Description

Technical Field

[0001] The utility model relates to a scar repair treatment device, in particular to a double-layer plastic hypertrophic scar pressure treatment device. Background Art

[0002] Hypertrophic scars are common diseases in plastic surgery clinics, and the most common causes are burns, trauma, surgery, etc. Scar pressure therapy is a conventional scar treatment method. For hypertrophic scars, local pressure can reduce local blood supply to the scar, causing the scar to gradually soften and shrink. However, there is no obvious difference in the pressure effect of common scar pressure sleeves or pressure garments on normal skin and hypertrophic scars. The pressure is not targeted and can easily cause damage to normal skin. In addition, silicone gel scar patches are the first-line treatment for scars, but they cannot be fixed at the joints. A comprehensive scar pressure treatment device for joints is needed to protect the skin while continuously pressurizing the scar and fix the silicone gel sheet. At present, there are some technologies for the treatment of scars using thermoplastic plates. For example, the Chinese invention patent (application number 202311347176 X) discloses a silicone gel film for preventing and treating scar hyperplasia and a preparation method thereof, including a pressure layer using a low-temperature thermoplastic plate. However, one technical problem that needs to be solved in fixing the molding plate (thermoplastic plate) is that it is difficult to keep the molding plate stably in a fixed position and under a stable pressure by fixing the molding plate with cable ties or bandages. Summary of the invention

[0005] Furthermore, in order to obtain a good scar treatment effect, the inner layer shaping plate 10 corresponds to the shape of the scar site, and the outer layer shaping plate 20 corresponds to the shape of the inner layer shaping plate.

[0006] Furthermore, in order to achieve pressure regulation for scar treatment, the tightening sleeve is provided with a screw hole 32, one end of the tightening sleeve is provided with a positioning column head 33, the outer layer molding plate is provided with a positioning hole 21, the positioning column head 33 passes through the positioning hole 21, and the step surface 34 at the root of the positioning column head is pressed against the outer layer molding plate 20.

[0007] Furthermore, in order to prevent the tightening sleeve from rotating when adjusting the tightening screw, the positioning column head is a multi-corrugated column head, and the positioning hole of the outer plastic plate is a multi-corrugated hole corresponding to the positioning column head.

[0008] Furthermore, a structure for pressing the inner plastic plate is that the tightening screw presses the inner plastic plate.

[0022] Embodiment 1:

[0023] like Figures 1 to 4 A double-layer shaping hypertrophic scar pressure treatment device comprises an inner shaping plate 10 and an outer shaping plate 20.

[0024] The inner layer molding plate 10 corresponds to the shape of the scar area, and commonly used manufacturing methods include thermoplastic plate molding or 3D printing material molding, so that the inner layer molding plate 10 fits well with the body surface of the patient's scar area.

[0025] The outer layer molding plate 20 corresponds to the shape of the inner layer molding plate 10. In this embodiment, the outer layer molding plate 20 adopts the same structure as the inner layer molding plate. Similarly, the outer layer molding plate can also be made by thermoplastic plate molding or 3D printing material molding, that is, making two identical molding plates. The outer layer molding plate is provided with a positioning hole 21, and the position of the positioning hole 21 should correspond to the corresponding scar position during use. The positioning hole 21 adopts a multi-ribbed hole. In this embodiment, the positioning hole 21 adopts a hexagonal hole, that is, an equilateral hexagonal through hole.

[0026] A tightening sleeve 30 is provided between the inner layer plastic plate and the outer layer plastic plate, and the tightening sleeve is provided with a screw hole 32. A positioning column head 33 is provided at one end of the tightening sleeve. The positioning column head 33 is a six-cornered column head corresponding to the positioning hole 21 of the outer layer plastic plate. The positioning column head 33 passes through the positioning hole 21, and the step surface 34 at the root of the positioning column head presses on the outer layer plastic plate 20.

[0027] A tightening screw 31 is arranged in the screw hole of the tightening sleeve, and the tightening screw is used to push the inner plastic plate 10 to move equivalent to the outer plastic plate 20. In this embodiment, the tightening screw 31 passes through the screw hole 32 of the tightening sleeve and directly presses on the inner plastic plate 10.

[0028] The inner and outer molding plates 10 and 20 are tied to the body surface of the scar part by the binding belt 50, and the binding belt 50 is tied outside the outer molding plate. In order to operate the tightening screw 31, the binding belt is provided with an adjustment hole 51 at the position corresponding to the tightening sleeve 30 (i.e., the position of the positioning hole 21).

[0029] Taking the inner and outer molding plates formed by thermoplastic plates as an example, thermoplastic plates are first used to make inner and outer molding plates with the same shape as the surface of the scar area. Usually, the inner and outer molding plates are the same and can be stacked inside and outside. Then the inner molding plate 10 is attached to the scar surface area, and the top tightening sleeve 30 is installed on the outer molding plate 20, so that the positioning column head 33 of the top tightening sleeve passes through the positioning hole 21 of the outer molding plate, and the step surface 34 at the root of the positioning column head presses against the inner side of the outer molding plate 20. Then the outer molding plate 20 is nested on the inner molding plate 10, and the end of the top tightening sleeve 30 presses against the inner molding plate, and then tied to the outside of the outer molding plate with a binding belt 50. The binding belt 50 can be a nylon binding belt or a bandage, and the specific body position is bound in the usual surgical binding method. After the binding is completed, an adjustment hole 51 is opened in the binding belt at the position corresponding to the top tightening sleeve 30 (i.e., the position of the positioning hole 21), such as by using scissors or a scalpel to open the hole. Figure 5 shown.

[0030] Then screw the tightening screw 31 into the screw hole 32 of the tightening sleeve. Figure 6 As shown. Turn the tightening screw 31 to press the inner plastic plate 10 and adjust it to an appropriate pressure state, and at the same time, the inner plastic plate can be stably maintained at the scar site. The use of multi-ribbed positioning studs and positioning holes can prevent the tightening sleeve from rotating when adjusting the tightening screw.

[0031] In this embodiment, a pressing sleeve 30 is provided between the inner molding plate and the outer molding plate, and there is only one pressing point on the inner molding plate. Alternatively, multiple pressing sleeves 30 may be provided according to the specific scar treatment conditions to press the inner molding plate at multiple points to obtain a more effective pressing adjustment function.

[0032] In the drawings of this embodiment, only arc-shaped inner and outer molding plates are schematically shown. In practical applications, inner and outer molding plates of various shapes can be manufactured according to the shape of the scar surface.

[0033] Thanks to the maturity and widespread application of thermoplastic molding technology and 3D printing technology, scar pressure treatment devices can use a pressure plate with the same shape as the scar surface, combined with silicone gel materials, to perform compression treatment on the scar. However, the fixing effect of the pressure plate has a great influence on the treatment effect. The utility model uses a double-layer molding plate, and a tightening screw is used between the double-layer molding plates to press the inner molding plate, which can easily adjust the pressure of the molding plate on the scar and keep the molding plate stably in the treatment position.

[0034] Embodiment 2:

[0035] like Figure 7 , Figure 8, a double-layer plastic hypertrophic scar pressure treatment device. This embodiment is an improvement of the first embodiment.

[0036] In this embodiment, a top tightening washer 40 is provided between the inner mold plate 10 and the outer mold plate 20 , and the top tightening washer 40 is slidably fitted on the top tightening sleeve 30 .

[0037] During installation, the end of the tightening sleeve 30 presses against the tightening gasket 40, and the tightening gasket 40 presses against the inner plastic plate.

[0038] When the inner plastic plate 10 is adjusted, the tightening screw 30 presses the tightening washer 40 , and the tightening washer 40 presses the inner plastic plate 10 .

[0039] This embodiment avoids using the end of the tightening screw to press the inner plastic plate, thereby preventing the inner plastic plate from being damaged by excessive concentrated pressure from the tightening screw.
