Description

Technical Field

[0001] The present application relates to a guide sheath, in particular to a visualization ureteral guide sheath. Background Art

[0002] In current clinical practice, when using a flexible ureteroscope to treat ureteral obstruction or stones, a ureteral guide sheath is usually used to establish a surgical channel. The ureteral guide sheath is inserted through the urethral orifice, and a catheter is placed through the bladder and ureter to establish a surgical working channel to facilitate the operation. Currently, the ureteral guide sheath consists of a sheath tube that acts as a channel and a sheath core that acts as an expansion guide. When inserting the ureteral guide sheath, the sheath tube and the sheath core are inserted into the ureter together under the guidance of the guide wire. After being inserted into place, the sheath core is pulled out and separated from the sheath tube.

[0003] During the operation, the operation is difficult because the guide wire is the only means of guidance. In addition, the specific position of the instrument inside the ureter cannot be accurately determined. If an abnormal catheter placement is encountered, the result cannot be known immediately, which can easily cause local damage to the human body.

[0004] Therefore, there is an urgent need for a visualized ureteral guide sheath that can determine the condition of entering the human body during surgery to solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of the present application is to provide a visualized ureteral guide sheath in order to solve the above-mentioned problems existing in the prior art.

[0006] In order to achieve the above application purpose, the present application adopts the following technical solution: The visualized ureteral guide sheath includes:

[0007] A sheath core is installed on the sheath core seat;

[0008] The sheath tube is installed outside the sheath core and on the sheath tube seat, and the inner wall is provided with a channel for the data line to pass through;

[0009] The camera is arranged at the head end of the sheath tube and is electrically connected to the data line. An LED fill light data line is arranged beside the camera, at least part of which is located outside the sheath tube, and a data line plug is arranged at the end away from the camera.

[0010] Working principle and beneficial effects: 1. Compared with the prior art, the surgeon of this application can observe the situation inside the ureter in real time through the camera, which improves the accuracy and safety of the operation. Such a visualization system enables the operator to judge the position of the instrument more intuitively and reduce the risk of the operation.

[0011] 2. Compared with the prior art, the present application retains the data line plug and no longer directly connects to the display device. It can be freely matched with the display device that supports the data line plug, which is more flexible and has lower cost than the one-piece non-detachable structure.

[0012] Furthermore, the data line extends from the sheath head end to the sheath tail end and extends out from the side of the sheath tail end, which can provide more functions and connection options for the visualized ureteral guide sheath system, thereby improving the efficiency and operability of the operation.

[0013] Furthermore, the camera head and the inner wall of the sheath are fixed by medical glue. By using medical glue to fix the camera head, the stability, sealing and accuracy of the system can be improved, thereby better meeting the visualization requirements in ureteral treatment surgery.

[0014] Furthermore, the location where the medical glue is fixed is located on the inner wall of the sheath. The medical glue fixation on the inner wall of the sheath can provide effective waterproofing and sealing. This is essential to prevent liquid from penetrating and damaging the camera and its related components, and can also prevent the medical glue from contacting the patient and causing the patient to be allergic.

[0015] Furthermore, the sheath includes an inner layer and an outer layer, and a channel for the data line to pass through is provided between the inner layer and the outer layer. The channel for the data line to pass through between the inner and outer layers helps to improve the stability, reliability and operability of the system, thereby enhancing the performance of the visualized ureteral guide sheath system.

[0016] Furthermore, a protective layer is provided on the inner wall of the channel, and a certain gap is formed between the protective layer and the data line and the camera. A protective layer is provided on the inner wall of the channel, and a certain gap is formed between the protective layer and the data line and the camera, which helps to improve the durability, maintainability and anti-interference of the system, thereby enhancing the performance of the visualized ureteral guide sheath system.

[0017] Furthermore, the socket of the data cable plug is Type-C or Type-A. Selecting Type-C or Type-A data cable plug can improve the versatility, compatibility and data transmission speed of the system, while providing more flexibility and convenience for the design of the system.

[0018] Furthermore, the sheath is divided into bendable and non-bendable, and the bendable angle is greater than 90°.

[0019] Furthermore, the data cable is at least USB 2.0 standard. Fast data transmission speed helps ensure that the image quality transmitted from the camera to the external device is not affected by delays. This is very important for doctors to observe and make decisions in real time during surgery. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

Therefore, the above terms should not be understood as limiting the present application.

[0026] like Figure 1-3 As shown, the visualization ureteral guide sheath includes:

[0027] The sheath core 1 is installed on the sheath core seat 2;

[0028] In this embodiment, as a dilator, the sheath core 1 and the sheath core seat 2 are existing structures, the distal end of the sheath core 1 extends out of the sheath tube 3, and a silicone cap 8 is also installed on the sheath core seat 2. The function is consistent with the existing technology, so its structure and principle are not repeated.

[0029] The sheath tube 3 is installed outside the sheath core 1 and on the sheath tube seat 4, and the inner wall is provided with a channel for the data line 5 to pass through. The sheath tube 3 is divided into bendable and non-bendable, and the bendable angle is greater than 90°;

[0030] In this embodiment, the function of the sheath 3 is based on the prior art, and an inner layer 31 and an outer layer 32 are added, and a channel for the data line 5 to pass through is provided between the inner layer 31 and the outer layer 32. The channel between the inner layer 31 and the outer layer 32 provides a relatively isolated space, which helps to protect the data line 5 from interference and damage from the external environment. This is very important for ensuring the reliability and durability of the data line 5, especially in the case of liquid, friction or other external pressures that may exist in the surgical environment. The channel between the inner and outer layers 32 may enhance the overall structural strength of the sheath 3. This is very important for ensuring the stability and durability of the sheath 3 during surgical operations, especially during the insertion and movement of the catheter.

[0031] Preferably, a protective layer 33 is provided on the inner wall of the channel, and there is a certain gap between the protective layer 33 and the data cable 5 and the camera 6. The protective layer 33 may be a polymer material such as silica gel. By providing a protective layer 33 on the inner wall of the channel and leaving a certain gap between the protective layer 33 and the data cable 5 and the camera 6, mechanical stress can be reduced. This design helps to reduce the impact on the data cable 5 and the camera 6 when inserting, moving or removing the catheter, and improves the durability of the system. By providing a protective layer 33 in the channel, a certain degree of isolation can be provided to prevent electromagnetic signals from interfering with the normal functions of the data cable 5 and the camera 6. This is very important for ensuring the stability and accuracy of the system.

[0032] A camera 6 is provided at the head end of the sheath tube 3 and is electrically connected to the data line 5, and an LED fill light is provided next to the camera 6;

[0033] In this embodiment, the camera 6 is an existing miniature camera 6, preferably a camera with a higher pixel, such as a 12-megapixel lens, and a product with a built-in LED fill light, which can provide a clearer picture.

[0034] Preferably, the camera 6 is fixed to the inner wall of the sheath 3 by medical glue, and the position where the medical glue is fixed is located on the inner wall of the sheath 3. Fixing the camera 6 to the inner wall of the sheath 3 can provide additional stability to ensure that the position of the camera 6 does not change during the operation. This is critical for obtaining clear and stable images and helps to improve the accuracy of the operation. By fixing the camera 6 with medical glue, a more accurate positioning of the position of the camera 6 can be achieved. This is very important to ensure that the camera 6 can accurately capture the details inside the ureter, helping doctors to better navigate and perform the operation. Fixing the camera 6 on the inner wall of the sheath 3 helps prevent external stray substances from entering the camera 6 area, thereby maintaining the clarity of the image and the sanitary environment. The medical glue fixation on the inner wall of the sheath 3 can provide effective waterproofing and sealing. This is crucial to prevent liquids from penetrating and damaging the camera 6 and its related components, especially body fluids and washing fluids that may be present in the clinical environment. Fixing the position of the camera 6 helps to simplify the surgical operation. The doctor does not need to worry about the change in the position of the camera 6, and can focus more on the surgical process, improving the efficiency of the overall operation.

[0035] The data cable 5 is at least partially located outside the sheath 3 , and a data cable 5 plug 7 is provided at one end away from the camera 6 .

[0036] In this embodiment, the data line 5 extends from the head end of the sheath tube 3 to the tail end of the sheath tube 3, and extends from the side of the tail end of the sheath tube 3. Preferably, the socket of the plug 7 of the data line 5 is Type-C or Type-A. Type-C or Type-A, the system will be more versatile and compatible. These two plug 7 standards are widely used in the market, and many devices support these two types of interfaces, thereby reducing the problem of connecting with other devices.

[0037] Preferably, the Type-C plug 7 can generally support higher data transmission speeds, such as 5Gbps of USB3.0 or higher transmission standards, so that images and other relevant data captured by the camera 6 can be transmitted faster. This helps to monitor in real time and ensure instant feedback during surgery. The Type-C plug 7 supports the power transmission function, which means that the system can provide power to the device connected to it through this plug 7, thereby reducing the need for additional power cords. Type-A plug 7 is widely used in many electronic devices, while Type-C plug 7 is becoming more and more common in modern devices. Choosing one of them can ensure that the system can be connected to a variety of devices, improving the versatility of the device. The Type-C plug 7 is generally relatively small, which helps to design a more compact system, especially when designing medical devices in limited space.

[0038] The parts not described in detail in this application are prior art, so this application does not describe them in detail.

[0039] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0040] Although the terms such as sheath core 1, sheath core seat 2, sheath tube 3, sheath tube seat 4, data cable 5, camera 6, plug 7, silicone cap 8, inner layer 31, outer layer 32, protective layer 33 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of this application; interpreting them as any additional restrictions is contrary to the spirit of this application.
