Abstract

Abstract A laser device particularly suitable for use in surgery includes a housing and a laser beam oscillation device elastically mounted within the housing. The laser beam oscillation device includes an elongated support stand which extends substantially vertically within the housing and through an opening in the top of the housing, and a laser beam resonator such as a CO 2 laser is mounted on the support stand to provide a laser beam having an optical axis. A laser beam transmitting arrangement is connected to the support stand coaxially with the optical axis of the laser beam. As a result of this construction, the laser device occupies significantly less floor area within an operating room, and can easily be moved about while maintaining optical alignment at all times.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 130 words
A laser device which comprises: a housing having a top end with a first opening in this top end; a laser beam oscillation device elastically supported in the housing; said laser beam oscillation device including: an elongated support stand arranged substantially vertically in the housing and having an upper end projecting through the first opening in said top end of said housing, said support stand having at least one axis of symmetry in its cross section perpendicular to its longitudinal axis; a laser beam resonator mounted on the support stand for providing a laser beam having an optical axis; and means for transmitting the laser beam emitted from the laser beam resonator, said transmitting means being connected to the support stand coaxially with the optical axis of the laser beam.
Claim 2
Dependent Claim 130 words
A laser device which comprises: a housing having a top end with a first opening in this top end; a laser beam oscillation device elastically supported in the housing; said laser beam oscillation device including: an elongated support stand arranged substantially vertically in the housing and having an upper end projecting through the first opening in said top end of said housing, said support stand having at least one axis of symmetry in its cross section perpendicular to its longitudinal axis; a laser beam resonator mounted on the support stand for providing a laser beam having an optical axis; and means for transmitting the laser beam emitted from the laser beam resonator, said transmitting means being connected to the support stand coaxially with the optical axis of the laser beam.
Claim 3
Dependent Claim 37 words
A laser device according to claim 1, which further comprises: lifting means within said housing for moving the support stand vertically in the housing; and a vibration absorber provided between the support stand and the lifting means.
Claim 4
Dependent Claim 30 words
A laser device according to claim 1, in which the support stand has at its upper end a second opening for passing the laser beam emitted from the laser resonator.
