Moreover, an opening portion from the upper surface to the lower surface through a front surface of the distal end portion body is extended and open, and thus, an exposed range of the elevator is wide, and the elevator can be cleaned rapidly and easily.

Abstract: Since a lower-surface side opening of an elevator housing slit is closed by a partition wall portion of a cap in normal operation, and a rotating shaft receiving portion of an elevator has a rotating shaft housing groove opened on the side opposite to the lower surface when the elevator is attached to a distal end portion body, the elevator is not removed structurally at an angle of the elevator when the treatment tool is operated to be stood, and a rotating shaft and the rotating shaft receiving portion do not have to be attached excessively tightly. Therefore, a work load in disassembling and assembling of a distal end portion can be set appropriately, and workability in disassembling and assembling is improved. Moreover, as a result, the distal end portion can be cleaned rapidly and easily.

The elevator is avoided from the elevator housing slit by loosely fitting the engagement hole of the elevator to the second shaft portion at cleaning.

Abstract: Some embodiments of the present inventive concept provide a system that uses two wavelengths of differential transmittance through a sample to apply laser speckle or laser Doppler imaging. A first of the two wavelengths is within the visible range that has zero or very shallow penetration. This wavelength captures the anatomical structure of tissue/organ surface and serves as a position marker of the sample but not the subsurface movement of blood flow and perfusion. A second wavelength is in the near Infra-Red (NIR) range, which has much deeper penetration. This wavelength reveals the underlying blood flow physiology and correlates both to the motion of the sample and also the movement of blood flow and perfusion. Thus, true motion of blood flow and perfusion can be derived from the NIR imaging measurement without being affected by the motion artifact of the target.

An esophageal electrode structure (6) measures electrical characteristics within an esophagus and a position determination unit (34) determines the position of the esophageal electrode structure within the esophagus and the position of the surface of the heart (5).

Since for measuring the electrical characteristics the esophageal electrode structure (6) is used, the electrical characteristics can be measured within the esophagus and thus close to the surface of the heart (5), thereby allowing for an improved accuracy of determining the electrical characteristics on the surface of the heart (5).
