Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a damping component and an endoscope. Background Technology

[0002] During surgery, an endoscope is inserted into the patient's body for observation and treatment. Medical staff can rotate the insertion part of the endoscope relative to the handle to adjust its bending direction, lens angle, and avoid obstacles.

[0003] A damping element is installed at the rotational connection between the insertion part and the handle. The damping element provides controllable damping force for the rotation of the insertion part through the frictional resistance between itself and the rotating shaft and the assembly hole, so as to avoid the insertion part from rotating beyond the expected direction due to the inertia of the medical staff's hand operation and achieve fine rotation adjustment.

[0004] Existing technologies typically employ interference fit to fix the damping component to the insertion part or handle mounting hole, causing the damping component to elastically deform and generate a frictional damping effect. However, due to the need for interference fit, the damping component is difficult to assemble, has low assembly efficiency, and is prone to misalignment within the endoscope. Utility Model Content

[0005] In view of the shortcomings of the above-mentioned related technologies, this application provides a damping component and an endoscope to solve the above-mentioned technical problems.

[0006] This application provides a damping component for an endoscope. The damping component includes an elastic damping element and a connector. The connector is adapted to connect to the insertion part of the endoscope, and the elastic damping element is adapted to connect to the operating handle of the endoscope. The connector is movably connected to the elastic damping element. The connector is provided with a protrusion. A groove is formed on the surface of the elastic damping element near the connector. The protrusion is installed in the groove. During the movement of the connector relative to the elastic damping element, the protrusion can move out of the groove and press against the surface of the elastic damping element, causing the elastic damping element to deform and generating damping friction between the protrusion and the elastic damping element.

[0007] To achieve the above and other related objectives, this application provides an endoscope, which includes a damping member, an insertion part, and an operating handle as described above, with a connector connecting the insertion part and the elastic damping member mounted on the operating handle.

[0008] The technical solution adopted in this utility model achieves the following beneficial effects: During the movement of the connecting member relative to the elastic damping member, the protrusion can move out of the groove and press against the surface of the elastic damping member, causing deformation of the elastic damping member and generating damping friction between the protrusion and the elastic damping member. When the connecting member moves (e.g., rotates) relative to the elastic damping member, the protrusion gradually detaches from the groove and moves along the surface of the elastic damping member. As the connecting member rotates, the protrusion presses against the surface of the elastic damping member. Because the elastic damping member is elastic, it deforms after being pressed, and the reaction force generated by the deformation acts on the protrusion, generating frictional resistance between the protrusion and the surface of the elastic damping member, thus achieving the effect of damping friction. This provides appropriate resistance feedback for the movement, ensuring that the connecting member does not sway or rotate too quickly due to lack of resistance when moving relative to the elastic damping member, achieving a smooth and controllable rotation effect, and meeting the requirements for damping feel and stability during operation.

[0009] The groove and protrusion mating structure of this application eliminates the need for additional positioning tools during the assembly of the elastic damping component and the connecting component. The protrusion can quickly align and embed into the groove, simplifying the assembly process and accurately determining the initial relative position of the two components. This prevents misalignment or displacement during assembly, achieving convenient installation and accurate positioning. During assembly, the groove design reduces the compressive force between the elastic damping component and the connecting component, preventing interference and ensuring proper assembly.

[0010] Furthermore, during subsequent rotation, the protrusion can rotate into the groove, and the damping sensation caused by the friction between the protrusion and the elastic damping element will disappear. This change in damping sensation can be clearly fed back to the operator's hand, allowing the operator to clearly perceive that the protrusion has rotated into place, thereby achieving a distinct sense of segmentation and improving the accuracy and feel of operation.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0021] In the various embodiments of this application, "proximal end" and "far end" refer to the position of each component relative to the user in the usage environment. The end closer to the user is designated as the "proximal end", and the end farther from the user is designated as the "far end".

[0022] This application provides a damping member 100; please refer to [link / reference]. Figure 1 The damping member 100 can be used in the endoscope 1. The endoscope 1 includes an insertion part 200 and an operating handle 300. The operating handle 300 is connected to the proximal end of the insertion part 200. The insertion part 200 can be inserted into the body to collect image signals inside the human body, etc., without limitation.

[0023] Please see Figure 2 The damping member 100 may include an elastic damping element 110 and a connector 120. The connector 120 is adapted to connect to the insertion portion 200 of the endoscope 1. The connector 120 can drive the insertion portion 200 to rotate, thereby causing the insertion portion 200 to rotate within a human cavity or sheath, and rotating the insertion portion 200 to a predetermined angle. The elastic damping element 110 is adapted to connect to the operating handle 300 of the endoscope 1. Further, the elastic damping element 110 is fixed within the housing 320 of the operating handle 300, without limitation. The elastic damping element 110 is elastic and can be deformed by compression. The connector 120 is movably connected to the elastic damping element 110. Further, the elastic damping element 110 can be sleeved on the outside of the connector 120, or the connector 120 can be sleeved on the outside of the elastic damping element 110, without limitation.

[0024] Please see Figure 2 The connector 120 is provided with a protrusion 121, which protrudes from the surface of the connector 120 near the elastic damping member 110. A groove 111 is formed on the surface of the elastic damping member 110 near the connector 120, and the protrusion 121 is installed within the groove 111. During assembly, the protrusion 121 on the connector 120 can be installed within the groove 111. The groove 111 and the protrusion 121 are designed to cooperate, allowing the protrusion 121 to quickly align and embed into the groove 111 without the need for additional positioning tools during the assembly of the elastic damping member 110 and the connector 120. This simplifies the assembly process and accurately determines the initial relative position of the two components, preventing misalignment or displacement during assembly, thus achieving convenient installation and accurate positioning. During assembly, the groove 111 reduces the compressive force between the elastic damping member 110 and the connector 120, preventing interference between them and ensuring proper assembly.

[0025] Please see Figure 2During the movement of the connector 120 relative to the elastic damping member 110, the protrusion 121 can move out of the groove 111 and press against the surface of the elastic damping member 110, causing the elastic damping member 110 to deform and generating damping friction between the protrusion 121 and the elastic damping member 110. When the connector 120 moves relative to the elastic damping member 110, the protrusion 121 gradually detaches from the groove 111 and moves along the surface of the elastic damping member 110. As the connector 120 rotates, the protrusion 121 presses against the surface of the elastic damping member 110. Because the elastic damping member 110 is elastic, it deforms after being pressed, and the reaction force generated by the deformation acts on the protrusion 121, generating frictional resistance between the protrusion 121 and the surface of the elastic damping member 110, thus achieving the effect of damping friction. This provides appropriate resistance feedback for the movement, ensuring that the connector 120 will not wobble or rotate too quickly due to the lack of resistance when the relative elastic damping member 110 moves, thus achieving a smooth and controllable rotation effect and meeting the requirements for damping and stability during operation.

[0026] In one embodiment, the depth of the groove 111 is greater than or equal to the height of the protrusion 121. When the protrusion 121 moves within the groove 111, the groove depth is sufficient to accommodate the protrusion 121, ensuring no interference between the groove 111 and the protrusion 121 and guaranteeing assembly efficiency. Simultaneously, during the assembly of the damping member 100, the sufficient depth of the groove 111 provides ample space for the protrusion 121 to be inserted, allowing for easy embedding of the protrusion 121 into the groove 111 without precise alignment, greatly facilitating installation, reducing installation difficulty, and improving installation efficiency.

[0027] In another embodiment, the width of the groove 111 is greater than or equal to the width of the protrusion 121. For example, the width of the groove 111 is 1 to 1.5 times that of the protrusion 121, such as 1, 1.25, or 1.5 times, and is not limited. This ensures that the protrusion 121 has sufficient installation space 133 along its width within the groove 111, preventing excessive compression against the side walls of the groove 111. This ensures that the resistance generated between the groove wall of the groove 111 and the protrusion 121 prevents any jamming during relative movement. Furthermore, when installing the damping member 100, a wider groove 111 allows the protrusion 121 to be adjusted within a certain range, reducing the assembly difficulty of fitting the protrusion 121 into the groove 111, facilitating quick insertion of the protrusion 121 into the groove 111, and simplifying the installation process.

[0028] In addition, in some other cases, the width of the groove 111 is greater than or equal to the width of the protrusion 121, and the depth of the groove 111 is greater than or equal to the height of the protrusion 121, which further facilitates the installation operation, and will not be elaborated here.

[0029] In the embodiments of this application, please refer to Figure 3 The number of grooves 111 can be multiple, such as 2, 3, or even more, without limitation. Multiple grooves 111 are spaced apart along the movement path of the protrusion 121. When the connector 120 drives the protrusion 121 to rotate, the protrusion 121 can sequentially enter different grooves 111, engaging with them. This allows the protrusion 121 to rotate to multiple different angles and stabilize in the corresponding positions. For example, multiple grooves 111 can be spaced apart circumferentially along the elastic damping member 110. When the protrusion 121 rotates into position and engages in a groove 111, the damping sensation caused by friction between the protrusion 121 and the elastic damping member 110 disappears. This change in damping sensation is clearly fed back to the operator's hand, allowing the operator to clearly perceive that the protrusion 121 has rotated into position, thus achieving a distinct tactile feedback and improving operational accuracy and feel.

[0030] In other cases, the number of protrusions 121 can be multiple, such as two, three, or even more, without limitation. Multiple protrusions 121 are distributed circumferentially around the connector 120, and can simultaneously abut against the elastic damping member 110 to balance the force between the elastic damping member 110 and the connector 120, avoiding the accumulation of internal forces that could cause the elastic damping member 110 to twist and break.

[0031] In the embodiments of this application, please refer to Figure 4 The connector 120 is rotatably mounted at the opening 310 of the operating handle 300. A rotating groove is formed on the outer periphery of the connector 120, and the inner wall of the opening 310 is embedded in the rotating groove, allowing the connector 120 to rotate around the central axis of the opening 310. The groove wall of the rotating groove abuts against the operating handle 300 along the axial direction of the opening 310. The two side walls of the rotating groove abut against the operating handle 300 along the axial direction of the opening 310. In the radial direction, the inner wall of the operating handle 300 embedded in the rotating groove restricts the radial movement of the connector 120. In the axial direction, the groove wall of the rotating groove abuts against the operating handle 300, restricting the axial movement of the connector 120. Through this dual radial and axial restraint, the connector 120 can rotate stably at the opening 310 of the operating handle 300 without radial offset or axial movement, ensuring the stability of the rotational fit between the connector 120 and the operating handle 300.

[0032] Please see Figure 3 as well as Figure 4The outer periphery of the connector 120 may be provided with a stop portion 122, which abuts against the wall forming the opening 310 to restrict the movement of the connector 120. When the connector 120 drives the stop portion 122 to rotate, as the rotation angle increases, the stop portion 122 will gradually approach the wall forming the opening 310. When it rotates to a certain angle, the stop portion 122 will completely abut against the wall forming the opening 310, at which point the connector 120 can no longer rotate. The effect of this arrangement is that the abutment action between the stop portion 122 and the wall of the opening 310 limits the maximum rotation angle of the connector 120, preventing the connector 120 from exceeding its range due to excessive rotation, and preventing damage to the internal structure of the damping component 100 or affecting the normal operation of the overall equipment due to excessive rotation. In addition, the operating handle 300 has a housing 320, which may include an upper housing and a lower housing. After the damping member 100 is assembled, the damping member 100 is placed into the lower housing, and then the upper housing is fastened to the lower housing, thus completing the assembly of the operating handle 300 and the fixing of the connector 120 in the operating handle 300.

[0033] The elastic damping element 110 may deform excessively, causing it to separate from the connecting element 120, resulting in the damping member 100 losing its damping effect. In the embodiments of this application, please refer to... Figure 2 as well as Figure 5 The damping member 100 may further include a mounting member 130, which connects to the elastic damping member 110. The elastic damping member 110 is mounted on the operating handle 300 via the mounting member 130. The elastic damping member 110 is located between the connecting member 120 and the mounting member 130, and the mounting member 130 can abut against the surface of the elastic damping member 110 away from the connecting member 120. The presence of the mounting member 130 provides stable support for the elastic damping member 110, preventing the excessively deformed elastic damping member 110 from collapsing under stress due to insufficient support while only contacting the connecting member 120. At the same time, the supporting effect of the mounting member 130 ensures that the elastic damping member 110 always maintains a stable fit with the connecting member 120, preventing a loose fit due to the collapse of the elastic damping member 110, and ensuring stable damping between the elastic damping member 110 and the connecting member 120.

[0034] Please see Figure 6The elastic damping element 110 can be a hollow ring structure. One of the mounting element 130 and the connecting element 120 is sleeved on the outside of the elastic damping element 110, while the other is disposed inside the elastic damping element 110 and abuts against the inner surface of the elastic damping element 110. The mounting element 130 can stabilize the elastic damping element 110 in a preset position. At the same time, the mounting element 130 is fixed on the operating handle 300 through its connection with the operating handle 300, thereby driving the elastic damping element 110 to be stably installed. This structure not only ensures the positional stability of the elastic damping element 110, but also allows the elastic damping element 110 to fully contact the connecting element 120, ensuring the effective transmission of damping friction force.

[0035] Please refer to the previous document. Figure 2 The outer periphery of the mounting member 130 has an abutment surface 131, which can be a plane or a curved surface, etc., and is not limited thereto. The abutment surface 131 is adapted to abut against the operating handle 300 to fix the mounting member 130 within the operating handle 300. For example, when the mounting member 130 is installed into the operating handle 300, the abutment surface 131 will form a tight abutment with the operating handle 300. Through the friction and limiting effect generated by the abutment, the movement or rotation of the mounting member 130 within the operating handle 300 is restricted. The effect of this arrangement is that the mounting member 130 can be completely fixed to the operating handle 300, and there will be no loosening or displacement of the mounting member 130. This provides a basis for the stable cooperation between the elastic damping member 110 and the connecting member 120, and ensures the structural stability of the damping member 100.

[0036] The end face of the elastic damping element 110 abuts against the mounting member 130, or the end face of the elastic damping element 110 is in a free state. Here, "free state" means that the end face of the elastic damping element 110 is not in contact with any other component. For example, when the end face of the elastic damping element 110 abuts against the mounting member 130, the mounting member 130 limits the end face of the elastic damping element 110, keeping the elastic damping element 110 and the mounting member 130 relatively fixed and preventing relative displacement. Furthermore, this prevents the end face of the elastic damping element 110 from being driven by the connecting member 120 when the connecting member 120 rotates, thus avoiding overall twisting of the elastic damping element 110. This ensures that the elastic damping element 110 always maintains its original shape and structure, ensuring the stability of the damping performance of the elastic damping element 110 and the connecting member 120, and preventing damping failure due to twisting.

[0037] In the embodiments of this application, please refer to Figure 2The elastic damping element 110 has a protruding connecting portion 112 on its surface near the mounting member 130. The mounting member 130 has an assembly groove 132, and the connecting portion 112 is fixedly installed in the assembly groove 132, so that the elastic damping element 110 and the mounting member 130 are in a limiting fit. The fixed fit between the connecting portion 112 and the assembly groove 132 can restrict the relative movement and rotation between the elastic damping element 110 and the mounting member 130, and achieve relative fixation between the two. This fixing method is simple and stable, and can ensure that the elastic damping element 110 will not shift or fall off relative to the mounting member 130 during the use of the damping member 100, ensuring that the elastic damping element 110 is always in the correct working position and stably exerts its damping effect.

[0038] Preferably, please refer to Figure 2 The connecting part 112 and the groove 111 are provided in a corresponding manner in the circumferential direction of the elastic damping member 110, that is, the connecting part 112 and the groove 111 are on the same radial direction of the elastic damping member 110. This can improve the structural strength of the groove 111 through the connecting part 112 and avoid the reduction of strength of the elastic damping member 110 due to the groove 111.

[0039] In a more specific embodiment, the mounting member 130 can be a hollow columnar structure. The mounting member 130 is suitable for fixed installation within the operating handle 300. The elastic damping member 110 is installed within the mounting member 130 and conforms to the inner wall of the mounting member 130. The connecting member 120 is disposed within the elastic damping member 110, with a protrusion 121 abutting against the inner wall of the elastic damping member 110. The hollow columnar mounting member 130 provides an installation space 133 for the elastic damping member 110 and the connecting member 120, ensuring stable assembly of each component. The elastic damping member 110 conforms to the inner wall of the mounting member 130, providing support and preventing collapse of the elastic damping member 110. The connector 120 is located inside the elastic damping member 110. Its protrusion 121 abuts against the inner wall of the elastic damping member 110. When the connector 120 rotates, frictional damping is generated between the protrusion 121 and the elastic damping member 110, thereby realizing the damping cooperation between the elastic damping member 110 and the connector 120 and ensuring its damping effect.

[0040] In the embodiments of this application, please refer to Figure 5The inner wall of the mounting component 130 is provided with a mounting groove 134, and the assembly groove 132 communicates with the mounting groove 134. The connector 120 presses the elastic damping component 110 against the mounting groove 134, with the opposite ends of the elastic damping component 110 abutting against the groove wall forming the mounting groove 134. This arrangement ensures that the elastic damping component 110 is completely confined within the mounting groove 134, and its two ends are limited by the groove wall of the mounting groove 134, preventing displacement or twisting caused by the connecting part 112 when the connector 120 rotates or is subjected to force. At the same time, the communication between the mounting groove 134 and the assembly groove 132 ensures that the connecting part 112 is stably installed within the assembly groove 132, improving the protective capability of the elastic damping component 110, further enhancing the stability of the elastic damping component 110, avoiding structural failures caused by the movement of the elastic damping component 110, and ensuring safety during use.

[0041] In the embodiments of this application, please refer to Figure 2 The connector 120 is provided with a slider 123, which is movably disposed relative to the mounting member 130. The mounting member 130 and / or the elastic damping member 110 are provided with a limiting portion located in the movement path of the slider 123, which limits the rotation range of the connector 120. Furthermore, at least one of the mounting member 130 and the elastic damping member 110 has a limiting portion on its outer wall. When the slider 123 moves with the connector 120, it can move along a preset path. When the slider 123 moves to the limiting portion, the limiting portion blocks the slider 123 from continuing to move, thereby limiting the rotation of the connector 120. The effect of this arrangement is that by blocking the slider 123 with the limiting portion, the rotation range of the connector 120 is limited, preventing the connector 120 from exceeding the load-bearing capacity of the endoscope 1 due to excessive rotation, preventing damage to the internal structure of the endoscope 1 due to excessive rotation, and ensuring the normal use of the endoscope 1.

[0042] In one embodiment, when the slider 123 moves to a predetermined position, it abuts against the housing 320 of the operating handle 300 to limit the rotation range of the connector 120. When the slider 123 reaches the predetermined position, the abutment between the slider 123 and the housing 320 generates a blocking force, preventing the connector 120 from continuing to rotate. This arrangement further limits the rotation range of the connector 120 by the abutment between the slider 123 and the housing 320, preventing excessive rotation of the connector 120 and potential damage to the endoscope 1, thus ensuring the safety and stability of the endoscope 1 during operation.

[0043] In the embodiments of this application, please refer to Figure 6The damping component 100 may further include a fastener 140 and an assembly 150. The assembly 150 has a mounting hole, through which a fastener passes and is threadedly connected to the connector 120. The fastener 140 can fasten the assembly 150 and cover the mounting hole and the fastener. This design allows the fastener 140 to enclose the mounting hole and the fastener, preventing the fastener from loosening and falling off after long-term use due to exposed threads, thus improving the structural stability of the entire damping component 100. At the same time, the covering effect of the fastener 140 also serves to prevent disassembly, preventing unauthorized personnel from arbitrarily disassembling the fasteners and causing structural damage, thus ensuring the normal operation of the damping component 100.

[0044] In one embodiment, the damping member 100 may further be provided with an abutment member, which is installed within the assembly 150 and elastically abuts against the fastener and the fastener 140. The abutment member is elastic; when the fastener 140 is fastened onto the assembly 150, the abutment member will undergo elastic deformation due to the compression of the fastener and the fastener 140. The elastic force generated by this deformation will act on both the fastener and the fastener 140, maintaining a certain buffer space between them. The effect of this arrangement is that, through the elastic buffering effect of the abutment member, direct hard compression between the fastener and the fastener 140 is avoided, preventing deformation due to excessive compression force, ensuring the structural integrity of the assembly 150 and the fastener 140, and extending the service life of the damping member 100.

[0045] To achieve the above and other related objectives, this application provides an endoscope 1. Please refer to [link to application]. Figure 1 The endoscope 1 includes the damping member 100, the insertion part 200, and the operating handle 300 as described above. A connector 120 connects to the insertion part 200, and an elastic damping member 110 is mounted on the operating handle 300. This gives the negative pressure suction assembly the beneficial effects of any of the aforementioned solutions, which will not be elaborated further here. The endoscope 1 can be a bronchoscope, pyeloscope, esophagoscope, gastroscope, colonoscope, otoscope, rhinoscope, oral endoscope, laryngoscope, colposcope, laparoscope, arthroscope, etc. This application does not specifically limit the type of endoscope 1.

[0046] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0047] Furthermore, it should be noted that the scope of the methods and apparatus in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing functions substantially simultaneously or in the reverse order, depending on the functions involved. For example, the described methods may be performed in a different order than 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.

[0048] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
