Description

ROBOTIZED APPARATUS FOR SURGICAL OPERATIONS
The present invention relates to a robotized apparatus for surgical operations.
As is known, nowadays many surgical procedures, especially in some areas like urology, are carried out by way of a robot controlled remotely by a surgeon.
To this end, the surgeon has a computerized command console located inside the operating theater.
The console is generally provided with a three-dimensional viewer, which receives images from one or more stereoscopic video cameras fixed to the robot and arranged so as to frame the operating field, as well as commands that reproduce the grip of the surgical instruments used by the robot (forceps, surgical scissors, dissectors etc.).
Although the use of stereoscopic video cameras and three- dimensional viewers improves the visual perspective of the surgeon and enhances in him/her the sensation of operating directly on the patient, in order to increase the precision of some very complex surgical maneuvers it would be useful for the surgeon to have an additional visual aid.
In the past, systems have been proposed for integrating the image of the video camera with computer-generated three-dimensional reproductions of the organ being operated on, but they have been found not fully satisfactory in terms of practicality of use and, as a consequence, to date they have found little application.
Therefore, the main aim of the present invention is to improve the known robotized apparatuses for surgical operations, so as to guide the surgeon in a practical and reliable manner in identifying the outlines of the anatomical parts viewed and, as a consequence, in reaching the points to be operated on with the surgical instruments.
The above aim and other objects, which will become clearer from the description that follows, are achieved by a robotized apparatus for surgical operations having the characteristics recited in the appended claim 1, while the appended dependent claims define other characteristics of the invention which are advantageous, although secondary.
Now the invention will be described in greater detail, with reference to a preferred but not exclusive embodiment thereof, which is illustrated for the purposes of non-limiting example in the accompanying drawings, wherein:
Figure 1 is a schematic view of the robotized apparatus according to the invention;
Figure 2 shows the scene viewed by the surgeon with the apparatus in a first operating configuration;
Figure 3 is an image relating to the operation of the apparatus according to the invention;
Figure 4 shows the scene viewed by the surgeon with the apparatus in a second operating configuration.
With reference initially to Figure 1, a robotized apparatus for surgical operations 10 is adapted to be installed in a generic operating theater.
The apparatus comprises a robot 11 provided with mechanical arms 12a, 12b which are fitted with surgical instruments 14a, 14b that are adapted to operate on a generic patient P arranged on an operating table B.
A surgeon S controls the robot 11 remotely by way of a computerized console 16.
To this end, the robot 11 comes with a stereoscopic video camera 18 installed, which is supported so as to frame the operating field and is connected in order to transmit its video signal VID to a three-dimensional viewer 20 with which the computerized console 16 is provided.
The computerized console 16 is furthermore provided with commands 22 that can be actuated by the surgeon S, which are configured to reproduce the grip of the surgical instruments used by the robot (forceps, surgical scissors, dissectors etc.). In a way that is known per se, the computerized console 16 is furthermore provided with auxiliary video inputs 24 and with assignable inputs 25 for accessory control devices.
Figure 2 shows the video signal VID of the operating field captured by the stereoscopic video camera 18.
According to the invention, in order to guide the surgeon S in identifying the outlines of the anatomical parts viewed and, as a consequence, in reaching the points to be operated on with the surgical instruments, the robotized apparatus according to the invention further comprises:
- a processing unit 26, which is connected in order to receive the video signal VID from the stereoscopic video camera 18, and is programmed to superimpose on such video signal VID a three-dimensional virtual image 3D IMAGE of the organ to be operated on (Figure 3), and to transmit the resulting combined image VIDEO COMB (Figure 4) to the three-dimensional viewer 20 through the auxiliary video inputs 24 on the computerized console 16,
- means for manipulating 28 which can be activated in order to move and orientate the three-dimensional virtual image 3D IMAGE in relation to the movements of the real organ in the three-dimensional viewer 20,
- means for switching 30 which can be actuated to selectively display the video signal VID or the combined image VID COMB on the three- dimensional viewer 20.
As is known, the movements of the real organ in the three- dimensional viewer 20 can be due, e.g., to movements of the video camera caused by the surgeon S.
In the embodiment described herein, the means for manipulating 28 advantageously comprise a device for manual control, in particular a three- dimensional mouse, which is controlled by an assistant operator A who assists the surgeon by accompanying the movements of the video camera. To this end, the combined image VID COMB is preferably displayed on an auxiliary screen 32 which is accessible to the assistant operator A.
In this embodiment, the means for switching 30 advantageously comprise a pedal switch that can be connected to the assignable inputs 25 and which can be actuated directly by the surgeon S.
The three-dimensional virtual image 3D IMAGE of the organ can be reconstructed, in a way that is known per se, starting from two-dimensional images generated typically by way of computerized tomography or magnetic resonance.
The programming of the software to superimpose the images is part of the normal knowledge of the person skilled in the art and lies outside the aims and objectives of the present invention; therefore, it will not be described here.
Generally, the three-dimensional virtual image 3D IMAGE can be stored in a memory unit 34, which can be external or integrated in the processing unit 26.
In the operation, at the moment of the operation, the three- dimensional virtual image 3D IMAGE is loaded in the software and sent to the console 18 combined with the real image captured by the stereoscopic video camera 18, as illustrated in Figure 4.
The surgeon S views the operating field by way of the three- dimensional viewer 20 and, by acting on the pedal switch 30, switches at will between the traditional display mode, in which the pure video signal VID captured by the stereoscopic video camera 18 is shown in the viewer (Figure 2), and an "assisted" display mode, in which the combined image VID COMB (Figure 4) is shown in the viewer.
The assistant operator A monitors the combined image VID COMB on the auxiliary screen 32, and assists the surgeon S during the operation by rotating and moving the three-dimensional virtual image 3D IMAGE by way of the three-dimensional mouse 12, so that it is always superimposed on the real image of the organ to be operated on.
A preferred embodiment of the invention has been described, but obviously the person skilled in the art may make various modifications and variations within the scope of protection of the claims.
For example, in the embodiment described herein the processing unit 26 is shown separate from the console 16. However, it is evident that the processing unit 26 could be integrated in the console 16.
Furthermore, the three-dimensional mouse for manipulating the three- dimensional virtual image 3D IMAGE could be substituted by other manual means for manipulating, such as joysticks, touch screens and the like, or by automated systems based on image recognition software that can autonomously follow the movements of the real image. In the latter case, in particular, the auxiliary screen 32 would no longer be essential except for monitoring purposes.
In the same way, the pedal for switching between the traditional display mode and the assisted display mode can be substituted by other types of switches which can be integrated in the console or connected as external accessories.
The number of instruments and of video cameras mounted on the robot can obviously vary on the basis of requirements.
Furthermore, although the use of stereoscopic video cameras and of three-dimensional viewers is preferable, obviously the invention can likewise be applied to systems equipped with conventional video cameras and two-dimensional viewers.
