Description

CENTRALIZED CONTROL DEVICE WITHOUT INTERMEDIATE, WITH OR WITHOUT CONTACT, OF DEVICES

REMOTE MEDICAL

The present invention relates to a control device without physical contact of medical devices, usable by the practitioner.

The conduct of an operation, requires the practitioner, the use of medical devices, surgical or not.

Many devices such as electrosurgical devices are indispensable instruments in particular to conduct many surgical operations. The environment of an operating room must meet stringent hygiene requirements and strict sterility conditions. During an operation, the surgeon can not have physical contact with the controls of the surgical or exploration instruments. In addition, certain delicate acts such as the destruction of a tumor cell are dependent on the communication between the surgeon and his assistant. Thus, to adjust the various medical devices during the operation, the surgeon must usually use an assistant to perform the necessary manipulations. The communication between the surgeon and the assistant is sometimes ambiguous and difficult as indicated by the document "A non-contact mouse for surgeon computer interaction" of C. Graetzel, T. Fong, S. Grange, and C. Baur, published in Technology and Health Care, 12 (3): 245-257, 2004.

Empowering the surgeon to control the setting or activation of the electronic devices in the operating room seems to be a real challenge in the course of an operation, so that the operator (surgeon or practitioner) is no longer tributary of a third person (dresser) for the control of medical devices.

Furthermore, devices using touchscreen screens are known, as for example mentioned in the article "An Approach for Projector-based Surgeon-Computer Interaction using Tracked Instruments" by Bojan Kocev, Darko Ojdani ^' c, Heinz-Otto Peitgen, published in Fraunhofer MEVIS Universitat Room 29, 28359 Bremen, Germany. Unfortunately, these do not provide 100% sterility (Kocev et al, 201 1). This type of device must be completed with a sterile cover to limit the risk of contamination and requires the surgeon to move away from the operating table to perform the necessary manipulations as is detailed for example in US4621735., For not be spared by the intervention of a helper or material

Other non-contact control devices are known by recognition of operating room gestures whose functions and uses are however more focused on the visualization of information on the patient and medical imagery via including access to the network Pictures Archiving and Communication Systems (PACS) during operation.

Thus, the device mentioned above, proposed by Kocev et al 201 1, uses an optical measurement system to follow the surgical tools on which a tracker is fixed and which are used to interact with the projected virtual interface. This system allows the surgeon to project the virtual interface in the flat sterile zone of his choice and thus to consult preoperative data or patient information. This device does not allow the surgeon to control the equipment of the operating room. Its use therefore does not allow to give autonomy to the surgeon and the proposed functionalities require the establishment of trackers making complex its use in medical interventional environment.

Similarly, the device mentioned above, proposed by Graetzel et al 2004, allows the aid of a stereoscopic camera system, the recognition of the movement of the hands, so that a surgeon is able to make a more efficient use of computers in medical intervention. This device offers the surgeon the ability to determine a capture space from which he can control the computer by the movement of his hands. To minimize the presence of screens, this device uses the endoscopy video monitor. This device does not fully meet the constraints of a medical intervention. Indeed, the surgeon must move to the stereoscopic column to be able to view the information on the computer and this device is only used for a certain type of medical procedures requiring the presence of the column stereoscopic.

The patent application WO2012129669 proposes a device for controlling electronic equipment for the purpose of displaying medical information on a display system, for example of the LCD type. This device uses a gesture recognition system such as Kinect® or Wavi Xtion® to control equipment for navigation within the PACS system. This device therefore requires the use of an LCD monitor which is binding in an interventional medical environment often already congested. This device also does not allow the control of the equipment of the medical interventional environment such as for example the operating table, the scalpel, or the operating light.

The patent application WO201 185815 proposes a control device, for example by detecting the movement of hands or an instrument, of a navigation system in a medical environment. The user's gestures make it possible to execute a set of commands such as the manipulation of displayed images or to control the software functions of a medical navigation system. This device offers to view the image on a monitor or to project it on a suitable background. At no time does this device respond to the problem of autonomy and sterility of the surgeon in terms of equipment settings of a medical interventional environment. There is therefore a need for a device allowing the surgeon to order himself, directly and without any intermediate person, all or part of the equipment ordered electronically in the operating room or in the intervention room, without the risk of non-sterile physical contact with any element whatsoever, thus solving the problems of the devices mentioned above.

The present invention therefore aims to remedy these drawbacks, by providing a control device without physical contact between the practitioner and the control of his instruments, and without necessarily having recourse to a third party.

For this purpose, the present invention relates to a device for remote control with or without contact, of at least one medical device, comprising:

at least one device for projecting a graphic interface on at least one reception surface,

at least one object locating device for detecting a movement of at least one object in at least one capture area, and

at least one communication device with at least one medical device, for transmitting, on detection of said movement, a predefined command to said at least one medical device. The device is further such that the at least one receiving surface is a physical surface separating a first operating space from a second operating space, the first operating space including at least one capture area.

By "medical device" is meant any electronic device suitable for use in a medical environment, both for effecting a modification of the physical state of a patient according to a predefined command of an operator, as for an exploration medical device made by a practitioner, such as an endoscope probe, or the access and display on the receiving surface of a patient's file to obtain information (antecedents, medical risks, allergies). .). By "modifying the physical state of a patient, is meant, in general, any modification of the functioning or the physical condition of a patient, in particular, and by way of non-limiting example, the use of a electrosurgical unit to open the patient's body, to cut or cauterize tissues, to destroy cells, in particular tumor cells, or to inject gas into the patient's abdomen to perform a laparoscopy, this list being of course in no way limiting and only given for information only. Advantageously, the medical devices will be surgical medical devices.

By "projection device" is meant a device capable of projecting existing information on a defined surface. The device may in particular be equipped with means for enlarging the image to be projected. Thus, preferentially, the projection device will be a video projector. Usually equipped with an objective part, it can be equipped with different optical systems, to adapt the projected information according to the distance between the projection device and the screen or to adapt the image to the color of the projection surface, to optimize contrast and visual rendering. In addition, the projection device may be adapted to use in a sterile room, and in particular, said device may not include a fan. The control device may be equipped with several projection devices. The projection device may be equipped with sensors for adapting the device to the receiving surface. Said device may be secured to a fastening means secured to the receiving surface or completely offset to another surface such as the wall or ceiling of an operating room for example.

By "graphic interface" is meant the interface allowing an easy man / machine dialogue, represented in graphic form, in which are represented in the form of icons or diagrams, all the commands of the instruments that the user can manipulate. By "receiving surface" is meant the surface on which the graphic interface is projected. This surface can in particular separate a first operating space from a second operating space for example to isolate the practitioner.

By "operating space" is generally meant an area of the operating room in which the surgeon and / or his assistants may evolve and / or in which medical devices or objects may be arranged. An operating space can be sterile or not and can be used during an operation or not in particular according to its location in the operating room.

The first operation space and the second operation space can in particular be distinct. The second operation space may for example serve as space for the anesthetist, in the non-limiting case of a surgery operation. Advantageously, the receiving surface is close to the practitioner, at a distance of less than 2 meters, and even more preferably at a distance of less than 1.50 meters. In the case where the control device is equipped with several projection systems, there may be several reception surfaces. The projection surface may be of any kind and advantageously, the receiving surface is a sterile field, used during surgical operations. By sterile field is meant a cloth that, once placed in the medical intervention area, especially during operations (for example in general surgery, visceral surgery, veterinary surgery, but also in interventional radiology in the broad sense, or during endoscopies ...), to define a sterile space in the area of medical intervention. For example, this field is non-woven, and typically it is hooked substantially perpendicular to a patient generally elongates and isolates the space of the surgeon from that of the anesthetist. The sterile field may have sticky edges and may be transparent or semi-transparent. The receiving surface defines two distinct spaces, generally, at least one of the two spaces is sterile. By "object locator" is meant the device capable of detecting the position and / or movement of objects in the space defined by the capture area and the receiving surface. The detected object may be the instrument itself, but also the hand of the surgeon. The technology used for the object-locating system could be a leap-motion technology, using optical sensors, a "Kinect" system, or any other system using the stereoscopic or localization principle. objects.

By "capture zone" is meant the area of the space where the location of the objects takes place. This capture zone, defined as being the active zone in which to place the receiving surface will preferably be located near the practitioner and in particular at a distance of less than 2 meters, and preferably at a distance of less than 1.50 meters. This capture zone will advantageously define the place where to place the receiving surface.

By "communication device" means the device for interconnection of equipment, for example the operating room, but also their order. The device may be wired, wireless, and advantageously said device will communicate by a carrier current link.

"Third person" means any person other than the person performing the medical act, whether surgical or not. For example, the third person may be the anesthesiologist during a surgery operation. In preferred embodiments of the invention, one or more of the following may also be used:

the receiving surface is a flexible surface, and in particular a sterile field; - The receiving surface is disposed in the immediate vicinity of an operating area of an operating room, preferably at a distance of less than 2 meters, even more preferably at a distance of less than 1.5 meters;

the projection device is a video projector and more particularly a cold light video projector;

the receiving surface and the projection device are not in contact;

the capture zone is disposed in the immediate vicinity of an operating zone of an operating theater and has a maximum dimension of less than 2 meters, preferably a maximum dimension of less than 1.5 meters;

the communication device is able to communicate with the medical device by means of an in-line carrier link;

the communication device is able to communicate with the surgical medical device by means of a wireless link; the communication device is able to communicate with at least two medical devices, the device for locating objects is able to detect at least two distinct movements of the at least one object in the capture zone, and the communication device is able to transmit, on respective detection of said at least two movements, at least two respective predefined commands, respectively to said at least two medical devices.

The invention also relates to a remote control method with or without contact, of at least one medical device, in which:

a graphic interface is remotely projected onto at least one reception surface by means of at least one projection device, the receiving surface being a physical surface separating a first operating space from a second operating space,

a movement of at least one object is detected in at least one zone included in the first operation space, by means of at least one object-locating device, and

- On detection of said movement, a predefined command is transmitted to said at least one medical device by means of a communication device. In preferred embodiments of the invention, one or more of the following may also be used:

during an initialization step, detecting a spatial position of at least one point of the reception surface, and defining at least one geometric correction coefficient of the graphic interface and / or the capture according to said spatial position;

during an initialization step, a color of at least one point of the reception surface is detected, and at least one color correction coefficient of the graphic interface is defined according to said color;

- The transmission of a predefined command to the medical device is prevented until an operator has validated a checklist;

- The checklist is projected remotely on the receiving surface by the projection device;

the checklist comprises a plurality of verification points and in which, to validate each of said verification points, at least one movement of said at least one object in the capture zone is detected by means of the object locating device.

The invention will be better understood with the aid of the detailed description which follows, with reference to the appended schematic drawings such as:

FIG. 1 illustrates a device for remote control with or without contact, of at least one medical device according to one embodiment of the invention.

FIG. 2 illustrates a detail of the control device of FIG. 1. FIG. 3 illustrates a graphical interface in one embodiment of the control device of FIG. 1.

The embodiments described hereinafter being in no way limiting, it will be possible to consider variants of the invention comprising only a selection of characteristics described, subsequently isolated from the other characteristics described (even if this selection is isolated within a sentence including these other features), if this selection of features is sufficient to confer a technical advantage or to differentiate the invention from the state of the prior art. This selection comprises at least one characteristic, preferably functional without structural details, or with only a part of the structural details if this part alone is sufficient to confer a technical advantage or to differentiate the invention from the state of the prior art .

Figures 1 and 2 illustrate a remote control device 1 of a surgical surgical unit 2 of the operating theater according to the invention. The device 1 is more particularly designed to remotely control a surgical medical device 2 adapted to perform a modification of the physical state of a patient 3. The modification of the physical state of the patient 3 is in particular carried out by the device 2. The operator 4 may in particular be a surgeon in charge of a surgical operation on the patient 3.

As illustrated in FIG. 1, the control device 1 comprises a projection device 5, an object locating device 6, and a communication device 7. These can in particular be organized functionally as follows. The projection device 5 remotely projects a graphic interface 8 on a reception surface 9.

The object locating device 6 detects a movement of an object 10 in a capture area 11. The object 10 is further detailed below but may, by way of example, be a hand of a surgeon. The movement of the object 10 is for example illustrated by the arrow 20 in the figures.

Finally, on detection of said movement, the communication device 7 transmits a predefined command to Surgical Operating Room Surgical Unit 2.

More precisely, in one embodiment of the invention, the projection device 5 makes it possible to project, through the capture area 1 1 defined by the device, a graphical interface 8 enabling the surgeon to interact on his instruments, c that is to say on the surgical medical device 2, in the non-limiting case of a surgical operation. In one embodiment, the receiving surface 9 is disposed in the immediate vicinity of an operating zone 18 of the operating theater, preferably at a distance of less than 2 meters, even more preferably at a distance of less than 1.5 meters. In this way, the operator 4, in particular the surgeon, can remain standing at the location of the operating field and observe without moving the graphic interface 8.

The projection surface 9 can in particular separate a first operating space 100 from a second operating space 200.

The operating spaces 100, 200 are particularly sterile areas or not in the operating room in which the surgeon and / or his assistants can evolve and / or in which medical devices or objects can be arranged. An operating space may be used during an operation or not in particular according to its location within the operating room. The first operation space 100 may in particular include the capture area 1 1. In one embodiment, the receiving surface 9 is a flexible surface. The receiving surface 9 may in particular be a sterile field. Alternatively, the receiving surface 9 may be a rigid tablet, for example a tablet disposed in the immediate vicinity of an operating area 18, including a sterile tablet. In general, the receiving surface 9 and the projection device 5 are not in contact. This makes it possible to guarantee, if necessary, the sterility of the reception surface 9 in an easy manner.

In a particular embodiment of the invention, the projection device 5 will be a video projector, fixed for example on a bracket, as illustrated in FIG. Part 12 constituting the objective of the video projector may be equipped with an optical system in the broad sense, allowing adaptation of the projection of the interface graph 8 on the receiving surface 9, in particular the sterile field. This embodiment will enable, for example, in the case where the sterile field 9 is fixed on an arm or a mobile gantry 13, to equip the objective 12 with one or more lenses, or any optical system allowing the control of the focusing of the projected graphic interface 8, so as to adjust the focus of the projector 5 or to correct the deformation of the image, whether by optical, electronic or software means. In the same spirit, it will be obvious to understand that the objective 12 of the video projector 5 may include any optical system for making enlargements or narrowing of the display of the graphical interface 8. In another embodiment of the invention invention, the lens 12 may be equipped with color filters in the broad sense, to adapt the color of the graphic interface 8 to the color of the receiving surface 9, including the sterile field, on which the interface graph 8 is projected, with the aim of optimizing the visual contrast and improving the vision comfort of the operator, especially the surgeon.

In yet another embodiment, the graphic interface 8 may be projected by a laser scanning device 5. For example, Micro Vision's PicoP system can be used to project information. Such a projection device 5 may in particular be afocal. In this way, the surgeon will not need to adjust the focus of the projector 5, especially in case of displacement of the receiving surface 9, including the sterile field The operator can thus remain focused on his act.

In another embodiment, the objective 12 of the projection device 5 may be equipped with one or more filters, for example polarized or temporal type with shutters, for projecting 3D information in the capture area 1 1 . The surgeon may in particular wear glasses to visualize this 3D information.

In a preferred embodiment of the invention, the projector 5 does not contain a fan and may include at least one cold light source such as a light-emitting diode (LED) improving the quality of a sterile interventional medium such as a surgical unit.

In a preferred embodiment of the invention, the projection device 5 is located on the opposed to the sterile medical interventional zone or operative field, with respect to the receiving surface 9, in particular the sterile field, and projects a graphical interface 8 at least partially inverted. A user, for example a surgeon, and another user, for example the anesthetist, can have their own graphical interface respectively.

In a particular embodiment of the invention, the projection device 5 will be equipped with one or more sensors 14, allowing, for example, the positioning measurement of the reception surface 9, in particular of the sterile field, or the detection of the shape of the receiving surface 9, especially the sterile field. In this way it is possible to guarantee an optimal visualization of the interface 8 and the projected information by adapting the projection device 5 of the image to the deformation of the projection zone. For example, we can use a computer program that will correct and / or adapt the projection device 5 as the Projection Mapping technique. Thus, for example, during a step of initializing the system and the control method, it is possible to detect the spatial position of one or more points of the reception surface 9, in particular using the sensor 14. This spatial position is for example detected with respect to the projection device 5. Then, it is possible to define at least one geometrical model geometric correction coefficient of the graphical interface 9 as a function of said one or more spatial positions. Thus, it will be possible to calibrate for example the position of the fingers or the location of the projection zone.

Moreover, during said initialization step, it is also possible to detect the color of one or more points of the reception surface 9, in particular by means of the sensor 14. It is then possible to define at least one coefficient of color correction of the graphical interface 9 according to said color.

In a particular embodiment, the sensor 14 may be on the projector side 5 with respect to the receiving surface 9, as the sterile side, in order to measure and control the light intensity on the field. The user can adapt the power of the lamp of the projector according to the ambient lighting.

Advantageously, the system comprises two sensors 14 localized from and other of the receiving surface 9, in particular the sterile field.

The graphic interface 8 of this invention is defined as any system allowing, for example, a human / machine dialogue, in which objects to be manipulated are typically represented in the form of specific pictograms of each medical device, imitating the physical manipulation of these objects with a pointing system. For example, a graphic representation of the graphical interface is given in FIG.

The object locating device 6 makes it possible in particular to detect the position and / or the movement of the object 10 in the space. This detection defines a capture area 1 1, in which the surgeon 4 can perform control gestures. In a particular embodiment of the invention, the receiving surface is a sterile field. Thus, the user, for example the surgeon, can use this reception surface to carry out a command, without any consequence for the rest of the course of the operation, unlike the use of an LCD screen, where a simple contact between the surgeon and the screen requires a temporary stop of the operation to change the gloves de-sterilized practitioner. This device allows to determine the position of the surgeon's hands, and to define the movement. Thus, it may be attributed to a gesture, a specific action of a medical device and / or surgical realizing a modification of the physical state of a patient for example, while respecting the conditions of sterility applying to the surgeon in a medical interventional environment.

The capture area 1 1 is for example disposed in the immediate vicinity of the operative field of the operating room. The capture zone 1 1 has, for example, a maximum dimension of less than 2 meters, preferably a maximum dimension of less than 1.5 meters, in order to allow the operator to travel entirely through the movements of the arms alone, in particular without requiring a moving the operator 4.

Typically, the object locating device 6 comprises at least one sensor 15 and is optionally completed with one or more transmitters 16.

In a particular embodiment of the invention, these sensors 15 are based on optical sensors, for example at the visible wavelength or IR. The sensors 15 are for example an optical or infrared camera. In a particular embodiment of the invention, the object locating device 6 will use the "Leap Motion" technology. This technology, consisting of a triplet of infrared lamps 16 and 2 optical sensors 15 allows lighting of the scene via an IR transmitter. The sensors 15 capture the light intensity reflected by the objects 10.

It is quite obvious and easily understood by those skilled in the art that the invention will not be limited to this type of technology for locating objects. In a particular embodiment, the "Kinect" system may be used, as may the "Wavi Xtion" (ASUS) system or any other system using the stereoscopic or object-localization principle.

The objects 10 include for example the hands, the fingers and / or the forearm of the surgeon or the instruments of medical interventions.

The position of the hands, fingers and / or the forearm of the surgeon can be detected, as well as medical intervention instruments without the need for a sensor to be worn by the surgeon.

The control system 1 may comprise at least one parameterizing means for calibrating the projection of the graphical interface 9 relative to the object locating device 6 and the position of the receiving surface 8, in particular the sterile field. This parameterization means, comprising mechanical elements or comprising processing elements by software or, comprising mechanical elements and software treatments, makes it possible, in particular, by modifying the angle of inclination of the device for locating objects 6. to modify, according to the needs of the user, the capture zone 1 1 by confining this limited volume space with respect to the capacity of the object locating device 6. The setting device of the locating device 6 can also be automated using motor means.

Thus, similarly to what has been described above concerning the projection device 5, during an initialization step, it is possible to detect a spatial position of at least one point of the reception surface 9. For example, the spatial position with respect to the projection device 5 or to the device for locating objects 6. It is then possible to define at least one geometric correction coefficient of the capture area 1 1 according to said spatial position of at least one point of the receiving surface 9.

In a nonlimiting manner, the various possible commands of surgical medical devices are for example; -control of the power intensity of the electrocautery or any medical hemostasis device

-control electrocoagulation modes (bipolar, monopolar ...)

-control of the positioning of the operating table

-control of tumor destruction system (eg power echo, radiofrequency, ...)

-control of different materials located on a laparoscopic column (insufflator, camera, cold light ...)

In particular embodiments, the system may also allow the control of devices and other elements of the operating theater, in particular: - control of intraoperative imaging system (for example ultrasound ...)

- triggering the capture and reading of videos, patient files (radiology, antecedents ...)

-control of the positioning or the intensity of the operating light These commands are integrated within a graphic interface 8 adapted in terms of ergonomics to the projection and interaction device (size of the buttons, colors, sequences, etc. .). Indeed, since the sterile fields are generally blue or green, the choice of interface colors should make it possible to optimize the color rendering of the latter on the sterile field, for example by using colors that are opposite to blue and green. green on the color wheel. The sterile field is then a suitable background for the projection of the graphical interface 8 as detailed above.

The capture area 1 1 created by the projection device 5 can define the place where the GUI 8 is projected. Typically, this capture zone 11 will be delimited at at least one end by the passive receiving surface 9, in particular a sterile field.

By sterile field is meant a cloth that, once placed in the medical intervention area, especially during operations (for example in general surgery, visceral surgery, veterinary surgery, but also in interventional radiology in the broad sense, or during endoscopies ...), to define a sterile space in the area of medical intervention. For example, this field is non-woven, and typically it is hung substantially perpendicular to an elongated patient and generally isolates the space of the surgeon from that of the anesthetist. The sterile field may have sticky edges and may be transparent or semi-transparent. Generally, it is attached to at least a bracket with a hooked system. In a particular embodiment of the invention, the sterile field may be fixed on a horizontal or vertical bar, itself fixed on the operating table or directly on the ground.

In a particular embodiment of the invention, this field may be held on a movable arm, allowing it to be easily moved. In addition, the entire projection system / capture area can be secured to an arm fixed for example on the wall or on the ceiling. Thus, this set could be located on both sides of the operating sterile field.

Of course, it will be easy to understand that the receiving surface 9 on which the graphic interface 8 is projected will not necessarily be sterile. The invention may be used for example, in a particular embodiment, for endoscopic examinations, or the sterility of the operating room or examination is not an obligation.

A data processing system 17 makes it possible to determine the positions of an object 10 and to define its movement. It can be embedded in at least one of the devices of the system 1 or deported thereof. It can also be embedded in an implanted computing unit and can notably be integrated in the device for locating objects 6 or projection 5. It can typically be a processor, a computer or a tablet . A data processing system is any system that allows the model to be modeled by any means whatsoever. position and / or movement of an object in space relative to the projected graphical interface and to define a pointing system.

The communication device 7 and transfer commands allows interconnection with the equipment of the operating room and their order. Such a device can send a signal to the electronically controlled medical devices of the medical interventional medium for example to control the position of the operating table. The term "communication device 7" and "transfer of commands" means any device that makes it possible, for example, to interact and control, in particular, the functionalities of the surgical medical devices of the medical interventional environment, of the databases, of the connected network.

The control system 1 according to the invention thus makes it possible in particular to use, in a medical interventional environment, a virtual interface projected on a sterile field which generally separates the space of the (sterile) surgeon from that of the anesthetists and avoids in particular the doctor to have to take the risk of contaminating and therefore having to change his desilterized gloves for the control of medical equipment. The sterile field typically positioned at the beginning of intervention and generally maintained by a fastening system such as a set of brackets. Moreover, the device can be equipped with a voice control system. In this particular embodiment of the invention, the voice control system may allow the surgeon to switch on and / or switch off and / or put the device in standby. In addition to this particular mode, the device may include a sound reproduction system. The surgeon will be certain, without the need to check visually, that the command he has just passed has been taken into account by the device. He will be able to use his equipment safely.

In addition, the various systems of the device can communicate with each other and / or with the equipment of the medical interventional environment by a cabling system or by a wireless system, for example using Wifi or Bluetooth technology. In a preferred embodiment of the invention, the various systems of the device can communicate with each other and / or with the equipment of the medical interventional medium by a cabling system CPL (carrier current). Thus, in particular, the communication device 7 may be able to communicate with the operating theater surgical medical devices 2 by means of an in-line carrier link.

This technique, highlighted by the construction of an inexpensive, reliable and resource-efficient computer network, is ideal for the integrated and largely automated management of all instruments.

As a variant, the various systems of the device will be able to communicate with each other and / or with the equipment of the medical interventional environment via wireless links. Thus the communication device 7 may be able to communicate with surgical medical equipment 2 operating room by means of a wireless link.

Finally, the device can receive a power supply by any means, in particular by sector or battery. In a particular embodiment where it has the presence of a wiring system, the interconnection cables would preferentially integrate with the sterile field fixing system, in order to minimize the passage of the cables in the middle of the operating chamber.

The system 1 according to the invention may in particular be implemented in a method for remote control of a surgical medical device 2 operating theater as will now be described. Such a method may in particular be especially intended for remotely controlling a surgical medical device 2 adapted to perform a modification of the physical state of a patient 3 according to a predefined command from an operator 4

In such a method according to the invention, implemented by means of a control device 1 according to the invention:

a graphic interface 8 is remotely projected onto a reception surface 9 by means of a projection device 5,

a motion of at least one object 10 is detected in a capture zone 11 by means of an object locating device 6, and

- Upon detection of said movement, a predefined command is transmitted to the operating theater surgical medical device 2 by means of a communication device 7. In a particular embodiment, the transmission of a predefined command to the operating theater surgical medical device 2 by means of the communication device 7 can be prevented until an operator 4 has validated a checklist. The control system can only be active with the various medical devices after validation of a data checklist to secure the operating procedure

The checklist may for example be displayed on the reception surface 9, in particular by being displayed on the graphic interface 8 remotely projected by the projection device 4. The checklist is for example a list comprising several checkpoints. . By "verification points" we mean elements that the operator 4, in particular the surgeon or assistant, must check to meet legal obligations or not (checklist kind of drivers) before conducting the operation.
