Pneumatically actuatable surgical instrument

摘要

In a pneumatically actuatable surgical instrument comprising a handle and a pressurized gas operated tool arranged at the handle, a replaceable pressurized gas reservoir and a locking device for fixing the pressurized gas reservoir on the handle in an operative position in which the pressurized gas reservoir is connected to a pressurized gas channel by which the tool is supplied with pressurized gas, it is proposed, in order to improve the handling of the pressurized gas reservoir, that the instrument further comprises an unlocking device for releasing the fixing of the pressurized gas reservoir in the operative position.

1. A pneumatically actuatable surgical instrument, comprising:
a handle, a pressurized gas-operated tool arranged at the handle, a replaceable pressurized gas reservoir, a locking device for fixing the pressurized gas reservoir on the handle in an operative position mechanically preventing removal of the pressurized gas reservoir, the locking device being pneumatically activatable by pressurized gas of the pressurized gas reservoir, and an unlocking device for releasing the fixing of the pressurized gas reservoir from the operative position, wherein: in the operative position, the pressurized gas reservoir is connected to a pressurized gas channel by which the tool is supplied with pressurized gas, the unlocking device comprises a vent device which upon actuation of the unlocking device is movable from a rest position to a first operative position in which the pressurized gas channel is connected to a vent opening, and the unlocking device is movable from the first operative position to a second operative position in which the locking device is inactive and the pressurized gas reservoir is released for replacement.
