A FLEXIBLE LENS SYSTEM INTEGRATED TO THE SMART TOUCH SCREEN

FOR MICROSURGERY PURPOSES

Technical Field

The invention is to develop a new surgery and recording device for the microsurgery by means of transmitting the received image from the detection and zoom unit which has an appropriate lens assembly that takes very much smaller volume, into a smart display, by protecting the zooming and focusing features of indispensable large microscopes used in surgical branches where microsurgery is also required. Today surgical microscopes occupy a big space within the operating room. They are bulky due to their being heavy and big. It is very troublesome to sterilize these and bring them to the place where the operation will be made and where they will take their operational position. When the big microscopes are brought onto the operation field, only microscopic view on the binocular lens is used, macroscopic view and general control on the operational field are totally lost. By virtue of the invention, a system which occupies too little place within the operating room compared to the big microscopes, is light and ergonomic, easy to sterilize, easy to position on the operational field, is developed with protected microscopic, macroscopic and general control abilities.

State of the Art

There is no model of this technique in the medical field. It is considered as an alternative to the surgical microscopes. For this reason, the present state and disadvantages of the surgical microscopes will be disclosed. The surgical microscope is first used by Carl-Olof Nylen in 1922. After 1960’s, together with the changes in the microsurgical surgery techniques, it becomes widespread. Today an advanced model of the surgical microscopes is ZEISS OPMI PENTERO 900 model, it has 187 cm length and is 358 kg by weight and its body occupies 87,5x73,6 cm2 area. Due to these physical characteristics, it occupies a big place within the operating room. In order to use it within the surgical field, a big sterile sheath is required. After the sterile sheath is covered, it shall be positioned closer to the surgical field in a most appropriate manner without giving damage to the patient together with the space occupying surgical equipment such as anesthesia, cautery, aspirator, navigation and neuromonitorization devices. This process is troublesome; it requires experienced personnel and time. When the microscope is brought into the operation field, the sensitive region for the operation is determined by means of zoom and focus characteristics, after this determination, the surgeon must take a stable position. This stable position causes muscle and backbone pains during long surgical operations, and due to pain and tiredness, it leads to loss off fine hand motions and lack of attention. While the surgeon is taking position on the microscope, his/her eyes are placed onto the binocular section of the microscope; on the other hand hands are on the surgical field by holding the relevant surgical tools. The microscope that occupies the space between the eye and the hand increases the distance between the eye- hand in a stable position and it decreases the motion ability. The surgical microscope focuses on a point of the operation field, because the device is big and occupies the operation field fully; the tissue control out of focus in terms of microscopic and macroscopic aspects is lost. Present surgical microscopes are devices which are difficult to use.

Aim of the Invention

The invention is a new model designed alternatively to the surgical microscopes. When it is compared to the big surgical microscopes, since it is very smaller and lighter, it saves place within the operating room. It is easy to cover with a sterile sheath. After the sterile sheath is covered onto it, the possibility of giving damage to the position of the other surgical equipment and the patient is very low due to its size. Its operation is easy and it saves from personnel and time for its assembly. Together with the image detection and zoom unit consisting of the acrobat arms and integrated lenses fixed to the position adjustment units, sufficient zoom and resolution in the surgical field is provided and fixed by means of preferably USB connected smart display and control. Because there is no binocular system in the big microscopes which requires surgeon placing his/her eyes in a stable manner, the surgeon does not have a stable position and behaves at will thus a surgical comfort is provided. The hand-eye coordination is protected and used in a better manner because there is no system in between. While the new system transmits the operation field with a smaller zoom system into the smart display, since it does not cover the top portion of the surgical field, it provides to establish both macroscopic and microscopic control. Also in case the device fails, because the binocular system and smart display system can be separated from each other, it can be directed to the relevant technical service in a fast manner because it is easy to transport. The developed system is easy to use and more practical.

Detailed Description of the Invention

The invention aims to provide both macroscopic and microscopic field control instead of only microscopic control by means of transmitting the image in the image perception and zoom unit (2) with a smaller structure instead of the big microscopes used in the microsurgery operations, into preferably USB-mediated integrated smart display (3) and to enable more comfortable movement of the surgeon. In the microscopic displaying device (1 ), in order to display the surgical operation field, there are self-illuminated image perception and zoom unit (2), smart touchscreen (3) with high resolution with preferably usb connection wherein the image received from this unit is transmitted, at least eight keyed controller (4) which is adjacent to this display (3), can enable zoom, focus and light adjustments of the lenses in the image perception and zoom unit (2), comprises photograph and video recording options, herewith image perception and zoom unit (2), position adjustment units (5) which are fixed to the display (3) and to the controller (4) adjacent to the display and provides motion ability to these units around their axes, the flexible acrobat arms (6) which extends between the position adjustment units (5) and the electronic control unit (7), provides motion ability to the display (3) on the operation field by the image perception and zoom unit (2) and provides its having a stable position, the electronic control unit (7) which provides connection starting from the image perception and zoom unit (2), display (3) and controller (4), between the units of the connection cables passing through the position adjustment units (5) and flexible acrobat arms (6) and provides energy and the assembly units (8) integrated to the electronic control unit (7) for fixing said parts preferably to the operating table or to a stable place.

The image perception and zoom unit (2) has a cylindrical structure manufactured from a rigid plastic with preferably 10 cm length and 2 cm diameter. This cylindrical structure consists of 2 separate structures within itself. The first one is preferably 7 cm long, this structure is constituted by appropriate edged and with required number of lenses and preferably it has 25 fold zooming characteristic. Also at the sides of these sequential lenses, there are step motors which are controlled via the controller (4) unit for zooming and focusing functions in an optical manner or there are 2 separate apparatuses for zoom and focus by means of manual adjustment. The second one is a camera which has sensors with high quality view capturing feature which provides transmitting the received view from these optics into a digital medium in an instant and high quality manner. These two structures will be combined with preferably c or cs mount heads which are placed on the end of the camera. Therefore, the most sensitive two parts of the microscopic displaying device (1 ) is brought to a durable and easily usable condition by means of housing within a cylindrical structure manufactured from a rigid plastic. Therefore the image perception and zoom unit (2) has an ergonomic structure and dimensions which can be grasped by hand. Due to the fact that big microscopes have heads with approximately a human head size and its binocular usage difficulty, only microscopic field control can be obtained within the operation field. The image zoom and perception unit (2) provides to obtain both macroscopic and microscopic field control. Together with this characteristic, the surgeon is not left within a stable position, a comfortable operation opportunity is allowed. Together with an appropriate lens assembly with 50 cm height within the operation field, with at least 25 fold zoom ratio, it allows an operation with a displaying quality substantially similar to the big surgical microscopes. Also there are xenon light sources which are within the rigid plastic at the lower end of the image perception and zoom unit (2), are located around the lenses and provide adjustable coaxial illumination. The source of light will help displaying the operation field in a clearer manner. The display (3) has preferably 16x8 cm dimensions and is 200 gr by weight, comprises a system which has high processor that can enable instant display transmission, high resolution, preferably a digital zoom feature up to 10 folds in addition to optic zoom, a smart, touchscreen and unique software program with storing information capability via its memory. There is an integrated controller unit (4) with 8x4 cm dimension and 8 keys, adjacent to the short side of the display (3). In order to allow the lenses in the image and perception unit (2) in the controller (4) unit performing their zooming functions optically preferably with 25 X ratio, it consists of a system with 8 keys as the following; 2 keys with +/- characteristic, 2 keys with +/- characteristic in order to perform focusing function, 2 keys with +/- characteristic in order to increase-decrease the brightness of the xenon light source placed under the image and perception unit (2) and 2 keys for recording photo or camera in order to enable recording the image transmitted to the display (3) as a video or a photograph within the memory of the display. At the first touch to the video record key on the controller (4) unit, the record is started, on the other hand in order to terminate the record, it is required to touch the video record key for the second time and thus stored video or videos are stored within the memory card of the display in an organized manner. The photograph storing system has a single frame pose shoot feature with one touch, the photo or photos taken will be stored within the memory card of the display in an organized manner. The lower limit of the position adjustment units (5) are integrated with the image perception and zoom unit from the upper limit of the display (3). Thanks to their movable head feature, the position adjustment units (5) allow movement of the image perception and zoom unit (2) and the display (3) units to the front-back, to the right-left, to up- down within a 270 ⁰ elliptical rotation within their fixed positions. The lower limit of the acrobat arm units (6) are integrated to each other from the upper limit of the position adjustment units (5). The upper limit of the acrobat arm units (6) are integrated to the electronic control unit (7). The acrobat arm units (6) has a flexible characteristic between the position that it enters to the electronic control unit (7) and the position that it reaches to the position adjustment units (5), thus together with its movement to the front-back, to the right-left, to up-down and its 270 ⁰ rotational movement capability, it can bring the image perception and zoom unit (2), the display (3) and the adjacent controller (4) to a required position on the operating field and can it has the characteristic of being stable in this position. The acrobat arm units (6) have preferably 1 meter length, a spiral and a flexible structure with metal-plastic mixture. Having such features, the acrobat arm unit (6) and the position adjustment unit (5) enables to bring and fix the image perception and zoom unit (2) and the display (3) to a required position manually on the surgical field in a simple manner. Thus the surgeon can be able to work in the most comfortable position around the operation field and the system can be able to take its most appropriate position. In order to transmit information and energy from the image perception and zoom unit (2), display (3) and controller (4), cable connections with USB end reach to the electronic control unit (7) by passing through the position adjustment units (5) and acrobat arm (6) units. The electronic control unit (7) not only enables the connection between the image perception and zoom unit (2), the display (3) and the controller (4) but also enables the required energy to this system. The system is combined in the assembly unit (8) finally as a whole. In order to position the assembly unit (8) in a stable manner, it is fixed to the side of the operating table with appropriate clips having simple hot-plug system. This microscopic displaying device (1 ) is placed with an optimum distance and due to its small structure it does not occupy space in the surgical field and it enables a comfortable working area with the surgical tools.
