| 121 | Medical or dental handpiece head | US11545980 | 2006-10-10 | US08197253B2 | 2012-06-12 | Norbert Schatz; Alois Gollackner |
| Described herein is a medical or dental handpiece head having a head sleeve detachably connected by a screw or threaded connection to a closing cap, and a locking device for locking the closing cap with the head sleeve. The locking device between the closing cap and the head sleeve is formed by at least one spring element. The locking device is designed and arranged so that unintentional release of the screw connection between the closing cap and the head sleeve caused by vibrations during operation of the handpiece can be suppressed. | ||||||

| A dental tool displacement apparatus for use with a motorized power handle to displace a dental tool includes a tool holder having a receptacle for receiving the dental tool, and a drive arrangement. The drive arrangement defines a transmission from the motorized power handle to the tool holder such that the tool holder undergoes reciprocating motion parallel to the tool axis at a first frequency of oscillations per minute and rotates about the tool axis at a second frequency of rotations per minute. In some cases, the two types of motion are generated by an eccentric drive pin engaging an annular slot which has gear teeth along one side, thereby generating an angular rotation step of the tool holder during each reciprocating stroke. In some cases, the first frequency is at least one order of magnitude greater than the second frequency. | ||||||

| A medical or dental handpiece has a grip 3. The grip 3 includes first to third rotation shafts 101, 201, and 301. The first and second shafts are connected through a first gear mechanism 1000 and the second and third shafts are connected through a second gear mechanism 2000 so that a rotation is transmitted from the first shaft through the first gear mechanism to the second shaft and then from the second shaft through the second gear mechanism to the third shaft. The first or second gear mechanism has an internal gear secured on shaft and an external gear secured on the other shaft, the internal and the external gears being engaged with each other. The external gear is substantially enclosed within a cylindrical plane 1001, 2001 extending along a peripheral edge of the internal gear. | ||||||

| 126 | IMPLANT ERECTING DRILL TOLL, HAND-PIECE, ADAPTOR FOR THE HAND-PIECE, AND SURGICAL GUIDE | US12733472 | 2008-07-31 | US20100185201A1 | 2010-07-22 | Han-Joon Kim |
| An inventive implant handpiece (12) includes a head (14) having a round outer peripheral surface (20) which is concentric with a center axis of a drill bur (17) and has a predetermined length (H1 to H3) as measured axially of the drill bur (17). A surgical guide (11) has a guide hole (13) having a round inner peripheral surface to be opposed to the round peripheral surface (20) of the head (14). Since a drilling operation is performed with the head (14) fitted in the guide hole (13), the head (14) can be reliably uniquely guided to form an implant implantation hole as desired. Thus, the present invention provides an implant handpiece capable of accurately drilling a hole for formation of an implant implantation hole, and a surgical guide capable of guiding this handpiece. | ||||||

| Medical, in particular dental, contra-angle handpieces for driving a dental instrument connected to the contra-angle handpiece with shafts arranged in the contra-angle handpiece for the transmission of the drive movement to the instrument. In order to achieve a reduction of sound emission and a reduction of the manufacturing and assembly costs while still incorporating the curvature of the outer sleeve of the contra-angle handpiece and the advantages which this entails, the contra-angle handpiece is equipped with a single-piece shaft which is essentially centered at the proximal end and the distal end of the outer sleeve, but runs eccentrically in a section of the outer sleeve between the proximal end and the distal end. The curvature of the outer sleeve of the contra-angle handpiece is in the range of about 8° to about 16°, and in some implementations, in the range of about 10° to about 14°. | ||||||

| 137 | Dental handpiece | US10539741 | 2003-12-22 | US20060121413A1 | 2006-06-08 | Derek Turner |
| A dental handpiece is disclosed including a turbine construction creating a radial in flow of air onto the impeller blades about the whole circumference of the turbine. This generates additional torque and avoids asymmetrical thrust on the impeller wheel. A pair of axially spaced air bearings support the turbine. Air supply to the bearings is controlled in such a way that the air bearings are floated before drive air is supplied to the turbine and after drive air to the turbine has been shut off. This ensures that the air bearings are always operational irrespective of the operational state of the turbine. The handpiece has an improved ergonomic shape, especially the shape and configuration of the front or drive head, which provides additional tooth clearance and a better field of view. An angled swivel connection to the umbilical cord is provided which reduces physical strain on the dentist's wrist. A self adjusting lock and key type torque connection between the dental burr and the chuck is provided which accommodates both conventional burrs and the burr of the lock and key arrangement. An auto stop arrangement for the turbine is disclosed which prevents a vacuum buildup during run-down of the turbine. The specific construction of the auto stop valve in accordance with the invention closes both the drive and exhaust air conduits. | ||||||
