[0033] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0034] Reference Figure 1 and Figure 2 In one embodiment of this utility model, the endoscope handle has its two ends connected to the endoscope sheath 100 and the cable 200, respectively. The handle includes a main shell 1 and a first shielding shell 2 installed on one end of the main shell 1 near the end of the endoscope sheath 100. The first shielding shell 2 houses an image acquisition module 3, and the main shell 1 houses a circuit module 4. The image acquisition module 3 and the circuit module 4 are electrically connected through a connector 5. The main shell 1 includes an assembly space adjacent to the first shielding shell 2 and extending in a predetermined direction. The circuit module 4 is housed in the assembly space in a predetermined direction, wherein the predetermined direction is perpendicular to the imaging surface of the image acquisition module 3.

[0035] It should be noted that in this embodiment, the predetermined direction is perpendicular to the imaging surface of the image acquisition module 3, but this does not represent absolute perpendicularity in a strictly defined sense. In fact, based on actual production and installation errors, a certain degree of error should be allowed in the perpendicularity of this embodiment. Furthermore, for the circuit module 4, which typically includes a PCB board that carries various electronic components, in one embodiment, the extension direction of the PCB board can be defined as the assembly orientation of the circuit module 4.

[0036] In some comparative designs, the main housing of the endoscope handle is bent, and the circuit module and image acquisition module are located in two opposing bent sections. The imaging surfaces of the circuit module and image acquisition module are also adaptively set at a (non-right angle). This requires a relatively long insertion distance for the connector to connect the circuit module and image acquisition module, leading to a weak connection and easy detachment. In this embodiment, the circuit module 4 is assembled along a predetermined direction, which is perpendicular to the imaging surface of the image acquisition module 3. This allows the connector 5 to connect the circuit module 4 and image acquisition module 3 with a shorter insertion distance, improving the reliability of the electrical connection between the two.

[0037] The image acquisition module 3 can be a CMOS or CCD image sensor. The main housing 1 is a metal housing, and the first shielding housing 2 is an insulating housing, which can specifically be a plastic housing. Since the main housing 1 is a metal housing, the use of an insulating housing on the outside of the image acquisition module 3 when receiving optical signals can effectively prevent signal crosstalk and ensure the normal operation of the image acquisition module 3.

[0038] Reference Figure 2 Furthermore, the handle also includes a mounting cylinder 6 extending along a predetermined direction and installed within the main housing 1, with an assembly space formed within the mounting cylinder 6. The main housing 1 includes a first main housing segment 11 adjacent to the first shielding shell 2 and a second main housing segment 12 adjacent to the cable 200. The assembly space is formed within the first main housing segment 11. The extending direction of the second main housing segment 12 forms an angle with the predetermined direction, and the inner diameter of the second main housing segment 12 decreases in the direction away from the first main housing segment 11. The configuration of the main housing 1 as a first main housing segment 11 and a second main housing segment 12 improves the ease of installation of the mounting cylinder 6 and the circuit module 4.

[0039] Reference Figure 2 and Figure 3 A sealing element 7 is provided between the main shell 1 and the first shielding shell 2. The main shell 1 and the first shielding shell 2 together press against the sealing element 7 to form a sealed space. The image acquisition module 3 and the circuit module 4 are both located within the sealed space. Therefore, the sealed space formed by the sealing element 7 can ensure the airtightness and watertightness of the handle, and reduce the interference of dust or moisture on the internal circuit module 4 and image acquisition module 3.

[0040] The main shell 1 and the first shielding shell 2 each have a first recess 13 on their insertion end face, and a first abutment 21 on their insertion end face that can be inserted into the first recess 13. A sealing member 7 is disposed in the first recess 13, and the first abutment 21 presses against the sealing member 7 located in the first recess 13 along the insertion direction. The cooperation between the first recess 13 and the first abutment 21 can, on the one hand, fix the sealing member 7 through the first recess 13 and hold the sealing member 7 through the first abutment 21 to ensure a sealing effect; on the other hand, it can position the main shell 1 and the first shielding shell 2 to achieve quick insertion and installation.

[0041] Reference Figures 2 to 4 In this embodiment, a sealing element 7 is provided between the first main shell section 11 and the first shielding shell 2, and between the first main shell section 11 and the second main shell section 12. The first main shell section 11, the second main shell section 12 and the first shielding shell 2 press against the sealing element 7 to form a sealed space. The image acquisition module 3 and the circuit module 4 are both located in the sealed space.

[0042] Specifically, one of the insertion end faces of the first main shell section 11 and the first shielding shell 2 is provided with a first recess 13, and the other insertion end face is provided with a first abutment 21 that can be inserted into the first recess 13. A sealing member 7 is disposed within the first recess 13, and the first abutment 21 presses against the sealing member 7 located within the first recess 13 along the insertion direction. One of the insertion end faces of the first main shell section 11 and the second main shell section 12 is provided with a second recess 14, and the other insertion end face is provided with a second abutment 15. A sealing member 7 is disposed within the second recess 14, and the second abutment 15 presses against the sealing member 7 located within the second recess 14 along the insertion direction. Through the above-described structural arrangement, a sealing effect inside the handle can be ensured. The second abutment 15 can be an abutment surface used to abut against the sealing member 7 located within the second recess 14. The forms of the first recess 13 and the second recess 14 can be specifically designed according to the shape of the sealing member 7.

[0043] For example, in this embodiment, the insertion end face of the first main shell segment 11 is provided with a first recess 13, and the insertion end face of the first shielding shell 2 is provided with a first abutting portion 21 that can be inserted into the first recess 13. The insertion end face of the first main shell segment 11 is provided with a second abutting portion 15, and the insertion end face of the second main shell segment 12 is provided with a second recess 14. In other embodiments, the positions of the first recess 13 and the first abutting portion 21 can be adjusted, and the positions of the second recess 14 and the second abutting portion 15 can also be adjusted.

[0044] Reference Figure 1 and Figure 5In this embodiment, the first shielding shell 2 includes a body part 22 connected to the main shell 1 and a connecting sleeve 23 disposed at one end of the body part 22 away from the main shell 1. The connecting sleeve 23 is used to be threadedly connected to the mirror sheath 100.

[0045] Reference Figure 2 The handle also includes a second shielding shell 8 installed on one end of the main housing 1 adjacent to the cable 200, combined with Figure 6 and Figure 7 The second shielding shell 8 includes an inner protective layer 81 through which a cable 200 passes. The main shell 1 has a connection port for the inner protective layer 81 to be fitted. The inner protective layer 81 has a locking part 811 that abuts against the end of the main shell 1 at the connection port. During assembly, the locking part 811 abuts against the end of the main shell 1 at the connection port to achieve quick positioning of the second shielding shell 8. The second shielding shell 8 is an insulating shell, and can be made of plastic. Since the inner protective layer 81 contains the cable 200, and the cable 200 wraps at least three wires: fiber optic lighting wire, electrical signal input / output wire, and optical signal return wire, and the main shell 1 is made of metal, making the second shielding shell 8 a plastic shell can reduce signal crosstalk to a certain extent.

[0046] Furthermore, the second shielding shell 8 also includes at least two outer wrapping layers 82 sleeved around the outer periphery of the inner protective layer 81. The outer wrapping layers 82 can abut against the end of the main shell 1 at the connection port, and the opposing surfaces of two adjacent outer wrapping layers 82 are provided with interlocking parts 821. In this embodiment, two outer wrapping layers 82 are provided as an example. In other embodiments, other numbers of outer wrapping layers 82 can also be provided. By providing at least two outer wrapping layers 82, and providing interlocking parts 821 between the outer wrapping layers 82, the sealing effect inside the handle can be further ensured, reducing the damage of moisture and dust to the circuit module 4 and image acquisition module 3 inside the handle, and ensuring their normal operation.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
