An endoscope system includes a movement detector for detecting an operator's movement, a signal processor for processing a signal the detector detects, and a control for controlling drive which drives a medical device according to an output signal of the signal processor. The endoscope system bends a bending section of an endoscope serving as a medical device according to the operator's movement, and thus orients the observation field of view to a direction the operator intends or controls the movement of a treatment adapter serving as a medical device. The endoscope system includes a superimposing means for superimposing an image associated with the operator's movement onto an image acquired by an imaging device associated with the endoscope system.

Endoscope system with automatic control according to movement of an

A medical system has a detecting device for detecting three dimensional image information about a living body, a signal processing circuit for processing the image signal transmitted from the detecting device, and an object information reproduction device. The object information reproduction device comprises a movable displacement element which is touched by the operator and acts according to the output from the signal processing circuit so as to cause the operator to tactually sense information about the object. Thus, the operator is able to recognize the degree of unevenness in a tactile manner by touching the displacement element. Other embodiments include means for sensing and reproducing hardness and temperature of the object.

Medical system having object information reproduction means for palpation

A medical system according to the present invention comprises a medical apparatus including an operation unit manipulated by a surgeon and a treatment section formed away from the operation unit for treating a subject, a detector or a pressure sensor for detecting a state of contact between the subject and the treatment section, and a reproduction mechanism for amplifying a small contact pressure according to the output of the detector and thus reproduce the state of contact so that the surgeon can perceive the state of contact.

Medical system for reproducing a state of contact of the treatment

An apparatus for holding an insertable part of an endoscope positioned in a combustion chamber of a reciprocating engine or rotary engine having ignition plug holes to observe the interior of the combustion chamber and an inspecting method are provided with a holding apparatus for stationarily holding the insertable part in the combustion chamber through a spark plug hole provided in the engine to insert a spark plug for a spark plug ignition into the combustion chamber.

A photo-pulse from a photo-pulse generating apparatus is branched, where one branch is radiated to an examined body and the reflected light reflected within the examined body is delayed in time in proportion to the depth from the surface of the examined body and is led to a time-analyzing reflected light measuring apparatus. In this measuring apparatus, the other branched reference photo-pulse or reference signal pulse is input as delayed by the time for which the photo-pulse reflected within the examined body returns and only the reflected light component synchronized with the entering timing of this reference light pulse is analyzed in the time and is detected. By varying the detection sensitivity of this measuring apparatus in response to the depth from the surface of the examined body, the interior can be observed.

Examined body interior information observing apparatus by using

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.

Endoscope

Disclosed is an industrial endoscope system having a rotary treatment member, attached to a hard top part at a distal end of an insertion unit, for effecting a treatment such as grinding by rotating this treatment member itself. The system includes a moving means for making a distal end of the treatment member movable in the axial directions of the insertion unit. This easily leads the treatment member to a target position via a lead-in port of an engine; or the treatment member can be set in a position suitable for the treatment.

A borescope apparatus comprising a flexible insertion section, a jet port formed at the insertion section, a moving device for supplying a compressed fluid to the jet port, whereby the insertion section is moved by an impellent force of the fluid ejected from the jet port, and a stabilizing device for steadily maintaining the position of the insertion section.

Borescope apparatus

A radioactive ray detecting endoscope comprises an elongated insertable part having an observing window in the tip part, an imaging apparatus converting an image of an observed part obtained through the observing window to an electric signal and a radioactive ray detecting apparatus detecting radioactive rays from inside the visual field of the imaging apparatus. The imaging apparatus has, for example, a solid state imaging device imaging an optical image of an object. Also, a collimator regulating the radioactive ray detecting direction is provided, for example, around the radioactive ray detecting apparatus.

A borescope apparatus comprises an insertion section having a bending portion and a flexible portion, a bending mechanism for bending the bending portion under the pressure of supplied fluid, a pressurized fluid supplying unit for supplying the fluid to the jet port and the bending mechanism and a flow control unit for controlling the fluid supplied to jet ports which are provided in the distal end of either the bending portion or flexible portion and the bending mechanism.

An ultrasonic treating apparatus includes an inpedance detection unit for detecting the impedance of an ultrasonic vibration element for transmitting ultrasonic vibrations and a determining unit for determining whether the ultrasonic vibration element is good or not. If the ultrasonic vibration element is found not to be good, then a control unit inhibits ultrasonic vibrations from being generated from the ultrasonic vibration element. It is thus possible to prevent any breakage of the apparatus.

A borescope apparatus having a borescope and a pressurized fluid supply device. The borescope has an operation unit and an insertion unit. The insertion unit comprises a bending tube portion, a jet port member coupled to a proximal end of the bending tube portion, and a flexible tube portion. The bending tube portion can be bent by operating the operation unit. The jet port member has a jet port. A pressuring fluid is supplied from the fluid supply unit to the jet port member, and is ejected through the jet port. The flexible tube portion can be bent by a jet of the fluid from through the jet port independently of the bending tube portion.
