[0035] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

[0036] refer to Figure 1 and Figure 2 The present invention discloses a wound closure device 10 for percutaneous puncture surgery, which can simplify the operation of closing radial wounds after percutaneous puncture surgery.

[0037] Combined with Figure 3 and Figure 4 The wound closure device 10 for percutaneous puncture surgery includes a base 100, a transmission assembly 200, and an adhesive member 300. The base 100 is approximately hollow cylindrical and can be molded using flexible medical silicone. It has passed the ISO109935 cytotoxicity test and meets the hypoallergenicity requirement. The transmission assembly 200 is disposed within the base 100 and may include multiple moving members 210 that can move synchronously relative to the base 100. Synchronous motion can be simply understood as: when one moving member 210 is driven to move, another moving member 210 also moves, and there is no time difference or the time difference between the two movements is negligible. The adhesive member 300 is provided in plurality and is fixedly connected to the moving members 210 in a one-to-one correspondence. During use, the adhesive member 300 is attached to the wound area of the percutaneous puncture surgery. The transmission assembly 200 can be driven to cause all moving members 210 to move synchronously toward the center of the wound area to close the wound via the adhesive member 300.

[0038] In some embodiments, the adhesive member 300 may include a plurality of adhesive dressings 310, and a chain 320 and a zipper head 330 are connected between adjacent adhesive dressings 310, and the zipper head 330 is fixedly connected to the movable member 210 in a one-to-one correspondence. In the process where the transmission assembly 200 is driven to drive all movable members 210 to move synchronously toward the center of the wound area, the zipper head 330 closes the adjacent adhesive dressings 310. Exemplarily, the adhesive dressing 310 can be a band-aid, which can contain a chitosan antibacterial layer to prevent infection and accelerate wound healing. In other embodiments, depending on the type of wound, the adhesive dressing 310 can contain different symptomatic drugs to prevent infection and accelerate wound healing. Exemplarily, the surface of the zipper head 330 can be provided with a chitosan antibacterial layer (antibacterial rate ≥ 99%, ISO20743) to prevent wound infection.

[0039] For example, in Figure 3In the illustrated embodiment, a three-flap adhesive bandage is used, with three movable members 210 synchronously driving three zipper pulls 330 to move in three directions, thereby tightening the radial wound. It is understood that for radial wounds of other shapes, the adhesive dressing 310 and movable members 210 can be adaptively adjusted. For example, if the adhesive dressing 310 is a four-flap adhesive bandage, four movable members 210 can be used to synchronously drive four zipper pulls 330.

[0040] Furthermore, in some embodiments, the surface of the base 100 facing the skin or the lower surface of the base 100 can be laminated with a pressure-sensitive adhesive 1131 and a protective film 1132, and the protective film 1132 is located on the outside of the pressure-sensitive adhesive 1131. The protective film 1132 can isolate dust, microorganisms, body fluids, etc., to prevent the pressure-sensitive adhesive 1131 from failing prematurely. During use, first clean the wound with sterile saline or other suitable disinfectant to remove impurities such as blood and tissue fragments, then tear off the protective film 1132, and stick the base 100 on the skin around the wound through the pressure-sensitive adhesive 1131, and then use the moving part 210 to synchronously drive the corresponding zipper head 330 to move and aggregate to tighten the radial wound, thereby achieving closure of the wound. After the skin heals, the base 100 can be directly torn off along the skin surface, thereby avoiding secondary damage to the skin caused by the traditional suture removal operation. Exemplarily, the peel strength of the pressure-sensitive adhesive 1131 is ≤0.08N / cm, which can more effectively avoid tissue damage during the tearing process.

[0041] The above-mentioned wound closure device 10 for percutaneous puncture surgery includes a base 100, a transmission assembly 200, and an adhesive member 300. The transmission assembly 200 is disposed on the base 100 and includes a plurality of movable members 210 capable of synchronous movement relative to the base 100. The adhesive members 300 are provided in a plurality and fixedly connected to the movable members 210 in a one-to-one correspondence. The adhesive members 300 can be attached to the wound area of the percutaneous puncture surgery. The operator then drives all movable members 210 to synchronously move toward the center of the wound area through the transmission assembly 200, thereby closing the wound via the adhesive members 300. After the wound heals, the base 100 can be torn off from the skin surface. This device can accurately and effectively close radial wounds after percutaneous puncture surgery without relying on complex traditional suturing techniques, thereby greatly simplifying the operation process and improving work efficiency. The wound closure device 10 for percutaneous puncture surgery of the present invention can not only reduce the cost of suturing and removing sutures, but also reduce the risk of infection because it does not require traditional suturing and removing sutures, which are harmful to the skin.

[0042] Combine Figure 5The base 100 may include an outer cylinder 110 and an inner cylinder 120. The outer cylinder 110 is provided with an inner cavity 1121 to accommodate the inner cylinder 120. The outer cylinder 110 is approximately cylindrical with one end closed and the other open. A pressure-sensitive adhesive 1131 and a protective film 1132 are provided at the edge of the open end of the outer cylinder 110. The inner cylinder 120 is approximately cylindrical with both ends open. The outer cylinder 110 and the inner cylinder 120 can be made of the same material, for example, flexible medical silicone. During the assembly of the wound closure device 10 for percutaneous puncture surgery, since the inner and outer cylinders 120, 110 are made of flexible medical silicone, the transmission assembly 200 can be assembled with the inner and outer cylinders 120, 110 while the inner and outer cylinders 120, 110 are deformed, thereby reducing molding and assembly precision requirements. Flexible medical silicone also has relatively good biocompatibility, which can reduce discomfort caused by bumps on the skin during use and improve user comfort. In other words, the above design can not only improve the convenience of assembly and reduce production costs, but also improve the comfort of use.

[0043] Further, combined Figure 3 The outer cylinder 110 may include an integrally formed cover 111, a sidewall 112, and an outer ring 113. The cover 111 covers one end of the cylindrical sidewall 112, and the outer ring 113 is connected to the other end of the sidewall 112 and protrudes from the outside of the sidewall 112. A pressure-sensitive adhesive 1131 and a protective film 1132 extend along the surface of the outer ring 113 facing away from the cover 111. The cover 111 and the sidewall 112 form an inner cavity 1121 for accommodating the transmission assembly 200 and the inner cylinder 120. The diameter of the inner cavity 1121 is comparable to the outer diameter of the inner cylinder 120, so that the inner cylinder 120 and the outer cylinder 110 can form a transition fit or a tight fit, facilitating the assembly of the inner cylinder 120 into the outer cylinder 110 and preventing the two from easily loosening.

[0044] refer to Figure 4 In the circumferential direction of the outer ring 113, a plurality of through holes 1122 may be provided at intervals at the connection between the side wall 112 and the outer ring 113. The through holes 1122 correspond one-to-one to the moving member 210 and can be used to accommodate one end of the moving member 210, so that one end of the moving member 210 can be supported and confined within the through hole 1122, preventing the moving member 210 from easily falling out of the inner cylinder 120. The surface of the outer ring 113 on the same side as the cover 111 may be recessed and provided with a receiving groove 1133 corresponding one-to-one to the through hole 1122. After the moving member 210 is inserted into the through hole 1122, the bottom and wall of the receiving groove 1133 can limit and guide the movement of the moving member 210, preventing the movement of the moving member 210 from being deflected.

[0045] Recombination Figure 5In some embodiments, the end of the inner tube 120, away from the cover portion 111 of the outer tube 110, may be provided with a plurality of spaced apart limiting slots 121. These limiting slots 121 correspond one-to-one with and are connected to the through-holes 1122 of the outer tube 110. The limiting slots 121 can be used to accommodate and constrain the movable member 210, preventing the movable member 210 from significantly deflecting during movement. The limiting slots 121 on the inner tube 120 correspond to the movable member 210 and also to the zipper pull 330 of the adhesive member 300. For example, using a three-petal adhesive bandage as an example, the three limiting slots 121 are evenly spaced along the circumference of the inner tube 120 at one end of the inner tube 120, with the central angle between adjacent limiting slots 121 being 120 degrees. The three movable members 210 synchronously drive the three zipper pulls 330 to move in three directions, thereby tightening the radial wound through the adhesive dressing 310.

[0046] In some embodiments, the shapes of the outer cylinder 110 and the inner cylinder 120 may vary. For example, the outer cylinder 110 and the inner cylinder 120 may be prism-shaped, such as a hollow rectangular box or a hollow triangular prism, which will not be described in detail here.

[0047] refer to Figure 6 and Figure 7 In some embodiments, the transmission assembly 200 disposed within the inner cylinder 120 includes a driving wheel 220 and a driven member 230. A plurality of driven members 230 are provided and are respectively linked to the driving wheel 220. Each driven member 230 is linked to a movable member 210 in a one-to-one correspondence. The driving wheel 220 is driven to rotate relative to the base 100, thereby driving all driven members 230 to move synchronously on the base 100. Each driven member 230 drives the corresponding movable member 210 to move.

[0048] In some embodiments, the driving wheel 220 may be a spur gear, and the driven member 230 meshes with the driving wheel 220 for transmission. In an embodiment where the adhesive member 300 is a three-petal bandage, three driven members 230 are provided, and all driven members 230 are evenly spaced around the circumference of the driving wheel 220, i.e., the central angle between any two adjacent driven members 230 is 120 degrees. All driven members 230 are meshed with the driving wheel 220, and the driven members 230 are meshed with the moving member 210 for transmission. This method can achieve uniform force on the three moving members 210, thereby evenly tightening the skin at the wound site and preventing excessive force on the local skin at the wound site from causing discomfort.

[0049] Combined with Figure 8 The transmission assembly 200 may include a plurality of guide rods 240 disposed on the inner cylinder 120, and the guide rods 240 and the driven members 230 are slidably matched one by one. The guide rods 240 may be straight and pass through the driven members 230 so that the driven members 230 can slide along the guide rods 240 in a straight line. Figure 3In some embodiments, the base 100 may be provided with a through-hole 130 extending from the outer surface of the outer cylinder 110 to the inner surface of the inner cylinder 120. Opposite ends of the guide rod 240 are respectively passed through the through-hole 130 and restrained in the base 100. In other words, in this embodiment, after the follower 230, the driving wheel 220, and the moving member 210 are initially restrained in the inner cylinder 120, the guide rod 240 can be passed from one side of the outer cylinder 110 through the through-hole 130 and the corresponding follower 230 and restrained in the through-hole 130 on the other side of the outer cylinder 110. This ensures that the follower 230 is reliably restrained in the inner cylinder 120, thereby improving assembly efficiency. In particular, in some embodiments, the extension direction of any guide rod 240 is perpendicular to the movement direction of the corresponding movable member 210, and the rotation axis of the driving member 213 is perpendicular to the extension direction of each guide rod 240, thereby constraining and limiting the movement direction of the driven member 230, and preventing transmission failure when the driven member 230 interacts with the driving wheel 220 and the movable member 210.

[0050] In some embodiments, the follower 230 and the moving member 210 can be driven by helical gears. For example, the follower 230 includes first helical teeth 231, and the moving member 210 includes second helical teeth 211 that mate with the first helical teeth 231. When the follower 230 is driven by the drive wheel 220 to move along the guide rod 240, the first helical teeth 231 engage with the second helical teeth 211, driving the moving member 210 along the through hole 1122 and the limiting slot 121. This in turn causes the zipper head 330 to move toward the center of the drive wheel 220, pulling the adhesive member 300 to close the radial wound. The first and second helical teeth 231, 211, are relatively easy to manufacture, simplifying the transmission structure and reducing production costs.

[0051] Further reference Figure 3 The central area of the cover 111 may be provided with a connection hole 1111. The transmission assembly 200 may include a screw 250 passing through the connection hole 1111. The screw 250 is fixedly connected to the drive wheel 220 and protrudes from the outside of the base 100. During use, after the base 100, with the protective film 1132 removed, is placed on the skin around the wound, the screw 250 is rotated to drive the drive wheel 220 to rotate. The drive wheel 220 drives all the driven parts 230 to move synchronously. All the moving parts 210 can then synchronously drive the corresponding zipper heads 330 to move and aggregate, tightening the radial wound, thereby closing the wound.

[0052] Furthermore, the connecting hole 1111 has internal threads. The screw rod 250 may include an integrally formed threaded rod 251 and a rod cap 252. The rod cap 252 protrudes from the outer barrel 110, and the width of the rod cap 252 is greater than the width of the threaded rod 251. The threaded rod 251 is threadedly engaged with the connecting hole 1111 and is fixedly connected to the drive wheel 220. The rod cap 252 may be circumferentially arranged with anti-slip teeth 2521 to increase friction during use, making it easier for the operator to use the wound closure device 10 for percutaneous puncture surgery.

[0053] In some embodiments, the gap between the base 100 and the threaded rod 251 is ≤0.05 mm, and the hole wall of the connecting hole 1111 can be coated with a waterproof coating to prevent liquid from penetrating, inhibit the growth of microorganisms in the gap, and reduce the risk of postoperative infection.

[0054] In other embodiments, the screw 250 used to drive the drive wheel 220 can be replaced with another component, such as a flat-head screwdriver or a Phillips screwdriver, as long as the drive wheel 220 has a tool slot that matches the shape of the screwdriver. When needed, the screwdriver is inserted into the connection hole 1111 and the drive wheel 220 is driven to rotate. After the wound is closed, the screwdriver or other tool is removed from the connection hole 1111 and the connection hole 1111 is sealed to prevent the protruding screw 250 or screwdriver from interfering with the patient's movements and to prevent liquid from seeping in.

[0055] refer to Figure 6 、 Figure 7 and Figure 8 In some embodiments, the movable member 210 may have a supporting portion 212, which is located at one end of the movable member 210 near the driving wheel 220. The side of the supporting portion 212 facing away from the driving wheel 220 is fixedly connected to the adhesive member 300, and the side of the supporting portion 212 facing the driving wheel 220 is stepped, that is, there is a height difference between the tooth end of the second bevel tooth 211 of the movable member 210 and the supporting portion 212. In the process of all movable members 210 moving synchronously toward the center of the wound area, since the screw 250 is threadedly connected to the outer cylinder 110, the driving wheel 220 can follow the screw 250 to move toward the adhesive member 300, so as to press the supporting portion 212 through the driving wheel 220, and maintain the pressing effect on the supporting portion 212 through the threaded engagement of the screw 250 and the connecting hole 1111, and then squeeze the wound through the adhesive member 300, thereby achieving accurate alignment of deep tissue and promoting healing.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described.
