Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an elastic protective sleeve, an operating handle, and an endoscope. Background Technology

[0002] An endoscope is a commonly used medical device that can directly enter human cavities for examination, providing doctors with comprehensive diagnostic information. An endoscope typically includes: an insertion part for insertion into the body, a handle for controlling the bending of the insertion part's tip, and a display device for showing the internal environment of the body's natural cavities. Through the coordination of these three parts, an endoscope can achieve visualization of the human body's interior, exploration of lesions, and treatment.

[0003] In related technologies, the endoscope handle is connected to the proximal end of the insertion part, and the bending of the insertion part can be controlled by operating the operating components on the handle; the handle is also connected to a connecting cable, and the other end of the connecting cable is connected to a display device, so that the image information collected by the insertion part can be displayed on the display device.

[0004] When the cable extends out of the operating handle's housing, it is prone to bending and breakage. Existing operating handles often have protective sleeves to protect the cable. However, existing protective sleeves are ineffective at protecting the cable, and may even detach from the housing or cause the cable to break. Utility Model Content

[0005] In view of the shortcomings of the above-mentioned related technologies, this application provides an elastic protective sleeve, an operating handle, and an endoscope to solve the above-mentioned technical problems.

[0006] In a first aspect, this application provides an elastic protective sleeve for the operating handle of an endoscope. The elastic protective sleeve is adapted to be installed on the housing of the operating handle. The elastic protective sleeve includes a first connecting part and a second connecting part. The first connecting part has a first channel that extends through the first connecting part and is adapted to install the insertion part of the endoscope. The first connecting part is provided with a first mounting structure. The second connecting part is connected to the first connecting part and has a second channel that extends through the second connecting part and is adapted to install a cable led out from the operating handle. The second connecting part is provided with a second mounting structure. The first mounting structure and the second mounting structure are both fixedly connected to the housing and are arranged in a staggered manner along the axial direction of the first channel.

[0007] Secondly, this application provides an operating handle, including a housing and an elastic protective sleeve as described above, a first mounting structure and a second mounting structure are mounted on the housing, and a cable leading out from the operating handle is mounted on a second channel.

[0008] Thirdly, this application provides an endoscope, characterized in that it includes an operating handle and an insertion part as described above, the insertion part being installed in a first channel.

[0009] The technical solution adopted in this utility model achieves the following beneficial effects: the first channel of the first connecting part can be used to install the insertion part of the endoscope, and the second channel of the second connecting part can be used to install the cable of the endoscope. The second connecting part is connected to the first connecting part, and both the first mounting structure of the first connecting part and the second mounting structure of the second connecting part can be mounted on the housing, ensuring that the elastic protective sleeve can be stably mounted on the housing. In addition, the first mounting structure and the second mounting structure are staggered in the axial direction of the first channel. The staggered arrangement allows the first mounting structure and the second mounting structure to be relatively far apart in the axial direction, and the force will be continuously dispersed during the transmission between the first mounting structure and the second mounting structure, avoiding excessive deformation caused by the simultaneous application of force to both, which can prevent the elastic protective sleeve from detaching from the housing and improve the safety of the endoscope. For example, when the insertion part or the first connecting part is subjected to external force, the second connecting part will not be directly driven to deform. The external force will be transmitted along the axial direction of the first connecting part and gradually to the first mounting structure and the corresponding part of the housing, and only then may it be transmitted to the second connecting part. During transmission, the external force is absorbed by the first connector and its corresponding portion of the housing. The effect of the force is reduced by the time it reaches the second connector, making it difficult to force significant deformation of the second connector and the cable. Conversely, while the cable or the second connector is subjected to external force, the first connector and the insertion part are not directly driven to undergo significant deformation. This prevents the elastic protective sleeve from being pulled by external force, thus ensuring that the elastic protective sleeve cannot easily detach from the housing.

[0010] Furthermore, compared to radial misalignment, when one of the cable and the insertion part is subjected to an external force acting radially, because the first mounting structure and the second mounting structure of this application are axially misaligned, the radial force will not be directly transmitted from one to the other, and the two will not deform radially at the same time. This can prevent the first mounting structure and the second mounting structure from deforming simultaneously and falling off. Attached Figure Description

[0021] 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.

[0022] 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.

[0023] In the various embodiments of this application, "near end" and "far end" refer to the distance of each component from the user in the usage environment. The end closer to the user is designated as the "near end", and the end farther from the user is designated as the "far end".

[0024] This application provides an elastic protective sleeve 110; please refer to [link / reference]. Figure 1 The elastic protective sleeve 110 is used for the operating handle 100 of the endoscope 1. The endoscope 1 also includes an insertion part 200, which is connected to the operating handle 100. The insertion part 200 can be inserted into the patient's body. Medical personnel operate the operating handle 100 to control the insertion, bending, or aspiration of the media by the insertion part 200, without limiting the function or type of the endoscope 1.

[0025] Please see Figure 1 as well as Figure 2 The elastic protective sleeve 110 is adapted to be installed on the housing 120 of the operating handle 100. The elastic protective sleeve 110 may include a first connecting part 111 and a second connecting part 112, which are connected together.

[0026] Please see Figure 3 The first connecting portion 111 has a first channel 1111 extending through it, and is suitable for installing the insertion portion 200 of the endoscope 1. The second connecting portion 112 has a second channel 1121 extending through it, and is suitable for installing the cable 300 extending from the operating handle 100. The first connecting portion 111 provides protection for the insertion portion 200, preventing bending or other damage. The second connecting portion 112 provides protection for the cable 300, preventing bending or other damage. The cable 300 can transmit signals or power, and can be a power cable, a signal transmission cable, or a combination of both; the type and specifications of the cable 300 are not limited. In some cases, the cable 300 can be an optical fiber or a combination of optical fiber and metal wire.

[0027] Please continue reading. Figure 3 The first connecting part 111 is provided with a first mounting structure 1112, and the second connecting part 112 is provided with a second mounting structure 1122. The first mounting structure 1112 of the first connecting part 111 and the second mounting structure 1122 of the second connecting part 112 can both be mounted on the housing 120 to ensure that the elastic protective sleeve 110 can be stably mounted on the housing 120.

[0028] Please see Figure 3 as well as Figure 4 The first mounting structure 1112 and the second mounting structure 1122 are staggered along the axial direction of the first channel 1111. This staggered arrangement allows the first mounting structure 1112 and the second mounting structure 1122 to be relatively far apart along the axial direction. This prevents the elastic protective sleeve 110 from detaching from the housing 120, improving the safety of the endoscope 1. For example, when the insertion part 200 or the first connecting part 111 is subjected to an external force, the second connecting part 112 will not be directly driven to deform. The external force will be transmitted along the axial direction of the first connecting part 111 and gradually to the first mounting structure 1112 and the corresponding part of the housing 120, and only then may it be transmitted to the second connecting part 112. During the transmission process, the external force will be absorbed by the first connecting part 111 and its corresponding part of the housing 120. The effect of the external force when it is transmitted to the second connecting part 112 has decreased, making it difficult to force the second connecting part 112 and the cable 300 to undergo significant deformation. Conversely, when the cable 300 or the second connecting part 112 is subjected to external force, the first connecting part 111 and the insertion part 200 will not be directly driven and deformed significantly. This prevents the elastic protective sleeve 110 from being pulled by external force and causing overall deformation, ensuring that the elastic protective sleeve 110 cannot easily detach from the housing 120.

[0029] Furthermore, compared to radial misalignment, when one of the cable 300 and the insertion part 200 is subjected to an external force acting radially, because the first mounting structure 1112 and the second mounting structure 1122 of this application are axially misaligned, the radial force will not be directly transmitted from one to the other, and the two will not deform radially at the same time. This can prevent the first mounting structure 1112 and the second mounting structure 1122 from deforming simultaneously and falling off.

[0030] In a more specific implementation, please refer again. Figure 3The shape and specifications of the first mounting structure 1112 are adapted to the corresponding portion of the housing 120. For example, the first mounting structure 1112 has an annular groove that engages with an annular protrusion within the housing 120. Through radial and axial limiting effects, the position of the first connecting portion 111 within the housing 120 is fixed, preventing sliding or circumferential rotation along the axis of the first connecting portion 111. The proximal end of the first mounting structure 1112 connects to the second connecting portion 112, which also provides a limiting effect for the second connecting portion 112, preventing it from detaching from the housing 120 and improving safety.

[0031] In the embodiments of this application, please refer to Figure 3 In the axial direction of the first channel 1111, the second connecting portion 112 is located near the proximal end of the first mounting structure 1112. This arrangement avoids the first connecting portion 111 and the second connecting portion 112 being subjected to force in the same axial position, reducing the probability of damage. Simultaneously, this increases the force propagation path length, providing a larger force-sharing area for the soft rubber. That is, the external force is gradually transmitted to the first mounting structure 1112 and the corresponding portion of the housing 120 before potentially reaching the second connecting portion 112. The force is only received by the second connecting portion 112 and its second mounting structure 1122 after being absorbed by the first mounting structure 1112 and the housing 120. The second connecting portion 112 as a whole receives this force, distributing it throughout the second connecting portion 112 and not limiting it to the second mounting structure 1122. This prevents excessive deformation of the second mounting structure 1122, avoids the elastic protective sleeve 110 detaching from the housing 120, and improves the structural stability of the operating handle 100.

[0032] In one embodiment, the second connecting portion 112 is provided with a positioning structure 1124, which connects to the proximal end of the first mounting structure 1112 and can mutually limit the positioning of the housing 120. The positioning structure 1124 can be a recess, a groove, or a threaded hole. For example, when the positioning structure 1124 is an annular boss, it cooperates with the positioning groove in the endoscope housing 120 to achieve the positioning of the second connecting portion 112. At the same time, because the positioning structure 1124 is connected to the first mounting structure 1112, it can also achieve the positioning between the first connecting portion 111 and the housing 120. The positioning structure 1124 allows the first connecting portion 111 and the second connecting portion 112 to be quickly installed to the preset position of the housing 120 during installation, reducing assembly errors. At the same time, during operation, the positioning structure 1124 prevents the second connecting portion 112 from disengaging due to vibration, ensuring the relative position between the second connecting portion 112 and the housing 120 is stable.

[0033] For further details, please refer to Figure 3 as well as Figure 5The first mounting structure 1112 may include a first part 1113 and a second part 1114 that are connected to each other. The first part 1113 and the second part 1114 are connected and form a first channel 1111. For example, the cross-section of the first part 1113 and the second part 1114 may each be two semi-circular rings, and the first part 1113 and the second part 1114 may be integrally formed to form a hollow cylindrical structure.

[0034] The positioning structure 1124 is connected to the proximal end of the first portion 1113 and is located on one side of the axis of the first channel 1111. In other words, the positioning structure 1124 is not connected to the second portion 1114, and is located on the side of the axis of the first channel 1111 closer to the first portion 1113. The force between the first connecting portion 111 and the second connecting portion 112 is transmitted through the first portion 1113 and the positioning structure 1124. When an external force drives the second connecting portion 112 to move away from the axis of the first channel 1111, the positioning structure 1124 can deform to buffer the external force. At the same time, except that the positioning structure 1124 only covers a part of the insertion portion 200, the insertion portion 200 does not obstruct the movement of the positioning structure 1124 away from the axis of the first channel 1111, which ensures that the external force is not directly transmitted to the first connecting portion 111. This configuration also provides greater deformation space for the positioning structure 1124, thereby buffering the impact force and preventing structural damage to the insertion part 200, while ensuring that the axial position of the first channel 1111 remains stable and does not affect the normal operation of the insertion part 200 and its components.

[0035] Please see Figure 3 The distal end of the second connecting portion 112 is provided with a socket portion 1123, which can be a hollow tubular structure. Furthermore, the socket portion 1123 can be a hollow structure, and it communicates with the second channel 1121. The socket portion 1123 provides elastic support for the cable 300, preventing bending. The inner wall of the socket portion 1123 is provided with anti-slip textures, ensuring that the socket portion 1123 and the cable 300 do not loosen or separate, maintaining the continuity of force transmission.

[0036] Preferably, the first connecting portion 111 and the second connecting portion 112 are integrally formed. Furthermore, the first connecting portion 111 and the second connecting portion 112 can be integrally injection molded or ultrasonically welded, and there is no limitation thereto. This arrangement can improve the structural strength and fatigue resistance of the elastic protective sleeve 110, preventing the elastic protective sleeve 110 from loosening and failing due to external impact. The integrally formed structure also simplifies the assembly process, reduces the number of parts in the elastic protective sleeve 110, reduces production errors, and facilitates overall disassembly and replacement during later maintenance, improving the maintainability of the equipment.

[0037] In addition, the elastic protective sleeve 110 is elastic, and both the first connecting part 111 and the second connecting part 112 can be made of flexible materials and are elastic. This can buffer the impact of external forces and improve the protective capability of the elastic protective sleeve 110.

[0038] To achieve the above and other related objectives, this application provides an operating handle 100. Please refer to [link / reference]. Figure 1 The operating handle 100 includes a housing 120 and an elastic protective sleeve 110 as described above. A first mounting structure 1112 and a second mounting structure 1122 are mounted on the housing 120, and a cable 300 extending from the operating handle 100 is mounted on a second channel 1121. This gives the operating handle 100 the beneficial effects of any of the aforementioned solutions, which will not be elaborated further here.

[0039] Please see Figure 6 The housing 120 may include a housing body 121 and a cable mounting portion 122. The distal end of the housing body 121 has an insertion mounting portion 1211. The cable mounting portion 122 is disposed on the side of the housing body 121, and the radial projection of the cable mounting portion 122 along the housing body 121 is located on the proximal side of the insertion mounting portion 1211. The cable mounting portion 122 is located on the side of the housing body 121, and its radial projection falls on the proximal side of the insertion mounting portion 1211, forming a staggered distribution along the central axis of the housing 120. A first connecting portion 111 is installed inside the cable mounting portion 122, and a second connecting portion 112 is fixed to the insertion mounting portion 1211; the two are axially spaced apart.

[0040] Please see Figure 2 as well as Figure 7 The first mounting structure 1112 is mounted on the insertion mounting portion 1211, and the second mounting structure 1122 is mounted on the cable mounting portion 122, so that the first mounting structure 1112 and the second mounting structure 1122 are staggered along the central axis of the housing 120. This staggered arrangement allows the external force on the first mounting structure 1112 to be independently transmitted through the insertion mounting portion 1211, while the external force on the second mounting structure 1122 is directly transmitted to the housing body 121 through the cable mounting portion 122, and the force transmission paths of the two are independent of each other. For example, when an external force pulls the second connecting portion 112, the force is transmitted through the side wall of the second mounting structure 1122 to the cable mounting portion 122, and then to the housing body 121, avoiding the direct transmission of force to the first connecting portion 111, which could cause excessive deformation of the first connecting portion 111 or the insertion portion 200, reducing the risk of the elastic protective sleeve 110 falling off, and improving the structural stability of the operating handle 100.

[0041] In one implementation, please refer to Figure 8The housing body 121 may include a first housing 1212 and a second housing 1213, which are interconnected. The first housing 1212 and the second housing 1213 can be connected by screws, clips, or welding, without limitation. A first mounting space 123 is formed between the first housing 1212 and the second housing 1213. A cable mounting part 122 is disposed on the second housing 1213, and a first mounting structure 1112 is mounted on the first mounting space 123. The cable mounting part 122 has a second mounting space 1221, and the second mounting structure 1122 is mounted on the second mounting space 1221. The first mounting space 123 and the second mounting space 1221 are interconnected through a cable channel 1213. A portion of the first mounting structure 1112 is mounted within the cable channel 1213, and the first mounting structure 1112 is fitted with the channel wall forming the cable channel 1213. For example, the cable channel 1213 may be a strip-shaped groove extending axially along the second housing 1213. The first mounting structure 1112 has a raised structure on its side, the shape and size of which are adapted to the wire groove 1213. The raised structure of the first connecting part 111 is embedded in the wire groove 1213, and the raised structure and the wire groove 1213 form a circumferential limiting fit, restricting the first connecting part 111 from rotating circumferentially. In addition, the first connecting part 111 and the second connecting part 112 are connected, and the mutual adaptation of the first mounting structure 1112 and the wire groove 1213 can restrict the second connecting part 112 from rotating circumferentially.

[0042] 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 aforementioned operating handle 100 and insertion part 200, with the insertion part 200 installed in the first channel 1111. This gives the endoscope 1 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.

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.

[0044] 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.
