Abstract
In order to improve a surgical appliance comprising a housing having at least one sealed cavity, and a drive unit arranged in the housing, such that the cavity can be sealed in a simple way, and the formation of germs can be reduced or these can be removed in a simple way from the cavity, it is proposed that a fluid connection be provided for forming a flow path into and out of the cavity, and that at least one sealing element be provided for closing the fluid connection to liquid fluids and opening the fluid connection to gaseous fluids.
Claims19
Surgical appliance comprising:
- a housing having at least one sealed cavity,
- a drive unit arranged in the housing,
- a fluid connection for formation of a flow path into and out of the cavity, and
- at least one thermally activatable sealing element adapted to close the fluid connection to liquid fluids and open the fluid connection to gaseous fluids;
- wherein:
- the surgical appliance comprises a tool used in surgery;
- and
- the at least one thermally activatable sealing element adapted to automatically open the fluid connection to said gaseous fluids at temperatures which equal or exceed an activation temperature.
Surgical appliance comprising:
- a housing having at least one sealed cavity,
- a drive unit arranged in the housing,
- a fluid connection for formation of a flow path into and out of the cavity, and
- a gas-permeable membrane which is impermeable to liquid fluids for sealing the fluid connection against liquid fluids while permitting the flow of superheated steam into and out of the cavity.
Surgical tool, comprising:
- a housing having at least one sealed cavity,
- a drive unit arranged in the housing,
- a fluid connection for formation of a flow path into and out of the cavity, and
- at least one thermally activatable sealing element adapted to close the fluid connection to liquid fluids and open the fluid connection to gaseous fluids comprising superheated steam;
- wherein the at least one thermally activatable sealing element opens the fluid connection to said gaseous fluids at temperatures which equal or exceed an activation temperature.
