Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for which protection is claimed, but merely represents the selected embodiments of the present application.

[0035] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0036] In the present application, unless otherwise clearly specified and limited, a first feature being above or below a second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through another feature between them. Moreover, a first feature being above, above, and above a second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being below, below, and below a second feature includes the first feature being directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0037] In addition, in the present application, "proximal" and "distal" refer to the far and near positions of the structure relative to human operation in the use environment, so as to facilitate the description of the positional relationship between components and facilitate understanding; for the same component, "proximal" and "distal" are the relative positional relationship of the component, not absolute; therefore, it should be understood from the perspective of realizing the principles of the present application, and should not deviate from the essence of the present application.

[0038] In the prior art, the circuit board in the endoscope is usually fixed in the handle housing by gluing or bolting. When the endoscope is inspected and repaired, the inspection process is troublesome, which may affect other components in the endoscope and take a long time to inspect and repair. At the same time, when the circuit board is disassembled and installed in the endoscope, the endoscope handle needs to be completely disassembled, which is also troublesome.

[0039] In view of this, the first aspect of the present application provides a circuit board mounting structure for an endoscope, such as Figure 1-Figure 10 As shown, including:

[0040] The mounting seat 10 and the circuit board 20, the mounting seat 10 has a first mounting cavity 11, and the circuit board 20 is installed in the first mounting cavity 11; the mounting seat 10 is inserted into the endoscope handle, and at least part of the mounting seat 10 is located outside the endoscope handle.

[0041] In the above scheme, the mounting seat 10 is cylindrical as a whole, and the mounting seat 10 is a hollow structure. The space of the hollow structure partially forms a first mounting cavity 11, and the first mounting cavity 11 is arranged along the axial direction of the mounting seat 10. The circuit board 20 can be installed on the cavity wall of the first mounting cavity 11. Exemplarily, the circuit board 20 can be movably installed in the first mounting cavity 11 and abut against the components in the endoscope handle so that the circuit board 20 is kept in the first mounting cavity 11; it can also be installed in the first mounting cavity 11 by screw fixing; it can also be installed in the first mounting cavity 11 by gluing. Here, there is no restriction on the installation method of the circuit board 20 in the first mounting cavity 11.

[0042] The circuit board installation structure of the present application is achieved by first installing the circuit board 20 into the mounting seat 10, and then plugging the mounting seat 10 into the endoscope handle. The distal end of the mounting seat 10 is plugged into the endoscope handle, and the proximal end is located outside the endoscope handle; the mounting seat 10 can also be located entirely outside the endoscope handle, specifically, the distal end of the mounting seat 10 is plugged into the endoscope handle. The circuit board 20 is installed in the endoscope handle through the mounting seat 10. When the circuit board 20 needs to be disassembled and assembled later, it is only necessary to disassemble and assemble the mounting seat 10 from the endoscope handle, and there is no need to disassemble and assemble the endoscope handle, which reduces the disassembly and assembly process of the endoscope handle and speeds up the disassembly and assembly of the circuit board 20.

[0043] According to some optional embodiments, the mounting seat 10 further includes a second mounting cavity 12 , in which a connector 30 is installed; the first mounting cavity 11 is communicated with the second mounting cavity 12 , and the connector 30 is connected to the circuit board 20 .

[0044] In the above scheme, the mounting seat 10 is further provided with a second mounting cavity 12 in the axial direction, and the first mounting cavity 11 is located at the distal end of the mounting seat 10, so that the circuit board 20 can be inserted into the endoscope handle; the second mounting cavity 12 is located at the proximal end of the mounting seat 10, and the connector 30 is installed in the second mounting cavity 12, and the external electrical connector can be connected to the connector 30 to achieve electrical connection with the endoscope handle and transmit data.

[0045] In the present application, the circuit board 20 and the connector 30 are fixedly connected together, and both the circuit board 20 and the connector 30 are located in the mounting seat 10. The connector 30 can be a USB interface, a type-c interface, etc. The connector 30 is integrated with the circuit board 20, and there is no need to set two circuit boards 20, which improves the compactness of the structure. When disassembling and assembling the connector 30, you only need to pull the circuit board 20, and you can take the connector 30 out together for inspection, which is quick and convenient.

[0046] According to some optional embodiments, a step 13 is provided at the proximal end of the plug-in section of the mounting seat 10. When the mounting seat 10 is plugged with the endoscope handle, the step 13 abuts against the proximal end of the endoscope handle.

[0047] In the above scheme, the portion of the mounting seat 10 inserted into the endoscope handle is the plug-in section, and a step 13 is provided on the outer wall of the plug-in section. Exemplarily, in the radial direction of the mounting seat 10, multiple steps 13 may be provided at intervals on the outer wall of the plug-in section. When the mounting seat 10 is inserted into the endoscope handle, the step 13 may abut against the proximal end of the endoscope handle to limit the position. The step 13 provided on the mounting seat 10 limits the maximum insertion depth of the mounting seat 10 in the endoscope handle; at the same time, the abutment of the step 13 with the endoscope handle improves the sealing connection performance between the mounting seat 10 and the endoscope handle.

[0048] According to some optional embodiments, at least one limiting surface 14 is provided on the outer wall of the plug-in section of the mounting seat 10, and the limiting surface 14 is used to limit the rotation of the mounting seat 10 relative to the endoscope handle.

[0049] In the above scheme, at least one limiting surface 14 is set on the outer wall of the plug-in end of the mounting seat 10. The limiting surface 14 can be a plane or an angular surface. When the mounting seat 10 is plugged into the endoscope handle, the setting of the limiting surface 14 limits the rotation of the mounting seat 10 in the endoscope handle.

[0050] According to some optional embodiments, the cross section of the mounting seat 10 along its width direction is trapezoidal.

[0051] In the above scheme, the extension direction of the mounting base 10 is the length direction, and the direction perpendicular to the extension direction is the width direction. The cross-section of the mounting base 10 in the width direction is a trapezoid. This arrangement can prevent the mounting base 10 from rotating in the endoscope handle on the one hand, and improve the compactness of the assembly between the circuit board 10 and the mounting base 10 on the other hand.

[0052] A second aspect of the present application provides an endoscope handle, comprising an endoscope handle and the above-mentioned circuit board mounting structure, wherein a mounting hole 41 is provided on the endoscope handle, and the circuit board mounting structure can be detachably mounted in the mounting hole 41 .

[0053] In the above scheme, a mounting hole 41 is provided on the endoscope handle, and the mounting seat 10 can be installed in the mounting hole 41, and the mounting seat 10 and the mounting hole 41 are detachably connected. Exemplarily, the mounting seat 10 and the mounting hole 41 can be interference connection, the mounting seat 10 can be connected to the mounting hole 41 by threading, and the mounting seat 10 and the mounting hole 41 can also be buckled. Through the detachable connection between the mounting seat 10 and the endoscope handle, the detachable installation of the circuit board mounting structure and the endoscope handle is realized. When the circuit board is inspected and repaired, only the circuit board mounting structure needs to be removed from the endoscope handle, and the endoscope handle does not need to be disassembled.

[0054] According to some optional embodiments, the circuit board mounting structure is mounted on the proximal end of the endoscope handle.

[0055] In the above scheme, the mounting seat 10 is installed at the proximal end of the endoscope handle. Specifically, the mounting seat 10 is arranged at one end of the endoscope handle where the traction wheel is installed, and the mounting seat 10 is located on one side of the traction wheel. This can avoid the traction rope in the endoscope handle and reduce the interference of the circuit board 20, the mounting seat 10, and cables on the traction rope.

[0056] According to some optional embodiments, the endoscope handle has an electrical connection line 42, which is electrically connected to the circuit board 20, and a reserved section 421 is provided at one end of the electrical connection line 42 connected to the circuit board 20. The reserved section 421 can extend out of the endoscope handle along with the circuit board 20.

[0057] In the above scheme, the electrical connection line 42 can be a cable, etc., one end of the electrical connection line 42 is connected to other components in the endoscope handle, and the other end is connected to the circuit board 20. A reserved section 421 is provided at one end of the electrical connection line 42 connected to the circuit board 20. When the mounting seat 10 and the circuit board 20 mounted therein are removed from the endoscope handle, the reserved section 421 of the electrical connection line 42 can be pulled out of the endoscope handle along with the circuit board 20, and the endoscope handle does not need to be opened to remove the electrical connection line 42 from the circuit board 20. Moreover, when the electrical connection line 42 is pulled out of the endoscope handle along with the circuit board 20, the electrical connection line 42 is not easily broken.

[0058] According to some optional embodiments, a stopper 43 is provided on the plug-in path of the circuit board mounting structure of the endoscope handle, and the stopper 43 can abut against the circuit board 20 to keep the circuit board 20 in the first mounting cavity 11 of the mounting base 10 .

[0059] In the above scheme, in some optional embodiments, if the circuit board 20 is not fixed in the mounting seat 10, in order to prevent the circuit board 20 from moving out of the mounting seat 10 after the mounting seat 10 is inserted into the endoscope handle, the endoscope handle is provided with a stopper 43 on the plug-in path of the mounting seat 10, and the distal end of the circuit board 20 in the mounting seat 10 can abut against the stopper 43, thereby limiting the movement of the circuit board 20 in the mounting seat 10 and avoiding the installation between the circuit board 20 and the mounting seat 10, thereby speeding up the assembly process of the endoscope handle.

[0060] A third aspect of the present application provides an endoscope, comprising the above-mentioned endoscope handle.
