Patent number: 9101337Abstract: The invention relates to a surgical coupling system which comprises first and second surgical coupling devices each having at least two electrical coupling contacts that are moveable mechanically into engagement with one another. The coupling devices are completely separated from each other in a separated position and are mechanically in engagement with one another in a mechanical coupling position. The system further comprises an electrical switching device which, in the coupling position, is moveable from an OFF position, in which at least one first electrical coupling contact of the first coupling device and at least one first electrical coupling contact of the second coupling device are out of engagement, into an ON position in which the at least one first electrical coupling contact of the first coupling device and the at least one first electrical coupling contact of the second coupling device are in electrically conductive contact or engagement.Type: GrantFiled: October 8, 2013Date of Patent: August 11, 2015Assignee: Aesculap AGInventors: Roland Hoegerle, Martin Machill, Ralf Pfister

Patent number: 8241235Abstract: In order to improve a surgical DC power tool such that it can be operated, where applicable, under sterile conditions, in particular, using conventional DC voltage supplies, a surgical switch mode power supply for a surgical DC power tool is provided. The switch mode power supply includes a switch mode power supply circuit arrangement, a switch mode power supply housing and a circuit receptacle formed in the housing of the switch mode power supply for accommodating the circuit arrangement of the switch mode power supply. The housing of the switch mode power supply has a switch mode power supply interface which is designed in such a manner that it can be brought into engagement with and/or connected to an interface of the DC power tool provided for a mains-independent energy source. Furthermore, an improved surgical DC power tool having such a power supply is provided.Type: GrantFiled: May 12, 2009Date of Patent: August 14, 2012Assignee: Aesculap AGInventors: Thomas Kahler, Roland Hoegerle

Publication number: 20080118234Abstract: To improve a surgical machine with a sensorless electric motor comprising a rotor and at least two motor windings, and with a motor controller for controlling and/or regulating the electric motor, so that the electric motor is operable with optimum efficiency at low rotational speeds and a starting of the motor in accordance with the purpose, also under load, is enabled, it is proposed that a space vector pulse width modulation (SVPWM) method for controlling and/or regulating the electric motor, in which all motor windings are able to be simultaneously supplied with electric current, be performable with the motor controller. A method for controlling and/or regulating a surgical machine is also proposed.Type: ApplicationFiled: January 22, 2008Publication date: May 22, 2008Applicant: AESCULAP AG & Co.
