Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a modular component and a modular suture device for fixing drainage tubes, and a method of using them. Background Technology

[0002] In the field of surgery, wound closure and drainage tube placement are crucial procedures for ensuring postoperative recovery. However, existing technologies have many drawbacks, severely impacting surgical efficiency and patient experience:

[0003] 1. Traditional sutures are mostly designed in a single size, which can only be adapted to straight wounds of fixed length. They are difficult to suture precisely for irregular wounds or wounds of different depths or widths. Multiple types of sutures need to be prepared, which increases surgical preparation time and medical costs. Frequent changes of instruments can prolong the operation time and increase the risk of infection.

[0004] 2. In traditional surgery, after the wound is sutured, the drainage tube needs to be attached to the patient's skin with tape. The tape can easily cause skin allergies and itching, and it is not secure, so the drainage tube is easy to shift or fall off, affecting the drainage effect. In addition, the tape can pull on the wound when it is changed, which can aggravate the patient's discomfort. This is not in line with the development trend of minimally invasive and comfortable medical care.

[0005] 3. The existing suture device has an imperfect design for limiting and driving the suture needle. During the suturing process, the suture needle is prone to lateral deviation or longitudinal movement, resulting in uneven suture spacing and loose wound closure. Some patients need to be sutured twice, which increases pain and recovery time. At the same time, the suture needle pushing mechanism is prone to jamming, affecting the continuity of the operation. Summary of the Invention

[0006] This invention discloses a modular component and a modular suture device for fixing drainage tubes, as well as a method of use. It aims to achieve coordinated operation of different wound adaptation, stable suturing, integrated installation of drainage tubes, and surgical lighting through a simplified and efficient structural design. The core technical solution is as follows.

[0007] A modular component, comprising:

[0008] The mounting base and the main body are provided with multiple sliding grooves on both sides of the mounting base. Sliding plates are fixedly connected to both sides of the bottom of the main body. A mounting groove is formed between two sliding plates, and the mounting base is located in the mounting groove. A sliding rail is provided on the side of the two sliding plates that are close to each other, and the sliding rail is slidably connected to the sliding groove.

[0009] It also includes a handle fixedly connected to the bottom of the main body, and the handle is located on one side of the mounting base and abuts against the mounting base for limiting the mounting base. Two base plates are fixedly connected to one side of the main body, and the two base plates are rotatably connected to the same rotating shaft. A limiting block is fixedly sleeved on the outer wall of the rotating shaft, and the limiting block cooperates with the handle to clamp and fix the mounting base.

[0010] The mounting base is positioned by sliding the sliding plate and the mounting base, and the limit block and the handle cooperate to enable quick clamping and replacement of the mounting base.

[0011] In one possible design, a light is fixedly connected to the bottom of the limiting block to provide illumination for the doctor, and a rubber ring is fixedly embedded on the side of the handle near the mounting base, and the rubber ring cooperates with the limiting block to increase the stability of clamping the mounting base.

[0012] A modular suture device for fixing a drainage tube, comprising the aforementioned modular component, and further comprising:

[0013] A flip cover plate is rotatably connected inside the mounting base. A support plate I is fixedly connected to the inner wall of the mounting base near the handle. Multiple suture needles are placed on the support plate I. A hollow ring is fixedly connected to the top of each suture needle to facilitate the installation of a drainage tube after the wound is sutured.

[0014] A suture structure for suturing wounds by bending a suture needle. The suture structure includes two pressure blocks slidably connected to the inner wall of the mounting base on the side away from the handle, and a baffle fixedly connected to the inner wall of the mounting base on the side away from the handle. The baffle is located between the two pressure blocks and is used to limit the movement of the suture needle.

[0015] A conveying structure is used to automatically convey suture needles after the suturing operation is completed. The conveying structure includes a pusher seat slidably connected to the top of the support plate I, and the pusher seat is used to push multiple suture needles to move towards the baffle.

[0016] The drive mechanism, located inside the handle, is used to drive the sewing structure.

[0017] In one possible design, the stitching structure further includes a T-shaped plate slidably connected within the mounting base, and the T-shaped plate is slidably connected to the top of the support plate I. Push plates are fixedly connected to both sides of the T-shaped plate. The two push plates are slidably connected to the inner wall of the mounting base on opposite sides. A connecting rod is rotatably connected to the side of the two push plates away from the T-shaped plate. A rotating pin is fixedly connected to the side of the two pressure blocks away from each other. One end of the rotating pin is vertically slidably connected to the inner wall of one side of the mounting base. One end of the connecting rod is rotatably sleeved on the outer wall of the corresponding rotating pin, and is used to drive the pressure block to move up and down through the connecting rod when the push plate moves.

[0018] Multiple support plates II slide through the baffle to support the suture needle that is against the baffle. The ends of the multiple support plates II away from the suture needle are all fixedly connected to springs I through spring seats, and one end of spring I is fixedly connected to the inner wall of the mounting base through spring seats. The top of the multiple support plates II is provided with a sloping groove. A pressure rod is fixedly connected between the two pressure blocks, and the pressure rod cooperates with the sloping groove to drive the support plate II to squeeze the spring I to release the support of the suture needle.

[0019] The T-shaped plate drives the pressure block to move downward through the rotation of the push plate and the connecting rod. The pressure block presses down on the suture needle, causing it to bend and suture the wound. During the pressing, the support plate II limits the suture needle. After the suture needle is bent, the pressure rod extends into the inclined groove and drives the support plate II to move away from the baffle, releasing the limitation on the suture needle.

[0020] In one possible design, the drive structure includes two bases fixedly connected to the inner wall of the top of the handle. The two bases are rotatably connected to the same shaft. Two cams are fixedly sleeved on the outer wall of the shaft. Two torsion springs are sleeved on the outer wall of the shaft. The two ends of the two torsion springs are fixedly connected to the corresponding cams and bases respectively through spring seats. A lever located between the two cams is fixedly sleeved on the outer wall of the shaft. A U-shaped plate that cooperates with the cams is slidably connected to the inner wall of the top of the handle. Two push rods are fixedly connected to the side of the U-shaped plate away from the lever. One end of each push rod slides into the mounting base and cooperates with a T-shaped plate. A magnet III is fixedly embedded on the side of the T-shaped plate near the push rod. A third sheet metal layer is fixedly connected to one end of the push rod, and a magnetic attraction force is generated between the third sheet metal layer and the magnet III. This magnetic attraction force is used to synchronously drive the T-shaped plate to move when the push rod is reset. A spring II is sleeved on the outer wall of the push rod. The two ends of the spring II are fixedly connected to the U-shaped plate and the handle respectively through spring seats.

[0021] In this system, pressing the lever with your finger drives the cam to rotate counterclockwise via a rotating shaft. The cam then pushes the push rod and T-shaped plate to move via a U-shaped plate, thereby driving the stitching structure to operate.

[0022] In one possible design, the conveying structure further includes two fixed lugs fixedly connected to the bottom of the flip cover plate. Each of the two fixed lugs is fixedly connected to a tension spring through a spring seat. The tension spring is made of medical-grade stainless steel and the elasticity error is controlled within ±5%. One end of each of the two tension springs is fixedly connected to a push seat through a spring seat to provide driving force for the push seat to push the suture needle to move.

[0023] The pusher seat has a top plate that slides through it, and the top plate cooperates with the support plate I to limit the suture needle in the vertical direction. A magnet II is fixedly embedded in the pusher seat. A first sheet metal layer is fixedly connected to the top of the top plate, and a magnetic attraction is generated between the magnet II and the first sheet metal layer to make the pusher seat drive the top plate to move. Two magnets I are fixedly embedded on the side of the top plate near the pressure block. A second sheet metal layer is fixedly embedded on one side of each of the two pressure blocks, and a magnetic attraction is generated between the magnet I and the second sheet metal layer to ensure the stability of the top plate.

[0024] When the suture needle at the end is removed from the mounting base, the tension of the spring on the push base pushes the remaining suture needles toward the baffle.

[0025] In one possible design, a limiting plate I is fixedly connected to the bottom of the push seat, and a limiting plate II is fixedly connected inside the mounting seat. The limiting plate II cooperates with the limiting plate I to limit the suture needle and prevent the suture needle from tilting. Multiple limiting plates III are fixedly connected to one inner wall of the mounting seat to limit the flip cover. The mounting seat has a notch on the side away from the handle to facilitate suturing the wound with the suture needle.

[0026] In one possible design, the suture needle is U-shaped, and the top plate has a clearance groove for making way for the hollow ring.

[0027] In one possible design, one end of the rotating shaft is provided with a groove, and an internal gear ring is fixedly connected in the groove. A fixed post slides through one of the base plates, and one end of the fixed post extends into the groove and is fixedly connected to a gear, which meshes with the internal gear ring to limit the rotation shaft. A spring III is sleeved on the outer wall of the fixed post. One end of the spring III is fixedly connected to an adjacent base plate through a spring seat, and the other end of the spring III is fixedly connected to the outer wall of the fixed post through a spring seat. A limiting ring is fixedly connected in the groove, and the limiting ring is located between the gear and the spring III to limit the gear.

[0028] The internal gear ring and the gear mesh to position the limit block, which in turn engages with the handle to clamp the mounting seat. When the gear disengages from the internal gear ring, it can drive the rotating shaft and the limit block to rotate to replace the mounting seat.

[0029] This application discloses a method for using a modular suture device for fixing a drainage tube, comprising the following steps:

[0030] S1. Select the appropriate suture staples for suturing according to the patient's wound. Specifically, push the fixing post and gear towards the rotating shaft. Spring III is compressed, and the gear disengages from the internal gear ring. At this time, the limiting block can be rotated to release the limitation on the mounting seat. The mounting seat can be removed and replaced. The replaced mounting seat can use suture staples for the wound. The two sliding plates can limit the mounting seat. Then, rotate the limiting block in the opposite direction to limit the mounting seat and release the push on the fixing post. The gear resets under the elastic force of spring III, and the gear re-engages with the internal gear ring, limiting the rotating shaft and the limiting block, thus completing the fixation of the mounting seat. In addition, the rubber ring and the limiting block can fully clamp the mounting seat, increasing the stability of the mounting seat installation.

[0031] S2. When suturing the wound, the patient's wound is closed with forceps, the notch is aligned with the wound, and the finger presses the lever. The lever drives the cam to rotate counterclockwise through the shaft. The cam pushes the push rod and T-shaped plate to move through the U-shaped plate. The T-shaped plate drives the pressure block to move down through the rotation of the push plate and the connecting rod. The pressure block can press the suture needle and bend the suture needle to suture the wound. When pressing, the support plate II limits the suture needle to prevent the pressure block from pushing the suture needle down. After the suture needle is bent, the pressure rod between the two pressure blocks extends into the inclined groove and drives the support plate II to move away from the baffle with the cooperation of the inclined groove, releasing the limitation on the suture needle and making it easier to remove the mounting seat from the wound later.

[0032] S3. When the pressure on the lever is released, the U-shaped plate and the push rod are reset under the action of spring II. The push rod drives the push plate to reset through the attraction between magnet III and T-shaped plate. The push plate simultaneously drives the pressure block to move upward and reset, while the support plate II is reset under the action of spring I.

[0033] S4. When the suture needle at the end is removed from the mounting base, the tension spring pulls on the push seat, pushing the remaining suture needles towards the limiting plate II, thus facilitating subsequent suturing. The support plate I supports the multiple suture needles, and the cooperation between the limiting plate I and the limiting plate II can prevent the suture needles from tilting. After the multiple suture needles have completed the wound suturing, the drainage tube can be passed through the multiple hollow rings to complete the installation of the drainage tube, which is convenient to use. In addition, the lighting lamp installed at the bottom of the limiting block can provide lighting for the doctor, making it convenient for the doctor to perform suturing surgery.

[0034] Beneficial effects: In this invention, the sliding plate and the mounting base can limit the mounting base through sliding cooperation, and the limiting block and the handle can clamp and fix the mounting base. The mounting base can be replaced as needed (modular quick replacement design) to adapt to the suturing of different wounds of patients.

[0035] In this invention, the T-shaped plate drives the pressure block to move downward through the rotation of the push plate and the connecting rod. The pressure block can press the suture needle and bend it to suture the wound. When pressing, the support plate II limits the suture needle to prevent the pressure block from pushing the suture needle downward. After the suture needle is bent, the pressure rod between the two pressure blocks extends into the inclined groove and drives the support plate II to move away from the baffle with the cooperation of the inclined groove, releasing the limitation on the suture needle and making it easier to remove the mounting seat from the wound later.

[0036] In this invention, the suture needle is U-shaped, and a hollow ring is welded to the top of the suture needle to facilitate the subsequent installation of the drainage tube (integrated installation of the drainage tube). The top plate is provided with a clearance groove to allow the hollow ring to make way.

[0037] In this invention, when the suture needle at the end is removed from the mounting base, the tension of the spring on the push base pushes the remaining multiple suture needles toward the limiting plate II, thereby facilitating subsequent suturing. The limiting plate II cooperates with the limiting plate I to limit the suture needle and prevent the suture needle from tilting.

[0038] In this invention, the sliding fit and clamping structure allow for the replacement of the mounting base as needed to adapt to different wound suturing techniques; the T-shaped plate and other components work together to ensure stable suturing by the suture needle and prevent deviation; the U-shaped suture needle and hollow ring design facilitate the installation of drainage tubes; the delivery structure automatically pushes the suture needle, improving efficiency; and the bottom lighting of the limiting block provides convenience for the operation, thus improving the reliability and convenience of the suturing operation as a whole.

[0053] 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.

[0054] In one embodiment: Refer to Figure 1 and Figure 13 A modular component, relating to the field of medical device technology, mainly includes a mounting base 1 and a main body 28. The mounting base 1 is cuboid in shape, with multiple sliding grooves on both sides. Sliding plates 32 are fixed to both sides of the bottom of the main body 28. The sliding plates 32 are made of high-strength plastic, and a mounting groove is formed between two sliding plates 32, allowing the mounting base 1 to be stably positioned within the mounting groove. Two slide rails are provided on the side of the two sliding plates 32 that are close to each other. The slide rails slide in conjunction with the sliding grooves, with the coefficient of sliding friction controlled between 0.1 and 0.2, ensuring that the main body 28 can slide smoothly on the mounting base 1.

[0055] Reference Figure 1 The bottom of the main body 28 is also fixed with a handle 33. The handle 33 is ergonomically designed and has an anti-slip texture on its surface. The handle 33 is located on one side of the mounting base 1 and abuts against the mounting base 1 to limit the mounting base 1.

[0056] Reference Figure 1 Two base plates 29 are fixed on one side of the main body 28. The base plates 29 are made of metal. The two base plates 29 are rotatably connected by the same rotating shaft 30. A limiting block 31 is fixedly sleeved on the outer wall of the rotating shaft 30. The limiting block 31 is made of hard plastic and its size is designed according to the actual clamping requirements. It cooperates with the handle 33 to clamp and fix the mounting base 1.

[0057] Reference Figure 1 The bottom of the limiting block 31 is fixed with a light 42. The light 42 uses an LED light source and the brightness is adjustable, which can provide clear lighting for doctors and meet the needs of different surgical scenarios. A rubber ring 49 is fixedly embedded on the side of the handle 33 near the mounting base 1. The rubber ring 49 has a hardness of 40-60 Shore A and a thickness of 2-4mm. The rubber ring 49 and the limiting block 31 can increase the stability of the mounting base 1 and prevent the mounting base 1 from shaking during the operation.

[0058] Reference Figure 2 and Figure 3 A modular suture device for fixing a drainage tube includes the aforementioned modular component and a flip cover 2 rotatably connected within a mounting base 1. The flip cover 2 is made of lightweight plastic and is rotatably connected to the mounting base 1 via a hinge, allowing for easy opening and closing.

[0059] Reference Figure 2 , Figure 3 and Figure 5 A support plate I3 is fixed to the inner wall of the mounting base 1 near the handle 33. The support plate I3 is made of metal and has a thickness of 2-4 mm. Multiple suture needles 4 are placed on the support plate I3. The suture needles 4 are U-shaped, made of stainless steel, and have a diameter of 0.5-1 mm. The length is designed according to the actual surgical needs. A hollow ring 5 with a diameter of 2-4 mm is fixed to the top of the suture needle 4 to facilitate the installation of drainage tubes after suturing recurrent wounds.

[0060] Reference Figure 2 , Figure 4 and Figure 7 The suture structure is used to bend the suture needle 4 for wound suturing. It mainly includes two pressure blocks 18 that slide on the inner wall of the mounting base 1 away from the handle 33, and a baffle 21 that is fixed to the inner wall of the mounting base 1 away from the handle 33. The baffle 21 is made of metal and is 3-5mm thick. It is located between the two pressure blocks 18 and is used to limit the movement of the suture needle 4.

[0061] Reference Figure 2 , Figure 4 and Figure 7 The stitching structure also includes a T-shaped plate 15 sliding within the mounting base 1. The T-shaped plate 15 is made of metal and is located on top of the support plate I3. Push plates 14, also made of metal, are fixed to both sides of the T-shaped plate 15. The two push plates 14 slide on the inner wall of the mounting base 1 on opposite sides. A connecting rod 17, made of metal and with a diameter of 3-5 mm, is rotatably connected to the side of each push plate 14 away from the T-shaped plate 15. Rotating pins 19, also made of metal, are fixed to the opposite sides of each pressure block 18. One end of each rotating pin 19 is vertically slidably connected to the inner wall of one side of the mounting base 1. One end of each connecting rod 17 is rotatably sleeved on the outer wall of the corresponding rotating pin 19, used to drive the pressure block 18 to move up and down via the connecting rod 17 when the push plate 14 moves.

[0062] Reference Figure 2 , Figure 4 , Figure 7 and Figure 8Multiple support plates II 22 slide through the baffle 21 to support the suture needle 4 that is attached to the baffle 21. Each support plate II 22 has a spring I 23 fixed to its end away from the suture needle 4 via a spring seat. The spring I 23 is made of stainless steel with a wire diameter of 0.5-0.8 mm, a mean diameter of 4-6 mm, a free length of 8-12 mm, and a spring constant between 3-6 N / mm. One end of the spring I 23 is fixedly connected to the inner wall of the mounting base 1 via the spring seat. Each support plate II 22 has a sloping groove 24 at its top, with an inclination angle of 30°-45°. A pressure rod 20 is fixed between two pressure blocks 18, and the pressure rod 20 cooperates with the sloping groove 24 to drive the support plate II 22 to compress the spring I 23 and release the support for the suture needle 4.

[0063] During operation, the T-shaped plate 15 drives the pressure block 18 downward through the rotational cooperation of the push plate 14 and the connecting rod 17. The pressure block 18 can press the suture needle 4 and bend it to suture the wound. When pressing, the support plate II 22 limits the suture needle 4 to prevent the pressure block 18 from pushing the suture needle 4 downward. After the suture needle 4 is bent, the pressure rod 20 between the two pressure blocks 18 extends into the inclined groove 24 and drives the support plate II 22 to move away from the baffle 21 with the cooperation of the inclined groove 24, releasing the limitation on the suture needle 4 and making it easier to remove the mounting base 1 from the wound later.

[0064] Reference Figures 3-6 The conveying structure is used to automatically convey the suture needles 4 after the suturing operation is completed. It mainly includes a pusher seat 6 sliding on the top of the support plate I3, used to push multiple suture needles 4 towards the baffle 21. The conveying structure also includes two fixing lugs 8 fixed to the bottom of the flip cover plate 2. The fixing lugs 8 are made of metal and have a thickness of 3-5mm. Each of the two fixing lugs 8 has a tension spring 9 fixed inside it via a spring seat. The tension spring 9 is made of stainless steel, with a wire diameter of 0.6-1mm, a median diameter of 5-8mm, a free length of 10-15mm, and a spring constant between 4-7N / mm. One end of each tension spring 9 is fixedly connected to the pusher seat 6 via a spring seat, providing driving force for the pusher seat 6 to move the suture needles 4. A top plate 10 slides through the pusher seat 6. The top plate 10 is made of plastic and has a thickness of 2-4mm. The top plate 10 cooperates with the support plate I3 to limit the suture needles 4 in the vertical direction. A magnet II13 is fixedly embedded in the push base 6, and a first iron sheet layer is fixed on the top of the top plate 10. The magnet II13 and the iron sheet layer generate magnetic attraction force, which is used to make the push base 6 drive the top plate 10 to move.

[0065] Reference Figure 5 and Figure 7Two magnets I11 are fixedly embedded on the side of the top plate 10 near the pressure block 18. A second iron sheet layer is fixedly embedded on one side of each of the two pressure blocks 18, and the magnets I11 and the second iron sheet layer generate magnetic attraction to ensure the stability of the top plate 10. When the suture needle 4 at the end is removed from the mounting base 1, the tension spring 9 pulls on the push base 6 to push the remaining suture needles 4 toward the limiting plate II25, thereby facilitating subsequent suturing. The surfaces of magnets I11 and magnets II13 are coated with anti-corrosion coatings to prevent body fluids from affecting the adsorption effect.

[0066] Reference Figures 2-7 A limiting plate I7 ​​is fixed to the bottom of the push seat 6. A limiting plate II25 is fixed inside the mounting seat 1. The limiting plate II25 cooperates with the limiting plate I7 ​​to limit the suture needle 4 and prevent the suture needle 4 from tilting. Multiple limiting plates III27 are fixed to one inner wall of the mounting seat 1. The limiting plates III27 are made of metal and are 2-4mm thick, and are used to limit the flip cover 2. A notch 26 is provided on the side of the mounting seat 1 away from the handle 33 to facilitate suturing the wound through the suture needle 4. An avoidance groove 12 is provided in the top plate 10 to allow the hollow ring 5 to pass.

[0067] Reference Figure 9 and Figure 10 To facilitate the operation of the suture structure by the doctor, a drive mechanism is provided within the handle 33. The drive mechanism includes two bases 34, made of metal, fixed to the inner top wall of the handle 33. A common rotating shaft 35 rotatably connects the two bases 34. Two cams 37, also made of metal, are fixedly fitted onto the outer wall of the rotating shaft 35, their contours designed according to the drive requirements. Two torsion springs 38, made of stainless steel, are fitted onto the outer wall of the rotating shaft 35. These springs have a wire diameter of 0.5-0.8 mm, a median diameter of 4-6 mm, a free length of 8-12 mm, and a spring constant between 2-5 N / mm. The two ends of the two torsion springs 38 are fixedly connected to the corresponding cams 37 and bases 34 via spring seats. A lever 36, located between the two cams 37, is fixedly fitted onto the outer wall of the rotating shaft 35. A U-shaped plate 39, made of metal and designed to mate with the cams 37, is slidably connected to the inner top wall of the handle 33. The outer wall of the push rod 40 is fitted with a spring II 41, and the two ends of the spring II 41 are fixedly connected to the U-shaped plate 39 and the handle 33 respectively through spring seats.

[0068] Reference Figure 7 , Figure 9 and Figure 10Two push rods 40 are fixed on the side of the U-shaped plate away from the lever 36. One end of each push rod 40 slides into the mounting base 1 and engages with the T-shaped plate 15. A magnet III 16 is fixedly embedded on the side of the T-shaped plate 15 near the push rod 40. A third sheet metal layer is fixed to one end of the push rod 40, and a magnetic attraction is generated between the third sheet metal layer and the magnet III 16, which is used to synchronously drive the T-shaped plate 15 to move when the push rod 40 is reset.

[0069] When in use, pressing the lever 36 with a finger causes the lever 36 to drive the cam 37 to rotate counterclockwise via the rotating shaft 35. The cam 37 then pushes the push rod 40 and the T-shaped plate 15 to move via the U-shaped plate 39, thereby driving the stitching structure to operate.

[0070] In another embodiment: Refer to Figure 4 , Figure 11 and Figure 12 A groove 43 is provided at one end of the rotating shaft 30, and an internal gear ring 44 is fixed in the groove 43. A fixed post 45 slides through a base plate 29. One end of the fixed post 45 extends into the groove 43 and is fixed with a gear 47. The gear 47 meshes with the internal gear ring 44 to limit the rotation of the rotating shaft 30. A spring III 48 is sleeved on the outer wall of the fixed post 45. The spring III 48 is made of stainless steel with a wire diameter of 0.8-1.2 mm, a mean diameter of 6-10 mm, a free length of 15-20 mm, and a spring constant between 5-10 N / mm. One end of the spring III 48 is fixedly connected to the adjacent base plate 29 through a spring seat, and the other end is fixedly connected to the outer wall of the fixed post 45 through a spring seat. A limiting ring 46 is fixed in the groove 43, located between the gear 47 and the spring III 48, to limit the gear 47. The engagement of the internal gear ring 44 and the gear 47 can position the limiting block 31, thereby enabling the limiting block 31 to cooperate with the handle 33 to clamp the mounting base 1. Conversely, the engagement of the gear 47 and the internal gear ring 44 can drive the rotating shaft 30 and the limiting block 31 to rotate, which is used to replace the mounting base 1.

[0071] A method for using a modular suture device for fixing a drainage tube includes the following steps:

[0072] S1. Select the appropriate suture staples according to the patient's wound for suturing. Specifically, push the fixing post 45 and gear 47 to move towards the rotating shaft 30. The spring III 48 is compressed, and the gear 47 disengages from the internal gear ring 44. At this time, the limiting block 31 can be rotated to release the limitation on the mounting seat 1. The mounting seat 1 can be taken out for replacement. The replaced mounting seat 1 can use suture staples for the wound. The two sliding plates 32 can limit the mounting seat 1. Then, rotate the limiting block 31 in the opposite direction to limit the mounting seat 1 and release the push on the fixing post 45. The gear 47 resets under the elastic force of the spring III 48. The gear 47 re-engages with the internal gear ring 44 and limits the rotating shaft 30 and the limiting block 31, thus completing the fixation of the mounting seat 1. In addition, the rubber ring 49 and the limiting block 31 can fully clamp the mounting seat 1, increasing the stability of the mounting seat 1 installation.

[0073] S2. When suturing the wound, the patient's wound is closed with forceps, and the notch 26 is placed against the wound. The finger presses the lever 36, and the lever 36 drives the cam 37 to rotate counterclockwise through the rotating shaft 35. The cam 37 pushes the push rod 40 and the T-shaped plate 15 to move through the U-shaped plate 39. The T-shaped plate 15 drives the pressure block 18 to move down through the rotation of the push plate 14 and the connecting rod 17. The pressure block 18 can press the suture needle 4 and bend the suture needle 4 to suture the wound. When pressing, the support plate II 22 limits the suture needle 4 to prevent the pressure block 18 from pushing the suture needle 4 down. After the suture needle 4 is bent, the pressure rod 20 between the two pressure blocks 18 extends into the inclined groove 24 and drives the support plate II 22 to move away from the baffle 21 with the cooperation of the inclined groove 24, releasing the limitation on the suture needle 4, so that the mounting base 1 can be removed from the wound later.

[0074] S3. When the pressure on the lever 36 is released, the U-shaped plate 39 and the push rod 40 are reset under the action of the spring II 41. The push rod 40 drives the push plate 14 to reset through the attraction between the magnet III 16 and the T-shaped plate 15. The push plate 14 simultaneously drives the pressure block 18 to move upward and reset, while the support plate II 22 is reset under the action of the spring I 23.

[0075] S4. When the suture needle 4 at the end is removed from the mounting base 1, the tension spring 9 pulls on the push base 6 to push the remaining multiple suture needles 4 towards the limiting plate II 25, which facilitates subsequent suturing. The support plate I 3 supports the multiple suture needles 4, and the cooperation between the limiting plate I 7 and the limiting plate II 25 can prevent the suture needles 4 from tilting. After the multiple suture needles 4 have completed the wound suturing, the drainage tube can be passed through the multiple hollow rings 5 ​​to complete the installation of the drainage tube, which is convenient to use. In addition, the lighting lamp 42 installed at the bottom of the limiting block 31 can provide lighting for the doctor, which is convenient for the doctor to perform suturing surgery.

[0076] However, as is well known to those skilled in the art, the working principle and wiring method of the lighting lamp 42 are conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selection according to their needs or convenience.

[0077] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0078] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
