Description

Dermatological clinical wart scraping device and method Technical Field The invention relates to the technical field of wart scraping equipment, in particular to a clinical wart scraping device and method for dermatology. Background In dermatological clinics, curettage of warts (e.g., verruca vulgaris, condyloma acuminatum, etc.) is a common physical treatment. The method typically involves mechanical force to strip wart tissue from its base by means of a curette or the like. The operation core is to thoroughly remove the focus and to protect the surrounding normal skin tissue to the maximum extent so as to reduce the risks of bleeding, postoperative infection and scar formation in the operation. Currently, conventional curettes are widely used clinically for operation, which are ring-shaped semi-sharp knives (e.g., bei Laiwo curettes). The standard procedure is that the operator marks the skin lesion boundary first, then holds the curet, and repeatedly and centripetally scrapes the wart body tissues along different directions by means of personal experience and hand feeling until the macroscopic wart body tissues are completely removed. However, the conventional method has a plurality of inherent defects that the conventional method mainly depends on personal experience and hand feeling of an operator to perform repeated operations, and in the process, stable and sufficient control on the scraping boundary and depth is difficult, and the scraping range is easily deviated from a preset skin damage area or cut too deeply, so that surrounding normal skin tissues are unnecessarily damaged, and the conventional method is a main operation defect that the postoperative recovery quality is affected and the scar formation risk is increased. For this purpose, a device and a method for scraping warts in dermatology clinical are needed to solve the problem. Disclosure of Invention In order to solve the above problems, the present invention provides a device and a method for scraping warts in dermatology, which are used for controlling the scraping movement of the scraping body and the extension of the cutting blade to cooperatively complete the scraping movement and the opposite side cutting movement, thereby reducing the scraping times required for thoroughly removing warts and reducing the normal skin damage caused by repeated operations. In order to achieve the purpose, the technical scheme of the invention is that the clinical wart scraping device for the dermatology comprises a scraping body, wherein the scraping body consists of a holding rod and a scraping rod, the bottom of the scraping rod is symmetrically provided with a scraping body and a positioning cutting piece, the scraping body is annular, a functional cavity is arranged in the lower part of the scraping rod, and a driving component for driving the scraping body to swing to scrape the wart is arranged in the functional cavity; the positioning cutting piece comprises an L-shaped positioning rod, a sliding cavity is arranged in the positioning rod, a first piston is in sliding fit in the sliding cavity, the top of the first piston is fixedly connected with a push rod, the top end of the push rod penetrates through the bottom wall of the functional cavity to extend into the functional cavity and is vertically hinged with a deflector rod, the other end of the deflector rod is hinged with the driving assembly, the bottom of the deflector rod is hinged with a fulcrum rod, the bottom end of the fulcrum rod is fixedly connected with the inner bottom wall of the functional cavity, and the fulcrum rod and the deflector rod form a lever structure; The sliding cavity bottom sliding fit has the second piston, forms airtight chamber between second piston and the first piston, and second piston keeps away from first piston one side fixedly connected with cutting blade, and cutting blade opposite side can pass sliding cavity one side and extend outside the sliding cavity. The technical principle of the scheme is that the scraping body is driven to move towards the wart body in an arc-shaped motion to cut through the driving of the driving component, and meanwhile, the cutting blade is driven to extend out of the sliding cavity to cut the root of the opposite side of the wart body, so that the wart body is scraped and cut rapidly, and the scraping times required when the wart body is scraped are reduced. The adoption of the scheme has the following beneficial effects: 1. According to the scheme, the skin damage edge is attached to the positioning rod to serve as a physical reference, and the extending cutting blade is combined, so that a limit boundary is formed on the opposite side of the scraping body movement path. The scraping body can be effectively prevented from crossing the boundary or being excessively deep, the scraping operation is mainly limited in the range of wart body tissues, the surrounding normal skin structure can be protected, and the probability o
