Definitions
- the invention relates to a method for the development and virtual testing of a surgical instrument, in particular a surgical hand-held device, preferably for use in ophthalmology.
- the present invention is therefore based on the object of specifying a method for the development and virtual testing of a surgical instrument, in particular a surgical hand-held device, preferably for use in ophthalmology, according to which there is the possibility of the developed hand-held device before building a prototype, especially but before a so-called pilot series, to test virtually.
- this is the combination of development and virtual testing of a surgical instrument, with improvements to the instrument acceptable through an iterative process.
- the developer for example a doctor,
- CONFIRMATION COPY a dialogue development program either by data medium or preferably made available online via the Internet, the program via a computer, preferably a PC, a notebook, laptop or the like. Can be used by the developer decentralized.
- the process implemented here forms the basis of a service facility for external product developers, in particular for product developers from operational practice.
- the method provides the external developer with the opportunity to formulate his new development-related idea in the free text with reference to the known prior art, in particular with reference to an already existing existing handset, possibly from the range of the provider of the method according to the invention in a particularly advantageous manner via a predetermined input mask happens.
- the user of the method has the ability to make a drawing, wherein the developer input tools are offered, namely in particular for making a technical drawing, possibly with the involvement of a drawing relating to the prior art, can be built on.
- the developer makes an input to the provider, whereupon a processing of the input or the transmitted information takes place.
- the processing can be automatic or at least semi-automatic, provided that the transmitted information is machine-readable.
- the processing of the input takes place at least with the cooperation of a development / design expert or a development team, up to the creation of a perfectly formed pure drawing, which can preferably be carried out computer-animated 3D animated.
- the finished drawing such as the 3D animated drawing of the development object, is sent back to the developer in a next step, preferably also via the Internet, in particular as an e-mail attachment.
- a VPN connection is established, so that the coupled computer of the inventor communicates directly with the central computer of the provider.
- the developer gets the preferably 3D-animated drawing for viewing, so that the developer can express change requests in the function and in the design.
- the developer makes a repeated input, likewise via the input mask in the sense of a "correction input".
- the - initially virtual - developed handset is integrated into a virtual training program, namely on the part of the provider.
- This training program is available to the developer after incorporation of the self-developed handset, so that a virtual testing of the handset by the developer and / or by any third parties using the training program and a dummy handset is possible.
- the developer uses a handheld device having the basic functions of a corresponding handheld device or at least the basic design, this merely serving to "operate" the virtually developed handheld device in the 3D view, ie in the relevant operating field. Due to the course of the training and the result of the training, the developer has the opportunity to carry out further optimizations on the development object, whereby here again an iterative process for optimizing the handset based on the training results can take place. Only after the end of the test phase in the training program is released by the developer in relation to the virtually tested handset, so that at least a prototype, a pilot run or even a small series can be made.
- the method according to the invention thus offers a practice-oriented developer, for example a physician, the possibility of communicating his ideas or developmental object, for example an improved surgical hand-held device, to the operator of the method, iteratively optimizing the hand-held device and finally initiating a virtual test phase.
- a practice-oriented developer for example a physician
- the possibility of communicating his ideas or developmental object for example an improved surgical hand-held device
- the operator of the method iteratively optimizing the hand-held device and finally initiating a virtual test phase.
- a final test can take place, which ends with the release and ultimately with the production of at least one prototype.
- the Dialogue development program can offer the developer different input tools, for example for making a technical drawing in the sense of a 3D graphics, but above all including a drawing relating to the prior art, for example, patents or existing devices of the provider ,
- the claimed method comprises a virtual training program, quasi as a program / procedure module.
- This module includes a method for carrying out a virtual operation both for training purposes and for testing purposes with regard to the module according to the invention, in particular for performing a virtual ophthalmological intervention, the method being defined by an operating program and comprising various method steps, which via the computer, preferably via the developer's PC, by the developer decentralized, ie individually on the PC, abaillebar is. Interruptions or pauses are possible during the execution of the program.
- the module comprises the following process steps:
- the operation program is provided via a data carrier or via the Internet and can be downloaded and activated via an access authorization from the data carrier or via the Internet.
- the module integrated into the method according to the invention is based on the fundamental idea that any operations from a wide range of medical disciplines can be performed virtually by the developer, for which purpose a specific surgical field on the human or animal body, for example the surgical field of an eye, is displayed. Specifically, this may be the display of a PC or a laptop / notebook.
- a cataract operation can be simulated on the human eye, such a virtual specific intervention being carried out with at least one dummy that has been developed in virtual fashion and is mimicked by a specific medical operating device that is in the developer's possession.
- the dummy or the movement and the operation of the dummy are computationally projected into the surgical field, whereby methods are used, as for example from the publications DE 102 57 624 A1, DE 102 57 625 A1, DE 10 2007 023 506 A1, DE 10 2007 057 208 A1 and EP 1 025 520 B1, are known per se.
- the methods shown there are advantageously applicable here, whereby EP 1 025 520 B1 also shows, inter alia, a device which can be used in the sense of the hand-held device described here as a dummy with the required basic functions.
- a corresponding hand-held device for carrying out a virtual operation is known per se from DE 10 2007 045 875 A1.
- the operation program is provided via a data carrier made available to the developer or via the Internet and can be loaded from the data carrier or downloaded via the Internet on the basis of an access authorization and activated accordingly.
- the dummy is a specific medical operating device, if necessary with apparatus peripheral for operating the operating device.
- the dummy may be a counterfeit footswitch used in ophthalmic surgery to operate the handset or to drive the peripherals to power the handset.
- the dummy is connected to the PC via a cable and a USB interface, similar to how the actual handset is connected to a drive supply unit.
- the handset and / or the foot switch simulate at least the basic functions of the genuine - virtually developed - device, the operation program on a corresponding operation and responds to a handling of the handset and the relevant geometric data into the simulation and thus adapts the operating situation.
- the surgical field and the dummy are displayed animated 3D, it being conceivable that the representation in the view, in particular in the viewing angle, is changeable.
- the operation can be followed from different perspectives and perspectives, especially under the operating surgeon's perspective.
- the individual operation steps can be logged, it being further conceivable that the entire course of the operation and possibly the result of the operation are automatically analyzed and communicated to the developer.
- the surgical program serves as a guide to a specific operation, after which the individual surgical steps are instructed visually and / or by voice, as desired. So it is conceivable, for example, that individual operation steps are analyzed by the operation program and then modeled by the developer. A linguistic instruction on the individual operation steps away is also conceivable.
- the developer can be notified of improvement suggestions regarding the individual operation steps from the operation program.
- the entire record of the virtual operation is transmitted to a central computer.
- the virtual operation is - from the outset - stored on the central computer and can - at the option of the developer - evaluated by an over the service provider of the operation program provided expert - at the same time, timely or delayed and be commented. Again, suggestions for improvement regarding the handset and the operation may be made.
- the specifically simulated operation can be, for example, a cataract operation on the human eye.
- the type of virtual operation can be selected by the developer from an input menu, whereby a selection of operation types is made available, such as the ophthalmologist having various types of operations to be carried out on the human eye and corrections of various types poor eyesight.
- the access authorization to the operation program is provided via a hardware protection, preferably via a dongle to be attached to the PC. Regularly such a dongle is connected via a USB interface to the computer, as well as the dummy. It is of very particular advantage if the dummy is assigned to the hardware protection or a dummy can be implemented, so that with the coupling of the dummy one or more specific virtual operations - automatically - unlocked.
