Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a waterproof sealing joint and a cable. Background Art

[0002] During the disinfection process of the endoscope after reuse, the cable part also needs to be disinfected. In order to ensure that the cable maintains waterproof performance when immersed in disinfectant, the relevant technology adopts the method of installing a waterproof cap on the connector head. However, the waterproof cap is inconvenient during use. When the connector needs to be inserted into the host, the waterproof cap must be unscrewed first, and then screwed back on after use. This process is cumbersome and time-consuming.

[0003] Therefore, providing a waterproof sealing connector and cable that is easy to use is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0004] The invention discloses a waterproof sealing joint and a cable, so as to solve the technical problem of the waterproof sealing joint in the related art being troublesome to use.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions:

[0006] In a first aspect, a waterproof sealing joint is disclosed, comprising:

[0007] A connector connected to a far end of the cable;

[0008] A movable member is slidably connected to the distal end of the connecting member along the axial direction of the connecting member;

[0009] A sealing sheet, one end of which is connected to the movable member, and the other end of which extends to the opening at the far end of the connecting member, and the moving path of the end intersects with the extension line of the cable;

[0010] The sealing sheet extends to one end of the distal opening of the connecting piece, and opens or closes the opening of the connecting piece as the movable piece moves.

[0011] In some embodiments, when the movable member moves toward the connecting member, the opening of the connecting member gradually opens;

[0012] When the movable member moves away from the connecting member, the opening of the connecting member is gradually closed.

[0013] In some solutions, an elastic member is further included, and the movable member is slidably connected to the connecting member via the elastic member.

[0014] In some solutions, a slide groove is provided at the distal end of the connecting member, and the slide groove extends along the axial direction of the connecting member;

[0015] The proximal end of the movable part is embedded in the slide groove and can drive the sealing sheet to move in the slide groove.

[0016] In some embodiments, there is only one sealing sheet, and when one end of the sealing sheet extending to the distal opening of the connector stops against the inner wall of the movable part or the inner wall of the connector, the distal opening of the connector is closed.

[0017] In some embodiments, there are two sealing sheets, and the two sealing sheets extend to one end of the distal opening of the connector and move toward or in opposite directions;

[0018] When the two sealing sheets extend to one end of the distal end opening of the connector and stop, the distal end opening of the connector is closed.

[0019] In some embodiments, two sealing sheets extend to the end surface of the distal opening of the connector, one of which is provided with a protrusion and the other is provided with a groove;

[0020] When the two sealing sheets extend to one end of the distal opening of the connecting piece and stop, the protrusion is embedded in the groove.

[0021] In some embodiments, the sealing sheet has a deformation portion and a stop portion; one end of the deformation portion extends to the distal end opening of the connector and is connected to the stop portion;

[0022] The deformation part bends as the movable part moves, and the rigidity of the stop part is greater than the rigidity of the deformation part.

[0023] In some embodiments, the projection of the movable member along its own axis is rectangular;

[0024] There are foolproof marks on the connectors.

[0025] In a second aspect, a cable is disclosed, wherein the distal end of the cable is provided with the waterproof sealing joint in the first aspect.

[0026] The technical solution adopted by the present invention can achieve the following beneficial effects:

[0027] In the process of connecting the waterproof sealing joint of the present application with the host, the operator slides the movable part, and the movable part drives the sealing plate to move during the movement, so that the opening of the connecting part is opened. At this time, the cable is connected to the outside world. The connecting part is then inserted into the socket of the host, and the endoscope connected to the front end of the cable transmits information to the host through the cable. After the waterproof sealing joint is separated from the host, the operator slides the movable part in the opposite direction, and the movable part drives the sealing plate to move during the movement, so that the opening of the connecting part is closed. At this time, the cable is isolated from the outside world, and the cable can be immersed in disinfectant for disinfection. The waterproof sealing joint of the present invention only needs to slide the movable part up and down to connect or isolate the cable from the outside world. Compared with the method of rotating the waterproof cap in the prior art, the operation is simpler and faster. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0048] 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.

[0049] In each embodiment of the present application, "proximal end" and "distal end" refer to the position of each component relative to the user in the use environment, wherein the end closer to the user is designated as the "proximal end" and the end farther from the user is designated as the "distal end".

[0050] The reusable endoscope needs to be disinfected after use. In order to ensure that the cable 200 maintains waterproof performance when immersed in disinfectant, the related art adopts a method of installing a waterproof cap on the connector head. However, the applicant found that the waterproof cap is inconvenient to use. When the connector needs to be inserted into the host 300, the waterproof cap must be unscrewed first, and then screwed back on after use. This process is cumbersome and time-consuming.

[0051] The following is combined with Figures 1 to 14 , a waterproof sealing joint 100 and a cable 200 provided in the present application are described in detail through specific embodiments and their application scenarios.

[0052] Some embodiments of the present application provide a waterproof sealing joint 100, such as Figure 1 As shown, it includes a connecting member 110 , a movable member 120 and a sealing sheet 130 .

[0053] like Figure 1 , Figure 3 , Figure 5 , Figure 7 , Fig. 9 and Fig.11 As shown, the connector 110 is connected to the distal end of the cable 200. The connector 110 is a main component for connecting to the socket of the host 300. When the connector 110 is used for an endoscope, when the connector 110 is inserted into the socket of the host 300, the images and data captured by the endoscope can be transmitted to the host 300 in real time for processing and display.

[0054] like Figure 1 , Figure 4 , Figure 6 , Figure 8 , Fig.10 and Fig.12 As shown, the movable part 120 is slidably connected to the distal end of the connecting part 110 along the axial direction of the connecting part 110, one end of the sealing sheet 130 is connected to the movable part 120, and the other end extends to the opening 111 at the distal end of the connecting part 110, and the moving path of this end intersects with the extension line of the cable 200, so that the cable 200 can be isolated or connected to the outside world through the movement of the sealing sheet 130.

[0055] During the connection with the host 300, the operator slides the movable part 120, and the movable part 120 drives the sealing plate 130 to move during the movement, so that the opening 111 of the connecting part 110 is opened. At this time, the cable 200 is connected to the outside world; after the waterproof sealing joint 100 is separated from the host 300, the operator slides the movable part 120 in the opposite direction, and the movable part 120 drives the sealing plate 130 to move during the movement, so that the opening 111 of the connecting part 110 is closed. At this time, the cable 200 is isolated from the outside world.

[0056] Specifically, the movable member 120 is sleeved on the outside of the distal end of the connecting member 110, and the side wall of the distal end of the connecting member 110 has a penetrating mounting groove 115, such as Fig.14One end of the sealing sheet 130 is connected to the inner wall of the movable member 120, and the other end is bent and extends through the mounting groove 115 to the distal opening 111 of the connecting member 110, thereby realizing the function of opening or closing the distal opening 111 of the connecting member 110 by moving the movable member 120 along the connecting member 110.

[0057] It should be noted that the height of the mounting groove 115 is not greater than the thickness of the sealing sheet 130 to ensure the sealing performance. In this embodiment, the height of the mounting groove 115 is slightly less than the thickness of the sealing sheet 130. Since the sealing sheet 130 has a certain deformation capacity, it will be squeezed when passing through the mounting groove 115, and the sealing sheet 130 can always maintain a tendency of deformation recovery at the position of the mounting groove 115, which helps to increase the sealing performance of the connection between the sealing sheet 130 and the mounting groove 115.

[0058] In addition, Fig.14 As shown, the inner wall of the connecting member 110 is provided with a guide groove 114, and one end of the sealing sheet 130 extending to the opening 111 is embedded in the guide groove 114 and can slide in the guide groove 114. The guide groove 114 guides the movement of the sealing sheet 130, and during the movement of the movable member 120, it can ensure that the movement trajectory of the sealing sheet 130 is always the same, thereby ensuring that the sealing sheet 130 can stably close the opening 111 at the far end of the connecting member 110.

[0059] In some embodiments, Figure 4 , Figure 6 , Figure 8 , Fig.10 and Fig.12 As shown, the moving path of the sealing sheet 130 extending to one end of the opening 111 is perpendicular to the inner wall of the connecting member 110 .

[0060] In some embodiments, a moving path of the sealing sheet 130 extending to one end of the opening 111 forms an angle with an inner wall of the connecting member 110 .

[0061] In this embodiment, the moving path of the sealing sheet 130 extending to one end of the opening 111 is preferably perpendicular to the inner wall of the connector 110. In this way, when the sealing sheet 130 closes the opening 111 of the connector 110, the entire plane of the end of the sealing sheet 130 is in direct contact with the sealing surface, and the sealing effect is better.

[0062] It should be noted that the sealing surface may be any one of the end surface of another sealing sheet 130 , the inner wall of the movable member 120 , and the inner wall of the connecting member 110 .

[0063] As a matter of course, the width of the sealing sheet 130 projected along the axial direction of the connector 110 is greater than or equal to the axial projection of the opening 111 of the connector 110 , so that the sealing sheet 130 can separate the inside and the outside of the connector 110 .

[0064] In this embodiment, the projection of the opening 111 of the connecting member 110 along the axial direction of the connecting member 110 is circular. Fig.14 As a matter of course, the shape of the opening 111 of the connector 110 is not limited to a circle, but may also be a rectangle, an ellipse, etc., as long as it is ensured that after the sealing sheet 130 opens the opening 111, the projection of the cable 200 along the axial direction of the connector 110 and the projection of the opening 111 along the axial direction of the connector 110 do not overlap.

[0065] One end of the sealing sheet 130 extends to the distal opening 111 of the connecting member 110 and opens or closes the opening 111 of the connecting member 110 as the movable member 120 moves.

[0066] In the first method, if Figure 3-Figure 12 As shown, when the movable member 120 moves toward the connecting member 110, the opening 111 of the connecting member 110 gradually opens; when the movable member 120 moves away from the connecting member 110, the opening 111 of the connecting member 110 gradually closes.

[0067] In the second mode, when the movable member 120 moves toward the connecting member 110 , the opening 111 of the connecting member 110 is gradually closed; when the movable member 120 moves away from the connecting member 110 , the opening 111 of the connecting member 110 is gradually opened.

[0068] Among them, this embodiment adopts the first method. In this method, when the operator inserts the connecting member 110 into the socket of the host 300, the movable member 120 will contact the socket of the host 300, so that the movable member 120 moves toward the connecting member 110 to open the opening 111 of the connecting member 110. That is, when the connecting member 110 is inserted into the socket of the host 300, the movable member 120 does not need to be provided with an additional power source to drive the movement of the movable member 120. In addition, the movable member 120 gradually moves after the connecting member 110 enters the socket of the host 300, which can also prevent the cable 200 from being exposed to the surgical environment and contaminated in advance.

[0069] In addition, using the first method, after the connector 110 enters the socket of the host 300, the movable member 120 overlaps the connector 110, and the movable member 120 does not occupy the space in the socket of the host 300, making it easier to connect the cable 200 to the socket of the host 300.

[0070] like Figure 4 , Figure 6 , Figure 8 , Fig.10 and Fig.12 As shown, the connecting member 110 is provided with a slide groove 112, and the slide groove 112 extends along the axial direction of the connecting member 110. The proximal end of the movable member 120 is embedded in the slide groove 112, and can drive the sealing sheet 130 to move in the slide groove 112.

[0071] Specifically, the outer wall of the movable member 120 abuts against the outer wall of the slide groove 112, and the sealing sheet 130 is connected to the inner wall of the movable member 120. There is a gap between the inner wall of the movable member 120 and the inner wall of the slide groove 112, and the gap allows the sealing sheet 130 to pass through. It should be noted that the radial width of the slide groove 112 is greater than or equal to the radial width of the movable member 120 and the sealing sheet 130, so that the movable member 120 can drive the sealing sheet 130 to move in the slide groove 112.

[0072] The slide groove 112 provides a mounting base for the movable member 120 to be mounted on the connecting member 110, and guides the movable member 120 to move along the connecting member 110. Due to the existence of the slide groove 112, the movable member 120 can move a long distance along the connecting member 110, so that the sealing sheet 130 can completely open the opening 111 of the connecting member 110.

[0073] In this embodiment, if Figure 4 , Figure 8 and Fig.10 As shown, when the sealing sheet 130 closes the connecting member 110, the distal end of the movable member 120 does not exceed the distal end of the connecting member 110, thereby reducing the possibility that the movable member 120 is accidentally moved due to collision between the connecting member 110 and the outside world.

[0074] like Figure 4 , Figure 6 , Figure 8 , Fig.10 and Fig.12 As shown, the movable member 120 is slidably connected to the connecting member 110 through the elastic member 140. When the connecting member 110 is inserted into the socket of the host 300, the movable member 120 moves toward the connecting member 110, and the elastic member 140 is gradually compressed during the process, so that the elastic member 140 stores elastic potential energy. When the connecting member 110 is separated from the socket of the host 300, the elastic potential energy of the elastic member 140 is released, driving the movable member 120 to move in a direction away from the connecting member 110, thereby causing the sealing sheet 130 to close the opening 111 of the connecting member 110.

[0075] In addition, during the process of separating the connector 110 from the socket of the host 300, as the connector 110 is pulled out, the movable part 120 is constantly resetting. When the connector 110 is completely separated from the socket of the host 300, the movable part 120 also moves to the initial position, thereby allowing the sealing sheet 130 to close the opening 111 of the connector 110, thereby preventing the cable 200 from being exposed to the surgical environment after the connector 110 is completely separated from the socket of the host 300.

[0076] Specifically, the elastic member 140 is disposed in the slide slot 112 and connected to the proximal end of the movable member 120. As the proximal end of the movable member 120 moves in the slide slot 112, the elastic member 140 is compressed or released.

[0077] In this embodiment, the elastic member 140 may be a spring sheet, a coil spring or others, which is not limited in this embodiment.

[0078] In this embodiment, the number of elastic members 140 may be 1, 2, 3, 4 or more, and may be flexibly set according to usage requirements, which is not limited in this embodiment.

[0079] like Figure 8 , Fig.10 and Fig.12 As shown, in an optional solution of the present embodiment, the number of the sealing sheet 130 is 1. When one end of the sealing sheet 130 extending to the distal opening 111 of the connector 110 abuts against the inner wall of the movable member 120 or the inner wall of the connector 110, the distal opening 111 of the connector 110 is closed. In order to allow the sealing sheet 130 to isolate the external environment from the cable 200, in a solution using one sealing sheet 130, a sealing pair is formed by using the end of the sealing sheet 130 and the inner wall of the movable member 120 or the inner wall of the connector 110, thereby achieving the purpose of sealing.

[0080] In some schemes, such as Figure 8 As shown, when the opening 111 of the connector 110 is closed, the end of the sealing sheet 130 abuts against the inner wall of the connector 110, and the end of the sealing sheet 130 and the inner wall of the connector 110 form a sealing pair to isolate the interior of the connector 110 from the outside.

[0081] In some schemes, such as Fig.10 As shown, a through groove is provided on the side wall of the connecting member 110. When the opening 111 of the connecting member 110 is closed, the inner wall of the movable member 120 just covers the through groove, and one end of the sealing sheet 130 passes through the through groove and abuts against the inner wall of the movable member 120. The end of the sealing sheet and the inner wall of the movable member 120 form a sealing pair to isolate the interior of the connecting member 110 from the outside.

[0082] like Figure 4 and Figure 6 As shown, in another optional solution of this embodiment, the number of sealing sheets 130 is 2. As the movable member 120 moves, the two sealing sheets 130 extend to one end of the distal opening 111 of the connecting member 110 and move toward or away from each other. Specifically, when the movable member 120 moves toward the connecting member 110, the two sealing sheets 130 move in opposite directions and gradually open the opening 111 of the connecting member 110; when the movable member 120 moves away from the connecting member 110, the two sealing sheets 130 move toward each other and gradually close the opening 111 of the connecting member 110.

[0083] When the opening 111 of the connecting member 110 is closed, the two sealing sheets 130 extend to the ends of the distal opening 111 of the connecting member 110 and abut against each other to form a sealing pair, so as to isolate the interior of the connecting member 110 from the outside.

[0084] like Figure 6 As shown, two sealing sheets 130 extend to the end surface of the distal opening 111 of the connector 110, one of which is provided with a protrusion 132, and the other is provided with a groove 133. When the opening 111 of the connector 110 is closed, the protrusion 132 at the end of one sealing sheet 130 is embedded in the groove 133 at the end of the other sealing sheet 130, thereby increasing the contact area of ​​the two sealing sheets 130 when they stop, and further improving the sealing performance of the two sealing sheets 130 when they stop.

[0085] As a matter of course, the shape of the protrusion 132 matches the shape of the groove 133 , and when the protrusion 132 is embedded in the groove 133 , the side wall of the protrusion 132 is completely in contact with the side wall of the groove 133 .

[0086] In this embodiment, the shape of the protrusion 132 and the groove 133 is a triangle. As a matter of course, the shape of the protrusion 132 and the groove 133 can also be a rectangle, a semicircle, a sawtooth or other shapes, which can be flexibly set according to the use requirements, and this embodiment does not limit this.

[0087] like Figure 4 , Figure 8 , Fig.10 and Fig.12 As shown, whether one sealing sheet 130 or two sealing sheets 130 are used, the sealing sheet 130 has a deformation portion 134 and a stop portion 131. The deformation portion 134 is made of a soft material, such as rubber but not limited to rubber. The sealing sheet 130 is bent all the time during the process of opening and closing the opening 111 of the connecting member 110. Therefore, the deformation portion 134 made of a soft material can well adapt to the bending of the sealing sheet 130 during the movement, so as to increase the service life of the deformation portion 134.

[0088] One end of the deformation portion 134 extends to the distal opening 111 of the connecting member 110 and is connected to the abutment portion 131 . The rigidity of the abutment portion 131 is greater than the rigidity of the deformation portion 134 .

[0089] In some embodiments, Figure 4 As shown, when the opening 111 of the seal is closed, the end faces of the two stop parts 131 stop. The stop parts 131 have a certain rigidity. When the two stop parts 131 stop, they have sufficient structural stability and will not collapse, ensuring the reliability of the sealing pair and further ensuring the sealing performance.

[0090] In this embodiment, one of the end surfaces of the two stop portions 131 is provided with a protrusion 132 , and the other end surface is provided with a groove 133 .

[0091] In some embodiments, Figure 8 As shown, when the opening 111 of the sealing member is closed, the end surface of the stop portion 131 abuts against the inner wall of the connecting member 110. The stop portion 131 has a certain rigidity, and when the end surface of the stop portion 131 abuts against the inner wall of the connecting member 110, the structure has sufficient stability and will not collapse, thereby ensuring the reliability of the sealing pair and further ensuring the sealing performance.

[0092] In some embodiments, Fig.10 As shown, when the opening 111 of the sealing member is closed, the end surface of the stop portion 131 passes through the through slot and abuts against the inner wall of the movable member 120. The stop portion 131 has a certain rigidity, and when the end surface of the stop portion 131 abuts against the inner wall of the movable member 120, the structure has sufficient stability and will not collapse, thereby ensuring the reliability of the sealing pair and further ensuring the sealing performance.

[0093] It should be noted that, since the stop portion 131 has a certain rigidity, when the opening 111 of the connecting member 110 is fully opened, Fig.12 As shown, the stop portion 131 will not be bent by the installation groove 115, so as to provide a certain protection for the stop portion 131 and prevent the stop portion 131 from breaking.

[0094] like Figure 1 and Fig.14As shown, the projection of the movable part 120 along its own axial direction is a rectangle. For the movable part 120 with a rectangular projection, during the installation of the sealing sheet 130 and the movable part 120, the sealing sheet 130 abuts against the inner wall of the movable part 120 without bending. During the process of the sealing sheet 130 passing through the installation groove 115, the sealing sheet 130 can be smoothly bent, and the sealing sheet 130 can smoothly pass through the installation groove 115. If the projection of the movable part 120 along its own axial direction is arc-shaped, the sealing sheet 130 will collapse radially during the process of bending through the installation groove 115, and contact with the inner wall of the installation groove 115, thereby affecting the movement of the sealing sheet 130.

[0095] Correspondingly, the portion where the connecting member 110 and the movable member 120 are slidably connected is rectangular, so that during the movement of the sealing sheet 130 , the inner wall can abut against the outer wall of the connecting member 110 , thereby increasing the stability of the sealing sheet 130 during the movement.

[0096] like Figure 1 As shown, the connector 110 is provided with a foolproof mark 113. The foolproof mark 113 serves as a reminder to the operator, preventing the operator from inserting the connector by mistake or inserting the connector in reverse, and ensuring that the connector 110 can be inserted into the socket of the host 300 in the correct manner.

[0097] Correspondingly, a prompt matching the fool-proof mark 113 is provided at the corresponding socket position of the host 300. When inserting the connector 110 into the socket of the host 300, it is only necessary to align the fool-proof mark 113 with the prompt of the host 300 so that the connector 110 can be smoothly inserted into the socket of the host 300.

[0098] For example, Figure 2 As shown, one of the sockets of the host 300 has an Arabic numeral "2", and the anti-fool mark 113 on the connector 110 is also an Arabic numeral "2". By corresponding the Arabic numeral "2" on the connector 110 and the Arabic numeral "2" on the socket of the host 300, the connector 110 can be smoothly inserted into the socket of the host 300.

[0099] For example, Figure 2 As shown, another socket of the host 300 has an Arabic numeral "3", and the anti-fool mark 113 on another connector 110 is also an Arabic numeral "3" (the connector 110 is not shown in the figure). By corresponding the Arabic numeral "3" on the connector 110 and the Arabic numeral "3" on the socket of the host 300, the connector 110 can be smoothly inserted into the socket of the host 300.

[0100] The cable 200 provided in some embodiments of the present application is as follows: Figure 1 , Figure 2 and Fig.13As shown, the distal end of the cable 200 is provided with the above-mentioned waterproof sealing joint 100 .

[0101] When the cable 200 is used for an endoscope, the proximal end of the cable 200 is connected to the endoscope, and the images and data detected by the endoscope can be transmitted to the host 300 through the cable 200 for processing, and the images are displayed on the host 300.

[0102] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0103] In addition, it should be noted that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in a reverse order according to the functions involved. For example, the described methods may be performed in an order different from that described, and various steps may be added, omitted, or combined. In addition, features described with reference to certain examples may be combined in other examples.

[0104] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
