Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a nail-protecting embedding dressing for post-nail avulsion surgery in cases of paronychia. Background Technology

[0002] Nail avulsion is a routine treatment for paronychia. Its purpose is to completely remove the infected portion of the nail, clear the lesion, and prevent the condition from worsening or recurring. The surgery is usually performed under local anesthesia, where the affected nail and inflamed, purulent tissue are cut and removed. Because a large portion of the nail bed is exposed after nail avulsion and the wound is located in a physiologically active area, postoperative care and dressing changes are extremely important.

[0003] Currently, in existing techniques, after nail avulsion surgery, medical staff generally clean the wound with disinfectant, then apply antibiotics to the surgical wound, and finally cover the wound with sterile cotton soaked in the treatment medication. Then, sterile gauze is used to wrap the toe layer by layer to complete the bandage. When changing the dressing, the sterile gauze roll is removed, and then the wound is cleaned, the dressing is changed, and it is bandaged again.

[0004] Currently, the existing technique of using gauze and sterile cotton for pressure bandaging is relatively complicated. Furthermore, this method can easily cause the flesh around the nail bed to be squeezed towards the center, causing the flesh near the nail bed to approach the nail again. Without protection, the nail can easily grow into the flesh at the edge of the nail bed, leading to secondary embedding, inflammation, and worsening. In addition, if the dressing is too thin, it does not adequately protect the wound and nail bed; if the dressing is too thick, it can cause excessive compression and ischemia of the nail bed. Summary of the Invention

[0005] In view of this, the purpose of this invention is to propose a post-operative care dressing for paronychia, specifically a nail embedding prevention dressing. This dressing combines a personalized nail embedding prevention sleeve, a medicated nail bed protective cover, and an elastic mesh shrink-fitting sleeve. This addresses the problem in existing technologies where the lack of a structure that can both fit the patient's surgical toe and flexibly separate the nail groove and nail leads to secondary inflammation and worsening during the recovery process of pressure bandaging. It also solves the problem of existing technologies lacking a protective mechanism that can simultaneously hold the dressing medication within an added medicated cover and a rigid outer shell, resulting in inconvenient dressing changes and insufficient nail bed protection, leading to complicated dressing changes and easy injury to the nail bed during the recovery phase.

[0006] This invention is achieved through the following technical solution:

[0007] A post-operative care dressing for paronychia and nail avulsion includes a personalized toe protective sleeve. The personalized toe protective sleeve has an extension groove at its upper end. The personalized toe protective sleeve consists of a toe area and a toe shaft area. A nail bed protective cover is rotatably installed at the upper end of the toe area. A dressing net is installed at the bottom of the nail bed protective cover. Anti-nail embedding partitions are fixedly installed on both sides of the toe area.

[0008] Furthermore, the personalized toe protector is designed by scanning and modeling the patient's toes and manufactured using 3DP printing technology. The inner side of the personalized toe protector fits the surface of the patient's toe after nail removal.

[0009] Furthermore, the front end of the toe area is a toe tip protective head, and the two sides of the toe area are nail side tissue protective plates, with the nail-protecting embedded partition fixedly disposed on the side of the nail side tissue protective plate.

[0010] Furthermore, an elastic fixing mesh clip is fixedly installed on the top of the toe protection head, and the elastic fixing mesh clip is connected to an elastic fixing mesh for elastic contraction to assist in fixing the personalized toe protection sleeve to the patient's toes.

[0011] Furthermore, the nail bed protective plate includes a left protective plate and a right protective plate. A rotating shaft is fixedly installed at the upper end of the right protective plate, and the nail bed protective cover is rotatably installed on the rotating shaft. A locking buckle is fixedly installed at the bottom left side of the nail bed protective cover, and a locking groove is opened at the upper end of the left protective plate. The locking buckle and the locking groove cooperate with each other.

[0012] Furthermore, the lower end face of the nail bed protective cover is provided with a Velcro hook surface, and the dressing net includes a net textured frame and a net body.

[0013] Furthermore, the bottom surface of the personalized toe protector is a toe support surface, and the toe support surface has breathable and sweat-proof micropores.

[0014] Furthermore, the inner side of the personalized toe protector is fixed with a sterile cotton layer.

[0015] The beneficial effects of this invention are as follows:

[0016] This invention provides a post-nail avulsion dressing that integrates a personalized anti-nail embedding sleeve, a medicated nail bed protective cover, and an elastic mesh shrink-fit fixation sleeve. The personalized toe protective sleeve, combined with the anti-nail embedding partition, effectively separates the nail groove, nail bed, and newly grown nail, preventing secondary nail growth into the nail groove. The nail bed protective cover, combined with an adhesive mesh, holds the dressing to protect the nail bed and surgical site, pressing and adhering the dressing to the nail bed in one go. This protects the nail bed, facilitates dressing changes, and ensures effective medication application. The elastic mesh shrink-fit sleeve presses the personalized toe protective sleeve firmly onto the toe, ensuring the overall stability of the dressing. Attached Figure Description

[0032] like Figure 1-8As shown, one embodiment of the present invention provides a post-operative care dressing for paronychia with nail avulsion, comprising a personalized toe protective sleeve 1. The personalized toe protective sleeve is created by scanning the toes of a patient undergoing nail avulsion for paronychia, modeling the resulting toe, and customizing the target model according to the specific structural requirements of post-operative care. Finally, the personalized toe protective sleeve is manufactured using 3DP printing technology, ensuring the inner side of the sleeve adheres to the surface of the patient's avulsed toe. An extension groove 2 is provided at the upper end of the personalized toe protective sleeve. The personalized toe protective sleeve consists of a toe tip area 3 and a toe shaft area 4. The front end of the toe tip area is a toe tip protective head 5, and on both sides of the toe tip area are nail side tissue protection plates 6. A nail embedding partition 7 is fixedly installed on the side of the nail side tissue protection plates. The nail embedding partition is used to separate the flesh on the side of the nail bed from the nail bed. The nail embedding partition is an arc-shaped plate, and its edge matches the concave part of the patient's nail groove to achieve [the desired effect]. The nail guard is fully embedded in the nail groove. An adhesive layer 8 is provided on the surface of the nail guard, and a nail groove dressing cotton pad 9 is adhered to the surface of the adhesive layer. The nail side tissue protection plate includes a left protection plate 10 and a right protection plate 11. A rotating shaft 12 is fixedly provided at the upper end of the right protection plate, and a nail bed protection cover 13 is rotatably mounted on the rotating shaft. A locking buckle 14 is fixedly provided at the bottom left side of the nail bed protection cover, and a locking groove 15 is provided at the upper end of the left protection plate. The locking buckle and the locking groove cooperate with each other. Furthermore, the personalized toe protector is fixedly connected via magnetic attraction or elastic clips. The lower end of the nail bed protector is equipped with a Velcro hook surface 16. A dressing net 17 is attached to the bottom of the nail bed protector via adhesive. The dressing net includes a net frame 18 and a net body 19. The bottom surface of the personalized toe protector is a toe support surface 20, with breathable and sweat-proof micropores 21 to prevent the soles of the toes from becoming damp and sweaty due to prolonged wear, which can lead to bacterial infection of the wound. An elastic fixing clip 22 is fixedly installed at the top of the toe protector head, and this clip is connected to an elastic fixing net 23 for elastic contraction to further secure the personalized toe protector to the patient's toes.

[0033] In this embodiment, the patient's toes are first disinfected after surgery. Then, the personalized toe protector is slipped over the entire toe from the top of the toe, with the extension groove positioned on the back of the toe. As the toe passes through the toe shaft and enters the toe tip area, the nail-protecting insert plate, with the nail groove dressing cotton pad already attached to the adhesive layer, is slowly squeezed into the nail groove until the toe tip contacts the inside of the toe-protecting head. Then, the anti-inflammatory and disinfected dressing is layered and stuffed into the mesh body. The outer edge of the mesh body is then attached to the large Velcro hook at the bottom of the nail bed protector for fastening. The nail bed protector is then rotated around the rotating axis to bring the dressing mesh closer to the postoperative nail bed until the two are fully compressed and in contact. Finally, the locking buckle is engaged in the locking groove for fixation. Then, the elastic fixing mesh at the elastic fixing clip is pulled out to cover and wrap the entire personalized toe protector, ensuring it fits snugly against the toe.

[0034] When dressing changes are needed, simply pull open the elastic retaining net and the locking structure between the clips and the locking grooves. Then, flip the nail bed protector cover over to remove the dressing pouch, replace the dressing inside, and then flip it over to secure it. To replace the nail groove dressing pad, remove the entire personalized toe protector and then replace the nail groove dressing pad. Because the personalized toe protector is manufactured using 3DP printing technology in a single piece, it is extremely convenient, and the dressing fixation points all use simple adhesive fastening, greatly improving the convenience of dressing changes.

[0035] This embodiment features a post-nail avulsion dressing that combines a personalized anti-nail embedding sleeve, a medicated nail bed protective cover, and an elastic mesh shrink-fit fixation sleeve. The personalized toe protective sleeve, combined with the anti-nail embedding partition, effectively separates the nail groove, nail bed, and newly grown nail, preventing secondary nail growth into the nail groove. The nail bed protective cover, combined with an adhesive mesh, holds the dressing to protect the nail bed and surgical site, pressing and adhering the dressing to the nail bed in one go. This protects the nail bed, facilitates dressing changes, and ensures effective medication application. The elastic mesh shrink-fit sleeve presses the personalized toe protective sleeve firmly onto the toe, ensuring the overall stability of the dressing.

[0036] In this embodiment, the inner side of the personalized toe protector is fixed with a sterile cotton layer, which is beneficial for absorbing sweat and removing medicine squeezed out from the wound when worn for a long time.

[0037] In this embodiment, the personalized toe protector is made of a thin polymer material, which helps to ensure that the personalized toe protector has a certain rigidity for toe protection while also having a certain elasticity for easy wearing and a secure fit.

[0038] In this embodiment, the edges of the personalized toe protectors are rounded to prevent sharp edges from cutting the toes and to avoid discomfort caused by the hard edges.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. 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 be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
