Description

Technical Field

[0001] This invention relates to the field of surgical medical supplies technology, and more particularly to an absorbable surgical barbed suture assembly. Background Technology

[0002] Surgical sutures are threads used by surgeons to suture tissues together. They can be used to close wounds caused by trauma or surgical incisions, and can also be used to ligate blood vessels. Currently, commonly used surgical sutures both domestically and internationally can be divided into non-absorbable surgical sutures and absorbable surgical sutures based on their biodegradability.

[0003] Non-absorbable surgical sutures do not degrade in the body and cannot be absorbed by tissues, resulting in varying degrees of tissue reaction. They require suture removal after suturing and are prone to leaving scars when used for suturing the epidermis. Absorbable surgical sutures, made from glycolide, glycolol, cyclopropane carbonate, and lactide, are suitable for suturing and ligating general soft tissues, but cannot be used in neurosurgery, cardiovascular surgery, etc. They can completely degrade or be absorbed by tissues in the body, exhibiting minimal reaction with body tissues. Suture removal is not required after suturing. Due to their various beneficial properties, absorbable surgical sutures have been widely used in surgical procedures and have a promising future.

[0004] Absorbable sutures typically have barbs on their surface. When using them, the doctor simply passes the suture through the tissue to be sutured and then pulls it tight. Because of the barbs, they firmly grip the tissue, preventing slippage. This design makes the suturing process simpler and faster, while also reducing surgical time and bleeding. These barbs firmly grip the tissue during suturing, eliminating the need for knotting and simplifying the procedure. However, when cutting the suture according to the wound, the barbs are so small that they can easily be cut. If a barb is cut, the suture may loosen due to slight tissue movement during wound healing, resulting in insufficient suture strength. Furthermore, cutting the barbs can make the suture surface uneven, easily trapping bacteria and tissue debris. These contaminants can create a potential source of infection at the wound site, increasing the chance of infection. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that the barbs in the prior art are easily cut off, which affects the quality of sutures, and to propose an absorbable surgical barb suture assembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an absorbable surgical barbed suture assembly, including a suture collection box, a delivery box being fixedly connected through the outer wall of the suture collection box, and a bidirectional screw being rotatably connected through the inner wall of the delivery box, and a movable plate being threadedly connected to the outer wall of the bidirectional screw.

[0007] The inner wall of the conveying box is provided with a cutting mechanism to cut the sewing thread at an angle when taking the thread.

[0008] The outer wall of the take-up box is provided with a clamping mechanism to clamp and fix the sewing thread when it is cut.

[0009] Furthermore, the cutting mechanism includes several fixed blocks, each with a through-groove on its sidewall. A sliding rod is slidably connected between the inner walls of two corresponding sliding grooves, and a cutter is fixedly connected to the outer wall of the sliding rod. A first spring is fixedly connected between two sliding rods. A sliding block is slidably connected to the end of the moving plate, and a tension spring is fixedly connected to one end of the sliding block. The end of the tension spring away from the sliding block is fixedly connected to the inside of the moving plate, and a locking block is fixedly connected to the end of the sliding block away from the tension spring.

[0010] Furthermore, the sidewalls of several of the fixing blocks are fixedly connected to the inner wall of the conveying box, the bottom of the locking block corresponds to the outer wall of the slide bar, and the blades of the two cutters correspond to each other.

[0011] Furthermore, the clamping mechanism includes several connecting plates. A first connecting rod is fixedly connected between the side walls of two corresponding connecting plates. A first clamping block is fixedly connected to the outer wall of each of the two first connecting rods. The clamping ends of the two first clamping blocks correspond to each other. A third sliding groove is formed through the side wall of the connecting plate. A second connecting rod is slidably connected between the inner walls of two corresponding third sliding grooves. A second clamping block is fixedly connected to the outer wall of each of the two second connecting rods. The clamping ends of the two second clamping blocks correspond to each other. A second spring is fixedly connected between two connecting plates on the same side of the conveying box. A pressing rod is fixedly connected to the side of the connecting plate away from the second spring.

[0012] Furthermore, the end of the conveying box away from the take-up box has a discharge port, the side wall of the conveying box has a first groove, and the side wall of the conveying box has a second groove.

[0013] Furthermore, the side wall of the connecting plate is slidably connected to the outer wall of the conveying box, the outer wall of the first connecting rod is slidably connected to the inner wall of the first chute, the outer wall of the second connecting rod is slidably connected to the inner wall of the second chute, and the outer wall of the first clamping block is slidably connected through the inner wall of the discharge port.

[0014] Furthermore, a limiting block is fixedly connected to the end of the movable plate away from the card block, and a limiting groove is formed through the side wall of the limiting block, and the outer wall of the second connecting rod is slidably connected to the inner wall of the limiting groove.

[0015] Furthermore, a protective cover is rotatably connected to one side wall of the conveying box, and the end of the extrusion rod away from the connecting plate corresponds to the outer wall of the protective cover.

[0016] Furthermore, a button is fixedly installed on the outer wall of the conveying box at a position corresponding to the inside of the protective cover, and the button is electrically connected to the motor. A cover plate is installed on the side wall of the take-up box.

[0017] Compared with existing technologies, the above solution has the following advantages:

[0018] 1. When sutures are needed, the rotation of the bidirectional screw will cause the two moving plates to shift in opposite directions, causing the two cutters to shift relative to each other. This allows the cutters to squeeze and cut the outer wall of the suture through their blades. Because the cutters are designed to be angled, they will cut at an angle during the cutting process. This angled cutting avoids cutting through the barbs on the suture, ensuring that the suture can still perform its proper sewing and fixing functions after cutting. This ensures the quality of the suture during subsequent use and also prevents the barbs from being cut into fragments and scattered everywhere.

[0019] 2. When sutures need to be cut, flipping the protective cover causes the two first clamping blocks to move closer to each other, clamping the outer wall of the suture end. At the same time, the second connecting rod causes the two second clamping blocks to move closer to each other, clamping the outer wall of the suture end to be cut. During this process, the suture is always clamped, ensuring that the suture remains stable during cutting. This allows for accurate cutting of the suture along a predetermined trajectory, avoiding cutting errors caused by suture movement, ensuring the accuracy and consistency of the cut, improving the precision of the surgical operation, and preventing the suture from swinging randomly during the cutting process, which would affect the cutting effect.

[0020] 3. After the suture is cut, the first clamping block maintains its clamping function on the suture. When the operator needs to remove the suture, the protective cover is flipped to reset it. At this time, the protective cover no longer squeezes the compression rod. Then, the elastic force generated by the compression of the second spring drives the two connecting plates to slide away from each other. Only then will the first clamping block release its function on the suture. The clamping of the suture is controlled by opening and closing the protective cover. When the protective cover is open, the cut suture cannot be removed. Only when the protective cover is closed can the cut suture be removed. This prevents the situation of forgetting to close the cover and ensures that the suture is not accidentally cut, thus avoiding waste of suture.

[0021] 4. During the clamping process before cutting the thread, the displacement of the moving plate causes the second connecting rod to slide along the inside of the second groove. Since the second clamping block is already holding the thread, the second connecting rod will stretch the thread during its displacement, thus smoothing it out. This stretching also helps the cutting process proceed smoothly. After cutting, the second connecting rod will move the new end of the thread past the blade and into the outlet during its reset process. This allows the thread to be automatically transported a distance after cutting, preventing the operator from crossing the blade side and directly touching the thread area, thus avoiding injury. Furthermore, no additional drive is required, improving the convenience of thread retrieval and cutting. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] In the description of this invention, it should be understood that the terms "upper," "lower," "top surface," "bottom surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are only used to distinguish an entity or operation from another entity or operation, and do not require or imply any actual relationship, order, or relative importance between these entities or operations.

[0032] Example 1, please refer to Figures 1-3 An absorbable surgical barbed suture assembly includes a suture take-up box 1, a delivery box 2 is fixedly connected to the outer wall of the suture take-up box 1, and a bidirectional screw 3 is rotatably connected to the inner wall of the delivery box 2. A movable plate 4 is threadedly connected to the outer wall of the bidirectional screw 3. A discharge port 8 is provided at one end of the delivery box 2 away from the suture take-up box 1. A first groove 9 and a second groove 10 are provided on the side wall of the delivery box 2.

[0033] More specifically, the take-up box 1 provides storage for the sewing thread. Since the cover 15 is detachable, the cover 15 is first removed, and then the rolled sewing thread is placed inside the take-up box 1. At the same time, the outer end of the sewing thread is passed through the inside of the conveyor box 2 to the inside of the outlet 8. After that, the cover 15 is reinstalled and fixed to the side wall of the take-up box 1, thus completing the installation of the sewing thread. When the sewing thread is not needed, the internal space of the take-up box 1 can also provide favorable conditions for storing the sewing thread.

[0034] Example 2, please refer to Figures 2-4 Based on Embodiment 1, in this embodiment, the inner wall of the conveying box 2 is provided with a cutting mechanism 5, and a protective cover 13 is rotatably connected to the corresponding side wall of the conveying box 2. The end of the extrusion rod 608 away from the connecting plate 601 corresponds to the outer wall of the protective cover 13. A button 14 is fixedly installed at the corresponding position of the outer wall of the conveying box 2 and the inside of the protective cover 13, and the button 14 is electrically connected to the motor 7. A cover plate 15 is installed on the side wall of the take-up box 1.

[0035] Furthermore, the cutting mechanism 5 includes several fixed blocks 501, each of which has a through groove 502 extending through its sidewall. A slide rod 503 is slidably connected between the inner walls of two corresponding grooves 502, and a cutter 504 is fixedly connected to the outer wall of the slide rod 503. A first spring 505 is fixedly connected between the two slide rods 503. A sliding block 506 is slidably connected to the end of the moving plate 4, and a tension spring 507 is fixedly connected to one end of the sliding block 506. The end of the tension spring 507 away from the sliding block 506 is fixedly connected to the inside of the moving plate 4. A locking block 508 is fixedly connected to the end of the sliding block 506 away from the tension spring 507. The sidewalls of the several fixed blocks 501 are fixedly connected to the inner wall of the conveying box 2. The bottom of the locking block 508 corresponds to the outer wall of the slide rod 503, and the blades of the two cutters 504 correspond to each other.

[0036] More specifically, when sewing is needed, first pull the end of the sewing thread inside the discharge port 8 outward. The sewing thread will then extend outward. When the sewing thread extending out of the conveyor box 2 reaches the required length, it needs to be cut. At this time, manually flip the protective covers 13 located on the upper and lower sides of the conveyor box 2 simultaneously. Then, the buttons 14 inside the protective covers 13 will be exposed. Then, by pressing the two buttons 14 at the same time, the drive motor 7 is triggered. The output shaft of the motor 7 will drive the bidirectional screw 3 to rotate synchronously. Since the outer wall of the bidirectional screw 3 is designed with bidirectional threads, the rotation of the bidirectional screw 3 will drive the two moving plates 4 to move in opposite directions. Then, the moving plates 4 will drive the sliding block 506 to move synchronously. At the same time, the sliding block 506 will drive the locking block 508 to move synchronously.

[0037] When the moving plate 4 moves to the designated position, the locking block 508 will contact the slide rod 503. Then, the locking block 508 will engage with the outer wall of the slide rod 503 through the bottom. During the subsequent movement, the locking block 508 will squeeze the outer wall of the slide rod 503, causing the slide rod 503 to slide along the inner wall of the inclined groove 502. During the sliding of the slide rod 503, the locking block 508 will drive the tension spring 507 to be stretched through the sliding block 506, which can ensure that the locking block 508 is always engaged with the outer wall of the slide rod 503. At the same time, the slide rod 503 will drive the cutter 504 to move synchronously. At this time, through the relative displacement of the two cutters 504, the outer wall of the seam is squeezed and cut through the blade of the cutter 504. During the process, the first spring 505 will be compressed.

[0038] Because the cutter 504 is designed to be angled, it will cut at an angle during the cutting process. This angled cutting avoids cutting the barbs on the suture, ensuring that the suture can still perform its proper suturing and fixing functions after cutting.

[0039] Then, when the blades of the two cutters 504 come together, the cutting of the thread is completed. Next, the control motor 7 drives the bidirectional screw 3 to reverse, causing the moving plate 4 to move back to its original position. Then, the locking block 508 gradually reduces the force applied to the slide rod 503. Then, the tension of the tension spring 507 drives the locking block 508 to move back to its original position. After that, the slide rod 503 is released by the force generated by the compression of the first spring 505. While moving back to its original position, the cutter 504 is disengaged from the thread, thus completing the oblique cutting of the thread.

[0040] Example 3, please refer to Figures 5-6 Based on Embodiment 2, in this embodiment, the outer wall of the take-up box 1 is provided with a clamping mechanism 6.

[0041] Furthermore, the clamping mechanism 6 includes several connecting plates 601. A first connecting rod 602 is fixedly connected between the side walls of two corresponding connecting plates 601. A first clamping block 603 is fixedly connected to the outer wall of each of the two first connecting rods 602. The clamping ends of the two first clamping blocks 603 correspond to each other. A third sliding groove 604 is formed through the side wall of the connecting plate 601. A second connecting rod 605 is slidably connected between the inner walls of two corresponding third sliding grooves 604. A second clamping block 605 is fixedly connected to the outer wall of each of the two second connecting rods 605. 6. The clamping ends of the two second clamping blocks 606 correspond to each other. A second spring 607 is fixedly connected between the two connecting plates 601 on the same side of the conveying box 2. A pressing rod 608 is fixedly connected to the side of the connecting plate 601 away from the second spring 607. The side wall of the connecting plate 601 is slidably connected to the outer wall of the conveying box 2. The outer wall of the first connecting rod 602 is slidably connected to the inner wall of the first slide groove 9. The outer wall of the second connecting rod 605 is slidably connected to the inner wall of the second slide groove 10. The outer wall of the first clamping block 603 is slidably connected to the inner wall of the discharge port 8.

[0042] More specifically, when the thread needs to be cut, during the flipping of the protective cover 13, the outer wall of the protective cover 13 will press the extrusion rod 608, causing the extrusion rod 608 to drive the connecting plate 601 to slide along the side wall of the conveyor box 2. At the same time, the second spring 607 will be compressed. Then, the connecting plate 601 will drive the first connecting rod 602 and the second connecting rod 605 to move synchronously, causing the two first clamping blocks 603 to move towards each other, thereby clamping the outer wall of the thread end to be used. At the same time, the second connecting rod 605 will cause the two second clamping blocks 606 to move towards each other, thereby clamping the outer wall of the thread end to be cut.

[0043] During the subsequent cutting of the suture by the 504 cutting blade, the blade maintains a clamping effect on the suture, ensuring its stability during cutting. This allows for accurate cutting along a predetermined trajectory, avoiding cutting errors caused by suture movement, ensuring cutting accuracy and consistency, and improving the precision of the surgical procedure. It also prevents the suture from swinging arbitrarily during cutting, which could affect the cutting effect.

[0044] After the cutter 504 has finished cutting the suture and reset, the first clamping block 603 maintains its clamping effect on the suture. When the operator needs to remove the suture, the protective cover 13 is flipped to reset it. At this time, the protective cover 13 no longer squeezes the compression rod 608. Then, the elastic force generated by the compression of the second spring 607 drives the two connecting plates 601 to slide away from each other. Only then will the first clamping block 603 release its effect on the suture. The clamping of the suture is controlled by opening and closing the protective cover 13. When the protective cover 13 is open, the cut suture cannot be removed. Only when the protective cover 13 is closed can the cut suture be removed, thus preventing the situation of forgetting to put the cover back on.

[0045] Example 4, please refer to Figure 1 and Figure 7 Based on Embodiment 3, in this embodiment, the end of the moving plate 4 away from the card block 508 is fixedly connected to the limiting block 11, and the side wall of the limiting block 11 is provided with a limiting groove 12, and the outer wall of the second connecting rod 605 is slidably connected to the inner wall of the limiting groove 12.

[0046] More specifically, during the clamping of the thread before cutting, the displacement of the moving plate 4 causes the limiting block 11 to move synchronously. Then, the limiting groove 12 causes the second connecting rod 605 to move, allowing the second connecting rod 605 to slide along the inside of the second sliding groove 10. Since the second clamping block 606 is already holding the thread, the second connecting rod 605 will stretch the thread during the displacement process, thus smoothing the thread. Stretching the thread also helps the cutting process to proceed smoothly. After the cutting is completed, the second connecting rod 605 will move the new end of the thread past the blade of the cutter 504 and into the discharge port 8 during the reset process. This ensures that the thread is automatically transported a certain distance after cutting, preventing the operator from crossing the blade side and directly touching the area where the thread is located, thus avoiding injury to the operator.

[0047] The working principle of this invention is as follows: the take-up box 1 can provide storage for sewing thread. Since the cover plate 15 is detachable, the cover plate 15 is first disassembled, and then the rolled sewing thread is placed inside the take-up box 1. At the same time, the outer end of the sewing thread is passed through the inside of the conveyor box 2 to the inside of the outlet 8. Then the cover plate 15 is reinstalled and fixed to the side wall of the take-up box 1, thereby completing the installation of the sewing thread.

[0048] When sewing thread is needed, first pull the end of the sewing thread inside the outlet 8 outward. The sewing thread will then extend outward. When the sewing thread extending out of the conveyor box 2 reaches the required length, the sewing thread needs to be cut. Manually flip the protective covers 13 located on the upper and lower sides of the conveyor box 2 simultaneously. Then, the buttons 14 inside the protective covers 13 will be exposed. Then, by pressing the two buttons 14 at the same time, the drive motor 7 will be triggered. The output shaft of the motor 7 will drive the bidirectional screw 3 to rotate synchronously. Then, the moving plate 4 will drive the sliding block 506 to move synchronously. At the same time, the sliding block 506 will drive the locking block 508 to move synchronously. At this time, the two cutters 504 will move relative to each other, so that the outer wall of the sewing thread will be squeezed and cut through the blade of the cutter 504. During the process, the first spring 505 will be compressed. Since the cutter 504 is designed to be inclined, the cutter 504 will cut obliquely according to the tilt angle during the cutting process. By cutting obliquely, the cutter 504 can avoid cutting the barb tissue on the sewing thread during the cutting process.

[0049] When the thread needs to be cut, during the flipping of the protective cover 13, the outer wall of the protective cover 13 will press the extrusion rod 608, causing the extrusion rod 608 to drive the connecting plate 601 to slide along the side wall of the conveyor box 2. At the same time, the second spring 607 will be compressed. Then, the connecting plate 601 will drive the first connecting rod 602 and the second connecting rod 605 to move synchronously, causing the two first clamping blocks 603 to move towards each other, thereby clamping the outer wall of the thread end to be used. At the same time, the second connecting rod 605 will cause the two second clamping blocks 606 to move towards each other, thereby clamping the outer wall of the thread end to be cut.

[0050] When the operator needs to remove the suture, the protective cover 13 is flipped to reset. At this time, the protective cover 13 no longer squeezes the compression rod 608. Then, the elastic force generated by the compression of the second spring 607 drives the two connecting plates 601 to slide away from each other. Only then will the first clamping block 603 release its effect on the suture. The clamping of the suture is controlled by opening and closing the protective cover 13. When the protective cover 13 is open, the cut suture cannot be taken out. Only when the protective cover 13 is closed can the cut suture be taken out, thus preventing the situation of forgetting to put the cover back on.

[0051] It should be noted that all the devices in this application are common devices on the market, and can be selected according to the needs of specific use. The circuit connection relationship of each device is a simple series and parallel connection circuit. There is no innovation in the circuit connection part. Those skilled in the art can easily implement it. It belongs to the prior art and will not be described in detail.

[0052] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
