Description

An installation structure, a handle, and an endoscope Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an installation structure, a handle, and an endoscope. Background Technology

[0002] An endoscope is a commonly used medical device that can directly enter the body's natural channels, providing doctors with ample diagnostic information for disease treatment. However, the existing mounting structure for securing the instrument tube and signal lines has certain layout problems, wasting some space within the handle.

[0003] Therefore, providing an installation structure, handle, and endoscope that can reduce the space occupied by the first guide channel of the fixed instrument tube and the second guide channel of the fixed signal line is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] This application discloses an installation structure, a handle, and an endoscope to solve the technical problem in the related art where the layout of the first guide channel through which the instrument tube passes and the second guide channel through which the signal line passes has certain problems, wasting some of the space inside the handle.

[0005] To solve the above problems, this application adopts the following technical solution:

[0006] Firstly, an installation structure is provided within the handle of an endoscope;

[0007] The mounting structure has a first guide channel for the instrument tube to pass through and a second guide channel for the signal line to pass through;

[0008] The first guide channel and the second guide channel are offset in the installation direction;

[0009] In the installation direction, the first guide channel is lower than the second guide channel, and the projection of the extension path of the first guide channel intersects with the projection of the extension path of the second guide channel, so that the instrument tube passes through the installation side opening of the second guide channel.

[0010] The technical solution adopted in this application can achieve the following beneficial effects:

[0011] In the mounting structure of this application, the instrument tube passes through the first guide channel, and the signal line passes through the second guide channel. The first and second guide channels have a height difference in the mounting direction. By utilizing the space in the handle in the mounting direction, the first and second guide channels are integrated, allowing the signal line to tend towards a straight line and avoiding significant bending to avoid the instrument tube. This reduces the mounting area occupied by the instrument tube and signal line in the handle, optimizing the internal structural layout. After the instrument tube and signal line are installed, the projection of the extension path of the first guide channel intersects with the projection of the extension path of the second guide channel. Furthermore, the instrument tube passes through the mounting side opening of the second guide channel, ensuring that the signal line is always contained within the second guide channel, preventing it from detaching.

[0025] 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.

[0026] 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".

[0027] During the installation of the instrument tube 340 and the signal line 350, the inventors discovered that the first guide channel 140 through which the instrument tube 340 passes and the second guide channel 150 through which the signal line 350 passes occupy a certain amount of the installation area of ​​the handle 200, making the already limited space inside the handle 200 even more cramped and affecting the installation of other components inside the handle 200.

[0028] The following description, in conjunction with Figures 1-9, details an installation structure 100, a handle 200, and an endoscope 300 provided in this application, through specific embodiments and application scenarios.

[0029] Some embodiments of this application disclose an installation structure 100, as shown in Figures 1-3, including a first guide channel 140, a second guide channel 150, a first mounting component 120, an intermediate housing 110, and a second mounting component 130.

[0030] As shown in Figure 5, the mounting structure 100 is disposed within the handle 200 of the endoscope 300. The mounting structure 100 is used to fix the instrument tube 340 and the signal line 350 within the handle 200, thereby enabling the installation of the instrument tube 340 and the signal line 350.

[0031] As shown in Figure 2, the mounting structure 100 has a first guide channel 140 through which the instrument tube 340 passes and a second guide channel 150 through which the signal line 350 passes. The first guide channel 140 serves to guide and limit the installation of the instrument tube 340, and the second guide channel 150 also serves to guide and limit the installation of the signal line 350. By providing the first guide channel 140 and the second guide channel 150, a mounting base is provided for the instrument tube 340 and the signal line 350 to be installed within the handle 200.

[0032] As shown in Figure 2, the first guide channel 140 and the second guide channel 150 are offset in the installation direction. The height difference between the first guide channel 140 and the second guide channel 150 in the installation direction allows the longitudinal space of the handle 200 to facilitate the installation of the instrument tube 340 and the signal line 350. This makes the signal line 350 more likely to be straight and avoids significant bending to avoid the instrument tube 340, thus reducing the installation area occupied by the instrument tube 340 and the signal line 350 on the handle 200.

[0033] The installation direction is shown as L1 in Figure 2, and the same applies below.

[0034] As shown in Figures 2 and 9, in the installation direction, the first guide channel 140 is lower than the second guide channel 150, and the projection of the extension path of the first guide channel 140 intersects with the projection of the extension path of the second guide channel 150, so that the instrument tube 340 passes through the installation side opening 151 of the second guide channel 150.

[0035] After the instrument tube 340 and signal line 350 are installed, the projection of the extension path of the first guide channel 140 intersects with the projection of the extension path of the second guide channel 150, and the instrument tube 340 passes through the installation side opening 151 of the second guide channel 150, so that the instrument tube 340 can always stop and limit the signal line 350 within the second guide channel 150, thus preventing the signal line 350 from falling out of the second guide channel 150.

[0036] During use, the operator moves the handle 200, changing its position and state. Due to the low rigidity of the signal line 350, it is prone to drooping under gravity during movement, potentially detaching from the second guide channel 150. The instrument tube 340, however, has sufficient rigidity and is stably mounted within the first guide channel 140. As the handle 200 moves, the instrument tube 340 is less likely to detach from the first guide channel 140. Therefore, the instrument tube 340 is used to restrain and limit the signal line 350 within the second guide channel 150, preventing it from detaching during handle movement.

[0037] As shown in Figure 2, along the outer side of the bending direction of the first guide channel 140, the mounting structure 100 has several support portions 122 to support the guiding curved extension of the instrument tube 340. Due to the shape design of the handle 200, the instrument tube 340 needs to be bent and installed inside the handle 200. When the instrument tube 340 is bent, the bent portion will protrude along one side. By providing several support portions 122, the instrument tube 340 is supported, preventing the bent portion of the instrument tube 340 from lacking effective support and collapsing.

[0038] As shown in Figure 2, the support portion 122 extends along the bending direction of the first guide channel 140. By extending the support portion 122 along the bending direction of the first guide channel 140, the contact area between the support portion 122 and the instrument tube 340 can be increased, allowing the support portion 122 to better support the instrument tube 340.

[0039] As shown in Figure 2, there are two support portions 122, with their opposing sides extending to opposite sides of the mounting side opening 151. By extending the two support portions 122 to opposite sides of the mounting side opening 151, the length of the support portions 122 is maximized while ensuring that the support portions 122 do not interfere with the signal line 350 passing through the second guide channel 150. This increases the contact area between the support portions 122 and the instrument tube 340, further enabling the support portions 122 to better support the instrument tube 340.

[0040] In a preferred embodiment, one support portion 122 is located near the instrument mouth 210 of the handle 200, while the other support portion 122 is located away from the instrument mouth 210 of the handle 200. When the instrument tube 340 is bent and installed within the handle 200, due to the shape design of the handle 200, the bending curvature of the bent portion of the instrument tube 340 is greatest near the instrument mouth 210 and smallest away from the instrument mouth 210, gradually becoming straight. Therefore, by placing one support portion 122 near the instrument mouth 210 of the handle 200, the bent portion of the instrument tube 340 with the greatest curvature can be effectively supported. Furthermore, by placing another support portion 122 away from the instrument mouth 210 of the handle 200, the bent portion of the instrument tube 340 with the smallest curvature can be guided, ensuring that the distal end of the instrument tube 340 is axially aligned with the insertion portion 310.

[0041] As shown in Figures 2 and 3, the mounting structure 100 includes a first mounting member 120 and a second mounting member 130 arranged at intervals. The first mounting member 120 has a first guide groove 121 through which the signal line 350 passes, and the second mounting member 130 has a second guide groove 131 through which the signal line 350 passes. The first guide groove 121 and the second guide groove 131 constitute a second guide channel 150.

[0042] The signal cable 350 passes through the first guide groove 121 and the second guide groove 131 to complete the installation of the signal cable 350 within the handle 200, and the first guide groove 121 and the second guide groove 131 serve to guide the signal cable 350. The first mounting member 120 and the second mounting member 130 are spaced apart, so that there is a certain space between the first mounting member 120 and the second mounting member 130, which can be used to assemble other components. By spaced the first mounting member 120 and the second mounting member 130, the space occupied by the second guide channel 150 in the handle 200 can be reduced, ensuring that the signal cable 350 can be stably installed, while also optimizing the structural layout within the handle 200.

[0043] In this embodiment, as shown in Figures 1-3, there are multiple second mounting members 130. In the endoscope 300, the image information acquired by the camera module is transmitted to the host computer via the signal line 350 and displayed on the host computer. Therefore, the signal line 350 has a relatively long length. Several second mounting members 130 are arranged within the handle 200 along its length, increasing the total contact area between the second guide groove 131 and the signal line 350, thus making the signal line 350 more stably mounted within the handle 200. The multiple second mounting members 130 are spaced apart, ensuring that there is space between any two adjacent second mounting members 130. This space can be used to assemble other components, thus fully utilizing the space within the handle 200.

[0044] In this preferred embodiment, the second mounting component 130 can be 2, 3, 4 or more, and can be flexibly set according to usage requirements. This embodiment does not limit this.

[0045] As shown in Figures 2 and 3, the first mounting member 120 and / or the second mounting member 130 have a third guide groove 132 through which the traction rope 360 ​​passes.

[0046] As shown in Figure 4, the traction rope 360 ​​is disposed within the handle 200, and its distal end enters from the insertion part 310 and connects to the active bending section to drive the active bending section to bend. Since the traction rope 360 ​​has relatively low stiffness and a long length, it also requires guidance, and the extension direction of the traction rope 360 ​​is approximately the same as the extension direction of the signal line 350. Therefore, a third guide groove 132 is provided in the first mounting member 120 and / or the second mounting member 130 for the traction rope 360 ​​to pass through, so that the third guide groove 132 guides the traction rope 360. Furthermore, by integrating the third guide groove 132 into the first mounting member 120 and / or the second mounting member 130, there is no need to provide a separate traction rope 360 ​​guiding component, further optimizing the structural layout within the handle 200.

[0047] In some embodiments, the first mounting member 120 has a third guide groove 132 through which the traction rope 360 ​​passes.

[0048] In some embodiments, the second mounting member 130 has a third guide groove 132 through which the traction rope 360 ​​passes.

[0049] In some embodiments, the first mounting member 120 and the second mounting member 130 each have a third guide groove 132 through which the traction rope 360 ​​passes.

[0050] As shown in Figure 2, the first guide channel 140 is disposed on the first mounting member 120. By disposing of the first guide channel 140 on the first mounting member 120, the first guide channel 140 no longer needs to occupy additional space within the handle 200, further optimizing the structural layout within the handle 200.

[0051] As shown in Figure 2, the projections of the axis at the distal end of the first guide channel 140 and the axis at the distal end of the second guide channel 150 in the installation direction overlap, so that the bottom of part of the instrument tube 340 can be inserted into the second guide channel 150.

[0052] The projections of the distal axis of the first guide channel 140 and the distal axis of the second guide channel 150 in the installation direction overlap. After the instrument tube 340 is installed in the first guide channel 140, because the instrument tube 340 is a circular tube, in the overlapping part of the first guide channel 140 and the second guide channel 150, the bottom of the instrument tube 340 will be recessed into the second guide channel 150 to reduce the height of the second guide channel 150 in the installation direction. This allows the instrument tube 340 to better stop and limit the signal line 350 within the second guide channel 150. At the same time, the bottom of the instrument tube 340 being recessed into the second guide channel 150 also allows the second guide channel 150 to provide a certain constraint on the instrument tube 340 in the width direction.

[0053] The second guide channel 150 contains an adhesive that holds the signal line 350 and at least a portion of the instrument tube 340 together.

[0054] During use, the operator moves the handle 200, changing its position and state. Due to the low rigidity of the signal cable 350, it is prone to detaching from the second guide channel 150 when the handle 200 is moved. Therefore, by incorporating adhesive within the second guide channel 150, the connection strength between the signal cable 350 and the second guide channel 150 is increased, preventing entanglement or collisions caused by the signal cable 350 detaching from the second guide channel 150, thus further ensuring smooth data transmission. Correspondingly, since the bottom of part of the instrument tube 340 is recessed into the second guide channel 150, the adhesive also helps to secure the instrument tube 340, increasing the connection strength between the mounting structure 100 and the instrument tube 340.

[0055] As shown in Figures 1-3, the first guide channel 140 and the second guide channel 150 are disposed on the intermediate housing 110, which is located inside the handle 200. For ergonomic purposes, the handle 200 is curved for easy gripping. However, the curved inner wall of the handle 200 makes it difficult to properly position the first guide channel 140 and the second guide channel 150. Therefore, by using the intermediate housing 110, firstly placing the first guide channel 140 and the second guide channel 150 on the intermediate housing 110, and then installing the intermediate housing 110 inside the handle 200, the installation difficulty of the first guide channel 140 and the second guide channel 150 is reduced.

[0056] Specifically, as shown in Figures 5, 7, and 8, the handle 200 consists of an upper housing 201 and a lower housing 202, with an intermediate housing 110 connected to either the upper housing 201 or the lower housing 202. To facilitate the installation of the intermediate housing 110, the inner wall of either the upper housing 201 or the lower housing 202 has several ribs 204, allowing the end face of the intermediate housing 110 to abut against these ribs 204, thus ensuring stable installation. The intermediate housing 110 can be fixed to the ribs 204 on the inner wall of the upper housing 201 or the lower housing 202 using methods such as threaded connection, welding, bonding, or snap-fit, to complete the installation of the intermediate housing 110. This embodiment does not limit this method.

[0057] Specifically, the first mounting component 120 and the second mounting component 130 are disposed on the intermediate housing 110 and can be integrally formed with the intermediate housing 110. Correspondingly, the first mounting component 120 and several second mounting components 130 can also be fixed to the intermediate housing 110 by welding, bonding, snap-fitting, or other methods, which is not limited in this embodiment.

[0058] Accordingly, as shown in Figures 4 and 5, the intermediate housing 110 is used not only to install the instrument tube 340 and signal line 350, but also to install other components such as the wheel 320 and cable 330.

[0059] As shown in Figure 2, the distal end of the intermediate housing 110 is provided with a fixing part 111 for connecting the connector assembly 311 of the insertion part 310. The insertion part 310 is an important component for insertion into the patient's body cavity. Its connection with the fixing part 111 at the distal end of the intermediate housing 110 secures the insertion part 310. The connector assembly 311 is also connected to the handle 200. That is, any two of the connector assembly 311 of the insertion part 310, the intermediate housing 110, and the handle 200 can be interconnected, further improving the stability of the intermediate housing 110 and the connector assembly 311 of the insertion part 310 within the handle 200.

[0060] Specifically, as shown in Figures 6 and 7, the distal ends of the upper housing 201 and the lower housing 202 each have several snap-fit ​​grooves 203. The connector assembly 311 of the insertion part 310 has a snap-fit ​​part 312. The snap-fit ​​part 312 is embedded in the snap-fit ​​groove 203 to complete the fixed connection between the connector assembly 311 of the insertion part 310 and the upper housing 201 and the lower housing 202.

[0061] In this preferred embodiment, the connector assembly 311 of the insertion part 310 and the fixing part 111 are connected by a snap-fit ​​method. However, the connector assembly 311 of the insertion part 310 and the fixing part 111 can also be fixed by adhesive bonding, welding, or other methods; this embodiment does not limit this method.

[0062] Some embodiments of this application also disclose a handle 200, as shown in FIG8, including a mounting structure 100.

[0063] Some embodiments of this application also disclose an endoscope 300, as shown in FIG8, including a handle 200.

[0064] The endoscope 300 in this application embodiment can be a bronchoscope, pyeloscope, esophagoscope, gastroscope, colonoscope, otoscope, rhinoscope, oral endoscope, laryngoscope, colposcope, laparoscope, arthroscope, etc. This application embodiment does not specifically limit the type of endoscope 300.

[0065] 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.

[0066] Furthermore, 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.
