In a probe for observing an ultrasonic image, which obtains the ultrasonic image of an object to be observed such as a body cavity by means of an ultrasonic transmitting and receiving means, a mechanical scanning operation of the ultrasonic transmitting and receiving means is performed by an ultrasonic driving means, and thus it is possible to obtain a good diagnosis image with no distortion and no flicker because noises of the driving means can be reduced.Therefore, an ultrasonic endoscope system and an ultrasonic video endoscope system etc. which utilize the probe mentioned above can display a good ultrasonic image and a good optical image.

In an endoscope, a curvature indicating element for curvature-indicating a curvable curvature section provided adjacent to a distal end of an elongated inserting section having elasticity is arranged at a location close to a thumb of a hand grasped by an operator in the operating section provided at a proximal end portion of an inserting section. An operating element for controlling operation of fluid such as outflow, inflow or the like is arranged at location opposite to the curvature indicating element in the operating section. Thus, operations of the curvature operation, outflow and inflow of the fluid and the like can be executed simultaneously under a condition where the operating section is grasped.

An endoscope apparatus according to the present invention includes a warping velocity control device which receives an angle of warp detected by an angle detection device and a value of an electric current realized at this angle of warp and detected by an electric current detection device. The control device makes comparisons between the angle of warp and the value of the electric current and data about a normal state stored in a storage device. If the result is larger than data for the normal state by a predetermined value, the warping velocity is lowered while a discrimination is made that an abnormal state (the warp-enabled portion has come in contact with the body wall) takes place. Additionally, the apparatus could include a time detecting device for detecting a time in which an electric quantity supplied to a drive means is larger than a predetermined time. The warping velocity control device controls the warping velocity according to the comparison made by the time detecting device.

A curvature section provided in an insertable section is curved in response to a curving instructing signal output by the operation of a curving operating switch. In case the curving operating switch is of a joy stick type having an operating lever, in response to the operation of a switching switch, a mode in which the inclination angle of the operating lever is held and a mode in which the inclination angle of the operating lever is returned to a neutral position in which it is zero will be switched and the curvature section will be of a curvature angle following the inclination angle of the operating lever.In case the curving operating switch is of a joy pad type comprising a plurality of on/off switches, in response to the operation of the switching switch, the curvature instructing signal will be held or reset.

At least one controlling unit of a controlling unit for controlling a bending driving motor bending driving a bendable portion, a controlling unit for controlling an advancing and retreating driving motor advancing and retreating moving an insert section and a controlling unit for controlling a rotating driving motor rotating driving the insert section and a camera controlling unit for processing a signal for an imaging device are made separate from each other so that such existing scope as an electronic scope or fiber scope fitted with a TV camera may be used.
摘要:
An endoscope system having a cover type endoscope provided with an elongate inserting section having therein an observation device and an illuminating device and bulge portions formed on the outer periphery at the side of a forwardmost end of the inserting section; and an endoscope cover having an endoscope inserting passage for covering and protecting the inserting section. The endoscope inserting passage receives the inserting section using the bulge portions as a guide. The bulge portions project more than the outer periphery of the inserting section.
