Description

Technical Field

[0001] This utility model relates to the field of endoscope technology, and more specifically, to a component for expanding the instrument channel of an endoscope. Background Technology

[0002] With the rapid development of modern medical technology, endoscopic examinations and treatments have become an indispensable part of clinical diagnosis and treatment. However, in practical applications, traditional single-channel endoscopes are unable to meet the growing medical needs due to their limitations. Single-channel endoscopes are designed to allow only one diagnostic or therapeutic accessory to pass through at a time, meaning that doctors need to frequently change accessories during examinations or treatments. This is not only cumbersome but also increases the risk of operational errors that may occur during accessory changes. Furthermore, such frequent changes can prolong surgical time, increase patient discomfort, and raise surgical risks.

[0003] To overcome the limitations of single-channel endoscopes, dual-channel endoscopes were developed. The design of dual-channel endoscopes allows for the simultaneous insertion of two diagnostic and therapeutic attachments, thereby improving the flexibility and efficiency of surgery. However, because dual-channel endoscopes need to accommodate two channels, their diameter is correspondingly larger, which can affect patient comfort to some extent. This is especially true during long or complex surgeries, where patients may experience greater discomfort, potentially even hindering the successful completion of the procedure.

[0004] Therefore, how to improve patient comfort while ensuring surgical efficiency has become an urgent problem to be solved in the field of endoscopy. Summary of the Invention

[0005] To address or alleviate the problems of limited functionality of existing single-channel endoscopes affecting surgical efficiency and the negative impact of dual-channel endoscopes on patient experience, this invention provides a component for expanding the instrument channel of an endoscope.

[0006] The technical solution of this utility model is as follows:

[0007] An assembly for expanding an endoscope's instrument channel includes a tip cap and a fixation cap. The tip cap is used to connect to the tip of an endoscope. A connecting seat is provided on one side of the tip cap, and a flexible catheter is connected to the connecting seat. The fixation cap includes a first connecting portion detachably connected to the endoscope and a second connecting portion detachably connected to the flexible catheter. The first connecting portion is movably connected to the endoscope, and the second connecting portion is movably connected to the flexible catheter.

[0010] Furthermore, both the first connecting part and the second connecting part are sleeve-shaped, and the first connecting part and the second connecting part are arranged side by side. The inner diameter of the first connecting part is equivalent to the outer diameter of the endoscope, and the inner diameter of the second connecting part is equivalent to the outer diameter of the flexible catheter.

[0011] Furthermore, a suction cup is provided on the inner wall of the first connecting part, which increases the adsorption strength between the inner wall of the first connecting part and the surface of the endoscope.

[0012] Furthermore, the first connecting part has a first incision on its side wall, and the second connecting part has a second incision on its side wall. The first incision and the second incision are far apart from each other. The first incision opens elastically to place an endoscope, and the second incision opens elastically to place a flexible catheter.

[0013] Furthermore, multiple second connecting portions are provided, and the multiple second connecting portions surround the first connecting portion circumferentially.

[0014] Furthermore, the tip cap and the flexible catheter are an integral structure.

[0015] Furthermore, the material of the tip cap is thermoplastic elastomer, thermoplastic polyurethane elastomer, silicone rubber, silicone, or polyvinyl chloride.

[0016] Furthermore, the flexible catheter is made of polyetheretherketone, block polyetheramide resin, polyamide fiber, polytetrafluoroethylene, perfluoroethylene propylene, or fluorinated ethylene propylene copolymer.

[0017] Furthermore, the tip cap includes a connecting hole, the inner diameter of which is equivalent to the outer diameter of the tip of the endoscope, and the tip cap and the tip of the endoscope are engaged and connected.

[0018] The advantages of this utility model according to the above-described solution are as follows: Firstly, by providing a detachable fixing cap, the endoscopic instrument channel can be easily expanded, allowing doctors to operate multiple diagnostic and therapeutic accessories simultaneously, thus improving the flexibility and efficiency of surgery.

[0028] like Figure 1 and Figure 2 As shown in one embodiment of the present invention, an assembly for expanding the instrument channel of an endoscope includes a tip cap 1 and a fixing cap 3. The tip cap 1 is used to connect the tip of the endoscope 2. A connecting seat 103 is provided on one side of the tip cap 1, and a flexible catheter is connected to the connecting seat 103. The fixing cap 3 includes a first connecting part 301 that is detachably connected to the endoscope 2 and a second connecting part 302 that is detachably connected to the flexible catheter 102. The first connecting part 301 is movably connected to the endoscope 2, and the second connecting part 302 is movably connected to the flexible catheter 102.

[0029] In use, the doctor connects the tip cap 1 to the tip of the endoscope 2, ensuring a stable connection. The connecting seat 103 is then connected to the flexible catheter 102. Subsequently, the doctor connects the first connecting part 301 of the fixing cap 3 to the endoscope 2, and the second connecting part 302 of the fixing cap 3 to the flexible catheter 102 of the tip cap 1. Utilizing the movable connection design, the fixing cap 3 can be adjusted in position during use while maintaining the connection between the endoscope 2 and the flexible catheter 102, thus creating a stable yet flexible channel structure.

[0030] During the procedure, doctors can insert medical accessories, such as forceps, scissors, or suction devices, into the channel structure, thereby improving the flexibility and efficiency of the surgery.

[0031] In this embodiment, by setting the tip cap 1 and the fixing cap 3, the instrument channel of the endoscope 2 is expanded, allowing the surgeon to operate multiple diagnostic and therapeutic accessories simultaneously, thus improving the flexibility and efficiency of the surgery. Secondly, due to the use of a movable connection, the fixing cap 3 can be adjusted to suit the needs of the surgery, eliminating the need for frequent disassembly and repositioning, making it convenient for the surgeon to use. Furthermore, the component has a compact structure and a relatively small overall diameter, which reduces irritation to the patient and improves the patient's experience.

[0032] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the endoscope 2 includes a curved section 201 and an insertion section 202, and multiple fixing caps 3 are provided, with at least one fixing cap 3 provided for the curved section 201 and the insertion section 202.

[0033] A fixing cap 3 is provided at the end of the curved section 201 and the end of the insertion section 202, respectively.

[0034] In this embodiment, by providing fixing caps 3 at the ends of the curved section 201 and the insertion section 202 respectively, the structural stability and safety of the endoscope 2 are improved. Providing fixing caps 3 at both the curved section 201 and the insertion section 202 of the endoscope 2 ensures a stable connection between the flexible catheter 102 and the endoscope 2, preventing separation due to external forces during surgery or examination, ensuring precise control of the endoscope 2, and maintaining stable image transmission.

[0035] like Figure 5 As shown, in a preferred embodiment, both the first connecting part 301 and the second connecting part 302 are sleeve-shaped, and the first connecting part 301 and the second connecting part 302 are arranged side by side. The inner diameter of the first connecting part 301 is equivalent to the outer diameter of the endoscope 2, and the inner diameter of the second connecting part 302 is equivalent to the outer diameter of the flexible catheter 102.

[0036] The first connecting part 301 has a first incision 303 on its side wall, and the second connecting part 302 has a second incision 304 on its side wall. The first incision 303 and the second incision 304 are far apart from each other. The first incision 303 is elastically opened to place the endoscope 2, and the second incision 304 is elastically opened to place the flexible catheter 102.

[0037] Multiple second connecting portions 302 are provided, and the multiple second connecting portions 302 surround the first connecting portion 301 in a circumferential direction.

[0038] The inner wall of the first connecting part 301 is provided with suction cups 305, which are evenly distributed on the inner wall of the first connecting part 301.

[0039] In this embodiment, a stable connection between the endoscope 2 and the flexible catheter 102 is achieved by using a sleeve-shaped first connecting part 301 and a second connecting part 302. The first connecting part 301 and the second connecting part 302 can slide on the endoscope 2 and the flexible catheter 102 respectively, allowing for position adjustment. The inner diameter of the first connecting part 301 matches the outer diameter of the endoscope 2, thus ensuring a secure connection and preventing detachment during use, thereby guaranteeing the clarity of image transmission and the accuracy of operation. Similarly, the inner diameter of the second connecting part 302 matches the outer diameter of the flexible catheter 102, thus ensuring a secure connection. Furthermore, by providing a first incision 303 and a second incision 304, the two connecting parts can be elastically opened, facilitating quick installation of the endoscope 2 and the flexible catheter 102 and improving operational efficiency. Furthermore, the circumferential arrangement of multiple second connecting portions 302 surrounding the first connecting portion 301 not only makes the structure more compact and reduces the overall size, but also enhances the stability of the overall structure. It also provides more connection options for the flexible catheter 102, further improving the flexibility of medical device use and expanding its applicability. Finally, by providing a suction cup 305 on the inner wall of the first connecting portion 301, after the first connecting portion 301 is connected to the endoscope 2, the suction cup 305 can adhere to the surface of the endoscope 2, thereby improving the connection strength between the first connecting portion 301 and the endoscope 2 and ensuring connection stability.

[0040] like Figure 3 As shown, in a preferred embodiment, the tip cap 1 and the flexible conduit 102 are an integral structure.

[0041] The tip cap 1 and the flexible catheter 102 are tightly bonded together using methods such as heat fusion or adhesive bonding to form a single integrated structure. This integrated structure enhances structural stability, prevents the tip cap 1 from separating from the flexible catheter 102 during use, and improves overall reliability. Simultaneously, the integrated structure simplifies the assembly process, reduces the number of parts, and facilitates operation and use by medical personnel. Furthermore, the integrated structure helps improve the seal between the tip cap 1 and the flexible catheter 102, effectively preventing the penetration of liquids or gases and ensuring safety during surgery or examinations.

[0042] In a preferred embodiment, the tip cap 1 is made of thermoplastic elastomer, thermoplastic polyurethane elastomer, silicone rubber, silicone, polyvinyl chloride, etc.

[0043] The flexible catheter 102 is made of materials such as polyetheretherketone, block polyetheramide resin, polyamide fiber, polytetrafluoroethylene, perfluoroethylene propylene, and fluorinated ethylene propylene copolymer.

[0044] In practical applications, appropriate materials can be selected based on usage requirements, production conditions, costs, etc., including but not limited to the types of materials listed above.

[0045] like Figure 3 and Figure 4 As shown, in a preferred embodiment, the tip cap 1 includes a connection hole 104, the inner diameter of which is equivalent to the outer diameter of the tip of the endoscope 2, and the tip cap 1 and the tip of the endoscope 2 are engaged and connected.

[0046] The tip cap 1 is equipped with a warning line 101 and a water outlet 105. The water outlet 105 can prevent water from affecting the field of vision during the operation, and the warning line 101 can be used as a reference for the installation position to limit the installation position of the endoscope 2.

[0047] In this embodiment, on the one hand, a secure connection is ensured between the tip cap 1 and the tip of the endoscope 2, improving the stability and reliability of the entire device; on the other hand, the snap-fit ​​connection simplifies the installation steps and improves operational efficiency, allowing medical personnel to more easily connect the tip of the endoscope 2 to the tip cap 1, saving valuable time during surgery or examination. Furthermore, this connection method also has good compatibility and versatility, applicable to various sizes and models of endoscopes 2, facilitating clinical use.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
