Description

JOYSTICK CONTROLLED HAND UNIT AND WIRELESS DATA TRANSMISSION TECHNOLOGY AND METHOD FOR ENDOSCOPY DEVICES

Technical field:

Background Art:

Endoscopy devices, which are especially used in medical sector, are composed of two main sections. Tip of the endoscopy device is located according to the place, which is intended to be displayed, by means of hand and wrist actions over hand unit during inspection and operations, and obtained image is transmistted to the recording and image transmitting section of the display terminal by means of a system with wire. During the procedure, the surgeon must try to position the endoscope at the same time as he or she wants to see the endoscope by using his or her fingers, hand and wrist during the procedure, and by working with his body according to the location of the imaging device, turning it in that direction.

In addition, the device acts as a tool to help visualize only if the structure is not suitable for providing additional features. The size of the imaging unit is not suitable for placement in different shapes so as to provide positioning and ease of use in a working environment with the bulkiness.

The technical problems aimed to be solved by the invention:

Endoscopy devices become increasingly important and become a necessity with the release of open surgical and examination methods day by day. Generally speaking, products are being used in a short period of time due to the structural difficulties and the costs of the technology in the period they are produced, resulting in a relatively high cost of switching over to a new technology. Due to these costs, this device which is necessary for every doctor cannot be found in all the examinations. With this technology developed, the endoscopy unit will be small enough to be carried in a simple handcraft and the cost will be reduced despite the increase in usage characteristics thanks to the developed technologies. With the disabling of the bulky structure of the imaging unit, it will provide great advantages in terms of area usage in offices, examination rooms, and operating theaters.

Today, thanks to the developing technology and skills, open surgeons (5%) left their place in endoscopic surgeries (95%). Transfusions to open surgical endoscopic procedures have resulted in some great disadvantages as well as significant benefits for patients and surgeon. With the transition to endoscopic surgery, the duration of the operation is prolonged. During these prolonged operations, the surgeon is obliged to stay in the normal posture (posture) for a long period of time in the form of an improper posture, and the back and headache occur due to the same direction and side view for a long time. In addition, increased repetitive wrist movements during endoscopic instruments cause upper extremity pain and fatigue. When we look from the patient point of view, the prolongation of the operation is shown in recent studies where upper extremity fatigue increases the complication rate (back injury during operation) of the back pain headaches, and single session operations are left to other sessions. From a surgeon's point of view, long - term inappropriate posture leads to diseases such as neck and waist pain, waist and neck hernias, carpal tunnel syndrome, ternary neuropathy, arthritis that do not develop in the future. Surgeons who are caught in such negativity are forced to make a substantial amount of money for the treatment of these diseases, as they are forced to leave their long-term leave. The motion capabilities of known endoscopic devices are limited by finger, hand and wrist movements. With this new technology, motion is provided by a finger-controlled joystick. In this way, it will prevent the occurrence of uncomfortable pain on the hands and wrists during long hours and hours of work, the long period of uncomfortable pain in uncomfortable positions, and the necessity of carrying the hand module of the endoscope device with one hand by taking advantage of the structural characteristic of the hand unit. In the currently used devices, the image from the hand module is transferred via the wired system to the imaging and recording unit. In this way, the modular cabling that is used once in the work area occupies space, and even limits your mobility considerably. The developed technology will enable wireless data and image transmission between the handheld unit and the peripheral imaging units in the environment, thus disabling the cable clutter. In addition, the use of cables for additional imaging units or recording devices on this site will also be disabled.

Due to the size of the imaging units of current endoscopes, there is a problem of placement in the surgery or examination and it is necessary to look at the body or head turning during the procedure. The use of endoscopes causes occupational diseases during the working period which lasts at least once a week and continues for years. Although the imaging unit is placed in the most appropriate way, especially in the operating theater, every time it is needed, the staff member and the doctor will have to look at the same condition, turning the head or body. With the technology to be developed, it is possible to carry out the operation without the necessity of fixing the head and body or the head, which is wirelessly transmitted from the hand unit of the endoscopic device through specially produced virtual reality glasses per person who performs surgery or examinations, You will be able to. The virtual reality glasses used in the market are not suitable for use in operations such as surgery and examination. Particularly, glasses that are fixed by attaching to the head cause serious problems when it is needed to be removed during the operation, and they need help because of sterile conditions. As an alternative to these glasses, the part attached to the head will have the ability to move, so it will be possible to work with the eye by lifting the eye with a simple hand movement during the study. With the camera integrated in the virtual reality camera of the developed product, it is possible to acquire the image when the visual data should be taken from the external environment for a long time during the operation.

This image can be displayed entirely and through the hand unit, this camera can be turned on and off, and many images from x-ray films to visual images, which will be needed with the USB connection integrated into the virtual reality goggle, can be instantly ported to the eye with a simple keystroke, this data can be reached without breaking before work.

With the features of the device developed during the operation, instant voice and video recording can be done with a single unit in order to be able to use it in the event that it can be used both in the educational and the end result.

The system has been developed to create a more comfortable and effective working environment for the endoscopy devices which are widely used in the biomedical field, with the help of wireless data transfer technology, problems caused by the use of endoscopy device by means of image and data transfer and limited opportunities. The technologies and techniques used in this context have been specially selected by taking into consideration the negative situations that may occur within the scope of health standards and are developed according to the convenience of use in this application. It is planned to work in concert with the endoscopy devices currently in use to improve its use and properties without completely disabling the entire device in the first stage.

Structure and characteristics:

The two-unit system is configured to move the endoscope 1 towards the endoscope 1 with the movements of the motor (26) that drives the endoscope device 360° controlled by the position adjuster joystick (6) on the hand unit (8) and the motors (28) that control the endoscope device control bar is precisely positioned. The position data (electromagnetic signals) transmitted from the position adjuster wireless joystick (6) are transmitted to the motors (26, 28) having a step range of 0.18° through the motor control circuit (29) of the endoscopic device in a controlled manner. Thus, the joystick (6), which may come into play, prevents the motors (26, 28) from operating erratically in the event of electrical malfunction.

The correct positioning of the endoscopic device and during operation the image taken from the viewfinder (23) is digitized by means of the camera (24) having a high imaging capacity so that it serves as the wireless transmitter (32) which will allow the image to be transmitted without losses to the wireless receiver (37), the electronic card (32) transmitting the special functions to the receiver is transferred. A camera sharpness adjusting slide button (5) is used to adjust the sharpness of the camera (24) in the position of the viewfinder (23) or in the direction of the user's special request.

Images taken with the camera (24) at the endoscope (1) are wirelessly transmitted to the receiver via the wireless transmitter system (8). One of these receivers is transferred to the receiver (16) in the waist unit and the imaging screen (11) in the head unit from there. Via the keypad (7), various features, such as the control sensitivity of the motors (26,

28), emergency stop, recording start, stop, display of data stored in the USB memory attached to the external memory port (36) in the image display area (43) on the screen, shall be maintained on the handpiece (8). Thanks to the illumination of the keypad (7), feedback on the handpiece (8), ie pre-snapshot recordings can also be followed.

Under the hand unit (8) there is a Li-Po battery (31) which is able to meet this unit's power requirement for a minimum of 5-6 hours, but which does not cause excessive weight during use. The battery (31) can be charged from the charging port (22) located on the hand unit. Moreover, this battery (31 ) is capable of being easily disassembled even during use.

The magnet (30) is positioned so as to allow the hand unit (8) to stand upright and remain stationary at the bottom. In this case, the hand unit (8) may be fixed to the steel metal surface when the work is interrupted or when there are conditions such as hand fatigue during operation. In addition, the hand rest piece (17) is provided on the hand unit (8) to minimize hand and wrist fatigue during long work. The part worn on the user (10) of the system consists of a head unit shown in Fig. 4 and two parts fitted to the waist shown in Fig. 5. There are wireless receiver (37) to which the wireless data transmitted from the hand unit (8) is transmitted in the wireless receiver unit (16) is connected to the wireless receiver antenna (19) by processing the data received from the wireless receiver (37) and processing the images sent from the hand unit (8), a mini computer (38) enabling the display of the image data and the execution of the recording operations, a hard disk (39) where the data can be recorded, an external memory connection port (36), a connection port (20) for recording and transmitting images to external display units, and a battery (40) which is strong enough to provide an average working time of 5-6 hours.

The head unit shown in Fig. 4 is composed of the display screen (11), camera (12), the slide holder (18), the head carrier bands (13), the button (14) for fixing and tightening the head carrier and the connection cable (15) for transmitting data between the head unit and the waist unit.

The display (11) on the head unit can be turned off by pushing it up from the tip if desired and it can be passed on to the eye. Also thanks to the camera (12) in this section, real-time snapshot recording is possible during use. Thanks to the features of the display area (43) on the screen (11), it is suitable for both development and use. These features can also be managed by the mini computer (38) located in the waist unit (16).

It is designed to be extremely suitable to be developed due to the features of the system structure and the electromechanical components used.

Preparation for usage and resetting:

The system consists of a hand unit (8) used by the user (10), a display module head module (Figure - 4) and an image provider unit (16) as shown in Figure - 1.

Before use, the appropriate endoscopic device carrier (3) designed for the existing endoscopic device (1) must be selected. This carrier slider (3) has specially designed models for several different types of endoscopy devices (1) located on the market. Due to the specific construction of the different model endoscopy devices (1 ) the handle (2) is specially designed to allow the use of existing devices in the carrier slide (3) such as the position of the working channels (41). The endoscopic device (1) allows the endoscopic device (1) to be inserted into the handpiece unit (8) from the handle (2) to the working channel (41) and into the carrier unit (3). The cradle (3) with the cradle (4), which is provided with a return motion to the endoscopic device (1), is fixed to the middle casing (25) by means of the drum (4) by screwing. If the wrong carriage guide (3) is used for the wrong endoscopy device (1), the drum (4), which provides 360° rotation due to its structure, will not settle and cannot be fixed. Thus, the use of the faulty slide (3) will be avoided. In this way the use of the endoscopy device (1 ) with the hand unit (8) will be ready.

The ready-to-use hand unit (8) must be fully occupied in accordance with the service life of the hand-held battery (31) and the exact position of the endoscope (1) must be known so that it can fully fulfill its function during operation. If the handpiece battery (31 ) is too low to be used, the keypad (7) lights will flash red 5 times and turn off. If the handset battery (31 ) is full of operation for more than 1 hour according to the average operation intensity, normal operation procedure will be started and hand unit battery status (45) will be shown on the user's (10) head unit display (42) when fully engaged. The hand unit is moved to the zero position by means of the 360° rotation motor (26) and the endoscopic device control rod control motor (28) so that the hand unit (8) can adjust its position after being activated by the keypad (7), it is set. During this resetting process, the user (10) is informed by the colored LED lights located under the keypad (7). Also during this process, the user (10) is informed via the display screen (11 ) as well. In the reset operation, the hand unit is first actuated by the motor control circuit 29, and the hand unit 360 ° motor 26 is actuated. This motor (26) is capable of rotating the turn gear tooth (27) exactly 360 ° depending on the structure in each case. For this reason, the conveyor roller (3) will return to its original position by turning it exactly 360 ° from its initial position. This will occur when the handpiece (8) is in use and the endoscope (1) can be rotated 360 ⁰ to the right and left.

The second part of the resetting operation is again the actuation of the endoscope control rod control motor (28), which is governed by the hand unit motor control circuit (29). This motor (28) moves the control rod motor connection apparatus (35). This movement allows the endoscope (1 ) to move up and down. Also, the control rod (28), which is 180° rotatable to determine the first use position of the endoscope (1 ), moves forward and backward by a full stroke, bringing the control bar to the zero point of the motor connection apparatus (35).

At the end of the reset operation, the illumination lights under the keypad (7) will start to flash according to the result of the reset operation if there is a problem with the red LEDs according to the predefined problem. The illumination lights under the keypad (7) start flashing in yellow when there is no problem with the resetting of the first controls and the handset unit (8) informs that the wireless connection protocol of the image provider unit (16) is being operated. When all the operations are completed and there is no problem, the keypad (7) illuminates in green color and the device is ready for use.

Operation and usage:

The endoscopic device ready for operation is started to be used by the user (10) in the conventional manner at the site of application. The handheld unit (8) will also be wirelessly transmitted to the image provider (16) located at the waist of the user (10). At this time, the illumination under the keypad (7) of the handpiece (8) will be lit in steady green so that the keys (7) will be easier to see if used in the dark and the user (10) will be informed about the operation of the device. Also, the wireless connection status (46) is displayed on the user screen (11) and the image received from the endoscope (1 ) on the display screen (43) can be displayed. When the endoscope (1 ) is advanced into its use area, the user (10) directs the endoscope (1 ) via the joystick (6), which is managed with the help of the thumb. This is accomplished by moving the joystick (6) forward, backward, right, left and intermediate directions. After resetting, the endoscope position (44) in the upper left corner of the screen display area (43) will indicate the zero position. As the endoscope (1) is moved with the help of the joystick (6), the position of the endoscope (44) will be displaced and the exact position of the endoscope (1) will be indicated.

When the endoscope (1) is operated by the control joystick (6) during operation in the work area, it is necessary to record the image, camera image or both taken from the endoscope (1) with the keypad (7) may start. At the start of recording, this will activate markers (50, 51 ) on the user screen (1 1) indicating the state of the individual recording for both the endoscope (1 ) and the head unit camera (12). In the screen display area (43), the date and time (53) of the day on which the work was performed will be displayed during the recording (52). Thus, when recording the diskette (39) on the recorder, the file name will be created based on the date and time (53) on the screen. Recording will be indicated by the cursor (54) indicating the disk space occupancy on the screen (43) while the diskette (39) in the image provider (16) is being recorded. During the use of the device and during recording, if the light of the endoscope (1) is insufficient, the illumination for the endoscope device can also be activated via the keypad (7). This is also informed to the user with the cursor (49), which indicates the light status on the user screen (1 1). The images stored in the USB memory attached to the external memory connection port (36) of the image provider unit (16) can also be displayed on the screen (11 ) by the user using the keypad (7) in the image display area (45) by the user (10). Through the application operated on the mini PC (38) in the image provider and with the help of the keypad (7) it will be possible to switch between the images. Depending on the application areas, the application run on this mini PC (38) may also allow for many possibilities such as increased realism.

Wireless data communication between the hand unit (8) and the image provider unit (16) will be encrypted according to certain protocols. For this reason, conflicts with other devices used in the same environment or in close proximity, such as the occurrence of data transmission problems or the appearance of a different device, will be avoided. When the image taken from the hand unit (8) is to be displayed on a different screen at another point, the image can be transferred wirelessly with an extra receiver manufactured for itself or via a cable connected to the connection point (20) on the image provider unit (16). In this way, more than one point endoscope (1) image and head unit camera image (12) can be simultaneously displayed and recorded. Industrial application :

Since the parts making up the system can be easily procured from the market, there will be no problems in the production phase. It will be primarily used in the medical sector, especially in structures that will be sterile and capable to be used in laparoscopic operations. This shall mainly be used in this area because it contains all the features detected missing in the medical sector as well as monitoring and imaging.
