発明の名称 (英語) RESECTION PROCESS ESTIMATION DEVICE AND RESECTION PROCESS NAVIGATION SYSTEM UPDATE
発明の概要(英語) This resection process estimation device is configured from: a surgery process case database storing case data of surgery processes describing information relating to incision surfaces for resected sites of organs of interest and the procedure for resection; a standard resection process generation unit that reads out case data appropriate for a site to be resected specified by a user from the surgery process case database and generates a standard incision surface and a standard resection process on the basis of a plurality of pieces of read case data; an anatomical reference point extraction unit that extracts an anatomical reference point from patient-specific three-dimensional medical image data; and a patient-specific resection process estimation unit that matches the standard incision surface and the standard resection process to the patient-specific three-dimensional medical image data and estimates a patient-specific incision surface and a patient-specific resection process.
従来技術、競合技術の概要(英語) BACKGROUND ART
The cut-off portion of the cut-off in accordance with the internal structure of the surgical plan can be grasped in advance, a physician or other medical practitioner (hereinafter ' medical professionals' is called.) Is extremely important.The cut-off strategy, separating a portion of the organ, disconnects the internal structure of the site, of the operator depends on the experience.For example an internal organ such as a blood vessel of the importance of the structure so as to extend along the female (a female as well, including disconnection of the other appliances as well.Hereinafter referred to as a 'female'.) So as to develop the, and the blade has reached a predetermined depth of the structure of an internal organ can be confirmed, at that time to stop the progress of the female, female from another location is now placed in such a manner as to progress to a predetermined depth is.In this case, first the evolution of the female 2, and passed to the first portion into the opposite side of the organ surface as long as a method, and an extending direction of the female first placed in a slightly different direction is also a method.
In this way, the cut-off schedule, the progress through a combination of many factors, among them, the structure of the internal organ or tumor blood vessels, their three-dimensional positional relation between the estimated organ from the outside, first it is determined that the start of the disconnection is very important to determine the site of the present invention.If, the cut-off is started when no suitable sites, a medical practitioner, the optimum site is necessary to rearrange the female, female organ is unnecessary due to restarts the disconnection due to the burden.
In addition, the cut-off or error in the direction of progress, or development of an error and the depth, the cut-off of the internal organs is an important indicator in the development of an anatomical structure (e.g. a blood vessel, lymphatic vessels and other vascular structure) cannot be confirmed, with the development of the following steps of the disconnection problems arise.In addition, the order of disconnection is inappropriate (for example, the first is not appropriate in a case the female part), as well as the margin of the tumor and not balanced, cause unnecessary bleeding, as a result unnecessary disconnection is required.
Therefore, by a medical practitioner to assist in the understanding of the internal organ, the current, and the image processing techniques using visualization techniques have been widely utilized for various kinds of software.Patent Document 1 is for example, present in the target organ from the position of the abnormal region, the target organ and the organ position in the vicinity of the positional relationship between the cut-off in consideration of such as the surgery-assistance apparatus and method have been described (see paragraph 0010).Specifically, in Patent Document 1, the cut-off method to minimize the volume to be cut, the cut-off method to minimize the surface area to be cut, the cut-off portion to minimize the distance from the surface of the cut-off method is a technique.
In addition, in Patent Document 2, the degree of deformation of an organ during surgery simulation image by taking into consideration the image diagnosis support technique (see paragraph 0006) are described.Specifically, in Patent Document 1, which are connected to each other adjacent vertices of a tetrahedron block (so-called polygons) formed by the tetrahedral model for any disconnection of the pattern can be previously calculated, the position of the cut-off by a medical practitioner to provide a simulation image corresponding to the designation of the technology.
