Configuration of Intelligent Surgery System
FIG. 3 shows in detail the internal configuration of the intelligent surgery system 200 according to one embodiment of the invention.
As shown in FIG. 3, the intelligent surgery system 200 according to one embodiment of the invention may be configured to comprise a data matching unit 210, a surgery control unit 220, a data management unit 230, a database 240, a communication unit 250 and a control unit 260. According to one embodiment of the invention, at least some of the data matching unit 210, the surgery control unit 220, the data management unit 230, the database 240, the communication unit 250 and the control unit 260 may be program modules to communicate with the robot 100 or the user control device 300. The program modules may be included in the intelligent surgery system 200 in the form of operating systems, application program modules or other program modules, while they may be physically stored in a variety of commonly known storage devices. Further, the program modules may also be stored in a remote storage device that may communicate with the intelligent surgery system 200. Meanwhile, such program modules may include, but not limited to, routines, subroutines, programs, objects, components, data structures and the like for performing specific tasks or executing specific abstract data types as will be described below in accordance with the present invention.
Meanwhile, the intelligent surgery system 200 may be configured to be physically separated from or combined with the robot 100 or the user control device 300, as desired by those skilled in the art.
First, the data matching unit 210 according to one embodiment of the invention may receive the aforementioned data from the information collection device of the robot 100, and, in some cases, receive the aforementioned information on the patient from the user control device 300. Further, the data matching unit 210 may find control data matching the received data or information with reference to a data matching matrix that may be stored in the database 240, and provide the control data to the surgery control unit 220.
As for the data matching matrix according to one embodiment of the invention, dimensions of the matrix may correspond to the types of the data from the information collection device and/or the types of the information on the patient from the user control device 300, categories of the dimensions of the matrix may correspond to the values or ranges of values of the data from the information collection device and/or the values or ranges of values of the information on the patient from the user control device 300, and elements of the matrix may correspond to the values of the control data on the surgical actions to be performed according to the corresponding data from the information collection device or the corresponding information from the user control device 300.
Examples of the data matching by the above data matching matrix are as follow:
1. The control data may be used to control the suture interval to be smaller as the age of the patient (except infants) is younger and the elasticity of the surgical site is higher or the distribution of the blood flow in the surgical site is denser.
2. When the internal temperature or the acidity of the surgical site is low, the control data may be used to increase the thickness of the suture thread or suture needle (e.g., for suturing of a stomach).
3. When a large amount of blood is detected at the surgical site, the control data may be used to change the suture thread to an insoluble suture thread capable of tolerating high pressure for a long period of time.
4. When the distribution of the blood flow in the surgical site becomes denser, the control data may be used to decrease the thickness of the suture thread or suture needle.
5. The control data may be used to decrease the suture interval or increase the tension of pulling the suture thread, when the surgical site is presumed to be arteries as red blood cells, white blood cells, a pressure of 120 mg and an oxygen saturation of more than 80% are detected or recognized therein.
6. On the contrary, the control data may be used to increase the suture interval or decrease the tension of pulling the suture thread when the surgical site is presumed to be veins.
7. The control data may be used to change the suture thread to a soluble thread for calculus prevention, when the surgical site has a tubular structure (the morphological information may be inputted by the user in advance) and urine component is detected at the surgical site.
8. The control data may be used to change the suture tread to an antibiotics-treated thread when the tissue necrosis is detected at the surgical site.
9. The control data may be used to change the suture thread to a suture thread easily identifiable by X-rays when cancer cells are detected at the surgical site.
10. The control data may be used to pause the suturing action of the suturing device or change the suturing mode when a large amount of blood, intestinal secretion, tissue necrosis or cancer cells are detected at the surgical site.
11. The control data may be used to stop the surgical instrument or suturing device when the elasticity of the surgical site is identified to be almost zero.
12. The control data may be used to change the surgical instrument to an electrocautery when a large amount of blood is detected at the surgical site.
13. The control data may be used to switch the mode of the electrocautery to a hemorrhage prevention mode when a large amount of blood is detected at the surgical site.
14. The control data may be used to change the surgical instrument to an electric knife, an electrocautery, a laser emitter or a drug spray when tissue necrosis or cancer cells are detected at the surgical site.
15. When the surgical instrument perform an action to hold the surgical site, the control data may be used to control the pressure of the action according to the elasticity of the surgical site.
Although only some of the examples of the possible data matching have been listed above, it will be apparent to those skilled in the art that more diverse examples of the data matching other than the above ones may be envisaged as accumulating and utilizing in combination the data from the information collection device or the information on the patient from the user control device 300.
Next, the surgery control unit 220 according to one embodiment of the invention may transmit to the robot 100 a control signal to allow the surgical instrument or suturing device to operate in accordance with the control data matched by the data matching unit 210. Further, the surgery control unit 220 may display to the user in advance the contents of the above operation control via the display means of the user control device 300.
The surgery control unit 220 may carry out automated control only depending on the matched control data, but may also carry out surgery control only after requesting and receiving the user's approval of the surgery control according to the matched control data. In the latter case, on the basis of the decision based on the user's surgical experience, the user may grant the above approval or else reject the approval and select the surgery control having the changed contents to be carried out.
Further, as the user issues a command by means of the user command device 300, the surgery control unit 220 may transmit to the robot 100 a control signal to control the operation of the base, robotic arms, endoscope, surgical instrument, information collection device, suturing device or the like.
Next, when the user makes a manipulation to change the contents of the surgery control using the user control device 300, the data management unit 230 according to one embodiment of the invention may significantly or slightly change the values or range of values of the corresponding matched control data (e.g., the control data on the suture interval, type of the suture thread, type of the suture needle, tension of pulling the suture thread, or the like) in accordance with the above contents, thereby updating the data matching matrix. In this case, the data management unit 230 may issue a message to the user to ask whether he/she wants the update, and request a confirmation from the user.
Next, the database 240 according to one embodiment of the invention may store the data matching matrix as described above. Although FIG. 3 shows that the database 240 is configured to belong to the intelligent surgery system 200, the database 240 may be configured separately from the intelligent surgery system 200, as needed by those skilled in the art to implement the invention. For example, the database 240 (and the data matching matrix thereof) may be built on a web server so that they may be consulted or updated by a large number of distributed users.
Next, the communication unit 250 according to one embodiment of the invention may perform a function to enable data transmission/receipt to/from the data matching unit 210, the surgery control unit 220, the data management unit 230 and the database 240.
Lastly, the control unit 260 according to one embodiment of the invention may perform a function to control data flow among the data matching unit 210, the surgery control unit 220, the data management unit 230, the database 240 and the communication unit 250. That is, the control unit 260 according to the present invention may control data flow into/out of the intelligent surgery system 200 or data flow among the respective components of the intelligent surgery system 200, such that the data matching unit 210, the surgery control unit 220, the data management unit 230, the database 240 and the communication unit 250 may carry out their particular functions, respectively.
The embodiments according to the present invention as described above may be implemented in the form of program instructions that can be executed by various computer components, and may be stored on a computer-readable recording medium. The computer-readable recording medium may include program instructions, data files, data structures and the like, separately or in combination. The program instructions stored on the computer-readable recording medium may be specially designed and configured for the present invention, or may also be known and available to those skilled in the computer software field. Examples of the computer-readable recording medium include the following: magnetic media such as hard disks, floppy disks and magnetic tapes; optical media such as compact disk-read only memory (CD-ROM) and digital versatile disks (DVDs); magneto-optical media such as floptical disks; and hardware devices such as read-only memory (ROM), random access memory (RAM) and flash memory, which are specially configured to store and execute program instructions. Examples of the program instructions include not only machine language codes created by a compiler or the like, but also high-level language codes that can be executed by a computer using an interpreter or the like. The above hardware devices may be changed to one or more software modules to perform the operations of the present invention, and vice versa.
Although the present invention has been described in terms of specific items such as detailed elements as well as the limited embodiments and the drawings, they are only provided to help general understanding of the invention, and the present invention is not limited to the above embodiments. It will be appreciated by a person of ordinary skill in the art that various modifications and changes may be made from the above description.
