Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to a split-type hemorrhoidal artery ligation and hemorrhoid suspension surgical positioning device and its application. Background Technology

[0002] Hemorrhoids are a common anorectal disease, with lesions located in the lower rectum. It has a high incidence rate and can occur at any age. The disease is often caused by irritation of the anal cushions, leading to edema, congestion, vasodilation, and blood stasis. Patients often neglect the disease in its early stages, but once it worsens, it can severely impact their daily life and work. Currently, common treatments for hemorrhoids include surgical and conservative treatments. Hemorrhoidal artery ligation is one of the surgical treatment options currently available, characterized by a small incision, minimal pain for the patient, a short healing period, and good overall results. It involves ligating and blocking the arteries supplying the hemorrhoids, thereby reducing or eliminating blood flow to the hemorrhoids, promoting tissue shrinkage, alleviating prolapse symptoms, and helping the hemorrhoids return to their normal physiological state. During the surgery, instruments are often used to locate and ligate the hemorrhoidal arteries. The entire hemorrhoidal artery ligation procedure is performed using ultrasound analysis, which avoids damage to the muscle tissue, other blood vessels, and nerves in the surgical area, helping to prevent or reduce the possibility of bleeding. Currently, such surgeries often require the use of Doppler ultrasound and specialized anoscopes, which are complex in construction and inconvenient to use. Furthermore, the surgeries place high demands on the electrical safety and sterilization of the equipment, requiring it to remain functional under specific sterilization procedures. In addition, these products involve multiple manufacturing processes, such as material structure, circuit board, and sealing, making the production process complex, with each process significantly impacting the final product yield. Therefore, it is necessary to develop an ultrasonic Doppler detection instrument that not only meets the high requirements for electrical safety and sterilization but also accelerates production efficiency and improves product yield.

[0022] The technical solution provided in this application has the following advantages compared with existing related products and solutions: This application features a detachable outer tube design for the surgical device. Key components, including the ultrasonic transducer, light source, and other components related to circuit boards, power supply, and data transmission, are centrally integrated into the outer shell. This allows the tubular outer shell to be manufactured using conventional injection molding and extrusion molding processes, significantly simplifying the production process. Furthermore, the detachable outer shell facilitates processes such as groove creation, circuit board embedding, and sealing, reducing defect rates and accelerating production while lowering costs and improving product quality. Simultaneously, the combination of side clips / slots and locking mechanisms ensures the structural stability of the outer tube. Secondly, the design of operating windows on both the outer and inner tubes allows the surgical device to perform basic hemorrhoidal artery ligation while also providing suspension windows of different angles and sizes. This enables suspension and positioning ligation of hemorrhoids of varying sizes, further expanding the product's applications. Furthermore, to reduce the need for doctors to learn and practice with this surgical device before surgery and lower the requirements for surgical experience, this application incorporates a light-emitting component and an imaging component on the detector sleeve. These components illuminate the mucosal area to be ligated and sutured, allowing doctors to better control the needle insertion position and depth during the procedure, thus improving the success rate while minimizing damage to the mucosa. Simultaneously, optimization of the angles and other aspects of the light-emitting and imaging components ensures that the ligation and suspension window areas are illuminated, making procedures such as hemorrhoidal artery ligation and hemorrhoid suturing and suspension smoother.

Detailed Implementation

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0033] In this application, unless otherwise explicitly specified and limited, terms such as "installation," "fixing," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Furthermore, terms such as "inner side," "outer side," "upper," "lower," and "longitudinal," which indicate a certain orientation or positional relationship, are intended to indicate the orientation or positional relationship based on the accompanying drawings. They are only for the convenience of describing the scheme of this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] The split-type hemorrhoidal artery ligation and hemorrhoid suspension surgical positioning device disclosed in this application includes an outer sleeve and an inner sleeve. Both the inner and outer sleeves are hollow structures and can be inserted individually or simultaneously into the human anal canal and rectum. The rectal mucosa is supported by the outer wall of the outer sleeve. Needles, surgical sutures, and other necessary items are inserted through one end of the inner sleeve to perform surgeries such as hemorrhoidal artery ligation or hemorrhoid ligation and suspension. The inner sleeve is movably and / or rotatably disposed within the cavity of the outer sleeve. The outer sleeve has an operating window, and the inner sleeve has... The device includes an inner cannula operating window. Both the outer and inner cannula operating windows are movable or rotated to ensure they are at least partially aligned with each other at at least one operating window position. This alignment refers to the two operating windows facing the same or substantially the same direction; it can be side alignment, overlap, or bottom edge alignment. During surgery, the inner and outer cannulas can be rotated to position their operating windows in the same lateral direction, creating a larger operating window (suspension window) for suspending larger hemorrhoids. The inner or outer sheath can be rotated according to the size and shape of the hemorrhoid to align (i.e., partially overlap) the operating windows of both, thus creating a smaller side operating window (suspension window) to suspend smaller hemorrhoids. Furthermore, the two operating windows can be positioned opposite each other, forming an operating window (ligation window) of a predetermined size and shape at the bottom for hemorrhoidal artery ligation. The shape and size of the ligation window can be adjusted by modifying parameters such as the longitudinal length of the inner sheath, the size of the inner sheath operating window, and the longitudinal length of the outer sheath, and the size of the outer sheath operating window. The inner and outer sheaths are at least partially cylindrical, conical, or truncated conical structures in their longitudinal extension. This specific structure allows for better insertion into the patient's anal canal and rectum and facilitates rotation, while also helping to reduce damage to the rectal mucosa. The outer sheath extends longitudinally, forming a tubular outer shell body and a separate outer shell section, with a detachable side connection between the tubular outer shell body and the separate outer shell section. An optical unit is provided on the separate outer shell section to illuminate the cavity of the outer sheath.

[0035] The inner cannula described in this application extends longitudinally to form an open proximal end and an open distal end, while the outer cannula extends longitudinally to form an open proximal end and a closed distal end. The inner cannula is inserted into the opening at the proximal end of the outer cannula to assemble the surgical device of this application. Furthermore, surgical instruments are also inserted from the proximal end of the outer cannula. The distal end of the outer cannula is the end inserted into the patient's anal canal and rectum, and it is designed as a closed structure to avoid damage to the rectal mucosa during insertion. The operating window of the inner cannula and / or the operating window of the outer cannula are moved or rotated to position the operating windows of the inner cannula and the outer cannula in relative positions, forming a ligation window between the distal end of the inner cannula and the distal end of the operating window of the outer cannula (see attached diagram). Figure 3 Furthermore, the inner cannula operating window and / or the outer cannula operating window are moved or rotated so that the inner cannula operating window and the outer cannula operating window at least partially overlap (i.e., the outer cannula operating window is partially covered by the outer wall of the inner cannula), and a suspension window is formed between the side extensions of the inner cannula operating window and the side extensions of the outer cannula operating window; wherein, when switching between the ligation window and the suspension window, the inner cannula can be rotated alone, the inner cannula can be fixed while the outer cannula is rotated, or both can be rotated simultaneously. In this application, various gripping components with different structures and shapes, such as handles, are provided at the proximal end of the inner cannula to better perform operations such as pulling out or rotating the inner cannula. Without affecting the use of this surgical device, no special limitations are made on their specific shapes and structures.

[0036] In this application, an ultrasonic transducer mounted on the inner sleeve can be used to locate the hemorrhoidal artery under the anal canal and rectal mucosa. Specifically, the ultrasonic transducer detects, converts, and amplifies the blood flow signal of the hemorrhoids under the mucosa, thereby locating the hemorrhoidal artery. This application does not specifically limit the location of the ultrasonic transducer; it can be mounted on either the outer sleeve or the inner sleeve. The ultrasonic transducer can be powered by a battery or other components housed within the gripper or by an external power source connected to the gripper. To shorten the distance between the ultrasonic transducer and the gripper, reduce the use of conductive wiring, and mitigate potential risks associated with wiring sealing processes, it is preferable to position the ultrasonic transducer on the same side of the gripper.

[0037] The optical unit described in this application can be a wired or wireless device. By mounting the optical unit on the outer shell assembly, separate processing and production of the outer shell main body and the outer shell assembly are achieved. The device requires the outer shell assembly and the outer shell main body to be assembled before use, and they remain integrated during operation. To ensure stable assembly between the outer shell assembly and the outer shell main body, snap-fits and / or slots are provided on the sides of the outer shell assembly and the tubular outer shell main body to secure them. The side snap-fits and slots are respectively located on the outer shell assembly or the outer shell main body, and their positions are interchangeable. The shape and size of the side snap-fits match the side slots. To further improve the assembly stability between the outer shell assembly and the outer shell body, this application preferably provides a locking element at the distal end of the outer shell assembly. The locking element cooperates with a groove on the inner wall of the distal end of the closed outer sleeve to fix the outer shell assembly. In this application, the positions of the locking element and the groove can be interchanged, that is, the groove is provided at the distal end of the assembly, and the locking element is provided on the inner wall of the distal end of the outer sleeve. The two have the same shape and size, and the locking element and the groove are connected by a snap-fit ​​to achieve fixation.

[0038] The optical unit described in this application is used to irradiate the target surgical mucosal area during surgery, providing the surgeon with a better field of vision. In some preferred embodiments, the optical unit includes a light-emitting component and an imaging component. The light-emitting component can be various LED lights, diodes, transistors, or other light-emitting devices, and the imaging component can be various cameras or other devices. After the light-emitting component irradiates the target surgical area, the imaging component, such as the camera, displays the image to the operator in real time. This application does not specifically limit the display method of the operating area. It can transmit relevant images through a line connection and display them on a display screen or other component on the outer sleeve, or it can be wirelessly connected to an external display device to achieve real-time display of the image. The light-emitting component and the imaging component described in this application are installed in the mounting cavity of the outer sleeve through light guide columns. The shape and size of the mounting cavity of the outer sleeve can be determined according to the shape and size of the light-emitting component and the imaging component, as well as their placement relationship. Preferably, at least two sets of light-emitting components and imaging components are provided to irradiate different areas of the outer sleeve cavity. For details, please refer to the appendix. Figure 4 The circuit board is designed with one end bent at different angles, and two (or more) sets of light-emitting and imaging components are installed at the bends at different angles to illuminate different areas, including ligation windows and suspension windows during surgery. The light-emitting and imaging components are powered by a battery or other power supply unit mounted on an electrical control frame. The power supply unit is connected to the light-emitting / imaging components via the circuit board, which also transmits real-time images from the camera or other imaging components. The circuit board used in this invention is not specifically limited; any commercially available circuit board compatible with cameras or other components can be used.

[0039] In this application, grooves are provided on the outer casing to bury the circuit board. The shape and size of the grooves are consistent with the circuit board used. To further ensure the airtightness of the circuit board, a sealing plate is used for sealing and fixing, and the fixing method includes, but is not limited to, adhesive bonding. The electrical control frame described in this application is located on the near end of the casing. It can serve as a support structure for power supply units such as batteries, and can also serve as a gripping component for the outer casing, used for operations such as pulling out and rotating the outer casing.

This application does not specifically limit the hemorrhoid surgery performed, including but not limited to hemorrhoidal artery ligation and hemorrhoid suture suspension fixation surgery. This application does not specifically limit the specific use of the support frame of the hemorrhoid treatment device in the above-mentioned surgical procedures; it can be adjusted and used according to the specific surgical needs and operating procedures. The specific method can be based on methods well known to those skilled in the art.
