arranged on the inner wall of the holding portion 120. The support portion 128 may include at least two support bars 128a, and the support bars 128a are arranged at intervals. For example, the support portion 128 may include two, three, four or even more support bars 128a arranged at intervals. The outer side wall of the image processing device 200 abuts against the support bar 128a to position the image processing device 200.

[0136] The support bar 128a may extend along the length direction of the gripping portion 120. The support bar 128a may support the image processing device 200 and may also guide the image processing device 200. To this end, a guide groove (not shown in the figure) may be provided on the outer wall of the image processing device 200. The guide groove may be, for example, a recessed groove on the outer wall of the image processing device 200 or a groove surrounded by a raised guide bar on the outer wall of the image processing device 200. The guide groove may extend along the length direction of the image processing device 200. When the image processing device 200 is assembled, the support bar 128a on the inner wall of the gripping portion 120 extends into the guide groove on the outer wall of the image processing device 200, and the support bar 128a slides along the guide groove to guide the image processing device 200, thereby ensuring that the image processing device 200 is accurately aligned.

[0137] As mentioned above, in some embodiments, especially for an endoscope equipped with a mirror tube 112, a pipeline assembly 130 is also arranged in the manipulator 100, and further reference is made to Fig.10 The pipeline assembly 130 may include a liquid inlet pipe 131 and a liquid outlet pipe 132, both of which extend into the operating part 110 of the operator 100 and are connected to the mirror tube 112. The liquid inlet pipe 131 is used to transport liquid into the mirror tube 112 so that the liquid enters the target part of the body through the mirror tube 112. The liquid outlet pipe 132 is used to discharge the liquid in the mirror tube 112 so that the liquid that flows back to the mirror tube 112 in the body is discharged to the outside of the inspection device 1 through the liquid outlet pipe 132.

[0138] Taking the application of the inspection device 1 in hysteroscopy as an example, the liquid inlet tube 131 can be used to transport uterine distension fluid into the scope tube 112. The uterine distension fluid is sprayed into the uterine cavity from the distal end of the scope tube 112. The uterine distension fluid in the uterine cavity can also flow back into the scope tube 112 and be discharged through the liquid outlet tube 132.

[0139] Reference Fig.10 As shown, in this embodiment, the liquid inlet pipe 131 and the liquid outlet pipe 132 in the operating part 110 can extend into the gripping part 120, and the liquid inlet pipe 131 and the liquid outlet pipe 132 can extend along the inner wall surface of the gripping part 120 and extend out from the open bottom end of the gripping part 120. In this way, the liquid inlet pipe 131 and the liquid outlet pipe 132 are completely sealed in the housing of the operator 100, and the operator 100 can limit and protect the liquid inlet pipe 131 and the liquid outlet pipe 132, and the stability of the liquid inlet pipe 131 and the liquid outlet pipe 132 is better; and the liquid inlet pipe 131 and the liquid outlet pipe 132 are avoided from being exposed outside the gripping part 120, which will not hinder the gripping of the operator, and can also prevent the problem of leakage to the outer wall surface of the gripping part 120 caused by this, and avoid contamination of the operator 100.

[0140] Of course, in other embodiments, the liquid inlet pipe 131 and the liquid outlet pipe 132 may also extend directly from the operating part 110 to the outside of the operator 100. In this case, a recessed portion may be provided on the side wall of the gripping portion 120 facing the operating part 110, and the liquid inlet pipe 131 and the liquid outlet pipe 132 may be accommodated in the recessed portion so as to limit the liquid inlet pipe 131 and the liquid outlet pipe 132 through the recessed portion to avoid obstruction to the operator's grip.

[0141] Taking the example of the liquid inlet pipe 131 and the liquid outlet pipe 132 extending along the inner wall surface of the grip portion 120, the liquid inlet pipe 131 and the liquid outlet pipe 132 can be located on the inner wall surface of the grip portion 120 close to the operating portion 110. In other words, the liquid inlet pipe 131 and the liquid outlet pipe 132 extend along the inner wall surface of the grip portion 120 close to the operating portion 110.

[0142] On the one hand, the liquid inlet pipe 131 and the liquid outlet pipe 132 extend along the same side surface in the holding portion 120. The extension paths of the liquid inlet pipe 131 and the liquid outlet pipe 132 are short and can be extended in a straight line, thereby ensuring smooth flow of liquid in the liquid inlet pipe 131 and the liquid outlet pipe 132. The liquid inlet pipe 131 and the liquid outlet pipe 132 occupy a relatively small space as a whole, which contributes to the miniaturized design of the holding portion 120.

[0143] On the other hand, when in use, the side of the holding portion 120 facing away from the operating portion 110 is usually facing the sky, and the side of the holding portion 120 facing the operating portion 110 is usually facing the ground. By arranging the liquid inlet pipe 131 and the liquid outlet pipe 132 on the inner wall of the holding portion 120 close to the operating portion 110, the side wall of the holding portion 120 can support the liquid inlet pipe 131 and the liquid outlet pipe 132, thereby improving the reliability of the liquid inlet pipe 131 and the liquid outlet pipe 132.

[0144] Exemplarily, the liquid inlet pipe 131 and the liquid outlet pipe 132 can be integrally formed on the inner wall of the grip portion 120. In other words, the liquid inlet pipe 131 and the liquid outlet pipe 132 can be formed relying on the inner wall of the grip portion 120. In this way, the liquid inlet pipe 131 and the liquid outlet pipe 132 have good integrity with the grip portion 120, and the positions of the pipe sections of the liquid inlet pipe 131 and the liquid outlet pipe 132 in the grip portion 120 are fixed, which is convenient for docking with the pipe sections in the operating portion 110, and the pipe sections of the liquid inlet pipe 131 and the liquid outlet pipe 132 in the grip portion 120 are all integrated structures, with better sealing.

[0145] In addition, refer to Fig.10As shown, when the inner side wall of the gripping portion 120 is provided with a support portion 128, the support portion 128 can also be used to separate a separate space for the liquid inlet pipe 131 and the liquid outlet pipe 132. In this case, the support portion 128 can be provided on the peripheral side of the liquid inlet pipe 131 and the liquid outlet pipe 132, and the protrusion height of the support portion 128 is greater than the protrusion height of the liquid inlet pipe 131 and the liquid outlet pipe 132. When the image processing device 200 abuts against the support portion 128, there is a gap between the outer side wall of the image processing device 200 and the liquid inlet pipe 131 and the liquid outlet pipe 132, which can prevent the image processing device 200 from interfering with the liquid inlet pipe 131 and the liquid outlet pipe 132, and avoid damage to the liquid inlet pipe 131 and the liquid outlet pipe 132.

[0146] In the figure, taking the support portion 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, a support bar 128a can be set on the opposite sides of the liquid inlet pipe 131 and the liquid outlet pipe 132, or only one support bar 128a can be set on the opposite sides of the liquid inlet pipe 131 and the liquid outlet pipe 132.
