[0042] Please see Figures 1 to 3 An embodiment of this application provides an endoscope with a detachable display screen, including: a control handle 100, a display screen 800, and a snap-fit ​​assembly 900.

[0043] Please combine Figures 1 to 10Specifically, a connector 16 protrudes from the outer wall of the operating handle 100, and a first connecting terminal 161 is provided on the connector 16. The display screen 800 is detachably connected to the operating handle 100. When needed, the display screen 800 can be separated from the operating handle 100, thereby reducing the packaging volume and facilitating packaging, transportation, or carrying. The display screen 800 includes a housing 81 and a second connecting terminal 82. A connecting groove 801 is provided on the housing 81, and the connecting groove 801 is inserted into the connector 16 to realize the detachable assembly between the operating handle 100 and the display screen 800. The fixed end of the second connecting terminal 82 is fitted into the inner cavity 802 of the housing 81, and the plug-in end of the second connecting terminal 82 extends into the connecting groove 801. The second connecting terminal 82 is inserted into the first connecting terminal 161 to make the circuit between the operating handle 100 and the display screen 800 conductive.

[0044] The inner wall of the connecting groove 801 is provided with a snap-fit ​​channel 803 communicating with the inner cavity 802 of the housing 81. The snap-fit ​​assembly 900 has a first part and a second part. The first part of the snap-fit ​​assembly 900 is installed in the inner cavity 802 of the housing 81 and is fixedly connected to the inner wall of the housing 81. The second part of the snap-fit ​​assembly 900 is accommodated in the snap-fit ​​channel 803 and is connected to the first part of the snap-fit ​​assembly 900. The second part of the snap-fit ​​assembly 900 can move relative to the snap-fit ​​channel 803, thereby extending or retracting into the snap-fit ​​channel 803. The second part of the snap-fit ​​assembly 900 is used to snap or separate from the connector 16 to lock or unlock the connector 16. It should be noted that the snap-fit ​​assembly 900 enables quick assembly and disassembly between the display screen 800 and the operating handle 100, which not only improves the stability of the connection between the display screen 900 and the operating handle 100, but also facilitates the assembly, disassembly, use, transportation, or carrying of the endoscope.

[0045] Please see Figures 3 to 10 In one embodiment, the housing 81 includes a front housing 811 and a rear cover 812 fixedly assembled with the front housing 811. A connecting groove 801 is provided on the outer side wall of the rear cover 812, and the connecting groove 801 has an opening 804 for inserting a connector 16, allowing the connector 16 to enter the connecting groove 801 through the opening 804 and be detachably connected to the rear cover 812.

[0046] In one embodiment, a first limiting groove 805 extending along a first direction X is provided on the side wall of the connecting groove 801, and the first end 8051 of the first limiting groove 805 communicates with the opening 804. A first limiting part 162 is provided on the side wall of the connector 16, and the first limiting part 162 passes through the first end of the first limiting groove 805 into the first limiting groove 805. The first limiting part 162 is used to insert into the first limiting groove 805, and limits the connector 16 in the second direction Z, confining the connector 16 within the connecting groove 801, thereby improving the stability of the fit between the connector 16 and the connecting groove 801.

[0047] In some embodiments, the detachable assembly between the display screen 800 and the operating handle 100 can be achieved by simultaneously inserting the first limiting part 162 into the first limiting groove 805 and locking it through the snap-fit ​​structure 900. Alternatively, the detachable assembly between the display screen 800 and the operating handle 100 can be achieved by inserting the first limiting part 162 into the first limiting groove 805 alone, in which case there is an interference fit between the first limiting part 162 and the first limiting groove 805.

[0048] It should be noted that the first limiting part 162 has a proximal end 1621 and a distal end 1622, wherein the proximal end 1621 is the end closer to the operating handle 100, and the distal end 1622 is the end farther away from the operating handle 100. The first end 8051 of the first limiting groove 805 is the end closer to the root of the connector 16 after the connector 16 is assembled with the connecting groove 801. The second end 8052 of the first limiting groove 805 is the end closer to the distal end 1622 after the connector 16 is assembled with the connecting groove 801. When the first limiting part 162 is assembled with the first limiting groove 805, the distal end 1622 of the first limiting part 162 first assembles with the first end 8051 of the first limiting groove 805, and then continues to push the first limiting part 162 towards the second end 805 of the first limiting groove 805, so that the distal end 1622 of the first limiting part 162 abuts against the inner wall of the second end 8052 of the first limiting groove 805.

[0049] Please continue reading. Figures 3 to 10In one embodiment, the cross-sectional dimension of the proximal end 1621 of the first limiting portion 162 is larger than the cross-sectional dimension of its distal end 1622. Correspondingly, the opening size of the first end 8051 of the first limiting groove 805 is larger than the opening size of its second end 8052. This arrangement makes it easier for the distal end 1622 of the first limiting portion 162 to be inserted into the first end 8051 of the first limiting groove 805, which improves the ease of assembly between the first limiting portion 162 and the first limiting groove 805. In addition, the setting that the cross-sectional dimension of the proximal end 1621 of the first limiting portion 162 is larger than the cross-sectional dimension of its distal end 1622 makes the first limiting portion 162 as a whole wedge-shaped structure. The wedge-shaped structure has lower requirements for the fitting process of the first limiting groove 805 and the first limiting portion 162, and the tightness after the first limiting groove 805 and the first limiting portion 162 are inserted is also better, which helps to improve the stability of the assembly between the connector 16 and the connecting groove 801.

[0050] In one embodiment, a second limiting portion 8121 is formed on the sidewall of the connecting groove 801. A second limiting groove 1601 is provided on the sidewall of the connector 16. When the connecting groove 801 and the connector 16 are assembled, the second limiting portion 8121 and the second limiting groove 1601 are adapted to each other, further limiting the connector 16 in the second direction Z, thereby further improving the stability of the fit between the connector 16 and the connecting groove 801.

[0051] Please combine Figure 3 and Figure 7 In one embodiment, the side of the display screen 800 connected to the connector 16 is the assembly side 80a. The other side of the display screen 800 opposite to the assembly side 80a is the non-assembly side 80b. The thickness H1 of the assembly side 80a is greater than the thickness H2 of the non-assembly side 80b, so that after the display screen 800 is assembled with the operating handle 100, the center of gravity of the display screen 800 is closer to the side where the operating handle 100 is located, thereby further improving the stability of the connection between the display screen 800 and the operating handle 100.

[0052] See Figures 8 to 10 In one embodiment, the display screen 800 further includes: a screen 83, a circuit board, control buttons 84, a connection port 85, a memory expansion port 86, and a dustproof seal 87.

[0053] Specifically, the front cover 811 has a viewing window. The screen 83 is located within the inner cavity 802, and its display face corresponds to the viewing window, allowing the content displayed on the screen 83 to be viewed through the viewing window. The circuit board is connected to the second connection terminal 82, control buttons 84, connection port 85, and memory expansion port 86, and is capable of data transmission, signal transmission, and circuit connection. Multiple control buttons 84 are provided, all located on the front cover 811. The front cover 811 also has a mounting port 810 communicating with the inner cavity 802, with the connection port 85 and memory expansion port 86 located within the mounting port 810. The connection port 85 is a Type-C interface; the memory expansion port 86 is an SD card slot or a TF card slot. The dustproof seal 87 has an anti-detachment foot 871. The anti-detachment foot 871 is connected to the front cover 811 to prevent the dustproof seal 87 from detaching from the front cover 811 after opening, facilitating the resealing of the mounting port 810 after use of the connection port 85 and memory expansion port 86. The anti-slip foot 871 is flexible, which helps to increase the opening angle of the dustproof seal 87, making it easier to use the connection port 85 and the memory expansion port 86.

[0054] Please see Figures 1 to 6 and Figures 11 to 15 In one embodiment, the operating handle 100 has a housing 1, which includes a first housing 11 and a second housing 12 connected to the first housing 11, and a connector 16 connected to the housing 1.

[0055] Specifically, the connector 16 further includes a connecting portion 163 and a cover portion 164. The connecting portion 163 is connected to the first housing 11. The connecting portion 163 has a mounting cavity 1630, and the fixed end of the first connecting terminal 161 is fixedly mounted on the inner wall of the mounting cavity 1630. The cover portion 164 is connected to the second housing 12. When the first housing 11 and the second housing 12 are connected, the cover portion 164 cooperates with the connecting portion 163 to close the mounting cavity 1630. The cover portion 164 is provided with a clearance opening 1640 communicating with the mounting cavity 1630, and the connecting end of the first connecting terminal 161 passes through the clearance opening 1640 so as to be adapted to the second connecting terminal 82 when the connector 16 is assembled with the connecting groove 801. The connecting portion 163 and the cover portion 164 are fixed together by fastening screws to form the connector 16, which facilitates the installation of the first connecting terminal 161.

[0056] Please combine Figure 3 , Figure 7 and Figure 15In one embodiment, the second housing 12 has a protrusion 124 and an extension 125. The first end of the protrusion 124 is connected to the second housing 12, and the second end of the protrusion 124 extends away from the second housing 12. The first end of the extension 125 is connected to the first end of the protrusion 124, and the second end of the extension 125 extends towards the side where the first housing 11 is located and is connected to the cover 164. A limiting recess 12a is formed between the protrusion 124, the extension 125, and the cover 164. When the display screen 800 is assembled with the operating handle 100, a portion of the assembly side 80a of the display screen 800 is accommodated within the limiting recess 12a, allowing the limiting recess 12a to limit the display screen 800, further improving the stability of the connection between the display screen 800 and the operating handle 100.

[0057] Please see Figures 1 to 10 and Figures 16 to 19 In one embodiment, the snap-fit ​​assembly 900 includes a snap-fit ​​base 91, a snap-fit ​​member 92, and an elastic member 93. Specifically, the snap-fit ​​base 91 is installed in the inner cavity 802 of the housing 81 and is fixedly connected to the inner wall of the rear cover 812 by fastening screws. The snap-fit ​​member 92 is movably installed in the snap-fit ​​channel 803. The second end of the snap-fit ​​member 92 extends into the inner cavity 802 of the housing 81, and the first end of the snap-fit ​​member 92 can selectively snap into or separate from the connector 16, thereby realizing the locking and unlocking of the connector 16 and the connecting groove 801. The elastic member 93 is disposed between the second end of the snap-fit ​​member 92 and the snap-fit ​​base 91. The first end of the elastic member 93 is connected to the snap-fit ​​base 91, and the second end of the elastic member 93 is connected to the second end of the snap-fit ​​member 92. The elastic member 93 is used to press the snap-fit ​​member 92 into the first limiting groove 805, so that the snap-fit ​​member 92 extends out of the snap-fit ​​channel 803 and snaps into the connector 16.

[0058] It should be noted that the snap-fit ​​component 900 improves the ease of assembling and disassembling the display screen 800 and the operating handle 100, which is beneficial for the packaging, transportation, and carrying of the endoscope. At the same time, the snap-fit ​​component 900 also ensures the stability of the connection between the display screen 800 and the operating handle 100, preventing the display screen 800 from separating from the operating handle 100 during use.

[0059] In one embodiment, the rear cover 812 is provided with a receiving opening 806 communicating with a snap-fit ​​channel 803. The snap-fit ​​base 91 is provided with a mounting groove 901. The snap-fit ​​member 92 includes: a limiting part 921, a mounting part 922, a snap-fit ​​part 923, and a driving part 924.

[0060] Specifically, the limiting part 921 is housed within the mounting groove 901. The limiting part 921 is located in the inner cavity 802 and engages with the inner wall of the rear cover 812 to limit the position of the snap-fit ​​member 92. The mounting part 922 protrudes from the end face of the limiting part 921 near the bottom of the mounting groove 901 and is connected to the second end of the elastic member 93. The snap-fit ​​part 923 is connected to the end face of the limiting part 921 away from the bottom of the mounting groove 901. The snap-fit ​​part 923 is housed within the snap-fit ​​channel 803 and is movable along the snap-fit ​​channel 803 to extend or retract. The driving part 924 is installed within the receiving opening 806 and connected to the snap-fit ​​part 923. The driving part 924 allows the user to apply force to retract the snap-fit ​​part 923 into the snap-fit ​​channel 803, thereby manually controlling the separation of the connector 16 from the connecting groove 801.

[0061] It should be noted that when manually controlling the latching component 92, since the driving part 924 is housed within the receiving opening 806, the user can directly apply external force to the driving part 924. This forces the driving part 924 to move the latching part 923, the mounting part 922, and the limiting part 921 synchronously, compressing the elastic member 93. Consequently, the latching component 92 separates from the connector 16 and retracts into the latching channel 803. After the external force is removed, the latching component 92 resets under the elastic force of the elastic member 93, so that when the display screen 800 is reconnected to the operating handle 100, the latching component 92 automatically latches onto the connector 16 under the elastic force of the elastic member 93. This design makes the latching or disengagement of the connector 16 from the connecting slot 801 more convenient, effectively improving the efficiency of assembling and disassembling the display screen 80 and the operating handle 100.

[0062] In other embodiments, the driving part 924 may be connected only to the latching part 923, or only adjacent to the limiting part 921, or connected to both the latching part 923 and the limiting part 921. It only needs to satisfy the requirement that applying an external force to the driving part 924 can synchronously move the latching part 923, the limiting part 921, and the mounting part 922. In this embodiment, the driving part 924 is integrally formed with the latching part 923 and the limiting part 921.

[0063] Please see Figures 16 to 19 In one embodiment, the mounting portion 922 is provided with a mounting hole 902. The second end of the elastic member 93 extends into the mounting hole 902 and is connected to the bottom of the mounting hole 902. A connecting post 911 is provided on the end face of the mounting groove 901 opposite to the mounting hole 902, and the first end of the elastic member 93 is sleeved on the connecting post 911.

[0064] It should be noted that the first end of the elastic element 93 is sleeved on the connecting post 911. During elastic deformation, the connecting post 911 acts as a guide, preventing accidental deformation or slippage of the first end of the elastic element 93, thus ensuring normal deformation. Furthermore, the second end of the elastic element 93 is inserted into the mounting hole 902. The mounting hole 902 also guides the elastic element 93 during elastic deformation and limits its position, further ensuring normal deformation. In this embodiment, the connecting channel 803 extends along the third direction Y, and the elastic element 93 undergoes elastic deformation along this direction.

[0065] In some other embodiments, the connecting post 911 can be provided on the mounting portion 922, and correspondingly, the mounting hole 902 can be provided on the side wall of the mounting groove 901. Alternatively, the connecting post 911 can be provided on both the mounting portion 922 and the side wall of the mounting groove 901, with the first and second ends of the elastic member 93 respectively fitted onto the two connecting posts 911. Alternatively, the mounting hole 902 can be provided on both the mounting portion 922 and the side wall of the mounting groove 901, with the first and second ends of the elastic member 93 respectively installed in the two mounting holes 902. Alternatively, the first end of the elastic member 93 can be fixedly connected to the inner wall of the mounting groove 901, and the second end of the elastic member 93 can be fixedly connected to the mounting portion 922. That is, it is only necessary to ensure that the first end of the elastic member 93 is connected to the snap-fit ​​seat 91, the second end of the elastic member 93 is connected to the snap-fit ​​member 92, and that the elastic member 93 provides elasticity for the snap-fit ​​member 92 to extend out of the snap-fit ​​channel 803. In this embodiment, the elastic element 93 is a spring; in other embodiments, the elastic element 93 is a sheet, a block, or the like.

[0066] Please see Figures 1 to 19 and Figures 16 to 19 In one embodiment, the end face of the snap-fit ​​portion 923 near the connecting groove 801 is a first end face 9231. A snap-fit ​​connector 9232 is provided on the first end face 9231, and the snap-fit ​​connector 9232 extends towards the connecting groove 801. The snap-fit ​​connector 9232 has a first limiting end face 9232a, and the first limiting end face 9232a intersects with the first end face 9231 to jointly form an open limiting notch 9233. A snap-fit ​​groove 1620 adapted to the snap-fit ​​connector 9232 is provided on the side wall of the first limiting portion 162. The first limiting portion 162 consists of two limiting strips symmetrically arranged on the outer side wall of the connector 16, and the snap-fit ​​groove 1620 divides the first limiting portion 162 near the snap-fit ​​assembly 900 to form a first limiting protrusion 1623 and a second limiting protrusion 1624. The snap-fit ​​connector 9232 engages with the snap-fit ​​groove 1620 to limit the first limiting part 162 in the first direction X. The second limiting protrusion 1624 is adapted to the limiting notch 9233.

[0067] In one embodiment, the end of the snap-fit ​​connector 9232 away from the first limiting end face 9232a is provided with a wedge-shaped end face 9232b. The distal end of the first limiting protrusion 1623 has a first inclined end face 1625. The distal end of the second limiting protrusion 1624 has a second inclined end face 1626, and the proximal end of the second limiting protrusion 1624 has a second limiting end face 1627. The wedge-shaped end face 9232b, the first inclined end face 1625, and the second inclined end face 1626 have the same inclination direction.

[0068] It should be noted that during the engagement of the first limiting part 162 and the first limiting groove 805, the first inclined end face 1625 is used to engage with the wedge-shaped end face 9232b to press the snap-fit ​​connector 9232 into the snap-fit ​​channel 803, causing the snap-fit ​​connector 9232 to retract into the snap-fit ​​channel 803, while simultaneously compressing the elastic element 93; when the snap-fit ​​connector 9232 moves to the position of the snap-fit ​​groove 1620, the snap-fit ​​connector 9232 engages with the snap-fit ​​groove 1620 under the elastic force of the elastic element 93. At this time, the second inclined end face 1626 approaches the wedge-shaped end face 9232b, completely accommodating the snap-fit ​​connector 9232.

[0069] It should be noted that when the connector 16 and the connecting groove 801 are assembled together, the distal end 1622 of the first limiting part 162 is aligned with the first end 8051 of the first limiting groove 805, and the connector 16 is pushed along the first direction X, so that the distal end 1622 of the first limiting part 162 moves toward the second end 8052 of the first limiting groove 805. When the first inclined end face 1625 abuts against the wedge-shaped end face 9232b, the connector 162 continues to be pushed along the first direction X. Through the interaction between the first inclined end face 1625 and the wedge-shaped end face 9232b, the pushing force is transformed into a force that compresses the snap-fit ​​connector 9232 and moves it into the snap-fit ​​channel 803, causing the snap-fit ​​connector 9232 to move into the snap-fit ​​channel 803 and compress the elastic member 93. The connector 16 continues to be pushed along the first direction X until the snap-fit ​​connector 9232 engages with the snap-fit ​​groove 1620 under the elastic force of the spring 93. Then the push on the connector 16 stops. At this time, the first limiting end face 9232a abuts against the second limiting end face 1627, and the second inclined end face 1626 fits against the wedge-shaped end face 9232b. Thus, the first limiting groove 805 and the first limiting part 162 complete the engagement.

[0070] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0071] 1) The display screen 900 and the operating handle 100 are detachably connected, allowing the endoscope to separate the display screen 800 from the operating handle 100, thereby reducing the packaging volume and facilitating packaging, transportation, or carrying; while the snap-fit ​​component 900 allows for quick assembly and disassembly of the display screen 800 and the operating handle 100, which not only improves the stability of the connection between the display screen 900 and the operating handle 100, but also makes it more convenient for the endoscope to be assembled, disassembled, used, transported, or carried.

[0072] 2) By cooperating with the first limiting part 162 and the first limiting groove 805, the connector 16 is limited in the second direction Z, and the connector 16 is confined in the connecting groove 801, thereby improving the stability of the connection between the connector 16 and the connecting groove 801.

[0073] 3) The cross-sectional dimension of the proximal end 1621 of the first limiting part 162 is larger than the cross-sectional dimension of its distal end 1622. Correspondingly, the opening dimension of the first end 8051 of the first limiting groove 805 is larger than the opening dimension of its second end 8052. This arrangement makes it easier for the distal end 1622 of the first limiting part 162 to align with the first end 8051 of the first limiting groove 805, which is beneficial to improving the ease of assembly between the first limiting part 162 and the first limiting groove 805. In addition, when the display screen 800 is assembled with the operating handle 100, the connector 16 also plays a supporting role for the display screen 800. The setting that the cross-sectional dimension of the proximal end 1621 of the first limiting part 162 is larger than the cross-sectional dimension of its distal end 1622 makes the first limiting part 162 wedge-shaped as a whole. Under the gravity of the display screen 800, the first limiting part 162 can more stably and firmly support the display screen 800, further improving the stability of the assembly between the connector 16 and the connecting groove 801.

[0074] 4) A protrusion 124 and an extension 125 are provided on the second housing 12, forming a limiting recess 12a between the protrusion 124, the extension 125, and the cover 164. When the display screen 800 is assembled with the operating handle 100, a portion of the mounting side 80a of the display screen 800 is accommodated in the limiting recess 12a, so that the limiting recess 12a can limit the display screen 800, further improving the stability of the connection between the display screen 800 and the operating handle 100.

[0075] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
