Description

Technical Field

[0001] The utility model relates to the technical field of endoscopes, in particular to an integrated connector, an endoscope and an endoscope system. Background Art

[0002] The working principle of existing endoscopes is to insert them into the human body through the natural or artificially constructed cavities for inspection or treatment. When the endoscope is inserted into the human body, it needs to use a lens and a light source system to observe the internal situation, or it needs to use an instrument channel to introduce liquid (such as saline) for washing, or use a suction device to absorb liquid and tissue samples. In order to achieve the above functions, the endoscope and the relevant host equipment are connected to each other through various functional connectors to form an endoscope system to obtain light source, water source, negative pressure source and power source, and transmit signals.

[0003] Some endoscopes in the related art integrate the three connectors, namely the electrical connector, the gas path connector and the light guide rod, into one connector, in order to reduce the number of connector plugs, simplify the structure, and improve the convenience of plugging, so that multiple connectors can be docked with one plug. However, after integrating the above three connectors into one connector, the connectors will be overly concentrated in a limited area, increasing the risk of connector damage. For example, if one of the connectors on the connector is damaged, the entire connector will be damaged. Utility Model Content

[0004] The utility model aims to design an integrated connector, an endoscope and an endoscope system to solve the problem of high risk of connector damage.

[0005] The utility model is realized by the following technical solutions:

[0006] The utility model provides an integrated connector, which is used for an endoscope and includes a shell, an electrical connector, an air path head, a light guide rod and a protective sleeve; one end of the shell has a butt end face; the electrical connector is connected to the shell and protrudes from the butt end face along the axial direction of the shell; the air path head is connected to the shell and protrudes from the butt end face along the axial direction of the shell; the light guide rod is connected to the shell and protrudes from the butt end face along the axial direction of the shell; the protective sleeve is connected to the shell and protrudes from the butt end face along the axial direction of the shell wherein, the protective sleeve surrounds the electrical connector along the circumference of the electrical connector, the protruding length of the protective sleeve relative to the butt end face is the same as or longer than that of the electrical connector, the protruding length of the protective sleeve relative to the butt end face is longer than that of the gas path head, and, along the arrangement direction of the electrical connector and the gas path head, a straight line can be constructed between the circumference of the butt end face and the outer circumference of the protective sleeve, so that the gas path head is located in the lower area of ​​the straight line, and the light guide rod is located on the side of the straight line.

[0007] When the above-mentioned setting structure is adopted, the protective sleeve arranged around the electric connector accommodates the electric connector therein, thereby protecting the electric connector, improving the protective effect of the electric connector, and reducing the risk of the electric connector being damaged by bumps. At the same time, the straight line constructed between the outer peripheral surface of the protective sleeve and the peripheral edge of the butt end face along the arrangement direction of the electric connector and the gas circuit head is higher than the gas circuit head, so that the protective sleeve can cooperate with the part of the outer shell located at the peripheral edge of the butt end face to provide protection for the gas circuit head. In the case that the integrated connector is bumped, the part between the protective sleeve and the outer shell at the peripheral edge of the butt end face will be bumped before the gas circuit head, thereby preventing the gas circuit head from being bumped, and reducing the risk of the gas circuit head being damaged by bumps. It can be seen that this kind of integrated connector only uses a protective sleeve with a simple structure, which can not only protect the electric connector, but also protect the gas circuit head, which can reduce the risk of the electric connector and the gas circuit head being damaged by bumps, thereby reducing the risk of damage to the integrated connector.

[0008] In order to further better realize the present utility model, the following setting structure is particularly adopted: compared with the gas circuit head, the protruding length of the electrical connector relative to the butt end face is longer.

[0009] In order to further better realize the present utility model, the following setting structure is particularly adopted: the electrical connector is arranged closer to the center of the docking end face than the gas circuit head.

[0010] When the above-mentioned setting structure is adopted, the electric connector is arranged closer to the center of the docking end face than the gas circuit head, so that the protective sleeve around the electric connector can provide protection for the gas circuit head while allowing the part of the outer shell located around the docking end face to withstand more bumps, which can reduce the force of the protective sleeve being hit and reduce the risk of damage to the electric connector.

[0011] In order to further better realize the present utility model, the following setting structure is particularly adopted: the diameter of the protective sleeve is larger than the diameter of the gas path head.

[0012] When the above-mentioned setting structure is adopted, the protective sleeve with a larger diameter can provide a wider range of protection for the gas circuit head, reducing the possibility of the gas circuit head being bumped.

[0013] In order to further better realize the present utility model, the following configuration structure is particularly adopted: the housing is configured as a flat column with the major axis and the minor axis of the butt end surface being perpendicular to each other.

[0014] When the above-mentioned setting structure is adopted, the housing is set in a flat column shape, which can be conveniently held when plugging and unplugging, and the housing can have a smaller size and weight while achieving relevant functions.

[0015] In order to further better realize the utility model, the following setting structure is particularly adopted: an anti-stupid and anti-rotation structure is arranged on the outer peripheral surface of the protective sleeve.

[0016] When the above-mentioned setting structure is adopted, after the anti-study and anti-rotation structure is set on the outer circumferential surface of the protective sleeve, there is no need to set a separate anti-study and anti-rotation related structure on the outer circumferential surface of the light guide rod or the outer circumferential surface of the outer shell. It can provide anti-rotation protection and reduce the axial size of the light guide rod.

[0017] In order to better realize the utility model, the following setting structure is particularly adopted: the hole shape of the protective sleeve is set as a waist-shaped hole.

[0018] In order to further better realize the present utility model, the following setting structure is particularly adopted: the gas path head, the electrical connector and the light guide rod are arranged in sequence along a straight line.

[0019] When the above-mentioned setting structure is adopted, the electric connector is arranged between the gas circuit head and the light guide rod, and the light guide rod can be further utilized to improve the protection capability of the electric connector.

[0020] In order to further better realize the present utility model, the following setting structure is particularly adopted: the arrangement gap between the electric connector and the gas path head is smaller than the arrangement gap between the electric connector and the light guide rod.

[0021] When the above-mentioned setting structure is adopted, the layout between the electrical connector and the gas circuit head is more compact, so that the gas circuit head is located in a smaller and more solid space, and the protective effect of the protective sleeve and the shell on the gas circuit head is improved so that it can be better protected.

[0022] In order to further better realize the present invention, the following setting structure is particularly adopted: a setting gap is provided between the extension line of the straight line and the free end of the light guide rod, and the setting gap is greater than 0.

[0023] When the above-mentioned setting structure is adopted, the protective sleeve can not only protect the electrical connector, but also cooperate with the shell to protect the air path head and the light guide rod at the periphery of the mating end face, and can prevent partial collision from the upper area of ​​the extension line to the outer peripheral surface of the light guide rod. For example, when the integrated connector falls downward in a posture parallel to the straight line, the protective sleeve and the shell at the periphery of the mating end face can collide with the ground before the light guide rod, which can prevent the light guide rod from colliding with the ground or reduce the force of the collision with the ground.

[0024] The utility model also provides an endoscope, which comprises the above-mentioned integrated connector.

[0025] The utility model also provides an endoscope system, which includes the above-mentioned endoscope and a host device adapted to the endoscope, the host device includes a female seat adapted to the integrated connector of the endoscope, and the female seat includes a power supply and signal interface, an air source interface and a light source interface respectively connected to the electrical connector, the air path head and the light guide rod provided on the integrated connector of the endoscope.

[0026] The utility model has the following advantages and beneficial effects:

[0027] In the utility model, the protective sleeve arranged around the electric connector accommodates the electric connector therein, thereby protecting the electric connector, improving the protective effect of the electric connector, and reducing the risk of the electric connector being damaged by bumps. At the same time, the straight line constructed between the outer peripheral surface of the protective sleeve and the peripheral edge of the butt end face along the arrangement direction of the electric connector and the gas circuit head is higher than the gas circuit head, so that the protective sleeve can cooperate with the part of the outer shell located at the peripheral edge of the butt end face to provide protection for the gas circuit head. In the case that the integrated connector is bumped, the part between the protective sleeve and the outer shell at the peripheral edge of the butt end face will be bumped before the gas circuit head, thereby preventing the gas circuit head from being bumped, and reducing the risk of the gas circuit head being damaged by bumps. It can be seen that this kind of integrated connector only uses a protective sleeve with a simple structure, which can not only protect the electric connector, but also protect the gas circuit head, which can reduce the risk of the electric connector and the gas circuit head being damaged by bumps, thereby reducing the risk of damage to the integrated connector.

[0040] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0042] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0043] On the one hand, the present application provides an integrated connector 10, which can effectively reduce the risk of damage to the connector integrating three types of connectors: an electrical connector, an air path connector, and a light guide column. Figure 1-Figure 7 As shown, it is particularly configured as follows:

[0044] The integrated connector 10 in this embodiment is used for an endoscope to connect the endoscope to a host device (a device that provides power, light, and gas sources) to achieve related functions.

[0045] In this embodiment, the integrated connector 10 integrates the electrical connector 12, the gas circuit head 13, and the light guide rod 14, and can realize the on and off of the gas, electricity, and light of the endoscope by plugging and unplugging once.

[0046] like Figure 1 , Figure 2 and Figure 5-Figure 7 As shown, the integrated connector 10 includes a housing 11 , an electrical connector 12 , an air path head 13 , a light guide rod 14 and a protective sleeve 15 .

[0047] The electrical connector 12, the gas path head 13 and the light guide rod 14 are used to connect with the corresponding power supply and signal interface, gas source interface and light source interface on the host device respectively, so that the endoscope can realize the functions of power supply, ventilation and light guide.

[0048] like Figure 2 As shown, the housing 11 has an outer peripheral surface enclosed by an axis, and the direction of the axis is the docking direction of the housing 11 and the female socket of the host device. The housing 11 also includes a docking end face 111 arranged at its docking end and perpendicular to its axis, and a tail sleeve arranged at an end away from the docking end face 111.

[0049] like Figure 1 , Figure 2 and Figure 5-Figure 7 As shown, the electric connector 12, the gas circuit head 13 and the light guide rod 14 are integrated together on the housing 11 and arranged in parallel with each other. The electric connector 12, the gas circuit head 13 and the light guide rod 14 are distributed on the docking end surface 111 of the housing 11 without affecting each other, so that the electric connector 12, the gas circuit head 13 and the light guide rod 14 can be docked by one plug-in. Specifically:

[0050] The electrical connector 12 is fixedly connected to the housing 11 and is located inside the butt-jointed end surface 111 , while extending along the axial direction of the housing 11 to protrude from the butt-jointed end surface 111 .

[0051] The gas circuit head 13 is fixedly connected to the housing 11 and is located on the inner side of the butt end surface 111 , while extending along the axial direction of the housing 11 to protrude from the butt end surface 111 .

[0052] The light guide rod 14 is fixedly connected to the housing 11 and is located at the inner side of the butt end surface 111 , while extending along the axial direction of the housing 11 to protrude from the butt end surface 111 .

[0053] The protective sleeve 15 is fixedly connected to the housing 11 and is located at the inner side of the butt end surface 111 , while extending along the axial direction of the housing 11 to protrude from the butt end surface 111 .

[0054] like Figure 2 As shown, the protective sleeve 15 is coaxially arranged with the electrical connector 12, and the protective sleeve 15 encloses the electrical connector 12 along the circumference of the electrical connector 12. At the same time, the protruding length of the protective sleeve 15 relative to the mating end face 111 is the same as or longer than the protruding length of the electrical connector 12 relative to the mating end face 111, so that the protective sleeve 15 can provide axial protection for the electrical connector 12, and can also provide axial protection for the electrical connector 12.

[0055] like Figure 3 and Figure 4As shown, the protruding length of the protective sleeve 15 relative to the butt end face 111 is longer than the protruding length of the gas circuit head 13 relative to the butt end face 111. At the same time, along the arrangement direction of the electrical connector 12 and the gas circuit head 13, a straight line L1 can be constructed between the circumference of the butt end face 111 and the outer circumference of the protective sleeve 15 above the gas circuit head 13, so that the gas circuit head 13 can be located in the area below the straight line L1, and at the same time, the light guide rod 14 is located on the side of the straight line L1.

[0056] from Figure 3 It can be seen that the area below the so-called straight line L1 refers to the triangular area formed between the docking end face 111 and the protective sleeve 15. The triangular area constitutes a protective space, so that the gas path head 13 can "hide" therein to avoid collision with some objects.

[0057] Generally, among the lengths of the electrical connector 12, the gas circuit head 13 and the light guide rod 14 protruding from the butt end face 111, the light guide rod 14 is the longest and the gas circuit head 13 is the shortest. Figure 1-Figure 4 and Figure 6 As shown, the protruding length of the electrical connector 12 relative to the butt end face 111 is longer than the protruding length of the gas circuit head 13 relative to the butt end face 111 , and is shorter than the protruding length of the light guide rod 14 relative to the butt end face 111 .

[0058] The electrical connector 12 may be of the type Figure 2 The circular electrical connector composed of multiple pins in the embodiment may also be a plate-shaped circuit board with multiple conductive contacts arranged along the width direction of the board. The shape of the protective sleeve 15 surrounding the electrical connector 12 is related to the shape of the electrical connector 12. For example, when the electrical connector 12 is a circular electrical connector composed of multiple pins, the protective sleeve 15 is Figure 1-Figure 7 The cylindrical shape shown in .

[0059] In this embodiment, the protective sleeve 15 arranged around the electrical connector 12 accommodates the electrical connector 12 therein, thereby protecting the electrical connector 12, improving the protective effect of the electrical connector 12, and reducing the risk of the electrical connector 12 being damaged by bumps. At the same time, the straight line L1 constructed between the outer peripheral surface of the protective sleeve 15 and the peripheral edge of the docking end face 111 along the arrangement direction of the electrical connector 12 and the gas circuit head 13 is higher than the gas circuit head 13, so that the protective sleeve 15 can cooperate with the portion of the outer shell 11 located on the peripheral edge of the docking end face 111 to provide protection for the gas circuit head 13. In the case that the integrated connector 10 is bumped, the portion between the protective sleeve 15 and the outer shell 11 on the peripheral edge of the docking end face 111 will be bumped before the gas circuit head 13, thereby preventing the gas circuit head 13 from being bumped, and reducing the risk of the gas circuit head 13 being damaged by bumps. It can be seen that this type of integrated connector 10 only utilizes a protective sleeve 15 with a simple structure, which can not only protect the electrical connector 12, but also protect the air circuit head 13, thereby reducing the risk of the electrical connector 12 and the air circuit head 13 being damaged by bumps, thereby reducing the risk of damage to the integrated connector 10.

[0060] Since the protective sleeve 15 arranged on the mating end face 111 of the outer shell 11 can provide protection for the air circuit head 13 and the electrical connector 12, there is no need to arrange a circle of protective wall shell structure on the mating end face 111 along the circumference of the mating end face 111 to surround the electrical connector 12, the air circuit head 13 and the light guide rod 14 on the inner side. This can simplify the structure of the integrated connector 10.

[0061] According to some optional embodiments, Figure 1-Figure 7 As shown, the electrical connector 12 is a circular electrical connector composed of a plurality of pins, the protective sleeve 15 is roughly cylindrical, and the gas path head 13 and the light guide rod 14 are roughly cylindrical.

[0062] According to some optional embodiments, Figure 1-Figure 7 As shown, the electric connector 12 is arranged closer to the center of the butt end face 111 than the gas circuit head 13. In this way, the electric connector 12 is arranged closer to the center of the butt end face 111 than the gas circuit head 13, so that the protective sleeve 15 outside the electric connector 12 can provide protection for the gas circuit head 13 while allowing the part of the housing 11 located around the butt end face 111 to withstand more bumps, which can reduce the strength of the bumps on the protective sleeve 15 and reduce the risk of damage to the electric connector 12.

[0063] According to some optional embodiments, Figure 1-Figure 7 As shown, the diameter of the protective sleeve 15 is larger than the diameter of the gas circuit head 13. In this way, the protective sleeve 15 with a larger diameter can provide a wider range of protection for the gas circuit head 13, reducing the possibility of the gas circuit head 13 being bumped. Figure 5 and Figure 7It can be seen that the diameter of the protective sleeve 15 arranged on the periphery of the electric connector 12 is larger than the diameter of the gas circuit head 13, so that the protective sleeve 15 is at a certain distance beyond the gas circuit head 13 on both sides of the relative sides perpendicular to the arrangement direction of the electric connector 12 and the gas circuit head 13, so that the protective sleeve 15 can better protect the gas circuit head 13 and prevent objects coming from a specific angle from causing collisions with the gas circuit head 13.

[0064] According to some optional embodiments, Figure 1 , Figure 2 and Figure 4-Figure 7 As shown, the housing 11 is preferably configured as a flat columnar housing, so that the butt end surface 111 is a substantially rectangular surface, with its major axis and minor axis being perpendicular.

[0065] In this embodiment, the outer shell 11 is configured to be flat and cylindrical, which can be conveniently held during plugging and unplugging. On the premise of integrating the electrical connector 12, the air path head 13 and the light guide rod 14 and realizing related functions, the outer shell 11 can have a smaller size and weight. At the same time, the flat outer shell 11 also has a certain anti-foolproof effect, which can improve the plug-in efficiency.

[0066] Of course, the housing 11 can also be configured as a roughly cylindrical shell, but it cannot have a smaller size and weight, a good grip feel, and a certain fool-proofing ability.

[0067] According to some optional embodiments, an anti-rotation structure 151 is provided on the outer circumference of the protective sleeve 15 for matching with the socket of the female socket on the host device during mating to prevent the integrated connector 10 from rotating.

[0068] The anti-stupid and anti-rotation structure 151 can be set as Figure 1 The matching plane 151a shown in the figure starts from the free end of the protective sleeve 15 and extends toward the butt end face 111. A matching plane 151a is provided on opposite sides of the protective sleeve 15 in the radial direction, so that the outer peripheral surface of the protective sleeve 15 is formed with opposite outer arc surfaces at both ends and a surface composed of the matching planes 151a at both ends, so that the protective sleeve 15 can provide a function similar to that of a square shaft for transmitting torque, so as to adapt to the female seat on the host device to prevent fooling and stop rotation.

[0069] The anti-stupid and anti-rotation structure 151 can also be as follows Figure 6 and Figure 7 The ridge 151b shown in the figure starts from the free end of the protective sleeve 15 and extends along the axial direction of the housing 11 toward the butt end face 111. A plurality of ridges 151b are arranged on the outer circumference of the protective sleeve 15, so that the protective sleeve 15 can be matched with the slide groove arranged on the female seat on the host device to prevent fooling and stop rotation.

[0070] In this embodiment, after the anti-study and anti-rotation structure 151 is set on the outer circumferential surface of the protective sleeve 15, there is no need to separately set a related anti-study and anti-rotation structure on the outer circumferential surface of the light guide rod 14 or the outer circumferential surface of the outer shell 11. This can provide anti-rotation protection and reduce the axial size of the light guide rod 14.

[0071] According to some optional embodiments, Figure 2 and Figure 5 As shown, the hole type of the protective sleeve 15 is set as a waist-shaped hole. In this way, the waist-shaped hole can be adapted to the waist-shaped seat body of the female seat installation pin interface on the host device through the waist-shaped hole, which has a rotation-stopping effect.

[0072] According to some optional embodiments, Figure 5 and Figure 7 As shown, the gas circuit head 13, the electric connector 12 and the light guide rod 14 are arranged in sequence along a straight line on the butt end surface 111, so that the electric connector 12 is arranged between the gas circuit head 13 and the light guide rod 14, and the light guide rod 14 can be further used to improve the protection capability of the electric connector 12.

[0073] Preferably, the housing 11 is configured as Figure 2 The flat column shape shown, the butt end face 111 is Figure 5 The substantially rectangular shape shown in the figure, and the long axis and the short axis of the butt end face 111 are perpendicular. The arrangement path of the gas path head 13, the electrical connector 12 and the light guide rod 14 coincides with the long axis of the butt end face 111.

[0074] According to some optional embodiments, Figure 5 and Figure 7 As shown, the arrangement gap between the electric connector 12 and the gas circuit head 13 is smaller than the arrangement gap between the electric connector 12 and the light guide rod 14. Since the protective sleeve 15 is coaxially arranged with the electric connector 12, the arrangement gap between the protective sleeve 15 and the gas circuit head 13 is smaller than the arrangement gap between the protective sleeve 15 and the light guide rod 14. This makes the layout between the electric connector 12 and the gas circuit head 13 more compact, so that the gas circuit head 13 is located in a smaller and more solid space, and improves the protective effect of the protective sleeve 15 and the housing 11 on the gas circuit head 13, so that it is better protected.

[0075] Preferably, when the air circuit head 13, the electrical connector 12 and the light guide rod 14 are arranged in sequence along a straight line, the air circuit head 13 and the light guide rod 14 are arranged as close to the periphery of the docking end face 111 as possible, and the electrical connector 12 is not arranged at the center position of the docking end face 111, but is more inclined to the air circuit head 13.

[0076] According to some optional embodiments, Figure 3As shown, when the gas path head 13, the electrical connector 12 and the light guide rod 14 are arranged in sequence along a straight line, there is a gap between the extension line L2 of the straight line L1 extending away from the docking end face 111 and the free end of the light guide rod 14, and the gap is the set gap A, and the set gap A is greater than 0.

[0077] In this embodiment, the protective sleeve 15 can not only protect the electrical connector 12, but also cooperate with the shell 11 to protect the air path head 13 and the light guide rod 14 around the mating end face 111, so as to prevent partial collision with the outer peripheral surface of the light guide rod 14 from the upper area of ​​the extension line L2. For example, when the integrated connector 10 falls downward in a posture parallel to the straight line L1, the protective sleeve 15 and the shell 11 around the mating end face 111 can collide with the ground before the light guide rod 14, so as to prevent the light guide rod 14 from colliding with the ground or reduce the force of the collision with the ground.

[0078] According to some optional embodiments, the outer shell 11 is assembled from a sleeve and an end cover, the sleeve provides the outer peripheral surface of the outer shell 11, and at the butt end of the outer shell 11, the end surfaces of the end cover and the sleeve are roughly flush, so that the end cover and the sleeve together provide a portion of the end surface respectively to form a butt end surface 111 at the butt end of the outer shell 11.

[0079] On the other hand, the present application provides an endoscope, which is particularly configured as follows:

[0080] In this embodiment, the endoscope includes the integrated connector 10 in any of the above embodiments. The integrated connector 10 is connected to the operation part of the endoscope through a cable to connect to the operation part and related devices inside the insertion part.

[0081] On the other hand, the present application provides an endoscope system, which has the following configuration:

[0082] In this embodiment, the endoscope system includes the endoscope in the above embodiment and a host device adapted to the endoscope, the host device includes a female seat adapted to the integrated connector 10 of the endoscope, and the female seat includes a power supply and signal interface, a gas source interface, and a light source interface respectively connected to the electric connector 12, the gas path head 13, and the light guide rod 14 provided on the integrated connector 10 of the endoscope. The endoscope provided with the integrated connector 10 can simultaneously realize ventilation, power supply (including the ability to provide power and signal transmission) and light guide functions through a single plug-in.

[0083] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto.
