Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to an endoscope locking and sealing device. It also relates to an endoscope including the aforementioned endoscope locking and sealing device. Background Technology

[0002] During surgery, endoscopes are frequently used for observation of lesions, to assist in treatment, or to guide surgical instruments, such as video laryngeal masks, video endotracheal intubations, and video bronchial intubations during anesthesia. Endoscopes are needed for short-term, long-term, and temporary placement during surgery. Therefore, when using endoscopes to assist other medical devices, they need to be locked in place after being positioned appropriately.

[0003] Currently, most endoscopes on the market are fixed by setting a fixed connector or multiple limiting components on the camera tube. This method of fixation can only fix the insertion depth of the camera at one or more fixed positions, and cannot freely insert to the required depth according to the doctor's observation site, thus failing to fully meet clinical needs.

[0004] During surgery, after the endoscope is placed, the area around the camera channel needs to be sealed to prevent bacteria or viruses from entering or exiting. For example, the patient's airway and the anesthesia machine form a closed circulation channel to prevent pathogens from contaminating the surrounding environment through respiratory airflow, and to prevent airborne viruses and dust from entering the patient's respiratory system. Therefore, the camera channel of respiratory endoscopic monitoring devices also needs to be sealed. However, current endoscope camera channels only lock the camera tube and camera, and cannot effectively seal the channel. Some instruments have a transparent sealing cap at the exit of the camera channel, creating a blind hole with a transparent sealing cap. The camera cannot pass through the camera channel exit and can only move within the camera channel. If it is necessary to insert the camera into a deeper area for examination, this cannot be achieved. This results in the camera's depth position not being adjustable or fixed as needed, and the camera channel cannot be completely sealed, leading to poor sealing performance. Utility Model Content

[0005] This application provides an endoscope locking and sealing device that solves the technical problem of not being able to meet the requirements of arbitrary depth position adjustment and sealing.

The movable core is movable relative to the camera tube in a first direction. The elastic sealing element has a first sealing surface and a second sealing surface. The first sealing surface is used to seal against the outer wall of the camera tube under the locking force of the latch and to disengage from the outer wall of the camera tube under the unlocking force of the latch. The second sealing surface is used to seal at least a portion of the cavity wall of the inner cavity under the locking force and to disengage from the cavity wall under the unlocking force.

[0009] A latch, disposed on the connector and / or the movable core, is used to provide the locking force or the unlocking force to the movable core.

[0011] In some embodiments, the first bottom surface is distributed circumferentially along the movable core body of the movable core, and the top surface is distributed circumferentially along the sealing body of the elastic seal.

[0012] In some embodiments, the second sealing surface includes a first sealing sub-surface, a second sealing sub-surface, and a third sealing surface;

[0013] The first sealing sub-surface is disposed on the side of the elastic seal facing the movable core, and is used to fit the second bottom surface of the movable core;

[0014] The second sealing sub-surface is disposed on the side peripheral surface of the elastic seal and is used to fit the cavity wall of the inner cavity;

[0015] The third sealing surface is disposed on the bottom surface of the elastic seal and is used to fit the bottom surface of the inner cavity.

[0016] In some embodiments, the latch is rotatably connected to the first connector or the second connector, and the latch is provided with a locking surface for locking the first connector and the second connector, so that the movable core moves toward the connector and the second bottom surface of the movable core fits and seals the first sealing surface.

[0017] In some embodiments, the latch is rotatably connected to the second connector. The latch includes a pressing part, a first connecting part, two second connecting parts, and two rotating parts. The two second connecting parts are arranged opposite to each other. The first connecting part connects the pressing part and the two second connecting parts. The two rotating parts are respectively fixed to the outer walls of the two second connecting parts. The locking surface is located at the corner of the second connecting part. The length of the pressing part is greater than the length of the two second connecting parts.

[0018] In some embodiments, the locking surface is an inclined surface or an outwardly convex surface.

[0021] This application also provides an endoscope including the endoscope locking and sealing device described in any of the above claims.

[0022] In this embodiment, when the elastic seal is not under locking force, the camera tube can smoothly pass through the inner hole of the elastic seal, and the movable core can move up and down within the connector cavity. When the latch is closed, the movable core moves downward and deforms the elastic seal. The elastic seal deforms under the pressure of the movable core, causing the first sealing surface to wrap and seal the camera tube passing through the inner hole of the elastic seal. Simultaneously, the second sealing surface seals at least a portion of the cavity wall around the outlet of the inner cavity. The movable core moves downward and deforms the elastic seal, creating an interference fit between the outer diameter of the elastic seal and the inner diameter of the connector cavity, while simultaneously creating an interference fit between the inner hole of the elastic seal and the camera tube, thus fixing and sealing the camera tube. This allows for positioning of the camera tube at any position, solving the problem of the camera tube not being able to be fixed and sealed at any position. When it is necessary to open and lock the latch, simply press the latch gently. The latch rotates along its pivot within the latch fixing hole of the connector, thus opening and locking conveniently.

[0061] This application provides an endoscope locking and sealing device that solves the technical problems of the inability to adjust the camera insertion depth and poor sealing performance, enabling the camera to be freely inserted to any depth as needed and maintain a sealed state, thereby meeting clinical needs.

[0062] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0063] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the specification of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the specification of this application are intended to cover non-exclusive inclusion.

[0064] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0065] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

[0067] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0068] In this application, "multiple" means two or more (including two).

[0069] During surgery, doctors use endoscopes to observe lesions or perform treatments using other medical instruments. To ensure the accuracy and safety of the visualization process, the endoscope needs to be locked after it is placed in the appropriate position. However, existing endoscope locking devices cannot freely adjust the insertion depth; they can only place the camera in a fixed position and cannot freely adjust the insertion depth as needed. Furthermore, the camera channel cannot be completely sealed when locked, making it easy for bacteria and viruses to enter and exit.

[0070] The endoscope locking and sealing device provided in this application allows for free adjustment of the insertion depth and can seal and fix the camera tube in the locked state. While ensuring the camera's free movement, it can achieve positional fixation and sealing at any depth in the locked state. By setting a connector, a movable sealing component, and a latch, the camera tube can be inserted into the inner cavity of the connector and exit from the connector's outlet. Under the unlocking force of the latch, the movable core of the movable sealing component can move along a first direction, allowing the camera tube to be inserted into the inner cavity of the connector. Under the locking force of the latch, the elastic sealing elements of the first and second sealing surfaces are sealed and fixed in position, forming a seal in the locked state to prevent bacteria and viruses from entering.

[0071] This application provides an endoscope locking and sealing device suitable for fixing sights in various visual channels, especially for use with video laryngeal masks (such as...). Figure 1 As shown), visual endotracheal intubation (such as...) Figure 6 (as shown), and other respiratory visual devices such as visual endotracheal intubation.

[0072] refer to Figures 2 to 5The endoscope locking and sealing device provided in this application includes a connector 11, a movable sealing component 12, and a latch 13. The connector 11 has an inner cavity 112, an insertion port 111, and an outlet 113. The insertion port 111 and the outlet 113 are respectively connected to the inner cavity 112 on both sides. The insertion port 111 allows the movable sealing component 12 to be inserted, and provides space for the installation of the movable core 121 in the movable sealing component 12. The outlet 113 is used for the camera tube 20 to be led out. The movable sealing component 12 includes a movable core 121 and an elastic sealing element 122. The movable core 121 passes through the insertion port 111, and at least a portion of the movable core 121 is disposed in the inner cavity 112. The movable core 121 is clearance-fitted with the inner cavity 112 and the camera tube 20 so that the movable core 121 can move relative to the camera tube 20 and the inner cavity 112 along a first direction X. The elastic seal 122 has a first sealing surface 122a and a second sealing surface 122b. The first sealing surface 122a faces the camera tube 20, and the second sealing surface 122b faces the inner cavity 112 of the connector 11. The first sealing surface 122a is used to seal against the outer wall of the camera tube 20 under the locking force of the latch 13, and to disengage from the outer wall of the camera tube 20 under the unlocking force of the latch 13. The second sealing surface 122b is used to seal at least a portion of the cavity wall of the inner cavity 112 under the locking force, and to disengage from the cavity wall outlet 113 under the unlocking force. The camera tube 20 can be freely inserted to any depth to meet different operational requirements.

[0073] It should be noted that the first direction in this application can be... Figure 2 and Figure 3 The X direction in the cavity 112 is the direction along the axis of the inner cavity 112, which is also the insertion direction of the movable core 121.

[0074] like Figures 9 to 12 As shown. Both the connector 11 and the movable sealing component 12 can be cylindrical, such as a cylindrical, square, triangular, polygonal, or cylindrical structure with an arc-shaped surface. The size and shape of the inner cavity 112 of the connector 11 are adapted to the outer contour size and shape of the movable core 121 and the elastic sealing component 122 to ensure a good seal between the inner cavity 112 and the movable core 121 and the elastic sealing component 122. The insertion port 111 and the outlet port 113 can be arranged on both sides of the inner cavity 112 along the first direction X, for example, they can be coaxially arranged on the connector 11 to meet the insertion requirements of the camera tube 20 along the first direction X, or they can be arranged vertically or obliquely. The movable core 121 can be inserted into or sleeved on the outer wall of the camera tube 20 with a clearance fit. In addition, there is a clearance fit between the movable core 121 and the cavity wall of the inner cavity 112 to ensure that the movable core 121 can move relative to the inner cavity 112 of the connector 11 and the camera tube 20. The movable core 121 moves up and down to squeeze the elastic seal 122, deforming it and fixing the camera tube 20.

[0075] The elastic seal 122 can be made of an elastic material, such as rubber or silicone, and can undergo elastic deformation under external pressure. The elastic seal 122 can be positioned below the movable core 121 along a first direction X. The elastic seal 122 has a first sealing surface 122a on the side facing the camera tube 20 and a second sealing surface 122b on the side facing the inner cavity 112. Both sealing surfaces can be circular, square, polygonal, or curved, and this embodiment is not limited in this respect. The first sealing surface 122a seals part of the outer peripheral surface of the camera tube 20, and the second sealing surface 122b seals the space between the lower part of the inner cavity 112 and the movable core 121, specifically the space near the outlet 113 at the bottom of the inner cavity 112, and the space between the sidewall of the inner cavity 112 and the camera tube 20. In the locked state, the elastic seal 122 forms a reliable seal, preventing external bacteria and viruses from entering.

[0076] The latch 13 is provided on the connector 11 and / or the movable sealing member 12 to provide a locking force or an unlocking force to the movable sealing member 12, so that the elastic seal 122 seals under the action of the locking force, or the elastic seal 122 moves relative to the camera tube 20 and the connector 11 under the action of the unlocking force.

[0077] like Figures 8 to 13 As shown. During installation, the latch 13 is combined with the movable core 121 and / or the elastic seal 122. The elastic seal 122 and the movable core 121 are then inserted into the inner cavity 112 in sequence. The camera tube 20 is then inserted into the inner hole of the movable core 121 and the elastic seal 122, and then passes out from the outlet 113 of the connector 11. After the position is adjusted, the latch 13 is used to fasten the movable core 121 and the elastic seal 122 together so that the first sealing surface 122a and the second sealing surface 122b are in contact.

[0078] In use, the camera tube 20 is inserted into the inner hole of the elastic seal 122 in the inner cavity 112 of the connector 11, and then the latch 13 is closed by external force. The movable core 121 descends and squeezes the elastic seal 122, thereby fixing the camera tube 20 and sealing the camera channel 40.

[0079] This application is based on the cooperation of the movable core 121 and the elastic seal 122, and uses the latch 13 to control the up and down movement of the movable core 121 by closing and opening, so as to realize the locking and unlocking functions. The latch 13 provides locking force or unlocking force to the movable core 121. After the elastic seal 122 is deformed by the compression of the movable core 121, it forms a fixation and seal on the camera tube 20.

[0080] This application provides an endoscope locking and sealing device 10 that allows for free adjustment of the insertion depth and locking to seal the camera channel 40. Through the interaction of the movable core 121, the elastic seal 122, and the latch 13, the camera tube 20 can remain fixed and sealed in the locked state. Specifically: The insertion portion of the camera tube 20 is equipped with the elastic seal 122, which allows the camera tube 20 to pass through when in its natural state. When the latch 13 is closed, the movable core 121 moves downward, pressing down on the elastic seal 122 and deforming it. After deformation, the first sealing surface 122a of the elastic seal 122 forms an interference contact with the outer diameter of the camera tube 20, and simultaneously, the second sealing surface 122b of the elastic seal 122 also forms an interference contact with the cavity wall of the inner cavity 112 of the connector 11, thereby achieving fixation and sealing of the camera tube 20. Thus, the camera tube 20 can be freely inserted to any depth and fixed in the locked state, ensuring the sealing of the camera channel 40.

[0081] like Figure 7 As shown. In one specific embodiment, the movable core 121 includes a first connector 1211, and the connector 11 includes a second connector 114. The side of the first connector 1211 facing the second connector 114 is provided with a first bottom surface 1211a, and a top surface 114a is provided on the side of the second connector 114 facing the movable core 121. The side of the connector 11 facing a sealing portion is provided with a top surface 114a. The first bottom surface 1211a is used to fit and seal with the top surface 114a under the action of locking force.

[0082] like Figure 4 As shown. A first connector 1211 is disposed on one side of the movable core 121 and fixedly connected to the outer wall of the movable core 121. A first bottom surface 1211a is disposed on the bottom surface of the first connector 1211, which can be a plane, curved surface, sawtooth surface, trapezoidal surface, etc. A second connector 114 is disposed on one side of the connector 11 and fixedly connected to the outer wall of the connector 11. The second connector 114 is disposed opposite to the first connector 1211, and a top surface 114a is disposed on the side of the second connector 114 facing the movable core 121, i.e., on the top surface of the second connector 114. A latch 13 is disposed on the first connector 1211 and / or the second connector 114, and the two can be detachably connected or rotatably connected, etc.

[0083] Under the locking force applied by the latch 13, the first bottom surface 1211a of the first connector 1211 can be completely fitted to the top of the second connector 114, so that the movable core 121 and the connector 11 can be sealed, thereby improving the sealing performance between the movable core 121 and the connector 11.

[0084] Further, the second sealing surface 122b includes a first sealing sub-surface 1221b, a second sealing sub-surface 1222b, and a third sealing sub-surface 1223b. The first sealing sub-surface 1221b is disposed on the side of the elastic sealing member 122 facing the movable core 121, that is, the top surface of the movable core 121. The first sealing sub-surface 1221b is used to adhere to the second bottom surface 1211b of the movable core 121 under the action of the latch 13, and to seal against the second bottom surface 1211b of the movable core 121. The second sealing sub-surface 1222b is disposed on the side peripheral surface of the elastic sealing member 122, and can adhere to the cavity wall of the inner cavity 112 under the action of the latch 13, and seal against the inner cavity 112. The third sealing sub-surface 1223b is disposed on the bottom surface of the elastic sealing member 122, and can adhere to and seal against the bottom surface 115 of the inner cavity under the action of the latch 13. This allows for the formation of a completely sealed structure between the movable core 121 and the elastic seal 122, as well as between the elastic seal 122 and the inner cavity 112.

[0085] Continue to refer to Figure 4 The first sealing surface 1221b is disposed on the top surface of the elastic seal 122. The area of ​​the first sealing surface 1221b is larger than the bottom area of ​​the movable core 121, and the bottom of the movable core 121 is completely covered by the first sealing surface 1221b in an orthographic view. Thus, under the action of locking force, a sealing structure is formed between the movable core 121 and the elastic seal 122 to ensure the sealing performance between the two.

[0086] Optionally, the first bottom surface 1211a is distributed circumferentially along the body of the movable core 121, and the top surface 114a is distributed circumferentially along the body of the elastic seal 122. This forms a circumferential sealing structure surrounding the camera tube 20, which can improve sealing efficiency and further enhance the sealing effect.

[0087] Regarding the connection method of the latch 13, in one specific embodiment, the latch 13 is rotatably connected to the first connector 1211 or the second connector 114, for example, through a rotating shaft. The latch 13 is provided with a locking surface 135. Under the action of external force, the latch 13 rotates relative to the rotating shaft so that the locking surface 135 of the latch 13 locks the first connector 1211 and the second connector 114, thereby causing the movable core 121 to move down and gradually squeeze the elastic sealing member 122, causing it to deform and thus seal the inner cavity 112 of the camera tube 20 and the connector 11. When the first connector 1211 contacts the second connector 114 so that the first bottom surface 1211a and the top surface 114a are completely attached, the second bottom surface 1211b of the movable core 121 adheres to and seals the first sealing sub-surface 1221b. The movable core 121 and the connector 11 achieve complete sealing, thus achieving complete sealing between the components in the endoscope locking and sealing device 10, thereby ensuring the sealing effect.

[0088] Regarding the structure of the latch 13, in a first specific embodiment, the latch 13 is rotatably connected to the second connector 114. The latch 13 includes a pressing part 131, a first connecting part 132, two second connecting parts 133, and two rotating parts 134. The two second connecting parts 133 are arranged opposite to each other. The first connecting part 132 connects the pressing part 131 and the two second connecting parts 133. The two rotating parts 134 are respectively fixed to the outer walls of the two second connecting parts 133. The locking surface 135 is provided at the corner of the second connecting part 133, and the length of the pressing part 131 is greater than the length of the two second connecting parts 133.

[0089] like Figures 8 to 13 As shown. The pressing part 131 has a pressing surface, on which an anti-slip structure can be provided to increase the contact friction between the pressing part and the hand. The two second connecting parts 133 can be plate-shaped or block-shaped, and are generally vertically distributed. The first connecting part 132 is a plate-shaped or block-shaped structure, vertically connecting the pressing part 131 and the two second connecting parts 133. The two rotating parts 134 are coaxially distributed on the outer wall surface of the second connecting member 114 and are rotatably mounted on the rotating connecting member of the connector 11. The rotating part 134 can be a rotating shaft. The length of the pressing part 131 on one side of the rotating part 134 is greater than the length of the two second connecting parts 133 on the other side, and the lengths of the two second connecting parts 133 are equal.

[0090] This forms a lever structure with the rotating part 134 as the rotation center. When the pressing part 131 is pressed, under the action of the rotating part 134, the pressing part 131 drives the second connecting part 133 to rotate around the rotation center. When it rotates to a certain angle, the locking surface 135 contacts the second connecting member 114. After that, it continues to rotate, and the locking surface 135 continuously presses against the second connecting member 114 and pushes the second connecting member 114 toward the first connecting member 1211, pushing the movable core 121 to achieve a seal with the elastic locking member and the connector 11.

[0091] The locking surface 135 can be an inclined surface or a convex surface. The inclined surface can be an inclined plane or an inclined curved surface, and the convex surface can be an arc, a trapezoid, a sawtooth, etc. Compared with the inclined surface, the convex surface can reduce the rotation angle of the latch 13 and increase the thrust.

[0092] In a second embodiment, the latch 13 is rotatably connected to the second connector 114. The latch 13 includes a pressing part 131, a first connecting part 132, a second connecting part 133, and a rotating part 134. The first connecting part 132 connects the pressing part 131 and the second connecting part 133. The rotating part 134 is disposed on the pressing part 131, and the locking surface 135 is disposed on the inner side of the pressing part 131. The first connector 1211 is provided with a shaft 14, and the locking surface 135 is used to lock the shaft 14.

[0093] like Figures 19 to 25As shown. Specifically, the pressing part 131 has a pressing surface on which an anti-slip structure can be provided to increase the contact friction between the pressing part and the hand. The second connecting part 133 can be plate-shaped or block-shaped, and is generally vertically distributed. The first connecting part 132 is a plate-shaped or block-shaped structure, and vertically connects the pressing part 131 and the second connecting part 133. The rotating part 134 can be a rotating shaft, coaxially distributed on the outer wall surface of the second connecting member 114, and rotatably mounted on the rotating connecting member of the connector 11.

[0094] When the pressing part 131 is pressed, under the action of the rotating part 134, the pressing part 131 drives the second connecting part 133 to rotate around the rotation center. When it rotates to a certain angle, the locking surface 135 contacts the shaft 14 of the first connecting member 1211. After that, it continues to rotate, and the locking surface 135 continues to press against the shaft 14, thus achieving a seal with the shaft 14.

[0095] In the third specific embodiment, the latch 13 is rotatably connected to the first connector 1211. The latch 13 includes a pressing part 131, a first connecting part 132, a second connecting part 133, and a rotating part 134. The first connecting part 132 connects the pressing part 131 and the second connecting part 133. The rotating part 134 is disposed on the pressing part 131. The locking surface 135 is disposed on the inner side of the second connecting part 133.

[0096] like Figures 27 to 32 As shown. Specifically, the pressing part 131 has a pressing surface on which an anti-slip structure can be provided to increase the contact friction between the pressing part 131 and the second connecting part 133, which can be plate-shaped or block-shaped and generally vertically connects the pressing part 131 and the second connecting part 133. The second connecting part 133 is a plate-shaped or block-shaped structure, and the locking surface 135 is provided on the inner side of the second connecting part 133. The rotating part 134 can be a rotating shaft, coaxially distributed on the outer wall surface of the first connecting member 1211, and rotatably mounted on the rotating connecting member of the movable core 121. The second connecting member 114 is provided with a shaft 14, and the locking surface 135 is used to lock the shaft 14.

[0097] When the pressing part 131 is pressed, under the action of the rotating part 134, the pressing part 131 drives the second connecting part 133 to rotate around the rotation center. When it rotates to a certain angle, the locking surface 135 contacts the axis of the second connecting member 114. After that, as rotation continues, the locking surface 135 continuously presses against the axis 14, achieving a seal with the axis 14. Compared with the upward locking method used in the second embodiment above, this embodiment uses downward locking, which is affected by the weight of the latch 13 itself, making the operation more convenient and effortless, and the locking more secure and reliable.

[0098] The aforementioned latch 13 can be a one-piece molded structure, ensuring connection strength and reducing the number of parts, making it easier to process.

[0099] In summary, this application provides an endoscope locking and sealing device 10. When the latch 13 is closed, the movable core 121 moves downward and presses down the elastic sealing member 122, causing the elastic sealing member 122 to deform and form an interference fit on the camera tube 20, thereby fixing the camera tube 20 and sealing the camera channel 40. In this way, the camera tube 20 can be fixed at a specific depth and sealed in the locked state, meeting the needs of clinical operation.

[0100] like Figure 1 and Figure 6 As shown. In addition, this application embodiment also provides an endoscope 100, including the endoscope locking and sealing device 10 described above. The camera tube 20 is disposed in the camera channel 40, and the camera 30 is connected to the video connector 60 through the camera tube 20 and the plug 50, and finally connected to the display device 70.

[0101] The endoscope 100 has a simple structure and is easy to install. It can freely adjust the camera depth by 30 degrees and achieve fixation and sealing.

[0102] The endoscope and its locking and sealing device provided in this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of this application.
