Description

“DEVICE FOR BREAST PROSTHESIS IMPLANT”

The present invention relates to a device for the implantation of breast prosthesis for human use, dispensing the manual contact for its inclusion, presented in syringe format, consisting of three parts, body, valve and plunger, to be actuated. by continuous compression, to be made of material that allows sterilization.

The device allows the introduction of the breast implant directly into the patient with minimal incision in a short period of time. In addition, it eliminates the surgeon's effort to introduce the prosthesis, thus preserving the edges of the incision and reducing the trauma caused at the edges, considerably favoring the quality of the scar, as well as reducing the postoperative time.

Currently breast augmentation is performed due to reconstruction due to mastectomy or hypomastia, in which the breast tissue is displaced, creating a space below the mammary gland, where the prosthesis is placed.

There are three types of incisions for prosthesis inclusion.

mammary:

- Periareolar route: in some patients the resulting scar may be visible around the lower half of the areola; in this case there is

limitations for including the prosthesis according to the patient's areola size;

- axillary route: the scar is almost invisible, being made in the axillary grooves where the prosthesis is usually placed under the pectoral muscle;

The placement of the prosthesis presents greater difficulty, requiring the use of endoscopy for better visualization of the structures; its disadvantages are the increased risk of bleeding and asymmetrical positioning of the prostheses, and there may be cases of temporary decreased sensitivity of the inner face of the arms with this technique;

- inframammary route: applicable in most cases where the

scar will be disguised in the groove of the breast; In this type of incision, the introduction of the prosthesis must be done manually; the incision will be disguised in the groove below the breasts and the risks of bleeding and decreased sensitivity of the areola and nipple are minimal, as is the possibility of infections; It is the accepted route of access for 90% of plastic surgeons because of its advantages.

Surgical procedures follow a pattern in which the

breasts are incised according to previous programming, dissecting a space for the inclusion of prostheses. Technically, this space may be: retroglandular (behind the gland) or retromuscular (behind the pectoralis major muscle). The prosthesis is positioned and covered by the breast tissue, which is then sutured.

The material used in the manufacture of breast implants is a proven biocompatible synthetic polymer known as silicone. This product is part of the prosthesis coating composition and may also be covered by other products such as polyurethane. Already the content of the prosthesis may be silicone (currently gelatinous and cohesive), saline or even some types of oils. Under these conditions, silicone is presented as an inert and highly safe product because, due to its cohesive consistency, if there is a traumatic rupture of the prosthesis, the silicone gel will not disperse, impregnating the 20 tissues. The shapes and sizes of prosthesis are varied.

Currently, surgeries are performed with the aid of appropriate instruments, such as retractors or optical fibers.

MU8601499-4 - refers to an autostatic circular or elliptical surgical retractor for the abdominal wall consisting of a malleable metal bar 25 in the form of a circle or discontinuous ellipse in which polypropylene tubes are placed and these are affixed to bars. metal cylindrical shafts that form the handles away from the edges of the surgical wound. It is a single-function surgical retractor / separator, unlike the present invention, which combines both silicone retractor and introducer functions.

PI9903909-5 refers to a surgical retractor device for minilaparotomy surgeries consisting of support disc and retractor set, maintaining the incision in the open abdominal cavity, allowing physician access to the abdominal cavity, and allowing variation of the incision opening both before as during the surgery by the doctor himself. It differs from the patent filed herein, which combines both silicone retractor and introducer functions.

The main advantages of the device presented here are: the combined functions in the same silicone retractor and introducer equipment; decrease in the size of the incision and consequently a smaller scar; decreased trauma to the edges of the incision and consequently a better scar quality; considerable decrease in operative time.

According to figures 1 to 4 and 9 to 12, the device (1) is composed of removable interconnected body (2), thrust valve (3) and piston (4); the body (2) is subdivided into toecap (2.2) and central module

(2.1) responsible for housing the push valve (3) with indentations (3.2) and central holes (3.1) for piston passage (4). The silicone prosthesis (not shown) is inserted into the central module (2.1), and thereafter interconnected by the push valve (3), which actuated by the piston (4) interconnected through the holes (3.1), drives the prosthesis 5 continuous compression through the toecap (2.2) until its introduction into the surgical incision.

According to figures 5 and 6, the conical shape of the toecap

(2.2) helps to protect the edges of the surgical scar and maintains the positioning of the equipment during the insertion of the prosthesis.

According to figures 7 and 8, the push valve (3)

The semi-cylindrical, interconnected base and vertex first push the contents of the prosthesis, performing a contralateral pressure on the prosthesis wrap from the inside, which is responsible for facilitating the introduction of the prosthesis into the incision.

According to figure 9, the edges and ends of the piston

(4) are blunt and totally atraumatic, avoiding any damage to the prosthesis and allowing to maintain a homogeneous pressure on the prosthesis surface.

The device (1) may be made of plastic material, surgical steel, or any other material that allows sterilization, and may be adapted for various types of silicone prosthesis implant surgery, such as gluteus, or any other type of prosthesis that the cohesiveness allow.
