The insertion part of the endoscope can enter the human body through the natural orifices of the human body or through a small incision formed by surgery. When in use, the insertion part is guided into the organ to be examined to directly observe changes in the relevant parts.

[0003] In the endoscope system, some adjacent components are connected by a connector assembly, for example, the cable is connected to the host through an electrical connector assembly, and the optical cable is connected to the host through an optical connector assembly. However, the connection strength between the connector and the connector in the above connector assembly is not high, and it is easy to loosen during use. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide an endoscope system and its connector spring piece and connector, which can solve the problem that the connection strength between the current connector and the plug is not high and is easy to loosen during use.

[0005] In order to solve the above technical problems, this application is implemented as follows:

[0006] In a first aspect, an embodiment of the present application provides a connector spring piece of an endoscope, comprising a spring piece body, the spring piece body having a pressing end and a connecting end arranged opposite to each other, the pressing end being provided with at least one deformation slit, one end of the deformation slit extending close to the edge of the pressing end away from the connecting end, so as to form a pressing portion for pressing a connector of a connector on both sides of the deformation slit, the pressing portion and the deformation slit being alternately arranged along a first direction, the first direction intersecting with the extension direction of the deformation slit,

[0007] The connecting end is provided with at least two connecting parts, and the spring body can be installed to the connector body through the connecting parts. The at least two connecting parts are arranged at intervals along the first direction, and in the direction extending from the pressing end to the connecting end, each connecting part is respectively arranged opposite to each pressing part.

[0008] In the second aspect, an embodiment of the present application provides a connector for an endoscope, which is used to connect to a plug-in connector, including a connector body, a snap-in connector and a connector spring as described above, wherein at least two mounting holes are provided on the connector body, and a snap-in connector is movably provided in each mounting hole, and a connecting portion is connected to the connector body, and a pressing portion covers at least a portion of the mounting hole, and the pressing portion is used to press the snap-in connector so that the snap-in connector is snap-fitted with the card slot of the plug-in connector.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0020] The endoscope system and its connector spring piece and connector provided in the embodiment of the present application are described in detail below through specific embodiments and their application scenarios in combination with the accompanying drawings.

[0021] The current connector includes a connector body, a spring sheet and a card connector. The spring sheet is fixedly connected to the connector body through a connecting hole. The connector body is provided with a conical hole. The card connector is movably arranged in the conical hole and can move toward or away from the spring sheet. The current connector is provided with a card slot. During the process of plugging the connector and the connector, the spring sheet can press the card connector tightly in the card slot, and the connector and the connector are connected.

[0022] The current spring sheet is provided with a plurality of deformation slits spaced along the length direction of the spring sheet, and pressing parts are formed on both sides of the deformation slits. The deformation slits and the pressing parts are arranged alternately, and there is a deformation slit between two adjacent pressing parts, and each pressing part presses a card connector. The inventor found that in the plug-in and pull-out direction of the connector, the connection hole and the deformation slit on the spring sheet are arranged opposite to each other, so the distance between the connection hole and the corresponding pressing part is relatively large. Since the fulcrum of the pressing part is the connection point between the connection hole and the connector body, the use of this structure will increase the distance between the fulcrum and the pressing part, thereby increasing the distance that the pressing part extends out of the fulcrum, reducing the elasticity of the pressing part, and further reducing the pressing force of the pressing part on the card connector. Obviously, this will cause the connection strength between the connector and the corresponding plug connector to be low, and the connector is easy to loosen from the plug connector.

[0023] like Figures 1 to 5As shown, an embodiment of the present application discloses a connector spring clip of an endoscope, including a spring clip body 100, the spring clip body 100 having a pressing end 200 and a connecting end 300 arranged back to back, the pressing end 200 being provided with at least one deformation slit 210, one end of the deformation slit 210 extending close to the edge of the pressing end 200 away from the connecting end 300, so as to form a pressing portion 220 for pressing a connector clip 500 on both sides of the deformation slit 210, respectively, the pressing portion 220 and the deformation slit 210 are alternately arranged along a first direction, the first direction intersects with the extension direction of the deformation slit 210, that is, the angle between the first direction and the extension direction of the deformation slit 210 may be an acute angle or a right angle, and the first direction is not parallel to the extension direction of the deformation slit 210.

[0024] The connecting end 300 is provided with at least two connecting parts 310, and the spring body 100 can be installed to the connector body 400 through the connecting parts 310. At least two connecting parts 310 are arranged at intervals along the first direction, and in the direction extending from the pressing end 200 to the connecting end 300, each connecting part 310 is respectively arranged opposite to each pressing part 220.

[0025] In the embodiment of the present application, in the direction extending from the pressing portion 220 to the portion of the spring body 100 located outside the pressing portion 220, the connecting portion 310 is arranged opposite to the pressing portion 220, that is, the connecting portion 310 and the deformation slit 210 are arranged in a staggered manner. Compared with the relative arrangement of the connecting portion 310 and the deformation slit 210, the embodiment of the present application can reduce the distance between the connecting portion 310 and the corresponding pressing portion 220. After the spring body 100 is installed on the connector body 400, the pressing portion 220 is arranged opposite to the deformation slit 210. The fulcrum of 0 is the connection point between the connecting portion 310 and the connector body 400. Therefore, after reducing the distance between the connecting portion 310 and the corresponding pressing portion 220, the distance between the fulcrum and the corresponding pressing portion 220 can be reduced, thereby reducing the distance that the pressing portion 220 extends out of the fulcrum to increase the elasticity of the pressing portion 220, thereby increasing the pressing force of the pressing portion 220 on the card connector 500, thereby increasing the connection strength between the connector and the corresponding plug 600, and preventing the connector and the plug 600 from loosening.

[0026] In an optional embodiment, the spring sheet body 100 is an arc-shaped structural member extending along an arc direction, and the first direction is parallel to the arc direction. In this embodiment, the spring sheet body 100 is an arc-shaped structural member, that is, the spring sheet body 100 is bent, so that the spring sheet body 100 can adapt to the connector body 400 with an arc surface on the outer peripheral surface. In addition, bending stress will be generated during the bending of the spring sheet body 100, so the deformation seam 210 is provided at the pressing end 200 to release the bending stress of the spring sheet body 100 to prevent the spring sheet body 100 from being damaged.

[0027] Alternatively, in an optional embodiment, the spring sheet body 100 is a flat structural member, and in this case, the spring sheet body 100 can be adapted to the connector body 400 having a flat outer peripheral surface.

[0028] In an optional embodiment, the deformation slit 210 penetrates the shrapnel body 100 along the thickness direction of the shrapnel body 100, and the deformation slit 210 extends to the edge of the pressing end 200 away from the connecting end 300. In this embodiment, the deformation slit 210 penetrates the shrapnel body 100 along the thickness direction of the shrapnel body 100, and the deformation slit 210 extends to the edge of the pressing end 200, that is, the deformation slit 210 is an open hollow gap, and there is no other component between the two side walls of the deformation slit 210 to connect two adjacent pressing parts 220, so that the internal stress of the shrapnel body 100 can be further released, thereby preventing the shrapnel body 100 from being damaged when bending. Of course, the deformation slit 210 may not penetrate the shrapnel body 100 along the thickness direction of the shrapnel body 100, and it may not extend to the edge of the pressing end 200 away from the connecting end 300.

[0029] In an optional embodiment, the connection parts 310 are provided with at least two groups, each group of the connection parts 310 includes at least two connection parts 310 arranged at intervals along the first direction, and the at least two groups of the connection parts 310 are arranged at intervals along the direction extending from the pressing end 200 to the connecting end 300. In this embodiment, the connection parts 310 are provided with at least two groups, and the at least two groups of the connection parts 310 are arranged at intervals along the direction extending from the pressing end 200 to the connecting end 300, that is, the distances between the connection parts 310 and the pressing parts 220 in different groups of the connection parts 310 are not equal, and the connection point between the connection parts 310 and the connector body 400 is the fulcrum of the pressing part 220, so that the connection parts 310 of different groups are connected to the connector body 400, and the distance between the fulcrum and the corresponding pressing part 220 can be changed, so that the distance of the pressing part 220 extending from the fulcrum can be changed, so as to change the elasticity of the pressing part 220, and then adjust the pressing force of the pressing part 220 on the clamping member 500. Of course, only one group of connecting parts 310 may be provided, and this application is not limited to this.

[0030] In an optional embodiment, the extension length of the deformation slit 210 in the first direction is less than the extension length of the pressing portion 220 in the first direction. In this embodiment, the extension length of the deformation slit 210 is less than the extension length of the pressing portion 220, so that the distance between two adjacent pressing portions 220 can be reduced. When the extension length of the pressing portion 220 is constant, the structure of this embodiment can reduce the extension length of the pressing end 200 in the first direction, so as to reduce the external dimensions of the spring body 100. Of course, the extension length of the deformation slit 210 in the first direction can also be greater than or equal to the extension length of the pressing portion 220 in the first direction.

[0031] In an optional embodiment, the connection portion 310 is a connection hole, and the deformation slit 210 extends in the direction from the connection end 300 to the pressing end 200. In the first direction, the spring sheet body 100 has two side edges 110 arranged opposite to each other, and the axes of the connection holes on both sides are closer to the corresponding side edges 110 than the symmetry axes of the corresponding pressing portions 220, wherein the symmetry axes of the pressing portions 220 are parallel to the extension direction of the deformation slit 210. In this embodiment, the connection portion 310 is a connection hole, and the connection hole can be used to pass a screw, and one end of the screw is connected to the connector body 400 after passing through the connection hole, so that the spring sheet body 100 can be installed on the connector body 400 by using the screw. The connection holes on both sides are two connection holes close to the corresponding side edges 110, and the pressing portions 220 corresponding to the connection holes are the pressing portions 220 opposite to the connection holes, and the symmetry axes of the pressing portions 220 are as follows. Figure 1 The dotted line shown is the central axis of the connecting hole, and the axes of the connecting holes on both sides are closer to the corresponding side edges 110 than the symmetric axes of the corresponding pressing portions 220, so that the connection point between the spring body 100 and the connecting portion 310 body is closer to the side edge 110 to prevent the side edge 110 from curling, thereby improving the connection stability between the spring body 100 and the connector body 400. Of course, the connecting portion 310 can also be a buckle, in which case the connector body 400 is provided with a mating portion that is mated with the buckle, and the buckle can be engaged with the mating portion.

[0032] In an optional embodiment, the inner wall of the deformation slot 210 in the extension direction thereof is an inwardly concave arc surface, so that the internal stress of the spring sheet body 100 can be released to prevent the spring sheet body 100 from being damaged.

[0033] The embodiment of the present application also discloses a connector for an endoscope, which is used to connect with a plug connector 600, and includes a connector body 400, a card connector 500, and a connector shrapnel as described in any of the above embodiments. The connector body 400 is provided with at least two mounting holes 410, and each mounting hole 410 is movably provided with a card connector 500. The connecting portion 310 is connected to the connector body 400, and the pressing portion 220 covers at least part of the mounting hole 410. The pressing portion 220 is used to press the card connector 500 so that the card connector 500 is engaged with the card slot 610 of the plug connector 600. Optionally, the card connector 500 can be a card connection ball, a card connection column, etc. After the spring body 100 of this embodiment is installed on the connector body 400, the fulcrum of the pressing portion 220 is the connection point between the connecting portion 310 and the connector body 400. Therefore, after reducing the distance between the connecting portion 310 and the corresponding pressing portion 220, the distance between the fulcrum and the corresponding pressing portion 220 can be reduced, thereby reducing the distance that the pressing portion 220 extends out of the fulcrum to increase the elasticity of the pressing portion 220, thereby increasing the pressing force of the pressing portion 220 on the card connector 500, thereby increasing the connection strength between the connector and the corresponding plug 600, and preventing the connector and the plug 600 from loosening.

[0034] In an optional embodiment, the connector body 400 is provided with a positioning portion 420, and the positioning portion 420 is used to position and cooperate with the positioning and matching portion 620 of the plug connector 600, so that the connector body 400 and the plug connector 600 are matched at the circumferential upper limit of the connector body 400. In this embodiment, the positioning portion 420 and the positioning and matching portion 620 can be positioned and matched, so that the connector body 400 and the plug connector can be installed to a preset position, and the positioning portion 420 and the positioning and matching portion 620 can also prevent the connector body 400 from rotating, so as to prevent the connector body 400 and the plug connector from deviating from the preset position.

[0035] In a further embodiment, positioning portions 420 are provided on opposite sides of the axis of the connector body 400, and the shapes and / or sizes of the two positioning portions 420 are different. For example, the shapes of the two positioning portions 420 are different, such as one positioning portion 420 is a positioning convex portion and the other positioning portion 420 is a positioning concave portion; the sizes of the two positioning portions 420 are different, and the sizes here can be width, length, thickness, arc length or radius, etc. In the case where the shapes of the two positioning portions 420 are the same but the sizes are different, the cross-sectional areas or longitudinal cross-sectional areas of the two positioning portions 420 can be different. In this embodiment, the shapes and / or sizes of the two positioning portions 420 are different, so that the connector body 400 can be prevented from being installed misplaced, so as to achieve the purpose of foolproofing.

[0036] The embodiment of the present application further discloses an endoscope system, including the connector described in any of the above embodiments. The endoscope system referred to in the embodiment of the present application can be a bronchoscope system, a pyeloscope system, an esophagoscope system, a gastroscope system, a colonoscope system, an otoscope system, a nasoscope system, a stomatoscope system, a laryngoscope system, a colposcope system, a laparoscope system, an arthroscopic system, etc. The embodiment of the present application does not specifically limit the type of the endoscope system.
