Description

Technical Field

[0001] This utility model relates to the field of suture technology, and in particular to a suture that facilitates adjustment of suture force. Background Technology

[0002] Skin suture devices are disposable, manually operated skin suturing instruments suitable for suturing skin incisions in general surgery, chest surgery, abdominal surgery, and burn surgery, including skin grafting. A skin suture device is a device that attaches the suture to both sides of the skin, then tightens the clips to perfectly align the edges of the incision. The advantages are that there are no sutures at the incision site, the incision is perfectly aligned, and the postoperative scar is lighter. It is suitable for relatively short, uninfected, and neat wounds.

[0003] Existing skin suture devices involve attaching two pieces of adhesive tape to the skin on both sides of the wound, then tightening the straps to close the wound together. Because the suture device needs to be very small and fit snugly against the patient's skin, adjusting the length of the lever is very inconvenient and affects the patient's treatment process.

[0004] Therefore, there is an urgent need to provide a suture device that allows for easy adjustment of suture force to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a suture device that is easy to adjust the suturing force.

[0006] To solve the above-mentioned technical problems, the present invention provides a suture device that facilitates adjustment of suture force, comprising an easy-tear film, a first hydrocolloid composite film fixedly installed on one side of the top of the easy-tear film, a second hydrocolloid composite film fixedly installed on the other side of the top of the easy-tear film, a tearing part fixedly installed on one side of both the first and second hydrocolloid composite films, a suture mechanism provided at the top of the first and second hydrocolloid composite films, an adjustment mechanism provided inside the suture mechanism, a fixing mechanism provided inside the suture mechanism, and an easy-tear groove provided on one side of the easy-tear film.

[0007] Using the above technical solution, hold the tear-off portion of the first hydrocolloid composite film and the second hydrocolloid composite film by hand, and divide the easy-tear film into two parts through the easy-tear grooves. Tear off one part from the first hydrocolloid composite film and the second hydrocolloid composite film, and then adhere the first hydrocolloid composite film and the second hydrocolloid composite film to both sides of the skin incision. Then tear off the remaining easy-tear film, and suture the two sides of the skin incision through the first hydrocolloid composite film and the second hydrocolloid composite film.

[0008] The present invention is further configured such that: the sewing mechanism includes a first fixing shell fixed to the top of the first hydrocolloid composite membrane, and a second fixing shell is fixedly installed on the top of the second hydrocolloid composite membrane.

[0009] The above technical solution adjusts the distance between the first hydrocolloid composite membrane and the second hydrocolloid composite membrane by using the first and second fixing shells.

[0010] The present invention is further configured such that: two tie rod racks are slidably installed inside the first fixed shell and the second fixed shell, and anti-pressure shells are fixedly installed at the top of both the first fixed shell and the second fixed shell.

[0011] Through the above technical solution, the tie rod rack adjusts the distance between the first fixed shell and the second fixed shell.

[0012] The present invention is further configured such that: the adjusting mechanism includes a first rotating rod rotatably mounted inside the first fixed shell, and a second rotating rod rotatably mounted inside the first fixed shell.

[0013] Through the above technical solution, the first rotating rod and the second rotating rod inside the first fixed shell can rotate respectively.

[0014] The present invention is further configured such that: both the first rotating rod and the second rotating rod are equipped with mounting gears on their exteriors, the outer surface of the mounting gears meshes with one side of the pull rod rack, and a cylindrical spring is fixedly installed on the inner wall of the first fixed shell, the interior of the cylindrical spring being rotatably connected to the outer surface of the first rotating rod.

[0015] Through the above technical solution, the first rotating rod and the second rotating rod are moved by the rack and pinion driven by the installed gears, and the cylindrical spring is driven by the installed gears to extend the first rotating rod upward.

[0016] The present invention is further configured such that: the fixing mechanism includes a rotating pressure plate fixed to one end of the first rotating rod, and a hexagonal block is fixedly installed at the other end of the first rotating rod.

[0017] Through the above technical solution, the rotating pressure plate drives the first rotating rod and the hexagonal block to rotate, and the anti-pressure shell prevents the rotating pressure plate from being pressed down by external forces.

[0018] The present invention is further configured such that: a hexagonal groove is provided inside the first fixed shell, and the inside of the hexagonal groove is fitted and installed with the outside of the hexagonal block; a circular groove is provided inside the first fixed shell, and the inside of the circular groove is rotatably connected with the outside of the hexagonal block.

[0019] With the above technical solution, the first rotating rod cannot rotate when the hexagonal block is inside the hexagonal groove, and the first rotating rod can rotate when the hexagonal block is inside the circular groove.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model, by providing a suturing mechanism and an adjustment mechanism, allows medical personnel to directly adjust from one side of the skin incision during operation, without having to adjust from both sides of the wound as in traditional methods. This greatly reduces operation time and difficulty, and can significantly improve suturing efficiency, especially in emergency medical situations or scenarios where rapid wound treatment is required.

[0022] 2. This utility model, by providing an adjustment mechanism and a fixing mechanism, eliminates the need for additional fixing operations after medical staff have adjusted the suture mechanism to the appropriate position. This reduces the errors that may be caused by fixing operations, making the suture process smoother and more efficient. It can reliably maintain the adjusted suture length and reduce hand fatigue for medical staff. Attached Figure Description

[0030] Please see Figures 1-5 A suture device for easy adjustment of suturing force includes an easy-tear film 1, a first hydrocolloid composite film 2 fixedly installed on one side of the top of the easy-tear film 1, and a second hydrocolloid composite film 3 fixedly installed on the other side of the top of the easy-tear film 1. A tearing part 4 is fixedly installed on one side of both the first hydrocolloid composite film 2 and the second hydrocolloid composite film 3. An easy-tear groove 8 is formed on one side of the easy-tear film 1. A suturing mechanism 5 is provided at the top of the first hydrocolloid composite film 2 and the second hydrocolloid composite film 3. The suturing mechanism 5 includes a first fixing shell 501 fixed to the top of the first hydrocolloid composite film 2, and a second fixing shell 502 fixedly installed at the top of the second hydrocolloid composite film 3. Two tie rod racks 503 are slidably installed inside the first fixing shell 501 and the second fixing shell 502. The top of each fixed shell 502 is fixedly equipped with an anti-pressure shell 504. Holding the tear-off part 4 of the first hydrocolloid composite film 2 and the second hydrocolloid composite film 3, the easy-tear film 1 is divided into two parts by the easy-tear groove 8. One part is torn off from the first hydrocolloid composite film 2 and the second hydrocolloid composite film 3. The first hydrocolloid composite film 2 and the second hydrocolloid composite film 3 are then adhered to both sides of the skin incision. The remaining easy-tear film 1 is then torn off. The two sides of the skin incision are sutured by the first hydrocolloid composite film 2 and the second hydrocolloid composite film 3. The pull rod rack 503 adjusts the distance between the first fixed shell 501 and the second fixed shell 502. The distance between the first fixed shell 501 and the second fixed shell 502 is adjusted by the first fixed shell 501 and the second fixed shell 502.

[0031] like Figure 3 and Figure 4As shown, the sewing mechanism 5 is internally equipped with an adjustment mechanism 6. The adjustment mechanism 6 includes a first rotating rod 601 rotatably mounted inside the first fixed housing 501, and a second rotating rod 602 rotatably mounted inside the first fixed housing 501. Mounting gears 603 are mounted on the exterior of both the first and second rotating rods 601 and 602. The outer surface of the mounting gears 603 meshes with one side of the pull rod rack 503. A cylindrical spring 604 is fixedly mounted on the inner wall of the first fixed housing 501. The interior of the cylindrical spring 604 is rotatably connected to the outer surface of the first rotating rod 601. The first rotating rod 601 and the second rotating rod 602 inside the first fixed housing 501 can rotate respectively. The first rotating rod 601 and the second rotating rod 602 drive the pull rod rack 503 to move via the mounting gears 603, thereby adjusting the spacing between the first hydrocolloid composite membrane 2 and the second hydrocolloid composite membrane 3 through the first and second fixed housings 501 and 502. The cylindrical spring 604 drives the first rotating rod 601 to extend upwards via the mounting gears 603.

[0032] like Figures 3-5 As shown, the sewing mechanism 5 has a fixing mechanism 7 inside. The fixing mechanism 7 includes a rotating pressure plate 701 fixed to one end of the first rotating rod 601. A hexagonal block 702 is fixedly installed at the other end of the first rotating rod 601. A hexagonal groove 703 is opened inside the first fixing shell 501. The inside of the hexagonal groove 703 is fitted with the outside of the hexagonal block 702. A circular groove 704 is opened inside the first fixing shell 501. The inside of the circular groove 704 is rotatably connected to the outside of the hexagonal block 702. When the rotating pressure plate 701, the first rotating rod 601 and the hexagonal block 702 are pressed down by hand, the anti-pressure shell 504 prevents the rotating pressure plate 701 from being pressed down by other external forces. When the hexagonal block 702 is inside the hexagonal groove 703, the first rotating rod 601 cannot rotate. When the hexagonal block 702 is inside the circular groove 704, the first rotating rod 601 can rotate. The rotating pressure plate 701, the first rotating rod 601 and the hexagonal block 702 can be rotated by hand.

[0033] In use, this invention involves holding the tear-off portion 4 of the first hydrocolloid composite film 2 and the second hydrocolloid composite film 3 by hand, and dividing the easy-tear film 1 into two parts using the easy-tear groove 8. One part is torn off from the first hydrocolloid composite film 2 and the second hydrocolloid composite film 3, and then the first hydrocolloid composite film 2 and the second hydrocolloid composite film 3 are adhered to both sides of the skin incision. The remaining easy-tear film 1 is then torn off, and the two sides of the skin incision are sutured using the first hydrocolloid composite film 2 and the second hydrocolloid composite film 3. The rotating pressure plate 701, the first rotating rod 601, and the hexagonal block 702 are pressed downwards by hand. The anti-pressure shell 504 prevents the rotating pressure plate 701 from being pressed downwards by other external forces. When the hexagonal block 702 is located inside the hexagonal groove 703, the first rotating rod 601 cannot rotate. When the hexagonal block 702 is located inside the circular groove 704, the first rotating rod 601 cannot rotate. A rotating rod 601 can rotate. The rotating pressure plate 701, the first rotating rod 601, and the hexagonal block 702 can be rotated by hand. The first rotating rod 601 and the second rotating rod 602 inside the first fixed shell 501 can rotate respectively. The first rotating rod 601 and the second rotating rod 602 drive the pull rod rack 503 to move through the mounting gear 603. The pull rod rack 503 adjusts the distance between the first fixed shell 501 and the second fixed shell 502. The distance between the first hydrocolloid composite membrane 2 and the second hydrocolloid composite membrane 3 is adjusted through the first fixed shell 501 and the second fixed shell 502. The columnar spring 604 drives the first rotating rod 601 to extend upward through the mounting gear 603, so that the hexagonal block 702 is located inside the circular groove 704, and the adjusted length is fixed.
