Abstract:
Disclosed is a high speed turbine dental handpiece suitable for disposable safe use, comprising a head (1) and a handle (2) connected to a rear end of the head (1), and further comprising a socket connector (3) provided on a rear end of the handle (2), and further comprising a clamp ring (4) for fixing the handle (2) and the socket connector (3). A first fixing groove (5) is provided on a side wall of the socket connector (3). A second fixing groove (6) cooperating with the first fixing groove (5) is provided on an end of the handle (2). A lug (7) cooperating with the first fixing groove (5) and the second fixing groove (6) is provided on an inner wall of the clamp ring (4). When the clamp ring (4) is wrapped around the socket connector (3), the lug (7) is embedded in the first fixing groove (5) and the second fixing groove (6), so as to limit and fix the handle (2) and the socket connector (3). Thereby the re-utilization of the disposable dental handpiece is effectively avoided by means of various ways. The present invention is simple in structure and convenient to disassemble, and can be disassembled and destroyed conveniently after use, and by using a disposable light-emitting assembly, it can be easily seen whether the dental handpiece is used, thereby effectively solving the problem of iatrogenic cross infection in the dental field.
