摘要： A dental handpiece stably cutting a wall of a root canal without a fear of piercing a root opening. The dental handpiece includes a means for holding a tool cutting a tooth to be cured and a support for setting the cutting tool at a desired position relative to the tooth to be cured. The length of the support may be changeable by stages. The holding means may be formed of a head of the dental handpiece and a plurality of supports with different lengths may be removably mounted to the head. The support can stand on a head of the dental handpiece and the length from the head is changeable. The support is formed separately from the dental handpiece to be removable, and may have a stopper which abut with a tooth to be cured or an appropriate portion near the tooth.

摘要： A stainless steel bur, which can cut minute depressions etc. and even healthy dentin when necessary, allowing a technician to detect when cutting the healthy dentin is provided. It includes a removable handle (11) connected to a hand piece on the base side, a working section (12) to which a cutting blade for cutting teeth is attached to the tip, and the working section and the handle are connected to a tapered intermediate section (13). This steel bur is formed into a fiber structure by hardening austenitic stainless steel through wire drawing. Since the tapered part bends and generates vibrations when the working section is rotated to cut healthy dentin, it can be understood that the healthy dentin is being cut, and excessive cutting may be prevented. Alternatively, excessive cutting may be prevented by processing from the maximum diameter of the working section to the tip thereof through etching or the like to round cutting blade edge and make a blunt edge.

摘要翻译： 一种不锈钢毛刺，可以在必要时切割微小的凹陷等甚至健康的牙本质，允许技术人员在切割健康的牙质时检测。 它包括连接到基座侧的手持件的可拆卸手柄（11），用于切割齿的切割刀片附接到尖端的工作部分（12），并且工作部分和手柄连接到锥形 中间部分（13）。 该钢坯通过拉丝硬化奥氏体不锈钢而形成纤维结构。 由于当工作部分旋转以切割健康牙本质时，锥形部弯曲并产生振动，因此可以理解，健康牙本质被切割，并且可以防止过度切割。 或者，可以通过从工作部分的最大直径到其尖端通过蚀刻等加工成圆形切割刀刃并且形成钝边来防止过大的切割。

摘要： This invention serves to solve the problem of the large irradiation angle upon an observation target of an inclined illuminator type medical binocular microscope, and the problem of structural complexity and light attenuation of a coaxial illuminator type microscope. The microscope A includes the illumination system 2 comprised of the illumination unit 6 with the condensing lens 6d attached at a front tip of the illumination unit, disposes the illumination system retaining member 7 in close proximity to the two observation optical systems structured at the body tube 3, defines the plane 8 including the prescribed lenses of the objective lenses of the left and right observation optical systems 1 (secondary objective lens 1b) arranged closest to the observation target, and arranges the optical axis 2a of the illumination system 2 inside the circle 9 having a diameter connecting the optical axis 1a of the two observation optical systems with respect to the plane 8. The optical axis 2a intersects with the optical axis 1a of the observation optical system 1 at the observation target surface 4a.
