no. 1 Embodiment approach
[0047] Next, a medical device 1 according to a first embodiment of the present invention will be described with reference to the drawings. Such as figure 1 As shown, the medical device 1 navigates the front end portion 2C of the insertion portion 2A of the endoscope device 2 from the throat portion 7A of the subject 7 as the insertion start position via the bronchi 9 having a plurality of branch portions J1 to J5 . It is inserted into the target site 9G which is the target position. figure 1 It is a three-dimensional model diagram showing a state in which the insertion unit 2A is inserted toward the target site 9G. The insertion portion 2A has a channel 8 inserted through the inside, and the surgical instrument 6 inserted through the channel insertion port 8A protrudes from the distal end portion 2C to perform biopsy of the target site 9G. In addition, in the following drawings, the Z-axis direction is the body axis of the subject 7 , the X-axis direction is the left-right d...
no. 2 Embodiment approach
[0114] Next, a medical device 1A according to a second embodiment of the present invention will be described with reference to the drawings. Since the medical device 1A is similar to the medical device 1, the same constituent elements are given the same reference numerals and their descriptions are omitted.
[0115] Such as Figure 14 As shown, in the medical device 1A, the VBS image is not displayed on the navigation screen, and the second route image PR2 representing the insertion route R is displayed superimposed on the real image.
[0116] To insert the second route image PR2 into the real image, first, the second route image PR2 superimposed on the VBS image corresponding to the real image is generated, and then the generated second route image PR2 is superimposed on the real image.
[0117] The surgeon can perform the insertion operation while confirming the insertion route R through the second route image PR2 superimposed on the real image and grasping the position of ...
no. 3 Embodiment approach
[0137] Next, a medical device 1D according to a third embodiment of the present invention will be described with reference to the drawings. Since the medical device 1D is similar to the medical device 1, the same constituent elements are given the same reference numerals and their descriptions are omitted.
[0138] Such as Figure 20 As shown, a magnetic field sensor 21 as a position sensor is disposed on the front end 2C of the insertion part 2A of the medical device 1D, and the position calculation unit 20D calculates the position, direction and rotation angle of the front end 2C based on the data of the magnetic field sensor 21.
[0139] The position calculation unit 20D detects the position of the distal end portion 2C and the like by detecting the magnetic field from the plurality of magnetic field generating antennas 22 arranged outside the subject 7 by the magnetic field sensor. That is, since the position of the magnetic field sensor 21 and the position of the imaging...
