Abstract
Abstract 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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
141 words
A medical system for diagnosing tactual information from an object which is not capable of being directly palpated, comprising: a medical device for visually diagnosing the state of the object; detecting means connected to said medical device for detecting three-dimensional information showing the unevenness of the object, further including imaging means for providing a three-dimensional image of a location of the object not normally accessible to direct contact for palpation; computing means operably connected to said detecting means for calculating a quantity of unevenness at a predetermined position on said image; and object information reproduction means operably connected to said computing means for reproducing said information showing the unevenness of the object at said predetermined position according to an output from said computing means so as to be sensed in a tactile manner by an operator who operates said medical device.
Claim 2
Dependent Claim
141 words
A medical system for diagnosing tactual information from an object which is not capable of being directly palpated, comprising: a medical device for visually diagnosing the state of the object; detecting means connected to said medical device for detecting three-dimensional information showing the unevenness of the object, further including imaging means for providing a three-dimensional image of a location of the object not normally accessible to direct contact for palpation; computing means operably connected to said detecting means for calculating a quantity of unevenness at a predetermined position on said image; and object information reproduction means operably connected to said computing means for reproducing said information showing the unevenness of the object at said predetermined position according to an output from said computing means so as to be sensed in a tactile manner by an operator who operates said medical device.
Claim 3
Dependent Claim
29 words
A medical system according to claim 1, wherein said object information reproduction means further comprises observing means for enabling the operator to visually observe the state of the object.
Claim 4
Dependent Claim
25 words
A medical system according to claim 1, wherein said medical device includes an endoscope device having a function of obtaining an image of the object.
Claim 5
Dependent Claim
31 words
A medical system according to claim 3, wherein said object information reproduction means further includes image position instructing means operated by the operator for selecting said predetermined position on said image.
Claim 6
Dependent Claim
48 words
A medical system according to claim 4, wherein said image position instructing means further includes a displacement element which can be touched by the hand of the operator and is capable of being displaced at least one dimensionally by a quantity which corresponds to said quantity of unevenness.
Claim 7
Dependent Claim
42 words
A medical system according to claim 5, wherein said object information reproduction means includes a magnification means for varying the magnification of the displacement when said displacement element is displaced by a quantity which is in proportion to said quantity of unevenness.
Claim 8
Dependent Claim
21 words
A medical system according to claim 3, wherein said endoscope device includes a pair of image pickup means for three-dimensional observation.
Claim 9
Dependent Claim
17 words
A medical system according to claim 4, wherein said image position instructing means consists of a mouse.
Claim 10
Dependent Claim
29 words
A medical system according to claim 1 further comprising display means for enabling the operator to confirm information of the object according to the output from said detecting means.
