Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a painless progressive incision closure device. Background Technology

[0002] In the medical field, surgery usually requires making incisions on the patient's body, and the incisions are usually closed by suturing after the operation.

[0003] However, both silk and absorbable sutures present some challenges during the suturing process. With silk sutures, the outer skin layer may not align accurately, resulting in an uneven surgical incision. Furthermore, suture removal is necessary after the incision has healed, a process that can cause pain for the patient. With absorbable sutures, excessive suture embedding can negatively impact wound healing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a painless progressive incision closure device, primarily comprising an incision closure unit, a current-guiding component, a control device, and a tension band. Human skin continuously radiates heat to the outside world. When the tension band is heated, its length gradually contracts, causing the two incision closure units to slowly bring the skin on both sides of the incision together. During this process, the control device guides the electrode plates in the current-guiding component to release a weak current, thereby blocking the transmission of pain signals to the patient's nerves. Compared to existing technologies, this invention eliminates the pain during incision healing, improves the healing effect to a certain extent, and enhances the patient's experience, thus possessing high practicality.

[0049] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0050] Example 1

[0051] As attached Figures 1-3 As shown, this embodiment discloses a painless progressive incision closure device to eliminate pain during incision healing. It mainly includes an incision closure unit 2, a current-conducting component 1, a control device 5, and a tension band 4. In use, first, the side of this embodiment containing the adhesive layer 3 faces the patient; then, the notch in the middle of this embodiment (not marked in the figure) is aligned with the patient's incision. This notch is located in the area directly below the center of the tension band 4, as shown in the attached figure. Figure 1 As shown, this avoids contact between the incision and the adhesive layer 3. At this time, the incision closure unit 2 and the current-conducting member 1, under the action of the adhesive layer 3, can adhere tightly to the patient's skin. To maintain the patient's body temperature balance, the patient's skin will continuously radiate heat outwards, and this heat can be transferred to the tension band 4 via the incision closure unit 2. Since the tension band 4 is made of shape memory alloy, when the tension band 4 receives heat radiated from the patient's skin, its length will gradually contract, thus moving the incision closure unit 2 at one end of the tension band 4 in the first direction A1 and the incision closure unit 2 at the other end of the tension band 4 in the second direction B1, as shown in the attached diagram. Figure 1 As shown; at the same time, the skin on both sides of the incision slowly closes towards the middle, and the incision gradually heals; during the incision healing process, the control device 5 is activated to guide the electrode plate 12 in the current guiding component 1 to release a weak current to the skin near the patient's incision, so as to block the transmission of the patient's pain nerves, that is, to eliminate the pain generated during the incision healing. This design enhances the patient's user experience to a certain extent.

[0052] Of course, in practice, medical staff can inject medication into the patient's incision to help it heal. This medication, combined with the patient's own self-healing system, can further improve the healing effect of the incision.

[0053] Medical staff can understand that if the patient's pain nerves are not blocked during the wound healing process, the patient will continue to feel pain caused by the skin on both sides of the incision coming together. At this time, some patients will experience tension, which will lead to muscle tension and generally reduce the effectiveness of wound healing.

[0054] The specific structure of the painless progressive incision closure device is as follows: There are two incision closure units 2, one side of which is provided with an adhesive layer 3; a current guiding member 1 is provided between the two incision closure units 2, and the current guiding member 1 has an installation unit 11, one side of which is also provided with an adhesive layer 3; an electrode plate 12 is provided on the side of the installation unit 11 containing the adhesive layer; the current guiding member 1 is electrically connected to a control device 5; a tension band 4 is provided on the side of the incision closure unit 2 facing away from the adhesive layer, with both ends of the tension band 4 passing through the interior of the two incision closure units 2, and the tension band 4 is made of shape memory alloy; when heated, the length of the tension band 4 gradually shrinks. Compared with the prior art, this invention eliminates the pain during incision healing, improves the healing effect of the incision to a certain extent, and enhances the patient's user experience, thus possessing high practicality.

[0055] In a specific application scenario, as shown in the appendix Figure 1 As shown, there are three stretch bands 4. This design can enhance the effect of the skin on both sides of the incision closing together.

[0056] In a specific application scenario, as shown in the appendix Figure 2As shown, the current guiding component 1 also includes a temperature sensor 13. This temperature sensor 13 is located on the side of the mounting unit 11 containing the adhesive layer 3, on the side of the electrode plate 12, and approximately in the middle of the length of the mounting unit 11. The electrode plate 12 is positioned between the temperature sensor 13 and the adhesive layer 3. Normally, the temperature sensor 13 is electrically connected to the control device 5. During the incision healing process, the temperature sensor 13 converts the heat emitted by the patient's skin into a corresponding temperature value, which is transmitted to the control device 5 in real time. If the temperature value is within a preset range, the healing effect of the incision can be improved. If the control device 5 detects through the temperature sensor 13 that the current temperature value exceeds the preset range, it indicates inflammation at the incision site, i.e., bacterial infection. The display screen (not marked in the figure) of the control device 5 will display the corresponding information. At this time, medical personnel need to take appropriate measures to ensure the patient's safety. This design achieves the purpose of real-time monitoring of the incision healing status. Of course, the preset range mentioned in this paragraph can be adjusted by medical personnel to suit the current healing status of the patient's incision. In addition, staff can electrically connect an alarm (not shown in the figure) to the control device 5; if the temperature emitted by the patient's skin exceeds the preset range, the control device 5 sends a command to the alarm to start working, the alarm sounds, and nearby medical staff can quickly obtain the corresponding information about the current patient.

[0057] In a specific application scenario, as shown in the appendix Figure 2 As shown, the current guiding component 1 also includes a gel guiding component 14; wherein, the gel guiding component 14 is disposed on the side of the mounting unit 11 containing the adhesive layer 3, and the gel guiding component 14 is located between the electrode sheet 12 and the temperature sensor 13, and there are two of them; under normal circumstances, the gel guiding component 14 is electrically connected to the control device 5; the aforementioned mounting unit 11 contains gel. In use, the control device 5 can issue an open or close command to the gel guiding component 14 according to the temperature at the incision site, thereby allowing the gel in the mounting unit 11 to be injected into the skin near the incision under appropriate conditions, thereby enhancing the incision healing effect. For example, if the temperature sensor 13 detects that the current temperature of the incision is within the normal range, it indicates that the incision is healing normally. At this time, the gel guiding component 14 can be opened, and an appropriate amount of gel can be injected into the skin near the incision through the mounting unit 11.

[0058] Furthermore, the gel guiding component 14 mainly includes a gel guiding hole 141 and a sealing element 142. Specifically, the gel guiding hole 141 is opened on the side of the mounting unit 11 containing the adhesive layer 3; the sealing element 142 is slidably disposed on one side of the gel guiding hole 141; normally, the sealing element 142 is electrically connected to the control device 5. In use, the control device 5 can issue an opening or closing command to the sealing element 142, thereby changing the opening and closing status of the gel guiding hole 141, thus precisely controlling the outflow of gel in the mounting unit 11, which to a certain extent enhances the healing effect of the incision.

[0059] Furthermore, the gel in the mounting unit 11 can be a hyaluronic acid hydrogel; the hyaluronic acid hydrogel can create a moist healing environment, a design that can both promote cell proliferation and inhibit scar formation, thereby synergistically accelerating the incision healing process. In addition, the gel can improve the conductivity of the patient's skin, thereby enhancing the effect of blocking pain nerve transmission.

[0060] In a specific application scenario, as shown in the appendix Figure 1 As shown, the control device 5 mainly includes a controller 51 and a connecting wire 52; wherein, the controller 51 is disposed on one side of the current guiding member 1; the controller 51 is provided with a connecting wire 52 on the side facing the current guiding member 1, and one end of the connecting wire 52 is connected to the current guiding member 1. This design facilitates the transmission of corresponding data and current. For example, the controller 51 can transmit the current required for the normal operation of the electrode plate 12 through the connecting wire 52, and the temperature data detected by the temperature sensor 13 can be transmitted to the controller 51 through the connecting wire 52.

[0061] Furthermore, the controller 51 can be a transcutaneous nerve stimulator; wherein, the transcutaneous nerve stimulator can transmit the corresponding current to the electrode pad 12 more accurately, thereby enhancing the wound healing effect to a certain extent.

[0062] In a specific application scenario, as shown in the appendix Figure 1 As shown, the end face of the mounting unit 11 along its length is collinear with the end face of the incision closure unit 2 along its length, which is the same horizontal ray. That is, the length of the mounting unit 11 is equal to the length of the incision closure unit 2. During the process of the two incision closure units 2 bringing the skin on both sides of the incision together, since the length of the incision closure unit 2 is equal to the length of the mounting unit 11, the probability of skin wrinkling can be reduced, thereby improving the incision healing effect.

[0063] In a specific application scenario, there are two current-conducting components 1, located on opposite sides of the two cut-off closing units 2, i.e., there are two connecting wires 52, so that the controller 51 can maintain the normal operation of the corresponding components in the two current-conducting components 1. In use, this embodiment can evenly release a weak current on both sides of the cut, which can improve the effect of blocking the transmission of pain nerves.

[0064] This embodiment also considers a situation, the specific solution of which is as follows: a protective layer 6 is provided on the side of the tension band 4 facing away from the cut-off closing unit 2, and the area of ​​the protective layer 6 is greater than or equal to the sum of the areas of the cut-off closing unit 2 and the current guiding member 1, as shown in the attached figure. Figure 3 As shown, this design can reduce the probability of external bacteria invading the incision. Normally, the protective layer 6 is provided with the aforementioned adhesive layer 3 on the side facing the stretch band 4. This adhesive layer 3 can prevent the protective layer 6 from moving away from the installation incision closure unit 2, thereby maintaining the effect of resisting bacteria.
