Non-invasive suturing device and method of use thereof

Abstract

The present invention discloses a non-invasive suturing device and a method of using the same, which belong to the field of medical devices. The non-invasive suturing device includes a first patch, a second patch, an adjustment component and a wound eversion component, which are respectively pasted on both sides of a wound to be sutured. The wound eversion component is used in conjunction with the adjustment component. When the adjustment drive drives the first patch and the second patch to approach each other, the flap upward drive of the wound eversion component can simultaneously drive the first flap and the second flap upward, so that the two sides of the wound to be sutured are symmetrically everted, so that the wound tissues on both sides of the wound can better contact and fit together. Since the wound / wound is everted for fitting, the scar formed by the present invention is smaller and smoother, or even has no obvious scar, compared with the suturing devices combined with flat pulling on the market. The present invention is suitable for non-invasive suturing of surgical incision skin or wound skin in plastic surgery.

Description

Technical Field

[0001] The present invention belongs to the field of medical devices and relates to suturing devices, in particular to a non-invasive suturing device and a method of using the same. Background Art

[0002] Traditional skin wound suturing is done with needles, thread and staples, which can cause secondary damage to the skin and form scars on both sides of the wound.

[0003] In order to overcome the above defects, some wound closing devices have appeared on the market, which can help the wound to be pulled flat and closed during the suturing process, such as the skin wound closing device disclosed in the Chinese patent application number 201520784070.0, which includes a draw buckle, medical tape and release paper. The draw buckle includes a cable tie, a lock buckle and a base sheet. The cable tie, the lock buckle and the base sheet are an integrated structure. The base sheet is connected to the reinforcing layer. The medical tape includes two layers. Part of the base sheet and the entire reinforcing layer are bonded and fixed between the two layers of medical tape. The medical tape is bonded to the release paper. Ratchets are provided on both sides of the cable tie. Correspondingly, a guide groove is provided in the lock buckle. The ratchets on both sides of the cable tie and the guide groove in the lock buckle are used in combination. The ratchets can be clamped on the guide groove to adjust the suturing tightness of the draw buckle.

[0004] However, existing wound closure devices are mostly used for flat wound sutures, which leave significant scars and are suitable for skin suturing in general surgery. Plastic surgery requires smaller, smoother scars, or even scarless, wound closures. However, current wound closure devices do not meet these requirements. Therefore, there is a need for a wound closure device suitable for non-invasive suturing of surgical incisions or wounds in plastic surgery. Summary of the Invention

DETAILED DESCRIPTION

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0051] One of the purposes of the present invention is to provide a non-invasive suturing instrument to solve the problem that existing wound suturing aids have obvious scarring and cannot meet the requirements of wound suturing in plastic surgery.

[0052] Another object of the present invention is to provide a method for using the above-mentioned non-invasive suturing device.

[0053] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] Example 1

[0055] like Figures 1 to 6As shown, this embodiment provides a non-invasive suturing device 100, which mainly includes an adjustment component, a wound eversion component, and a first patch 1 and a second patch 2 for respectively attaching to the two sides of the wound to be sutured. Among them, the adjustment component includes a first main seat 3, a second main seat 4 and an adjustment drive. The first main seat 3 and the second main seat 4 are respectively arranged on the upper surface of the first patch 1 and the upper surface of the second patch 2. The adjustment drive is connected to at least one of the first main seat 3 and the second main seat 4, and is used to adjust the distance between the first patch 1 and the second patch 2, thereby making the first patch 1 and the second patch 2 closer to each other or farther away from each other, which can adapt to wounds of different wound areas. In actual use, the adjustment drive is mainly used to bring the first patch 1 and the second patch 2 closer to each other. The wound eversion assembly includes a first flap 5, a second flap 6, and a flap-up drive. The first flap 5 is provided on the upper surface of the first patch 1 and is located at the end of the first patch 1 close to the wound to be sutured. The second flap 6 is provided on the upper surface of the second patch 2 and is located at the end of the second patch 2 close to the wound to be sutured. The first flap 5 and the second flap 6 are both connected to the flap-up drive. When the drive is adjusted to drive the first patch 1 and the second patch 2 to approach each other, the flap-up drive can simultaneously drive the first flap 5 and the second flap 6 to flip upward, so that the two sides of the wound to be sutured are symmetrically everted and affixed. The non-invasive suturing device 100 of this embodiment can better contact the wound tissues on both sides of the wound by everting and affixing the two sides of the wound. It can meet the requirements of plastic surgeons in suturing technology for everting closure, tension-free, dead space-free, and sterile wound treatment, making the postoperative scar smaller and smoother, or even without obvious scars. It is suitable for non-invasive suturing of surgical incision skin or wound skin in plastic surgery.

[0056] In this embodiment, the aforementioned first patch 1 and second patch 2 can be medical tapes with self-adhesive properties, or they can be soft sheets without adhesive properties, which can be attached to the skin with the help of tape. Taking into account the convenience of storage, carrying and use, the aforementioned first patch 1 and second patch 2 in this embodiment are preferably medical tapes with self-adhesive properties, and the adhesive surface of the medical tape is the lower surface, and the lower surface of the medical tape is affixed with release paper 7. The upper surface of the medical tape serves as a bearing surface, carrying the above-mentioned adjustment component and wound eversion component. When needed, the release paper 7 on the lower surface of the first patch 1 and the second patch 2 can be torn off and attached to the skin.

[0057] In this embodiment, it is preferred that the adhesive surfaces of the first patch 1 and the second patch 2 are attached to the same release paper 7. Figure 1 and Figure 2As shown, the release paper 7 can be rectangular, and the entire non-invasive suturing device 100 is located at the center of the release paper 7. Two dividing lines 71 are arranged on the release paper 7 along its length direction to divide the release paper 7 into a first area 72, a second area 73 and a third area 74 in sequence along its length direction. The adhesive surface of the first patch 1 is applied to the first area 72 and covers part of the second area 73. The adhesive surface of the second patch 2 is applied to the third area 74 and covers part of the second area 73. The first patch 1 and the second patch 2 can be bonded to the release paper 7 in the second area 73 or not. In this technical solution, the lower surface of the first patch 1 where the first flap 5 is set and the lower surface of the second patch 2 where the second flap 6 is set are both bonded to the second area 73. The aforementioned dividing line 71 can be a punched dotted line (also known as a "cliff line") or a solid dividing line. The setting of the dividing line is to facilitate the separate tearing off of the release paper 7 in the second area 73, and to ensure the integrity of the release paper 7 when not in use, so as to support the entire non-invasive suturing device 100 and ensure the cleanliness of the bottom adhesive surface of the non-invasive suturing device 100.

[0058] In this embodiment, the adjustment drive of the adjustment component can be a screw slider mechanism, a telescopic rod, a top screw, etc., and can be in the form of unilateral drive or bilateral drive. When unilaterally driven, the adjustment drive generally only drives one of the first main seat 3 and the second main seat 4. When bilaterally driven, the adjustment drive drives the first main seat 3 and the second main seat 4 at the same time. As a preferred solution, the adjustment drive of this embodiment adopts a screw slider mechanism, which includes an adjustment screw 8 and a threaded hole that cooperates with the adjustment screw 8. The first end of the adjustment screw 8 is provided with a threaded section 81. The above-mentioned threaded hole is provided on the first main seat 3. The threaded section 81 is threadedly connected to the threaded hole of the first main seat 3. The second end of the adjustment screw 8 is provided as a light rod section. The light rod section is provided through the second main seat 4, and the light rod section can rotate relative to the second main seat 4. As shown Figures 1 to 4 As shown, the limit block 82 is arranged at the second end of the adjusting screw 8 and cooperates with the side of the second main seat 4 away from the first main seat 3. When the threaded section 81 of the adjusting screw 8 is screwed into the threaded hole of the first main seat 3, the limit block 82 can push the second main seat 4 closer to the first main seat 3. Since the first main seat 3 and the second main seat 4 are respectively fixed to the first patch 1 and the second patch 2, the second patch 2 is also brought closer to the first patch 1, thereby achieving the effect of adjusting the distance between the first patch 1 and the second patch 2.

[0059] In this embodiment, the aforementioned limit block 82 can be set as a rectangular block, and the side of the second main seat 4 away from the first main seat 3 is set to be flat, and the limit block 82 and the second main seat 4 are in plane contact fit. In addition, the limit block 82 can also be set as a limit chuck, which is a cylindrical structure, and the side of the second main seat 4 away from the first main seat 3 is provided with a groove that can accommodate the limit chuck, and the two are in a concave-convex structure fit, but the groove does not limit the rotation of the limit chuck. Compared with the first type of plane contact fit, setting the limit block 82 as a limit chuck with a cylindrical structure and matching it with the concave-convex groove on the second main seat 4 can ensure the relative position relationship between the limit block 82 and the second main seat 4, and prevent the limit block 82 from being offset relative to the second main seat 4 during the rotation of the adjusting screw 8.

[0060] In this embodiment, the flap-up drive can be a direct drive structure such as a telescopic rod and a traction rope, or it can be an indirect drive structure used in conjunction with the aforementioned adjustment component. When the telescopic rod is used as the direct drive mechanism, the telescopic rod can be considered to be installed on the first main seat 3 and the second main seat 4, and the flap is driven to flip up by the telescopic rod while the first patch and the second patch are moving, or after the first patch and the second patch are moved to the appropriate position; when the traction rope is used as the direct drive mechanism, the traction rope is manually pulled, and the flap is driven to flip up by manually pulling the traction rope while the first patch and the second patch are moving, or after the first patch and the second patch are moved to the appropriate position.

[0061] Although the above-mentioned direct drive mechanism can realize the upward flipping of the flap, its structure is relatively complicated. In order to further simplify the structure, this embodiment preferably sets the flap upward flipping drive to an indirect drive structure that can be used in conjunction with the above-mentioned adjustment component. The indirect drive structure mainly includes a first guide component and a second guide component, wherein the first guide component includes a first connecting rod 9 and a first guide groove 10, one end of the first connecting rod 9 is connected to the first flap 5, the first guide groove 10 is opened on the second main seat 4, and the first guide groove 10 is inclined upward from the side of the second main seat 4 close to the first main seat 3 to the side of the second main seat 4 away from the first main seat 3, so as to Figure 3Taking the positional relationship shown in as an example, the second main seat 4 is located on the right side of the entire non-invasive suturing instrument 100, and the first guide groove 10 is tilted upward from left to right on the second main seat 4. The other end of the first connecting rod 9 slides with the first guide groove 10. In the process of the first patch 1 and the second patch 2 approaching each other, the first connecting rod 9 can slide to the right along the first guide groove 10 and move obliquely upward under the guidance of the first guide groove 10, thereby driving the first flap 5 to tilt up and turn one side of the wound outward. Correspondingly, the second guide assembly includes a second connecting rod 11 and a second guide groove 12. One end of the second connecting rod 11 is connected to the second flap 6. The second guide groove 12 is opened on the first main seat 3, and the second guide groove 12 is tilted upward from the side of the first main seat 3 close to the second main seat 4 to the side of the first main seat 3 away from the second main seat 4, so as to Figure 4 Take the positional relationship shown in as an example to illustrate, the first main seat 3 is located on the right side of the entire non-invasive suturing device 100, and the second guide groove 12 is arranged on the first main seat 3 from left to right and tilted upward. The other end of the second connecting rod 11 slides with the second guide groove 12. In the process of the first patch 1 and the second patch 2 approaching each other, the second connecting rod 11 can slide to the right along the second guide groove 12 and move obliquely upward under the guidance of the second guide groove 12, thereby driving the second flap 6 to tilt up and turn the other side of the wound outward. The above-mentioned flap upward turning drive can drive the first flap 5 and the second flap 6 to tilt symmetrically, thereby driving the two sides of the wound to flip up symmetrically, so that the wound tissues on both sides can better contact each other.

[0062] In this embodiment, the first connecting rod 9 and the first guide groove 10 can be a square groove and a square rod, or a round rod and a round groove. Similarly, the second connecting rod 11 and the second guide groove 12 can be a square groove and a square rod, or a round rod and a round groove.

[0063] In this embodiment, Figure 1 、 Figure 3 and Figure 4 As shown, the first main seat 3 and the second main seat 4 are both half-cut cylindrical seats, and the section (plane) of the first main seat 3 is arranged opposite to the section (plane) of the second main seat 4. The first connecting rod 9 and the second connecting rod 11 are respectively located on both sides of the axial direction of the adjusting screw 8.

[0064] In this embodiment, the first main seat 3 and the first flip plate 5 are both integrally formed with the first patch 1 ; the second main seat 4 and the second flip plate 6 are both integrally formed with the second patch 2 .

[0065] In this embodiment, Figure 1 and Figure 2 As shown, the first flap 5 and the second flap 6 are both "mountain" shaped frame, and the opening end of the first flap 5 and the opening end of the second flap 6 are arranged away from each other.

[0066] In this embodiment, Figure 1 、 Figure 3 and Figure 4 As shown, the first connecting rod 9 is a first "L"-shaped connecting rod, and one end of the first "L"-shaped connecting rod is connected to the first flap 5, and the other end is slidingly engaged with the first guide groove 10; correspondingly, the second connecting rod 11 is a second "L"-shaped connecting rod, and one end of the second "L"-shaped connecting rod is connected to the second flap 6, and the other end is slidingly engaged with the second guide groove 12.

[0067] In this embodiment, the aforementioned first main seat 3, second main seat 4, adjusting screw 8, first connecting rod 9, first flap 5, second connecting rod 11, and second flap 6 are preferably made of polypropylene; among them, the first connecting rod 9 and the first flap 5 are preferably integrally formed, and the second connecting rod 11 and the second flap 6 are preferably integrally formed.

[0068] The following is a detailed description of the operating principle of the non-invasive suturing device 100 of this embodiment.

[0069] In the non-invasive suturing device 100 of this embodiment, the first area release paper base plate (i.e., the first area 72 of the release paper 7), the second area release paper base plate (i.e., the second area 73 of the release paper 7), and the third area release paper base plate (i.e., the third area 74 of the release paper 7) are arranged in sequence from left to right, and the second area release paper base plate (i.e., the second area 73 of the release paper 7) and the first area release paper base plates (i.e., the first area 72 of the release paper 7) and the third area release paper base plates (i.e., the third area 74 of the release paper 7) on both sides are connected with a cliff point, which can be easily torn apart. During operation, it is necessary to tear off the middle release paper base plate (i.e., the second area 73 of the release paper 7) first, and then rotate the adjusting screw 8 according to the distance between the outer edges of the wound to be sutured to appropriately reduce the distance "T" between the first main seat 3 and the second main seat 4, thereby ensuring that the distance "t" between the first flap 5 and the second flap 6 can meet the wound area to be sutured and the eversion effect of the flap on the skin on both sides of the wound, as shown in FIG. Figure 2As shown, the first flap 5 and the second flap 6 are respectively arranged at the edge positions of the first patch 1 and the second patch 2. The spacing "t" between the first flap 5 and the second flap 6 can also represent the distance between the first patch 1 and the second patch 2. In general, the first patch 1 and the second patch 2 are symmetrically or approximately symmetrically distributed on both sides of the wound to be sutured. The spacing "t" should satisfy that the distance between the first patch 1 and the skin edge of one side of the wound and the distance between the second patch 2 and the skin edge of the other side of the wound are both appropriate. The so-called "appropriate" generally means that the first flap 5 and the second flap 6 can symmetrically turn the skin edges on both sides of the wound outward and effectively fit. After adjusting the spacing "t", you can tear off the left release paper base (i.e., the first area 72 of the release paper 7) and the right release paper base (i.e., the third area 74 of the release paper 7), and stick the non-invasive suturing instrument 100 on the wound to be sutured. Finally, the adjusting screw 8 is rotated again to further reduce the distance "T" between the first main seat 3 and the second main seat 4, thereby causing the first connecting rod 9 and the second connecting rod 11 to slide upward along their respective guide grooves, driving the first flap 5 and the second flap 6 to symmetrically evert and close the skin on the wound surface. Because the wound can be everted and closed, compared to existing suture devices on the market that combine flat and pull methods, this embodiment can achieve better wound closing and achieve scar-free results.

[0070] It can be seen that the non-invasive suturing instrument proposed in this embodiment is specifically a closure mechanism used for tension reduction, skin beautification, and skin eversion. Its structure is novel and reasonable, and a wound eversion component is provided to be used in conjunction with the adjustment component. When the adjustment drive drives the first patch and the second patch to approach each other, the flap upward drive of the wound eversion component can simultaneously drive the first flap and the second flap to turn upward, so that the two sides of the wound to be sutured are symmetrically everted, so that the wound tissues on both sides of the wound can better contact and fit together. Moreover, since the wound / wound is everted for fitting, compared with the flat-pull combined suture device on the market, the scar formed by the present invention is smaller and smoother, or even has no obvious scar, and is suitable for non-invasive suturing of surgical incision skin or wound skin in plastic surgery.

[0071] Example 2

[0072] This embodiment provides a method for using the non-invasive suturing device 100 in the first embodiment, which mainly includes the following steps:

[0073] Step 1: Remove the release paper 7 located in the second area 73 along the dividing line 71. The dividing line 71 can be a dotted line (also called a "cliff line") or a solid dividing line.

[0074] Step 2: Adjust the distance between the first patch 1 and the second patch 2 by adjusting the drive so that the first flap 5 and the second flap 6 are at an appropriate distance from the skin edges on both sides of the wound to be sutured. Generally, this step is to rotate the adjusting screw 8 according to the distance between the outer edges of the wound to be sutured to appropriately reduce the distance "T" between the first main seat 3 and the second main seat 4, thereby ensuring that the distance "t" between the first flap 5 and the second flap 6 can meet the wound area to be sutured and the eversion effect of the flap on the skin on both sides of the wound, such as Figure 2 As shown, the first flap 5 and the second flap 6 are respectively arranged at the edge positions of the first patch 1 and the second patch 2, and the spacing "t" between the first flap 5 and the second flap 6 can also represent the distance between the first patch 1 and the second patch 2. Generally, the first patch 1 and the second patch 2 are symmetrically or approximately symmetrically distributed on both sides of the wound to be sutured, and the spacing "t" should satisfy that the distance between the first patch 1 and the skin edge of one side of the wound and the distance between the second patch 2 and the skin edge of the other side of the wound are both appropriate. The so-called "appropriate" generally means that the first flap 5 and the second flap 6 can symmetrically turn the skin edges on both sides of the wound outward and effectively fit.

[0075] Step 3: After adjusting the spacing "t", tear off the release paper 7 in the first area 72 and the release paper 7 in the third area 74, and stick the first patch 1 and the second patch 2 on both sides of the wound to be sutured respectively;

[0076] Step 4: Rotate the adjusting screw 8 again to further reduce the distance "T" between the first main seat 3 and the second main seat 4, so that the first connecting rod 9 and the second connecting rod 11 slide upward along their respective guide grooves, and drive the first flap 5 and the second flap 6 to symmetrically turn outward and close the wound surface skin.

[0077] It can be seen that the method of using the non-invasive suturing instrument proposed in this embodiment is easy to operate. By symmetrically turning the two sides of the wound to be sutured, the wound tissues on both sides of the wound can be better contacted and fitted together, and the scar formed is less visible or even has no obvious scar. It is suitable for non-invasive suturing of surgical incision skin or wound skin in plastic surgery.
