Description

Nipple areola protection device for breast subcutaneous gland resection

Technical Field

The utility model relates to an auxiliary appliance for breast surgery, in particular to a nipple areola protection device for breast subcutaneous gland resection.

Background

The nipple is the focus of vision of the breast, and the protection of the nipple and the supply of blood should be fully appreciated during any breast surgery.

The tumor safety of breast cancer patients undergoing mastectomy with the papillary areola complex remaining has been documented. Although the papillary areola complex (NAC) has two systems, namely, a hypodermal blood vessel network and a blood vessel network in a mammary gland body, blood supply of the complex is guaranteed, a mammary subcutaneous gland resection (hereinafter referred to as NSM) for retaining the papillary areola complex can cause the deficiency of blood supply from the NAC mammary gland body, only blood supply of the hypodermal blood vessel network is left, repeated traction in the operation, electric power cauterization heat conduction, postoperative pressure dressing, compression of skin flaps by intramammary implants and the like can cause the aggravation of ischemia of the fragile hypodermal blood vessel network, and the conditions of nipple loss, skin flap infection, prosthesis loss, reconstruction failure and the like are caused by serious patients.

Thanks to the rapid development of the diversity of treatment means and the accessibility of drugs, the survival rate of breast cancer is not reduced although the incidence rate is increasing, on the contrary, the treatment effect of breast cancer is increasing, long-term survival becomes possible, and the focus of attention of patients is shifting from the worry about death to the attention of appearance and the need for quality of life. NSM breast reconstruction surgery is becoming increasingly popular with patients due to the good cosmetic results and assurance of tumor safety.

However, the nipple-areola complex has thin skin and delicate tissue, and is particularly fragile after trauma such as operation, so that the nipple-areola ischemia is caused by reduction of blood supply, poor compression and the like, and serious patients have the conditions of nipple necrosis and drop, prosthesis exposure and loss and the like, so that NSM breast reconstruction operation fails, and great physical and psychological damage is brought to patients.

Therefore, it is a technical problem to be solved at present that how to provide sufficient protection for the nipple-areola complex in the intraoperative and postoperative rehabilitation stages and reduce the probability of NSM operation failure.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a nipple areola protection device for breast hypodermal gland resection, which protects a nipple through a top support part, a backing ring is attached to the areola and uniformly releases the pressure on the epidermis of the areola, so that the blockage of blood flow of a hypodermal blood vessel network caused by the pressure on the nipple areola is avoided, the blood supply of the nipple areola is improved, the drop of the nipple areola is prevented, the postoperative rehabilitation is accelerated, and the nipple areola protection device helps to bridge the vulnerable period until the nipple is completely healed.

In order to realize the purpose of the utility model, the utility model adopts the following technical scheme: a nipple areola protection device for breast hypodermal gland resection comprises a hard shell and a flexible liner, wherein the hard shell comprises a top support and a backing ring; the shape of the supporting piece is matched with that of a female nipple; the backing ring is annular, and the jacking piece is fixed in the middle of the backing ring; the flexible lining is permeable to air and water and has permeability, and is attached to one surface of the top support piece and one surface of the cushion ring contacting with the skin of the human tissue.

Compared with the prior art, the nipple areola protection device for the breast subcutaneous gland resection adopting the technical scheme has the following beneficial effects:

the nipple areola protecting device for the breast hypodermal gland resection, provided by the utility model, has the advantages that the top supporting piece can be covered on the outer side of the nipple to protect the nipple, so that the nipple is prevented from being inclined and folded due to the fact that the nipple is pressed by postoperative clothes or other articles, the blood supply of a hypodermal blood vessel network of the nipple is blocked, and the nipple is prevented from falling off due to insufficient blood supply.

And the backing ring is used for protecting the skin of the areola part, so that the areola part is uniformly pressed, and the blood supply insufficiency of the areola part caused by local pressing is prevented.

Thirdly, the backing ring can provide certain support for the top support piece so as to keep the pressure of the top support piece to be uniformly applied to the areola part when the top support piece is pressed and prevent the top support piece from falling or deflecting.

And the flexible lining is permeable to air and water and has permeability, so that the medicine can permeate and diffuse to the surface of the nipple-areola complex to help the nipple-areola complex to recover quickly.

Therefore, the nipple-areola protective device can provide enough protection for a nipple-areola complex, and simultaneously, in a preferred scheme, the hard shell and the flexible lining both have drug penetration capacity, so that drugs can be sprayed on the outer part of the protective device to penetrate into the surface of the complex, time and space are provided for the formation of a new blood system of the complex, and the protective device is helped to pass through a postoperative fragile period until the complex is completely healed.

Wherein, the hard shell is preferably made of plastic or composite material; certain hardness is required to play a supporting role; all edges or lines must be smooth and free of burrs and corners to prevent the hard shell edges from pressing the skin and causing insufficient blood supply.

In the case of a flexible liner with sufficient permeability, the rigid outer shell may be impermeable to water and gas, but for skin permeability, it is preferred that the rigid outer shell be permeable to water and gas.

Wherein the hard shell is densely covered with permeable through holes (see fig. 5), or the hard shell is made of hard material in a grid shape (see fig. 4, such as hard plastic net).

Secondly, the hard shell can be made of air-permeable and water-permeable hard materials, such as wood, porous and loose composite materials (such as carbon fiber, cement, petrochemical sponge and the like) and the like.

Referring to fig. 3, the flexible liner preferably extends to the backing ring peripheral edge forming a bead that wraps around the backing ring peripheral edge. Utilize flexible inside lining to form the turn-up parcel in the backing ring outside for the backing ring outside is softer and bigger with the area of contact of skin, avoids local pressurized and causes the blood not smooth.

Preferably, the backing ring is a conical ring surface. Can be better attached to the skin of the areola part.

Preferably, the top support part is in an inverted U shape, and is more adaptive to the shape of the nipple.

Referring to fig. 6, the periphery of the cushion ring is preferably further provided with a plurality of fixing pieces, the fixing pieces are used for assisting in applying adhesive and fixing the whole nipple areola protecting device, the fixing pieces are made of the same material as the flexible lining, and the fixing pieces are made of skin-friendly breathable water-permeable fabric.

Referring to fig. 7, the bottom of the fixing sheet is preferably provided with anti-slip round particle points to avoid the nipple areola protector from slipping and prevent the application from falling off to cause the protector to fall off.

Referring to fig. 7, preferably, the surface of the fixing sheet is provided with a plurality of slits for ventilation, the application is attached to the fixing sheet, and if the ventilation of the application is insufficient, a knife can be used to cut an opening along the slits on the application surface.
