Laser-type handpiece
First Claim
1. A laser-type handpiece wherein a laser beam transmitted from a laser source to a handpiece body is refracted at a head section, said laser-type handpiece is characterized in that said handpiece comprises a reflector holding member and an applicator holding member pivotally connected to said head section via a pivot shaft, a control sleeve fitted over the external circumference of said body so that said sleeve can be moved back and forth along the axis of said body, and a slide member which is connected to an upper section of said reflector holding member and an upper section of said applicator holding member via connection points and is provided in said body so that said slide member can slide along the axis of said body, and is interlocked with the back-and-forth movement of said sleeve, whereby said reflector holding member and said applicator holding member are turned around said pivot shaft by sliding said slide member interlocked with the back-and-forth movement of said sleeve and the change of angle of said applicator holding member is approximately twice as large as that of said reflector holding member.

Abstract
A laser-type handpiece including a reflector pivotably connected inside a head section and a control sleeve which is connected to the reflector and fitted over the external circumference of the handpiece body so that the sleeve can move back-and-forth along the axis of the handpiece body, whereby the reflector can be adjusted to any desired angle by the back-and-forth movement of the sleeve. When this handpiece is used for dental treatment, the head section of the handpiece can be smoothly inserted into and taken out from a narrow oral region and the angle of laser beam can be changed easily.
