Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a multi-lumen tube, a multi-functional tube, and a medical multi-functional microelectronic endoscope device. Background Technology

[0002] The physiological structure and diseases of small cavities such as the vas deferens, fallopian tubes, and eustachian tubes, which play an important role in the normal physiological functions of the human body, have always been topics of medical research. With the advancement of science and technology, interventional diagnosis and treatment surgery has gradually become one of the development trends.

[0003] The functional cannulas of medical electronic endoscopes typically employ a single or composite material single-channel or intracavitary multi-cavity design. Multi-cavity medical electronic endoscopes with this design usually contain multiple channels for different functions, such as suction, degassing, flushing, balloon dilation, and transmission of image signals and light sources. These channels are carefully arranged within the multi-cavity cannulas to ensure free movement of components without interference. However, existing multi-cavity cannulas, designed to accommodate different channel functions, have fixed internal dimensions for image signal and light source transmission. Therefore, when additional cavities are needed to achieve other functions, the size of the multi-cavity cannulas usually needs to be increased. Currently, the insertion tube size of commercially available medical electronic endoscopes is generally above 1.00 mm, resulting in excessively large multi-cavity cannulas. This not only makes it difficult to enter some narrow, small cavities in the human body but also limits the scope of application of the endoscope. For example, when examining areas with small lumens, such as the genitals and middle ear, the excessively large outer diameter of the multi-cavity cannulas can cause insertion difficulties or prevent reaching the target area, increasing patient discomfort. Furthermore, the models, specifications, and dimensions of currently available microelectronic CMOS sensors (such as OmniVision OCHTA10-RALA) cannot be increased to enlarge other cavity sizes by reducing the maximum effective diameter of the multifunctional tube lumen, thus hindering further medical research on the aforementioned microcavities. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-lumen tube for a medical multifunctional micro-electronic endoscope device, which can realize three or more treatment methods such as visual observation and diagnosis, irrigation, balloon dilation and aspiration of micro-cavities such as the vas deferens, fallopian tubes and eustachian tubes.

[0034] To facilitate understanding of this utility model, the specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.

[0035] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0036] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the related listed items.

[0037] It should be noted that in this article, "fixed to" or "connected to" can mean directly fixed to or connected to a component, or indirectly fixed to or connected to a component.

[0038] This utility model embodiment provides a multi-lumen tube 1, which can be used with commercially available miniature electronic CMOS sensors (OmniVision OCHTA10-RALA). Combined with flushing, balloon dilation, and aspiration devices, it enables real-time visualization and diagnosis of small cavities such as the vas deferens, fallopian tubes, and Eustachian tubes, as well as three or more treatment methods including flushing, balloon dilation, and aspiration. Figures 3 to 5As shown, the multi-lumen tube 1 includes a first tube body and a second tube body 13. The first tube body is sleeved outside the second tube body 13, that is, the second tube body 13 is disposed in the inner layer of the multi-lumen tube 1, and the first tube body is disposed in the outer layer of the multi-lumen tube 1, with the first tube body and the second tube body 13 in close contact. A groove 131 is formed on the outer wall of the second tube body 13, and the groove 131 extends recessedly along the axial direction of the second tube body 13 to form a cavity 14. It should be noted that the hollow inner cavity 132 inside the second tube body 13 is a channel for transmitting image signals and light sources. The inner cavity 132 is located at the exact center of the second tube body 13, which can ensure imaging quality, enable visual observation and diagnosis, and make it easier for the operator to control the position and angle of the endoscope during operation, so as to achieve more precise examination and treatment. The second tube 13 has grooves 131 formed on its outer wall. The number of grooves 131 can be set according to actual needs, such as one, two, three or other numbers. Specifically, it can be set according to medical needs, such as the need to realize treatment methods such as flushing, irrigation, aspiration, drainage, and dilation. The corresponding number of grooves 131 is set according to the required function, so that the grooves 131 extend along the axial direction of the second tube 13 to form a cavity 14. Different instruments can be inserted into the cavity 14 to realize treatment methods such as flushing, irrigation, aspiration, drainage, and dilation.

[0039] Therefore, the multi-lumen tube 1, through the design of its internal optimized structure, specifically by creating a groove 131 on the outer peripheral wall of the second tube 13 to form a cavity 14, ensures that the channel for transmitting image signals and light sources is in the exact center of the multi-lumen tube 1, avoiding positional deviation that could affect imaging quality and accuracy. On the other hand, the layout structure of the internal cavity 14 of the multi-lumen tube 1 can effectively improve the space utilization rate inside the multi-lumen tube 1. Under the premise of ensuring the required size of the internal cavity 132 channel for transmitting image signals and light sources, multiple cavities 14 are added to insert different instruments, so as to realize multi-mode treatment methods such as irrigation, perfusion, aspiration, drainage, and dilation. This allows the maximum effective diameter of the internal cavity 132 channel for transmitting image signals and light sources to be no less than 25%, forming a multi-lumen tube 1 with multiple lumen channels without increasing the size.

[0040] In some embodiments, such as Figure 4 and Figure 5As shown, the groove 131 of the second tube 13 forms an opening on the side near the first tube, and the cavity 14 is formed between the wall of the groove 131 of the second tube 13 and the inner wall of the first tube. The open, non-closed groove 131 formed on the outer wall of the second tube 13 maximizes the space utilization inside the multi-cavity tube 1. Because the groove 131 is non-closed, its shape can be adapted to the thickness and shape of the second tube 13 wall, forming a composite irregular multi-cavity tube 1 structure with multiple cavities 14.

[0041] In some embodiments, such as Figure 4 As shown, the outer wall of the second tube 13 is recessed inward along its radial direction to form the groove 131, and the outer wall of the second tube 13 is provided with a plurality of grooves 131 along its circumferential direction, each groove 131 being independently arranged. By creating multiple grooves 131 on the outer wall of the second tube 13, treatment methods such as flushing, irrigation, suction, drainage, and dilation can be simultaneously achieved. Specifically, in this embodiment, the outer wall of the second tube 13 is provided with four grooves 131 along its circumferential direction, and the four grooves 131 are evenly distributed in the circumferential direction of the second tube 13.

[0042] In some embodiments, such as Figure 4 As shown, the first tube body includes a covering layer 11 and a braided layer 12; the covering layer 11, the braided layer 12, and the second tube body 13 are arranged sequentially, and the braided layer 12 tightly covers the second tube body 13. The braided layer 12 is woven using a 1:2 braiding method. This braided layer 12 is disposed inside the multi-cavity tube 1, which improves its torsional resistance. The braided layer 12 is in close contact with the second tube body 13, forming a cavity 14 between the wall of the groove 131 and the inner wall of the braided layer 12. The braided layer 12 then seals the opening of the groove 131, forming a closed cavity 14.

[0043] In some embodiments, the single-sided wall thickness of the covering layer 11 is not less than 0.08 mm, wherein the single-sided wall thickness refers to the thickness of one side of the tube body of the covering layer 11, and its thickness is sufficient to wrap the braided layer 12 to form protection, without any special limitation.

[0044] In some embodiments, the single-sided wall thickness of the braided layer 12 is not less than 0.05 mm.

[0045] In some embodiments, the braided layer 12 is a metal braided layer. Specifically, the metal braided layer can be a 304 stainless steel wire, nickel-titanium alloy wire, or titanium wire braided layer. In this embodiment, it is a stainless steel braided layer, which is made of stainless steel wire woven into a tight structural layer. It has high tensile strength and wear resistance, which allows the stainless steel braided layer to withstand greater tensile and impact forces and is not easily damaged.

[0046] In some embodiments, the covering layer 11 is a tube structure made of PA (polyamide), PEBAX (polyether block amide) or TPE (thermoplastic elastomer) material, which has excellent tensile strength, toughness and wear resistance.

[0047] In some embodiments, the inner diameter of the second tube 13 is not less than 1.2 mm.

[0048] In some embodiments, the second tube 13 is a polymer material tube, and the surface of the second tube 13 is a smooth surface. The second tube 13 can be a tube structure made of PTFE (polytetrafluoroethylene), PI (polyimide), or PA (polyamide) material, which has a smooth surface, reduces friction, facilitates instrument insertion into the cavity 14, and has sufficient structural strength to achieve a thin-layer structure.

[0049] In some embodiments, such as Figure 4 As shown, the groove 131 is an irregularly shaped groove structure. An irregularly shaped groove structure refers to a groove structure whose cross-sectional shape and size can be customized according to actual needs, offering greater flexibility. Specifically, the radial dimension of at least one of the grooves 131 is the same as or not less than 1.5 times the radial dimension of the other grooves 131. By setting the groove 131 as an irregularly shaped groove structure, the space utilization rate inside the multi-cavity tube 1 can be maximized. The shape of the groove 131 can be adapted to the thickness and shape of the second tube 13 wall, forming a composite irregularly shaped multi-cavity tube 1 structure with multiple cavities 14.

[0050] In some embodiments, the hollow internal structure of the second tube 13 is an inner cavity 132, the diameter of which is larger than the diameter of the groove 131, so that the dimensions of the inner cavity 132 and the groove 131 of the second tube 13 can meet the diversity and volume of different instruments and tools.

[0051] The following is a comparative analysis of the structures of two existing multi-lumen tubes 1 and the multi-lumen tube 1 of the present invention.

[0052] like Figure 1 As shown, this is a conventional structure of an existing multi-lumen tube 1: it includes a covering layer 11, a braided layer 12, and a second tube body 13 arranged sequentially from the outside to the inside. The hollow structure inside the second tube body 13 forms an inner cavity 132 structure. Four closed cavities 14 are formed at the tube wall of the second tube body 13. The diameter of the inner cavity 132 of the second tube body 13 is required to meet the insertion of the insertion tube 70 of the micro-electronic endoscope. Since the second tube body 13 needs to have sufficient thickness to hollow out the cavity 14, the thickness of the second tube body 13 is increased, which increases the overall thickness of the multi-lumen tube 1.

[0053] like Figure 2 As shown, another conventional structure of the existing multi-cavity tube 1 includes a covering layer 11, a braided layer 12, and a second tube body 13 arranged sequentially from the outside to the inside. The second tube body 13 has an inner cavity 132 and a channel 14, which is formed by hollowing out one side of the thicker tube wall of the second tube body 13. In this type of multi-cavity tube 1, the tube wall of the second tube body 13 is thicker on one side and thinner on the other side. Although this ensures that the overall increase in the thickness of the multi-cavity tube 1 is not significant, it causes the inner cavity 132 of the second tube body 13 to be significantly off-center, which affects the imaging quality and accuracy.

[0054] like Figure 3 As shown, the multi-lumen tube 1 structure of this utility model embodiment includes a covering layer 11, a braided layer 12, and a second tube body 13 arranged sequentially from the outside to the inside. The outer wall of the second tube body 13 has four grooves 131 along its circumferential direction. An opening is formed on the side of the grooves 131 near the braided layer 12, and a cavity 14 is formed between the wall of the grooves 131 and the inner wall of the braided layer 12. The multi-lumen tube 1 of this embodiment can form multiple cavities 14 within the relatively thin wall of the second tube body 13, effectively improving the internal space utilization. While ensuring the required size of the inner cavity 132 channel for transmitting image signals and light sources, multiple cavities 14 are added to insert different instruments, enabling multi-mode treatment methods such as irrigation, perfusion, aspiration, drainage, and dilation. This ensures that the maximum effective diameter of the inner cavity 132 into which the CMOS camera is inserted is not less than 25%, forming a multi-lumen tube 1 with multiple cavities without increasing the overall size, and ensuring that the channel for transmitting image signals and light sources is in the exact center of the multi-lumen tube 1.

[0055] This utility model also provides a multifunctional tube 10, such as Figure 6 and Figure 7 As shown, the multifunctional tube 10 includes a connector 2, a tip tube 3, and a multi-lumen tube 1 as described above. One end of the multi-lumen tube 1 is connected to the connector 2, and the other end is connected to the tip tube 3. The connector 2 consists of a channel connector, an expansion / suction connector, and a flushing connector, used to perform treatments such as flushing, irrigation, suction, drainage, and expansion. The tip tube 3 is made of a soft polymer material such as PEBAX, silicone rubber, or polyurethane. Specifically, the proximal end of the multi-lumen tube 1 is sleeved with the channel connector in the connector 2, and the channel connector communicates with the inner lumen 132 of the second tube body 13. The expansion / suction connector and the flushing connector communicate with the lumen 14 of the multi-lumen tube 1. The soft polymer material tip tube 3 covers the end of the multi-lumen tube 1.

[0056] This utility model also provides a medical multifunctional microelectronic endoscope device 100, such as Figure 8 and Figure 9 As shown, the medical multifunctional microelectronic endoscope device 100 includes a microelectronic endoscope and a multifunctional tube 10 as described above; the microelectronic endoscope includes an operating handle 20 and an insertion tube 70 connected to the operating handle 20, and the insertion tube 70 of the microelectronic endoscope is inserted into the second tube body 13 through the connector 2. The operating handle 20 may be equipped with an adapter 50, adjustment buttons 40 such as a recording button, zoom in / out button, brightness adjustment button, etc., and an adjustable bending cylinder 60, etc.

[0057] In some embodiments, such as Figure 8 and Figure 9 As shown, the insertion tube 70 is detachably connected to the connector 2. Specifically, the insertion tube 70 is provided with a connector 30, and the insertion tube 70 is detachably connected to the connector 2 of the multifunctional tube 10 through the connector 30. The connector 30 can be a conventional Luer connector or other structure capable of detachably connecting and communicating two components; no particular limitation is made here. Understandably, the detachable connection between the two allows the multifunctional tube 10 to be a disposable tube, which can be reused after use by replacing the multifunctional tube 10, thus reducing costs. Of course, in other embodiments, the microelectronic endoscope can also be fixedly connected to the multifunctional tube 10, forming a disposable medical multifunctional microelectronic endoscope device 100.

[0058] The above embodiments are not an exhaustive list based on the present invention, and there may be other embodiments not listed. Any substitutions and improvements made without departing from the concept of the present invention are within the protection scope of the present invention.
