Abstract
Abstract An energy irradiation apparatus for medical treatment of tissues through irradiation of energy including a long main unit, an emitting part, a power transmission member, a drive mechanism, a first engaging member, and a second engaging is disclosed. The emitting part is disposed moveably inside a distal end of the main unit for emitting energy transmitted to a distal side from a proximal side. The power transmission member is disposed moveable inside the main unit. The emitting part is mounted to a distal end of the power transmission member. The drive mechanism reciprocates the power transmission member in a longitudinal direction of the main unit. The first engaging member is provided inside the power transmission member for receiving a drive force from the drive mechanism. The second engaging member is provided in the drive mechanism for engaging removably with the first engaging member.

100 words
An energy irradiation apparatus as claimed in claim
1, further comprising a restricting mechanism, in which either one of the first engaging member or the
second engaging member has a hook with a substantially U-shaped
groove, the other one of the first engaging member or the second
engaging member comprises an indented narrow part, to which
the groove fits, and guide parts formed in a tapered shape
provided adjacent to the narrow part for leading the groove
to the narrow part, and said restricting mechanism restricts motion of the first
engaging member when leading the groove into the narrow part.

1, in which said power transmission member also serves as
a transmission member for transmitting the energy from the
proximal side to the distal side.
Claim 4
Dependent Claim
49 words
An energy irradiation apparatus as claimed in claim
3, further comprising a casing with a supporting part by which
the first engaging member is supported in such a way as to
make a reciprocating motion, in which said power transmission
member is stored in the casing making a loop.
Claim 5
Dependent Claim
16 words
An energy irradiation apparatus as claimed in claim
1, in which said energy is laser beam.

for reflecting the energy transmitted to the distal side from
the proximal side, said apparatus further comprising a guide mechanism having slide parts provided within
a range required for the reciprocating motion of the reflecting
part, and extension parts for tilting the reflecting part
further toward a direction parallel to an axis of said main
unit than it was engaged with the slide parts, and engaging
with a portion of the reflecting part slidably to change an
angle of the reflecting part as the reflecting part moves
in the longitudinal direction, and an operating part provided on the proximal side for moving
the reflecting part between a position where it engages with
the slide parts and a position where it engages with the
extension parts.
Claim 7
Dependent Claim
30 words
An energy irradiation apparatus as claimed in claim
6, in which said guide mechanism comprises connection parts

An energy irradiation apparatus as claimed in claim
6, further comprising a lumen formed inside said main unit,
in which an endoscope is disposed for observing vital tissues,
and a linking mechanism having a supporting part for supporting
the endoscope disposed in the lumen, in which said linking mechanism retracts the endoscope
toward the proximal side when a portion of the reflecting
part moves from the extension parts to the slide parts, and
moves the endoscope toward the distal side when the same moves
from the slide parts to the extension parts.
Claim 9
