Description

The invention relates to a method for controlling an ophthalmic surgical device system, which comprises a console which has at least one computing device and at least one graphic display device, at least one surgical hand-held device being operable and deliverable by the device system, in particular with overpressure and / or underpressure and / or Ultrasonic power and / or liquid and / or light and / or electromagnetic energy and / or electrical energy. Furthermore, the invention relates to such an eye surgery device system.

Eye surgery device systems of the type in question have been known in practice for years. These are used to carry out ophthalmic operations, for example phacoemulsification. A lens clouded by a cataract is smashed using an ultrasound needle. The lens debris is aspirated through the needle. In order to avoid collapse and overheating of the eye, an irrigation fluid is supplied to the eye during the procedure. Thus, the surgical handheld device is to be supplied with ultrasound power, irrigation fluid and a negative pressure through the console during the procedure.

It is also conceivable that the ophthalmic device system is used to perform a vitrectomy. Here, a hand-held device designed as a mechanical cutter is inserted into the eye. To operate the handheld device, it is supplied with compressed air pulses. Furthermore, the cut vitreous tissue is sucked out of the eye. Thus, the surgical handheld device must be supplied with compressed air pulses and with negative pressure.

Further possible interventions which can be carried out with such a device system can be, for example, diathermy, for example blepharoplasty, an intervention with laser light, an oil injection etc.

Corresponding ophthalmic surgical device systems thus offer a multitude of possible uses which go hand in hand with a correspondingly high number of setting options or parameters which have to be set and monitored during operation of the device system. An incorrect setting must be avoided at all costs, since the eye is an extremely sensitive organ, so that slightly serious injuries or even blindness can occur if it is handled incorrectly.

The present invention is therefore based on the object of specifying a method for controlling an eye surgery device system, in which a safe and error-free control is made possible in a simple manner. Furthermore, an eye surgery device system for performing such a method is to be specified.

• - Auswahl des gewünschten Benutzerprofils,
• - Anzeige mindestens eines dem ausgewählten Benutzerprofil zugeordneten Operationsprofils innerhalb eines zweiten Darstellungsmoduls auf der Anzeigeeinrichtung, wobei dem Operationsprofil mindestens ein vordefiniertes Operationselement zugeordnet ist,

• - Auswahl eines Operationselementes, wobei der mindestens eine Grundparameter eingestellt bzw. berücksichtigt wird.

According to the invention, the above object is achieved in procedural terms by the features of claim 1. According to this, the method in question for controlling an ophthalmic surgical device system that comprises a console that has at least one computing device and at least one graphic display device, wherein at least one surgical handheld device can be operated and supplied by the device system, in particular with overpressure and / or underpressure and / or ultrasonic power and / or liquid and / or light and / or electromagnetic energy and / or electrical energy, the following process steps:

• Displaying at least one user profile within a first display module on the display device, the user profile being assigned at least one operation profile,
• - selection of the desired user profile,
• Display of at least one operation profile assigned to the selected user profile within a second display module on the display device, at least one predefined operation element being assigned to the operation profile,
• - selection of an operation profile,
• Display of at least one operation element assigned to the operation profile within a third display module on the display device, at least one basic parameter of the device system being assigned to the operation element,
• - Selection of an operating element, the at least one basic parameter being set or taken into account.

It is pointed out that the term “controller” is to be understood in the broadest sense, in particular the operation of the device system.

The term “ultrasound power” is to be understood to mean that it is possible to operate the handheld device in such a way that the distal end is excited to an ultrasound oscillation. For example, a current and / or a voltage can be made available in order to set piezo elements arranged in the handheld device in vibration.

The term “liquid” includes in particular oil and irrigation liquid, for example a saline solution. The term “light” also includes visible light for lighting and laser light. The term “electrical energy” describes, for example, electrical current and / or electrical voltage, with which in particular a hand-held device for lighting or a hand-held device for diathermy can be supplied. Furthermore, the device system can provide "electromagnetic energy", for example for the operation of an electromagnetic vitrector.

Furthermore, the handheld device can be part of the device system, although this is not necessarily the case.

In the manner according to the invention, it was first recognized that the control or operation of the device system can be made considerably simpler and more secure by having different user profiles for the users of the device, operation profiles being assigned to the individual user profiles. For example, in the case of several surgeons, each surgeon can specify the operations that he carries out with the device system. For example, user A only performs phacoemulsifications, whereas user B performs phacoemulsifications and vitrectomies. After the device system has been switched on, which can be done, for example, via a preferably capacitive or inductive switch, the user who is using the device system at this time will be selected from the user profiles displayed within a first display module before performing an operation. The display device can be, for example, a monitor or display. Alternatively or additionally, a mobile display device, in particular in the form of a remote control, can be provided, for example a smartphone, a tablet computer or a PDA (Personal Digital Assistant).

The operation profiles assigned to this user profile are then displayed in a second display module. As already stated above, the operation profiles can be, for example, phacoemulsification, vitrectomy or any other ophthalmological intervention. Furthermore, it is conceivable that, depending on any indication of the patient, several different surgical profiles are provided, for example an emulsification of the natural lens of different degrees of the diagnosed cataract. Depending on how hard the lens core to be removed is, the surgeon can select the surgical profile in which the surgical elements or surgical steps and the basic settings are based on the indication, i.e. the nature of the lens are matched.

In another manner according to the invention, each operation profile of the respective user is assigned operation elements, in particular operation steps. After the selection of an operation profile, for example a phacoemulsification, the operation elements stored for this user, that is to say operation steps, are displayed in a third display module.

In a further manner according to the invention, basic parameters for controlling or operating the device are specified for the selected user in the selected operation profile and the selected operation element. In particular, these can be maximum values of the essential operating parameters or basic parameters.

The method according to the invention makes it possible, in a particularly simple manner and thus avoiding incorrect settings, for the ophthalmic device system to be operated with the basic parameters preferred for a specific operation and by a specific operator.

It is conceivable that a standard user profile is provided in the first display module, to which at least one operation profile, in particular the operation profiles of all operations that can be carried out with the device system, are assigned with at least one safe standard basic parameter. The standard user profile can preferably not be deleted. If, for example, a user profile has been accidentally deleted, the surgeon can select the standard profile to carry out the intervention.

In a particularly advantageous manner, the first, the second and the third display module are displayed simultaneously on the display device. This makes it possible for the device system to be parameterized in a particularly simple and reliable manner.
Furthermore, it is conceivable that after the selection of the operation element, the at least one basic parameter is displayed in a basic parameter display module on the display device. It is thereby achieved that the information to be recorded by the user is reduced to a minimum, namely only the basic parameters necessary for the execution of the operation element or operation step are shown.

In order to enable simple operation, the selection of the user profile, the operation profile, the operation element and / or a change in the basic parameter setting could take place via a display device designed as a touchscreen. Furthermore, it is possible for the display device to enable multi-touch control or gesture control and / or for the display modules to be displaceable, in particular by means of multi-touch control or gesture control. Alternatively or additionally, the selection could be carried out via a foot switch coupled to the console. In a particularly advantageous manner, the foot switch could be battery-operated or battery-operated and could communicate with the console wirelessly, for example via Bluetooth.

In a further advantageous manner, the foot switch can comprise a pedal and possibly several buttons. The pedal could be actuated along the longitudinal axis, that is, forwards and backwards. Furthermore, it is conceivable that the pedal is designed to be rotatable and possibly comprises a plurality of side buttons. The buttons could be implemented as rocker switches. In a further advantageous manner, the functions which can be actuated by the pedal could be changed via the console, that is to say the assignment of the pedal could be adapted.

According to an advantageous development of the method according to the invention, the device could be initialized after a selection of the surgical element, for example a hose connection connected to the device system could be filled with fluid and / or a surgical hand device connected to the console could be subjected to a function test and / or a detection of the Ultrasound time are reset and / or an irrigation source is connected. For this purpose, an initialization module, preferably simultaneously with the basic parameter setting module (s), could be displayed on the display device and selected by the user, so that the necessary initializations can be displayed and selected.

The basic parameters that are assigned to the operational elements of the user profile of a specific user can be an ultrasound power and / or a cutting rate of a vitrector and / or a vacuum and / or a flow rate and / or a heat output and / or is a light output. Alternatively or additionally, it could be a pressure and / or a laser power and / or a laser pulse duration and / or a duration of a laser pulse pause and / or an intensity of a target beam. The aiming beam initially enables the surgeon to use visible light of relatively low intensity to indicate the area of the tissue on which the laser light that is actually to be used will fall. For example, the target beam can be visible laser light of low intensity, the device system being able, for example, to switch from the laser light serving as the target beam to the laser with which the actual intervention is carried out.

To further improve simple control and handling of the ophthalmic device system, each basic parameter preset for an operating element could be displayed in a separate basic parameter display module during the execution of the operating element or operating step. As an alternative or in addition, it is conceivable that interrelated basic parameters, for example a laser power and a laser pulse duration, are displayed in a common basic parameter display module.

To optimize manageability, a maximum value of a basic parameter could be changed or changed during the execution of an operation element, for example via a display device designed as a touchscreen or via a foot switch coupled to the console. For example, the maximum ultrasound power could be increased by the user or surgeon while the operation element is being carried out if the lens core is particularly hard, possibly contrary to the original assumption.

According to a further embodiment, it is conceivable that the user profile and / or the operation profile and / or the operation element can be newly created, deleted and / or changed.

In order to ensure a particularly safe function of the device system, the function of the device system could be monitored, for example via one or more sensors, and in the event of a malfunction, a corresponding error message could be displayed on the display device. Specifically, the possible malfunctions could be divided into at least two different degrees of severity and the presentation of the error message depending on the severity could be adjusted. For example, if the charge level of the foot switch battery falls below a predefined state of charge, a “slight” error message could be given that the foot switch battery is to be charged. If the state of charge of the battery or the battery of the foot switch falls below a minimum value, a "severe" error message could be displayed, prompting the user to charge the battery or to establish a connection to an external power source. The degrees of severity could be color-coded, for example green for a clear indication, yellow for an easy-to-correct fault and red or blue for a serious malfunction.

To further improve handling, the error message could be displayed in the basic parameter display module relating to the malfunction. For example, if the voltage on an ultrasound handle is too high, a corresponding error message could appear in the basic parameter display module of the ultrasound power.

According to a particularly advantageous embodiment of the method according to the invention, an operation report could be stored on a storage medium during and / or after operation of the device system. The operation report could include, for example, the user profile, the operation duration, the operation profile, the ultrasound duration and / or any error messages.

The underlying object is further achieved by an ophthalmic surgical device system which, according to claim 15, serves to carry out the method according to the invention.

It is pointed out that the method according to the invention also has features in terms of the device that can be implemented by the device system according to the invention and expressly form part of the disclosure described here. The ophthalmic surgical device system according to the invention can thus have the features described above and in the following description of the figures with regard to the method.
