20110004245 | Spine Fixation Device - A spine fixation device is provided. The spine fixation device includes a bone screw, a fixation carrier, and a first locking member. The fixation carrier is rotatably coupled to a fixation unit of the bone screw. The first locking member conjugates the fixation carrier and the bone screw together. A screw unit of the bone screw is implanted into a vertebra. As the fixation carrier is rotatably coupled to the bone screw, the bone screw remains fastened to the vertebra while the fixation carrier is rotated. Through rotational adjustment of the fixation carrier, U-shaped openings of the fixation carrier are adjustable in direction. Thus, the disposition angle of a rod disposed in the U-shaped openings is easily adjustable by rotating the fixation carrier. As a result, the rod can fit an angle of the spine while surgical complexity is reduced. | 01-06-2011 |
20110004249 | FLEXIBLE SPINAL FIXATION DEVICE AND ROD THEREOF - A flexible spinal fixation device and a rod thereof are provided. The flexible spinal fixation device includes at least two bone screws and a rod. The rod is fixedly coupled to the bone screws, and the bone screws are implanted into a patient's vertebrae. The rod has a flexible part and is thereby rendered flexible. After the flexible spinal fixation device is implanted into the patient's spine, the patient's spine can stoop as in a healthy condition. Moreover, vertebral stress around an injured vertebra and force between the bone screws and the rod can both be reduced. The flexible spinal fixation device also prevents premature vertebral aging and has an extended service life. | 01-06-2011 |
20110019868 | Method for Image Positioning - A method for image positioning is provided. The method is configured for positioning image data captured by a C-arm device and includes the steps of: providing an indication module, providing a database, reading the image data, comparing the image data, deriving a coordinate conversion system, and calculating the image data. Steel balls in the indication module have known template coordinates. Plural sets of template triangle data, each set composed by three of the steel balls, are stored in the database. Steel ball image data presented in the image data form indication triangle data. The indication triangle data are compared with the template triangle data to produce comparison results. The coordinate conversion system is derived from the comparison result with the highest similarity. Thus, image coordinates in the image data can be converted into and from the template coordinates via the coordinate conversion system, allowing the image to be orientated precisely. | 01-27-2011 |
20110026802 | Analysis Method for Regional Image - An analysis method for a regional image is disclosed for an image datum from a C-arm device. The analysis method includes: providing an indication module, reading the image datum, selecting a plurality of ROIs (Regions of Interest), calculating an average brightness of each of the ROIs, searching every of the steel ball image data, comparing each of the steel ball image data and analyzing each of the steel ball image data. By individually analyzing the regional image datum, the brighter or darker image signal can be excluded so that it can improve precision during searching the steel ball image data. Moreover, it is also more effective for comparing an image profile of the steel ball image datum with a real profile of the steel ball of the indication module. Thus, the steel ball image can be readily defined by its correspondence with the steel ball of the indication module. | 02-03-2011 |
20110046636 | Surgical Guide Instrument Capable of Omni-Directional Positioning and Omni-Directional Positioning Unit Thereof - A surgical guide instrument capable of omni-directional positioning and an omni-directional positioning unit thereof are provided. The surgical guide instrument includes the omni-directional positioning unit, which is coupled with the surgical instrument. The omni-directional positioning unit is configured as a pyramid, and a plurality of reflectors is deposited on vertices of the pyramid, respectively. As the reflectors of the omni-directional positioning unit are arranged as a three-dimensional pyramid, the omni-directional positioning unit can be connected in any position to the surgical instrument and be detected correctly by a surgical guide system, thereby reducing surgical complexity. | 02-24-2011 |
20110054449 | SURGICAL TOOL CALIBRATING DEVICE HAVING ELECTRONIC SENSING MODULE - A surgical tool calibrating device having an electronic sensing module is provided. The surgical tool calibrating device includes a calibration block, an electronic sensing module, and a signal communication module. The calibration block has at least one tool inserting portion, and the electronic sensing module is disposed on the bottom of the said tool inserting portion for generating an activating signal. The signal communication module is electrically connected to the electronic sensing module for transmitting the activating signal. With the electronic sensing module being provided in the calibration block, the activating signal is generated immediately when a surgical tool is inserted into the calibration block and makes contact with the electronic sensing module. Thus, the surgical tool calibrating device is activated in real time so as to determine the length of and the suitable bore diameter for the surgical tool. | 03-03-2011 |
20110054611 | Implant Structure - An implant structure for medical use is provided. The implant structure includes an implant body and a nailing portion. The implant body and the nailing portion are integrally formed as a unitary structure to thereby prevent separation between the implant body and the nailing portion which might otherwise occur after long use. The nailing portion has a bone-contacting surface with at least one barb unit formed thereon for enhancing the bonding of the implant structure and a bone, preventing the implant structure from loosening, and extending the service life of the implant structure. | 03-03-2011 |
20110075803 | IMAGE CAPTURE SYSTEM FOR RECORDING X-RAY IMAGES IN REAL TIME - An image capture system for recording X-ray images in real time is disclosed. The image capture system includes an image pickup device, a sensing module and a surgical navigation device. The sensing module is used to detect the on/off status of the image pickup device. While the image pickup device is turned on to capture an X-ray image, the sensing module transmits a notification signal to the surgical navigation device. After receiving the notification signal, the surgical navigation device records the X-ray image captured by the image pickup device and the relative position between the image pickup device and the patient in real time. Thus, the real-time recording of the relative position between the image pickup device and the patient will prevent inaccurate image reading that occurs when the patient's position and image pickup device shift after the X-ray image has been captured. | 03-31-2011 |
20110087233 | METHOD FOR GUIDING SYMMETRIC IMPLANTATION OF BONE SCREWS - A method for guiding symmetric implantation of bone screws is provided. The method includes the steps of: providing a spinal image of a spine, wherein the spine has a first bone screw implanted in one side of a spinous process of the spine; obtaining a first implanting information of the first bone screw; setting a reference line in the spinal image; generating a second implanting information by mirroring the first implanting information with respect to the reference line; and guiding a second bone screw to be implanted in the other side of the spinous process according to the second implanting information. The method generates a second implanting information that is based on and symmetric to the first implanting information, thus allowing the bone screws to be precisely implanted in both sides of the spinous process and aligned with each other in the same transverse section of the spinous process. | 04-14-2011 |
