APPLICATOR

摘要

An applicator is inserted into a living body and applies mixed solution to a region in the living body. The applicator includes a nozzle including an elongated nozzle main body to which gas and a plurality of kinds of liquids are supplied and a nozzle head at a distal end of the nozzle main body and configured to jet A mixed solution of the gas and the liquids supplied to the nozzle main body, and a sheath in which the nozzle main body is fitted for relative movement along a longitudinal axial direction of the nozzle main body. At least two crushed portions are provided contiguously to each other at a proximal end portion of the nozzle main body at the opposite side to the nozzle head such that deformation directions thereof with respect to an axial line of the nozzle main body are different from each other.

主权项

1. An applicator configured to be positioned in a living body, the applicator comprising:
a sheath possessing a lumen, and open distal and proximal ends communicating with the lumen of the sheath, the sheath also possessing an inner face surrounding the lumen; a nozzle including an elongated nozzle main body possessing proximal and distal ends, a spray head connectable to different kinds of liquids to be conveyed through the nozzle main body and mixed with one another, and a nozzle head, the spray head being fixed to the proximal end of the nozzle main body so that the nozzle main body and the spray head move together as a unit, the nozzle head being fixed to the distal end of the nozzle main body so that the nozzle main body and the nozzle head move together as a unit, the nozzle head possessing a distal end at which is located an opening through which the liquids mixed together as a mixed solution are ejected together with a gas, the nozzle main body being axially movably positioned in the lumen of the sheath; the applicator being insertable into a living body to apply the mixed solution to a region in the living body; the nozzle main body including an axially extending first portion at which the nozzle main body is deformed in a first deformation direction relative to a portion of the nozzle main body axially adjacent the first portion so that an outer circumferential part of the axially extending first portion of the nozzle main body contacts the inner face of the sheath while the portion of the nozzle main body axially adjacent the first portion is spaced from the inner face of the sheath; the nozzle main body including an axially extending second portion at which the nozzle main body is deformed in a second deformation direction relative to a portion of the nozzle main body axially adjacent the second portion so that an outer circumferential part of the axially extending second portion of the nozzle main body contacts the inner face of the sheath while the portion of the nozzle main body axially adjacent the second portion is spaced from the inner face of the sheath; the first and second portions of the nozzle body being located axially contiguous to one another and at a proximal end portion of the nozzle main body; and the first and second deformation directions being different directions.
