摘要： The embodiments of the present invention provide a system and method for light and shadow guided needle positioning. DICOM images of a patient are captured for identifying a point of insertion of a needle on the patient's body and a target point inside the patient's body. Needle coordinates are computed based on the captured DICOM images to position the mechanical arms. Light is projected at a particular angle on the needle to form shadows of the needle. Laser light beams are projected to form cross hair at the point of insertion. Images or videos of the point of insertion, shadow of the needle and the cross hair are captured and displayed on a monitoring unit. A virtual circle is projected on the displayed image and is aligned with the point of insertion, shadow of the needle and cross hair in order to insert the needle precisely.

摘要： A surgical visualization feedback system is disclosed. The surgical visualization feedback system comprises an emitter assembly configured to emit electromagnetic radiation toward an anatomical structure. The emitter assembly comprises a structured light emitter configured to emit a structured light pattern on a surface of the anatomical structure and a spectral light emitter configured to emit spectral light capable of penetrating the anatomical structure. The surgical visualization feedback system further comprises a waveform sensor assembly configured to detect reflected electromagnetic radiation corresponding to the emitted electromagnetic radiation and a control circuit in signal communication with the waveform sensor assembly. The control circuit is configured to receive an input corresponding to a selected surgical procedure, determine an identity of a targeted structure within the anatomical structure based on the selected surgical procedure and the reflected electromagnetic radiation, and confirm the determined identity of the targeted structure through a user input.

摘要： A surgical implant planning computer for intra-operative CT workflow, pre-operative CT imaging workflow, and fluoroscopic imaging workflow. A network interface is connectable to a CT image scanner and a robot surgical platform having a robot base coupled to a robot arm that is movable by motors. A CT image of a bone is received from the CT image scanner and displayed. A user's selection is received of a surgical screw from among a set of defined surgical screws. A graphical screw representing the selected surgical screw is displayed as an overlay on the CT image of the bone. Angular orientation and location of the displayed graphical screw relative to the bone in the CT image is controlled responsive to receipt of user inputs. An indication of the selected surgical screw and an angular orientation and a location of the displayed graphical screw are stored in a surgical plan data structure.

摘要： A medical optical fiber guidewire converter includes a first connector; a second connector; a conversing optical fiber with an overcurrent channel configured to transmit laser light and including a first and second optical fibers and a connecting optical fiber, a diameter of the first optical fiber is greater than that of the second optical fiber, the first optical fiber is connected to the first connector, and the second optical fiber is connected to the second connector; and a heat sink on the conversing optical fiber. The medical optical fiber guidewire converter couples optical fiber guidewires with different core diameters using the connecting optical fiber, thereby ensuring safety and reliability of laser light transmission in the overcurrent channel. The heat sink can absorb laser light overflowing from the conversing optical fiber and dissipate heat therefrom to reduce the temperature of and avoid thermal damage to the conversing optical fiber.
