Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a connector mounting structure, an operating handle, and an endoscope. Background Technology

[0002] An endoscope is a commonly used medical device that can directly enter the body's natural passages, providing doctors with ample diagnostic information for disease treatment. The endoscope's handle includes connectors, such as a three-way connector. One end of the three-way connector connects to the insertion section, while the other two connect to the suction pump and instrument tubing, respectively, for inserting instruments and aspirating media.

[0003] To ensure the stability of the connection between the connector and adjacent pipes or handles, and to prevent loosening, displacement, or even detachment due to fluid pressure, vibration, or external forces, a separate fixing structure is often required on the handle. However, the assembly of the fixing structure and the connector increases the difficulty of connector installation, leading to reduced assembly efficiency. Utility Model Content

[0004] In view of the shortcomings of the above-mentioned related technologies, this application provides a connector mounting structure, an operating handle, and an endoscope to solve the above-mentioned technical problems.

[0005] This application provides a connector mounting structure for an endoscope. The mounting structure includes a housing and a connector. The housing has a first mounting portion and a second mounting portion. The connector includes a main pipe and a branch pipe connected together. The main pipe has a main channel, and the branch pipe has a branch channel connected to the main channel. The extension directions of the main pipe and the branch pipe intersect. The main pipe is embedded in the first mounting portion, and the branch pipe is embedded in the second mounting portion.

[0006] To achieve the above and other related objectives, this application provides an operating handle, including the aforementioned mounting structure.

[0007] To achieve the above and other related objectives, this application provides an endoscope including the aforementioned operating handle.

[0008] The technical solution adopted in this utility model achieves the following beneficial effects: While the main pipe is embedded in the first mounting part, the branch pipe is embedded in the second mounting part. The main pipe and branch pipe of the mounting structure are interconnected. The extension directions of the main pipe and branch pipe intersect. The first mounting part restricts and constrains the main pipe, and the second mounting part restricts and constrains the branch pipe. This results in the shell's constraint directions on the main pipe and branch pipe intersecting, meaning the shell's constraint effects on the main pipe and branch pipe are mutually cross-functional. Thus, the entire connector is completely constrained by the shell's action. Specifically, the first mounting part provides a radial constraint force on the main pipe, restricting the main pipe from moving radially. The constraint force of the first mounting part on the main pipe provides circumferential and axial constraints on the branch pipe, restricting the branch pipe from rotating or moving around its own axis. The second mounting section provides radial constraint on the branch pipe, restricting its movement in its radial direction. The first mounting section's constraint on the main pipe can also be addressed by the second mounting section providing circumferential and axial constraint on the main pipe, restricting its rotation or movement around its axis. The combined constraint forces on the same connector enable complete positioning and installation of the connector on the housing. Furthermore, the housing does not require a separate fixing structure, thus achieving stable connector installation, reducing installation difficulty, and improving assembly efficiency.

[0018] 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.

[0019] 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.

[0020] 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".

[0021] Often, a separate fixing structure needs to be installed on the handle. The existing method for installing handle connectors involves fixing the end of the main pipe or branch of the connector to the handle housing. However, fixing the connector only at the end is unstable, causing it to wobble inside the handle. Therefore, a separate fixing structure is needed inside the handle. However, the assembly of the fixing structure and the connector increases the difficulty of connector installation, leading to reduced assembly efficiency.

[0022] This application provides a connector mounting structure 100, hereinafter referred to as mounting structure 100. Please refer to [link to relevant documentation]. Figure 1 The mounting structure 100 is used for the endoscope 2. Furthermore, the mounting structure 100 is used for the operating handle 1 of the endoscope 2, and the connector 110 can connect to the insertion portion of the endoscope 2.

[0023] Mounting structure 100 may include housing 120 and connector 110, with connector 110 mounted on housing 120.

[0024] Please continue reading. Figure 1 The housing 120 can be the outer shell of the operating handle 1. The housing 120 has a first mounting portion 125 and a second mounting portion 126. The first mounting portion 125 and the second mounting portion 126 can be wall panels or ribs at two different locations on the housing 120, and are not limited thereto. Furthermore, both the first mounting portion 125 and the second mounting portion 126 can be provided with mounting holes for the connector 110 to be installed.

[0025] Please see Figure 2 The connector 110 includes a main pipe 111 and a branch pipe 112. The main pipe 111 has a main channel, and the branch pipe 112 has a branch channel connected to the main channel. The main channel can be used to insert instruments, such as biopsy forceps or lasers. The branch channel can be connected to a negative pressure suction pump for negative pressure suction. The main channel and the branch channel are interconnected and communicate with the instrument channel of the insertion part to insert instruments into the insertion part or to transfer the negative pressure suction to the distal end of the insertion part. Of course, in other cases, the main channel can be connected to a negative pressure suction pump, and the branch channel can be used to insert instruments, which will not be elaborated further.

[0026] Please see Figure 3The main pipe 111 and the branch pipe 112 extend in intersecting directions. The main pipe 111 is embedded in the first mounting part 125, and the branch pipe 112 is embedded in the second mounting part 126. The main pipe 111 and the branch pipe 112 of the mounting structure 100 are interconnected. The intersecting extension directions of the main pipe 111 and the branch pipe 112, the constraint imposed by the first mounting part 125 on the main pipe, and the constraint imposed by the second mounting part 126 on the branch pipe, result in the housing 120 constraining the main pipe and branch pipe in intersecting directions. This means the constraint effects of the housing 120 on the main pipe and branch pipe are mutually intersecting, thus the entire connector 110 is completely constrained by the housing 120. Specifically, the first mounting part 125 provides a radial constraint force on the main pipe 111, thus restricting the main pipe 111 from moving radially. The constraint force of the first mounting part 125 on the main pipe 111 can also provide a circumferential and axial constraint force on the branch pipe 112, thus restricting the branch pipe 112 from rotating or moving about its own axis. The second mounting part 126 provides a radial constraint on the branch pipe 112, thus restricting the branch pipe 112 from moving radially. The constraint force of the first mounting part 125 on the main pipe 111 can also be used by the second mounting part 126 to provide a circumferential and axial constraint force on the main pipe 111, thus restricting the main pipe 111 from rotating or moving about its own axis. The multiple constraint forces combined on the same connector 110 allow for complete positioning and installation of the connector 110 on the housing 120. The housing 120 does not require a separate fixing structure to achieve stable installation of the connector 110, which reduces the installation difficulty of the connector 110 and improves the assembly efficiency of the connector 110.

[0027] Please see Figure 2 The branch pipe 112 is equipped with a control valve 1122, which is used to adjust the opening of the branch channel, which can be used for negative pressure suction operation. As the opening of the branch channel increases or decreases, the negative pressure suction effect of the branch channel will increase or decrease accordingly, facilitating adjustment of negative pressure suction by medical personnel during use. The control valve 1122 has a control switch 1121, which is offset from the surface of the housing 120 forming the second mounting portion 126 along a first direction. At least a portion of the projection of the control switch 1121 along the first direction is located on the housing 120. The first direction can be the width direction of the housing 120 (e.g., the width direction of the housing 120). Figure 1 As shown in L1 in the diagram), that is, the width direction of the endoscope 2. In other words, the control switch 1121 and the housing 120 are in the height direction of the housing 120 (as shown in L1 in the diagram). Figure 1The overlapping portion is shown in L2. This overlapping arrangement effectively reduces the height difference between the housing 120 and the control switch 1121, so that when the operator adjusts the control switch 1121, there is no need to make a large lifting or pressing motion with the hand. The operator can touch and operate the switch more naturally and effortlessly, which improves the convenience of adjustment.

[0028] Please see Figure 3 The housing 120 may include a first sub-housing 121 and a second sub-housing 122. The first sub-housing 121 and the second sub-housing 122 may have the same structure, for example, the first sub-housing 121 and the second sub-housing 122 may be symmetrically arranged. The first mounting part 125 and the second mounting part 126 are both provided in the first sub-housing 121. The main pipe 111 is adapted to be embedded in the first mounting part 125 of the first sub-housing 121, and the branch pipe 112 is adapted to be embedded in the second mounting part 126 of the first sub-housing 121. The second sub-housing 122 of the housing 120 can press the main pipe 111 and the branch pipe 112 into the first sub-housing 121. For example, the first mounting portion 125 of the first sub-shell 121 has a first groove 1211, where the main pipe 111 is installed. The second mounting portion of the first sub-shell 121 has a second groove 1221, where the branch pipe 112 is installed. The wall panel of the second sub-shell 122 can press the main pipe 111 and the branch pipe 112 into the first sub-shell 121. Furthermore, the assembler first installs the main pipe 111 and the branch pipe 112, which serve as connectors 110, into their corresponding positions on the first sub-shell 121. At this time, the connector 110 is approximately restricted by the first sub-shell 121, making it relatively stable and less prone to detachment, thus improving the stability of the assembly process. The assembler then fastens the second sub-shell 122 onto the first sub-shell 121. Through the pressing action of the second sub-shell 122, the connector 110 can be effectively prevented from detaching from the first sub-shell 121 during subsequent operations or movement. At the same time, the limiting effect of the first sub-shell 121 on the connector 110 is also enhanced, ensuring the stability of the connector 110 after installation.

[0029] Of course, in some other cases, the first mounting part 125 and the second mounting part 126 are formed by the interlocking of the first sub-shell 121 and the second sub-shell 122. Taking the first mounting part 125 as an example, the first mounting part 125 has a mounting hole, the first sub-shell 121 forms a first groove 1211, the second sub-shell 122 forms a second groove 1221, the first sub-shell 121 and the second sub-shell 122 interlock, the first groove 1211 and the second groove 1221 are interconnected and form a mounting hole, and the main pipe 111 is installed in the first mounting part 125, which will not be elaborated here.

[0030] In the embodiments of this application, please refer to Figure 2 The connector 110 also includes a pressure testing conduit 113, which can be used to insert a pressure testing guidewire. The pressure testing conduit 113 has a pressure testing channel suitable for connecting to the insertion part of the endoscope 2. The pressure testing guidewire can extend through the pressure testing channel to the distal end of the insertion part and obtain the pressure value at the distal end of the insertion part. When the distal end of the insertion part extends into the human body cavity, the pressure testing guidewire can obtain the pressure of the human body cavity. Furthermore, the relatively independent pressure testing conduit 113 reduces the risk of interference with the pressure testing guidewire results due to messy tubing, ensuring the accuracy of pressure monitoring data. The pressure testing conduit 113 is connected to at least one of the main conduit 111 and the branch conduit 112. Preferably, a reinforcing rib is provided between the pressure testing conduit 113 and at least one of the main conduit 111 and the branch conduit 112 to further improve the connection stability of the connector 110. The main conduit 111 and the branch conduit 112 can be stably installed on the housing 120, and the pressure testing conduit 113 connected to them can be stably fixed in the housing 120. The pressure testing pipe 113 is embedded in the housing 120. The housing 120 also provides protection and fixation for the pressure testing pipe 113, ensuring that the pressure testing pipe 113 is stably installed on the housing 120. At the same time, it can also provide constraint forces in other directions for the main pipe 111 and the branch pipe 112, further improving the installation effect of the connector 110. It can also prevent the pressure testing pipe 113 from being completely exposed to the outside and subjected to wear, corrosion or accidental impact, thus extending the service life of the pressure testing pipe 113.

[0031] In one implementation, please refer to Figure 3 The pressure testing pipe 113 is embedded in the second sub-shell 122. The wall of the second sub-shell 122 fits tightly against the outer wall of the pressure testing pipe 113, forming a comprehensive enclosure and constraint. When vibration occurs during equipment operation, or when subjected to external force during operation, the wall of the second sub-shell 122 provides stable support for the pressure testing pipe 113, effectively preventing any swaying or displacement of the pressure testing pipe 113 within the shell 120. This stable state directly ensures the integrity of the internal pressure testing channel of the pressure testing pipe 113, keeping it unobstructed and preventing bending or blockage due to pipe displacement. This ensures that the pressure testing guide wire can travel unimpeded within the channel and smoothly reach the predetermined position to complete the pressure testing work. Furthermore, the pressure testing pipe 113 is embedded in the second sub-housing 122, which can also transfer the load of the connector 110 to the second sub-housing 122, avoiding excessive load on the first sub-housing 121. The outer walls of the second sub-housing 122 and the pressure testing pipe 113 abut against each other, making the force between the first sub-housing 121 and the second sub-housing 122 more balanced, avoiding the problem of excessive load on a single housing 120, thereby enhancing the reliability and durability of the entire housing 120 structure in fixing each pipe component.

[0032] Of course, in some other embodiments, the pressure measuring pipe 113 may also be embedded in the first sub-shell 121. Furthermore, the pressure measuring pipe 113 may be located on the first sub-shell 121 at a location different from the first mounting portion 125 and the second mounting portion 126, which will not be elaborated here.

[0033] Please refer again to the embodiments in this application. Figure 3 The main pipe 111 is embedded in the first groove 1211 of the first sub-housing 121, and the pressure measuring pipe 113 is embedded in the second groove 1221 of the second sub-housing 122. The connector 110 may also include a baffle 115, which is installed between the main pipe 111 and the pressure measuring pipe 113, and connects the first sub-housing 121 and the second sub-housing 122 to seal the opening 123 formed by the connection of the first groove 1211 and the second groove 1221. The baffle 115, installed between the main pipe 111 and the pressure measuring pipe 113, and connecting the first sub-housing 121 and the second sub-housing 122, effectively seals the opening 123 formed by the connection of the first groove 1211 and the second groove 1221. The sealing effect of the baffle 115 on the opening 123 effectively prevents external dust, liquids, etc., from entering the interior of the housing 120, improving the overall sealing of the endoscope 2 and ensuring the normal working environment of the internal components.

[0034] Please see Figure 3 as well as Figure 4 The extension direction of the pressure testing pipe 113 intersects with the extension direction of the main pipe 111. The pressure testing pipe 113 and the main pipe 111 abut against each other at opposite ends of the opening 123, and the baffle 115 confines the connector 110 at the opening 123. The limiting effect of the baffle 115 cooperates with the wall of the opening 123, constraining the connector 110 from multiple directions, effectively limiting the range of motion of the connector 110, preventing unnecessary movement within the housing 120, and further enhancing the stability of the connector 110 installation.

[0035] Please see Figure 5 as well as Figure 6 A positioning plate 114 is provided on the outer periphery of the main pipe 111, and the housing 120 has a mounting groove 124. The positioning plate 114 is embedded in the mounting groove 124 to restrict the connector 110. When the positioning plate 114 is embedded in the mounting groove 124, it can be fixed to the main pipe 111 from the outer periphery. This further improves the fixing effect of the connector 110 in the housing 120 and improves the impact resistance of the endoscope 2, so that it can maintain a stable position even when subjected to external impact or vibration.

[0036] To achieve the above and other related objectives, this application provides an operating handle 1. Please refer to [link / reference]. Figure 7 The operating handle 1 includes the aforementioned mounting structure 100. This gives the operating handle 1 the beneficial effects of any of the aforementioned solutions, which will not be elaborated further here.

[0037] To achieve the above and other related objectives, this application provides an endoscope 2. Please refer to [link to application]. Figure 7 The endoscope 2 includes the aforementioned operating handle 1. This gives the endoscope 2 the beneficial effects of any of the aforementioned solutions, which will not be elaborated further here. The endoscope 2 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 2.

[0038] 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.

[0039] 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.

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.
