Description

Stereoscopic line tracing device used before chest operation and using method thereof
Technical Field
The invention relates to the field of medical treatment, in particular to a chest preoperative stereoscopic line tracing device and a using method thereof.
Background
When a radical breast cancer operation is clinically performed, the outline (generally in a fusiform shape) of the skin of a part to be cut is drawn on the surface of a breast in advance, and the size of an incision is drawn according to the clinical experience of a doctor, so that the incision is too large or too small, and the skin tension is too high or wrinkles occur after later-stage suturing;
however, the applicant believes that the main reason for tension or relaxation after postoperative skin suturing is not only a clinical experience problem, but also the fact that in the conventional line drawing state, the patient lies down and the chest is attracted by the earth attraction to become flat, so that the line drawing skin is in a stretched or pressed state in the state, errors exist after the line drawing is finished, and problems are caused after later-stage suturing;
therefore, only in the weightless state, the breast can maintain an optimal shape, and the tension of each part of the surface skin is uniform, but in the actual operation, the breast does not have the condition, so the breast can not be applied to the operation.
Disclosure of Invention
In view of the above problems, the present invention aims to provide a preoperative stereograph for breasts and a method for using the same, which can reduce the phenomenon that the breasts are drawn in a flat state due to gravity collapse and the skin is tensioned or loosened due to late suturing before an operation.
Aiming at the problems, the following technical scheme is provided: a chest preoperative stereoscopic line tracing device comprises a hemispherical shape-fixing cover with an opening at one side, wherein a plurality of line tracing through holes are uniformly distributed on the surface of the shape-fixing cover, and the aperture of each line tracing through hole is between 3mm and 20 mm; the hole wall spacing distance between the adjacent line drawing through holes is 1mm-3 mm; a containing through hole is arranged at the arch top of one end of the shaping cover, which is back to the opening, and the diameter of the containing through hole is between 10mm and 50 mm; an adhesive layer is arranged on the inner wall of the shaping cover between the adjacent line drawing through holes; the thickness of the shaping cover is 0.5mm-3 mm.
In the structure, the shape of the hemispherical shaping cover is matched with the shape of a breast in a gravity-free environment, when the shaping cover covers the breast, a painting brush can penetrate through the drawing line through hole to draw points on the skin of the breast and establish a basic outline of lines, the accommodating through hole is used for accommodating the nipple, so that the breast can be tightly attached to the inner wall of the shaping cover and adhered by the adhesive layer, the situation that the position of the breast close to the nipple cannot be attached to the shaping cover due to the protrusion of the nipple is avoided, and the shape of the breast can be shaped by the shaping cover; the aperture of the line drawing through hole is preferably in four specifications of 3mm, 5mm, 10mm and 15mm, the smaller aperture is suitable for drawing points, and the larger aperture can be used for drawing lines properly; the spacing distance between the hole walls of the adjacent line drawing through holes is preferably 2mm, and the thickness of the shaping cover with the preferred thickness of 1.5mm is matched, so that sufficient strength can be provided for the shaping cover; the diameter of the accommodating through hole is preferably 30mm, and can be changed according to the size of the nipple.
The invention is further provided that a support turning edge integrated with the shaping cover is arranged at the opening of the shaping cover.
In the structure, the support turning edge is used for improving the support area of the opening of the shaping cover and reducing the uncomfortable feeling.
The invention is further provided that the adhesive layer comprises a base layer adhered with the inner wall of the shaping cover and a hydrogel layer attached on the base layer; the line drawing through hole and the accommodating through hole penetrate through the base layer and the hydrogel layer.
In the above structure, the base layer is used to provide an adhesion base for the hydrogel layer; the hydrogel layer is medical hydrogel and has the advantages of good biocompatibility and good skin adhesion, so that the hydrogel layer can adhere to the skin of the breast by utilizing the adhesion characteristic to shape the breast.
