Abstract
The invention relates to a medical, in particular dental-medical handpiece (3) having a rod-shaped grip part in the forward end region of which there is arranged a holding device (5) having a lateral insertion opening (13) for a working tool (6), whereby the middle axis (5a) of the insertion opening (13) includes, with the middle axis (3c) of the grip part extending rearwardly from the point of intersection with the middle axis (5a), an obtuse angle (W2). In order to improve the suitability of the handpiece (3) also for use in small spaces of the body to be treated, a forward grip section (3b) of the grip part is curved towards the side (14) of the handpiece (3) away from the insertion opening (13), and the obtuse angle (W2) is smaller than 103° and greater than 95°.
