摘要:
Disclosed is a medical intervention apparatus. The medical intervention apparatus includes a needle rotation unit configured to include a first needle rotation member, a second needle rotation member that is disposed to be separated from the first needle rotation member, and a first driver that drives the first and second needle rotation members to rectilinearly move in opposite directions and a needle insertion unit configured to insert a needle, which is inserted between the first needle rotation member and the second needle rotation member, into a target.

Disclosed is a apparatus for generating a needle insertion path for an interventional robot, which provides a needle insertion path for intervention by inserting a needle. The apparatus includes a patient-side optical tool located on a patient for showing a position of an intervention target part among parts of the patient, a robot-side optical tool located on an interventional robot for showing a position of the interventional robot, and a needle path calculator configured to track positions of the patient-side optical tool and the robot-side optical tool to perform spatial registration on a local coordinate system of the patient-side optical tool based on the position of the patient-side optical tool with respect to a robot base coordinate system based on the position of the robot-side optical tool, and calculate a needle insertion path with respect to robot base coordinate system, based on a result of the spatial registration.
摘要:
Disclosed is an antenna with an extended electrical length, including radiators (110, 210, 310), (410 and 510) having S-shaped or spiral-shaped cells (112, 212, 312 and 512). The cells (112, 212, 312 and 512) are formed on the front surface of the boards (120, 220, 320, 420 and 520), and two or more of the cells are connected in series by connectors (114, 214 and 314) formed on the rear surface of the board. Furthermore, the antenna includes a ground stub (150) and a parasitic element (160) electromagnetically coupled to the radiators (110, 210, 310, 410 and 510), and has a good radiation characteristic. Furthermore, the antenna can include the cells (112, 212, 312 and 512) of different sizes and can thus have a multi-band characteristic.
