[0002] In medical devices such as endoscopes, there are various interactions between the host and the endoscope or other detectors. These include electrical interactions—for example, the host provides power to the endoscope or other detectors; optical interactions—for example, the host provides a light source to the endoscope or other detectors and / or the endoscope or other detectors feed back the detected information to the host in the form of optical signals; and fluid interactions—for example, the host provides fluids such as water or air to the endoscope or other detectors, and so on.

[0003] Connectors, used to enable electrical, fluid, and optical connections between the host and the detector, typically include a socket with a cavity and a mating connector. The socket's cavity has an electrical connection portion, an optical connection portion, and a fluid connection portion; the mating connector has an electrical mating portion, an optical mating portion, and a fluid mating portion. Thus, when the connector is inserted into the socket's cavity, the electrical connection portion and the electrical mating portion connect to achieve an electrical connection, the optical interface and the optical connector connect to achieve an optical connection, and the fluid connection portion and the fluid mating portion connect to achieve a fluid connection.

[0037] The following will describe the present utility model in detail in conjunction with the specific embodiments shown in the drawings. However, these embodiments do not limit the present utility model, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these embodiments is included within the protection scope of the present utility model.

[0038] Refer Figure 1 and Figure 2 One embodiment of this utility model provides a medical device 100, which can specifically be an endoscope device.

[0039] The medical device 100 includes a main unit 10, an endoscope 20, and a connector 500.

[0040] The host 10 may include core components such as a light source, a controller and an image processor. The host 10 may also include a display screen 11 for displaying image information, a foot switch 13 for receiving user commands and a writing device 12 (e.g., a keyboard) for collecting information.

[0041] The connector 500 includes a socket 40 and a plug 30. The socket 40 is disposed on the host 10 or connected to the host 10 via a wiring harness, and the plug 30 is connected to the endoscope 20 via a conduit 21. Thus, the host 10 realizes various interactions with the endoscope 20 through the connector 500.

[0042] For example, the host 10 can electrically interact with the endoscope 20 through the connector 500. Specifically, the host 10 can supply power to the endoscope 20.

[0043] For example, the host 10 achieves optical interaction with the endoscope 20 through the connector 500. Specifically, the host 10 is equipped with a light source, which provides light to the endoscope 20 through the connector 500; and the endoscope 20 feeds back the detected image information to the host 10 in the form of an optical signal.

[0044] For example, the host 10 enables fluid interaction through the connector 500. Specifically, the host 10 can provide fluids such as water and air to the endoscope through the connector 500, and so on.

[0045] The function of connector 500 is not limited to this. For example, medical device 100 also includes water pump 80, water pipe 70, and suction pump 90. The main unit 10 is connected to the first interface 37 of connector 500 via water pipe 70 (see...). Figure 3 The main unit 10 supplies water to the endoscope 20 through the connector 500; the water pump 80 is connected to the second interface 38 of the connector 500 through a water pipe, thereby realizing the fluid communication between the water pump 80 and the endoscope 20; the suction pump 90 is connected to the third interface 39 of the connector 500 through a pipeline, thereby realizing the fluid communication between the suction pump 90 and the endoscope 20.

[0046] One embodiment of this application provides a connector 500 with improved structure to enhance the stability of optical, electrical, and fluid connections compared to existing connectors.

[0047] Specifically, refer to Figure 2 and Figure 3The connector 500 includes a plug 30 with a conduit 21 connected to its rear end and a socket 40 with a cavity 4.

[0048] As mentioned above, the connector 30 can be connected to the endoscope 20 via the conduit 21, which constitutes the docking terminal between the endoscope 20 and the external device; the socket 40 is fixedly mounted on the host 10 or connected to the host 10 via a wire harness, which constitutes the docking terminal of the host 10.

[0049] The connector 30 includes a plug portion 31 that is inserted into the cavity 4 and a housing 32 located between the connector 30 and the conduit 21.

[0050] The plug portion 31 includes a first base 311, a second base 312 protruding forward from the front end face 3110 of the first base, a first optical connection portion 341 that receives light from the socket 40, a second optical connection portion 342 that outputs light to the socket 40, a first fluid connection portion 343 that is in fluid communication with the socket 40, and a plurality of first electrical connection portions 344 that are electrically connected to the socket 40.

[0051] That is, when the plug 31 is inserted into the cavity 4 of the socket 40, the first optical connection 341 receives the light source provided by the host 10, the second optical connection 342 transmits the high-speed image signal from the endoscope 20 end to the host 10, and the first fluid connection 343 delivers gas or water to the inside of the endoscope 20 through the pipeline 21 to meet the requirements of flushing and ventilation.

[0052] Furthermore, a number of first electrical connection parts 344 are used for signal connection or power supply between the host 10 and the endoscope 20, and are preferably made of beryllium copper or metal material with gold plating.

[0053] Thus, by connecting the plug part 31 and the socket 40 cavity 4, the connection of the fiber optic end face, gas or liquid interface and electrical contact can be completed simultaneously.

[0054] The first base 311 and the second base 312 can be integrated as one unit or can be separate units that are fixedly assembled together; this application does not impose any restrictions on this.

[0055] The first optical connection part 341, the second optical connection part 342, and the first fluid connection part 343 are respectively disposed on the front end surface 3110 of the first base 311 and the front end surface 3120 of the second base 312.

[0056] The first electrical connection portions 344 may be specifically configured as PIN pin structures, but are not limited thereto. These first electrical connection portions 344 are arranged circumferentially on the outer peripheral surface of the first base 311.

[0057] Thus, in this embodiment, the connector 500 has a first optical connection portion 341, a second optical connection portion 342, and a first fluid connection portion 343 respectively disposed on either the front end face 3110 of the first base 311 or the front end face 3120 of the second base 312, and a first electrical connection portion 344 arranged circumferentially on the outer peripheral surface of the first base 311. This distribution structure enables simultaneous insertion and removal of optical, fluid, and electrical signals within a small radial range. When applied to the medical device 100, it can meet the requirements of high-quality image transmission, stable gas-liquid delivery, and reliable signal connection of the endoscope 20 during surgery or examination. It has the effects of simplifying the structure, improving positioning accuracy, and reducing processing difficulty.

[0058] In one embodiment, the first optical connection portion 341 and the first fluid connection portion 343 are respectively disposed on the front end face 3110 of the first base 311, and the second optical connection portion 342 is disposed on the front end face 3120 of the second base 312.

[0059] In this way, the first optical connection part 341 and the first fluid connection part 343 can simultaneously dock with the corresponding interface in the socket 40 when plugged in, so that the light source and gas-liquid delivery can be quickly plugged in and out at the same position. The second optical connection part 342 docks independently on the other front end face 3120, which helps to reduce mutual interference between different optical connections and optimize the signal transmission path, thereby further improving connection stability and image quality.

[0060] Furthermore, this arrangement, combined with the first electrical connection part 344 being set on the outer peripheral surface of the first base 311, not only effectively avoids the installation complexity and alignment difficulty caused by excessively dense layout of interfaces on the same end face, making the overall structure simpler, but also allows only the first electrical connection part 344 to be arranged on the outer peripheral surface of the plug part 31, avoiding problems such as poor contact and difficulty in docking caused by multiple interfaces being arranged on the outer peripheral surface. It can also reduce the processing accuracy requirements of the first electrical connection part 344, thereby maintaining good contact and signal transmission between the host 10 and the endoscope 20. In this way, while ensuring high-efficiency transmission of each channel, it further improves the overall operational reliability, service life and processing cost of the connector 500.

[0061] In this embodiment, the first base 311 and the second base 312 are configured as cylindrical structures and are concentrically arranged, that is, the central axis of the first base 311 and the central axis of the second base 312 are collinear.

[0062] For the convenience of description and understanding, the central axis of the connector 500 is defined by the straight line where the central axis of the first base 311 is located, and this central axis extends in the front-rear direction. Of course, in a variant embodiment, if the first base 311 is changed to other cylindrical shapes (i.e., non-cylindrical), a central axis can also be approximately defined along the extending direction of its cylindrical shape.

[0063] Regarding the specific structure of the first optical connection part 341, it may include an external soft shell and an optical fiber located inside, and may also include a sapphire bevel mirror at the front end. Thus, through the sapphire bevel mirror, the light emitted from the socket 40 to the first optical connection part 341 can be fully received, so as to improve the utilization rate of light.

[0064] Regarding the specific structure of the second optical connection part 342, it may also include an external soft shell and an optical fiber located inside, and may also include a glass plano lens at the front end.

[0065] In addition, in an embodiment, the first fluid connection part 343 can be used for gas circulation, for example, for transmitting the air flow provided by the host 10 to the endoscope 20. However, it is not limited thereto.

[0066] Refer Figure 3 and Figure 4 In one embodiment, the outer shell 32 is configured into a structure for the user to hold, so as to facilitate the user to plug the plug connector 30 into the socket 40.

[0067] The outer shell 32 is further configured with a first interface 37, a second interface 38 and a third interface 39. As described above, the first interface 37 can be connected to the host 10 through a water pipe, the second interface 38 is connected to the water pump 80, and the third interface 39 is connected to the suction pump 90; several tubes / wires are arranged inside the outer shell 32, such as the optical fiber extending backward from the first optical connection part 341, the optical fiber extending backward from the second optical connection part 34, the air pipe / water pipe extending backward from the first fluid connection part 343, the water pipe extending backward from the first interface 37, the pipeline extending backward from the second interface 38, and the pipeline extending backward from the third interface 39. These can all be arranged inside the outer shell 32 and integrated into a bundle and extend backward to the endoscope 20.

[0068] In an embodiment of the present application, the plug head 31 further includes a positioning ring 313 and a first circuit board 35.

[0069] The positioning ring 313 is assembled between the first base 311 and the outer shell 32. Specifically, the positioning ring 313 can be connected by any feasible method such as bonding, welding, riveting, screwing or buckling. Of course, in a variant embodiment, the positioning ring 313 can also be integrally formed with the first base 313 or integrally provided with the outer shell 32.

[0070] The first circuit board 35 is fixedly assembled on the inner side of the first base 311 or the positioning ring 313; a plurality of first electrical connection parts 344 are configured as a plurality of conductive sheets (e.g., PIN pins), one end of the conductive sheet is located at the circuit board 35 and electrically connected to the circuit board 35, and the other end is located on the outer peripheral surface of the first base 311.

[0071] In one embodiment, the positioning ring 313 is also used to cooperate with the socket 40 to achieve axial (i.e. front-to-back) positioning when the plug 30 is inserted into the cavity 4 of the socket 40 from back to front.

[0072] Specifically, the plug portion 31 also has a guide surface 3131 and a positioning groove 3132 sequentially arranged behind the first base 311. In this embodiment, the guide surface 3131 and the positioning groove 3132 are formed on the positioning ring 313. The guide surface 3131 expands outward from front to back.

[0073] Correspondingly, participants Figures 5 to 7 The socket 40 has an outer seat 411, a positioning spring 45, and a positioning bead 46. The outer seat 411 has a tapered groove 4112 that tapers from the outside to the inside and communicates with the cavity 4. The positioning bead 46 is accommodated in the tapered groove 4112 and partially protrudes into the cavity 4. The positioning spring 45 is connected to the outer seat 411 and presses the positioning bead 46 inward.

[0074] During the insertion of the plug portion 31 into the cavity 4, the positioning bead 46, pushed by the guide surface 3131, overcomes the elastic force of the positioning spring 45 and moves outward, that is, away from the central axis of the cavity 4. After passing the guide surface 3131, the positioning bead 46, driven by the elastic restoring force of the positioning spring 45, moves inward and penetrates into the cavity 4 to embed into the positioning groove 3132. This structure enables automatic locking and accurate positioning during insertion and removal, ensuring that the plug portion 31 remains stably engaged within the socket 40, preventing the plug portion 31 from becoming loose or misaligned, thereby ensuring continuous and reliable transmission of optical, fluid, and electrical signals between the endoscope 20 and the main unit 10.

[0075] In one embodiment, a plurality of positioning beads 46 are provided, which are divided into multiple groups evenly distributed around the circumference of the socket 40. For example, in the embodiment shown in the figure, there are two groups of positioning beads 46, each group containing 4 positioning beads 46, and the two groups of positioning beads 46 are arranged radially symmetrically. The number of tapered grooves 412 and the number of positioning spring pieces 45 are the same as the number of positioning beads 46 and their positions correspond one-to-one.

[0076] Among them, the multiple positioning springs 45 corresponding to the positioning beads 46 in the same group can be set as follows: the fixed end (i.e. the end that is fixedly connected to the outer base 411) is integrally set, and the free end (i.e. the end that abuts against the positioning beads 46) is set, which can facilitate installation.

[0077] Next, participants Figure 2 and Figure 5 The connector 30 also has a guide block 36 disposed on the outer periphery of the plug portion 31. Correspondingly, the socket 40 also has a guide groove 4111 communicating with the cavity 4. When the plug portion 31 is inserted into the cavity 4 of the socket 40 from back to front, the guide block 36 can move axially along the guide groove 4111, thereby achieving the guiding function during insertion and enhancing the connection stability.

[0078] Next, continue to refer to Figures 5 to 7 The socket 40 has a third optical connection portion 441, a fourth optical connection portion 443, and a second fluid connection portion 444 that communicate with the cavity 4.

[0079] When the plug 31 is inserted into the cavity 4 of the socket 40: the first optical connection 341 mates with the third optical connection 441 to receive light from the socket 40 so that the host 10 can provide a light source to the endoscope 20; the second optical connection 342 mates with the fourth optical connection 443 to output light to the socket 40 so that the image information detected by the endoscope 20 is fed back to the host 10 in the form of light; the first fluid connection 343 mates with the second fluid connection 444.

[0080] By cleverly distributing different optical and fluid connectors on the front surfaces of the first base 311 and the second base 312, mutual interference between optical and fluid channels can be effectively reduced when the connector 30 is inserted into the socket 40, facilitating accurate guidance and stable coupling of light and gas / liquid. At the same time, several first electrical connectors 344 are evenly arranged on the outer peripheral surface of the first base 311, which can maintain good contact and signal transmission between the host 10 and the endoscope 20, thereby further improving the overall operational reliability and service life of the connector 500 while ensuring high-efficiency transmission of each channel.

[0081] In one embodiment, the first optical connector 341 is configured as a tube structure, and the third optical connector 441 has a hole structure, enabling them to be inserted and connected. Of course, this application is not limited to this.

[0082] Similarly, the second optical connector 342 is configured as a tube structure, and the fourth optical connector 443 has a hole structure, enabling them to be inserted and connected. Of course, this application is not limited to this.

[0083] Similarly, the first fluid connection part 343 is configured as a pipe structure, and the second fluid connection part 444 has a hole structure, so that the two can be inserted and connected. Of course, this application is not limited to this.

[0084] Furthermore, the socket 40 also includes a heat sink 47 located at least partially in front of the cavity 4, the heat sink 47 being in contact with the front end of the first optical connection portion 341, and the heat sink 47 having a plurality of heat dissipation fins 471 extending outward around the first optical connection portion 341.

[0085] Thus, by arranging the heat sink 47 at the front of the cavity 4 and tightly coupling it with the first optical connection part 341, the residual heat generated by the light source of the host 10 can be removed in time, avoiding overheating during insertion and removal, which could lead to burns or performance degradation. The heat sink fins 471 are distributed circumferentially to increase the heat dissipation area, which can further improve the overall heat dissipation efficiency and maintain the stability of optical transmission, so that the connector 500 has both safety and high efficiency when the endoscope 20 is used in conjunction with the host 10.

[0086] In addition, Figures 5 to 9 The socket 40 also includes a support base 41 and a U-shaped light shield 48.

[0087] Specifically, the support base 41 forms the support frame for the other components of the socket 40. When the plug 30 and the socket 40 are plugged in, the support base 41 is fixed relative to the plug 30.

[0088] The support base 41 includes the outer base body 411 and the bracket part 413 mentioned above. The bracket part 413 and the outer base body 413 are fixedly arranged and can be directly connected or indirectly connected.

[0089] The U-shaped light-shielding member 48 is movably connected to the bracket portion 413 of the support base 41, and has a shielding position and a release position relative to the bracket portion 413. In the shielding position, the light-shielding member 48 is located on the light emission path behind the third light connection portion 441, for example, in the channel 4110 behind the third light connection portion 441, so as to block the light from emanating from the third light connection portion 441 out of the cavity 4; in the release position, the light-shielding member 48 exits the light emission path behind the third light connection portion 441, for example, exiting the channel 4110.

[0090] When the first optical connector 341 moves forward to engage with the third optical connector 441, the light-shielding member 48 moves from the shielding position to the release position under the push of the first optical connector 341.

[0091] Thus, through this light-shielding design, the high-brightness light can be effectively blocked from leaking out before the plug part 31 is inserted, preventing irritation to the operator. When the first optical connection part 341 is inserted, the shielding is automatically released and the optical fiber coupling is completed, realizing reliable docking between the light source and the endoscope 20.

[0092] In one embodiment, the light-shielding member 48 is rotatably connected to the support base 41 to change between a shielded position and a released position. For example, in one embodiment, the upper end of the light-shielding member 48 is rotatably connected to the support base 41, and in the shielded position, the lower end of the light-shielding member 48 enters the light emission path behind the third light connection portion 441; thus, when the first light connection portion 341 exits the cavity 4, the light-shielding member 48 remains in the shielded position under its own weight. Alternatively, in another variation embodiment, the socket 40 further includes a reset elastic member disposed between the support base 41 and the light-shielding member 48, so that when the first light connection portion 341 exits the cavity 4, the light-shielding member 48 remains in the shielded position under the action of the reset elastic member.

[0093] By using its own weight or the action of an elastic element, the light-shielding member 48 automatically returns to the shielding position. When the first light connection part 341 is completely disengaged from the socket 40, the high-brightness light source is blocked again, and the operating environment can be continuously protected. At the same time, the structure is simple and highly reliable.

[0094] Furthermore, in one embodiment, the socket 40 further includes a cylindrical socket clip 42, which is provided with a plurality of second electrical connection portions 442, the number and position of which correspond one-to-one with the plurality of first electrical connection portions 344. In the plugged-in state, the plurality of second electrical connection portions 442 contact and are electrically connected to the plurality of first electrical connection portions 344.

[0095] Preferably, the socket clip 42 is movably fitted onto the outer periphery of the first base 311 in a radial direction perpendicular to the front-back direction. That is, when the plug 30 is inserted into the socket 40, the socket clip 42 is fitted onto the outside of the first base 311 and can float radially relative to the first base 311.

[0096] In this way, by combining the first electrical connection part 344 set on the outer periphery of the first base 311 and the second electrical connection part 442 set on the socket clip 42 corresponding to the first electrical connection part 344, and by enabling the socket clip 42 to be adaptively fine-tuned in the radial direction, the reliability of electrical contact between the plug 30 and the socket 40 is further improved, avoiding poor contact or signal transmission loss due to manufacturing and assembly tolerances; at the same time, excessive wear during the insertion and removal process can be reduced, thereby ensuring long-term stable transmission of electrical signals between the endoscope 20 and the host 10, and extending the overall service life of the connector 500.

[0097] Specifically, in one embodiment, the support base 41 is configured to be sleeved with the socket clip 42 and radially spaced from each other, that is, the socket clip 42 has a certain gap with the support base 41 in the radial direction.

[0098] The socket 40 also includes a plurality of supporting elastic members 43. These supporting elastic members 43 are fixedly connected to the support base 41 and are arranged circumferentially around the socket clamp 42; and the free end of each supporting elastic member 43 radially abuts against the socket clamp 42. Thus, supported by the plurality of supporting elastic members 43, the socket clamp 42 is radially and relatively movably engaged with the support base 41.

[0099] In this way, by setting a support elastic element 43 between the support base 41 and the socket clamp 42, the socket clamp 42 is supported by the support elastic element 43, which allows the socket clamp 42 to be set radially wobbly. This enables the socket clamp 42 to be adaptively fine-tuned in the radial direction, further improving the reliability of electrical contact between the connector 30 and the socket 40, avoiding poor contact or signal transmission loss due to manufacturing and assembly tolerances. At the same time, it can reduce excessive wear during the insertion and removal process, thereby ensuring long-term stable transmission of electrical signals between the endoscope 20 and the host 10, and extending the overall service life of the connector 500.

[0100] For example, the front end of the supporting elastic member 43 is fixedly connected to the support base 41, and the rear end forms its free end and radially abuts against the socket clamp 42. Of course, the reverse is also possible.

[0101] In one embodiment, the plurality of supporting elastic members 43 may be divided into two, three, four or more groups and evenly arranged around the socket clamp 42 in the circumference, or the plurality of supporting elastic members 43 may be evenly arranged around the socket clamp 42 in the circumference. These methods can improve the positional stability of the socket clamp 42.

[0102] For example, in the embodiment shown in the figure, the socket 40 has a total of three sets of supporting elastic members 43, which are arranged at a central angle of 120°. This application is not limited thereto.

[0103] The number of each set of support elastic elements 43 can be one support elastic element 43, or it can be two or more support elastic elements 43 that are separately or integrally set. In the case of integral setting, the fixed ends (i.e. the ends that are fixedly connected to the support base 41) of two or more support elastic elements 43 can be integrally connected, and their free ends can be separated from each other.

[0104] Furthermore, the socket clip 42 can also be configured to movably engage with the support base 41 in the front-to-back direction. That is, the socket clip 42 can not only float radially, but also move back and forth. This can further improve the self-adaptive fine-tuning of the socket clip 42 in position, further enhance the reliability of electrical contact between the connector 30 and the socket 40, and avoid poor contact or signal transmission loss due to manufacturing and assembly tolerances; at the same time, it can reduce excessive wear during the insertion and removal process, thereby ensuring long-term stable transmission of electrical signals between the endoscope 20 and the host 10, and extending the overall service life of the connector 500.

[0105] In one embodiment, the support base 41 includes an outer base body 411 and an inner base body 412. The inner base body 412 is fixedly connected to the outer base body 411, for example, by means of screws 415 or other fastening structures, or by means of integral molding.

[0106] The outer seat 411 is sleeved on the outside of the socket clamp 42, and the inner seat 412 is nested inside the front part of the socket clamp 42. Both the outer seat 411 and the inner seat 412 are radially spaced from the socket clamp 42.

[0107] The outer seat 411 has a first stepped surface 4113 located behind at least a portion of the socket clamp 42, and the inner seat 412 has a second stepped surface 4124 located in front of at least a portion of the socket clamp 42. The fore-and-aft travel of the socket clamp 42 relative to the support 41 is defined by the first stepped surface 4113 and the second stepped surface 4124.

[0108] That is, when the socket clamp 42 moves backward axially to abut against the first step surface 4113, the end point of the backward travel of the socket clamp 42 is defined. Understandably, at this time, the socket clamp 42 does not contact the second step surface 4124. Conversely, when the socket clamp 42 moves forward axially to abut against the second step surface 4124, the end point of the forward travel of the socket clamp 42 is defined. Understandably, at this time, the socket clamp 42 does not contact the first step surface 4113.

[0109] This configuration ensures that the socket clamp 42 can make limited adaptive floating in the radial direction, while also allowing it to move appropriately in the front and back directions. This allows the socket clamp 42 to compensate for manufacturing and assembly errors in a timely manner during insertion and removal, thereby further maintaining the high-precision alignment between the socket 40 and the connector 30 and enhancing the connection reliability. It also makes the signal or optical path between the endoscope 20 and the host 10 more stable, and improves the service life and overall performance of the connector 500.

[0110] Preferably, the socket clip 42 has a circumferentially extending groove 423, and the free ends of a plurality of supporting elastic members 43 abut against the groove 423. This allows for a more stable positional relationship through the cooperation of the supporting elastic members 43 and the groove 423.

[0111] In addition, when the free end of the supporting elastic member 43 abuts against the groove 423, there are gaps between the socket clamp 42 and the first step surface 4113, and between the socket clamp 42 and the second step surface 4124, thereby ensuring the degree of freedom of the socket clamp 42 in radial floating and avoiding excessive resistance.

[0112] In the embodiment shown in the accompanying drawings, a plurality of supporting elastic members 43 are arranged circumferentially on the inner side of the outer seat 411, and their free ends abut against the outer wall of the socket clamp 42 radially inward. Correspondingly, the groove 423 is located on the outer peripheral wall of the socket clamp 42. However, this application is not limited to this. For example, in a variant embodiment, a plurality of supporting elastic members 43 may also be arranged circumferentially on the outer side of the inner seat 412, and their free ends abut against the inner wall of the socket clamp 42 radially outward. Correspondingly, the groove 423 is located on the outer peripheral wall of the socket clamp 42. This can also achieve the floating effect of the socket clamp 42.

[0113] In another embodiment, the socket 40 also includes a second circuit board 49 located in front of the socket clip 42, and one end of a plurality of second electrical connection portions 442 extends forward to the second circuit board 49 and is electrically connected to the second circuit board 49.

[0114] The second circuit board 49 is fixedly or movably connected to the socket clamp 42 and moves synchronously with the socket clamp 42 relative to the support base 41. In this way, the electrical connection stability of the second electrical connection part 442 can be improved, and poor electrical connection caused by the floating of the socket clamp 42 can be avoided; and the service life of the second electrical connection part 442 can also be extended.

[0115] Specifically, the second circuit board 49 can be fixedly connected by a screw 491 and a threaded connection between the screw 491 and the threaded hole 421 of the socket clip 42; as mentioned above, this application is not limited thereto.

[0116] In this application, the second electrical connection part 442 is configured as a PIN pin, preferably made of a highly conductive material such as beryllium copper and subjected to plating treatment.

[0117] In summary, compared with the prior art, this embodiment has the following beneficial effects: by disposing the first optical connection part 341, the second optical connection part 342, and the first fluid connection part 343 on either the front end face 3110 of the first base 311 or the front end face 3120 of the second base 312, and arranging the first electrical connection part 344 circumferentially on the outer peripheral surface of the first base 311, this distribution structure can simultaneously realize the plug-in connection of optical, fluid, and electrical signals within a small radial range. When applied to the medical device 100, it can meet the requirements of high-quality image transmission, stable gas-liquid delivery, and reliable signal connection of the endoscope 20 during surgery or examination, and has the effects of simplifying the structure, improving positioning accuracy, and reducing processing difficulty.

All equivalent implementation methods or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
