[0033] Ginseng Figures 1 to 8 A specific embodiment of an optoelectronic connection component for connecting an optical imaging system and a handheld terminal disclosed in the present invention is different from the existing problem that a plurality of connection lines are required between the handle of an endoscope and the device end for respectively connecting the lighting source, transmitting optoelectronic signals and connecting the power supply, which results in the need for multiple wiring before and during the operation, thus affecting the normal operation. By connecting to the output terminal 2 of the device end 3 and the connection terminal 1 connected to the output terminal 2 and connected to the endoscope handle 31 through a bus 32, the problem of multiple wiring required before and during the operation due to entanglement of multiple connection lines is avoided, so as to facilitate the smooth operation.

After the optical signal after imaging by the endoscope handle 31 is converted twice from light to electricity and from electricity to light, it is transmitted back to the device end 3 through the transmission line 121.

Specifically, the optical fiber connector 11 is selected as a wolf optical fiber connector.

[0035] Existing endoscopes usually have multiple device ends, which are used for lighting, photoelectric signal conversion, and power supply respectively. Existing multiple device ends are usually placed in order from top to bottom, and each device end has an interface. Each interface is connected to the endoscope handle through a signal line, which leads to the problem of messy wiring between the existing endoscope and the device end. Multiple wiring needs to be sorted multiple times before and during the operation, which affects the normal operation to a certain extent. In this embodiment, the connection end 1 integrates the optical fiber connector 11 and the electrical signal connector 12. Through the single docking of the connection end 1 and the output end 2, the optical transmission of the optical fiber 111, the optical signal transmission of the transmission line 121, and the power supply of the endoscope handle 31 by the power signal line 122 and the ground signal line 123 are simultaneously realized, and the above lines are aggregated to the bus 32 and connected to the endoscope handle 31 through a bus 32, avoiding the problem of difficult wiring caused by connecting multiple lines between the existing multiple device ends and the endoscope handle. Furthermore, in this embodiment, modules with various functions are arranged in the device end 3, and when the connection end 1 and the output end 2 are connected, each module is connected, which further improves the convenience of using the device.

The upper shell 14 and the lower shell 13 are buckled with each other in the vertical direction. After the upper shell 14 and the lower shell 13 are connected to each other, an opening is formed at one end in the horizontal direction, and the other end is for the bus 32 to pass through. The sleeve 15 covers the opening and allows the optical fiber connector 11 and the electrical signal connector 12 fixed to the opening to pass through; the end cover 16 is connected to the side of the sleeve 15 away from the opening. When the connection end 1 is connected to the output end 2, the optical fiber connector 11 passes through the end cover 16 and connects with the illumination light source 22. After the electrical signal connector 12 passes through the end cover 16, the endoscope handle 31 transmits the optical signal to the device end and turns on the power.

[0038] Ginseng Figures 3 to 7As shown, the output terminal 2 includes a base 23 and a facade 24. The base 23 is fixed inside the device terminal 3. The bottom plate 33 is fixed inside the device terminal 3. The bottom plate 33 is attached to and fixed to the inner wall of the device terminal 3. The base 23 is fixed to the upper surface of the bottom plate 33. The bottom wall of the facade 24 is vertically fixed to the upper surface of the base 23 and passes through the side wall of the device terminal 3. The plug-in terminal 21 is connected to the side of the facade 24 located inside the device terminal 3, and the notch of the slot 211 of the plug-in terminal 21 is flush with the side of the facade 24 located outside the device terminal 3; the bottom surface of the illumination light source 22 is vertically fixed to the upper surface of the base 23. Two support seats 29 are symmetrically distributed on the base 23. The bottom surface of the support seat 29 is attached to and fixed to the upper surface of the base 23, and the side walls of the two support seats 29 in the height direction are attached to and fixed to the side walls of the facade 24 respectively. Specifically, the shape of the base plate 33 is consistent with the cross-sectional shape of the device end 3. The base plate 33 is fixedly connected to the device end 3. The optical signal input interface, power module and ground interface in the device end 3 are arranged on the base plate 33 (not shown) so as to be connected with the transmission line 121, power signal line 122 and ground signal line 123 arranged in the electrical signal connector 12.

[0039] Ginseng Figures 3 to 8 As shown, the light emitting area 221 of the illumination light source 22 is inserted into the plug end 21, and after the sleeve 15 and the end cover 16 are inserted into the slot 211, the optical fiber connector 11 is connected to the light emitting area 221 of the illumination light source 22, and the plug end 21 has a first positioning column 212 that passes through the end cover 16 and the sleeve 15. The vertical surface 24 is located on both sides of the length direction of the plug end 21 and is respectively provided with a positioning device 25, the positioning device 25 includes a positioning block 251 and a ball plunger 252, and the end cover 16 forms a positioning groove 161 adapted to the two ball plungers 252. When the connection end 1 and the plug end 21 are in a docking state, the two ball plungers 252 pass through the plug end 21 and are respectively embedded in a positioning groove 161. The outer wall of the sleeve 15 is formed with a taper, and the width and height of the end of the sleeve 15 connected to the opening are greater than the width and height of the end connected to the end cover 16. When the sleeve 15 is inserted into the slot 211, a gap is formed between the taper of the outer wall and the slot wall of the slot 211. The top surface of the end cover 16 is integrally formed with an anti-idiot block 162, and the slot 211 forms an anti-idiot groove 2111 adapted to the anti-idiot block 162.

[0040] When the connection end 1 is connected to the output end 2, the end cover 16 is first aligned with the slot 211. In the process of connecting the connection end 1 and the output end 2, the sleeve 15 and the end cover 16 move together into the slot 211 until the anti-idiot block 162 formed on the top surface of the end cover 16 is embedded in the anti-idiot groove 2111 formed on the slot wall of the slot 211. At this time, the first positioning column 212 passing through the bottom of the slot 211 of the plug end 21 extends into the positioning hole (not marked, the specific state is referenced) opened in the connection between the end cover 16 and the sleeve 15. Figure 7 and Figure 8As shown in the figure), the ball plungers 252 arranged on both sides of the plug end 21 are respectively embedded in a positioning groove 161 opened on the side wall of the end cover 16. At this time, the optical fiber connector 11 reaches the docking position with the light-emitting area 221 of the illumination light source 22, and the transmission line 121, the power signal line 122 and the ground signal line 123 of the electrical signal connector 12 respectively reach the docking position with the corresponding connectors of each module in the device end 3, so that the endoscope handle 31 can be held for surgical examination. It should be noted that in this embodiment, by forming a taper on each side wall of the sleeve 15, there is always a gap between the side walls of the sleeve 15 and the groove walls of the slot 211 during the process of the sleeve 15 moving into the slot 211 until it is installed in place (refer to the figure). Figure 8 As shown), so that the connection end 1 as a whole can be smoothly connected with the slot 211. Further, as Figure 4 , Figure 6 as well as Figure 7 As shown, the light emitting area 221 of the illumination light source 22 is an annular protrusion, and when the connection end 1 is docked in place in the slot 211, the optical fiber connector 11 passes through the plug end 21 and is embedded in the annular channel (not marked) of the light emitting area 221. Through the above design, the first positioning column 212 facilitates the connection alignment between the connection end 1 and the output end 2, and the two ball head plungers 252 are used to limit the entirety of the installed connection end 1 to prevent it from falling out of the slot 211, and the anti-fool block 162 cooperates with the anti-fool groove 2111 to prevent the connection end 1 from getting stuck in the slot 211.

Since the illumination light source 22 generates a large amount of heat when emitting light, the cooling device 26 attached to the illumination light source 22 can absorb the heat emitted by the illumination light source 22 to achieve effective cooling of the illumination light source 22, so as to avoid the imaging and operation of the endoscope being affected by local overheating. It should be noted that the bracket 27 installing the cooling device 26 can not only cool the lighting source 22 but also clamp the lighting source 22 between the cooling device 26 and the plug-in end 21 , thereby effectively positioning the lighting source 22 .
