Abstract

The present invention relates to a customized surgical guide device and a customized surgical guide generating method and program. A customized surgical guide generating method comprises the steps of: acquiring body surface data and treatment area data from medical image data by a computer; a first shape data generating step, wherein the first shape data is data which corresponds to the shape of the body part cover; a target point setting step of setting one or more target points; setting individual first points on the body surface accessible to the target point with a medical tool; setting a guide tube length on the basis of a distance from the first point to the target point; and generating final shape data in which one or more guide tubes are combined to the first shape data by applying the guide tube length to the first point.

First claim

What is claimed is:

1. A customized surgical guide comprising:
a plurality of guide tubes through which medical instruments are insertable; and
a body portion cover configured to cover a surface of a breast of a patient,
wherein the body portion cover is coupled to the plurality of guide tubes, wherein the body portion cover has holes through which the medical instruments pass,
wherein the medical instruments are configured to pass through the plurality of guide tubes and then through the holes toward the breast,
wherein the body portion cover is shaped to conform to the surface of the breast,
wherein the body portion cover defines positions of the plurality of guide tubes such that the medical instruments reach target points within the breast,
wherein a respective guide tube of the plurality of guide tubes has a larger inner diameter than an outer diameter of a respective medical instrument of the medical instruments,
wherein the respective guide tube has a length sized such that an insertable depth of the respective medical instrument into the body is limited to a set depth from a respective first point of first points to a respective target point of the target points,
wherein the first points are present on the surface of the breast, at which the plurality of guide tubes are configured to be located,
wherein the target points are present on a surface of or inside a treatment target region, or are spaced by specific distances from the treatment target region.

2. The customized surgical guide of claim 1 , wherein the respective the medical instrument is a syringe including a needle having a specific needle length, and the respective guide tube is formed so that the needle of the syringe reaches the respective target point,
wherein the respective target point is a starting point of a dye column, and
wherein the dye column is configured to formed by a dye being supplied by the syringe during the syringe that is fully inserted into the guide tube is removing away from the respective target point through the respective guide tube.

3. The customized surgical guide of claim 1 , wherein the respective medical instrument is configured to perform treatment on a treatment range defined as a specific range from a specific point which the inserted respective medical instrument reaches, the respective target point is at least one specific point located within the treatment target region, wherein the at least one specific point defines at least one treatment range covering the treatment target region, wherein a number of the guide tubes is equal to a number of the target points, wherein the respective guide tube is formed on the respective first point of the body portion cover and extends in a direction from the respective first point toward the respective target point.

4. The customized surgical guide of claim 1 , wherein the body portion cover is formed to conform to body surface acquired based on medical image data, and wherein the respective guide tube has a length set based on a respective distance on the medical image data from the respective first point on the body surface to the respective target point that the respective medical instrument is configured to reach.

5. The customized surgical guide of claim 1 , wherein the body portion cover is configured to fix a shape of the breast into a specific shape that is measured when body surface data and treatment region data are acquired by a computer from medical image data.

6. The customized surgical guide of claim 1 , wherein when a distal end of the respective medical instrument reaches the respective target point, the respective guide tube is fitted with the respective medical instrument.

7. The customized surgical guide of claim 1 , wherein the body portion cover comprises a nipple hole having the same size as a nipple of the breast at a position corresponding to the nipple of the breast.

8. The customized surgical guide of claim 1 , wherein the target points are points on a three-dimensional space of the treatment target region having a three-dimensional breast shape.

9. A method of producing a customized surgical guide, the guide including a plurality of guide tubes through which medical instruments are inserted, and a body portion cover contacting a surface of a breast of a patient, the method comprising:
acquiring, by a computer, body surface data and treatment region data from medical image data;
generating, by the computer, first shape data based on the body surface data, the first shape data defining a shape of the body portion cover;
setting, by the computer, target points, which are present on a surface of or inside a treatment target region;
setting, by the computer, a respective first point of first points, on the body surface from which the medical instruments are accessible to a respective target point of the target points;
setting, by the computer, a respective length of a respective guide tube of the plurality of guide tubes based on a respective distance from the respective first point to the respective target point; and
applying, by the computer, the respective guide tube length to the respective first point to generate last shape data as a combination between the first shape data and shape data of the respective guide tube.

10. The method of claim 9 , wherein the respective medical instrument is a syringe including a needle having a specific needle length, and the respective guide tube is formed so that the needle of the syringe reaches to the respective target point,
wherein the respective target point is a starting point of a dye column, and
wherein the dye column is configured to formed by a dye being supplied by the syringe during the syringe that is fully inserted into the respective guide tube is removing away from the respective target point through the respective guide tube.

11. The method of claim 10 , wherein the setting of the respective first point includes setting the respective first point from which the respective medical instrument reaches the respective target point without passing through the treatment target region.

12. The method of claim 9 , wherein the respective medical instrument is configured to perform treatment on a treatment range defined as a specific range from a specific point which the respective inserted medical instrument reaches, the respective target point is at least one specific point located within the treatment target region, wherein the setting of the respective target point includes setting the respective target point to define at least one treatment range covering the treatment target region.

13. The method of claim 9 , wherein the generating of the first shape data includes:
obtaining entire shape data of the breast; and
generating shape data of the body portion cover covering the breast based on the entire shape data,
wherein the body portion cover covers the breast and fixes a shape of the breast into a specific shape.

14. The method of claim 9 , wherein a first posture of a patient at which the medical image data is taken and a second posture of the patient at which surgery is performed are different, the method further comprises:
calculating a positional change of the treatment target region when a posture of the patient changes from the first posture to the second posture,
wherein the setting of the respective target point, the setting of the respective first point, and the setting of the respective length of the respective guide tube are performed based on the changed position of the treatment target region.

15. The method of claim 9 , wherein the respective medical instrument is c
