Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, 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. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0040] The endoscope's main unit and handle are typically connected via a plug-in connector. The main unit has a main unit connector, and the handle has a handle connector. These connectors plug into each other to establish an electrical connection, allowing images to be transmitted to the main unit's screen. When replacing the endoscope's handle, the new handle cannot connect to the original main unit. This is because the new handle connector is incompatible with the original main unit connector. For example, the older main unit connector uses a press-down rotating side contact structure with B electrical connection points, while the new endoscope handle connector uses a locking end-face contact structure with A electrical connection points, secured by a press-down connection. Therefore, the new handle connector is incompatible with the older main unit connector. However, directly replacing the main unit with the new handle would waste the original main unit, resulting in equipment waste.

[0041] In view of this, an embodiment of the present invention provides a conversion connector and an endoscope system. The conversion connector can connect a non-matching operating host and an endoscope handle by changing the electrical connection point. It will be described in detail below.

[0042] Please refer to Figures 1 to 5. The adapter includes a connecting housing 1 and an adapter 2. The adapter 2 is disposed within the connecting housing 1 and has a communicating first end 20 and a second end 21. The first end 20 can be electrically connected to the first host connector 70, and the second end 21 can be electrically connected to the second endoscope connector 80. The adapter 2 enables a compatible connection between the first host connector 70 and the second endoscope connector 80, thereby ensuring normal signal and image transmission and facilitating viewing by medical personnel on the screen of the first host 7. The connecting housing 1 connects to the first host connector 70 and the second endoscope connector 80, physically connecting and fixing them. The connecting housing 1 ensures the stability and reliability of the electrical connection. The connecting housing 1 and the adapter 2 work together to achieve the connection between the non-matching operating host and the endoscope handle.

[0043] Understandably, the first host connector 70 corresponds to the first host 7, and the second endoscope connector 80 corresponds to the second endoscope 8. The first host 7 can be an older model or a newer model relative to the second endoscope 8. Similarly, the second endoscope 8 can be an older model or a newer model relative to the first host 7. The endoscope mentioned here refers to the endoscope handle. In this embodiment, the first host 7 and the second endoscope 8 are not compatible models, so an adapter is needed for connection.

[0044] In this embodiment, the first host 7 is an older model host, the second endoscope 8 is a newer model endoscope, the first host connector 70 is an older model host connector, and the second endoscope connector 80 is a newer model endoscope connector.

[0045] The converter 2 simultaneously connects to the electrical contacts of both the first host connector 70 and the second endoscope connector 80. Since the number and arrangement of the electrical contacts of the first host connector 70 and the second endoscope connector 80 are different, the converter 2 is equipped with a conversion circuit board 22. The conversion circuit board 22 enables complete signal transmission. It matches the electrical contacts of the first host connector 70 by merging or splitting conductive paths and quantities. The conversion circuit board 22 can be a flexible circuit board or a multilayer PCB, with conductive paths designed according to actual conditions. Both the first end 20 and the second end 21 of the converter 2 are connected to the conversion circuit board 22. When a signal is input to the conversion circuit board 22 at the second end 21, the conversion circuit board 22 rectifies or splits the signal and transmits it to the first end 20, thereby displaying an image on the first host 7.

[0046] The first end 20 is matched with the first host connector 70 to ensure a stable connection for signal transmission. Similarly, the second end 21 is matched with the second endoscope connector 80.

[0047] The adapter 2 can be located either outside or inside the connecting housing 1, depending on the model of the first host 7 and the second endoscope 8 being connected. In this embodiment, the adapter 2 is located inside the connecting housing 1, which will be described in detail below.

[0048] The connecting housing 1 has a receiving cavity, and the entire conversion component 2 is disposed within the receiving cavity. Similarly, the structure of the connecting housing 1 can also take various forms, but the parts of the connecting housing 1 that mate with the first host connector 70 and the second endoscope connector 80 need to be compatible with each other. In this embodiment, the connecting housing 1 can be a single piece, or it can be assembled from multiple parts.

[0049] Referring again to Figures 3 and 5, the connecting housing 1 includes a first connecting member 10, a second connecting member 11, and an intermediate connecting member 12. The intermediate connecting member 12 is disposed between the first connecting member 10 and the second connecting member 11. One end of the intermediate connecting member 12 is connected to the first connecting member 10, and the other end of the intermediate connecting member 12 is connected to the second connecting member 11. The first connecting member 10 is connected to the first host connector 70, and the second connecting member 11 is connected to the second endoscope connector 80. The first connecting member 10, the second connecting member 11, and the intermediate connecting member 12 are detachably connected by bolts to facilitate the replacement of internal components.

[0050] The first connector 10 has a first sub-cavity 101, the second connector 11 has a second sub-cavity 111, and the intermediate connector 12 has a through cavity 121. The through cavity 121 communicates with both the first sub-cavity 101 and the second sub-cavity 111, thereby allowing the first end 20 to be disposed within the first sub-cavity 101, the second end 21 to be disposed within the second sub-cavity 111, and the conversion circuit board 22 to be disposed within the through cavity 121. This facilitates electrical connection between the first end 20 and the first host connector 70 when the first connector 10 is connected to the first host connector 70, and electrical connection between the second end 21 and the second endoscope connector 80 when the second connector 11 is connected to the second endoscope connector 80. It is understood that the first sub-cavity 101 extends through both ends of the first connector 10, the second sub-cavity 111 extends through both ends of the second connector 11, and the through cavity 121 extends through both ends of the intermediate connector 12.

[0051] The second connector 11 also has a mounting platform 112 extending into the second sub-cavity 111. A limiting member 4 is mounted on the mounting platform 112, and a connecting seat 3 is mounted on the limiting member 4. Multiple electrical contacts of the second end 21 are disposed on the connecting seat 3, which is electrically connected to the second endoscope connector 80. The limiting member 4 is used to limit the connection seat 3, preventing displacement or rotation and ensuring stability and reliability during electrical connection. Both the limiting member 4 and the connecting seat 3 are located within the second sub-cavity 111, and the shape of the connecting seat 3 is adapted to the second endoscope connector 80. The second end 21 is adapted to the electrical contacts on the second endoscope connector 80.

[0052] The intermediate connector 12 is provided with a pressing part 122, which is located inside the through cavity 121. One end face of the pressing part 122 presses against the end face of the connecting seat 3, and the outer end face of the intermediate connecting seat 3 presses against the limiting member 4. The mounting platform 112 of the first connector 10, intermediate connector 12, connecting seat 3, limiting member 4 and the second connector 11 are arranged in sequence, and are connected as a whole by bolts passing through the mounting platform 112 of the first connector 10, intermediate connector 12, connecting seat 3, limiting member 4 and the second connector 11.

[0053] A locking ring 5 is also provided at one end of the second connector 11 near the second endoscope connector 80. The locking ring 5 is circumferentially disposed in the second sub-cavity 111, and the outer wall of the locking ring 5 is engaged with the inner wall of the second connector 11. The locking ring 5 can move radially within the second sub-cavity 111. The outer wall of the second endoscope connector 80 has a locking groove 801, and the locking ring 5 is adapted to the locking groove 801. When it is necessary to connect the second endoscope connector 80 to the adapter, the second endoscope connector 80 is aligned with the second sub-cavity 111 of the second connector 11 and pressed together. The locking ring 5 is fastened in the locking groove 801 to achieve a locking connection.

[0054] A locking button 50 is also connected to the radial edge of the locking ring 5. The locking button 50 is locked on the second connector 11 and can move radially along the second sub-cavity 111. By pressing the locking button 50, the locking ring 5 can be pushed out of the locking groove 801, thereby unlocking and disengaging the adapter from the second endoscope connector 80.

[0055] A spring 51 is also provided between the locking button 50 and the second connector 11. One end of the spring 51 is fixed to the locking button 50, and the other end abuts against the wall of the second connector 11. The spring force of the spring 51 is along the radial direction of the locking ring 5. The spring 51 pushes the locking button 50 to spring back and reset.

[0056] A positioning retaining ring 6 is also provided at one end of the second connector 11 near the second endoscope connector 80. The positioning retaining ring 6 is used to limit the position of the locking ring 5 and prevent the locking ring 5 from falling out of the second sub-cavity 111. The locking ring 5 can only move radially and cannot be displaced axially. The positioning retaining ring 6 is connected to the second connector 11 by screws.

[0057] The adapter in this embodiment solves the problem of incompatibility between new / old main units and old / new endoscopes, avoiding equipment waste. It enables the connection and use of old main units with new endoscopes, or new main units with old endoscopes.

[0058] An embodiment of this utility model also provides an endoscope system, including: a first host 7, a second endoscope 8 and the aforementioned adapter. The first host 7 is provided with a first host connector 70, and the second endoscope 8 is provided with a second endoscope connector 80. The first end 20 of the adapter is electrically connected to the first host connector 70, and the second end 21 of the adapter is electrically connected to the second endoscope connector 80.

[0059] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
