Description

Technical Field

[0001] This utility model relates to a medical device, and more particularly to a device for postoperative shape correction and maintenance after umbilical reconstruction. Background Technology

[0002] A protruding navel can be caused by physiological factors or umbilical hernias. Physiological factors causing a protruding navel, such as obesity leading to an outward protrusion of the navel, or the increased abdominal pressure caused by the enlarged uterus due to the baby's weight gain in late pregnancy, often do not require special treatment and can resolve on their own through physiological changes. However, a protruding navel caused by an umbilical hernia is a relatively common umbilical condition, caused by either congenital or acquired factors. It is divided into infantile and adult umbilical hernias, and presents as a soft bulge or protrusion of the navel. Severe cases can cause intense pain or vomiting, and may even lead to incarceration. Mild cases can be treated with bandages and gauze for fixation, while severe cases may require surgery.

[0003] Surgical treatment involves making a star-shaped incision at the navel, dissecting the skin flap, reshaping the navel deep within, and then fixing it to the rectus abdominis sheath to achieve the desired cosmetic result. Maintaining the navel's shape and exposing the wound post-surgery are crucial to the outcome. Currently, there are no dedicated navel shape correctors on the market, so doctors must use readily available materials such as medical cotton balls and foam earplugs inserted into the navel to maintain its shape. Medical cotton balls do not provide stable shape correction and are prone to dislodgement during recovery; while foam earplugs offer relatively stable shape, they cannot meet patients' specific needs for shape and size. Furthermore, these methods do not reduce tension on the sutured wound, potentially leading to noticeable scarring and affecting aesthetics.

[0004] Chinese utility model patent, authorization announcement number CN217566572U, discloses a postoperative umbilical compression device, including a fixing washer. A bracket is fixedly connected to the upper surface of the fixing washer. The device is configured through the cooperation of the fixing washer, bracket, compression spring, baffle, limiting rod, pressure plate, sponge block, and positioning bolt. In use, the fixing pad is first fixed to the patient's skin to ensure the stability of the fixing washer. Then, the pull ring is pulled by hand to move the limiting rod upward, thereby changing the distance between the sponge block and the patient's umbilical. After determining the distance, the positioning bolt is tightened to keep the sponge block stationary at the umbilical position. Different distances can ensure different pressures are applied to the patient, reducing discomfort and improving the compression effect. However, this device only compresses the umbilical by fixing the cotton ball at the reconstructed umbilical position, only compressing the wound. It cannot achieve a good effect on shaping the reconstructed umbilical. Moreover, the pressure is concentrated in the middle, completely covering the wound, which can easily cause poor wound ventilation after surgery, leading to difficult healing, severe swelling, and tissue necrosis.

[0005] Chinese utility model patent CN220513003 U discloses a postoperative orthotic device for umbilical reconstruction. This orthotic device includes a rigid tube clamped onto the navel, with one end of the tube closed and a drainage hole at the closed end. This patent aims to shape the orthotic device by clamping it inside the navel, preventing scar misalignment and adhesion. The drainage hole facilitates the drainage of postoperative tissue fluid, preventing accumulation between the umbilical cord and the closed end of the tube, which could lead to bacterial infection of the wound. However, the installation method of this orthotic device, like inserting cotton balls, can result in insecure fixation. Furthermore, the orthotic device is cylindrical and rigid, and its shape does not perfectly match the shape of the reconstructed navel, thus compromising the orthotic effect.

[0032] The embodiment provides a device for postoperative shape correction and maintenance after umbilical reconstruction, such as Figures 1 to 8As shown, the device includes a shaping body 1, a base plate 2, a tensioning device 3, and a locking device 4. The shaping body 1 is a hollow, rigid, elastic structure. One end of the shaping body, which is inserted into the navel, has an arc-shaped closed surface, while the other end is open. The cross-section of the shaping body 1 is elliptical or near-elliptical, and the diameter of the shaping body 1 gradually decreases from the closed end to the open end, matching the shape of the reconstructed navel. Multiple slots 5 are provided near the open end of the shaping body 1, arranged equidistantly around the body 1, and 2-3 mm away from the opening, facilitating the cleaning of seepage. Two sets of wing plates 6 are symmetrically arranged on the outer edge of the open end of the shaping body 1. Each set includes two plates, and the wing plates 6 are integrally formed with the shaping body 1 using the same rigid, elastic material. The main purpose of the wing plates 6 is to fix the tensioning device 3. The substrate 2 is symmetrically distributed on both sides of the main body. The substrate 2 is made of a non-toxic, non-allergenic, non-irritating material with good biocompatibility. It is used to adhere to the outside of the wound. A second adhesive layer covering the release film is provided on the side of the substrate 2 away from the locking device 4. When in use, the release film is torn off and then pasted to the intact skin outside the wound.

[0033] The umbilical reconstruction postoperative shape correction and maintenance device in the embodiment, such as Figures 1 to 5 As shown, the tensioning device 3 is provided in two sets. Each set of tensioning device 3 includes two pull rods or pull ropes 300 with toothed grooves. The two pull rods or pull ropes 300 are respectively fixed to the two plates of the corresponding wing plate 6, and the other end extends horizontally in the direction of extension of the corresponding wing plate, as shown. Figure 8 As shown, each pull rod or rope 300 has a pull ring 301 at the end furthest from the shaping body 1. Each set of tensioning devices 3 is equipped with a corresponding set of locking devices 4 for locking the tensioning devices 3. The locking devices 4 are fixed to the base plate 2 by adhesive plates, and the base plate 2 and the wing plate 6 are on the same plane. Figure 7 As shown, the locking device 4 is provided with a latch that matches the toothed groove, and each set of locking devices 4 includes the same number of latches as the pull rod or pull rope 300; the pull rod or pull rope 300 passes through the corresponding locking device 4 and locks with the latch in the toothed groove when it is tightened.

[0034] In this embodiment, the substrate 2 is made of any one of the medical materials selected from PE, PET, PU, ​​or non-woven fabric; the first adhesive layer 7 and the second adhesive layer are both made of hydrocolloid or various medical pressure-sensitive adhesives. The rigid elastic material includes silicone or TPE thermoplastic elastomer, or other thermoplastic elastomers may be used.

[0035] In the embodiments, such as Figures 1 to 3As shown, symmetrical inclined surfaces are provided on both sides of the cylindrical portion at the upper part of the shaping body 1, and a first adhesive layer 7 covering the release film 8 is provided on the inclined surfaces. The release film of the first adhesive layer 7 extends above the opening end of the shaping body 1. This allows the body 1 to be stably bonded to the umbilical tube through the adhesive, maintaining the shape and size of the navel, and providing a stable bonding force when tightened to prevent the body from being pulled out. The release film 8 prevents the outer surface of the adhesive from adhering to other parts, and the release film 8 extends above the opening of the body, making it easy to tear off the release film 8 after the body is embedded in the umbilical tube.

[0036] The main body 1 of this invention is made of an elastic material with a certain degree of hardness, which can be squeezed when inserted into the umbilical canal for easy insertion. The main body 1 has a dome-shaped (bullet-like) structure for easy insertion into the navel, with an internal cavity. The cavity structure facilitates the doctor's pressure operation and can also be filled with cotton swabs or harder materials to absorb exudate flowing from the grooved structure while providing more stable shaping function. The opening surface of the main body 1 is provided with a wing plate 6 fixed to the tensioning device 4, and a groove 5 is provided 2-3mm below the upper end surface of the main body 1 for easy cleaning of exudate. Conical inclined surfaces are provided on both sides of the main body. This structure plays a certain role in spreading and makes the contact with the umbilical canal tighter and more intimate; an adhesive layer is provided on the inclined surface to facilitate fixation with the umbilical canal.

[0037] In use, the main body 1 is embedded into the reconstructed navel. The rebound of the main body 1 maintains the shape of the new navel. Cotton swabs or harder materials can be filled inside as needed to absorb exudate flowing from the grooved structure and provide a more stable shaping function. Then, two substrates 2 are symmetrically adhered to the intact skin on both sides of the wound. The large surface area can disperse the tension generated when tightening, protecting the intact skin. After installation, the tightening device 3 can effectively reduce the tension at the wound suture site and is locked by the locking device 4. The combination of the tightening device 3 and the locking device 4 provides a stable tightening force to help reduce wound tension. By setting the substrates 2, the intact skin adhered to the substrates 2 can move towards the wound as a whole when tightened, and the force is evenly distributed.

[0038] The above description is merely one embodiment of this utility model, and while it is quite specific and detailed, it should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
