Abstract

Abstract A translaryngeal tracheostomy device having a trocar (11) inserted into an inter-annular space of the trachea, a traction wire (20) inserted into the trocar to move the end of the trochar outside of the oral cavity, a tracheostomy tube (30) with a substantially conical end (40, 55) into which the traction wire is inserted, a fiber optic device (6), and an expansion device (60) fixed to the end of the traction wire to insert the tracheostomy tube in the trachea. A traction guide tool (70) is also disclosed.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 173 words
Apparatus for producing a translaryngeal tracheostomy, comprising: a trocar (11) that can be inserted in an interannular space of the trachea, from the outside inward; a traction wire (20) which can be inserted in said trocar to move the end of the wire so as to extend outside the oral cavity; a tracheostomy tube (30) which is provided with a substantially conical end (40) into which said end of said traction wire which is outside the oral cavity can be inserted; characterized by an enlargement means (61) for preventing disengagement of the traction wire (20) from said tracheostomy tube (30) which means (61) can be fixed to said end of said traction wire (20) aimed to be moved outside the oral cavity after said end has been inserted in said tracheoscomy tube (30) whereby said tracheoscomy (30) can be pulled into the trachea and to make it exit from said interannular space from the inside outward by means of traction applied to said traction wire (20) from the end opposite said tube (30).
Claim 2
Dependent Claim 56 words
Apparatus according to claim 1, characterized in that it comprises a rigid cannula (1) which is provided with an inflatable sleeve (2) for inserting a bronchoscope (6), said rigid cannula (1) being arrangeable so as to indicate said interannular space with its free end by transillumination with the beam of light projected by said bronchoscope (6).
Claim 3
Dependent Claim 39 words
Apparatus according to claim 1 characterized in that said tracheostomy tube (30) further comprises a tubular element (31), which has an inflatable sleeve (32) at one end and has a penetration element (35) at the other substantially conical end.
Claim 4
Dependent Claim 53 words
Apparatus according to claim 3 characterized in that said inflatable sleeve (32) is connected to an air supply tube (32a) which can be accommodated inside said tubular element (31) and can be extracted, when the penetration end of said tubular element (35) exits from the trachea, to connect it to a pumping element.
Claim 5
Dependent Claim 53 words
Apparatus according to claim 3, characterized in that said penetration element (35) further comprises a fixed cone (40) which is placed at the end of said tubular element, (35) a flexible cone (41) being associated on said fixed cone (40), and ending with a penetration tip that is constituted by a metal insert.
Claim 6
Dependent Claim 31 words
Apparatus according to claim 3, characterized in that said penetration element (35) is constituted by a single rigid cone (40) which is arranged at the end of said tubular element (31).
Claim 7
Dependent Claim 37 words
Apparatus according to claim 3, characterized in that said penetration element (35) is constituted by multiple cones (55) which have progressively larger dimensions and are arranged sequentially with respect to said traction wire (20) that links them.
Claim 8
Dependent Claim 47 words
Apparatus according to claim 1, characterized in that said enlargement means (61) are constituted by a first retainer (60) which is fixed directly to the end of said traction wire and can be inserted in said trocar, a cup-like element (61) being applicable to said first retainer.
Claim 9
Dependent Claim 30 words
Apparatus according to claim 8, characterized in that it further comprises an elastic ring (62) which can be interposed between said first retainer (60) and said cup like element (61).
Claim 10
Dependent Claim 37 words
Apparatus according to claim 1, characterized in that said enlargement means (61) is constituted by folding wire (20) into the shape of a letter U after its insertion into the tracheostomy tube (30) to prevent its extraction.
Claim 11
Dependent Claim 24 words
Apparatus according to claim 1, characterized in that said enlargement means (61) is constituted by a knot which is produced on said traction wire.
Claim 12
Dependent Claim 96 words
Apparatus according to claim 1, characterized in that it further comprises a tool (70) for pulling said traction wire (20), said tool (70) comprising a base body (71) which is provided with a plate (72) that can be rested at the outer surface of the trachea, said plate (72) forming a passage hole (73) for said penetration element (35), a guiding bar (75) extending from said plate (72) and ending with an abutment cross-member (76), a slider (80) being slidingly arranged on said guiding bar (75) and having means for fixing to said traction wire (20).
Claim 13
Dependent Claim 45 words
Apparatus according to claim 12, characterized in that said slider is further provided with grip hollows (81) for the fingers of the operator, said crossmember (76) being suitable to provide rest to the palm of the hand when applying traction to said traction wire (20).
