Description

Technical Field

[0001] This application relates to the technical field of medical devices, and more specifically, to an endoscope locking and sealing device. It also relates to an endoscope including the above endoscope locking and sealing device. Background Art

[0002] During the operation, an endoscope is often used to observe the lesion site, assist in treatment, or guide surgical instruments, such as a visible laryngeal mask, visible tracheal intubation, visible bronchial intubation, etc. during anesthetic surgery. There are requirements for short-term placement, long-term placement, and temporary placement of the endoscope during the operation. Therefore, when the endoscope is used in conjunction with other medical devices, after the endoscope is placed in the appropriate position, it needs to be locked.

[0003] Currently, most endoscopes on the market are fixed by setting a fixed joint or multiple limiters on the camera tube. This fixing method can only fix the insertion depth of the camera at one or more fixed positions, and cannot freely insert the depth according to the needs of the doctor to observe the part, and cannot fully meet the clinical requirements.

[0004] During the operation, after the endoscope is placed, the area around the camera tube needs to be sealed to prevent bacteria or viruses from entering and leaving. For example, a closed-loop channel is formed between the patient's respiratory tract and the anesthesia machine to prevent germs from contaminating the surrounding environment through the respiratory airflow, and at the same time, to prevent viruses and dust in the air from entering the patient's respiratory system. Then, the camera channels of respiratory endoscope monitoring devices also need to be sealed. However, the current camera channels for placing endoscopes only have the functions of locking the camera tube and the camera, and cannot effectively seal. Some instruments are equipped with a transparent sealing end cap at the outlet of the camera channel, making the camera channel form a blind hole with a transparent sealing end cap. The camera cannot penetrate the outlet of the camera channel and can only move within the camera channel. If the camera needs to be inserted deeper for inspection, it cannot be achieved. This results in the depth position of the camera not being adjustable and fixed arbitrarily according to needs, and the camera channel cannot be fully sealed, and the sealing effect is not good.

[0061] The present application provides an endoscopic locking and sealing device, which solves the technical problems of inability to adjust the insertion depth of the camera and poor sealing performance, enabling the camera to be freely inserted to any depth as needed and maintaining a sealed state, thereby meeting clinical requirements.

[0062] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present 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 terms used in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application; the terms "comprising" and "having" and any variations thereof in the specification of this application are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in this application are used to distinguish different objects and not to describe a specific order or primary-secondary relationship.

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

[0065] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "mounted", "connected", "coupled", "attached" shall be construed broadly, e.g., it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the internal communication of two elements.

[0067] In the embodiments of this application, the same reference numerals represent the same components, and for the sake of brevity, in different embodiments, the detailed description of the same components is omitted. It should be understood that the thickness, length, width, etc. of various components shown in the drawings in the embodiments of this application, as well as the overall thickness, length, width, etc. of the integrated device, are only for illustrative purposes and should not constitute any limitation to this application.

[0068] The term "plurality" as used in this application refers to two or more (including two).

[0069] During surgery, doctors use endoscopes to observe the lesion site or use other medical devices for treatment. In order to ensure the accuracy and safety of visual operations, the endoscope device needs to be locked after it is placed in the appropriate position. However, the endoscope locking device in the prior art cannot freely adjust the insertion depth. It can only place the camera in a fixed position and cannot freely adjust the insertion depth as needed. In addition, the camera channel cannot be completely sealed in the locked state, which makes it easy for bacteria and viruses to enter and exit.

[0070] The endoscope locking and sealing device provided by the present application can freely adjust the insertion depth and can seal and fix the camera tube in the locked state. While ensuring the free movement of the camera head, it can achieve position fixation and sealing at any depth in the locked state. By setting a joint, a movable sealing component and a lock buckle, the camera tube can be inserted into the inner cavity of the joint and pass out from the outlet of the joint. Under the unlocking force of the lock buckle, the movable core of the movable sealing component can move along the first direction, so that the camera tube can be inserted into the inner cavity of the joint. Under the locking force of the lock buckle, the first sealing surface and the second sealing surface elastic seal are sealed and fixed in position, and at the same time, a seal is formed in the locked state to prevent bacteria and viruses from entering.

[0071] The present application provides an endoscope locking and sealing device, which is applicable to a visual device fixing device for a variety of visual channels, especially for a visual laryngeal mask (such as Figure 1 ), visual endotracheal intubation (as shown), Figure 6 As shown), visual endobronchial tubes and other respiratory visual equipment.

[0072] refer to Figures 2 to 5。The endoscopic locking and sealing device provided by the present application includes a connector 11, a movable sealing member 12, and a lock 13. The connector 11 is provided with an inner cavity 112, an insertion port 111, and a lead-out port 113. The insertion port 111 and the lead-out port 113 are respectively communicated with the inner cavity 112 on both sides of the inner cavity 112. The insertion port 111 is for the movable sealing member 12 to be inserted, providing space for the installation of the movable core 121 in the movable sealing member 12, and the lead-out port 113 is for the camera tube 20 to be led out. The movable sealing member 12 includes a movable core 121 and an elastic sealing member 122. The movable core 121 passes through the insertion port 111 and at least part of the movable core 121 is disposed in the inner cavity 112. The movable core 121 has a clearance fit 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 the first direction X. The elastic sealing member 122 is provided with 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 the outer wall of the camera tube 20 under the action of the locking force of the lock 13, and to disengage from the outer wall of the camera tube 20 under the action of the unlocking force of the lock 13. The second sealing surface 122b is used to seal at least part of the wall of the inner cavity 112 under the action of the locking force, and to disengage from the wall at the lead-out port 113 under the action of the unlocking force. The camera tube 20 can be freely inserted to any depth to meet different operation requirements.

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

[0074] As Figures 9 to 12 shown. Both the connector 11 and the movable sealing member 12 can be cylindrical, such as a cylindrical shape, a square shape, a triangular shape, a polygonal shape, or a cylindrical structure with an arc 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 member 122 to ensure good sealing between the inner cavity 112 and the movable core 121 and the elastic sealing member 122. The insertion port 111 and the lead-out port 113 can be disposed on both sides of the inner cavity 112 along the first direction X. For example, they can be coaxially disposed on the connector 11 to meet the insertion requirement of the camera tube 20 along the first direction X, or vertically disposed, or obliquely disposed. The movable core 121 can be inserted or sleeved on the outer wall of the camera tube 20, with a clearance fit between them. In addition, there is a clearance fit between the movable core 121 and the 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 squeezes the elastic sealing member 122 by moving up and down, deforming it and fixing the camera tube 20.

[0075] The elastic seal 122 can be made of elastic materials, such as rubber, silicone material, etc., and can undergo elastic deformation under external pressure. The elastic seal 122 can be disposed below the movable core 121 along the first direction X. The elastic seal 122 is provided with a first sealing surface 122a on the side facing the camera tube 20, and the elastic seal 122 is provided with a second sealing surface 122b on the side facing the inner cavity 112. Both sealing surfaces can be sealing surfaces with a circular cross-section, a square cross-section, a polygonal cross-section, or a curved surface cross-section. The embodiments of the present application do not limit this. The first sealing surface 122a can seal a part of the outer peripheral surface of the camera tube 20, and the second sealing surface 122b can seal the space between the lower part of the inner cavity 112 and the movable core 121, specifically the space in the vicinity of the lead-out port 113 at the bottom of the inner cavity 112 and the space between the side wall of the inner cavity 112 and the camera tube 20. In the locked state, the elastic seal 122 can form a reliable seal to prevent external bacteria and viruses from entering.

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

[0077] As Figures 8 to 13 shown. During installation, the lock 13 is combined with the movable core 121 and / or the elastic seal 122. The elastic seal 122 and the movable core 121 are successively loaded into the inner cavity 112, and then the camera tube 20 is inserted into the inner holes of the movable core 121 and the elastic seal 122, and then passes through the lead-out port 113 of the joint 11. After the position is adjusted, the movable core 121 and the elastic seal 122 are fastened by the lock 13 so that the first sealing surface 122a fits the second sealing surface 122b.

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

[0079] Based on the cooperation between the movable core 121 and the elastic seal 122, and by using the lock 13 to control the up and down movement of the movable core 121 through closing and opening, the locking and unlocking functions are realized. The lock 13 provides a locking force or an unlocking force to the movable core 121, and the elastic seal 122 forms the fixation and sealing of the camera tube 20 after being deformed by the extrusion of the movable core 121.

[0080] The present application provides an endoscopic locking and sealing device 10 that can freely adjust the insertion depth and lock and seal the camera channel 40. Through the interaction of the movable core 121, the elastic seal 122, and the lock 13, the camera tube 20 can be fixed and sealed in the locked state, specifically as follows: The insertion part of the camera tube 20 is equipped with an elastic seal 122, and when the elastic seal 122 is in its natural state, it allows the camera tube 20 to pass through. When the lock 13 is closed, the movable core 121 moves downward, pressing down the elastic seal 122 to deform it. After the elastic seal 122 deforms, its first sealing surface 122a forms an interference fit with the outer diameter of the camera tube 20, and at the same time, the second sealing surface 122b of the elastic seal 122 also forms an interference fit with the inner wall of the cavity 112 of the joint 11, thereby achieving the fixation and sealing of the camera tube 20. In this way, the camera tube 20 can be freely inserted to any depth and fixed in the locked state, ensuring the sealing performance of the camera channel 40.

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

[0082] As Figure 4 shown. The first connecting member 1211 is provided on one side of the movable core 121 and is fixedly connected to the outer wall of the movable core 121. The first bottom surface 1211a is provided on the bottom surface of the first connecting member 1211, and it can be a flat surface, a curved surface, a serrated surface, a trapezoidal surface, etc. The second connecting member 114 is provided on one side of the joint 11 and is fixedly connected to the outer wall of the joint 11. The second connecting member 114 is disposed opposite to the first connecting member 1211, and the top surface 114a is provided on the side of the second connecting member 114 facing the movable core 121, that is, on the top surface of the second connecting member 114. The lock 13 is provided on the first connecting member 1211 and / or the second connecting member 114, and the two can be detachably connected, or rotatably connected, etc.

[0083] Under the locking force applied by the lock 13, the first bottom surface 1211a of the first connecting member 1211 can completely fit on the top of the second connecting member 114, so that the movable core 121 and the joint 11 are sealed, thereby improving the sealing performance between the movable core 121 and the joint 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 seal 122 facing the movable core 121, that is, the top surface of the movable core 121. The first sealing sub-surface 1221b is adapted to be attached to the second bottom surface 1211b of the movable core 121 under the action of the latch 13 and is sealed in contact with the second bottom surface 1211b of the movable core 121. The second sealing sub-surface 1222b is disposed on the circumferential surface of the elastic seal 122 and can be attached to the wall of the inner cavity 112 under the action of the latch 13 and is sealed with the inner cavity 112. The third sealing sub-surface 1223b is disposed on the bottom surface of the elastic seal 122 and can be attached to and sealed with the bottom surface 115 of the inner cavity under the action of the latch 13. Thus, a completely sealed structure can be formed between the movable core 121 and the elastic seal 122, and between the elastic seal 122 and the inner cavity 112.

[0085] Continue to refer to Figure 4 . The first sealing sub-surface 1221b is disposed on the top surface of the elastic seal 122. The area of the first sealing sub-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 orthographic projection of the first sealing sub-surface 1221b. Thus, under the action of the 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 along the circumference of the movable core body of the movable core 121, and the top surface 114a is distributed along the circumference of the sealing body of the elastic seal 122. Thus, a circumferential sealing structure surrounding the camera tube 20 is formed, which can improve the sealing efficiency and further enhance the sealing effect.

[0087] Regarding the connection manner of the latch 13, in a specific embodiment, the latch 13 is rotatably connected to the first connecting member 1211 or the second connecting member 114, for example, connected by a rotating shaft. The latch 13 is provided with a locking surface 135. The latch 13 rotates relative to the rotating shaft under an external force so that the locking surface 135 of the latch 13 locks the first connecting member 1211 and the second connecting member 114, thereby causing the movable core 121 to move downward and gradually squeezing the elastic seal 122 to deform it and seal the inner cavity 112 of the camera tube 20 and the joint 11. When the first connecting member 1211 contacts the second connecting member 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 is attached and sealed to the first sealing sub-surface 1221b, and the movable core 121 and the joint 11 achieve complete sealing. Thus, complete sealing between the components within the endoscope locking and sealing device 10 is achieved, thereby ensuring the sealing effect.

[0088] Regarding the structure of the latch 13, in the first specific embodiment, the latch 13 is rotatably connected to the second connecting member 114. The latch 13 includes a pressing portion 131, a first connecting portion 132, two second connecting portions 133, and two rotating portions 134. The two second connecting portions 133 are arranged oppositely. The first connecting portion 132 connects the pressing portion 131 and the two second connecting portions 133. The two rotating portions 134 are respectively fixed on the outer walls of the two second connecting portions 133. The locking surface 135 is arranged at the corner of the second connecting portion 133, and the length of the pressing portion 131 is greater than the lengths of the two second connecting portions 133.

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

[0090] In this way, a lever structure with the rotating portion 134 as the rotation center is formed. When the pressing portion 131 is pressed, under the action of the rotating portion 134, the pressing portion 131 drives the second connecting portion 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, when it continues to rotate, the locking surface 135 continuously presses against the second connecting member 114 and pushes the second connecting member 114 towards the first connecting member 1211, so as to push the movable core 121, the elastic locking member and the joint 11 to achieve sealing.

[0091] The above-mentioned 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. The convex surface can be arc-shaped, trapezoidal, serrated, etc. Compared with the inclined surface, the convex surface can reduce the rotation angle of the latch 13 and increase the thrust.

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

[0093] As Figures 19 to 25As shown in the figure. Specifically, the pressing part 131 has a pressing surface, on which an anti-slip structure can be provided to increase the contact friction with 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-plate structure, vertically connecting 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 is rotatably installed on the rotating connecting member of the joint 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 axis 14 of the first connecting member 1211. After that, when it continues to rotate, the locking surface 135 continuously presses against the axis 14 and achieves sealing with the axis 14.

[0095] In the third specific embodiment, the lock 13 is rotatably connected to the first connecting member 1211. The lock 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 provided on the pressing part 131, and the locking surface 135 is provided on the inner side surface of the second connecting part 133.

[0096] As Figures 27 to 32 shown in the figure. Specifically, the pressing part 131 has a pressing surface, on which an anti-slip structure can be provided to increase the contact friction with the hand. The first connecting part 132 can be plate-shaped or block-shaped, generally vertically connecting the pressing part 131 and the second connecting part 133. The second connecting part 133 is a plate-shaped or block-plate structure, and the locking surface 135 is provided on the inner side surface 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 is rotatably installed on the rotating connecting member of the movable core 121. The second connecting member 114 is provided with an axis 14, and the locking surface 135 is used to lock the axis 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, when it continues to rotate, the locking surface 135 continuously presses against the axis 14 and achieves sealing with the axis 14. Compared with the upward locking method used in the above second embodiment, the downward locking method adopted in this embodiment is affected by the self-weight of the lock 13, and the operation is more convenient and labor-saving, and the locking is more firm and reliable.

[0098] The above-mentioned lock 13 can be an integrally formed structure, which can ensure the connection strength, reduce the number of parts, and facilitate processing.

[0099] In summary, the embodiment of the present application provides an endoscope locking and sealing device 10. When the lock 13 is closed, the movable core 121 moves downward to press the elastic seal 122, causing the elastic seal 122 to deform and form an interference extrusion on the camera tube 20, thereby fixing the camera tube 20 and sealing the camera channel 40. In this way, it is possible to ensure that the camera tube 20 is fixed at a specific depth and sealed in the locked state, meeting the needs of clinical operations.

[0100] As Figure 1 and Figure 6 shown. In addition, the embodiment of the present application also provides an endoscope 100, including the above-mentioned endoscope locking and sealing device 10. The camera tube 20 is arranged in the camera channel 40, and the camera head 30 is plugged into the video connector 60 through the camera tube 20 and the plug 50, and finally connected to the display device 70.

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

[0102] The above has introduced in detail the endoscope and its endoscope locking and sealing device provided by the present application. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the present application.
