Description

  The present invention, when performing breast reconstruction using autologous tissue, makes a foaming cup for breast reconstruction used for filling the autologous tissue and adjusting and restoring the shape and size of the breast before excision of the patient. The present invention relates to a method and a forming cup for breast reconstruction produced by the method.

  Psychological distress due to breast loss in patients who have undergone breast resection due to breast cancer or the like is significant and may lead to a decline in quality of life. For this reason, breast reconstruction that has been expected to improve QOL by returning the breast to its original state as much as possible has been performed. Breast reconstruction includes a method of reconstructing a breast by embedding an artificial breast (implant) in the chest and a method of reconstructing the breast by inserting an autologous tissue into the chest (hereinafter referred to as “self-tissue reconstruction”).

  Autologous tissue reconstruction that can be applied to many cases that have undergone breast resection, including cases in which the pectoral muscle is not preserved, requires adjustment of the collected patient's own tissue to the shape and size of the breast before resection It becomes. Conventionally, an operation of adjusting an autologous tissue to a shape and size of a breast before excision is performed by an operator's intuition and experience, imitating a breast before excision and a remaining breast that has not been excised. In addition, as a material used to adjust the autologous tissue to the shape and size of the breast before excision, the breast is transferred by placing silicone rubber on the surface of the breast before excision, curing it, and then removing it from the breast. There is a female breast type (see Patent Document 1).

JP2013-330 (Claim 1, Claim 5, Paragraph [0019] to Paragraph [0022])

However, the work of adjusting the self-tissue to the shape and size of the breast, simulating the breast before the resection or the remaining unremoved breast, depends greatly on the skill of the operator, and the shape of the breast before the resection・ It may be difficult to restore the size.
Moreover, since the breast is pressed down by the weight of the silicone rubber in the breast female mold described in Patent Document 1, the deformed breast is transferred to the drooping state, and correction is made after removing the cured silicone rubber from the breast. However, the shape of the breast before excision cannot be reproduced, and the breast shape before excision cannot be restored due to the use of a female breast, and the right and left breasts may not be balanced. In addition, the patient is restrained and burdened until the silicone rubber is cured.

  The present invention has been made in view of the above-described circumstances. The self-tissue collected from the patient is filled and adjusted to the shape and size of the breast before resection and restored without depending on the skill of the operator. It is an object of the present invention to provide a method for producing a breast reconstruction foaming cup that can be reduced and the burden on the patient is reduced, and a breast reconstruction foaming cup that is adjusted by the method.

The inventors of the present invention have come up with the present invention as a result of intensive studies to solve the above-mentioned problems.
That is, the present invention relates to a method for producing a breast reconstruction foaming cup used for filling an autologous tissue to adjust and restore the shape and size of the breast before excision of the patient. Obtaining a three-dimensional shape of the chest before excision, designing a chest model from the three-dimensional shape data of the three-dimensional shape, producing the chest model based on the design data, and heating The gist of the present invention is a method for producing a forming cup for breast reconstruction, comprising the steps of covering and closely attaching a softened plastic film to the model and removing the plastic film from the model after cooling.

  The invention with the above configuration can produce a breast reconstruction forming cup that can accurately reproduce the shape and size of the breast in the standing or sitting position before resection. Note that “the breast before excision of the patient” includes a breast remaining after excision of one of the breasts. “Chest” refers to the part of the breast that includes the breast. Breast reconstruction is performed not only when the breast is removed by breast cancer surgery, but also when the breast is removed due to trauma or malformation.

  In the above invention, the three-dimensional shape of the breast that remains without being excised in the step of designing the model may be reversed to the excision side. In the above invention, the plastic film may be transparent.

  The gist of the forming cup for breast reconstruction produced by the method described above.

According to the method of the present invention, the shape and size of the breast in the standing or sitting position before excision of the patient can be accurately reproduced. Therefore, the breast in the standing or sitting position before excision can be obtained by filling and adjusting the self-tissue. A forming cup for breast reconstruction that can be restored to the shape and size of the breast can be produced.
In addition, according to the method of the present invention, it is only necessary to photograph a patient's chest with a three-dimensional shape measuring machine such as a 3D scanner, so that the patient's restraint time is short and the burden on the patient is reduced. Can be made.

  According to the forming cup for breast reconstruction of the present invention, the breast restored to the shape and size of the breast in the standing or sitting position before the excision of the patient can be reconstructed using the autologous tissue.

It is explanatory drawing which shows the state which coat | covers a model with a plastic film and attracts | sucks with a vacuum. It is a front view of the foaming cup for breast reconstruction which concerns on this invention of the state with which the autologous tissue was filled.

  Hereinafter, a method for producing a forming cup 50 for breast reconstruction and a forming cup 50 for breast reconstruction according to the present invention will be described with reference to the drawings.

  Acquisition of a three-dimensional shape of the chest in a patient in a standing or sitting position can be performed using a three-dimensional shape measuring machine that measures the three-dimensional shape numerically, such as a 3D scanner. The 3D scanner is not particularly limited as long as the three-dimensional shape of the chest can be acquired, and a commercially available one can be used.

The chest model 20 shown in FIG. 3 can be designed from 3D shape data of the 3D shape obtained above using 3DCAD or the like. When designing the chest model 20 after the removal of one breast, it can be performed by inverting the three-dimensional shape of the remaining breast without being removed to the resection side.
As a result, the remaining breast can be reproduced as a resected breast. The 3D CAD is not particularly limited as long as the chest model 20 can be designed from the three-dimensional shape data, and a commercially available product can be used.

  Next, the chest model 20 shown in FIG. 3 can be produced by NC machining, 3D printer, or the like based on design data by 3D CAD or the like. Examples of the material used for producing the chest model 20 include plastics and ceramics, but are not limited to these as long as they are not deformed by heat. The apparatus used for NC machining is not particularly limited as long as the chest model 20 can be cut from a material such as plastic or ceramics based on the design data, and a commercially available apparatus can be used. The 3D printer is not particularly limited as long as it can output the chest model 20 based on the design data, and a commercially available one can be used.

  Further, the design of the chest model 20 from the above three-dimensional shape data and the production of the chest model 20 based on the design data can also be performed using a 3D CAD / CAM system. The 3D CAD / CAM system is not particularly limited as long as the chest model 20 can be designed and manufactured, and a commercially available product can be used.

  Next, as shown in FIG. 3, the produced chest model 20 is covered with a plastic film 25 softened by heating, and a gap between the chest model 20 and the plastic film 25 is indicated by an arrow (not shown) by a vacuum pump. The plastic film 25 adheres by sucking in the direction. After cooling, the forming cup 50 for breast reconstruction can be produced by removing the plastic film 25 from the chest model 20. Examples of the plastic film 25 include polypropylene, polyethylene, polyethylene terephthalate, polystyrene, and polyvinyl chloride, but there is no particular limitation as long as it is a thermoplastic resin film. The plastic film 25 is preferably transparent. When the plastic film 25 is transparent, the self-tissue 30 can be seen from below the breast reconstruction foaming cup 50 by lifting the breast reconstruction foaming cup 50 filled with the autologous tissue 30 in the breast part 1 onto the face. Therefore, the self-organizing work can be adjusted when viewed from above and below the breast reconstruction forming cup 50, and the shape and size of the breast can be reproduced more accurately and the operation time can be shortened. The plastic film 25 is usually heated at 200 to 300 ° C., but is not limited to this temperature as long as the plastic film 25 to be used can be softened so that it can be covered with a model.

  As shown in FIGS. 1 and 2, the breast reconstruction forming cup 50 manufactured as described above includes a breast part 1 and a peripheral part 2. The breast part 1 is composed of a concave part that accurately reproduces the shape and size of the breast before the patient stands or sits and the breast part 1 and the areola part 4 reproduce the teat and the areola. . The breast reconstruction forming cup 50 manufactured in this way can be adjusted and restored to the shape and size of the breast before the patient's standing or sitting position is removed, and the breast can be reconstructed.

  Next, a method of using the breast reconstruction forming cup 50 according to the present invention will be described. First, in the operating room, a predetermined amount of the patient's own tissue 30 necessary for the reconstruction of the breast is collected, as predicted from the shape and size of the breast portion 1 of the sterilized forming cup 50 for breast reconstruction, as shown in FIG. As shown, the breast portion 1 of the breast reconstruction forming cup 50 is filled. In the case of the latissimus dorsi flap, the autologous tissue 30 is a part of the skin / fat / muscle on the back, in the case of the rectus abdominal flap, the part of the skin / fat / muscle in the abdomen, Collect abdominal skin and fat. Then, the part of the self tissue 30 that protrudes from the breast part 1 of the breast reconstruction forming cup 50 is excised, or when the thickness of the self tissue is thin, the part that protrudes is folded back, and the excised part and the folded part are stitched. The autologous tissue 30 performs adjustment so that the shape and size of the breast before excision can be accurately restored. The adjusted autologous tissue 30 can then be inserted into the patient's chest and sutured to the chest tissue to rebuild the breast. Further, by using a forming model (not shown) prepared by filling the breast portion 1 of the breast reconstruction forming cup 50 with silicon prior to the collection of the self-tissue 30, the shape, size, and amount of collection of the flaps to be collected are used. Or the position etc. which sew the autologous tissue 30 to a chest can also be confirmed accurately beforehand. In general, the nipple and areola are reconstructed several months after the reconstruction of the breast. If sufficient skin does not remain in the chest due to mastectomy, an expander may be inserted in advance at the breast excision site, and the tissue may be gradually expanded before breast reconstruction.
