Description

The invention relates to a supply device for at least one medical instrument and to a method for configuring a corresponding supply device.

Numerous cryosurgical and electrosurgical instruments have been used in medical operations in recent years. For example, in high frequency surgery (HF surgery), high frequency alternating current is passed through the human body to selectively damage tissue. Thus, many conventional medical instruments, such as the classic scalpel, are being replaced by modern devices that are powered and controlled by appropriate care facilities. In the field of high frequency surgery, for example, an RF generator must be connected to a corresponding electrosurgical instrument to provide a suitable alternating current. In cryosurgery, utilities are used that are in fluid communication with appropriate instruments (eg, cryoprobes or ablation probes) and provide fluid to cool the instrument. It is obvious that the corresponding utilities must have arithmetic units for controlling respective actuators and control and display units to allow interaction with the user.

The display units provide the user with information regarding the supply device and the connected instrument. The information displayed here is often specified by the manufacturer of the utility. The users of such systems (supply device with instrument) often have very different requirements with respect to the display unit and the usability of the system. So there are doctors who rely heavily on the information displayed and want a very detailed presentation here. Other physicians use the systems almost like traditional instruments and rely on their experience and visual control during the course of treatment to assess the situation. It is problematic for manufacturers to provide systems that meet the needs of all users.

The WO 2009/086008 A1 describes a supply device for controlling and monitoring a laser, which is preferably used in eye surgery. According to the WO 2009/086008 A1 it is possible for the user to set a color change of the display device individually. This color change may, for example, relate to the set power level of the laser.
