Abstract: A medical instrument comprises an interface for electrically connecting a drive unit with the medical instrument. The interface has a plurality of electrical contacts arranged in a connecting surface. At least one of the contacts in the connecting surface is electrically isolated from the remaining contacts by a recess or an elevation.

Abstract: A membrane switch assembly for a handpiece for carrying out medical interventions includes a ring-like support surrounding a support interior, and a keypad element arranged on the support and intended to be actuated in order to carry out switching procedures. The keypad element is secured on the support so as to close the support interior in a fluid-tight manner. On an outer circumferential side of the ring-like support, a sealing arrangement surrounds the ring-like support.

Abstract: The invention relates to a medical instrument for removing tissue, in particular a shaver, drill, or morcellator, having a tool that can be set in rotation and a motorized drive for driving the tool, and having an elongate body and a handle that projects laterally from said elongate body. The handle is fastened in a detachable manner to the body.

Abstract: A drive unit for a rotatable high-frequency electrode of a medical resector for cutting, ablating, or coagulating human or animal tissue includes an engine device for generating a rotation movement and a coupling device for transmitting the rotation movement generated by the engine device to an axis coupled with the rotatable high-frequency electrode when the drive unit is coupled with the medical resector. The drive unit is configured to provide on the coupling device a rotation frequency in a range from 10 rpm to 200 rpm.

Abstract: A medical resector for oblating, cutting, or coagulating human or animal tissue includes a rotatable high-frequency electrode on the distal end of a shaft of the medical resector and an axle that runs from the proximal end to the distal end of the shaft and is mechanically coupled with the high-frequency electrode on the distal end. The axle is positioned on the distal end of the shaft in the center or as close as possible to the center of the cross-section of the shaft and on the proximal end of the shaft on the border or as close as possible to the border of the cross-section of the shaft.
