牙科用手持件
摘要：
本发明涉及一种牙科用手持件，特别是窥镜手持件，该手持件包括壳体(16)，该壳体设置有在周向方向上延伸的可变形的壁部分(26)。在该可变形的壁部分(26)的后面设置变形传感器(34)，该变形传感器可由压电薄膜形成。所述变形传感器(34)的输出信号由鉴别器监控，以在所述可变形的壁部分(26)达到预定的变形时起动图像摄影。
摘要（英）：

A dental handpiece, in particular a camera handpiece, has a housing (16), which is provided with a deformable wall portion (26) extending in the circumferential direction. Lying behind the deformable wall portion (26) there is a deformation sensor (34), which can be formed by a piezo film. The output signal of the deformation sensor (34) is monitored by a discriminator in such a way as to triggerthe recording of an image when a predetermined deformation of the deformable wall portion (26) is reached.
