[0049] The present utility model will be described in detail below in conjunction with the specific embodiments shown in the accompanying 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.

[0050] Refer Figure 1 and Figure 2 , an embodiment of the present utility model provides a medical device 100, which may specifically be an endoscope device.

[0051] The medical device 100 includes a main unit 10, an endoscope 20, and a connector 500.

[0052] The main unit 10 may include core components such as a light source, a controller, and an image processor. The main unit 10 may also be attached with a display screen 11 for displaying image information, a foot switch 13 for receiving user instructions, and a writing device 12 (such as a keyboard) for collecting information.

[0053] The connector 500 includes a socket 40 and a plug connector 30. The socket 40 is disposed on the main unit 10 or connected to the main unit 10 through a wire harness. The plug connector 30 is connected to the endoscope 20 through a pipeline 21. Thus, the main unit 10 realizes various interactions with the endoscope 20 through the connector 500.

[0054] For example, the main unit 10 realizes electrical interaction with the endoscope 20 through the connector 500. Specifically, the main unit 10 can supply power to the endoscope 20.

[0055] For another example, the main unit 10 realizes optical interaction with the endoscope 20 through the connector 500. Specifically: a light source is configured inside the main unit 10, which provides light to the endoscope 20 through the connector 500; and the endoscope 20 feeds back the detected image information to the main unit 10 in the form of an optical signal.

[0056] For yet another example, the main unit 10 realizes fluid interaction through the connector 500. Specifically, the main unit 10 can provide fluids such as water and gas to the endoscope through the connector 500, and so on.

[0057] The function of the connector 500 is not limited to this. For example, the medical device 100 further includes a water pump 80, a water pipe 70, and a suction pump 90. The main unit 10 is connected to the first interface 37 of the connector 500 through the water pipe 70 (see Figure 3), the host 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, so as to realize 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 pipe, so as to realize the fluid communication between the suction pump 90 and the endoscope 20.

[0058] In an embodiment of the present application, the connector 500 is provided with an improved structure to solve the problems of low connection precision and serious wear in the prior art.

[0059] Specifically, referring to Figure 2 The connector 500 includes a plug 30 connected with the pipeline 21 at the rear end and a socket 40 provided with a concave cavity 4.

[0060] As described above, the plug 30 can be connected with the endoscope 20 through the pipeline 21, and constitutes a docking terminal between the endoscope 20 and external equipment; the socket 40 is fixedly arranged on the host 10 or connected with the host 10 through a wire harness, and constitutes a docking terminal of the host 10.

[0061] The plug 30 includes a plug portion 31 inserted into the concave cavity 4 from the rear to the front, and a plurality of first electrical connection portions 344 arranged on the outer periphery of the plug portion 31. In this way, the plug portion 30 is inserted into the concave cavity 4, so as to realize the docking of the plug 30 and the socket 40.

[0062] Next, referring to Figures 3 to 7 The socket 40 further includes a socket clamp 42 in the shape of a cylinder, and the socket clamp 42 is provided with a plurality of second electrical connection portions 442 corresponding to the number and positions of the first electrical connection portions 344 in one-to-one correspondence. In the plugged state, the plurality of second electrical connection portions 442 are in contact with and electrically connected with the plurality of first electrical connection portions 344.

[0063] Preferably, the socket clamp 42 is relatively movably sleeved on the outer periphery of the plug portion 31 in the radial direction perpendicular to the front-rear direction, that is, when the plug 30 is inserted into the socket 40, the socket clamp 42 is sleeved on the outside of the plug portion 31 and can float radially relative to the plug portion 31.

[0064] In this way, in the case that the first electrical connection portions 344 are arranged on the outer periphery of the plug portion 31 and the second electrical connection portions 442 corresponding to the first electrical connection portions 344 are arranged on the socket clamp 42, further self-adapting fine adjustment of the socket clamp 42 in the radial direction can further improve the electrical contact reliability between the plug 30 and the socket 40, avoid poor contact or signal transmission loss caused by manufacturing and assembly tolerances, and at the same time can reduce excessive wear in the plugging process, so as to ensure long-term stable transmission of electrical signals between the endoscope 20 and the host 10, and prolong the overall service life of the connector 500.

[0065] Further, the socket 40 comprises a support seat 41 and a plurality of support elastic members 43.

[0066] The support seat 41 is arranged to be sleeved with the socket clamps 42 and radially spaced from each other, that is, the socket clamps 42 have a certain gap with the support seat 41 in the radial direction.

[0067] The support elastic members 43 are arranged in the circumferential direction of the socket clamps 42, and one end (i.e. the fixed end) is fixedly connected to the support seat 41, and the other end (i.e. the free end) radially abuts against the socket clamps 42. In this way, the socket clamps 42 are relatively movably connected to the support seat 41 in the radial direction under the support of the plurality of support elastic members 43.

[0068] In this way, by arranging the support elastic members 43 between the support seat 41 and the socket clamps 42, the support of the socket clamps 42 is realized by the support elastic members 43, so that the socket clamps 42 can be arranged to be radially movable, the socket clamps 42 can be self-adaptively fine-tuned in the radial direction, the electrical contact reliability between the plug-in connector 30 and the socket 40 is further improved, and the contact failure or signal transmission loss caused by manufacturing and assembly tolerances is avoided; at the same time, excessive wear during plugging and unplugging can be reduced, so that the long-term stable transmission of electrical signals between the endoscope 20 and the main machine 10 is ensured, and the overall service life of the connector 500 is prolonged.

[0069] For the convenience of understanding and description, in the present application, the front-rear direction, i.e. the axial direction, is defined by the plugging direction of the plug-in connector 30, that is, the direction in which the plug-in connector 30 is inserted into the cavity 4 is defined as "front", and conversely, the direction in which the plug-in connector 30 is pulled out of the cavity 4 is defined as "rear".

[0070] In an embodiment, the front end of the support elastic member 43 is fixedly connected to the support seat 41 to constitute the fixed end thereof, and the rear end constitutes the free end thereof and radially abuts against the socket clamp 42. Of course, the reverse is also possible.

[0071] In an embodiment, the plurality of support elastic members 43 can be divided into two groups, three groups, four groups or more groups and arranged uniformly in the circumferential direction of the socket clamps 42, or the plurality of support elastic members 43 are uniformly arranged around the socket clamps 42 in the circumferential direction, and in this way, the positional stability of the socket clamps 42 can be improved.

[0072] For example, in the embodiment shown in the figure, the socket 40 has a total of three groups of support elastic members 43, and the three groups of support elastic members 43 are arranged at a central angle of 120°. The present application is not limited thereto.

[0073] The number of support elastic members 43 in each group can include one support elastic member 43, or can include two or more support elastic members 43 arranged separately or integrally, and in the case of integral arrangement, the fixed ends (i.e. the end fixedly connected to the support seat 41) of the two or more support elastic members 43 can be integrally connected, and the free ends thereof are separated from each other.

[0074] Further, the socket clamp 42 can also be arranged to be relatively movably connected to the support base 41 in the front-rear direction. That is, the socket clamp 42 can not only float in the radial direction, but also move in the front-rear direction. In this way, the self-adaptive fine adjustment of the position of the socket clamp 42 can be further improved, and the socket clamp 42 can avoid excessive friction resistance when floating in the radial direction, further improving the electrical contact reliability between the plug connector 30 and the socket 40, avoiding poor contact or signal transmission loss due to manufacturing and assembly tolerances; at the same time, excessive wear during plugging and unplugging can be reduced, thereby ensuring long-term stable transmission of electrical signals between the endoscope 20 and the main machine 10, and prolonging the overall service life of the connector 500.

[0075] In an embodiment, the support base 41 includes an outer base body 411 and an inner base body 412, and the inner base body 412 is fixedly connected to the outer base body 411, for example, by screws 415 or other fastening structures, or by an integral molding method.

[0076] The outer base body 411 is arranged on the outer side of the socket clamp 42, and the inner base body 412 is nested on the inner side of the front part of the socket clamp 42, and the outer base body 411 and the inner base body 412 are both arranged in the radial direction and spaced apart from the socket clamp 42.

[0077] The outer base body 411 has a first step surface 4113 located at least partially behind the socket clamp 42, and the inner base body 412 has a second step surface 4124 located at least partially in front of the socket clamp 42. The front-rear movement stroke of the socket clamp 42 relative to the support base 41 is defined by the first step surface 4113 and the second step surface 4124.

[0078] That is, when the socket clamp 42 moves axially backward to abut against the first step surface 4113, the rear stroke end of the socket clamp 42 is defined. It can be understood that at this time, the socket clamp 42 does not contact the second step surface 4124. Conversely, when the socket clamp 42 moves axially forward to abut against the second step surface 4124, the front stroke end of the socket clamp 42 is defined. It can be understood that at this time, the socket clamp 42 does not contact the first step surface 4113.

[0079] In this way, the socket clamp 42 can be allowed to move in the front-rear direction while floating in the radial direction, so that the socket clamp 42 can compensate for manufacturing and assembly errors in time during the plugging and unplugging process, thereby further maintaining the high-precision alignment of the socket 40 and the plug connector 30 and enhancing the connection reliability, making the signal or optical path between the endoscope 20 and the main machine 10 more stable, and improving the service life and overall performance of the connector 500.

[0080] Preferably, the socket clamp 42 has a circumferentially extending groove 423, and the free ends of the plurality of supporting elastic members 43 abut in the groove 423. In this way, a more stable positional relationship can be achieved by the cooperation of the supporting elastic members 43 and the groove 423.

[0081] In addition, when the free ends of the supporting elastic members 43 abut in the groove 423, there is a gap 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 freedom of the socket clamp 42 in radial floating and avoiding excessive resistance.

[0082] In the embodiment of the drawings, the plurality of supporting elastic members 43 are circumferentially arranged on the inner side of the outer seat body 411, and the free ends abut the outer wall of the socket clamp 42 radially inward, and correspondingly, the groove 423 is located on the outer peripheral wall of the socket clamp 42. However, the present application is not limited thereto, for example, in a variant embodiment, the plurality of supporting elastic members 43 can also be circumferentially arranged on the outer side of the inner seat body 412, and the free ends abut the inner wall of the socket clamp 42 radially outward, and correspondingly, the groove 423 is located on the outer peripheral wall of the socket clamp 42, so that the floating effect of the socket clamp 42 can also be achieved.

[0083] In addition, in an embodiment, the socket 40 further comprises a second circuit board 49 located in front of the socket clamp 42, and one end of the plurality of second electrical connection portions 442 extends forward to the second circuit board 49 and is electrically connected with the second circuit board 49.

[0084] 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 seat 41. In this way, the electrical connection stability of the second electrical connection portion 442 can be improved, and poor electrical connection caused by floating of the socket clamp 42 can be avoided, and the service life of the second electrical connection portion 442 can also be improved.

[0085] Specifically, the second circuit board 49 can be fixedly connected by screw thread connection between the screw 491 and the threaded hole 421 of the socket clamp 42, but the present application is not limited thereto.

[0086] In the present application, the first electrical connection portion 344 and the second electrical connection portion 442 are provided as PIN pins, and preferably made of high-conductivity materials such as beryllium copper and subjected to plating treatment.

[0087] Further, referring to Figures 7 to 9 The outer periphery of the plug portion 31 further has a guide surface 3131 and a positioning groove 3132 arranged in sequence from front to back, and the guide surface 3131 expands outward from front to back.

[0088] Correspondingly, the socket 40 has an outer seat body 411, positioning elastic sheets 45 and positioning beads 46. The outer seat body 411 is provided with a tapered slot 4112 which is tapered from outside to inside and communicates with the recess 4, the positioning beads 46 are accommodated in the tapered slot 4112 and partially protrude into the recess 4, and the positioning elastic sheets 45 are connected to the outer seat body 411 and press the positioning beads 46 inward.

[0089] During the process of inserting the plug head 31 into the recess 4, the positioning beads 46 are driven by the guide surface 3131 to move outward, i.e. move away from the central axis of the recess 4, against the elastic force of the positioning elastic sheets 45; and after passing the guide surface 3131, the positioning beads 46 are driven by the elastic restoring force of the positioning elastic sheets 45 to move inward and deeply into the recess 4 to be embedded in the positioning slot 3132. Through the structure, automatic locking and accurate positioning can be achieved during plugging and unplugging, so that the plug head 31 is kept stable engagement in the socket 40, avoiding the plug head 31 from loosening or mispositioning, thereby ensuring that the optical, fluid and electrical signals between the endoscope 20 and the main machine 10 can be continuously and reliably transmitted.

[0090] In an embodiment, the positioning beads 46 are provided in multiple numbers, and the positioning beads 46 are divided into multiple groups which are uniformly distributed in 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; and the number of the tapered slots 412 and the number of the positioning elastic sheets 45 are the same as the number of the positioning beads 46 and correspond one by one.

[0091] Among them, the multiple positioning elastic sheets 45 corresponding to the positioning beads 46 of the same group can be provided as: the fixed end (i.e. the end fixedly connected with the outer seat body 411) is integrally provided, and the free end (i.e. the end abutting against the positioning beads 46), which can facilitate installation.

[0092] In the embodiment, the plug head 30 includes a positioning ring 313, and the guide surface 3131 and the positioning slot 3132 are formed on the positioning ring 313.

[0093] Next, continue to refer to Figures 7 to 9 The socket 40 has a third optical connecting portion 441, a fourth optical connecting portion 443 and a second fluid connecting portion 444 which communicate with the recess 4.

[0094] Correspondingly, the plug head 31 includes a first base 311, a second base 312 protruding forward from the front end surface 3110 of the first base 311, a first optical connecting portion 341 receiving light from the socket 40, a second optical connecting portion 342 outputting light to the socket 40, and a first fluid connecting portion 343 in fluid communication with the socket 40.

[0095] That is, when the plug part 31 is inserted into the cavity 4 of the socket 40: the first optical connection part 341 is connected with the third optical connection part 441 to receive light from the socket 40, so that the host 10 provides light source for the endoscope 20; the second optical connection part 342 is connected with the fourth optical connection part 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 part 343 is connected with the second fluid connection part 444, and the first fluid connection part 343 transports gas or water to the inside of the endoscope 20 through the pipeline 21 to meet the needs of irrigation and ventilation.

[0096] The first optical connection part 341, the second optical connection part 342 and the first fluid connection part 343 are respectively arranged on any one of the front end face 3110 of the first base 311 and the front end face 3120 of the second base 312.

[0097] Therefore, the connector 500 of the embodiment can realize the plug-in connection of optical, fluid and electrical signals in a smaller radial range at the same time, and when applied to the medical device 100, can meet the high-quality image transmission, stable gas-liquid delivery and reliable signal connection of the endoscope 20 in the process of surgery or examination, and has the effects of simplifying the structure, improving the positioning accuracy and reducing the processing difficulty.

[0098] In an embodiment, the first optical connection part 341 and the first fluid connection part 343 are respectively arranged on the front end face 3110 of the first base 311, and the second optical connection part 342 is arranged on the front end face 3120 of the second base 312.

[0099] Therefore, the first optical connection part 341 and the first fluid connection part 343 can be connected with the corresponding interfaces in the socket 40 at the same time when being inserted, so that the light source and the gas-liquid delivery can be quickly plugged in the same position, and the second optical connection part 342 is independently connected on the other front end face 3120, which is beneficial to reduce the mutual interference between different optical connections and optimize the signal transmission path, thereby further improving the connection stability and the image quality.

[0100] And, the arrangement, in combination with the first electrical connection 344 provided on the outer circumferential surface of the first base 311, can effectively avoid the installation complexity and alignment difficulty caused by excessive dense arrangement of interfaces on the same end surface, make the overall structure more simple, and make the outer circumferential surface of the plug 31 only need to arrange the first electrical connection 344, avoid the problems of poor contact and difficult docking caused by the arrangement of multiple interfaces on the outer circumferential surface, and also reduce the processing precision requirement of the first electrical connection 344, thereby maintaining good contact and signal transmission between the host 10 and the endoscope 20, thereby further improving the operation reliability, service life and processing cost of the connector 500 as a whole on the basis of ensuring high efficiency transmission of each channel.

[0101] In the embodiment, the first base 311 and the second base 312 are provided in a cylindrical structure and are concentrically arranged, that is, the central axis of the first base 311 is collinear with the central axis of the second base 312. Of course, in the variant embodiment, if the first base 311 is changed to other columnar shape (i.e. non-cylindrical), a central axis can also be defined approximately in the columnar extension direction thereof.

[0102] The first base 311 and the second base 312 can be provided integrally or separately and fixedly assembled together, which is not limited in the application.

[0103] Regarding the specific structure of the first optical connection 341, it can include an external soft shell and an optical fiber inside, and can also include a sapphire bevel mirror at the front end. In this way, the light emitted by the socket 40 to the first optical connection 341 can be fully received through the sapphire bevel mirror, thereby improving the utilization rate of light.

[0104] In an embodiment, the first optical connection 341 is provided in a tube structure, and the third optical connection 441 has a hole structure, and the two are implemented in plug-in butt joint. Of course, the application is not limited thereto.

[0105] The second optical connection 342 is provided in a tube structure, and the fourth optical connection 443 has a hole structure, and the two are implemented in plug-in butt joint. Of course, the application is not limited thereto.

[0106] Regarding the specific structure of the second optical connection 342, it can also include an external soft shell and an optical fiber inside, and can also include a glass flat lens at the front end.

[0107] In addition, in an embodiment, the first fluid connection 343 can be used for gas flow, for example, for transmitting the gas flow provided by the host 10 to the endoscope 20. However, it is not limited thereto.

[0108] ​The first fluid connection part 343 is provided in a tube structure, and the second fluid connection part 444 is provided in a hole structure, and the two are connected by plug-in.

[0109] Next, referring to Figure 8 And Figure 9 The plug-in connector 30 further comprises a housing 32 between the plug-in connector 30 and the pipeline 21.

[0110] The housing 32 is configured to be held by a user to facilitate the user to plug in the plug-in connector 30 and the socket 40.

[0111] The housing 32 is further provided with a first interface 37, a second interface 38 and a third interface 39. As described above, the first interface 37 can be in communication with the host 10 through the water pipe, the second interface 38 is in communication with the water pump 80, and the third interface 39 is in communication with the suction pump 90. The housing 32 is internally provided with a plurality of tubes / wires, 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 tube / 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 be arranged in the housing 32 and integrated into a bundle extending backward to the endoscope 20.

[0112] In an embodiment of the present application, the plug-in part 31 further comprises a first circuit board 35.

[0113] The positioning ring 313 is assembled between the first base 311 and the housing 32. Specifically, the positioning ring 313 can be connected by any feasible means such as bonding, welding, riveting, screwing or buckling. Of course, in a variant embodiment, the positioning ring 313 can be integrally formed with the first base 313 or integrally arranged with the housing 32.

[0114] The first circuit board 35 is fixedly assembled to the inner side of the first base 311 or the positioning ring 313. A plurality of first electrical connection parts 344 are provided as a plurality of conductive pieces (such as PIN pins), one end of which is arranged at the circuit board 35 and electrically connected thereto, and the other end is arranged on the outer peripheral surface of the first base 311.

[0115] Next, referring to Figure 2 And Figure 3 The plug-in connector 30 further comprises a guide block 36 arranged on the outer periphery of the plug-in part 31, and the socket 40 further comprises a guide groove 4111 communicating with the cavity 4. When the plug-in part 31 is plugged 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 realizing the guiding effect during plugging on the one hand, and enhancing the connection stability on the other hand.

[0116] In addition, the socket 40 further comprises a heat dissipation member 47 located at least partially in front of the recess 4, the heat dissipation member 47 being in contact with the front end of the first optical connecting part 341, and the heat dissipation member 47 having a plurality of heat dissipation fins 471 extending outward around the first optical connecting part 341.

[0117] In this way, by arranging the heat dissipation member 47 in front of the recess 4 and closely coupling it with the first optical connecting part 341, the excess heat generated by the light source of the main machine 10 can be timely taken away, so as to avoid burns or performance degradation caused by excessively high temperature during plugging. The heat dissipation fins 471 are distributed in the circumferential direction 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 used in cooperation with the endoscope 20 and the main machine 10.

[0118] In addition, referring to Figures 3 to 7 The socket 40 further comprises a support seat 41 and a U-shaped light shielding member 48.

[0119] Specifically, the support seat 41 constitutes a support framework of other components of the socket 40, and is fixed relative to the plug-in head 30 in the plugged state of the plug-in head 30 and the socket 40.

[0120] The support seat 41 comprises the outer seat body 411 described above and a bracket part 413, and the bracket part 413 and the outer seat body 413 are fixedly arranged, and can be directly connected or indirectly connected.

[0121] The U-shaped light shielding member 48 is movably connected to the bracket part 413 of the support seat 41, and has a shielding position and a release position relative to the bracket part 413. In the shielding position, the light shielding member 48 is located on the light exit path behind the third optical connecting part 441, for example, in the channel 4110 behind the third optical connecting part 441, to block the light at the third optical connecting part 441 from exiting the recess 4; in the release position, the light shielding member 48 exits the light exit path behind the third optical connecting part 441, for example, exits the channel 4110.

[0122] When the first optical connecting part 341 moves forward to be connected to the third optical connecting part 441, under the pushing of the first optical connecting part 341, the light shielding member 48 moves from the shielding position to the release position.

[0123] In this way, by this light shielding design, the high-brightness light can be effectively blocked from leaking before the plug-in head 31 is inserted, preventing irritation to the operator, and when the first optical connecting part 341 is inserted, the shielding is automatically released and the fiber coupling is completed, realizing reliable connection of the light source and the endoscope 20.

[0124] In an embodiment, the light shielding piece 48 is rotationally connected to the support base 41 to change between the shielding position and the releasing position. For example, in an embodiment, the upper end of the light shielding piece 48 is rotationally connected to the support base 41, and the lower end of the light shielding piece 48 enters the light exit path behind the third light connecting part 441 in the shielding position; thus, when the first light connecting part 341 exits the recessed cavity 4, the light shielding piece 48 is kept in the shielding position under the action of gravity. Alternatively, in another variant embodiment, the socket 40 further comprises a reset spring arranged between the support base 41 and the light shielding piece 48, and when the first light connecting part 341 exits the recessed cavity 4, the light shielding piece 48 is kept in the shielding position under the action of the reset spring.

[0125] By automatically returning the light shielding piece 48 to the shielding position under the action of gravity or the spring, when the first light connecting part 341 completely separates from the socket 40, the high-brightness light source is again shielded, and the operating environment can be continuously and safely protected, while the structure is simple and the reliability is high.

[0126] In summary, compared with the prior art, the embodiment has the following beneficial effects: in the case where the first electrical connecting part 344 is arranged on the outer periphery of the plug part 31, and the second electrical connecting part 442 corresponding to the first electrical connecting part 344 is arranged on the socket clamp 42, the socket clamp 42 can be further self-adaptively fine-tuned in the radial direction, thereby further improving the electrical contact reliability between the plug connector 30 and the socket 40, avoiding poor contact or signal transmission loss caused by manufacturing and assembly tolerances; at the same time, excessive wear during plugging and unplugging can be reduced, thereby ensuring long-term stable transmission of electrical signals between the endoscope 20 and the main machine 10, and prolonging the overall service life of the connector 500.

[0127] The detailed description listed above is only a specific description of the feasible embodiments of the utility model, and is not used to limit the protection scope of the utility model, and equivalent embodiments or changes made without departing from the spirit of the utility model art should be included in the protection scope of the utility model.
