Abstract
Abstract A dental handpiece arranged to perform dental work in the mouth by means of laser energy, the handpiece including a bundle (2) of optical fibres (3) leading to a face (5A) of a head (5). A water/air supply tube (4) leads to an outlet (6) adjacent to the head. In use, the laser beams are focussed at a point (9) where the dental work is performed, the point (9) being adjustable relatively to the head (5) and being able to be de-focussed. A probe (8) is provided to guide the operator during use.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
22 words
A dental handpiece characterised in that it is arranged to perform dental work in the mouth by means of a laser beam.
Claim 2
Dependent Claim
22 words
A dental handpiece characterised in that it is arranged to perform dental work in the mouth by means of a laser beam.
Claim 3
Dependent Claim
36 words
A handpiece as claimed in claim 1, characterised by at least one optical fibre (3) through which a laser beam can be transmitted, the optical fibre ending in an outlet face (5A) of a head (5).
Claim 4
Dependent Claim
23 words
A handpiece as claimed in claim 2, characterised in that a plurality of said optical fibres (3) is provided in a bundle (2).
Claim 5
Dependent Claim
30 words
A handpiece as claimed in claim 3, characterised in that said bundle (2) is spiralled to enable the head (5) to be pivoted relatively to the rest of the handpiece.
Claim 6
Dependent Claim
34 words
A handpiece as claimed in claim 3 or 4, characterised in that said optical fibres (3) are arranged around said head (5) and are angled downwards and inwards towards a cutting focus point (9).
Claim 7
Dependent Claim
27 words
A-handpiece as claimed in claim 5, characterised by means to adjust the focus point (9) and to de-focus it to give a cutting length of desired depth.
Claim 8
Dependent Claim
24 words
A handpiece as claimed in any one of claims 2 to 6, characterised in that said head (5) has a tactile probe (8). -
Claim 9
Dependent Claim
32 words
A handpiece as claimed in any one of claims 2 to 7, characterised in that a water/air supply tube (4) is provided, said tube terminating at an outlet (6) of the handpiece.
Claim 10
Dependent Claim
34 words
A handpiece as claimed in any one of claims 2 to 8, characterised in that a further optical fibre is provided to give a visual feedback to the operator of the operation being performed.
Claim 11
Dependent Claim
22 words
A handpiece as claimed in any one of the preceeding claims, characterised by a laser source for the operation of the handpiece.
