Abstract
A retractor device for breast reconstruction surgery which entails the effective exposure and visibility of the breast pocket and, at the same time, does not compromise the integrity of the subcutaneous flap, resulting in a positive outcome of the breast reconstruction procedure generally, but not exclusively, performed using a prepectoral (or sub-cutaneous) acellular biological matrix.
Claims6
A retractor device (9) for breast reconstruction surgery, comprising:
- at least one handle (3) with longitudinal development between an upper end (1.1) and a lower end (3.1) and at least one offshoot (8), the at least one offshoot (8) having a free end (6) and an opposite end (4);
- wherein the at least one offshoot (8) is configured to be placed inside a breast pocket and to lift the skin to expose the interior of the breast;
- wherein the retractor device (9) is formed as a continuous structure extending from the upper end (1.1) to the free end (6),
- wherein the continuous structure includes a first continuous surface and a second continuous surface that faces an opposite direction relative to the first continuous surface, said first continuous surface being formed by at least three distinct sections (s1, s2, s3) joined seamlessly, wherein the at least three distinct sections (s1, s2, s3) comprise a first section (s1), a second section (s2), and a third section (s3);
- wherein the first section (s1) of the first continuous surface consists of the at least one offshoot (8) and takes the form of a convex figure from the free end (6) to the opposite end (4) of the at least one offshoot (8);
- wherein the second section (s2) of the continuous surface is positioned between the at least one offshoot (8) and the at least one handle (3) and takes the form of a concave figure between the opposite end (4) of the at least one offshoot (8) and the lower end (3.1) of the at least one handle (3);
- and
- wherein the third section (s3) of the first continuous surface consists of the at least one handle (3) and takes the form of a concave figure between the lower end (3.1) and the upper end (1.1) of the at least one handle (3).

A retractor device (9) for breast reconstruction surgery comprising:
- at least one handle (3) with longitudinal development between an upper end (1.1) and a lower end (3.1), and
- at least one offshoot (8), the at least one offshoot (8) having a free end (6) and an opposite end (4),
- wherein the at least one offshoot (8) is configured to be placed inside a breast pocket and to lift the skin to expose the interior of the breast;
- wherein said retractor device (9) is formed as a pair of continuous surfaces, each of said continuous surfaces extending from the upper end (1.1) to the free end (6);
- wherein each of the continuous surfaces includes a first continuous surface and a second continuous surface that faces an opposite direction relative to the first continuous surface, said first continuous surface being formed by at least three distinct sections (s1, s2, s3, s1′, s2′, s3′) joined seamlessly, wherein each of the at least three distinct sections (s1, s2, s3, s1′, s2′, s3′) comprise a first section (s1, s1′), a second section (s2, s2′) and a third section (s3, s3′);
- wherein each first section (s1, s1′) of the first continuous surface consists of one offshoot (8a, 8b) of said at least one offshoot and takes the form of a convex figure from the free end (6) to the opposite end (4) of the at least one offshoot (8), wherein each third section (s3, s3′) of the continuous surface consists of one handle (3a, 3b) of said at least one handle, wherein each second section (s2, s2′) of the first continuous surface is positioned between each offshoot (8a, 8b) and each handle (3a, 3b);
- and
- wherein the pair of continuous surfaces is joined together by means of a joint element (10) configured for allowing the offshoots (8a, 8b) to close and open due to the corresponding handles (3a, 3b) opening and closing respectively.
