Patent ID: 8677990

Claim:
An endo-tracheal intubation device comprising: a stylet comprising: a stylet tubular element having a stylet distal end and a stylet proximal end opposite said stylet distal end, a stylet channel extending through said tubular element from said stylet distal end to said stylet proximal end, and a scored section proximate said stylet distal end, said scored section comprising a plurality of spaced apart transverse slots positioned along and extending into one side of said stylet tubular element; a stylet holder comprising: a stylet holder distal end and a stylet holder proximal end opposite said stylet holder distal end, a cavity extending into and within said stylet holder distal end of said stylet holder, said cavity sized so as to receive said stylet proximal end of said stylet, a U-shaped channel along said stylet holder proximal end, and a through passageway extending from said cavity into said U-shaped channel, a bell crank pivotally connected to said stylet holder proximal end, said bell crank comprising: a short arm positioned so as to pivotably move within said U-shaped channel, and an elongated trigger arm disposed at an obtuse angle to said short arm, said elongated trigger arm being pivotably movable towards and away from an outer surface of said stylet holder; and a flexible wire comprising: a continuous wire having a first wire end and a second wire end opposite said first wire end, said first wire end being connected to said stylet, and said second wire end being connected to said short arm, said flexible wire extending through said stylet channel along said scored section, beyond said stylet proximal end into said stylet holder and through said through passageway so as to connect said stylet to said short arm; wherein movement of said elongated trigger arm towards said outer surface of said stylet holder causes said stylet to bend along said scored section, and wherein said cavity of said stylet holder comprises (i) a first cavity portion at said stylet holder distal end, (ii) a second cavity portion between said first cavity portion and said through passageway, said first cavity portion having a greater cross-sectional area than said second cavity portion, (iii) a first shoulder between said first cavity portion and said second cavity portion, and (iv) a second shoulder positioned between said second cavity portion and said through passageway.
