Definitions
- the heat of the heating element is not easily radiated to the outside of the housing due to the heat radiation resistance between the outer peripheral surface of the hollow tube and the inner wall surface of the housing. Therefore, it is easy to keep the temperature in the hollow space of the hollow tube, that is, the temperature around at least the movable part of the vibration element constant. Therefore, it is suitable for reducing the distortion of the scanned image by suppressing the change in the characteristics of the vibration element depending on the temperature change.
- An integrated endoscope is an apparatus that integrally includes an electronic endoscope equipped with a solid-state imaging device that images a subject via an objective optical system and the scanning probe. is there.
- a predetermined heat insulating tape is wound around the outer wall surface of the housing, and the housing in which the heat insulating tape is wound and the solid-state imaging device are accommodated in parallel in the distal end portion of the integrated endoscope. It is supported.
- a three-dimensional image is obtained by stacking two-dimensional images corresponding to the respective axial positions.
- the image processing controller 320 converts the generated 3D image signal into a video signal conforming to a predetermined standard such as NTSC or PAL, and outputs the video signal to the monitor 300M.
- a predetermined standard such as NTSC or PAL
- the confocal optical system unit 140 includes a hollow tube 1411, a heater 1412, a temperature detection sensor 1413, and a heat insulating tape 1414.
- the hollow tube 1411 is a metal part having a substantially cylindrical shape, and is bonded and fixed to the mount member 1403.
- the hollow tube 1411 has at least a movable portion (a portion that vibrates when voltage is applied) of the emission end portion 1401a of the confocal optical fiber 1401 and the piezoelectric tube 1404. Is housed.
- the temperature management controller 330 controls the heater 1412 based on the temperature detected by the temperature detection sensor 1413, and maintains the inside of the hollow space 1411a at a predetermined constant temperature via the hollow tube 1411.
- the temperature in the hollow space 1411a is maintained at a temperature (for example, 42 ° C. to 43 ° C.) that is higher than the body temperature and the like and does not affect the living body.
- the temperature control range in the hollow space 1411a is appropriately set according to the imaging purpose and application of the confocal imaging system, the physical properties of various components constituting the confocal optical system unit 140, and the like.
- the entire circumference of the hollow tube 1411 (between the outer peripheral surface of the hollow tube 1411 and the inner wall surface of the inner cylinder 1402I) is covered with an air layer. Since the air layer acts as a high heat dissipation resistance, the heat of the heater 1412 is not easily radiated to the outside of the inner cylinder 1402I. Therefore, in the confocal optical system unit 140 of the present embodiment, it is easy to keep the temperature in the hollow space 1411a constant.
- the heat of the heater 1412 is radiated into the hollow space 1411a in a state in which the unevenness of heating distribution inherent to the heater 1412 is reduced by once conducting through the hollow tube 1411. Therefore, the change in the characteristics of the piezoelectric tube 1404 depending on the temperature change can be more suitably suppressed, and the distortion of the scanned image can be further reduced.
- the scanning probe 130 and the electronic scope are configured as an integrated device (integrated endoscope 100).
- the scanning probe 130 and the electronic scope are separately provided. You may comprise as an apparatus of.
- the scanning probe 130 is used in a state of being inserted into a forceps channel provided in an electronic scope, for example.
- FIG. 4 is a cross-sectional view showing the internal structure of the confocal optical system unit 140Y of another embodiment.
- the same or similar components as those in the confocal optical system unit 140 in FIG. 2 are denoted by the same or similar reference numerals, and description thereof will be simplified or omitted.
- the heat radiation resistance covering the entire circumference of the hollow tube 1411 is an air layer.
- the heat insulation member 1415 filled between the inner wall surfaces of the cylinder 1402I is good also as the heat insulation member 1415 filled between the inner wall surfaces of the cylinder 1402I.
