摘要： The distal end of an insertion section of an endoscope is divided into a plurality of segments each including a pair of SMA coils which are arranged symmetrically with respect to an axis and memorize a close-winding shape. As the SMA coils recovers their memorized shape, the distal end of the insertion section is bent. The SMA coils are restored to the memorized shape when they are conductively heated by means of a current supply circuit. The current supply circuit comprises an input unit for inputting a target value of the bend angle for a leading segment, a sensor for detecting the distance of insertion of the insertion section, a detector circuit for detecting the bend angle of each segment, and means for controlling the amount of current supply so that the bend angle of the SMA coils agrees with a target angle. The inputted angle is set as the target angle for the leading segment, and the detected bend angle of each segment is set as the target angle for each succeeding segment. The set value is renewed each time the insertion distance of the insertion section attains a predetermined distance.

摘要： Provided on the side of a distal end of an insertion part are an observation ultrasonic transducer for acquiring an ultrasonic image and a therapeutic ultrasonic transducer for outputting a therapeutic ultrasonic wave so as to be focused. Positioning or the like between the observation ultrasonic transducer and the therapeutic ultrasonic transducer is so conducted that a focusing point at which the therapeutic ultrasonic wave is focused is locked to a predetermined position within a scanning range of the observation ultrasonic wave. If the position of the focusing point is locked whereby a lesion part to be treated is set to a predetermined position on an ultrasonic image, it is necessarily possible to conduct the position setting to the focusing point. It is also made possible to confirm the position of the lesion part and to acoustically observe a state of the lesion part during irradiation of the therapeutic ultrasonic wave.

摘要： An endoscope includes a bending member having a shape memory alloy. A pair of heating current supplying wires and a pair of resistance detecting wires are connected at one end to the ends of the shape memory alloy. The other end of the heating current supplying wire is connected to a current supply circuit, and the other end of the resistance detecting wire is connected to a resistance detector. The resistance detector is constituted by a bridge circuit having a branch opened and the shape memory alloy is connected in the opened branch via the resistance detecting wires. A controller controls the current supply circuit according to the detected resistance. The current supply is effected by supplying a current pulse, and the amount of heating current and the bending degree can be controlled by controlling the pulse width of the current pulse. Since no heating current is supplied to the resistance detecting wires, the resistance thereof is not changed even when the shape memory alloy is heated by passing a heating current therethrough. Therefore, it is possible to precisely detect variation in the resistance of only the shape memory alloy member and measure the bending degree of the bending member.
摘要翻译：内窥镜包括具有形状记忆合金的弯曲构件。一对加热电流供应线和一对电阻检测线在一端连接到形状记忆合金的端部。加热电流供给线的另一端与电流供给电路连接，电阻检测线的另一端与电阻检测器连接。电阻检测器由具有分支开口的桥接电路构成，并且形状记忆合金经由电阻检测线连接在开启的分支中。控制器根据检测到的电阻来控制电流供应电路。通过提供电流脉冲来实现电流供应，并且可以通过控制电流脉冲的脉冲宽度来控制加热电流和弯曲程度。由于没有向电阻检测线供应加热电流，所以即使形状记忆合金通过加热电流而被加热，其电阻也不会改变。因此，可以精确地检测形状记忆合金构件的电阻的变化并测量弯曲构件的弯曲度。

摘要： A bending drive member to bend a bending member is arranged to extend in the direction of length of an elongate tube having flexibility, and attached to near the distal end of the tube with the distal end of the bending drive member being restricted in its position. The bending member drive member comprises a shape memory member formed by bundling together a plurality of wire-like shape memory materials each having a length, that spans from the position of one end to the other end, reversibly changed upon heating/cooling. The length of the shape memory member is changed dependent on a drive signal from a unit with a capability of heating. A non-compressive coil sheath through which the bending drive member extends is fixed at a distal end thereof to the elongate tube while the proximal end of the coil sheath is a free end with respect to the elongate tube.

摘要： An endoscope comprises an insertion section, and this insertion section has a distal end portion, a proximal end portion, and a bendable portion located between the distal and proximal end portions. A fluid-pressure actuator is coupled to the insertion section, so as to bend the bendable portion. The fluid-pressure actuator is made up of an extensible body and an expansion-restricting member. The extensible body defines an internal space and has an extension axis along which it extends or contracts. The expansion-restricting member causes the extensible body to extend in the direction of the extension axis when a fluid is supplied into the internal space, and causes the extensible body to contract in the direction of the extensible axis when the fluid is discharged from the internal space. The bendable portion of the insertion section is bent in accordance with the extension or contraction of the extensible body.

摘要： The position controlling apparatus of this invention is to curve an endoscope insertable part or a catheter and is provided with an actuator having a shape memorizing alloy body. The shape memorizing alloy body is heated or cooled by a driving appartaus and the actuator is displaced by such heating or cooling. The difference between the actual displacement of the actuator driven by the driving apparatus and the objective displacement of the actuator is output by a comparing means which operates the driving apparatus on the basis of this difference. A resistance value detecting circuit detects the resistance value of the shape memorizing alloy body varying when the shape memorizing alloy body is heated or cooled. The detected value detected by the resistance value detecting circuit is input into a controlling apparatus which controls the driving apparatus on the basis of the detected value and the preset used temperature range of the shape memorizing alloy body.
