Abstract
Disclosed is a manual hand ratch reamer for a dentist, which is used for forming a cylindrical hole in an alveolar bone of a patient upon implementing a dental implantation surgery. The manual hand ratch reamer for a dentist comprises a front piece body, a rear piece body and a rotating driver which are connected one with another in a manner such that the rotating driver can be independently rotated with respect to the front piece body and the rear piece body. A reamer tip locking section of the rotating driver, to which a reamer tip is secured, includes a connection device which is connected to the rotating driver by passing through the inside of the front piece body. When the rotating driver is rotated with respect to the front piece body, the front piece body is prevented from being rotated.

A manual hand ratch reamer for a dentist, which is used for forming a cylindrical hole in an alveolar bone of a patient upon implementing dental implantation surgery, characterized in that the manual hand ratch reamer for a dentist comprises a front piece body, a rear piece body and a rotating driver which are connected one with another in a manner such that the rotating driver can be independently rotated with respect to the front piece body and the rear piece body;
- a reamer tip locking section of the rotating driver, to which a reamer tip is secured, includes connection means which is connected to the rotating driver by passing through the inside of the front piece body;
- and, when the rotating driver is rotated with respect to the front piece body, the front piece body is prevented from being rotated,
- wherein the front piece body is formed as a tubular segment, is gradually decreased in its diameter toward a front end thereof, and has, at the front end thereof, an end cap on which the reamer tip locking section is rotatably supported;
- and the front piece body and the rear piece body are inserted into a circumferential inner wall of the rotating driver in a manner such that they are rotatably supported by the rotating driver.
