Patent number: 9949803Abstract: Medical or dental instruments having a lighting device, manufacturing methods for such instruments and various lighting devices having an optical semiconductor element are described. The lighting devices have, for example, a body, at least one radiation-emitting surface on a radiation-emitting end of the body and at least one fluid channel which is provided in the body and connects at least one opening which is provided on the radiation-emitting end to one or more fluid sources for dispensing fluid. The lighting devices have, for example, a hollow metallic sleeve, a transparent window for emission of electromagnetic radiation and a socket on which at least one optical semiconductor element is arranged. The socket is made of a ceramic, glass ceramic or glass material, and is connected to the hollow metallic sleeve by a material comprising metal and glass.Type: GrantFiled: January 17, 2014Date of Patent: April 24, 2018Assignee: W&H Dentalwerk Bürmoos GmbHInventors: Christoph Heinrich, Thomas Jindra

Patent number: 9532851Abstract: A quick stop drilling tool for use with a medical or dental treatment device includes a drilling tool having a body extending between a connection end and a working end and having a longitudinal extension along a longitudinal axis of the drilling tool. The drilling tool has a hollow outer shell in which a probe is held that can be moved along the longitudinal axis so that a part of the probe can be moved out of the shell through an opening. The probe is designed as an elongated pin, and its first end facing the connection end is held in the interior of the hollow outer shell. An electromagnetic sensor for detecting relative movement between the shell and the probe is arranged along the longitudinal extension of the body. The drilling tool has a channel for a treatment fluid extending along the longitudinal axis.Type: GrantFiled: March 27, 2014Date of Patent: January 3, 2017Assignee: W&H Dentalwerk Bürmoos GmbHInventors: Christian Pruckner, Thomas Jindra, Georg Watzek, Ewald Unger

Patent number: 9333019Abstract: A driver for medical wires has a hollow drive shaft, rotatable about a rotation axis. The hollow drive shaft has a distal end and a proximal end. Furthermore, a plurality of clamping jaws penetrates under an angle into the hollow drive shaft close to its distal end. The clamping jaws are moved into or out of the hollow drive shaft by means of a jaw guide mounted slidable parallel to the rotation axis and movably connected to the clamping jaws. An actuator is provided to shift the jaw guide parallel to the rotation axis and therefore modify the penetration depth of the clamping jaws.Type: GrantFiled: March 15, 2013Date of Patent: May 10, 2016Assignee: Arthrex, Inc.Inventors: Rudraksh Khosla, G. Scott Sherman, Thomas Jindra

Patent number: 6916176Abstract: A rotation locking device located in the area of two separate, independent shafts or shaft sections for preventing the undesired rotation of a shaft or shaft section. The rotation locking device includes a locking pin which, in its idle position (during operation of the appliance), rests on a displacement surface of a shaft or shaft section. In the event of the undesired rotation of a shaft (caused, for example, when a tool is being unscrewed from a coupling which is connected to the shafts), the shaft underneath the locking pin turns until the pin is forced out of the displacement surface, is displaced outwards radially and pressed against a component which is fixed to the body of the appliance (e.g. the bearing sleeve of the gearbox in which the rotation locking device is fitted). Any further rotation of the shafts is prevented in this manner.Type: GrantFiled: September 2, 2003Date of Patent: July 12, 2005Assignee: W&H Dentalwerk Burmoos GmbHInventors: Norbert Schatz, Thomas Jindra
