Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a suture device for eye surgery and a method of using the same. Background Art

[0002] With the continuous advancement of modern medical technology, the proportion of ophthalmic surgery in clinical treatment has increased year by year, especially in the treatment of diseases such as cataracts, glaucoma, retinal detachment and corneal transplantation, surgery has become the main means of intervention. Eye surgery usually involves delicate tissue manipulation and high-precision suturing processes. Especially in the suturing of the surface of the eyeball or the tissue inside the eye, the doctor must operate in an extremely small operating space. The operation is difficult, the operation time is long, and the operating skills of the surgeon are extremely high. Traditional ophthalmic suturing operations mostly rely on manual suturing with the assistance of a microscope, which is not only time-consuming, but also prone to uneven suturing tension or tissue damage due to unstable manual operation, thereby affecting the postoperative recovery effect, and even leading to complications such as bleeding, infection, scar hyperplasia and other problems at the suture site. Therefore, the development of an eye surgery suturing device that can improve surgical efficiency, reduce tissue trauma, and ensure suturing uniformity and stability has important clinical application value.

[0003] Currently, some minimally invasive suturing devices are being marketed for use in ophthalmology, such as micro-automatic suturing devices and tissue adhesives as an alternative to sutures. However, these solutions still have limitations. While automated suturing devices improve operational efficiency, they are prone to over-deep suturing or uneven clamping force when applied to delicate ocular tissues. Furthermore, their complex structure makes it difficult to precisely control intraocular tissue. While tissue adhesives can reduce the need for sutures, their biocompatibility, safety, and long-term fixation remain controversial, and they cannot provide sufficient tissue fixation strength in certain types of ophthalmic surgery.

[0004] In view of the above situation, in order to overcome the above technical problems, the present invention designs a suture device for eye surgery and a method of using the same, which solves the above technical problems. Summary of the Invention

[0005] The technical purpose to be achieved by the present invention is to design a suture device for eye surgery and a method of using the same, which can suture the wound quickly and stably, avoiding the situation of unstable suturing caused by doctors working for a long time and reducing work intensity.

[0006] In order to achieve the above technical objectives, the present invention provides the following technical solutions:

[0007] A suture device for ophthalmic surgery mainly comprises a drive mechanism, a housing assembly, a mating block, and a suturing assembly. The suture device has a compact structure and a rational design, and is intended to improve operational stability and suturing accuracy during surgery. A housing assembly is mounted on the side of the drive mechanism to protect the internal structure and provide operational support; a mating block is mounted on the other side of the housing assembly to assist in positioning during surgery and ensure precise alignment of the suture device on the ocular tissue. The suturing assembly is mounted on one end of the drive mechanism and is the key execution unit for performing the actual suturing action. It can quickly and stably implant sutures or staples into the tissue during operation to achieve tissue closure.

[0008] The internal structure of the driving mechanism is relatively complex, consisting of a driving component, a connecting component, a pushing cross block and a mounting component. Among them, the driving component is the core power source of the entire mechanism, mainly used to provide the power required for the suturing action; the connecting component is installed on the side of the driving component, used to transmit the drive to the subsequent mechanism; the pushing cross block is installed on the side of the connecting component as a motion conversion unit, which can further accurately transmit the rotational or linear motion; and the mounting component is fixed on the side of the pushing cross block, which is used to stably install the suturing component thereon. After the driving component is started, it drives the connecting component to rotate or advance, thereby causing the pushing cross block to produce a corresponding displacement, and then drives the suturing component to move along the set trajectory toward the inside of the outer shell component to complete the tissue suturing operation. The device can operate flexibly in a narrow surgical space, improving the suturing efficiency and safety in eye surgery.

[0009] The driving assembly mainly includes a driving motor, a rotating shaft, a rotating disk and a driving block, which constitute the power core of the entire suturing device. The driving motor is arranged inside the driving assembly, and is used to provide stable and controllable power output. It is the main power source for the operation of the entire device. The rotating shaft is installed on the side of the driving motor, and is used to effectively transmit the rotational power of the motor to the subsequent structure. The rotating disk is fixed to one end of the rotating shaft and rotates with the rotating shaft, playing the role of connection and transmission. The driving block is installed on the side of the rotating disk and is distributed in a circular array. This structural arrangement can not only achieve uniform power distribution, but also improve the coordination and stability of the suturing action, effectively avoid the deviation or tissue damage caused by uneven force distribution during the suturing process, and ensure that the suturing assembly always maintains balanced operation during the pushing process.

[0010] The connecting assembly includes a connecting block, a telescopic slot and a drive card slot, which are mainly used to transmit and buffer the kinetic energy during the driving process, and at the same time realize the stable connection of the suture device structure. The connecting block is installed on the outside of the rotating shaft, and acts as a bridge connecting the driving mechanism and the subsequent components, and can move synchronously under the drive of the rotating shaft. A telescopic slot is provided inside the connecting block. This structure can produce a certain elastic stroke during the driving process, play a buffering and adjustment role, and effectively avoid structural damage caused by excessive driving force or sudden changes. A drive card slot is further provided inside the telescopic slot for transmission with the drive card block. The cross-sectional shape of the drive card slot is designed to be rectangular. This structure helps to enhance the stability of the engagement and the uniformity of force, avoid slippage or rotation errors, thereby ensuring the precise advancement of the suturing assembly during operation and providing reliable motion control guarantee for eye surgery.

[0011] A magnetic groove is located at the center of the side of the push cross block, which is used to embed magnetic elements to enhance the adsorption and fixation between components. A magnetic block is also located at the corresponding position on the side of the push cross block. The magnetic interaction between the block and the groove allows for rapid positioning and secure connection of the suture components during movement, helping to improve the stability and reliability of the structure.

[0012] The installation assembly includes an installation chuck, an installation cross block, an installation magnetic groove and an installation magnetic block, which are mainly used to achieve a stable connection and quick assembly between the suturing assembly and the driving structure. The installation chuck is fixedly arranged on the side of the pushing cross block, serving as the basic support platform for the installation assembly to ensure that the entire assembly has good stability during movement. The installation cross block is installed on the side of the installation chuck and is arranged in a cross-shaped structure, which helps to disperse the force and enhance the installation stability and anti-rotation ability. The installation magnetic groove is opened on the upper surface of the installation cross block for embedding magnetic connection components, which realizes the rapid positioning and disassembly of the suturing assembly through magnetic force, thereby improving operational efficiency. The installation magnetic block is embedded in the middle position of the installation cross block, corresponding to the magnetic structure in the pushing cross block, forming a reliable magnetic connection. This design not only improves the convenience of the installation process, but also ensures that the suturing assembly is not easy to fall off or loosen during movement, thereby enhancing the safety and practicality of the overall structure.

[0013] The surfaces of both the push and mount magnetic slots are made of magnetic material to enhance the magnetic connection between the components. The push and mount magnetic blocks have opposite polarities, while the push and mount magnetic blocks have opposite polarities. This allows for strong adhesion between the two, ensuring the stability and reliability of the suture assembly during installation and operation, and preventing loosening or falling off.

[0014] The housing assembly includes a suturing cover, a fitting block, a fitting surface, and a guide groove, which are primarily used to protect the internal structure and guide the precise movement of the suturing assembly within the ocular tissue. The suturing cover is mounted on the side of the drive mechanism, and the overall structure is designed in a stepped terrace shape, which helps enhance its stability and pressure resistance while leaving sufficient space for the internal components to move. A fitting block is mounted at the bottom of the suturing cover for initial contact and positioning with the surface of the ocular tissue, ensuring accurate alignment of the device during the suturing process. A fitting surface is provided below the fitting block, which is designed to have an arc-shaped structure that fits the natural curve of the eyeball or tissue, effectively reducing the sense of pressure and improving the comfort and safety of the surgery. The guide groove is provided on the inner surface of the suturing cover and is configured in a conical spiral shape. It can be used to guide the suturing assembly to move smoothly along a specific path, preventing deviation or jamming during operation, while improving the uniformity of the suturing and the controllability of the operation. The structural design of the housing assembly combines functionality and biocompatibility, making it suitable for delicate ophthalmic surgical operations.

[0015] The suturing assembly includes a fixed disk, a cross groove, a suture thread and a suture needle, which constitute the key actuator for suturing eye tissue. The fixed disk is installed on the side of the driving mechanism, and plays the role of connecting and supporting the suture structure to ensure the stability of the suturing assembly during movement. A cross groove is provided on the fixed disk, which is used to cooperate with the cross block of the mounting assembly to achieve precise positioning and reliable connection. One end of the suture thread is fixedly mounted on the fixed disk, and the other end is connected to the suture needle. The suture needle adopts a fine-point structure design, which can smoothly penetrate the eye tissue and reduce the area of ​​trauma. This structure enables the suture needle to run along the set trajectory under the driving action, driving the suture thread to complete the puncture and suturing process. It is suitable for the high-precision suturing requirements of delicate tissues in ophthalmic surgery, and improves surgical efficiency and suture quality.

[0016] The suture is made of a material with good elasticity, which can effectively buffer the tension during the tissue suturing process and reduce the pulling damage to the eye tissue. The suture is made of a biodegradable and soluble thread, which does not need to be removed after surgery and can be naturally absorbed within a certain period of time after surgery, effectively reducing the risk of postoperative infection. The overall spiral structure design of the suture helps to enhance the fixing force and stability during the suturing process, so that the suture is more firmly embedded in the tissue, improving the suturing effect. It is especially suitable for precision surgical scenarios such as the eye, which have high suturing requirements.

[0017] A method for using a suture device for eye surgery, the method being used in conjunction with the above-mentioned suture device for eye surgery; the method is characterized in that the steps of the method are as follows:

[0018] S1: The operator disinfects various components and uses clean tools to install the new suture on the fixed disk and install the suture needle on the other end;

[0019] S2: Install the fixed plate on the pushing cross block through the cross slot, install the mounting chuck on the side of the pushing cross block, push the magnetic groove and the mounting magnetic block to attract and fix each other, push the magnetic block and the mounting magnetic groove to attract and fix each other, and thus install the fixed plate at one end of the drive assembly;

[0020] S3: The housing assembly is placed at the site where surgery is required, with the fitting surface aligned with the skin on both sides of the wound, and the driving motor in the driving assembly is started, so that the driving motor drives the rotating shaft to rotate;

[0021] S4: The rotating disk installed on the rotating shaft rotates, and the driving card block is connected to the driving card slot, thereby causing the connecting block to rotate, and further driving the fixed block to rotate;

[0022] S5: As the suture thread rotates under the drive of the fixed disk, the suture needle drives the suture thread to perform suturing work under the cooperation of the spiral guide groove.

[0023] The beneficial effects of the present invention are as follows:

[0024] (1) The present invention realizes efficient, stable and precise control of suturing action by rationally designing the driving mechanism and suturing assembly. The internal structure of the driving mechanism is compact, and the motor is used to drive the rotating shaft to drive the rotating disk and the driving block, so that the suturing assembly can move smoothly in the narrow eye surgical space, effectively avoiding the problems of uneven suturing and tissue damage caused by unstable operation during traditional manual suturing. At the same time, the precise matching design of the connecting assembly and the pushing cross block ensures the accuracy of the movement path and improves the repeatability and reliability of the suturing process. Through the application of the magnetic adsorption structure, the suturing assembly can be quickly assembled and disassembled and firmly connected, which is convenient for the doctor's operation and avoids the loosening or dislocation of the suturing device during movement, greatly improving the efficiency and safety of the operation.

[0025] (2) The present invention uses dissolvable elastic sutures, combined with a spiral suture structure design, which can effectively reduce postoperative foreign body sensation and tissue rejection, avoid the discomfort and infection risk of suture removal, and promote natural wound healing and recovery. The design of the outer shell component with a curved fitting surface fully considers the curvature of the eyeball surface, allowing the suture device to better fit the eyeball tissue, reducing pressure and irritation on the tissue, and helping to improve the comfort and satisfaction of the patient after surgery.

DETAILED DESCRIPTION

[0038] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0039] like Figure 1-9As shown, a suturing device for eye surgery mainly includes a driving mechanism 1, a shell assembly 2, a matching block 3 and a suturing assembly 4. The suturing device has a compact structure and a reasonable design, and is intended to improve operational stability and suturing accuracy during surgery. A shell assembly 2 is installed on the side of the driving mechanism 1 to protect the internal structure and provide operational support; a matching block 3 is installed on the other side of the shell assembly 2, and the matching block 3 is used to assist in positioning during surgery to ensure that the suturing device is accurately aligned on the eye tissue. The suturing assembly 4 is installed at one end of the driving mechanism 1. It is the key execution unit for completing the actual suturing effect. It can quickly and stably implant sutures or staples into the tissue during operation to achieve tissue closure.

[0040] like Figure 2 As shown, the internal structure of the driving mechanism 1 is relatively complex, and is composed of a driving component 11, a connecting component 12, a pushing cross block 13 and a mounting component 14. Among them, the driving component 11 is the core power source of the entire mechanism, mainly used to provide the power required for the suturing action; the connecting component 12 is installed on the side of the driving component 11, and is used to transmit the drive to the subsequent mechanism; the pushing cross block 13 is installed on the side of the connecting component 12 as a motion conversion unit, which can further accurately transmit the rotational or linear motion; and the mounting component 14 is fixed on the side of the pushing cross block 13, and is used to stably mount the suturing component 4 thereon. After the driving component 11 is started, it drives the connecting component 12 to rotate or advance, thereby causing the pushing cross block 13 to produce a corresponding displacement, thereby driving the suturing component 4 to move along the set trajectory toward the inside of the shell component 2 to complete the tissue suturing operation. The device can operate flexibly in a narrow surgical space, improving the suturing efficiency and safety in eye surgery.

[0041] like Figure 3 As shown, the drive assembly 11 mainly includes a drive motor 111, a rotating shaft 112, a rotating disk 113 and a driving block 114, which constitute the power core of the entire suture device. The drive motor 111 is arranged inside the drive assembly 11, and is used to provide stable and controllable power output. It is the main power source for the operation of the entire device. The rotating shaft 112 is installed on the side of the drive motor 111, and is used to effectively transmit the rotational power of the motor to the subsequent structure. The rotating disk 113 is fixed to one end of the rotating shaft 112 and rotates with the rotating shaft 112, playing the role of connection and transmission. The driving block 114 is installed on the side of the rotating disk 113 and is distributed in a circular array. This structural arrangement can not only achieve uniform power distribution, but also improve the coordination and stability of the suturing action, effectively avoid offset or tissue damage caused by uneven force distribution during the suturing process, and ensure that the suturing assembly 4 always maintains balanced operation during the pushing process.

[0042] like Figure 4As shown, the connecting assembly 12 includes a connecting block 121, a telescopic slot 122, and a drive card slot 123, which are mainly used to transmit and buffer the kinetic energy during the driving process, while achieving a stable connection of the suture device structure. The connecting block 121 is installed on the outside of the rotating shaft 112, acting as a bridge connecting the drive mechanism 1 and subsequent components, and can move synchronously under the drive of the rotating shaft 112. The connecting block 121 is internally provided with a telescopic slot 122. This structure can generate a certain elastic stroke during the driving process, playing a buffering and adjustment role, and effectively avoiding structural damage caused by excessive driving force or sudden changes. The telescopic slot 122 is further provided with a drive card slot 123 for cooperating with the drive card block 114 for transmission. The cross-sectional shape of the drive card slot 123 is designed to be rectangular. This structure helps to enhance the stability of the engagement and the uniformity of the force, avoid slippage or rotational errors, thereby ensuring the precise advancement of the suturing assembly 4 during operation, providing reliable motion control guarantee for eye surgery.

[0043] like Figure 6 As shown, a magnetic groove 131 is provided at the center of the side of the push cross block 13. This groove is used to embed a magnetic element to enhance the adsorption and fixation between components. A magnetic block 132 is also provided at a corresponding position on the side of the push cross block 13. The magnetic interaction between the magnetic block and the magnetic groove enables rapid positioning and secure connection of the suture component 4 during movement, helping to improve the stability and reliability of the structure's operation.

[0044] like Figure 7 As shown, the mounting assembly 14 includes a mounting chuck 141, a mounting cross block 142, a mounting magnetic groove 143, and a mounting magnetic block 144, which are mainly used to achieve a stable connection and quick assembly between the suturing assembly 4 and the drive structure. The mounting chuck 141 is fixedly set on the side of the pushing cross block 13, serving as the basic support platform of the mounting assembly 14, ensuring that the entire assembly has good stability during movement. The mounting cross block 142 is installed on the side of the mounting chuck 141 and arranged in a cross-shaped structure, which helps to disperse the force and enhance the installation stability and anti-rotation ability. The mounting magnetic groove 143 is opened on the upper surface of the mounting cross block 142 for embedding magnetic connection components, which realizes the rapid positioning and disassembly of the suturing assembly 4 through magnetic force, thereby improving operational efficiency. The mounting magnetic block 144 is embedded in the middle position of the mounting cross block 142, corresponding to the magnetic structure in the pushing cross block 13, forming a reliable magnetic connection. This design not only improves the convenience of the installation process, but also ensures that the suturing assembly 4 is not easy to fall off or loosen during movement, thereby enhancing the safety and practicality of the overall structure.

[0045] The surfaces of the push magnetic groove 131 and the mounting magnetic groove 143 are both made of magnetic material to enhance the magnetic connection between the components. The magnetic poles of the push magnetic groove 131 and the mounting magnetic block 144 are set to opposite polarity, and the magnetic poles of the push magnetic block 132 and the mounting magnetic groove 143 are also set to opposite polarity, thereby achieving strong adhesion between them, ensuring the stability and reliability of the suture assembly 4 during installation and operation, and preventing loosening or falling off.

[0046] like Figure 8 As shown, the shell assembly 2 includes a suturing cover 21, a fitting block 22, a fitting surface 23 and a guide groove 24, which are mainly used to protect the internal structure and guide the precise movement of the suturing assembly 4 in the eye tissue. The suturing cover 21 is installed on the side of the driving mechanism 1, and the overall structure is designed in a stepped shape, which helps to enhance its stability and pressure resistance, while reserving sufficient space for the internal components to move. A fitting block 22 is installed at the bottom of the suturing cover 21 for initial contact and positioning with the surface of the eye tissue to ensure the accurate alignment of the device during the suturing process. A fitting surface 23 is provided below the fitting block 22. The fitting surface 23 is designed as an arc structure, which fits the natural curve of the eyeball or tissue, can effectively reduce the sense of oppression and improve the comfort and safety of the operation. The guide groove 24 is opened on the inner surface of the suturing cover 21, and the structure is set to be conical spiral, which can be used to guide the suturing assembly 4 to move smoothly along a specific path, prevent offset or jamming during operation, and improve the uniformity of suturing and the controllability of operation. The structural design of the housing component 2 is both functional and biocompatible, and is suitable for delicate ophthalmic surgical operations.

[0047] like Figure 9 As shown, the suturing assembly 4 includes a fixed disk 41, a cross groove 42, a suture 43 and a suture needle 44, which constitute the key executive mechanism for realizing eye tissue suturing. The fixed disk 41 is installed on the side of the driving mechanism 1, and plays the role of connecting and supporting the suture structure to ensure the stability of the suturing assembly 4 during movement. A cross groove 42 is provided on the fixed disk 41, which is used to cooperate with the cross block of the mounting assembly 14 to achieve precise positioning and reliable connection. One end of the suture 43 is fixedly mounted on the fixed disk 41, and the other end is connected to the suture needle 44. The suture needle 44 adopts a fine-pointed structure design, which can smoothly penetrate the eye tissue and reduce the area of ​​trauma. This structure enables the suture needle 44 to run along the set trajectory under the driving action, driving the suture 43 to complete the puncture and suturing process, which is suitable for the high-precision suturing requirements of delicate tissues in ophthalmic surgery, and improves surgical efficiency and suturing quality.

[0048] The suture 43 is made of a material with excellent elasticity, which can effectively buffer the tension during the tissue suturing process and reduce traction damage to the eye tissue. The suture 43 is made of a biodegradable and soluble material, which does not require postoperative suture removal and can be naturally absorbed within a certain period of time after surgery, effectively reducing the risk of postoperative infection. The overall spiral structure design of the suture 43 helps to enhance the fixation and stability during the suturing process, allowing the suture to be more firmly embedded in the tissue and improving the suturing effect. It is particularly suitable for precision surgical scenarios such as the eye, which require high suturing requirements.

[0049] A method for using a suture device for eye surgery, the method being used in conjunction with the above-mentioned suture device for eye surgery; the method is characterized in that the steps of the method are as follows:

[0050] S1: The operator sterilizes various components and uses clean tools to install a new suture thread 43 on the fixed plate 41 and installs a suture needle 44 on the other end;

[0051] S2: Install the fixed plate 41 on the pushing cross block 13 through the cross slot 42, install the mounting chuck 141 on the side of the pushing cross block 13, push the magnetic groove 131 and the mounting magnetic block 144 to attract and fix each other, push the magnetic block 132 and the mounting magnetic groove 143 to attract and fix each other, thereby installing the fixed plate 41 at one end of the driving assembly 11;

[0052] S3: The housing assembly 2 is placed at the site where surgery is required, with the fitting surface 23 aligned with the skin on both sides of the wound, and the driving motor 111 in the driving assembly 11 is started, so that the driving motor 111 drives the rotating shaft 112 to rotate;

[0053] S4: The rotating disk 113 mounted on the rotating shaft 112 rotates, and the driving block 114 is engaged in the driving slot 123, thereby causing the connecting block 121 to rotate, further driving the fixed block to rotate;

[0054] S5: As the suture thread 43 rotates under the drive of the fixed disk 41 , the suture needle 44 drives the suture thread 43 to perform suturing under the cooperation of the spiral guide groove 24 .

[0055] During the working process of the present invention, the operator first strictly disinfects the various components of the stapler to ensure that all components are sterile before use to prevent intraoperative infection. Subsequently, a special clean tool is used to install the new suture 43 on the fixed disk 41, and the other end of the suture 43 is fixed with the suture needle 44 to ensure that the suture needle 44 is firmly connected to the suture 43 so that the suturing operation can be completed smoothly. Next, the fixed disk 41 equipped with the suture 43 and the suture needle 44 is accurately installed on the pushing cross block 13 through the cross groove 42 thereon, and the mounting chuck 141 is fixed to the side of the pushing cross block 13. The pushing magnetic suction groove 131 and the mounting magnetic suction block 144 are attracted to each other by magnetic force to achieve a firm fixation, ensuring that the fixed disk 41 can be firmly installed on one end of the driving component 11 to avoid loosening or falling off during movement.

[0056] After completing the above installation, the outer shell component 2 is accurately placed on the eye area that requires surgery, ensuring that the fitting surface 23 fits tightly against the skin on both sides of the wound, and ensuring the stability and positioning accuracy of the device during the suturing process. Start the drive motor 111 in the drive component 11, and the motor starts to rotate, driving the rotating shaft 112 to operate. The rotating disk 113 installed on the rotating shaft 112 rotates accordingly, and the driving card block 114 is firmly engaged with the driving card slot 123 in the connecting block 121, so that the connecting block 121 rotates synchronously, thereby pushing the fixed disk 41 to rotate accordingly. Since the fixed disk 41 drives the suture thread 43 to rotate, under the precise guidance of the spiral guide groove 24, the suture needle 44 moves in an orderly manner with the suture thread 43 to complete the fine suturing operation on the eye tissue. The whole process is efficient and precise, which greatly improves the suturing quality and safety of eye surgery.
