[0002] Sunken scar is a kind of common skin scar, it is usually due to the defect of dermis and subcutaneous tissue, this defect can be caused by acne, trauma, surgery, infection etc., sunken scar is significantly lower than the surrounding normal skin, and it brings certain trouble to patient.

[0003] The existing sunken scar repair operation is usually performed by medical staff with disposable straight bevel needle or small needle knife, which is inserted into the sunken scar to release the dermal tissue. Since the needle and small needle knife are straight, on the one hand, the needle operation and control are very inconvenient, on the other hand, the sharp needle and the square section of the small needle knife head have the risk of damaging the surrounding blood vessels and nerves during operation. In order to facilitate operation, the medical staff usually need to manually bend the needle, but the effect is limited. In addition, due to the sharpness of the needle, the contact area with the dermal tissue is small, and the release efficiency is low. Therefore, the applicant designs a release instrument for sunken scar repair to solve the above problems. SUMMARY

[0011] Preferably, the cutter head section has a flat, pointed structure, and the cutter head section is composed of a prismatic cutter head or a leaf-shaped cutter head.

[0012] Beneficial effects

[0013] This invention provides a release instrument for repairing depressed scars. Compared with the prior art, it has the following advantages:

[0014] This release instrument for repairing depressed scars features a pre-installed, one-piece, continuously curved separation blade at one end of the handle, making it easy for medical personnel to operate. Furthermore, the flat, pointed blade section, compared to a small needle knife, has smoother edges, reducing the risk of damaging blood vessels and nerves. Additionally, the large contact area between the blade section and the dermal tissue effectively improves the release efficiency. Attached Figure Description

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0029] Please refer to Figures 1-6 The present application provides a technical solution: a loosening instrument for repairing sunken scars, which comprises a handle 100 in a rod structure and a separation knife 200 in a continuous bending structure assembled at one end of the handle 100. The separation knife 200 comprises an assembly section 210 and a blade head section 220, which are parallelly distributed above and below and are both distributed along the length direction of the handle 100, and a bending section 230 connected between the two. The bending section 230 is integrally formed with the assembly section 210 and the blade head section 220 and is arranged at an obtuse angle with both of them. The blade head section 220 is in a flat tip structure.

[0030] Based on the above structure, the loosening instrument for repairing sunken scars is composed of the handle 100 and the separation knife 200. The handle 100 provides an assembly support structure for the separation knife 200 and is held by medical staff to control the separation knife 200. The separation knife 200 is composed of the assembly section 210, the bending section 230 and the blade head section 220, which are connected in sequence from top to bottom and are integrally formed. The blade head section 220 is in a flat tip structure and is connected with the assembly section 210 through the bending section 230. Specifically, in the use process, the medical staff holds the handle 100 and can control the action of the tip structure of the blade head section 220. The medical staff can control the blade head section 220 to be inserted into the sunken scar in a direction parallel to the scar plane and to loosen the dermal tissue by means of the flat structure. The loosening instrument for repairing sunken scars is provided with the separation knife 200 in a continuous bending structure integrally formed at one end of the handle 100, which is easy to control by medical staff. In addition, the blade head section 220 is in a flat tip structure, the edge of which is smooth compared with a small needle knife, which reduces the risk of damaging blood vessels and nerves. Furthermore, the contact area between the blade head section 220 and the dermal tissue is large, which effectively improves the loosening efficiency.

[0031] Further, the top and bottom of the assembly section 210 are provided with flat grooves 2110 and form a plug rod structure 2120, and one end of the handle 100 is provided with a mounting hole 110 for inserting the plug rod structure 2120. Among them, the assembly section 210 provides an assembly structure for the entire separation knife 200, and the mutually matched plug rod structure 2120 and the mounting hole 110 help the positioning and installation of the separation knife 200 at one end of the handle 100. In addition, the two flat grooves 2110 symmetrically distributed can limit the installation of the separation knife 200 during assembly.

[0032] Further, it also includes a rib 240 arranged below between the assembly section 210 and the bending section 230. Among them, the continuously bent separation knife 200 is integrally formed, and the rib 240 arranged below between the assembly section 210 and the bending section 230 provides structural support for the molding of the separation knife 200.

[0033] Further, the top and bottom of the handle 100 near the mounting hole 110 are provided with cut surfaces 120, and the two cut surfaces 120 are pressed with anti-skid lines 130. Among them, the handle 100 is provided with two cut surfaces 120 symmetrically distributed about the axis of the handle 100, and the two cut surfaces 120 facilitate the pressing of the finger part when the medical staff holds and operates.

[0034] Further, a plurality of annular grooves 140 are arranged on the outer wall of the handle 100, and a plurality of annular grooves 140 are evenly distributed along the axis of the handle 100 and are sleeved with silica gel rings 150. Among them, the silica gel rings 150 are evenly distributed on the outer wall of the handle 100, which increases the anti-skid property of the handle 100 and increases the friction force of the medical staff holding the handle 100.

[0035] Further, the knife head section 220 is composed of a prismatic knife head 2210 or a leaf-shaped knife head 2220. Among them, the knife head section 220 is either a prismatic knife head 2210 or a leaf-shaped knife head 2220, both of which are flat and pointed.
