Description

Technical Field

[0001] This utility model relates to the field of surgical instrument technology, and more specifically, to a visualized iridocorneal separator. Background Technology

[0002] Anterior chamber angle separation is a common surgical procedure for angle-closure glaucoma. During the procedure, the mechanical blunt separation action of the anterior chamber angle separator separates the adhered anterior chamber angle, thereby exposing the functional trabecular meshwork area, achieving the purpose of aqueous humor drainage and reducing intraocular pressure.

[0003] Currently, because the structure in front of the anterior chamber angle is the limbus, direct light sources cannot reach the anterior chamber angle directly. Therefore, in traditional surgery, doctors often use surgical instruments to blindly separate the anterior chamber angle, but this can easily lead to damage to the iris and the anterior chamber angle. Alternatively, gonioscopes are used as an auxiliary tool to observe the anterior chamber angle structure and guide the separation operation. However, the use of gonioscopes is highly dependent on transparent corneal tissue, because only a transparent cornea can ensure that doctors can clearly see the anterior chamber angle structure.

[0004] While gonioscopy plays a crucial role in goniosynostosis, its application has certain limitations, particularly when dealing with patients in poor corneal condition. Clinically, the corneas of some patients may be affected by various factors, such as corneal edema, corneal scarring, corneal degeneration, corneal bullae, or large pterygium, leading to decreased corneal transparency or irregularity. When the cornea is in poor condition, gonioscopy cannot provide a clear field of vision, making it difficult for the surgeon to accurately determine the location and structure of the angle, thus affecting the precision and safety of the separation procedure. Furthermore, even if the surgeon is able to perform the surgery, the unclear field of vision may lead to poor surgical results or even complications, increasing the difficulty and risk of the operation. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a visual corner separator in view of the above-mentioned defects of the prior art.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A visual corner separator is constructed, comprising: a handle, an endoscope assembly, and a separation component. The endoscope assembly includes an insertion part, which is connected to the lower end of the handle and forms an angle. The separation component is disposed on the front end face of the insertion part and is arranged along the axial direction of the insertion part. The endoscope assembly can obtain a view around the separation component through the insertion part.

[0008] As an improvement to the aforementioned corner separator, the included angle between the insertion part and the handle is 140-150 degrees.

[0009] As an improvement to the aforementioned corner separator, the included angle is 145 degrees.

[0010] As an improvement to the aforementioned corner separator, the separating component is formed by extending the front end face of the insertion part along the axial direction, and is an integral structure.

[0011] As an improvement to the diaphragm separator, the endoscopic assembly includes an illumination component and an imaging component. The illumination end of the illumination component and the camera end of the imaging component are both located on the front end face of the insertion part. The illumination component and the illumination end, as well as the imaging component and the camera end, are connected by optical fiber tubes.

[0012] As an improvement to the aforementioned corner separator, the separating component includes a main rod, one end of which is bent to the left to form a protrusion.

[0013] As an improvement to the corner separator, the camera end is aligned with the end of the main rod.

[0014] As an improvement to the aforementioned corner separator, the main rod and the protrusion are in a perpendicular relationship.

[0015] As an improvement to the aforementioned iridocorner separator, the handle has a through hole along its axis for the optical fiber tube to pass through.

[0016] As an improvement to the aforementioned corner separator, the imaging component includes a camera serving as the imaging end. The camera is connected to an image acquisition module via the optical fiber tube for receiving images acquired by the camera. The image acquisition module is connected to a display module for real-time display of the acquired images.

[0017] The beneficial effects of this invention are as follows: the insertion part forms an angle with the lower end of the handle, making it easier for the insertion part to enter and adapt to the angle of the surgical site; the separation component at the front end of the insertion part is responsible for mechanically bluntly separating the adhered iridocorneal angle; at the same time, the endoscope component can obtain the image around the separation component, i.e. the image of the iridocorneal angle area, in real time by inserting the insertion part into the surgical site. The doctor can then perform precise iridocorneal angle separation operation by observing the captured real-time image. The use of the endoscope can avoid the impact on the operating field of view caused by poor corneal refractive status in traditional gonioscopy-assisted iridocorneal angle separation, and at the same time, it can observe the anterior iridocorneal angle structure in real time, which is convenient for the observation and operation of the iridocorneal angle.

[0018] Furthermore, since the endoscope component acquires images through the insertion part, and the separation component is positioned along the axis of the insertion part and located at the imaging center of the endoscope component, it is possible to acquire images of the separation component in contact with the corner of the room more accurately.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] like Figure 1 and Figure 2 As shown, a visual corner separator includes: a handle 1, an endoscope assembly 2, and a separation component 3. The endoscope assembly 2 includes an insertion part 21, which is connected to the lower end of the handle 1 and forms an angle. The separation component 3 is disposed on the front end face of the insertion part 21 and is arranged along the axial direction of the insertion part 21. The endoscope assembly 2 can obtain the image around the separation component 3 through the insertion part 21.

[0027] Specifically, the insertion part 21 is an endoscope insertion part 21. First, the angle separator is held by the handle 1 to ensure a stable grip. Then, the doctor inserts the insertion part 21 of the endoscope assembly 2 into the surgical site. Since the insertion part 21 forms an angle with the lower end of the handle 1, the insertion part 21 can more easily enter and adapt to the angle of the surgical site. The separation component 3 at the front end of the insertion part 21 is responsible for mechanically bluntly separating the adhered angle. At the same time, the endoscope assembly 2, through the insertion part 21 inserted into the surgical site, can capture the image around the separation component 3, that is, the image of the angle region. The doctor can then perform precise angle separation operations by observing the captured real-time image, avoiding the influence of poor corneal refractive status, and facilitating the observation and operation of the angle. Since the endoscope assembly 2 acquires the image through the insertion part 21, and the separation component 3 is set along the axis of the insertion part 21 and located at the imaging center of the endoscope assembly 2, the image of the separation component 3 in contact with the angle can be acquired more accurately.

[0028] With the clear surgical field of view provided by the endoscopic component 2, doctors can observe the anterior chamber angle structure more accurately, thereby performing more precise separation operations; the visual operation mode reduces the uncertainty and risk in the operation, especially when dealing with patients with poor corneal conditions, avoiding misoperation caused by unclear vision; the real-time displayed images enable doctors to quickly judge the progress and effect of the operation, thereby adjusting the operation strategy and improving the efficiency of the operation.

[0029] More specifically, the insertion part 21 is in the shape of a straight rod, and the total length of the separator and the insertion part 21 is 11mm, of which the length of the separator is 2mm and the length of the insertion part 21 is 9mm.

[0030] In some embodiments of this application, the angle between the insertion part 21 and the handle 1 is 140°-150 degrees. Specifically, during surgery, the surgeon needs to hold the handle 1 to accurately insert the insertion part 21 into the surgical site. Setting the angle between the insertion part 21 and the handle 1 to 140°-150 degrees allows the surgeon to maintain a comfortable grip while more easily adjusting the position and angle of the insertion part 21, thereby reaching the surgical site more accurately to adapt to the specific needs of different patients' anatomical structures and surgical sites.

[0031] In some embodiments of this application, the included angle is 145 degrees. More preferably, the insertion part 21 and the handle 1 are connected at a 145-degree angle, which facilitates entry into the anterior chamber from various points on the cornea and is not affected by the brow bone protrusion of the incision above the cornea when entering the anterior chamber.

[0032] In other embodiments, the included angle between the insertion part 21 and the handle 1 can be set to 141 degrees, 142 degrees, 143 degrees, 144 degrees, 146 degrees, 147 degrees, 148 degrees or 149 degrees as required.

[0033] In some embodiments of this application, the separating component 3 is formed by extending the front end face of the insertion part 21 along the axial direction, forming an integral structure. Specifically, the separating component 3 is an integral structure formed by extending the front end face of the insertion part 21 along the axial direction, making the separating component 3 and the insertion part 21 a single unit without additional connecting or assembly parts, making operation more convenient and eliminating concerns about loosening or detachment between components. During use, when a separation operation is required, the integrally structured separating component 3 will move or rotate along a preset path or direction to achieve the separation function. This enhances the stability of the separating component 3 during use, ensuring that the movement of the separating component 3 and the insertion part 21 is consistent, effectively reducing the error between the acquired image and the actual scene.

[0034] In some embodiments of this application, such as Figure 3 As shown, the endoscope assembly 2 includes an illumination component 22 and an imaging component. The illumination end 221 of the illumination component 22 and the imaging end of the imaging component are both located on the front end face of the insertion part 21. The illumination component 22 and the illumination end 221, as well as the imaging component and the imaging end, are connected by an optical fiber tube 24.

[0035] Specifically, the optical fiber tube 24 serves as the transmission medium for both light and image signals, ensuring signal quality and stability during transmission. The optical fiber tube 24 features high light transmittance, low loss, and strong anti-interference capabilities, making it suitable for applications requiring long-distance, high-quality signal transmission, such as endoscopes. The illumination end 221 of the illumination component 22 is located on the front surface of the insertion part 21, directly facing the area being observed. It provides a light source to illuminate the area, enabling the imaging component to capture a clear image and provide accurate diagnostic information for the doctor. The illumination component 22 and the illumination end 221 are connected via the optical fiber tube 24, transmitting the light emitted by the light source to the front surface. The camera end of the imaging component is also located on the front surface of the insertion part 21, adjacent to the illumination end 221. It captures the image of the observed area and converts it into a signal for transmission and processing. The imaging component and the camera end are also connected via the optical fiber tube 24, transmitting the captured image signal to the back-end processing system.

[0036] In some embodiments of this application, the separating component 3 includes a main rod 31, the front end of which is bent to the left to form a protrusion 32. The bent portion is bluntly designed to avoid damage to surrounding tissues. Specifically, during use, the main rod 31 serves as a support, while the protrusion 32 is used to perform the separation operation. The protrusion 32 interacts with the object being separated through contact, compression, or insertion, thereby achieving separation.

[0037] More specifically, the left side that bends to the left is the left side when the operator uses this corner separator; the length of the protrusion 32 is 1.6mm.

[0038] In some embodiments of this application, the camera end is aligned with the end of the main rod 31. Specifically, when the camera end and the end of the main rod 31 are aligned, it ensures that the camera end can be directly aligned with the area pointed to and contacted by the protrusion 32, which helps to achieve precise visual alignment and allows the camera end to capture a clear image of the operating area of ​​the protrusion 32. This enables coordination between operation and observation, improves the accuracy and efficiency of operation, and reduces the possibility of misjudgment. As a result, doctors can directly observe the contact between the separation component and the anterior chamber corner, thereby more precisely controlling the force and direction of the separation operation and avoiding unnecessary damage to surrounding tissues. Furthermore, arranging the camera end and the end of the main rod 31 on the same horizontal line can more effectively utilize space, reduce the vertical dimensions of the insertion part 21 and the separation component 3, making them more compact and easier to operate.

[0039] In some embodiments of this application, the main rod 31 and the protrusion 32 are perpendicular to each other. Specifically, the protrusion 32 is bent to the left, and the main rod 31 and the protrusion 32 form a 90-degree angle. When the main rod 31 and the protrusion 32 are bent to the left at a 90° angle, the protrusion can be kept parallel to the iris angle, which is beneficial for pressing down on the root of the iris to achieve blunt separation of the iris angle.

[0040] In some embodiments of this application, such as Figure 4 As shown, the handle 1 has a through hole 11 along its axis for the optical fiber tube 24 to pass through. Specifically, when the handle 1 has a through hole 11 along its axis for the optical fiber tube 24 to pass through, light or image signals are allowed to be transmitted through the optical fiber tube 24 inside the handle 1. The through hole 11 of the handle 1 not only provides a channel for the optical fiber tube 24, but also serves as structural support and protection, ensuring that the optical fiber tube 24 maintains a stable position inside the handle 1, avoiding damage or bending deformation during use, and improving the neatness of the angle separator by preventing the optical fiber tube 24 from being placed haphazardly.

[0041] In some embodiments of this application, the imaging component includes a camera 231 as a camera end. The camera 231 is connected to an image acquisition module 232 via an optical fiber tube 24 for receiving images acquired by the camera 231. The image acquisition module 232 is connected to a display module 233 for real-time display of the acquired images.

[0042] Specifically, camera 231, acting as the camera terminal, is responsible for capturing images of the external environment. The optical system inside camera 231 focuses external light onto the photosensitive element, forming a signal—the raw image data. The captured image data is transmitted to image acquisition module 232 via optical fiber tube 24. Optical fiber tube 24 utilizes the principle of total internal reflection to achieve efficient transmission of the light signal, ensuring the integrity and stability of the image data. Image acquisition module 232 receives the image data transmitted from the optical fiber tube 24 of camera 231 and converts it into a digital signal. This module also includes preprocessing functions such as noise reduction and image enhancement to improve image quality. The processed image data is sent to display module 233, where it is displayed in real time. Users can observe the image on display module 233 to understand the scene captured by camera 231 in real time. Display module 233 is a monitor.
