Abstract: The present disclosure provides a surgical navigation system and an instrument guiding method for the same. The instrument guiding method includes: receiving three-dimensional (3D) space information of a predetermined instrument path of an instrument; transmitting the 3D space information to a processing unit such that the processing unit converts the three-dimensional space information to two-dimensional (2D) space information by using a projection model algorithm; and receiving, by at least two image-type projecting units, the 2D space information and projecting at least two patterns into a physical space, wherein the at least two patterns intersect each other to form an intersection area.

Abstract: A system and a method for manufacturing a dental implant surgical guide are disclosed. The dentist may obtain a cast model of the patient's jaw and a plurality of CT images of the jawbone and teeth by CT scanning. The system includes a cast model navigation device, a controlling module, and a computer system. The navigation device includes an articulated arm capable of holding a tool and a plurality of braking elements. The articulated arm is operated to measure the positions of markers on the cast model to provide the position registration between the cast model and the plurality of CT images. Once registered, the articulated arm is operated to simulate the target implant position under the guidance of the CT images. The arm can then be locked via the plurality of braking elements controlled by the controlling module for manufacturing of the surgical guide.

Abstract: A system and a method for manufacturing a dental implant surgical guide are disclosed. The dentist may obtain a cast model of the patient's jaw and then make a CT scan appliance with a plurality of radiopaque markers out of the cast model. The patient wears the appliance under CT scanning to obtain a plurality of CT images of the jawbone and teeth. The system comprises a cast model navigation device, a controlling module, and a computer system. The navigation device comprises an articulated arm capable of holding a tool and a plurality of braking elements. The computer system comprises a memory storing a software program and a processor. The articulated arm is operated to measure the positions of the markers to provide the position registration between the cast model and the plurality of CT images. Once registered, the articulated arm is operated to simulate the target implant position under the guidance of the CT images.

Abstract: A surgical positioning device comprises a base, an upper moving structure, a lower moving structure, an auxiliary operating element, and a plurality of encoders. The upper moving structure and the lower moving structure are coupled to the base individually, such that the upper moving structure and lower moving structure may move on a first plane and a second plane, respectively. The first plane is substantially parallel to the second plane. Each of the upper moving structure and lower moving structure comprise a holder respectively for holding the auxiliary operating element. The plurality of encoders measure the movement of the moving elements of the upper moving structure and the lower moving structure. A surgical tool may be adjusted and positioned by operating the auxiliary operating element to move the upper moving structure and the lower moving structure on the different planes, respectively.

Abstract: An image guided navigation system comprises a memory, a locator, a processor and a display. The memory stores a plurality of CT images and a software program. The locator is capable of indicating a direction to a surgical area, and the indicated direction of the locator is defined as a first direction. The processor is electrically connected to the memory and the locator. At least one corresponding image corresponding to the first direction is obtained from the plurality of CT images by the processor executing the software program. The at least one corresponding image comprises at least one simulated fluoroscopic image. The display is capable of showing the at least one corresponding image.

Abstract: The invention is disclosed to a control apparatus of catheter feeder. It comprises two rotatable mechanisms and a transmittal device that can propel the guidewire into continuous motion comprising moving forward, moving backward, moving clockwise, and moving counter-clockwise. The invention comprises of a square frame and three gears that are meshed together and are referred to the first, second, and third gear, respectively. At the front of the third gear are the first and second sets of the idle wheels that can hold the guidewire tightly. The invention employs the mechanical gears to control movement of the guidewire.

Abstract: A surgical positioning device comprises a main part and at least three fiducial markers. Said fiducial markers have a CT number ranging from 1,000 to 3,000 and may produce dense, bright, and artifact-free spots on a CT scanning image.

Abstract: The present invention relates to a system integrating three-dimensional anatomical information with a cast model. The system combines the advantages of a digitalized three-dimensional image and the virtues of a cast model. Users may utilize a fully integrated environment provided by the present invention to make treatment planning more promptly and accurately.
