Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more particularly to a suture device for cesarean section incisions. Background Technology

[0002] Cesarean section is an obstetric medical procedure that delivers the fetus through an abdominal surgical incision. It is mainly used in emergency situations such as dystocia and pregnancy complications. The incision needs to be sutured during the operation.

[0003] Currently, the incision for cesarean section is located in the lower abdomen of the patient. It requires cutting multiple layers of subcutaneous muscle simultaneously. When suturing the incision, manual suturing is mostly used. The muscle incisions at different depths are gradually sutured using suture needles and sutures. The suture site of the muscle incision will experience long-term and intermittent nerve throbbing pain.

[0004] Because new mothers are physically weak after childbirth, in order to avoid the damage to their bodies caused by prolonged use of painkillers and pain medications, most existing pain relief methods simply involve applying anesthetic to the wound with a cotton swab. However, this method can only relieve pain at the surface of the incision, and the anesthetic cannot penetrate into the inner layers of the incision. Nerve throbbing pain will still occur at the suture site of the inner incision. Summary of the Invention

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1-13 The present invention provides a technical solution: a suture device for cesarean section incision, comprising two upright plates 1 and multiple needle seats 10, the multiple needle seats 10 being arranged in two rows to form a needle row, wherein two opposite needle seats 10 are a group, each of the multiple needle seats 10 having an annular plate 25 at its bottom, each of the multiple annular plates 25 having a needle rod 9 fixed at its bottom, each of the multiple needle rods 9 being hollow inside and extending through to the top of the annular plate 25, each of the multiple needle rods 9 having a bridging component inside, each of the multiple needle seats 10 having a drainage component inside, the outer surface of the needle rod 9 being embedded with a permeation sheath 13, and a pushing device being slidably disposed between opposite sides of the two upright plates 1;

[0036] Multiple slots 3 are equidistantly provided between the opposite sides of the two upright plates 1 near the top edge. A support plate 2 is provided between each of the two opposite slots 3. Multiple U-shaped brackets 8 are fixed to the bottom of the two upright plates 1. A side opening 15 is provided at the top of the needle holder 10 near one side edge. An upper opening 14 is provided at the top of the needle holder 10 near the other side edge. A double-headed adhesive 12 is provided inside the side opening 15.

[0037] The effect achieved is as follows: the needle hubs 10 are arranged in two rows to form a needle row, and then the needle row is inserted into the pushing device, so that the top of the needle hub 10 slides and fits into the inner sliding opening 42, and the needle rod 9 is constrained inside the U-shaped frame 8, so that the needle row can be stabilized between the inner sides of the two upright plates 1. Then the needle row is placed on both sides of the incision to be sutured, and then the pushing device is driven by quickly pulling the nylon band 7 to insert the needle rod 9 under the patient's skin. Then, one end of the double-ended adhesive 12 is attached to the skin, and the other end is attached to the side opening 15, so that the needle hub 10 can be fixed and limited. When the patient has nerve throbbing pain in the deep incision, it is only necessary to open one of the sealing bolts 20 and inject the anesthetic into the inner flow channel 18 with a syringe. At this time, the anesthetic can flow to each inner nail rod 17 through the bridging component and the drainage component, and then flow into the strip flow channel 27 through the throttling hole 28, and finally flow out from the permeation sheath 13 to the deep muscle incision site for targeted anesthesia.

[0038] like Figure 1 , Figure 2 , Figure 8 , Figure 9 , Figure 10 and Figure 13As shown, the pushing device includes a pushing block 6. Slides 4 are provided on opposite sides of the two upright plates 1. The pushing block 6 is positioned between opposite sides of the two upright plates 1. A sliding plate 5 is fixed to the top of the pushing block 6 near one edge. Both ends of the sliding plate 5 are slidably engaged inside the slides 4. A nylon strap 7 is fixed to one side of the sliding plate 5. Limiting grooves 41 are provided at the bottom of the pushing block 6 near both sides. The ends of the two limiting grooves 41 near the arc surface of the pushing block 6 are recessed upwards and inclined. The other ends of the two limiting grooves 41 are horizontal. An inner sliding opening 42 is provided on the inner bottom surface of the two limiting grooves 41. A lever 40 is fixed to one side of the inner wall of the two inner sliding openings 42. One end of the two levers 40 is inclined and located away from the arc surface of the pushing block 6.

[0039] The effect achieved is as follows: the support plate 2 supports the two upright plates 1, facilitating subsequent manual hand-held pressure and preventing deformation. The needle holders 10, forming a needle row, are arranged sequentially inside the upright plates 1, and the needle bar 9 is constrained by the U-shaped frame 8, ensuring the needle row is stable between the two upright plates 1. Then, the two upright plates 1 are held and positioned at the incision to be sutured. At this point, the bottom of the needle bar 9 is brought into contact with the patient's skin. After stabilizing the upright plates 1 and the needle row, the nylon band 7 is quickly pulled, causing the pushing block 6 to slide from one end of the upright plate 1 to the other. During the sliding process, the top of the needle holder 10 slides and engages in the inner sliding opening 42. The inner walls of the inner sliding opening 42 are respectively in contact with the inner walls of the side opening 15 and the upper opening 14, allowing for the needle holder 10 to be pressed. The limiter prevents the needle seat 10 from rotating, allowing it to be inserted into the patient's skin and muscle under the action of the inclined surface inside the limiter groove 41. During the sliding process of the needle seat 10 in the inner sliding port 42, the bridging component is triggered by the lever 40, which connects the channel on the inner nail rod 17 with the channel on the needle rod 9. After the needle rod 9 is inserted into the muscle layer, the upright plate 1 is removed, and then the needle seat 10 is attached to the patient's skin by the double-ended adhesive 12. Furthermore, by pulling one end of the traction band 33, the positions of the needle seats 10 on both sides of the incision can be changed, thereby causing the incision to converge towards the middle, which helps to close the incision. When pulling the traction band 33, the first spring plate 35 and the bayonet 34 mutually restrain each other, which can limit the traction band 33 and prevent it from sliding in the opposite direction, causing the incision to open after losing restraint.

[0040] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 12As shown, the bridging assembly includes an inner pin 17. A fitting opening 29 is provided on one side of the top of the inner pin 17. The top of the inner pin 17 is slidably disposed between the inner walls of the needle holder 10. The bottom of the inner pin 17 slidably extends into the interior of the needle bar 9, and the outer surface of the inner pin 17 is slidably and sealingly fitted with the inner wall of the needle bar 9. An inner flow channel 18 extending through to the top is provided inside the inner pin 17. A threaded hole communicating with the inner flow channel 18 is provided at the top of the inner pin 17, and a sealing bolt 20 is threaded into the threaded hole. Side interfaces 19 extending through to the interior of the inner flow channel 18 are provided on both outer surfaces of the inner pin 17. Both side interfaces 19 are aligned with and communicate with the bridging holes 21 on the inner wall of the needle holder 10. The outer surface of the inner pin 17 extends slidably to the top of the annular plate 25 below the side interfaces 19. The outer surface of the inner pin 17 near the bottom... An arc-shaped ring 30 is fixed at the edge of the needle rod 9. Multiple nozzles 31 are equidistantly arranged on the outer surface of the arc-shaped ring 30 along the circumferential direction. All nozzles 31 penetrate into the inner flow channel 18. An annular cavity 26 is formed between the inner walls of the needle rod 9 near the bottom edge. The arc-shaped ring 30 is slidably sealed and engaged in the annular cavity 26. Multiple throttling holes 28 are equidistantly arranged on the inner wall of the annular cavity 26 along the circumferential direction. Multiple strip-shaped flow channels 27 are formed on the outer surface of the needle rod 9. One end of each of the multiple throttling holes 28 penetrates into the interior of the strip-shaped flow channel 27. The permeation sheath 13 is located outside the multiple strip-shaped flow channels 27. A side cavity 37 is formed on one side of the inner wall of the needle seat 10. A reverse tooth plate 38 is fixed inside the side cavity 37. A second spring plate 39 is fixed on the outer surface of the inner nail rod 17. One end of the second spring plate 39 slides against the teeth of the reverse tooth plate 38.

[0041] The effect achieved is that one side of the patch 29 and one side of the upper flat opening 14 are not flush in the initial state. When the needle bar 9 is not inserted into the muscle through the constraint of the inner sliding opening 42, the inner wall of the patch 29 at the top of the inner nail bar 17 is inclined to the inner wall of the upper flat opening 14. The side interface 19 is located on one side of the bridging hole 21 and is not connected to the bridging hole 21. The throttling orifice 28 and the spray orifice 31 are misaligned and opposite. When the needle seat 10 slides inside the inner sliding opening 42 to the horizontal part of one end and contacts the lever 40, since the lever 40 slides to the side of the needle seat 10 while the needle seat 10 does not move, the inclined surface of one end of the lever 40 and the patch 29 are connected. The inner walls of needle 9 are in contact with each other. Under the action of the inclined surface, the inner nail rod 17 can be rotated inside the needle rod 9 until the inner side of the fitting 29 is flush with the inner side of the upper flat opening 14. At this time, the side interface 19 and the bridging hole 21 are connected to each other, and the throttling hole 28 and the spray hole 31 are connected to each other. At the same time, when the inner nail rod 17 rotates, it will drive one end of the second spring plate 39 to slide along the teeth of the reverse tooth plate 38, so that one end of the second spring plate 39 is engaged at the bottom of the teeth, which can limit the inner nail rod 17 and prevent it from rotating back. The inner nail rod 17 slides and seals against its inner wall inside the needle rod 9 through the rubber sealing sleeve.

[0042] like Figure 3 , Figure 4 , Figure 5 , Figure 11 and Figure 12 As shown, the drainage assembly includes a semi-hollow spherical cover 23. Spherical grooves 22 are formed inside the needle holder 10 near both side edges. One side of each spherical groove 22 extends to the outside of the needle holder 10, and a bridging hole 21 is formed on the other side of each spherical groove 22. One end of each bridging hole 21 extends into the needle holder 10 and is in contact with the outer surface of the inner nail rod 17. The semi-hollow spherical cover 23 is correspondingly positioned inside the spherical grooves 22. The outer surface of the semi-hollow spherical cover 23 is slidably and sealingly fitted with the inner wall of the spherical groove 22. The opening of the semi-hollow spherical cover 23 faces the bridging hole 21. A connecting pipe 24 is fixedly connected to one side of the outer surface of the semi-hollow spherical cover 23. The connecting pipe 24 extends to the outside of the needle holder 10, and one end of the connecting pipe 24... A silicone tube 11 is connected, and multiple arc-shaped flow channels 36 are equidistantly opened on the inner wall of the silicone tube 11 along the circumferential direction. A traction band 33 is provided between each group of two needle seats 10. One end of the traction band 33 is fixed to one of the needle seats 10. A constraint seat 16 is fixed on the outer surface of the other needle seat 10. An arc-shaped slide 32 is opened on one side of the constraint seat 16. The top of the arc-shaped slide 32 extends to the top of the constraint seat 16. One end of the traction band 33 slides through the inside of the arc-shaped slide 32 and extends to the top of the constraint seat 16. Multiple slots 34 are equidistantly opened on the top of the traction band 33. A first spring plate 35 is fixed on the inner top surface of the arc-shaped slide 32. One end of the first spring plate 35 is correspondingly engaged in the slot 34.

[0043] The desired effect is that when a patient experiences nerve throbbing pain at a deep incision, only the sealing bolt 20 on one of the needle hubs 10 needs to be opened, and anesthetic is injected into the inner flow channel 18 using a syringe. The anesthetic then flows into the spherical groove 22 through the side interface 19 and bridging hole 21, and then into the silicone tubing 11 through the semi-hollow spherical cover 23 and connecting pipe 24 inside the spherical groove 22. From there, it flows into the adjacent needle hub 10. At the bottom of the inner flow channel 18, the anesthetic flows into the strip flow channel 27 through the spray hole 31 and throttling hole 28, and finally exits through the permeation... The sheath 13 flows out to the deep muscle incision site for targeted anesthesia. The needle hubs 10 are connected by a silicone tubing 11. During the patient's movement, the elasticity of the silicone tubing 11 cushions the skin, preventing the needle hubs 10 from being pulled hard during skin tension and relaxation due to the lack of buffer space after being connected by cotton thread. This would cause the needle hubs 10 and needle shaft 9 to fall off. At the same time, an arc-shaped flow channel 36 is opened on the inner wall of the silicone tubing 11 to prevent the inner wall from contracting towards the middle and causing the internal channel to close when the silicone tubing 11 is stretched.

[0044] Working principle: When using this device, the support plate 2 supports the two upright plates 1, facilitating subsequent manual pressing and preventing deformation. The needle holders 10, forming a needle row, are arranged sequentially inside the upright plates 1, and the needle rod 9 is constrained by the U-shaped frame 8, ensuring the needle row is stable between the two upright plates 1. Then, the two upright plates 1 are held and positioned at the incision to be sutured. At this point, the bottom of the needle rod 9 contacts the patient's skin. After stabilizing the upright plates 1 and the needle row, the nylon band 7 is quickly pulled, causing the pushing block 6 to slide from one end of the upright plate 1 to the other. During the sliding process, the top of the needle holder 10 slides and engages in the inner sliding opening 42. The inner walls of the inner sliding opening 42 interact with the inner walls of the side opening 15 and the upper opening 14, respectively. The fitting mechanism limits the needle holder 10, preventing it from rotating. This allows it to be inserted into the patient's skin and muscle under the action of the inclined surface inside the limiting groove 41. As the needle holder 10 slides in the inner sliding opening 42, the inclined surface of one end of the lever 40 fits against the inner wall of the fitting opening 29, causing the inner nail rod 17 to rotate inside the needle rod 9 until the inner side of the fitting opening 29 is flush with the inner side of the upper flat opening 14. At this point, the side interface 19 and the bridging hole 21 are interconnected, and the throttling orifice 28 and the spray hole 31 are interconnected. Simultaneously, the rotation of the inner nail rod 17 causes one end of the second spring plate 39 to slide along the teeth of the reverse tooth plate 38, locking one end of the second spring plate 39 at the bottom of the teeth, thus limiting the inner nail rod 17 and preventing it from rotating. After rotation and reset, the needle bar 9 is inserted into the muscle layer, and the upright plate 1 is removed. Then, the needle hub 10 is attached to the patient's skin using the double-ended adhesive 12. By pulling one end of the traction band 33, the positions of the needle hubs 10 on both sides of the incision can be changed, thereby converging the incision towards the center and aiding in incision closure. When pulling the traction band 33, it is restrained by the first spring plate 35 and the locking clip 34, which limits the traction band 33 and prevents it from sliding backward and causing the incision to open due to loss of restraint. When the patient experiences nerve throbbing pain from a deep incision, it is only necessary to open the sealing bolt 20 on one of the needle hubs 10 and inject anesthetic into the internal flow channel 18 with a syringe. At this time, the anesthetic can flow into the spherical groove 22 through the side interface 19 and the bridging hole 21, and then through the spherical groove. The semi-hollow spherical cover 23 and connecting tube 24 inside the 22 enter the silicone tubing 11, flowing into the adjacent needle hub 10 through the silicone tubing 11. The anesthetic flows into the strip-shaped flow channel 27 at the bottom of the inner flow channel 18 through the spray hole 31 and the throttling hole 28, and finally flows out from the permeation sheath 13 to the deep muscle incision site for targeted anesthesia. The various needle hubs 10 are connected by the silicone tubing 11. During the patient's movement, as the skin relaxes and contracts, the elasticity of the silicone tubing 11 provides cushioning, preventing the needle hubs 10 from being pulled hard during skin relaxation due to insufficient cushioning after being connected by cotton thread, thus preventing the needle hubs 10 from detaching along with the needle shaft 9. At the same time, an arc-shaped flow channel 36 is opened on the inner wall of the silicone tubing 11 to prevent the silicone tubing 11 from being stretched when pulled.The inner wall contracts towards the center, causing the internal passage to close.
