Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a postoperative protective device for thyroid surgery. Background Technology

[0002] Thyroid surgery, as one of the important means of treating thyroid diseases, places great importance on the choice of incision location. Generally, the incision for thyroid surgery is located in the anterior neck, two finger-widths above the sternal notch, and is made in an arc shape along the skin crease. This incision design can minimize the visibility of postoperative scars. In addition, the length of the incision is determined based on factors such as the size of the thyroid nodule and whether lymph node dissection is required. If lymph node dissection is required, the incision may be extended appropriately to the same side, or even a large L-shaped incision may be needed.

[0003] In the existing technology, due to the unique shape of thyroid surgery wounds, it is difficult for postoperative protective devices to be suitable for all patients. They cannot effectively fix the skin around the wound and the dressing, which can easily lead to tearing of the skin around the wound or wound dehiscence, resulting in slower wound healing and more obvious scars. Summary of the Invention

[0004] The purpose of this invention is to provide a postoperative protective device for thyroid surgery, suitable for incisions of different lengths and large L-shaped incisions, to effectively fix the skin and dressings around the wound after surgery, which helps wound healing and reduces the degree of scarring.

[0005] To achieve the above objectives, the present invention provides a postoperative protective device for thyroid surgery, comprising a first upper protective plate, a second upper protective plate, a first lower protective plate, and a second lower protective plate. One end of the first upper protective plate is fixedly connected to one end of the second upper protective plate via a first sliding member, and one end of the first lower protective plate is fixedly connected to one end of the second lower protective plate via a second sliding member. The other end of the first upper protective plate is fixedly connected to the other end of the first lower protective plate via a first contracting member, and the other end of the second upper protective plate is fixedly connected to the other end of the second lower protective plate via a second contracting member. The interiors of the first upper protective plate, the second upper protective plate, the first lower protective plate, and the second lower protective plate are all hollow structures. Slide rails are provided on both sides of the first upper protective plate and the first lower protective plate. Limiting holes are provided at the ends of the first upper protective plate and the first lower protective plate near the slide rails. The first sliding member includes a slider disposed at the end of the second upper protective plate and a limiting block corresponding to the limiting hole. The slider is slidably connected to the slide rail.

[0006] Preferably, the length of the slide rail is less than half the length of the first upper protective plate.

[0007] Preferably, the second sliding member has the same structure as the first sliding member, the peripheral wall of the limiting block is provided with a pawl, the pawl is inclined, and the inner wall of the limiting hole is provided with a serrated rack that meshes with the pawl.

[0008] Preferably, the second shrinking member has the same structure as the first shrinking member. The first shrinking member includes a first rotating rod, a second rotating rod, and a fixing rope. The ends of the first upper protective plate and the first lower protective plate are provided with hollow shells. The bottom end of the first rotating rod is rotatably connected to the inner wall of the hollow shell. The top end of the first rotating rod passes through the top surface of the hollow shell and the first upper protective plate in sequence. A knob is provided at the through end of the first rotating rod. The second rotating rod is disposed on the first lower protective plate. The two ends of the fixing rope pass through the hollow shell and are fixedly connected to the first rotating rod and the second rotating rod, respectively.

[0009] Preferably, the knob is provided with a locking buckle.

[0010] Preferably, the cavity structure is filled with a first adhesive layer, the thickness of which is equal to the depth of the cavity structure.

[0011] Preferably, it also includes a dressing, which is fixedly connected to the top surfaces of the first upper protective plate, the second upper protective plate, the first lower protective plate, and the second lower protective plate respectively via connectors.

[0012] Preferably, the connector includes a first Velcro strip disposed around the dressing, and the top surfaces of the first upper protective plate, the second upper protective plate, the first lower protective plate, and the second lower protective plate are all provided with a second Velcro strip that is adhered to the first Velcro strip.

[0013] Preferably, a rubber tube is fitted onto the fixing rope, and both ends of the rubber tube are connected to the outer wall of the hollow shell. A second adhesive layer is provided on the rubber tube, and the length of the second adhesive layer is greater than the length of the rubber tube.

[0014] Therefore, the present invention employs the above-mentioned postoperative protective device for thyroid surgery, and the beneficial effects are as follows: This invention, by setting a first upper protective plate and a second upper protective plate, extends the second upper protective plate to a set length along the direction of the first upper protective plate, making it suitable for incisions of different lengths. When the limiting block of the second upper protective plate engages with the limiting hole, the angle of the second upper protective plate can be adjusted, making it suitable for large L-shaped incisions. This ensures effective fixation of the skin and dressings around the postoperative wound, promotes wound healing, and meets the postoperative protection needs of various types of thyroid surgeries.

[0015] This invention uses pressure-sensitive adhesive to fix the first upper protective plate, the second upper protective plate, the first lower protective plate, and the second lower protective plate. Velcro is used to fix the dressing, making it convenient for doctors or patients to change the dressing regularly. The protective plates can be fixed to the skin around the patient's wound for a long time. The distance between the upper and lower protective plates can be adjusted by turning a knob, which has a tension-reducing effect and helps to reduce the visibility of scars.

[0019] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0021] Example 1 like Figures 1-5As shown, a postoperative protective device for thyroid surgery includes a first upper protective plate 1, a second upper protective plate 2, a first lower protective plate 3, a second lower protective plate 4, and a dressing 5. The first upper protective plate 1, the second upper protective plate 2, the first lower protective plate 3, and the second lower protective plate 4 are placed on the skin around the wound. The center of the dressing 5 corresponds to the wound position. The periphery of the dressing 5 is fixedly connected to the top surfaces of the first upper protective plate 1, the second upper protective plate 2, the first lower protective plate 3, and the second lower protective plate 4 via connectors. Specifically, the connectors include first Velcro 6 disposed around the dressing 5, and second Velcro 7 adhering to the first Velcro 6 on the top surfaces of the first upper protective plate 1, the second upper protective plate 2, the first lower protective plate 3, and the second lower protective plate 4. The Velcro 7 secures the dressing 5, facilitating regular changes of the dressing 5 by the doctor or patient. The dressing 5 is a surgical-specific medication or a waterproof dressing. Both the dressing 5 and the first Velcro 6 are cut to meet various usage requirements.

[0022] The first upper protective plate 1, the second upper protective plate 2, the first lower protective plate 3, and the second lower protective plate 4 all have hollow internal structures, filled with a first adhesive layer 8. The thickness of the first adhesive layer 8 is equal to the depth of the hollow structure. The first adhesive layer 8 is a pressure-sensitive adhesive, which allows the first upper protective plate 1, the second upper protective plate 2, the first lower protective plate 3, and the second lower protective plate 4 to be fixed to the skin around the patient's wound for a long time.

[0023] One end of the first upper protective plate 1 is fixedly connected to one end of the second upper protective plate 2 via the first sliding member 9, and one end of the first lower protective plate 3 is fixedly connected to one end of the second lower protective plate 4 via the second sliding member 10. The first sliding member 9 and the second sliding member 10 have the same structure.

[0024] Specifically, both sides of the first upper protective plate 1 and the first lower protective plate 3 are provided with slide rails 11, and the length of the slide rail 11 is less than half the length of the first upper protective plate 1. The ends of the first upper protective plate 1 and the first lower protective plate 3 near the slide rails 11 are provided with limit holes 12. Taking the first sliding member 9 as an example, the first sliding member 9 includes a slider 13 disposed at the end of the second upper protective plate 2 and a limit block 14 corresponding to the limit hole 12. The slider 13 is slidably connected to the slide rail 11.

[0025] The peripheral wall of the limiting block 14 is provided with a pawl 15, which is inclined. The inner wall of the limiting hole 12 is provided with a serrated rack 16 that meshes with the pawl 15. That is, the limiting block 14 is allowed to rotate in one direction (i.e., counterclockwise), while resistance is formed in the clockwise direction. So when the limiting block 14 enters the limiting hole 12, the serrated rack 16 on the limiting hole 12 and the pawl 15 inside the limiting block 14 engage with each other. When the limiting block 14 rotates counterclockwise by a set angle, the pawl 15 tightly grips the serrated rack 16, preventing the limiting block 14 from rotating back.

[0026] The other end of the first upper protective plate 1 is fixedly connected to the other end of the first lower protective plate 3 via the first retractable member 17, and the other end of the second upper protective plate 2 is fixedly connected to the other end of the second lower protective plate 4 via the second retractable member 18. Specifically, the second retractable member 18 has the same structure as the first retractable member 17. Taking the first retractable member 17 as an example, the first retractable member 17 includes a first rotating rod 19, a second rotating rod 20, and a fixing rope 21. Both the first upper protective plate 1 and the first lower protective plate 3 have hollow shells 22 at their ends. The bottom end of the first rotating rod 19 is rotatably connected to the inner wall of the hollow shell 22, and the top end of the first rotating rod 19 passes through the hollow shell 22 and the top surface of the first upper protective plate 1 in sequence. A knob 23 is provided at the through end of the first rotating rod 19, and a locking buckle 24 is provided on the knob 23 to fix the first rotating rod 19. Similarly, the second rotating rod 20 is provided on the first lower protective plate 3, and the knob 23 can fix the second rotating rod 20.

[0027] The two ends of the fixing rope 21 pass through the hollow shell 22 and are fixedly connected to the first rotating rod 19 and the second rotating rod 20 respectively. Rotating the knob 23 can rewind the fixing rope 21, which has the effect of a tension reducer. A rubber tube 25 is sleeved on the fixing rope 21. The two ends of the rubber tube 25 are connected to the outer wall of the hollow shell 22. A second adhesive layer 26 is provided on the rubber tube 25. The length of the second adhesive layer 26 is greater than the length of the rubber tube 25. The second adhesive layer 26 is medical tape, which meets the requirements of fixing the position of the fixing rope 21 and waterproofing.

[0028] In actual use, firstly, adjust the extension length of the second upper protective plate 2 or the rotation angle between the first upper protective plate 1 and the second upper protective plate 2 according to the length and shape of the incision. This operation should be performed by a professional doctor or nurse to avoid excessive differences between the length or angle and the wound shape. Secondly, remove the anti-adhesive material from the surface of the first adhesive layer 8, fix the protective plate around the wound skin, and then turn the knob 23 to tighten the fixing rope 21. Then, remove the anti-adhesive material from the surface of the second adhesive layer 26 and fix the rubber tube 25 around the wound skin. Next, place the dressing 5 on the wound site and fix the dressing 5 to the protective plate with Velcro. Finally, check the wound condition regularly and change the dressing 5.

[0029] Therefore, the present invention employs the above-mentioned postoperative protective device for thyroid surgery, which is suitable for incisions of different lengths and large L-shaped incisions, and satisfies the need for effective fixation of the skin and dressings around the postoperative wound, which helps wound healing and reduces the degree of scarring.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
