Abstract

PURPOSE:To improve the accuracy of an identification by providing a laser pointer device to be installed separately from a medical photographing device and to indicate a necessary point in an image, which is photographed with the medical photographing device and displayed, to a subject by means of the crossing point of a multidirectional laser light. CONSTITUTION:An operation supporting laser pointer 2 is installed on a ceiling 3 in a room where an X-ray CT scanner device 1 is installed, connected to a computer 1C of the X-ray CT scanner device 1, and operated under the control of the computer 1C. The computer 1C gives commands to respective drivers so as to drive a motor for rotating a supporting body 2A and motors 2C1 and 2C2 for rotating first and second laser heads 2B1 and 2B2 based on coordinates data. To the coordinates on the operation field of a real subject PA corresponding to the coordinates on a picture, a crossing point P1 of laser lights l11 and l12 is set. Thus, an operator can execute the operation by confirming the fact that the crossing point P1 to appear on the operation field of the subject PA is a tumor part.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention is an object of the present invention to identify lesions such as tumors by observing images of a subject taken using a medical imaging device such as an Xl1CT scanner device. In particular, with regard to a surgical support device that finds a lesion on a screen or a photograph, identifies the lesion on an actual patient, and targets the identified site for surgery, it is possible to improve the accuracy of identification. The present invention relates to a surgical support device.

(Conventional technology) For example, in tumor removal surgery, X-ray diagnostic equipment is used.

The operator observes the photographed image (or fluoroscopic image) obtained by the XHiACT scanner device, magnetic resonance diagnostic device, etc. on a monitor or photograph as an image diagnosis to find the tumor area, and the operator observes the tumor on the screen or in the photograph as a treatment. It is common to identify the tumor site in an actual subject and target the identified site for surgery.

(Problem to be Solved by the Invention) The conventional identification method described above is that the operator estimates the location of the tumor in the actual subject by observing the displayed or photographed image. This largely depends on the surgeon's intuition based on his or her experience, and depending on the surgeon, the accuracy of identification may be low, which can be extremely problematic clinically.
