An instrument head including an exit opening (), a first feed line () for feeding a first fluid, a second feed line () for feeding a second fluid, and a reservoir () for storing the second fluid fed via the second feed line () is disclosed. The reservoir () is in fluid communication with the first feed line () and/or is adapted to be brought in fluid communication with the first feed line () via at least a valve () arranged in the instrument head, to deliver the second fluid stored in the reservoir () via the exit opening ().

Methods for injecting fluids

A preparation instrument comprising an HF-instrument with an electrode that is partially insulated by means of an insulating body, which is combined with a fluid applicator having a channel arranged in the insulating body for the application of a fluid to or into tissue. In some embodiments of the preparation instrument, the electrode is a spatula electrode which is inserted in the insulating body that does not cover sections of the surface of the electrode so that these sections may be in contact with the tissue. The insulating body preferably forms the channel wall that delimits the channel. The insulating body and the electrode may be flexible in order to adapt the form of the insulating body and the electrode, together, to the surgical task.

HF-surgical preparation instrument with fluid channel

The invention relates to a method for mixing at least two fluids using an externally mixing nozzle for medical purposes, which has at least two outlet channels () and at least two inlet openings () with different or identical cross-sections, wherein two fluids with different volumetric flows and/or different viscosity are sprayed, and wherein the ratio of the cross-sections of the inlet channels () and/or the outlet channels () corresponds to the ratio of the volumetric flows so that the fluids flow with substantially identical flow speeds through the outlet channels () and/or the inlet openings (). The invention furthermore relates to an externally mixing nozzle, a medical instrument and a medical device for spraying substances, in particular biological material.

Method and nozzle for mixing and spraying fluids

The invention relates to a supply system having at least one outlet for connecting to an applicator instrument, and having a controller () that controls at least one valve ('&#x2033;) such that, within an application time interval of less than 4 s, in particular less than 2 s:

Supply system for creating a pulsed fluid jet, application system having supply system and control process for operating a supply system

The invention relates to an instrument head, comprising: an exit opening (); a first feed line () for the feed of a first fluid; a second feed line () for the feed of a second fluid; a reservoir () for storing the fluid fed via the second feed line (); wherein the reservoir () is in fluid communication with the first feed line () and/or is adapted to be brought in fluid communication with the first feed line () via at least a valve () arranged in the instrument head, to deliver fluid stored in the reservoir () via the exit opening ().

Instrument head, application instrument having said instrument head, application system and method of operating a supply system

A nozzle for the supply of biological material, in particular tissue cells, having a mixing chamber () which is delimited by a proximal end surface () and a distal end surface () spaced apart from the proximal end surface (), at least one nozzle opening () which is formed in the distal end surface (), and at least two supply ducts () which discharge into the mixing chamber (). A first supply duct () is arranged in the proximal end surface () and discharges into the mixing chamber () coaxially to the nozzle opening () and a second supply duct () has an inlet opening () which discharges into the mixing chamber () laterally, in particular tangentially at the distal end surface ().
