Length-measuring device and reference color display device for color tone adjustment for use in combination with endoscope
First Claim
1. A length-measuring device for use with an endoscope, comprising:
- (a) a tube having a first slit formed therein and a second slit formed therein and disposed rearwardly of said first slit, said tube being bendable at each of said first and second slits, and said tube further having a length-measuring portion extending forwardly from said first slit to a distal end of said tube; and
(b) means for bending said tube at said first and second slits.

Abstract
A length-measuring device comprises a flexible tube having a first slit and a second slit disposed rearwardly of the first slit, said tube being bendable at each of the first and second slit, and said tube further having a length-measuring portion extending forwardly from the first slit to a distal end of said tube; and means for bending said tube at the first and second slits. Typically, the bending means is a wire which has a connection relation with the length-measuring portion to pull the same. The length-measuring portion is coated with regularly arranged scale marks. After being projected from a forceps channel of an endoscope, the length-measuring portion is pulled to assume a T-shape. The length-measuring portion can be disposed at the center of a field of vision of the endoscope, and also can be easily brought into intimate contact with a target affected part. In a reference color display device, the length-measuring portion is replaced by a distal end portion coated with three primary colors.

-
(a) a tube having a first slit formed therein and a second slit formed therein and disposed rearwardly of said first slit, said tube being bendable at each of said first and second slits, and said tube further having a length-measuring portion extending forwardly from said first slit to a distal end of said tube; (b) means for bending said tube at said first and second slits; and (c) a core rod inserted into said tube from a proximal end of said tube and extending to a position near said distal end of said tube, whereby when said core rod in said tube is passed past said first slit toward said distal end of said tube, said tube can not be bent at said first and second slits, and when said core rod is retracted past said second slit toward said proximal end of said tube, said tube can be bent at said first and second slits. - View Dependent Claims (39, 40, 41, 42, 43, 44, 45, 46, 47)
