摘要:
A powered surgical tool (30) with a housing (32) that contains a power generating unit such as a motor (34). A control module (40) is disposed in a shell that is mounted in the housing. The control module contains a control circuit (64) for regulating the actuation of the power generating unit. The power generating unit emits a signal representative of the operating state of the unit that is transmitted through the structural material forming the shell. Also internal to the control module shell is a sensor (74,76) that monitors the signal emitted by the power generating unit. This signal output by the sensor is applied to the control circuit. The control circuit, based on the sensor signal regulates actuation of the power generating unit. Wherein the power generating unit is a motor, the signal emitted is the magnetic field that varies with rotor position. The sensor monitors the strength of this field.

There is provided apparatus (301) for mixing contents of a receptacle, the apparatus comprising a rotary shaft (302) equipped at a proximal end with a connection for removable attachment to a means of providing rotation. The rotary shaft has a mixing element (303) fixedly connected at a distal end of the shaft opposite to said proximal end. The mixing element comprises at least two arms (304) at the distal most end of the shaft, a corkscrew neck (306) on the shaft and a collar (305) on the shaft positioned in between the at least two arms and the corkscrew neck. The at least two arms are configured in a first partially-open resting position and are moveable to a second fully-open operative position. The mixing element further comprises a blade (307) positioned across the shaft more proximally than the corkscrew neck.

Un appareil pour l'application au sol d'un produit de ragréage, caractérisé en ce qu'il comprend : - un support apte à être déplacé manuellement au sol par roulement de façon multidirectionnelle ; et - un réservoir porté par le support et apte à contenir un liquide formant produit de ragréage ; et - un dispositif de distribution en communication sélective avec une région inférieure du réservoir, le dispositif de distribution comprenant une série de lumières espacées horizontalement à travers lesquelles le liquide est susceptible de s'écouler par gravité. Cet appareil permet d'appliquer un produit de ragréage liquide en position debout, d'une façon particulièrement simple, fiable, économique et efficace. Il est peu fatigant pour l'opérateur.

A mixing bucket has a cylindrical sidewall with longitudinally separated lower and upper bucket rims defining a bucket interior volume. A laterally oriented bucket bottom spans the sidewall and separates the bucket interior volume into upper and lower bucket volumes. At least one aperture is located in the sidewall and provides substantially laterally oriented access between an ambient environment and the lower bucket volume. At least one laterally oriented channel extends from at least one aperture and is located within the lower bucket volume. An elongate anchoring structure has first and second anchor ends laterally separated by an anchor body. The anchoring structure engages the bucket by the anchor body being at least partially positioned within the channel. An anchoring force is exerted upon the anchoring structure while the anchoring structure is engaged with the bucket, and the anchoring force counteracts a mixing force being exerted upon the bucket.

Es wird ein Adapter für einen motorbetriebenen Rührer sowie Rührer und Rührerblock zum Vermischen flüssiger Proben in Mikro- und Milliliter-Reaktionsgefäßen vorgeschlagen. Der Adapter (1) ist ausgestattet mit einer Rührer-Kupplung (4), über die der Adapter (1) mit dem Rührer (8) verbindbar und zu einer Rotation antreibbar ist, mit einer Rührstab-Aufnahme (2), in die ein Ende eines Rührstabs (3) in axialer Richtung einführbar ist, wobei die Rührstab-Aufnahme (2) den Rührstab (3) im wesentlichen koaxial zur Rotationsachse des Adapters (1) ausrichtet, wobei der Rührstab (3) durch den rotierenden Adapter (1) in eine taumelnde Bewegung versetzbar ist, so dass der Rührstab (3) gleichzeitig eine erste Rotationsbewegung um die eigene Achse und eine zweite Rotationsbewegung um eine nicht-konstante Rotationsachse ausführt.

A method for mixing medical/surgical cement is disclosed. That method includes the steps of placing components forming the cement to be mixed in a container, the container having a mixing blade and actuating the mixing blade with a power tool so as to mix the components together. The actuation of the power tool is regulated by a control processor, wherein during actuation of the actuation of the power tool, the control processor is provided with an indication of the current drawn by the power tool and, based on the current drawn by the power tool, the control processor selectively adjusts the actuation of the actuation of the power tool.
