Description

[Technical Field]

[0001] The present invention relates to a shape recording set and a shape recording method. [Background technology]

[0002] For example, Patent Document 1 discloses a breast measuring instrument for measuring the three-dimensional shape of a human breast, which comprises a positioning reference part that is placed or fixed at approximately the center of the human chest, a rod-shaped shape measuring part that extends from the positioning reference part and is deformable to fit the three-dimensional shape of the breast and can maintain the shape after deformation, and a measurement gauge that is supported by the shape measuring part and is used to measure the distance between the shape measuring part and the surface of the human chest. However, the breast measuring device described in Patent Document 1 cannot record the shape and size of one breast, nor can it record the positions of the nipple and areola in symmetrical positions, making it impossible to accurately capture the shape and size of the breasts while checking the balance between the left and right breasts.

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will now be described with reference to the accompanying drawings. First, the configuration of a shape recording set 1 according to this embodiment will be described. FIG. 1 is a six-view diagram illustrating a three-dimensional shape recorder 3 in a shape recording set 1 according to an embodiment. FIG. 2 is a six-view diagram illustrating the two-dimensional shape recorder 5 in the shape recording set 1 according to the embodiment. The shape recording set 1 in this example is a medical instrument used for breast reconstruction. The shape recording set 1 is used as a measuring instrument for directly measuring the healthy breast and recording its shape and size, and can also be used as a mold during breast reconstruction surgery. The breast is an example of an object to be recorded. As illustrated in Figures 1 and 2, the shape recording set 1 has a three-dimensional shape recorder 3 and a two-dimensional shape recorder 5.

[0013] The three-dimensional shape recorder 3 shown in Figure 1 is an instrument for recording the shape and size of one breast, and has a base 30, a rod-shaped deformable member 32, and a scale 34. The three-dimensional shape recorder 3 has chamfered corners overall so that it does not hurt the skin when it comes into contact with it. The base 30 is a base portion located at the base end of a rod-shaped deformation member 32, which will be described later. The front and back surfaces of the base 30 may be formed into a convex curved shape to increase resistance to deformation.

[0014] The rod-shaped deformation members 32 are multiple rod-shaped deformation members extending in different directions from the base 30. The rod-shaped deformation members 32 include at least three rod-shaped deformation members that are perpendicular to one another. In this example, the rod-shaped deformation member 32 includes four rod-shaped deformation members 32A to 32D that are perpendicular to one another on the same plane, forming a cross shape. The length of the rod-shaped deformation member 32A is approximately twice as long as the other rod-shaped deformation members 32B to 32D. Note that the rod-shaped deformation members 32A to 32D have substantially the same configuration, and will be simply referred to as rod-shaped deformation member 32 unless there is a need to distinguish them.

[0015] The scale 34 is a mark that indicates length and is displayed on the surface of the rod-shaped deformation member 32. The scale 34 further includes a distance indicator that displays the distance from a reference point O set at the center of the base 30. In this example, the scale 34 is engraved with a laser and displayed on each of the rod-shaped deformation members 32A to 32D. The scale 34 engraved from the reference point O to the end of the rod-shaped deformation member 32A displays distances from 0 cm to 20 cm. The scale 34 engraved from the reference point O to the end of the rod-shaped deformation member 32B displays distances from 0 cm to 10 cm. Similarly, the engraved scales 34 from the reference point O to the rod-shaped deformation member 32C and from the reference point O to the rod-shaped deformation member 32D display substantially the same as those on the rod-shaped deformation member 32B.

[0016] The three-dimensional shape recorder 3 is deformable and has a hardness that allows it to retain its shape after deformation. The three-dimensional shape recorder 3 can be deformed by the force of a human hand or finger. The material of the three-dimensional shape recorder 3 may be any material that is hard enough to deform and retain its shape after deformation. For example, a metal alloy, preferably a tin alloy, can be used as the material. The tin content of the tin alloy is 95 wt% or more, preferably 97 wt% or more, and more preferably 99 wt% or more. The three-dimensional shape recorder 3 of this example is formed from a tin alloy with a tin content of 99% or more. The longitudinal dimension A of the three-dimensional shape recorder 3 is 30 cm or more and 32 cm or less, and in this example, is 31 cm. The lateral dimension B of the three-dimensional shape recorder 3 is 20 cm or more and 22 cm or less, and in this example, is 21 cm. The thickness dimension C of the three-dimensional shape recorder 3 is 1.5 mm or more and 2.5 mm or less, and in this example, is 2.0 mm. Here, if the thickness dimension C is less than 1.5 mm, it can be deformed by the force of a person's hand or fingers, but the hardness will be such that it cannot maintain the deformed shape. If the thickness dimension C exceeds 2.5 mm, it can maintain the deformed shape, but the hardness will be such that it is difficult to deform by the force of a person's hand or fingers. Therefore, if the thickness dimension C is 2.0 mm, it can be deformed by the force of a person's hand or fingers, and the hardness will be such that it can maintain the deformed shape. Furthermore, the width dimensions D and E of the three-dimensional shape recorder 3 are 0.8 cm or more and 1.2 cm or less, and in this example, they are 1.0 cm.

[0017] The two-dimensional shape recorder 5 is an instrument that records the shape and size of one breast and the positions of the nipple and areola in symmetrical positions, and has a linear deformation member 52 and a scale 54. The two-dimensional shape recorder 5 has chamfered corners overall so that it does not hurt the skin when it comes into contact with it. The linear deformation member 52 is a linear deformation member that can be deformed by the force of a person's finger and can maintain the shape after deformation. A scale 54 is displayed on the surface of the linear deformation member 52. The scale 54 is a mark that indicates length and is displayed on the surface of the linear deformation member 52. The scale 54 includes a reference point O set at the center position in the longitudinal direction of the linear deformation member 52, and distance indicators 54A that are provided symmetrically from the reference point O and indicate the distance from the reference point O. The scale 54 in this example is engraved with a laser and displayed on the linear deformation member 52. The scale 34 engraved from the reference point O to the end of the linear deformation member 52 indicates distances from 0 cm to 20 cm and is provided symmetrically.

[0018] The two-dimensional shape recorder 5 is deformable and has a hardness that allows it to retain its shape after deformation. The two-dimensional shape recorder 5 can be deformed by the force of a human hand or finger. The material of the two-dimensional shape recorder 5 may be any material that is hard enough to deform and retain its shape after deformation. For example, a metal alloy, preferably a tin alloy, can be used. The tin content of the tin alloy is 95 wt% or more, preferably 97 wt% or more, and more preferably 99 wt% or more. The two-dimensional shape recorder 5 is formed from a tin alloy with a tin content of 99% or more. The longitudinal dimension A of the two-dimensional shape recorder 5 is 40 cm or more and 42 cm or less, and in this example, is 41 cm. The width dimension B of the two-dimensional shape recorder 5 is 0.8 cm or more and 1.2 cm or less, and in this example, is 1.0 cm. The thickness dimension C of the two-dimensional shape recorder 5 is 1.5 mm or more and 2.5 mm or less, and in this example, is 2.0 mm. Here, if the thickness dimension C is less than 1.5 mm, it can be deformed by the force of a person's hand or finger, but the hardness is such that it cannot maintain the deformed shape. On the other hand, if the thickness dimension C exceeds 2.5 mm, it can maintain the deformed shape, but the hardness is such that it is difficult to deform by the force of a person's hand or finger. Therefore, if the thickness dimension C is 2.0 mm, it can be deformed by the force of a person's hand or finger, and the hardness is such that it can maintain the deformed shape.

[0019] Next, a shape recording method according to this embodiment will be described. FIG. 3 is a flowchart illustrating the shape recording method (S10) in this embodiment. FIG. 4A is a diagram illustrating a state in which the shape and size of the breast are recorded in the three-dimensional shape recorder 3. FIG. 4B is a diagram illustrating a state in which the shape and size of the breast are recorded in the two-dimensional shape recorder 5. FIG. 4C is a diagram illustrating a state in which the two-dimensional shape recorder 5 that has recorded the shape and size of the breast is rotated. FIG. 4D is a diagram showing how the three-dimensional shape recorder 3 is deformed to fit the shape of the two-dimensional shape recorder 5 that has recorded the shape and size of the breast. FIG. 4E is a diagram illustrating the state in which the three-dimensional shape recorder 3 is placed at the reconstruction position. As an example, the work process in steps S100 to S108 illustrated in Fig. 3 will be described below with reference to Fig. 4. In this example, the shape recording method uses a specific example in which, while the patient is in a sitting position, shape recording set 1 is used to record the shape of the right breast, which is the healthy side (S100 to S106), and after shape recording, left breast reconstruction surgery is performed while the patient is in a supine position using shape record set 1 as a support guide (S108).

[0020] In step 100 (S100), as illustrated in FIG. 4A, the surgeon using the shape recording set 1 (hereinafter referred to as the surgeon) places the three-dimensional shape recorder 3 illustrated in FIG. 1 on the healthy breast and records the shape and size of the healthy breast in the placed three-dimensional shape recorder 3. Specifically, the surgeon places the base 30 at the position of the nipple of the healthy right breast and positions the end of the rod-shaped deformable member 32A so that it contacts the patient's right clavicle. This determines the placement position of the three-dimensional shape recorder 3. Next, the surgeon deforms the rod-shaped deformable members 32A and 32C to match the external shape of the healthy breast, which is the object to be recorded, to record the external shape of the right breast in the up-down direction, and deforms the rod-shaped deformable members 32B and 32D to record the external shape of the right breast in the left-right direction. In this way, the three-dimensional shape recorder 3 records the shape and size of the right breast. In this step, the case where both the rod-shaped deformation members 32A and 32C, which are the vertical axes, and the rod-shaped deformation members 32B and 32D, which are the horizontal axes, are deformed will be described, but it is also possible to deform only the vertical axes without deforming the horizontal axes. The horizontal axes may be deformed in S106 instead of this step, since the external shape of the breast is re-recorded in S106, which will be described later.

[0021] In step 102 (S102), as illustrated in FIG. 4B, the surgeon places the two-dimensional shape recorder 5 illustrated in FIG. 2 on the patient's chest and records the shape and size of the healthy breast on the placed two-dimensional shape recorder 5. Specifically, the surgeon places the two-dimensional shape recorder 5 so that the longitudinal direction of the two-dimensional shape recorder 5 and the left-right direction of the healthy breast are the same. The surgeon places the reference point O of the two-dimensional shape recorder 5 on the patient's sternum and in a position overlapping with the nipple of the healthy breast. This determines the placement position of the two-dimensional shape recorder 5. Next, the surgeon deforms the two-dimensional shape recorder 5 to match the external shape of the healthy breast and records the external shape of the right breast in the deformed two-dimensional shape recorder 5 in the left-right direction. This allows the two-dimensional shape recorder 5 to record the shape and size of the right breast. The surgeon then checks the distance from the reference point O to the nipple and areola using the scale 54 on the two-dimensional shape recorder 5.

[0022] In step 104 (S104), as shown in Fig. 4C, the surgeon rotates the two-dimensional shape recorder 5, which has recorded the left-right shape and size of the right breast, by 180 degrees, with reference point O as the center of rotation. This allows the left-right shape and size of the right breast recorded in the two-dimensional shape recorder 5 to be flipped left and right and moved to the position that will become the left breast.

[0023] In step 106 (S106), as shown in FIG. 4D , the surgeon places the three-dimensional shape recorder 3 on the two-dimensional shape recorder 5 rotated 180 degrees on the patient's chest, and copies the shape of the two-dimensional shape recorder 5 onto the three-dimensional shape recorder 3. Specifically, based on the distance from the reference point O confirmed in S102 to the nipple and areola, the surgeon places the base 30 of the three-dimensional shape recorder 3 at the position where the nipple and areola will be reconstructed, and places the end of the rod-shaped deformable member 32A in contact with the patient's left clavicle. This determines the placement position of the three-dimensional shape recorder 3 relative to the two-dimensional shape recorder 5. The surgeon deforms the rod-shaped deformable members 32B and 32D of the three-dimensional shape recorder 3 that is placed on the two-dimensional shape recorder 5, adjusting their curved shapes to match the shape of the two-dimensional shape recorder 5, and records the shapes on the rod-shaped deformable members 32B and 32D. As a result, the left-right shape and size of the breast recorded in the three-dimensional shape recorder 3 are reversed.

[0024] In step 108 (S108), as shown in Fig. 4E, the surgeon removes the two-dimensional shape recorder 5 from the patient's chest, leaving the three-dimensional shape recorder 3 on the patient's chest. Then, with the three-dimensional shape recorder 3 in contact with the patient's chest, the surgeon can collect the peripheral fat while visually checking the flow of the fat, and perform the reconstruction surgery. In this way, this method makes it possible to capture the shape and size of a normal breast in a mirrored state at the position where the breast will be reconstructed.

[0025] As described above, according to the shape recording set 1 of this embodiment, the three-dimensional shape recorder 3 and the two-dimensional shape recorder 5 are made of a tin alloy, which allows for flexible shape changes. Furthermore, the antibacterial and sterilizing properties of tin make it hygienic, and tin is less likely to cause metal allergies, making it safer than other metals to come into contact with the skin. In addition, the three-dimensional shape recorder 3 can record the shape and size of one breast, and the two-dimensional shape recorder 5 can record the positions of the nipple and areola in symmetrical positions, so the shape and size of the breasts can be captured more accurately while checking the balance between the left and right breasts.

[0026] [Variations] Next, a modification of the above embodiment will be described. In the above embodiment, the case of capturing the shape and size of the breast, which is the chest, has been described, but the present invention is not limited to this and can be applied to any symmetrical body part as appropriate. Symmetrical body parts include, for example, the chest, abdomen, back, lower back, or genitalia in the trunk, the forehead, vertex, upper jaw, cheek, nose, or lower jaw in the head and face, the upper arm or forearm in the upper limb, or the buttocks, thigh, or lower leg in the lower limb, and are examples of the recorded material of the present invention. Although the embodiments of the present invention have been described above, the present invention is not limited to these, and various modifications and additions can be made without departing from the spirit of the invention.
