Aims: develop a distance regulator for the Er:YAG laser. Methods: metallic device adaptable to 2051 handpiece was developed. Interchangeable pieces, with diferent lengths, are regulator's body. Results: this laser allows standard distances delivering, from 08 20 millimetres target tissue. Conclusions: use of new evaluation effects in experimental surgery, when emitted different

Methods: LSSR was conducted employing two different laser systems: a) CO2 laser, articulated arm with nasal hand-piece / wave guide, or b) 980nm diode laser with fiber delivery system. The surgical technique includes direct transmucosal ablation of anterior or posterior cartilaginous spurs without incisions, mucoperichondrial flaps, therefore eliminating the need for post-op packing. The laser ...

The new arc lamp-based Palomar MaxG handpiece (Palomar Medical Technologies, Inc., Burlington MA) is designed for the treatment of vascular lesions and pigmented lesions in Fitzpatrick skin types I-IV (Fig. 1). The device employs optical spectral filtering and lamp voltage control to optimize treatment of blood vessels over a wide range of diameters and depths, while reducing the heating of the...

This paper presents a reciprocating air microcompressor with a piston diameter of 1 mm. A microcompressor construction is proposed aiming at simple fabrication with lots of space for installing inlet and outlet ports. The inlet port of the microcompressor does not have a moving valve, while the outlet port is equipped with a miniature reed valve. The compression process was numerically modelled...
