  • Patent number: 11771461
    Abstract: The present application provides a passive holding device for handling a trocar and a modular surgical system. The passive holding device has a fastening device with a coupling portion. A pivoting mechanism is connected to the coupling portion via a rotary joint. The pivoting mechanism has two L-shaped branches arranged parallel to one another, each having a short leg that is connected to a long leg via a pivot joint. The short leg of the first branch is longer than the short leg of the second branch and is connected to the long leg via a rotary shaft. The trocar holder has a gripping device and has an instrument brake. A tilting brake is arranged at the coupling portion, operatively connected to the rotary joint, and a pivoting brake is arranged at the coupling portion operatively connected to at least one of the terminal pivot joints.

  • Patent number: 11324561
    Abstract: A remote manipulator system according to the invention for carrying out manipulations in a body-internal cavity comprises a manipulator apparatus with a motor-driven actuator mechanism for moving at least two endoscope apparatuses that are insertable through a respective access opening into the body-internal cavity, said endoscope apparatuses each having an elongate shaft (3), wherein the at least two endoscope apparatuses are each displaceable along a longitudinal direction and pivotable about a pivot point (10) defined by the respective access opening, an operating apparatus (21, 71) with at least two control elements (22, 22?, 22?, 33, 72, 72?, 72?, 73), which each have an elongate shaft (23, 23?), wherein the at least two control elements (22, 22?, 22?, 33, 72, 72?, 72?, 73) are each, in manual fashion, displaceable in the direction of a longitudinal axis and pivotable about a pivot point (30), and a controller (75) which is embodied to detect a respective longitudinal displacement and pivot movement of t

  • Patent number: 11141235
    Abstract: An autoclavable handle (5) includes a handle housing (9) and with at least one switch element (11) mounted to the handle housing (9). The autoclavable handle (5) is permanently resistant to the effects of machine cleaning and of steam sterilization. The at least one switch element (11) is resiliently pressable into the handle housing (9). The switch element (11) is mounted in the handle housing (9) via at least one web (16) arranged on an underside of the switch element (11). The switch element (11) is sealed off from the handle housing (9) via a circumferential sealing element (12).

  • Publication number: 20210113297
    Abstract: The present application provides a sensor-based surgery set and a method for determining the position of a holding device for a surgical instrument. The surgery set includes at least one holding device, an initialization station, and a number of sensors. The initialization station has a number of sensor slots, wherein each sensor is assigned to one sensor slot and wherein the initialization station is coupled to a storage unit in which initialization information is assigned to each sensor slot. A number of sensor slots are arranged on the holding device, wherein each sensor slot is assigned to one sensor slot of the initialization station. In an initialization arrangement, a specific number of sensors is in engagement with the sensor slots of the initialization station and are coupled to the storage unit for initialization and data transmission. In use, however, the sensors are in engagement with the sensor slots.
